Description:
HARD SURFACE CLEANING COMPOSITIONS COMPRISING ALKOXYLATED PHENOLS AND PERFUMES AND CLEANING PADS AND METHODS FOR USING SUCH

CLEANING COMPOSITIONS

FIELD

The present disclosure is generally directed to a hard surface cleaning composition and method for providing both freshness and performance benefits, such as scent intensity and longevity and hard surface shine, of a cleaning composition on a hard surface using perfume raw materials (PRMs) in an aqueous carrier.

BACKGROUND

Hard surface cleaning compositions are used for cleaning and treating hard surfaces. Preferably, the hard surface cleaning composition is formulated to be an“all purpose” hard surface cleaning composition. That is, the hard surface cleaning composition is formulated to be suitable for cleaning a variety of surfaces. However, it historically has been challenging to formulate a hard surface cleaning composition which effectively cleans tiles, and more delicate surfaces such as wood, stainless steel, linoleum, marble, and the like while delivering freshness benefits in a phase stable formulation without compromising cleaning. Typically, freshness benefits in aqueous cleaning compositions are achieved by the emulsification of highly hydrophobic perfumes with high level of surfactants which then negatively affect cleaning and shine benefits of the treated surface. For example, although surfactants are used, the concentrations need to be minimized otherwise the surfactants may leave residue and result in low shine, and an impression that the surface is not yet sufficiently clean. Solvent levels are also best minimized to avoid environmental considerations or negatively impact on scent. Additionally, many solvents used are high Volatile Organic Compounds (VOC). VOC materials pose challenges for negatively impacting perfume compositions by affecting their scent perception, also known as perfume’s character, as well as concerns around flashpoint regulations. Given these challenges, formulators typically avoid elevated levels of solvents and surfactants, which in turn minimizes the use or concentration of relatively more hydrophobic PRMs. This reduces the breadth of available PRMs and thus scent experiences to users. These challenges are exacerbated when formulations contain especially high levels of water and/or high levels of PRMs.

Therefore, there is a need for a cleaning composition that provides high shine with a wide variety of scent experiences enabled by more hydrophobic PRMs while minimizing levels of solvents and surfactants.

SUMMARY

Aspects of the present disclosure include a hard surface cleaning composition comprising: at least 85% by weight of water; at least 0.0015% of by weight of alkoxylated phenol; and a perfume, wherein the perfume comprises at least 60% by weight of the Perfume Raw Materials having ClogP greater than 1.0. The composition has a Shine Result of between 0.1 and 2.0 and an NTU of between 1 and 200.

Aspects of the present disclosure also include methods of improving shine of a hard surface, including the steps of wetting the hard surface with the hard surface cleaning composition and removing the cleaning composition from the hard surface with a disposable dry cleaning wipe.

Yet another aspect of of the present disclosure also include a disposable premoistened pad for cleaning hard surfaces including a substrate and the liquid hard surface cleaning composition. The substrate is impregnated with the cleaning composition

Aspects of the present disclosure also include a cleaning implement including a handle; a plastic head; a cleaning pad removably connectable with the plastic head; a reservoir connected with or separated from the handle; and the cleaning composition disposed in the reservoir.

DETAILED DESCRIPTION

Perfume raw materials (PRMs) are typically formulated with water to make cleaning compositions. However, because of the hydrophobic nature of PRMs, solvents and/or surfactants are used to solubilize and emulsify the PRMs in formulations with high water content. Solvents suitable for solubilizing PRMs typically include alcohols, polyols and mixtures thereof.

The present invention is based on the surprising discovery that the cleaning composition of the present invention comprising high levels of water, perfume and relatively low levels of alkoxylated phenol can improve solubility of a perfume PRMs having a ClogP greater than 1.0 in water content thereby providing phase stable cleaning compositions with higher perfume intensity and longevity.

The alkoxylated phenol may be an ethoxylated phenol. Having the combination of PRMs and alkoxylated phenol enables a phase stable cleaning composition and a wider range of PRMs may be formulated.

In the following description, the composition described is a floor cleaning composition. However, it is contemplated that the composition may be configured for use in a variety of applications to provide cleaning and freshness on hard surfaces or other inanimate surfaces.

Prior to describing the present invention in detail, the following terms are defined for clarity. Terms not defined should be given their ordinary meaning as understood by a skilled person in the relevant art.

The term“inanimate surface” as used herein refers to surfaces including but not limited to household surfaces such as countertops, floors, garbage cans, ceilings, walls, carpet padding, air filters, and the like.

The term“ClogP” as used herein refers to a calculated logP (“ClogP”) value of a volatile material such as for example a perfume raw material. An octanol/water partition coefficient of a volatile material is the ratio between its equilibrium concentrations in octanol and in water. The partition coefficients of the perfume material used in a cleaning composition may more conveniently be given in the form of its logarithm to the base 10, logP. The ClogP is determined by the fragment approach of Hansch and Leo (cf, A. Leo, in Comprehensive Medicinal Chemistry, vol. 4, C. Hansch, P. G. Sammens, J. B. Taylor and C. A. Ramsden, Eds., p. 295, Pergamon Press, 1990). The term“odor detection threshold” as used herein refers to the lowest concentration of a perfume composition that is perceivable by the human sense of smell and it is correlated to longevity of the perfume composition.

The term“essentially free of’ a component means that no amount of that component is deliberately incorporated into the respective premix, or composition. Preferably,“essentially free of’ a component means that no amount of that component is present in the respective premix, or composition, but may be present as trace impurities.

As used herein,“isotropic” means a clear mixture, having little or no visible haziness, phase separation and/or dispersed particles, and having a uniform transparent appearance.

As defined herein,“stable” means that no visible phase separation is observed for a premix kept at 25°C for a period of at least two weeks, or at least four weeks, or greater than a month or greater than four months, as measured using the Floe Formation Test, described in USPA 2008/0263780 Al.

By "Low volatile organic compound hard surface cleaning composition", it is meant herein a finished product having low volatile organic compound (“VOC”) content like, for example, a maximum of 0.5% by weight of the composition of VOCs, however, it is noted that fragrance is exempted from this value up to 2% by the weight of the finished product.

All percentages, ratios and proportions used herein are by weight percent of the premix, unless otherwise specified. All average values are calculated“by weight” of the premix, unless otherwise expressly indicated.

All measurements are performed at 25°C unless otherwise specified.

Unless otherwise noted, all component or composition levels are in reference to the active portion of that component or composition, and are exclusive of impurities, for example, residual solvents or by-products, which may be present in commercially available sources of such components or compositions.

I. Liquid Hard Surface Cleaning Composition

By "liquid hard surface cleaning composition,” it is meant herein a liquid composition for cleaning and hard surfaces found in households, especially domestic households. Surfaces to be cleaned include kitchens and bathrooms, e.g., floors, walls, tiles, windows, cupboards, sinks, showers, shower plasticised curtains, wash basins, WCs, fixtures and fittings and the like made of different materials like ceramic, vinyl, no-wax vinyl, linoleum, melamine, glass, steel, kitchen work surfaces, any plastics, wood, plasticised wood, metal or any painted or varnished or sealed surface and the like. Household hard surfaces also include household appliances including, but not limited to refrigerators, freezers, washing machines, automatic dryers, ovens, microwave ovens, dishwashers and so on. Such hard surfaces may be found both in private households as well as in commercial, institutional and industrial environments.

A. Water

A liquid hard surface cleaning composition of the present invention may comprise at least 85%, by weight of the composition of water. The water may be in an amount from 85% to 99.5%, from 90% to 99.5%, from 95% to 99.5%, 95%, or different combinations of the upper and lower percentages described above or combinations of any integer in the ranges listed above, of water by weight of the composition. The water may be distilled, deionized or tap water. Having high levels of water enable the cleaning composition to wet and spread through cleaning surface for the purpose of cleaning while reducing the amount of residue left behind, resulting in improved shine.

B. Alkoxylated phenol

The hard surface cleaning composition has alkoxylated phenol in a level of at least 0.0015% by weight of the composition. Alkoxylation is a chemical reaction that involves the addition of an epoxide which is an alkoxylating agent to another compound. Epoxides may be lower molecular weight epoxides (oxiranes) such as ethylene oxide, propylene oxide and butylene oxide. These epoxides are capable of reacting with hydroxyl generally under base catalysis, causing a ring opening and the addition of an oxyalkylene group. The resulting compound contains a hydroxyl group, so a varied number of moles of oxide can be added. Alkoxylation of a phenol-containing compound relates to reaction of mixtures of oxides with the phenol containing compound which produces hydroxy alkyl phenyl ether compounds (also known as alkoxylated phenols). A process for alkoxylation of phenols is described in U.S. Pat. No. 4,261,922. A phenol-containing compound has the following structure and the molecular formulae is ObEEOH.

The alkoxylated phenol may be selected from the group consisting of: propoxylated phenol, ethoxylated phenol, and combinations thereof, preferably ethoxylated phenol.

Accordingly, the reaction of ethylene oxide with a phenol containing compound results in ethoxylated phenol as shown in the following reaction:

ROH + C2H4O ® ROCH2CH2OH, wherein ROH is phenol containing compound.

Similarly, the reaction of propylene oxide with a phenol containing compound results in propoxylated phenol as shown in the following reaction:

ROH + n OCH2CHCH3 ® R(OCH2CHCH3)nOH, wherein ROH is phenol containing compound. Ethoxylation and propoxylation of phenol containing compounds may be performed according to known processes.

In the following description, the alkoxylated phenol described is an ethoxylated phenol. However, it is contemplated that other alkoxylated phenols, such as propoxylated, butoxylated, or mixtures thereof, may be configured for solubilizing the PRMs described hereinafter as long as the alkoxylated phenol is soluble in water and solubilizes the PRMs in water. The ethoxylated phenol may be in an amount of at least 0.0015%, preferably from 0.0015% to 9%, 0.0015% to 3.5%, more preferably, 0.0015% to 2%, even more preferably 0.0015% to 1.5%, by weight of the cleaning composition.

The ethoxylated phenol may have a structure according to Formula I:

wherein n is selected from 0 to 20, preferably from 5 to 15, more preferably from 5 to 10, even more preferably from 5 to 7; preferably n is an average value of from 5 to 15, preferably from 5 to 10, more preferably from 5 to 7.

Referring to Formula I,“n” is a numerical value corresponding to a number of ethoxylates in the ethoxylated phenol and defines the ethoxylate chain of the ethoxylated phenol. Without wishing to be bound by theory, the ethoxylated phenol for the cleaning composition according to the present invention may have different ethoxylates have ethoxylate chains of differing lengths to meet different cleaning product specifications in order to be both water-soluble and oil-soluble in a cleaning composition which has a high level of water and a perfume composition having at least 60% of PRMs having a ClogP > 1.

Ethoxylated phenols commercially available from Dow under the commercial names of Dowanol™ Glycol Ethers are set out in Table 1 below. As shown in the data described hereinafter in the Examples, use of ethoxylated phenols in which n is an average value from 5 to 15 results in a clear composition (see Example 6) relative to comparative ethoxylated phenols in which n is an average value from 1 to 2.

I. Quaternary Compound

The liquid hard surface cleaning composition may comprise a quaternary compound. Preferably, the liquid hard surface cleaning composition comprises the quaternary compound at a level of from 0.001 to 2 %wt%, more preferably from 0.002 to 0.5 wt%, most preferably from 0.005 wt% to 01 wt% of the composition.

Traditionally, compositions comprising quaternary compounds tend to leave unsightly filming and/or streaking on the treated surfaces. However, compositions as presently disclosed surprisingly provide improved shine and reduced streaking. Without being bound to theory this improved shine benefit is a result of the dewetting property of the solvent. Furthermore, the compositions disclosed provide high antibacterial benefit delivering 5 logs micro efficacy while still delivering high shine.

Quaternary compounds useful herein are preferably selected from the group consisting of Ce- Ci8 alkyltrimethylammonium chlorides, C6-Ci8dialkyldimethylammonium chlorides, and mixtures thereof. Preferably, the quaternary compound is selected from the group consisting of a Cs- Ci2 alkyltrimethylammonium chloride, a CVC12 dialkyldimethylammonium chloride, and mixtures thereof. Most preferably, the quaternary compound is Cio dialkyldimethylammonium chloride.

Non-limiting examples of useful quaternary compounds include: (1) Maquat® (available from Mason), and Hyamine® (available from Lonza); (2) di(C6-Ci4)alkyl di short chain (Ci-4 alkyl and/or hydroxyalkl) quaternary such as Uniquat® and Bardac® products of Lonza, (3) N-(3- chloroallyl) hexaminium chlorides such as Dowicil® and Dowicil® available from Dow; and (4) di(C8-Ci2)dialkyl dimethyl ammonium chloride, such as didecyldimethylammonium chloride (Bardac 22, Uniquat 2250 or Bardac 2250), and dioctyldimethylammonium chloride (Bardac 2050).

The quaternary compounds preferably are not benzyl quats. An example of such benzyl quat includes alkyl dimethyl benzyl ammonium chloride (Uniquat QAC). J. Nitrogen-containing polymer

The liquid hard surface cleaning composition may comprise a nitrogen-containing polymer. Nitrogen-containing polymers useful herein include polymers that contain amines (primary, secondary, and tertiary), amine-N-oxide, amides, urethanes, and/or quaternary ammonium groups. When present, it is important that the polymers herein contain nitrogen-containing groups that tend to strongly interact with the surface being treated in order to displace any present cationic quaternary compound from the surface.

Preferably, the polymers herein contain basic nitrogen groups. Basic nitrogen groups include primary, secondary, and tertiary amines capable of acting as proton acceptors. Thus, the preferred polymers herein can be nonionic or cationic, depending upon the pH of the solution. Polymers useful herein can include other functional groups, in addition to nitrogen groups. The preferred polymers herein are also essentially free of, or free of, quaternary ammonium groups.

Preferably, the polymers herein are branched polymers, especially highly branched polymers including comb, graft, starburst, and dendritic structures. Preferably, the polymers herein are not linear polymers. The nitrogen-containing polymers herein can be an unmodified or modified polyamine, especially an unmodified or modified polyalkyleneimine. Preferably, the nitrogen containing polymers herein are modified polyamines. Poly(C2-Ci2 alkyleneimines) include simple polyethyleneimines and polypropyleneimines as well as more complex polymers containing these polyamines. Polyethyleneimines are common commercial materials produced by polymerization of aziridine or reaction of (di)amines with alkylenedichlorides. Polypropyleneimines are also included herein.

Although modified polyamines are preferred, linear or branched polyalkyleneimines, especially polyethyleneimines or polypropyleneimines, can be suitable in the present compositions to mitigate filming and/or streaking resulting from such compositions containing quaternary compounds. Branched polyalkyleneimines are preferred to linear polyalkyleneimines. Suitable poly alky leneimines typically have a molecular weight of from about 1,000 to about 30,000 Daltons, and preferably from about 4,000 to about 25,000 Daltons. Such polyalkyleneimines are free of any ethoxy lated and/or propoxylated groups, as it has been found that ethoxy lati on or propoxylation of polyalkyleneimines reduces or eliminates their ability to mitigate the filming and/or streaking problems caused by compositions containing quaternary compounds.

In preferred cleaning compositions typically comprise nitrogen-containing polymer at a level of from about 0.005% to about 1%, preferably from about 0.005% to about 0.3%, and more preferably from about 0.005% to about 0.1%, by weight of the composition.

Examples of preferred modified polyamines useful as nitrogen-containing polymers herein are branched polyethyleneimines with a molecular weight of about 25,000 Daltons, and Lupasol® FG, Lupasol® SK and Lupasol® SK(A) available from BASF.

K Additional polymers

The liquid hard surface cleaning composition may comprise an additional polymer. It has been found that the presence of a specific polymer as described herein, when present, allows further improving the grease removal performance of the liquid composition due to the specific sudsing/foaming characteristics they provide to the composition. Suitable polymers for use herein are disclosed in co-pending EP patent application EP2272942 (09164872.5) and granted European patent EP2025743 (07113156.9).

The polymer can be selected from the group consisting of: a vinylpyrrolidone homopolymer (PVP); a polyethyleneglycol dimethylether (DM-PEG); a vinylpyrrolidone/dialkylaminoalkyl acrylate or methacrylate copolymers; a polystyrenesulphonate polymer (PSS); a poly vinyl pyridine-N-oxide (PVNO); a polyvinylpyrrolidone/ vinylimidazole copolymer (PVP-VI); a polyvinylpyrrolidone/ polyacrylic acid copolymer (PVP-AA); a polyvinylpyrrolidone/ vinylacetate copolymer (PVP- VA); a polyacrylic polymer or polyacrylicmaleic copolymer; and a polyacrylic or polyacrylic maleic phosphono end group copolymer; and mixtures thereof.

Typically, the liquid hard surface cleaning composition may comprise from 0.001% to 1.0% by weight of the total composition of said polymer, preferably from 0.005% to 0.5%, more preferably from 0.01% to 0.05% and most preferably from 0.01% to 0.03%. L. Perfumes

The cleaning composition comprises a perfume composition formulated in an effective amount such that it provides a desired scent characteristic and can be homogenously solubilized in the cleaning composition to deliver a consistent release profile. The perfume composition comprises at least 60% by weight of the perfume composition of Perfume Raw Materials (PRMs) having an average ClogP value greater than 1.0. The perfume composition may be in an amount of at least 0.005%, from 0.005% to 3%, from 0.005% to 1%, from 0.006% to 0.4%, or different combinations of the upper and lower percentages described above or combinations of any integer in the ranges listed above by weight of the cleaning composition. When the alkoxylated phenol is ethoxylated phenol, the perfume composition may comprise at least 8%, from 80% to 99.9%, from 80% to 95%, from 85% to 95%, by weight of the perfume composition of PRMs having an average ClogP distribution greater than 2.0, at least 2.5, more preferably greater than 3.0, even more preferably greater than 3.5; preferably an average ClogP distribution is from 2.5 to 6.0, more preferably from 3.5 to 6.0. M. Other optional ingredients

The liquid hard surface cleaning compositions may comprise a variety of other optional ingredients depending on the technical benefit aimed for and the surface treated. Suitable optional ingredients for use herein include builders, other polymers, buffers, bactericides, hydrotropes, colorants, stabilizers, radical scavengers, abrasives, soil suspenders, brighteners, anti-dusting agents, dispersants, dye transfer inhibitors, pigments, silicones and/or dyes.

The cleaning composition can be made in any suitable manner known in the art. All of the ingredients can simply be mixed together. In certain embodiments, it may be desirable to make a concentrated mixture of ingredients such as a pre-mix and dilute by adding the same to an aqueous carrier before use. In another embodiment, the ethoxylated phenol may be dispersed in one vessel containing ingredients such as water and may contain additional ingredients such as surfactants, solvent and polymers. All materials are added until fully dispersed and visually dissolved. In a separate vessel, the solubilizing materials (surfactants and solvents, and in some embodiments may contain the ethoxylated phenol) and perfume are mixed until homogenous. The solution of solubilizing materials and perfume are then added to the first mixing vessel, and mixed until homogenous.

II. Cleaning Pad

The liquid hard surface cleaning composition may be used in combination with a cleaning pad of the present disclosure. The cleaning pad may be dry and may contact a surface wetted with a cleaning composition, or the cleaning pad may be pre-moistened. The cleaning pad may comprise one or more layers.

Referring to Figs. 1A, IB and 2, the cleaning pad 10 may comprise plural layers, to provide for absorption and storage of cleaning fluid and other liquids deposited on the target surface. The target surface will be described herein as a floor, although one of skill will recognize the invention is not so limited. The target surface can be any hard surface, such as a table or countertop, from which it is desired to absorb and retain liquids such as spill, cleaning solutions, etc.

The cleaning pad 10 may comprise a liquid pervious floor sheet 14 which contacts the floor during cleaning and preferably provides a desired coefficient of friction during cleaning. An absorbent core 16, preferably comprising an absorbent gelling material (“AGM”) 16A is disposed on, and optionally joined to an inwardly facing surface of the floor sheet 14. The floor sheet may have an absorbency of at least 30%, more preferably at least 35%. It is to be appreciated that if the cleaning pad is to be used to clean a surface other than a floor, the floor sheet may be the sheet that contacts the surface to be cleaned.

The floor sheet of the cleaning pad may have a thickness from about 1 mm to about 5 mm, more preferably about 1.5 mm to about 3.0 mm and most preferably about 1.2 mm.

A smoothing strip 12 may be disposed on the outwardly facing surface of the floor sheet 14. Optionally, a back sheet 18 may be joined to the core 16 opposite the floor sheet 14, to provide for attachment of the cleaning pad 10 to an implement 30. The back sheet 18 may have an outwardly facing surface with one or more attachment strips 20 to particularly facilitate attachment to an implement 30. The cleaning pad 10 may be generally planar and define an XY plane and associated X, Y axes. The Z axis is perpendicular thereto and generally vertical when the cleaning pad 10 is in use on a floor.

If desired, the core 16 may comprise AGM 16A to increase the absorbent capacity of the cleaning pad 10. The AGM 16A may be in the form of particles may be distributed within the cleaning pad 10 in such a manner to avoid rapid absorbency and absorb fluids slowly, to provide for the most effective use of the cleaning pad 10. The AGM 16A also entraps dirty liquid absorbed from the floor, preventing redeposition. If desired foam absorbent material or fibrous material may be incorporated into the core 16.

Examining the cleaning pad 10 in more detail, the cleaning pad 10 may comprise plural layers disposed in a laminate. The lowest, or downwardly facing outer layer, may comprise apertures to allow for transmission of liquid therethrough and to promote the scrubbing of the target surface. One, two or more core 16 layers may provide for storage of the liquids and may comprise the absorbent gelling materials. The cleaning pad 10 may have an absorbent capacity of at least 10, 15, or 20 grams of cleaning solution per gram of dry cleaning pad 10, as set forth in commonly assigned US Patent 6,003,191 and 6,601,261.

The optional top, or upwardly facing layer, is a back sheet 18, and may be liquid impervious in order to minimize loss of absorbed fluids and to protect the user’s hand if the cleaning pad 10 is used without an implement 30. The top layer may further provide for releasable attachment of the cleaning pad 10 to a cleaning implement 30. The top layer may be made of a polyolefmic film, such as LDPE. A suitable back sheet 18 comprises a PE/PP film having a basis weight of 10 to 30 gsm.

Attached to the back sheet 18 may be one or more optional attachment strips 20. The attachment strips 20 may comprise adhesive, preferably pressure sensitive adhesive, or may loops for removable attachment to complementary hooks on an implement 30. Suitable loop attachment strips 20 may comprise a laminate of PE film and Nylon loops.

The back sheet 18 and floor sheet 14 may be peripherally joined, as is known in the art. This arrangement creates a pocket for securely holding the core 16. The core 16 may be juxtaposed with, and optionally joined to the respective inwardly facing surfaces of the floor sheet 14 and back sheet 18.

The core 16 may comprise a single layer or two or more layers. If plural layers are selected for the core 16, the width of the layers may decrease as the floor sheet 14 is approached, as shown. The core 16 may comprise airlaid cellulose and optionally polymer fiber, as available from Glatfelter of York, PA. If two airlaid cellulose core 16 layers are selected, each layer of the core 16 may have a basis weight of at least about 75, 100, 125, 150, 175, 200, or 225 gsm and less than about 300 gsm.

Preferably each layer of the core 16 comprises AGM 16A. The AGM 16A may absorb at least 10, 15 or 20 times its own weight. The AGM 16A may be blown into the airlaid core 16 layer during manufacture as is known in the art. Suitable AGM 16A is available as Z3070G from Evonik of Essen, Germany. Arlaid material containing a gradient AGM 16A distribution is available from Glatfelter of York, PA.

The gradient distribution AGM 16A may be achieved by using more than one forming head. For example, an airfelt/AGM 16A line may have three forming heads. The first head may distribute a relatively large amount of AGM 16A relative to the cellulose distributed from that head. The second forming head may distribute a less amount of AGM 16A relative to the cellulose base, with this mixture being laid onto top of the first AGM 16A/cellulose base. This pattern may be repeated using as many forming heads as desired. If desired the final forming head may distribute pure cellulose and no AGM 16A. Generally, the layer from each forming head does not intermix with adjacent layers. Adhesive bonding and/or thermal bonding may hold superposed layers in place and provide structural rigidity.

Suitable core 16 layers and a suitable apparatus and process for making one or more layers of a core 16 having a gradient AGM 16A distribution are found in US 8603622 issued Dec. 10, 2013. The teachings of US 8603622 are incorporated herein by reference at column 5, lines 8 - 14 for the teaching of a suitable core 16 layer and at Figs. 3 - 4, with the accompanying discussion at column 16, line 41 to column 17, line 59 for the teaching of production devices suitable to make a core 16 layer for the present invention.

If two airlaid cellulose core 16 layers are selected, the lower core layer 16L, juxtaposed with the floor sheet 14, may comprise about 10 to 20 weight percent AGM 16A, with about 15 percent being found suitable. The upper core layer 16U, juxtaposed with the optional back sheet 18, if any, may comprise about 20 to about 30 weight percent AGM 16A, with about 25 percent being found suitable. The total core 16, with all layers thereof considered, may comprise 5 to 50 w%, or 10 to 45 w% AGM 16 A, the amount and gradient distribution of AGM 16A being found helpful for the present invention. The percentage of AGM 16A, as described and claimed herein refers to the weight percentage of AGM 16A in that particular core 16 layer (16U or 16L), without regard to the floor sheet 14, back sheet 18, smoothing strip 12 or attachment strips 20.

Each core layer 16L, 16U and particularly the upper core layer 16U may be further stratified to provide greater absorbency benefit. The upper core layer 16U may have three strata, as formed. The strata may comprise 0, 25, and 50 weight percent, monotonically increasing as the back sheet 18, if any, is approached, to provide a gradient distribution.

Generally, it is desired that the upper core layer 16U comprise more AGM 16A, on both an absolute basis and a weight percentage basis than the lower core layer 16L. The arrangement provides the benefit that gel blocking in the lower core layer 16L does not prevent full absorption of liquid from the target surface and that liquids are transported upwardly and away from the floor sheet 14.

Any arrangement that provides more AGM 16A, preferably on an absolute basis or optionally on a weight percentage basis is suitable. Alternatively, either core 16 layer or a single core 16 layer may have increasing AGM 16A concentration in the Z direction.

Any such process, as is known in the art, or arrangement, which provides for increasing AGM 16A in the Z direction as the back sheet 18 is approached is herein considered an AGM 16A gradient. It is to be recognized that the AGM 16A gradient may be smooth, comprise one or more stepwise increments or any combination thereof.

The floor sheet 14 may comprise a discrete apertured nonwoven having a basis weight of about 20 to about 80 gsm and particularly about 28 to 60 gsm. The floor sheet 14 may be hydrophobic and made of synthetic fibers. A suitable floor sheet 14 is a 60 gsm PE/PP discrete apertured spunbond nonwoven available as SofSpan from Fitsea of Simpsonville, SC. The floor sheet 14 may have a contact angle of 101 to 180 degrees with water.

The floor sheet 14 may comprise a smoothing strip 12. The smoothing strip 12 may have a width less than the floor sheet 14 and may comprise at least about 10, 20, 30, 40, 50, 60 or 70% of the floor sheet 14 width. The smoothing strip 12 may have a width of at least 10, 20, 30, 40, 50, 100, 150, 200, 250, mm and less than 70, 80, 100, 200 or 300 mm, with a width of 24 to 44 mm being suitable and a width of 34 mm being preferred.

The smoothing strip 12 may be hydrophilic. As used herein hydrophilic means having a contact angle of 0 to 100 degrees, as measured by the test method set forth herein. The smoothing strip 12 may particularly have a contact angle of 30 to 100 degrees and more particularly 55 to 90 degrees. The smoothing strip 12 may comprise at least 50% cellulosic content to be hydrophilic.

More particularly, a suitable smoothing strip 12 may comprise a laminate of cellulose fibers and synthetic fibers. Such a laminate is believed to be helpful in attaining the performance of the cleaning pads 10 described herein. The cellulose fiber lamina may be outwardly facing, to provide friction and absorbency on the floor. The synthetic fiber layer may be positioned on contacting relationship with the floor sheet 14 to provide integrity during use.

A 23 gsm tissue and 17 gsm polypropylene spunbond hydroentagled, sold as 40 gsm Genesis tissue by Suominen of Helsinki, Finland has been found to be a suitable smoothing strip 12. Another suitable smoothing strip 12 may comprise 28 gsm tissue and 17 gsm polypropylene spunbond hydroentagled, sold as 45 gsm Hydratexture tissue by Suominen.

The smoothing strip 12 may have a surface texture less than 0.5 mm, 0.4 mm or less than 0.3 mm and even be essentially 0 mm. Surface texture is measured as the peak to valley distance, independent of the smoothing strip 12 thickness. A surface texture of less than 0.5 mm is believed to minimize streaking during cleaning, particularly when the floor dries and more particularly when a dark floor dries.

B. Wipe

The cleaning pad may be in the form of a cleaning wipe. The cleaning wipe may be used as a pre- moistened cleaning wipe or a dry wipe for use with a cleaning composition.

If the cleaning wipe is pre-moistened, it is pre-moistened with a cleaning composition, as described in further detail above, which provides for cleaning of the target surface, such as a floor, but yet does not require a post-cleaning rinsing operation.

The cleaning wipe used in conjunction with this cleaning composition may comprise natural or synthetic fibers. The fibers may be hydrophilic, hydrophobic or a combination thereof, provided that the cleaning wipe is generally absorbent to hold, and express upon demand, the above described cleaning composition. In one embodiment, the cleaning wipe may comprise at least 50 weight percent or at least 70 weight percent cellulose fibers, such as air laid SSK fibers. If desired, the cleaning wipe may comprise plural layers to provide for scrubbing, liquid storage, and other particularized tasks for the cleaning operation.

A cleaning wipe may have a thickness from about 1 mm to about 5 mm, more preferably about 1.5 mm to about 3.0 mm and most preferably about 1.2 mm.

The cleaning wipe may be loaded with at least 1, 1.5 or 2 grams of the cleaning composition, as described above, per gram of dry substrate, but typically not more than 5 grams per gram.

Optionally, the cleaning wipe may further comprise a scrubbing strip. A scrubbing strip is a portion of the cleaning wipe which provides for more aggressive cleaning of the target surface. A suitable scrubbing strip may comprise a polyolefmic film, such as LDPE, and have outwardly extending perforations, etc. The scrubbing strip may be made and used according to commonly assigned US patents 8,250,700; 8,407,848; D551,409 S and/or D614,408 S. A suitable pre-moistened cleaning wipe maybe made according to the teachings of commonly assigned US patents 6,716,805; D614,408; D629,211 and/or D652, 633.

III. Cleaning Implement

The cleaning pad 10 and cleaning composition may be used by hand or with a cleaning implement 30. Referring to Fig. 3, the cleaning implement 30 may comprise a plastic head 32 for holding the cleaning pad 10 and an elongate handle 34 connected thereto. The handle 34 may comprise a metal or plastic tube or solid rod.

The head 32 may have a downwardly facing surface, to which the cleaning pad 10 may be attached. The downwardly facing surface may be generally flat, or slightly convex. The head 32 may further have an upwardly facing surface. The upwardly facing surface may have a universal joint to facilitate connection of the elongate handle 34 to the head 32.

A hook and loop system may be used to attach the cleaning pad 10 directly to the bottom of the head. Alternatively, the upwardly facing surface may further comprise a mechanism, such as resilient grippers, for removably attaching the cleaning pad 10 to the implement 30. If grippers are used with the cleaning implement 30, the grippers may be made according to commonly assigned US patents 6,305,046; 6,484,346; 6,651,290 and/or D487,173. The cleaning implement may further comprise a reservoir for storage of the cleaning composition, a described in further detail above. The reservoir may be replaced when the cleaning composition is depleted and/or refilled as desired. The reservoir may be disposed on the head or the handle of the cleaning implement of the reservoir may be separate from the cleaning implement. The neck of the reservoir may be offset per commonly assigned U.S. Patent No. 6,390,335. The reservoir may be in the form of a spray bottle.

The cleaning implement 30 may further comprise a pump for dispensing cleaning solution from the reservoir onto the target surface, such as a floor. The pump may be battery powered or operated by line voltage. Alternatively, the cleaning solution may be dispensed by gravity flow. The cleaning solution may be sprayed through one or more nozzles to provide for distribution of the cleaning solution onto the target surface in an efficacious pattern.

If a replaceable reservoir is utilized, the replaceable reservoir may be inverted to provide for gravity flow of the cleaning solution. Or the cleaning solution may be pumped to the dispensing nozzles. The reservoir may be a bottle, and may be made of plastic, such as a polyolefin. The cleaning implement 30 may have a sleeve (36), which removably receives the bottle, or other reservoir. The cleaning implement 30 may have a needle, optionally disposed in the sleeve (36) to receive the cleaning solution from the bottle. The bottle may have a needle pierceable membrane, complementary to the needle, and which is resealed to prevent undesired dripping of the cleaning solution during insertion and removal of the replaceable reservoir. Alternatively, or additionally, if desired, the implement 30 may also provide for steam to be delivered to the cleaning pad 10 and/or to the floor or other target surface.

A suitable reservoir of cleaning solution and fitment therefore may be made according to the teachings of commonly assigned US Patents 6,386,392, 7,172,099; D388,705; D484,804; D485,178. A suitable cleaning implement 30 may be made according to the teachings of commonly assigned US Patents 5,888,006; 5,960,508; 5,988,920; 6,045,622; 6,101,661; 6,142,750; 6,579,023; 6,601,261; 6,722,806; 6,766,552; D477,701 and/or D487,174. A steam implement 30 may be made according to the teachings of jointly assigned 2013/0319463.

Method of cleaning a surface

Cleaning pads, cleaning wipes, and cleaning implements using cleaning pads and cleaning wipes may be used along with a liquid hard surface cleaning refreshing composition having an alkoxylated phenol for controlled emulsification of perfumes for cleaning hard surfaces.

Preferably cleaning pads, cleaning wipes, and cleaning implements using cleaning pads and cleaning wipes may be used along with a liquid surface cleaning refreshing composition having at least 85% by weight of water; at least 0.0015% of by weight of alkoxylated phenol; and a perfume, wherein the perfume comprises at least 60% by weight of the Perfume Raw Materials having ClogP greater than 1.0, are suitable for cleaning household surfaces.

For general cleaning, especially of floors, a preferred method of cleaning comprises the steps of: wetting a hard surface with a cleaning refreshing composition and removing the cleaning refreshing composition from the hard surface by wiping the hard surface with a cleaning pad or cleaning wipe of the present disclosure. The step of wetting the hard surface may involve spraying the hard surface with a liquid cleaning refreshing composition or contacting the hard surface with a pre moistened wipe or cleaning pad to wet the hard surface. A cleaning implement comprising a pre- moistened or dry cleaning pad or cleaning wipe may also be used to wet and/or remove the cleaning refreshing composition from the hard surface.

Test Methods:

A) Shine test for floor cleaning:

The shine test is done with soil mixture which consists of a mixture of consumer relevant soils such as oil, particulates, pet hair, sugar etc. The dark colored engineered hardwood flooring is soiled with the soil mixture and cleaned with the liquid hard surface cleaning composition(s) and a cleaning pad is wiped up and down for a total of six (6) times to cover the entire flooring, after letting them dry, results are analyzed by using grading scale described below.

Grading in absolute scale: and PSU Scale Versus a Reference (average of 3 graders):

0= as new /no streaks and/or film 0 = 1 see no difference 1= very slight streaks and/or film 1 = 1 think there is difference 2= slight streaks and/or film 2 = I am sure there is a slight difference

3= slight to moderate streaks and/or film 3 = I am sure there is a difference

4= moderate streaks and/or film 4 = I am sure there is a big difference

5= moderate/heavy streaks and/or film 6 heavy streaks and/or film

B) Measurement of Turbidity:

A turbidimeter is used to determine how well ingredients can solubilize and emulsify perfume. The method of measuring turbidity is described in detail in the following reference: Hach Company, 2009, 2013.,“Hach 2100Q and 2100Qis User Manual.” This method of measurement determines quantitative values of turbidity by evaluating the ratio of a primary nephelometric light scatter signal to a transmitted light scatter signal. This particular method of evaluation provides values between 0-1000NTU, where increasing NTU values indicate more turbid solutions. Thus, successful perfume emulsification will yield lower NTU values vs. unsuccessful perfume emulsification will yield higher NTU values. In between each test sample, water controls should be measured to ensure proper equipment operation.

C) Measurement of (Consumer Relevant) Panelist Perfume Intensity:

A perfume intensity panel is used to determine the perfume intensity of the cleaning compositions. The method uses trained panelist selected by their ability to discriminate perfume intensities in a 0 to 100 scale. Testing is run in glass rooms with dimensions 15 ft wide, 15 ft length and 8 ft height with aluminum floor, to further reduce the effect of residual scent and to provide a non-absorbent cleaning surface. The rooms are controlled at a temperature between 18 to 25°C ± 1°C or 65 to 78°F ± 3°F and a relative humidity is controlled between 40-65%RH ± 5% with 4 air changes per hour.

Panelists evaluate rooms in groups of 2-5 depending on the total number of panelists available with a minimum of 4 groups per test. Panelists evaluate the room scent intensity on a 0-100 scale at the predetermined intervals, for example initial to 4 hours. In order to increase the ability of the panelist to discriminate between treatments, inventive samples are compared with comparative samples or controls. The evaluations are averaged and graphed as intensity versus time.

D) Measurement of Perfume Longevity:

An olfactometer such as the Scentroid SC300 from IDES is used to determine the longevity of a perfume composition at its odor detection threshold (ODT) from the correlation of its perfume concentration in the fluid phase and its intensity and psychophysical curves perceived by trained person. The method of measuring the intensity of the fragrance, using a dynamic scale method, at concentrations higher than the ODT concentration is described in ASTM E544-99. Longevity is obtained from the combination of a first order concentration decay model and a non-lineal regression of the psychophysical curves using the Hill equation.

The method uses a first order space concentration decay model to determine the concentration of fragrance in a room or space from a dwell time after mopping at the weight fraction of perfume in the composition.

where:

C(t) is the concentration in the room of the perfume at a given time t is the dwell time after mopping

V is the room volume

Q is the room volumetric air flow rate, which can be estimated as V ACH

ACH is the number of air changes per hour

Co is the initial concentration in the room, which can be estimated as: where: w Pp is the weight fraction of perfume in the composition A is the floor surface area f is the mass per area of juice delivered to the floor during mopping MW is the molar average molecular weight of the perfume P is standard pressure R is the universal gas constant T is standard temperature

The olfactometer is used to generate psychophysical curves that correlate intensity to concentration at various dilutions of a fragrance. The intensity data is then fitted using a Hill equation nonlinear regression.

where:

I is the intensity bo, bi, b2 are fit parameters

C is the vapor phase concentration.

The longevity of a perfume concentrations is estimated from the combination of the space concentration decay model, e.g. the weight fraction of the perfume in the fluid phase, and the transformed intensity at the odor detection threshold.

E) pH measurement:

The pH is measured on the neat composition, at 25°C, using a Sartarius PT-10P pH meter with gel- filled probe (such as the Toledo probe, part number 52 000 100), calibrated according to the instructions manual.

F) Gas Chromatography / Flame Ionization Detector (GC/FID):

Distribution of ethoxylates in the comparative ethoxylated phenol samples and inventive ethoxylated phenol samples are analyzed by gas chromatography with mass selection detection and flame ionization detection (GC MSD/FID) and the distribution is expressed as a normalized FID area% for each sample.

The samples are prepared and analyzed according to the following steps: i) 13.0 (± 1.0) mg of a sample for each ethoxylated phenol is added to 1 mL of 1 mL of methylene chloride into the GC vial.

ii) The vial is capped and heated at 90 +/- 2 C for 15 mins.

iii) The samples are analyzed by gas chromatography with flame ionization detection (GC/FID) under the following conditions:

• Capillary GC Column: DB-1HT 5m x 0.25 mm ID, 0.1 pm film

• Oven Program: 50 C (0 min) - 25 C / min - 395 C (10 min), Total 23.8 min

• Column Flow: 1.0 ml/min (He), Average Velocity 34 cm/sec Injection Temp:

365 C, Sample Amount 1 pi, Split Ratio: 50: 1

• FID Temp: 400 C, H2 Flow: 40 ml/min, Air Flow 450 mL/min iv) Chromatograms are reprocessed integrating the area under only the phenyl ethoxylate peaks. Weight % is calculated by dividing the corresponding area under the curve for each phenyl ethoxylate peak by the summation of all phenyl ethoxylate areas.
