Description:
AQUEOUS SPRAY COMPOSITION

Field of the Invention The field of the present invention is fabric sprays. Background of the Invention

Consumers have increasingly busy lives, with limited time to do their laundry. On the other hand, roughly 40% of garments which go through the laundry process are not dirty and could be re-worn. This practice leads to un-necessary use of water which can be problematic particularly in water scarce regions of the world.

Various fabric re-fresh sprays have been disclosed previously. EP1495102 discloses a composition to provide controlled release of an active material. WO 200161 100 discloses a composition for controlling wrinkles in fabric. However these compositions are only concerned with particular aspects of refresh and are not sufficient coping mechanism to provide the consumers with the confidence to re-wear. There is a need for a consumer product to rejuvenate garments and return them to a 'just washed state', thereby provide the consumers with the confidence to re-wear a garment. The consumer cues for 'just washed state' are a synergistic combination of the look and feel of a garment. When looking for rejuvenation consumers desire the garments to return to the look and feel of a newly purchased state.

Summary of the Invention

According to one aspect of the present invention there is provided an aqueous fabric spray composition, comprising: a. 1 - 10 w.t. % silicone, wherein the silicone is in the form of an emulsion b. 0.1 - 1 .5 w.t.% setting polymer. According to another aspect of the present invention there is provided a method of rejuvenating fabric or returning clothes to a 'just washed' state, comprising the step of spraying the composition according to the present invention onto the fabric or clothes. According to another aspect of the present invention there is provided a method of a method of inserting a crease into a garment, without the requirement of heat, comprising the steps of:

- Spraying the composition of the present invention onto a garment

- Shaping a crease in the garment

- Leaving to dry

According to another aspect of the present invention there is provided a use of the composition according to the present invention, to rejuvenate clothes or to return clothes to a 'just washed state'.

According to another aspect of the present invention there is provided a use of the composition according to the present invention, to provide new creases to an item of clothing, without the requirement of heat.

Compositions according to the present invention provide benefits such as shape and colour restoration, a thicker, newer feel to the fabric, enhanced fragrance, protection against future creases, fibre protection and reduction in the appearance of fibrils. Not only do the compositions remove unwanted creases, they also allow for the insertion of new creases, without the need for an iron. For example, a pleated skirt of smart trousers may require the insertion of a crease. The ability to do this without an iron is beneficial for the busy consumer, who does not have time or the ability to access an iron. Furthermore, the ability to set new creases, without heat is particularly beneficial to compositions comprising volatile perfume ingredients, having a low boiling point. These volatile ingredients are often a cue for freshness and it is desirable for these to last on the fabric for as long as possible. Ironing at for example 230 degrees Centigrade would lead to the evaporation of many of these perfume ingredients. Detailed Description of the Invention

These and other aspects, features and advantages will become apparent to those of ordinary skill in the art from a reading of the following detailed description and the appended claims. For the avoidance of doubt, any feature of one aspect of the present invention may be utilised in any other aspect of the invention. The word "comprising" is intended to mean "including" but not necessarily "consisting of" or "composed of." In other words, the listed steps or options need not be exhaustive. It is noted that the examples given in the description below are intended to clarify the invention and are not intended to limit the invention to those examples per se. Similarly, all percentages are weight/weight percentages unless otherwise indicated.

The terms 'terminal position' and 'at the end of the silicone chain' are used to indicate the terminus of the silicone chain. When the silicones are linear in nature, there are two ends to the silicone chain. In this case the anionic silicone preferably contains no functional groups located on a terminal position of the silicone. When the silicones are branched in nature, the terminal position is deemed to be the two ends of the longest linear silicone chain. Preferably no functional group(s) are located on the terminus of the longest linear silicone chain.

Boiling point is measured at standard pressure (760 mm Hg). Preferably a perfume composition will comprise a mixture of blooming and substantive perfume components. The perfume composition may comprise other perfume components.

The logP of many perfume ingredients have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, Calif., contains many, along with citations to the original literature. However, the logP values are most conveniently calculated by the "CLOGP" program, also available from Daylight CIS. This program also lists experimental logP values when they are available in the Pomona92 database. The "calculated logp" (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, incorporated herein by reference). The fragment approach is based on the chemical structure of each perfume ingredient, and takes into account the numbers and types of atoms, the atom connectivity, and chemical bonding.

The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are used instead of the experimental logP values in the selection of perfume ingredients herein.

It is commonplace for a plurality of perfume components to be present in a free oil perfume composition. In the compositions for use in the present invention it is envisaged that there will be three or more, preferably four or more, more preferably five or more, most preferably six or more different perfume components. An upper limit of 300 perfume components may be applied.

The free perfume of the present invention is in the form of an emulsion. The particle size of the emulsion can be in the range from about 1 nm to 30 microns and preferably from about 100 nm to about 20 microns. The particle size is measured as a volume mean diameter, D[4,3], this can be measured using a Malvern Mastersizer 2000 from Malvern instruments. Without wishing to be bound by theory, it is believed that the free perfumes of this emulsion particle size will interact with the silicone emulsion to provide improved perfume longevity on the items being sprayed. Free oil perfume forms an emulsion in the present compositions. The emulsions may be formed outside of the composition or in situ. When formed in situ, at least one emulsifier is preferably added with the free oil perfume to stabilise the emulsion. Preferably the emulsifier is anionic or non-ionic. Examples suitable anionic emulsifiers for the free oil perfume are alkylarylsulphonates, e.g., sodium dodecylbenzene sulphonate, alkyl sulphates e.g., sodium lauryl sulphate, alkyl ether sulphates, e.g., sodium lauryl ether sulphate nEO, where n is from 1 to 20 alkylphenol ether sulphates, e.g., octylphenol ether sulphate nEO where n is from 1 to 20, and sulphosuccinates, e.g.,

sodium dioctylsulphosuccinate. Examples of suitable nonionic surfactants used as emulsifiers for the free oil perfume are alkylphenol ethoxylates, e.g., nonylphenol ethoxylate nEO, where n is from 1 to 50, alcohol ethoxylates, e.g., lauryl alcohol nEO, where n is from 1 to 50, ester ethoxylates, e.g., polyoxyethylene monostearate where the number of oxyethylene units is from 1 to 30 and PEG-40 hydrogenated castor oil.

Malodour Ingredients

Compositions of the present invention preferably comprise anti-malodour ingredient(s). Malodour ingredients may be in addition to traditional free perfume ingredients.

Anti-malodour agent may be present at a level selected from: less than 20%, less than 10%, and less than 5%, by weight of the garment refreshing composition. Suitably anti- malodour agent is present in the garment refreshing composition in an amount selected from the range of from about 0.01 % to about 5%, preferably from about 0.1 % to about 3%, more preferably from about 0.5% to about 2%, by weight of the garment refreshing composition.

Any suitable anti-malodour agent may be used. Indeed, an anti-malodour effect may be achieved by any compound or product that is effective to "trap", "absorb" or "destroy" odour molecules to thereby separate or remove odour from the garment or act as a "malodour counteractant". The odour control agent may be selected from the group consisting

of: uncomplexed cyclodextrin; odour blockers; reactive aldehydes; flavanoids; zeolites; activated carbon; a mixture of zinc ricinoleate or a solution thereof and a substituted monocyclic organic compound; and mixtures thereof.

As noted above, a suitable anti-malodour agent is cyclodextrin, suitably water soluble uncomplexed cyclodextrin. Suitably cyclodextrin is present at a level selected from 0.01 % to 5%, 0.1 % to 4%, and 0.5% to 2% by weight of the garment refreshing composition.

As used herein, the term "cyclodextrin" includes any of the known cyclodextnns such as unsubstituted cyclodextrins containing from six to twelve glucose units, especially, alpha- cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin and/or their derivatives and/or mixtures thereof. The alpha-cyclodextrin consists of six glucose units, the beta- cyclodextrin consists of seven glucose units, and the gamma-cyclodextrin consists of eight glucose units arranged in donut-shaped rings.

Preferably, the cyclodextrins are highly water-soluble such as, alpha-cyclodextrin and/or derivatives thereof, gamma-cyclodextrin and/or derivatives thereof, derivatised beta- cyclodextrins, and/or mixtures thereof. The derivatives of cyclodextrin consist mainly of molecules wherein some of the OH groups are converted to OR groups. Cyclodextrin derivatives include, e.g., those with short chain alkyl groups such as methylated cyclodextrins, and ethylated cyclodextrins, wherein R is a methyl or an ethyl group; those with hydroxyalkyl substituted groups, such as hydroxypropyl cyclodextrins and/or hydroxyethyl cyclodextrins, wherein R is a— CH2— CH(OH)— CH3 or a— CH2CH2— OH group; branched cyclodextrins such as maltose-bonded cyclodextrins; cationic cyclodextrins such as those containing 2-hydroxy-3-(dimethylamino)propyl ether, wherein R is CH2— CH(OH)— CH2— N(CH3)2 which is cationic at low pH; quaternary ammonium, e.g., 2-hydroxy-3-(trimethylammonio)propyl ether chloride groups, wherein R is CH2— CH(OH)— CH2— N+(CH3)3CI-; anionic cyclodextrins such as carboxymethyl

cyclodextrins, cyclodextrin sulfates, and cyclodextrin succinylates; amphoteric

cyclodextrins such as carboxymethyl/quaternary ammonium cyclodextrins; cyclodextrins wherein at least one glucopyranose unit has a 3-6-anhydro-cyclomalto structure, e.g., the mono-3-6-anhydrocyclodextrinse Highly water-soluble cyclodextrins are those having water solubility of at least about 10 g in 100 ml of water at room temperature, preferably at least about 20 g in 100 ml of water, more preferably at least about 25 g in 100 ml of water at room temperature. The availability of solubilized, uncomplexed cyclodextrins is essential for effective and efficient odour control performance. Solubilized, water-soluble cyclodextrin can exhibit more efficient odour control performance than non-water-soluble cyclodextrin when deposited onto surfaces, especially fabric.

Examples of preferred water-soluble cyclodextrin derivatives suitable for use herein are hydroxypropyl alpha-cyclodextrin, methylated alpha-cyclodextrin, methylated beta- cyclodextrin, hydroxyethyl beta-cyclodextrin, and hydroxypropyl beta-cyclodextrin.

Hydroxyalkyl cyclodextrin derivatives preferably have a degree of substitution of from about 1 to about 14, more preferably from about 1 .5 to about 7, wherein the total number of OR groups per cyclodextrin is defined as the degree of substitution. Methylated cyclodextrin derivatives typically have a degree of substitution of from about 1 to about 18, preferably from about 3 to about 16. A known methylated beta-cyclodextrin is heptakis-2,6-di-0-methyl-3-cyclodextrin, commonly known as DIMEB, in which each glucose unit has about 2 methyl groups with a degree of substitution of about 14. A preferred, more commercially available, methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin, commonly known as RAMEB, having different degrees of substitution, normally of about 12.6. RAMEB is more preferred than DIMEB, since DIMEB affects the surface activity of the preferred surfactants more than RAMEB. The preferred cyclodextrins are available, e.g., from Cerestar U.S.A., Inc. and Wacker Chemicals (U.S.A.), Inc.

In embodiments mixtures of cyclodextrins are used.

These reactive aldehydes are described in more detail in US5,676,163. Reactive aldehydes, when used, can include a combination of at least two aldehydes, with one aldehyde being selected from acyclic aliphatic aldehydes, non- terpenic aliphatic aldehydes, non-terpenic alicyclic aldehydes, terpenic aldehydes, aliphatic aldehydes substituted by an aromatic group and bifunctional aldehydes; and the second aldehyde being selected from aldehydes possessing an unsaturation alpha to the aldehyde function conjugated with an aromatic ring, and aldehydes in which the aldehyde group is on an aromatic ring. This combination of at least two aldehydes is described in more detail in WO 00/49120. As used herein, the term "reactive aldehydes" further encompasses deodourizing materials that are the reaction products of (i) an aldehyde with an alcohol, (ii) a ketone with an alcohol, or (iii) an aldehyde with the same or different aldehydes. Such deodourizing materials can be: (a) an acetal or hemiacetal produced by means of reacting an aldehyde with a carbinol; (b) a ketal or hemiketal produced by means of reacting a ketone with a carbinol; (c) a cyclic triacetal or a mixed

Flavanoids can also be used as anti-malodour agent. Flavanoids are compounds based on the C6-C3-C6 flavan skeleton. Flavanoids can be found in typical essential oils. Such oils include essential oil extracted by dry distillation from needle leaf trees and grasses such as cedar, Japanese cypress, eucalyptus, Japanese red pine, dandelion, low striped bamboo and cranesbill and can contain terpenic material such as alpha-pinene, beta- pinene, myrcene, phencone and camphene. Also included are extracts from tea leaf. Descriptions of such materials can be found in JP 02284997 and JP 04030855 incorporated herein by reference.

Metallic salts can also be used as anti-malodour agents for malodour control benefits. Examples include metal salts of fatty acids. Ricinoleic acid is a preferred fatty acid. Zinc salt is a preferred metal salt. The zinc salt of ricinoleic acid is especially preferred. A commercially available product is TEGO Sorb A30 ex Evonik. Further details of suitable metallic salts is provided below.

The intermediate zeolites are characterized by S1O2 / AIO2 molar ratios of less than about 10. Preferably the molar ratio of S1O2 / AIO2 ranges from about 2 to about 10. The intermediate zeolites can have an advantage over the "high" zeolites. The intermediate zeolites have a higher affinity for amine-type odours, they are more weight efficient for odour absorption because they have a larger surface area, and they are more moisture tolerant and retain more of their odour absorbing capacity in water than the high zeolites. A wide variety of intermediate zeolites suitable for use herein are commercially available as Valfor® CP301 -68, Valfor® 300- 63, Valfor® CP300-35, and Valfor® CP300-56, available from PQ Corporation, and the CBV100® series of zeolites from Conteka. Zeolite materials marketed under the trade name Abscents® and Smellrite®, available from The Union Carbide Corporation and UOP are also preferred. Such materials are preferred over the intermediate zeolites for control of sulfur-containing odours, e.g., thiols, mercaptans. Suitably the zeolite material has a particle size of less than about 10 microns and is present in the garment refreshing composition at a level of less than about 1 % by weight of the garment refreshing composition. Activated carbon is another suitable anti-malodour agent. Suitable carbon material is a known absorbent for organic molecules and/or for air purification purposes. Often, such carbon material is referred to as "activated" carbon or "activated" charcoal. Such carbon is available from commercial sources under such trade names as; Calgon- Type

The anti-malodour materials of the present invention may be 'free' in the composition or they may be encapsulated. Suitable encapsulating material, may comprise, but are not limited to; aminoplasts, proteins, polyurethanes, polyacrylates, polymethacrylates, polysaccharides, polyamides, polyolefins, gums, silicones, lipids, modified cellulose, polyphosphate, polystyrene, polyesters or combinations thereof.

Particularly prefered encapsulaing materials are aminoplasts, such as melamine formaldehyde or urea formaldehyde. The microcapsules of the present invention can be friable microcapsules and/or moisture activated microcapsules. By friable, it is meant that the perfume microcapsule will rupture when a force is exerted. By moisture activated, it is meant that the perfume is released in the presence of water.

To the extent any material described herein as an odour control agent might also be classified as another component described herein, for purposes of the present invention, such material shall be classified as an odour control agent.

Other Optional Ingredients Other optional ingredients may be present in the aqueous spray compositions of the present invention. For example the aqueous spray compositions may further comprise: colourants / dyes, preservatives, viscosity control agents, microcapsules comprising benefit agents, structurants / dispersants, solvents, antifoams for processing aid etc. Spray Compositions

The compositions are fabric spray compositions. By this is meant that the compositions are suitable for spraying onto a fabric. They may be sprayed by any suitable spraying device. Preferably the spray device is a manually operable spray device in the sense that the spray mechanism is manually operable to discharge a dose of said composition from the nozzle. The spray mechanism may be operated by an actuator. The actuator can be a push actuator or a pull actuator. The actuator may comprise a trigger. The spray mechanism may comprise a hand-operable pump. Optionally, said pump is one of: a positive displacement pump; a self-priming pump; a reciprocating pump. Suitable spray devices include trigger sprays, continuous / semi-continuous sprays, finger pump sprays, vibrating mesh device output sprays.

Preferably the spray device is operable without the use of a propellant. Indeed, propel lant-free spray devices are preferred. This allows the spray to maintain the integrity and purity of the product, uncontaminated with propellant and is preferably

environmentally.

Preferably the spray device is pressurised. This can improve spray duration and velocity. Preferably the spray device is pressurised by a gas chamber, separate from the reservoir containing the composition. The gas is preferably air or nitrogen. The spray device may comprise an outer container containing the composition and a pressurizing agent, wherein the composition is segregated from the pressurizing agent by containment (preferably hermetically sealed) in a flexible pouch. This which maintains complete formulation integrity so that only pure (i.e. excludes pressurising agent) composition is dispensed. Preferred systems are the so-called 'bag-in-can' (or BOV, bag-on-valve technology). Alternatively the spray device may comprise piston barrier mechanism, for example EarthSafe by Crown Holdings.

Preferably the spray device comprises a biodegradable plastic material.

The spray mechanism may further comprise an atomiser configured to break up said liquid dose into droplets and thereby facilitate creation of said fine aerosol in the form of a mist. Conveniently, said atomiser may comprise at least one of: a swirl chamber and a lateral dispersion chamber. Suitably, the atomiser functions to mix air with the aqueous fabric spray composition. The particle size of the formulation when sprayed is preferably no more than 300μη"ΐ, preferably no more than 250μη"ΐ, preferably no more than 150μη"ΐ, preferably no more than 125μη"ΐ, preferably no more than Ι ΟΟμηη. The particle size of the formulation when sprayed is preferably at least δμηι, preferably at least Ι Ομηι, preferably at least

15μη-ι, preferably at least 20μη-ι, preferably at least 30μη-ι, preferably at least

40μη"ΐ. Suitably the spray comprises droplets having an average diameter in the range of preferably 5 to 300 μηι, more preferably 10 to 250μη-ι, most preferably 15 to 150μη-ι. This size allows for homogeneous distribution and a balance between sufficient wetting of the fabric, without potential fabric damage caused by excessive dosing of certain ingredients. Droplet size may be measured on a Malvern Spraytec instrument, with the peak maximum corresponding to the average droplet size. The parameter droplet size is the volume mean diameter, D[4,3].

Suitably, following actuation, the spray has a duration in the range of at least 0.4 seconds. Preferably the spray has a duration of at least 0.8 seconds. A longer duration minimises the effort by maximising coverage per actuation of a spray device. This is an important factor for products designed to be used over the full area of

garments. Preferably the spray duration is directly linked to actuation such that the spray output continues only as long as the actuator is activated (e.g. as long as a button or trigger is pressed)

Spray reservoirs may be non-pressurised, manually or mechanically pre-pressurised devices. The above also to removable / refillable reservoirs.

According to a further aspect of the present invention, there is provided a replacement reservoir for a garment refresh product according to the above aspect(s), the replacement reservoir being pre-filled with a volume of said garment refreshing composition for replenishment of said product. A suitable "refill kit" comprises one or more reservoirs. In the case of more than one reservoir, for example two, three, four, five, or more reservoirs, the contents (aqueous fabric spray composition) of each reservoir may the same as or different from the other reservoirs. Nozzle

The spray devices of the present invention comprise a nozzle as part of the spray mechanism. The composition passes through the nozzle as it is sprayed onto clothes.

Suitably the nozzle has a discharge orifice which is configured to produce said a spray. The spray may preferably be in the form of a mist or an aerosol, more preferably a fine mist or fine aerosol. Suitably the nozzle has a discharge orifice which is configured to spray in a wide cone angle that facilitates even application of the composition to a garment. The cone angle may preferably be in the range of 55 to 80 degrees.

When microcapsules are present in the formulation, the diameter of the nozzle is preferably greater than the diameter of the microcapsules.

Dose

Conveniently, the garment refreshing composition is provided as a liquid, and said spray mechanism is operable to discharge a dose of at least 0.1 ml, preferably at least 0.2ml, more preferably at least 0.25ml, more preferably at least 0.3ml, more preferably at least 0.35ml, more preferably at least 0.35ml, more preferably at least 0.4ml, more preferably at least 0.45ml, and most preferably at least 0.5ml. Suitably the dose is no more than 2ml, preferably no more than 1 .8ml, preferably no more than 1.6ml, more preferably no more than 1 .5ml, more preferably no more than 1 .4ml, more preferably no more than 1.3ml, and most preferably no more than 1.2ml.

Suitably the dose is between 0.1 and 2ml of said liquid garment refreshing composition, preferably between 0.2 and 1.8ml, more preferably 0.25 to 1 .6ml, more preferably 0.25 to 1 .5ml, and most preferably 0.25 to 1.2ml.

These doses have been found to be particularly effective at achieving the desired garment refresh effect (for example anti-wrinkle) without unsightly and wasteful large droplet formation. Methods of Use

In one aspect of the present invention, there is provided a method of rejuvenating fabric or returning clothes to a 'just washed' state. 'Just washed' state is intended to mean the look, feel and smell of a recently laundered garment, for some garments the laundry process will include ironing (e.g. shirts). The method according to the present invention comprises the step of spraying the composition of the present invention onto a garment.

In a further aspect of the present invention, there is provided a method of inserting a crease into a garment, without the requirement of heat. The method according to the present invention comprises the steps of:

• Spraying the composition of the present invention onto a garment

• Shaping a crease into the garment

· Leaving to dry

Use of the Composition

In one aspect of the present invention, there is provided a use of the composition according to the present invention. The composition may be used to rejuvenate clothes or to return garments to a 'just washed state'.

By rejuvenate it is meant that the composition may be used to make the treated garment look and feel younger or newer. This includes restoring the garments to the look and feel of a newly purchased state, which may include: less faded colours or a thicker feel or split fibre protection or sticking down of fibrils etc.

By returning to a 'just washed state' it is meant that the composition may be used to make the garments look, feel and smell recently laundered. This includes providing the feeling of rigidity and crispness, or removing unwanted creases, removal of stretching or bagging etc. The composition of the present invention can simultaneously remove unwanted creases and provide new creases were required, e.g. pleats in a skirt, creases in smart trousers etc., without the need for ironing. In a further aspect of the present invention, there is provided a second use of the composition according to the present invention. The composition may be used to provide new creases to a garment, without the requirement of heat. Example Formulation

Method of manufacture: A vessel was charged with water and maintained at 20°C ± 5°C. To the vessel was added minors, with mixing, followed by the acrylic polymer, with mixing. The composition was neutralised if necessary. The silicone was then added, with mixing. A pre-mix was produced by blending melted non-ionic surfactant (45°C) with the free oil perfume and anti-malodour technology whilst keeping this blend at 45°C. The premix was then added to the vessel with mixing.
