Description:

ORGANIC CATALYST WITH ENHANCED ENZYME COMPATIBILITY

FIELD OF INVENTION

This invention relates to cleaning compositions comprising organic catalysts and processes for making and using such cleaning products.

BACKGROUND OF THE INVENTION

Oxygen bleaching agents, for example hydrogen peroxide, are typically used to facilitate the removal of stains and soils from clothing and various surfaces. Unfortunately such agents are extremely temperature rate dependent. As a result, when such agents are employed in colder solutions, the bleaching action of such solutions is markedly decreased.

In an effort to resolve the aforementioned performance problem, the industry developed a class of materials known as "bleach activators". However, as such materials rapidly lose their effectiveness at solution temperatures of less than 40 0 C, new organic catalysts such as 3,4- dihydro-2-[2-(sulfooxy)decyl]isoquinolimium, inner salt were developed. In general, while such current art catalysts are effective in lower temperature water conditions, they can inactivate certain enzymes. As most laundry and cleaning compositions are formulated with enzymes, formulating cleaning products with such catalysts can be problematic.

Accordingly, there is a need for an inexpensive cleaning composition comprising an organic catalyst that can provide the combined benefits of formulation flexibility, low water temperature bleaching performance and enzyme compatibility.

SUMMARY OF THE INVENTION

The present invention relates to cleaning compositions comprising organic catalysts having enhanced enzyme compatibility, and methods of making and using same.

DETAILED DESCRIPTION OF THE INVENTION Definitions

As used herein, the term "cleaning composition" includes, unless otherwise indicated, granular or powder-form all-purpose or "heavy-duty" washing agents, especially laundry detergents; liquid, gel or paste-form all-purpose washing agents, especially the so-called heavy- duty liquid types; liquid fine-fabric detergents; hand dishwashing agents or light duty dishwashing agents, especially those of the high-foaming type; machine dishwashing agents, including the various tablet, granular, liquid and rinse-aid types for household and institutional use; liquid cleaning and disinfecting agents, including antibacterial hand-wash types, laundry

bars, mouthwashes, denture cleaners, car or carpet shampoos, bathroom cleaners; hair shampoos and hair-rinses; shower gels and foam baths and metal cleaners; as well as cleaning auxiliaries such as bleach additives and "stain-stick" or pre-treat types.

As used herein, the phrase "is independently selected from the group consisting of " means that moieties or elements that are selected from the referenced Markush group can be the same, can be different or any mixture of elements.

The test methods disclosed in the Test Methods Section of the present application must be used to determine the respective values of the parameters of Applicants' inventions.

Unless otherwise noted, all component or composition levels are in reference to the active level 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.

All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.

It should be understood that every maximum numerical limitation given throughout this specification includes every lower numerical limitation, as if such lower numerical limitations were expressly written herein. Every minimum numerical limitation given throughout this specification will include every higher numerical limitation, as if such higher numerical limitations were expressly written herein. Every numerical range given throughout this specification will include every narrower numerical range that falls within such broader numerical range, as if such narrower numerical ranges were all expressly written herein.

All documents cited are, in relevant part, incorporated herein by reference; the citation of any document is not to be construed as an admission that it is prior art with respect to the present invention.

Cleaning Compositions Comprising Organic Catalyst

Applicants have found that judicious selection of the R 1 and R 2 moieties of the organic catalyst of the present invention results in improved eii2yme compatibility. While not being bound by theory, Applicants believe this is due to favorable partitioning of the catalyst in aqueous environments as a result of the aforementioned judicious selection of the said moieties.

In one aspect of Applicants' invention, Applicants' cleaning compositions comprise an organic catalyst having an enzyme compatibility value of 70 or greater, or even 80 or greater.

In one aspect of Applicants' invention, Applicants' cleaning compositions comprise an organic catalyst having Formula 1 or Formula 2 below or mixtures thereof.

Formula 1

Formula 2 wherein: G is selected from -O-, -CH 2 O-, -(CH 2 V, an d -CH 2 -. R 1 is selected from H or Q-C 4 alkyl. Suitable Cj-C 4 alkyl moieties include, but are not limited to methyl, ethyl, iso-propyl, and tert-butyl. Each R 2 is independently selected from C 4 -Cg alkyl, benzyl, 2-methylbenzyl, 3- methylbenzyl, 4-methylbenzyl, 4-ethylbenzyl, 4-iso-propylbenzyl and 4-tert-butylbenzyl. Suitable C 4 -Cg alkyl moieties include, but are not limited to n-butyl, n-pentyl, cyclopentyl, n- hexyl, cyclohexyl, cyclohexylmethyl, n-heptyl and octyl.

In one aspect of the invention G is selected from -O- and -CH 2 -. R 1 is selected from H, methyl, ethyl, iso-propyl, and tert-butyl. Each R 2 is independently selected from C 4 -C 6 alkyl, benzyl, 2-methylbenzyl, 3-methylbenzyl, and 4-methylbenzyl.

In one aspect of the invention G is -CH 2 -, R 1 is H and each R 2 is independently selected from n-butyl, n-pentyl, n-hexyl, benzyl, 2-methylbenzyl, 3-methylbenzyl, and 4-methylbenzyl.

The balance of any aspects of the aforementioned cleaning compositions is made up of one or more adjunct materials.

Processes of Making Suitable Organic Catalysts

Suitable organic catalysts can be produced using a variety of reaction vessels and processes including batch, semi-batch and continuous processes. Suitable iminium containing versions of the catalysts (Formula 1) can be made in accordance with the general protocol described in the examples and references contained therein. The oxaziridinium ring containing version of the aforementioned catalyst may be produced by contacting an iminium containing version of said catalyst with an oxygen transfer agent such as a peroxycarboxylic acid or a peroxymonosulfuric acid. Such species can be formed in situ and used without purification.

Cleaning Compositions and Cleaning Composition Additives Comprising Applicants' Organic Catalysts

The cleaning composition of the present invention may be advantageously employed for example, in laundry applications, hard surface cleaning, automatic dishwashing applications, as well as cosmetic applications such as dentures, teeth, hair and skin. However, due to the unique advantages of both increased effectiveness in lower temperature solutions and the superior enzyme compatiblity, the organic catalysts of the present invention are ideally suited for laundry applications such as the bleaching of fabrics through the use of bleach containing detergents or laundry bleach additives. Furthermore, the organic catalysts of the present invention may be employed in both granular and liquid compositions.

The organic catalysts of the present invention may also be employed in a cleaning additive product. A cleaning additive product including the organic catalysts of the present invention is ideally suited for inclusion in a wash process when additional bleaching effectiveness is desired. Such instances may include but, are not limited to, low temperature solution cleaning application. The additive product may be, in its simplest form, Applicants' organic catalyst. Preferably, the additive could be packaged in dosage form for addition to a cleaning process where a source of peroxygen is employed and increased bleaching effectiveness is desired. Such single dosage form may comprise a pill, tablet, gelcap or other single dosage unit such as pre- measured powders or liquids. A filler or carrier material may be included to increase the volume of such composition. Suitable filler or carrier materials include, but are not limited to, various salts of sulfate, carbonate and silicate as well as talc, clay and the like. Filler or carrier materials for liquid compositions may be water or low molecular weight primary and secondary alcohols including polyols and diols. Examples of such alcohols include, but are not limited to, methanol, ethanol, propanol and isopropanol. The compositions may contain from about 5% to about 90% of such materials. Acidic fillers can be used to reduce pH. Alternatively, the cleaning additive may include an activated peroxygen source defined below or the adjunct ingredients as fully defined below.

Applicants' cleaning compositions and cleaning additives require a catalytically effective amount of Applicants' organic catalyst. The required level of such catalyst may be achieved by the addition of one or more species of Applicants' organic catalyst. As a practical matter, and not by way of limitation, the compositions and cleaning processes herein can be adjusted to provide on the order of at least 0.001 ppm, from about 0.001 ppm to about 500 ppm, from about 0.005 ppm to about 150 ppm, or even from about 0.05 ppm to about 50 ppm of Applicants' organic catalyst in the wash liquor. In order to obtain such levels in the wash liquor, typical compositions

herein may comprise from about 0.0002% to about 5%, or even from about 0.001% to about 1.5%, of organic catalyst, by weight of the cleaning compositions.

When the Applicants' organic catalyst is employed in a granular composition, it may be desirable for the Applicants' organic catalyst to be in the form of an encapsulated particle to protect the Applicants' organic catalyst from moisture and/or other components of the granular composition during storage. In addition, encapsulation is also a means of controlling the availability of the Applicants' organic catalyst during the cleaning process and may enhance the bleaching performance of the Applicants' organic catalyst. In this regard, the Applicants' organic catalyst can be encapsulated with any encapsulating material known in the art.

The encapsulating material typically encapsulates at least part, preferably all, of the Applicants' organic catalyst. Typically, the encapsulating material is water-soluble and/or water- dispersible. The encapsulating material may have a glass transition temperature (Tg) of O 0 C or higher.

The encapsulating material is preferably selected from the group consisting of carbohydrates, natural or synthetic gums, chitin and chitosan, cellulose and cellulose derivatives, silicates, phosphates, borates, polyvinyl alcohol, polyethylene glycol, paraffin waxes and combinations thereof. Preferably the encapsulating material is a carbohydrate, typically selected from the group consisting of monosaccharides, oligosaccharides, polysaccharides, and combinations thereof. Most preferably, the encapsulating material is a starch. Preferred starches are described in EP 0 922 499; US 4,977,252; US 5,354,559 and US 5,935,826.

The encapsulating material may be a microsphere made from plastic such as thermoplastics, acrylonitrile, methacrylonitrile, polyacrylonitrile, polymethacrylonitrile and mixtures thereof; commercially available microspheres that can be used are those supplied by Expancel of Stockviksverken, Sweden under the trademark Expancel®, and those supplied by PQ Corp. of Valley Forge, Pennsylvania USA under the tradename PM 6545, PM 6550, PM 7220, PM 7228, Extendospheres®, Luxsil®, Q-cel® and Sphericel®.

The cleaning compositions herein will preferably be formulated such that, during use in aqueous cleaning operations, the wash water will have a pH of between about 6.5 and about 11, or even about 7.5 and 10.5. Liquid dishwashing product formulations may have a pH between about 6.8 and about 9.0. Laundry products typically have a pH of from about 9 to about 11. Techniques for controlling pH at recommended usage levels include the use of buffers, alkalis, acids, etc., and are well known to those skilled in the art.

Step 1. Preparation of α,α-dibutyl-benzeneacetonitrile (2): To a flame dried 500 mL three neck round bottomed flask, equipped with a dry argon inlet, magnetic stir bar, and thermometer, is added benzyl cyanide ((1), 5.0 gm.; 0.043 mol) and tetrahydrofuran (100 mL). To the reaction is slowly added sodium hydride (60% in oil) (7.2 gm, 0.1075 mol) over one hour. Once addition is complete the reaction is stirred at room temperature for 1 hour. To the reaction is added benzyl bromide (18.4 gm; 0.043 mol) and the reaction is stirred at 50 0 C for 18 hours. The reaction is evaporated to dryness, residue dissolved in toluene and washed with IN HCl. Organic phase is dried with Na 2 SO 4 , filtered and evaporated to yield α,α-dibutyl-benzeneacetonitrile (2), wt= 7.7 gm (65%).

Step 2. Preparation of l-amino-2,2,dibutyI-2-phenylethane (3): α,α-Dibutyl-benzeneacetonitrile ((2), 7.0 gm; 0.0237 mol) is dissolved in borane-THF complex (1.1 equiv.) at room temperature for 18 hours. Once reaction is complete, ethanol (50 mL) is added, and the reaction is evaporated to dryness. Once dry, the residue is suspended in 100 mL IM HCl, and the suspension is evaporated to dryness on a rotory evaporator. This procedure is repeated three times. After the final evaporation, the white residue is dissolved in IM NaOH (100 mL), and extracted with diethyl ether (2 x 150 mL). The extracts are combined, dried with filtered and evaporated to dryness to yield l-amino-2,2,dibutyl-2-phenylethane (3), wt= 6.4 gm (90%).

To the addition funnel is added formic acid (5.0 gm). The formic acid is added slowly to the stirring reaction solution over 60 minutes and solids form. Once addition is complete the reaction is brought to reflux and water removed via a Dean Stark trap. Once the reaction is complete, the toluene is removed to yield N-formyl-β,β-dibutyl-β -phenethylamine (4), wt= 4.9 gm (90%). The formamide (4) is then contacted with polyphosphoric acid (30 gm)/phosphorous pentoxide (6 gm), using standard Bischler/Napieralski conditions, at 170 0 C for 18 hours. The reaction is then neutralized with aqueous NaOH, keeping the temperature between 60 -80 0 C. Once neutral, the product is extracted with toluene to yield 3,4-dihydro-4,4-dibenzyl-isoquinoline (5). The product can be further purified on silica gel.

Step 4. Preparation of 3,4-dihydro-4,4-dibutyl-2-(3-sulfopropyl)isoquinolinium, internal salt (6): To a flame dried 100 mL round bottomed flask is added 3,4-dihydro-4,4-dibenzyl-isoquinoline ((5)3.0 gm; 0.010 mol) and acetonitrile (25 mL). The solution is stirred at room temperature under argon and to the solution is added l,2-oxathiolane-2,2-dioxide (1.34 gm; 0.011 mol). The reaction is warmed to 50 0 C and stirred for 18 hours. The reaction is cooled to room temperature, and allowed to stand at room temperature over night.
