Description

DETERGENT COMPOSITIONS FOR LAUNDRY WITH CERTAIN DOWNLOADED COLORING CONSERVATION POLYMERS CANONICALLY FIELD OF THE INVENTION The present invention relates to compositions, either in liquid form or in granule form, for use in laundry applications, in which the compositions comprise certain dye preservation polymers having a positive net charge. Compositions comprising the dye preservation polymers of this invention impart appearance and integrity benefits to fabrics and textiles washed in wash solutions formed from said compositions.

BACKGROUND OF THE INVENTION It is well known, of course, that alternating cycles of use and washing of fabrics and textiles, such as garment items and used clothing accessories, will inevitably adversely affect the appearance and integrity of the fabric and the textile materials used. and washed in this way. Fabrics and textiles simply wear out over time and with use. The washing of fabrics and textiles is necessary to remove dirt and stains that accumulate in them during ordinary use. However, the washing operation itself, after many cycles, can accentuate and contribute to the deterioration of the integrity and appearance of said fabrics and textiles. The deterioration of the appearance and integrity of the fabrics can manifest itself in several ways. The short fibers are detached from spun and woven structures of fabrics / textiles by the mechanical action of washing. These loose fibers can form lint, lint or "balls" that are visible on the fabric surfaces and diminish the appearance of new product of the fabric. In addition, repeated washing of fabrics and textiles, especially laundry products containing bleach, can remove dye from fabrics and textiles and impart a worn, worn appearance as a result of decreased color intensity, and in many cases, as a result of changes in shades or shades of color. Given the above, there is clearly a growing need to identify materials that could be added to laundry products that would associate themselves with the fibers of the fabrics and textiles that are washed using said products and thus reduce or minimize the tendency of washed fabrics / textiles to deteriorate in appearance. Any such detergent additive materials should, of course, be able to benefit the appearance and integrity of the fabrics without unduly interfering with the stability of the laundry product to perform its designed function. The present invention is directed to the use of dye preservation polymers in laundry applications that function in this desired manner.

BRIEF DESCRIPTION OF THE INVENTION The present invention satisfies the aforementioned need because it has been discovered with surprise that the fabric to be treated, and subsequently re-treated with the compositions of the present invention, will resist fading and loss of color regardless of the circumstances, inter alia, to mechanical use and abrasion.

In addition to the surfactant and dye preservation polymer of this invention, the laundry detergent compositions herein comprise from 0.01% to 80% by weight of an organic or inorganic builder and other conventional laundry detergent products. In this aspect of the method, the present invention relates to the washing or treatment of fabrics and textile materials in aqueous solutions for washing, rinsing, or treatment formed from effective amounts of any of the detergent compositions, fabric softening compositions, or treatments of aqueous solutions as described herein, or formed from the individual components of said compositions. The washing of fabrics and textiles in said washing, rinsing and / or treatment solutions, followed by drying, imparts fabric appearance benefits to articles of fabrics and textiles treated in this manner. Such benefits may include improved overall appearance, ball / lint reduction, anti-fading, improved abrasion resistance, and / or improved softness. It has been surprisingly determined that the dye preservation polymers of this invention impart fabric appearance and integrity benefits that are larger than the benefits that are achieved by a corresponding amount of any component alone. These and other objects, features and advantages will become apparent to those skilled in the art from the reading of the following detailed description and the appended claims. All percentages, ratios and proportions herein are by weight, unless otherwise specified. All temperatures are in degrees Celsius (° C) unless otherwise specified. All the cited documents are included, a considerable part, in the present by way of reference.

DETAILED DESCRIPTION OF THE INVENTION As noted, when the fabrics or textiles are washed in solutions comprising the dye preservation polymers of the present invention the appearance and integrity of the fabrics are improved. The dye preservation polymers can be added to wash solutions by incorporating them into a detergent composition, a fabric softener, or by adding them separately to the washing solution. The dye preservation polymers are described herein primarily as liquid or granular detergent additives but the present invention does not mean that it is limited in that way. The dye preservation polymers, the detergent compositions, the optional ingredients for said compositions and methods for using said compositions are described in detail below. All percentages are by weight unless otherwise specified.

Dye preservation polymers The compositions and systems of the present invention comprise from about 0.1%, preferably about 1%, most preferably about 2%, most preferably from 3% to about 10%, preferably to 7%, most preferably at 5% by weight, of a polymer, copolymer or its mixture, in which the polymer or copolymer comprises at least one cationically charged unit, inter alia, quaternary ammonium portion or unit that can form a cationic charge in situ, inter alia, primary amine portion. Put another way, the oligomer, polymer, or copolymer resulting from the monomer units described hereunder must have a net cationic charge. The load can be distributed among any of the units described herein. The dye preservation polymers of this invention can be used in any fabric washing process and provide certain appearance benefits to fabrics washed in those processes. Said fabrics appearance benefits may include, for example, improved overall appearance of the washed fabrics, reduction of ball and lint formation, protection against color wear, improved abrasion resistance, etc. The colorant preservation polymers that are used in the compositions and methods herein can provide such fabric appearance benefits when included in washing or rinsing products.

Particular preference is given to carbonate, bicarbonate, sesquicarbonate, tetraborate, sodium and potassium decahydrate, and silicates having a weight ratio of SiO to alkali metal oxide of 0.5 to 4.0, preferably 1.0 to 2.4. Aluminosilicates including zeolites are also preferred. Such materials and their use as detergency builders are more fully described in Corkill et al, U.S. Pat. No. 4,605,509, the description of which is incorporated herein by reference. They are also described in the patent of E.U.A. No. 4,605,509 the layered crystalline silicates which are suitable for use in the detergent compositions of this invention.

Optional Detergent Ingredients In addition to the surfactants, builders and dye preservation polymers of the detergent compositions of the present invention, any number of optional additional ingredients may also be included. These include conventional detergent composition components such as enzymes and enzyme stabilizing agents, foaming impellers or suds suppressors, anti-oxidation and anti-corrosion agents, bleaching agents, soil suspending agents, soil release agents, germicides, surface release agents pH adjustment, alkalinity sources not detergent builders, chelating agents, organic and inorganic fillers, solvents, hydrotropes, optical brighteners, dyes and perfumes. Agents for pH adjustment may be necessary in certain applications where the pH of the wash solution is greater than 10.0 because the fabric integrity benefits of the defined compositions begin to decrease at a higher pH. Hence, if the wash solution is larger than 10.0 after the addition of the dye preservation polymers of the present invention, a pH adjuster should be used to reduce the pH of the wash solution to below 10.0, preferably at a pH below 9.5, and more preferably below 7.5. Suitable pH adjusters will be known to those skilled in the art. A preferred optional ingredient for incorporation into the detergent compositions herein comprises a bleaching agent, for example, a peroxygen bleach. Said peroxygen bleaching agents may be organic or inorganic in nature. Inorganic peroxygen bleaching agents are often used in combination with a bleach activator. Useful organic peroxygen bleaching agents include percarboxylic acid bleaching agents and salts thereof. Suitable examples of this class of agents include magnesium monoperoxyphthalate hexahydrate, the magnesium salt of metachloroperbenzoic acid, 4-nonylamino-4-oxoperoxybutyric acid and diperoxydecanedioic acid. Said bleaching agents are described in the patent of E.U.A. 4,483,781, Hartman, issued November 20, 1984; European Patent Application EP-A-133,354, Banks et al, published February 20, 1985; and the US patent. 4,412,934, Chung et al, issued November 1, 1983. Preferred bleaching agents also include 6-nonylamino-6-oxoperoxycaproic acid (NAPAA) as described in U.S. Pat. 4,634,551, issued on January 6, 1987 to Bums et al. The inorganic peroxygen bleaching agents can also be used, generally in the form of a particulate form, in the detergent compositions herein. Inorganic bleaching agents are in fact preferred. Such inorganic peroxygen compounds include alkali metal materials of perborate and percarbonate. For example, sodium perborate (for example mono- or tetrahydrate) can be used. Suitable inorganic bleaching agents may also include sodium or potassium carbonate peroxyhydrate and equivalent "percarbonate" bleaches, sodium pyrophosphate peroxyhydrate, urea peroxyhydrate, and sodium peroxide. Persulfate bleach (for example OXONE, commercially manufactured by DuPont) can also be used. Inorganic peroxygen bleaches will often be coated with silicate, borate, sulfate or water-soluble surfactants. For example, coated percarbonate particles are available from various commercial sources such as FMC, Solvay Interox, Tokai Denka and Degussa. Inorganic peroxygen bleaching agents, for example, perborates, percarbonates, etc., are preferably combined with bleach activators, which leads to in situ production in aqueous solution (i.e. while using the present compositions for washing / bleaching fabrics) of the peroxy acid corresponding to the bleach activator. Several non-limiting examples of activators are described in U.S. Patent No. 4,915,854, issued April 10, 10, 1990 to Mao et al, and the U.S. patent. 4,412,934 issued November 1, 1983 to Chung et al. The nonanoyloxybenzenesulfonates (NOBS) and tetraacetyl ethylenediamine (TAED) are typical and preferred activators. Mixtures thereof can also be used. See also the patent of E.U.A. 4,634,551 to which reference is made above for other typical bleaches and activators useful herein. Other useful amido-derived bleach activators are those of the formulas: R1N (R5) C (O) RC (O) L or R1C (0) N (R5) RC (O) L wherein R1 is an alkyl group which contains from about 6 to about 12 carbon atoms, R 2 is an alkylene containing from about 1 to about 6 carbon atoms, R 5 is H or alkyl, aryl, or alkaryl containing from about 1 to about 10 carbon atoms. carbon, and L is any suitable residual group. A residual group is any group that is displaced from the bleach activator as a consequence of the nucleophilic attack on the bleach activator by the perhydrolysis anion. A preferred residual group is phenol sulfate. Preferred examples of bleach activators of the above formulas include (6-octanamido-caproyl) oxybenzenesulfonate, (6-nonanamidocaproyl) oxybenzenesulfonate, (6-decanamido-caproxy) oxybenzenesulfonate and mixtures thereof as described in the patent of US Pat. 4,634,551 to which reference is made above.

Another class of useful bleach activators comprises the benzoxazine type activators that are described by Hodge et al in the U.S. patent. 4,966,723, issued October 30, 1990, incorporated herein by reference. See also the patent of E.U.A. 4,545,784, issued to Sanderson, October 8, 1985, incorporated herein by reference, which discloses acylcaprolactams, including benzoyl caprolactam, adsorbed to sodium perborate. If used, the peroxygen bleaching agent will generally comprise from 2% to 30% by weight of the detergent compositions herein. More preferably, the peroxygen bleaching agent will comprise from 2% to 20% by weight of the compositions. More preferably, the peroxygen bleaching agent will be present to the extent of 3% to 15% by weight of the present compositions. If used, the bleach activators may comprise from 2% to 10% by weight of the detergent compositions present. Frequently, the activators are used so that the molar ratio of bleaching agent to activator is in the range of 1: 1 to 10: 1, more preferably 1.5: 1 to 5: 1. Additional suitable bleach activators and bleach activators are described in one or more of the co-pending PCT applications listed in Table A and incorporated herein by reference. Another highly preferred optional ingredient in the detergent compositions herein is a detersive enzyme component. The enzymes can be included in the detergent compositions present for a variety of purposes, including spot removal of protein-based substrates, based on carbohydrate, or based on triglycerides, for the prevention of transfer of refugee dye in fabric washing, and for restoration of fabrics. Suitable enzymes include proteases, amylases, lipases, cellulases, peroxidases, and mixtures thereof of any suitable origin, such as plant, animal, bacterial, fungal and yeast origin. Preferred selections are influenced by factors such as pH activity and / or stability, optimal thermostability, and stability to detergent actives, builders and the like. In this regard, bacterial or fungal enzymes, such as bacterial amylases and proteases, and fungal cellulases are preferred. "Detersive enzyme", as used herein, means any enzyme that has a cleaning, dirt removal or otherwise beneficial effect in a laundry detergent composition. Preferred enzymes for laundry purposes include, but are not limited to, proteases, cellulases, lipases, amylases and peroxidases. Enzymes are normally incorporated in detergent compositions at levels sufficient to provide an "effective amount for cleaning". The term "effective amount for cleaning" refers to any amount capable of producing a cleaning, stain removal, dirt removing, bleaching, deodorizing, or freshness improving effect on substrates such as fabrics. In practical terms for current commercial preparations, typical amounts are up to 5 mg by weight, more typically from 0.01 mg to 3 mg of active enzyme per gram of detergent composition. Established otherwise, the present compositions will typically contain from 0.001% to 5%, preferably 0.01% -1% by weight of a commercial enzyme preparation. Protease enzymes are normally present in such commercial preparations at levels sufficient to provide 0.005 to 0.1 Anson units (AU) of activity per gram of composition. Higher active levels may be desirable in highly concentrated detergent formulations. Cellulases that can be used herein include those described in the U.S.A. No. 4,435,307, Barbesgoard et al, March 6, 1984, and GB-A-2,075,028; GB-A-2,095,275 and DE-OS-2,247,832. CAREZYME® and CELLUZYME® (Novo) are especially useful. See also WO 9117243 to Novo. The enzyme-containing compositions herein may also optionally comprise from about 0.001% to about 10%, preferably from about 0.005% to about 8%, more preferably from 0.01% to 6%, by weight of an enzyme stabilizing system . The enzyme stabilizing system can be any stabilizing system which is compatible with the detersive enzyme. Such a system can be provided inherently by other formulation actives, or it can be added separately, for example, by the formulator or by a manufacturer of ready-to-use detergent enzymes. Said stabilizing systems can, for example, comprise calcium ions, boric acid, propylene glycol, short chain carboxylic acids, boronic acids, and mixtures thereof, and are designed to face different stabilization problems depending on the type and physical form of the detergent composition.

Preparation of the detergent composition The detergent compositions according to the present invention may be in liquid, paste or granular form. Said compositions can be prepared by combining the essential and optional components in the required concentrations in any suitable order and by any conventional means. The aforementioned description of uses for the dye preservation polymers that are defined herein is intended to be illustrative and other uses will be apparent to those skilled in the art and are designed to be within the scope of the present invention. For example, granular compositions are generally made by combining base granule ingredients, for example, surfactants, builders, water, etc., as a suspension, and spray drying the resulting suspension at a low level of residual moisture ( 5-12%). The remaining dry ingredients, for example, granules of the essential dye preservation polymers, can be mixed in the form of granular powder with the spray-dried granules in a rotating mixing drum. Liquid ingredients, for example, solutions of the essential coloring preservative polymers, enzymes, binders and perfumes, can be sprayed onto the resulting granules to form the finished detergent composition. The granular compositions according to the present invention can also be in "compact form", that is, they can have a relatively higher density than conventional granular detergents, ie from 550 to 950 g / l. In such a case, the granular detergent compositions according to the present invention will contain a lower amount of "inorganic filler salt", in comparison to conventional granular detergents; typical filler salts are alkaline earth metal salts of sulfates and chlorides, typically sodium sulfate; "Compact" detergents typically comprise no more than 10% filler salt. Liquid detergent compositions can be prepared by mixing the essential and optional ingredients thereof in any desired order to provide compositions containing components in the required concentrations. The liquid compositions according to the present invention can be in "compact form", in such case, the liquid detergent compositions according to the present invention will contain a lower amount of water, compared to conventional liquid detergents. The addition of the dye preservation polymers to the liquid detergent or other aqueous compositions of this invention can be achieved simply by mixing the desired dye preservation polymers in the liquid solutions.

Fabric Washing Method The present invention also provides a method for washing fabrics in a manner that imparts appearance benefits of fabrics provided by the colorant preservation polymers that are used herein. Said method uses contacting said fabrics with an aqueous wash solution formed from an effective amount of the detergent compositions herein described above or formed from the individual components of said compositions. The contact of the fabrics with the washing solution will generally occur under stirring conditions although the compositions of the present invention can also be used to form aqueous solutions for soaking without stirring for fabric cleaning and treatment. As discussed above, it is preferred that the wash solution has a pH of less than 10.0, preferably has a pH of about 9.5, and more preferably has a pH of about 7.5. The agitation is preferably provided in a washing machine for good cleaning. The washing is preferably followed by drying the wet cloth in a conventional cloth dryer. An effective amount of a high density liquid or granular detergent composition in the aqueous wash solution in the washing machine is preferably from 500 to 7000 ppm, more preferably from 1000 to 3000 ppm.
