LAUNDRY DETERGENT COMPOSITIONS WITH AMINO ACID BASED POLYMERS TO PROVIDE APPEARANCE AND INTEGRITY BENEFITS TO FABRICS LAUNDERED THEREWITH

Abstract: Compositions that contain from about 1 % to about 80 % by weight of surfactants selected from the group consisting of nonionic, anionic, cationic, amphoteric, or zwitterionic surfactants, or mixtures thereof; and from about 0.1 % to about 10 %, by weight of a mixture of amino acid based polymers, oligomers or copolymers of general formula (I) wherein the polymer, oligomer, or copolymer contains at least about 5 mole %, of one or more amino acids and an organic acid. These of amino acid based polymers, oligomers or copolymers can be obtained by condensing a basic amino acid, such as lysine, with an organic acid. The amino acid based polymer, oligomer or copolymer materials are useful as fabric treatment agents as they can impart fabric appearance and integrity benefits to fabrics and textiles laundered in washing solutions which contain such materials.

Description: LAUNDRY DETERGENT COMPOSITIONS WITH AMINO ACID BASED POLYMERS TO PROVIDE APPEARANCE AND INTEGRITY BENEFITS TO FABRICS LAUNDERED THEREWITH TECHNICAL FIELD The present mvention relates to compositions, m either liquid or granular form, for use m laundry applications, wherein the compositions comprise certain ammo acid based polymer, oligomer or copolymer materials which impart appearance and integrity benefits to fabrics and textiles laundered in washing solutions formed from such compositions. BACKGROUND OF THE INVENTION It is, of course, well known that alternating cycles of using and laundeπng fabrics and textiles, such as articles of worn clothing and apparel, will inevitably adversely affect the appearance and integrity of the fabric and textile items so used and laundered. Fabπcs and textiles simply wear out over time and with use. Laundeπng of fabrics and textiles is necessary to remove soils and stains which accumulate therein and thereon duπng ordinary use. However, the laundering operation itself, over many cycles, can accentuate and contribute to the deteπoration of the integrity and the appearance of such fabrics and textiles. Deterioration of fabric integπty and appearance can manifest itself in several ways. Short fibers are dislodged from woven and knit fabric/textile structures by the mechanical action of laundeπng. These dislodged fibers may form lint, fuzz or "pills" which are visible on the surface of fabrics and dimmish the appearance of newness of the fabπc. Further, repeated laundeπng of fabrics and textiles, especially with bleach-contammg laundry products, can remove dye from fabπcs and textiles and impart a faded, worn out appearance as a result of diminished color intensity, and in many cases, as a result of changes in hues or shades of color. Given the foregoing, there is clearly an ongoing need to identify matenals which could be added to laundry detergent products that would associate themselves with the fibers of the fabrics and textiles laundered using such detergent products and thereby reduce or minimize the tendency of the laundered fabπc/textiles to deteπorate in appearance. Any such detergent product additive material should, of course, be able to benefit fabπc appearance and mtegnty without unduly interfering with the ability of the laundry detergent to perform its fabπc cleaning function. The present invention is directed to the use of ammo acid based polymer, oligomer or copolymer materials in laundry applications which perform m this desired manner.

All 150 percentages are by weight unless other specified. A) Amino Acid Based Polymer, Oligomer or Copolymer Matenals The essential component of the compositions of the present mvention compπses one or more ammo acid based polymer, oligomer or copolymer.

Such compositions can be prepared by combining the essential and optional components in the requisite concentrations m any suitable order and by any conventional means. 540 Granular compositions, for example, are generally made by combining base granule ingredients, e.g., surfactants, builders, water, etc., as a slurry, and spray drying the resulting slurry to a low level of residual moisture (5-12%). The remaining dry ingredients, e.g., granules of the essential amino acid based fabπc treatment materials, can be admixed m granular powder form with the spray dried granules in a rotary mixing drum. The liquid 545 ingredients, e.g., solutions of the essential ammo acid based fabπc treatment matenals, enzymes, binders and perfumes, can be sprayed onto the resulting granules to form the finished detergent composition. Granular compositions according to the present invention can also be in "compact form", i.e. they may have a relatively higher density than conventional granular detergents, i.e. from 550 to 950 g/1. In such case, the granular 550 detergent compositions according to the present mvention will contam a lower amount of "inorganic filler salt", compared to conventional granular detergents; typical filler salts are alkaline earth metal salts of sulphates and chlorides, typically sodium sulphate; "compact" detergents typically comprise not more than 10% filler salt. Liquid detergent compositions can be prepared by admixing the essential and 555 optional ingredients thereof in any desired order to provide compositions containing components in the requisite concentrations. Liquid compositions accordmg to the present invention can also be m "compact form", in such case, the liquid detergent compositions accordmg to the present invention will contam a lower amount of water, compared to conventional liquid detergents. Addition of the ammo acid based polymer, oligomer or 560 copolymer materials to liquid detergent or other aqueous compositions of this invention may be accomplished by simply mixing into the liquid solutions the desired ammo acid based fabπc treatment materials. F) Fabric Laundering Method 565 The present invention also provides a method for laundering fabncs m a manner which imparts fabric appearance benefits provided by the ammo acid based polymer, oligomer or copolymer materials used herein. Such a method employs contacting these fabrics with an aqueous washing solution formed from an effective amount of the detergent compositions hereinbefore described or formed from the individual components of such 570 compositions Contacting of fabπcs with washing solution will generally occur under conditions of agitation although the compositions of the present mvention may also be used to form aqueous unagitated soaking solutions for fabric cleaning and treatment As discussed above, it is preferred that the washing solution have a pH of less than about 10.0, preferably it has a pH of about 9.5 and most preferably it has a pH of about 7.5. 575 Agitation is preferably provided in a washing machine for good cleaning.
