Description
DETERGENT COMPOSITIONS THAT COMPRISE STABILIZED POLYAMINOACY COMPOUNDS
FIELD OF LF > INVENTION
The present invention relates to the use of polyacidic acid containing compounds and salts thereof in detergent compositions, Nuy in particular, refers to the use of a polyamino acid, including polyaspartic acid, wherein said non-acidic polyacid is in close physical proximity to a protein to protect it against degradation.
BACKGROUND OF THE INVENTION
The polyarnino acid agents can be used in detergent compositions as builders or dispersing agents. Said description is given in EP 454126 which describes polyacids, including polyaspartic acid, co-builders or biodegradable co-builders in the formulation of detergents. Said polymers, especially those derived from aspartic acid, tartaric acid and mixtures thereof, are described as heat resistant, and pH stable, non-toxic, non-irritating and completely biodegradable. However, a problem encountered with such use is the degree of degradation of those polymers under storage and over a period. PCT / US93 / 12090 describes the use of polyaminoacetate protected against contact with a level of alkalinity that could cause degradation thereof. Said polyamino acid is provided with a coating, encapsulated or mixed in the form of an agglomerate or granulate with at least one other material which is preferably an alkaline or alkaline reaction compound. However, the research carried out by the applicant hereby revealed that this type of protection will also be degraded under storage. This is "partially" due to the enzymatic action and alkaline hydrolysis. It has now been found that a detergent composition containing a surfactant, at least one compound or polyamino acid and at least one protein wherein said polyarnino acid compound and said protein are in close physical proximity shows increased storage stability. An additional advantage to the close physical proximity of said amino acid compound and said protein is the increased stability and protection against bleaches. Another object of the present invention is to provide a detergent composition with effective removal performance of stains and dirt.
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a detergent composition comprising a detersive surfactant, at least one polyamide compound and at least one protein wherein said polyamino acid compound is in close physical proximity. For the purpose of the present invention, the term "close physical proximity" means one of the following: i) an agglomerate or extruded product in which said inoperated polyacid compound and said protein are in an intimate mixture; 11) a polyamino acid particulate material coated with one or more layers wherein at least one layer contains the protein; ni) a protein coated with one or more layers wherein at least one layer contains the polyamino acid compound. By close physical proximity it should be understood that the polyarnino acid compound and the protein are not two separate discrete particles in the detergent composition. The mixture of polyamino acid compound and protein may be present within the detergent composition in a selected form of an agglomerate, a granulated material, a tablet and mixtures thereof. A process for producing said mixture in the form of an agglomerate within a detergent composition is also provided herein.
TECHNICAL FIELD OF THE INVENTION
The present invention contemplates detergent compositions containing a dispersant having excellent storage stability against enzymes as well as against bleaches. Very particularly, it relates to a detergent composition containing a detersive surfactant, at least one polyamino acid compound and at least one protein wherein said polyamino acid compound and said protein are in close physical proximity. An essential component for the purpose of the invention is a polyamino acid compound. The term "polyacid compound" includes here not only a polyamino acid as such but also a derivative thereof, such as an amide, an ester or a salt. The polyamino acid may be a copolymer or may be a copolymer of two or more amino acids. The amino acid may be a D-amino acid, an L-amino acid or a mixture, e.g., a racemic mixture thereof. The amino acids include, for example, alanine, glycine, tyrosine, cerin and licina although glutamic, carboxyglutatic and aspartic acids are preferred. Of these, aspartic acid is particularly preferred. Normally, for the purpose of formulating a detergent composition, in a laundry detergent composition, the. polyamino acid will be used in the form of a salt thereof, preferably an alkali metal salt and most preferably the sodium salt. It will be understood that the polyamino acid compound may be constituted by a mixture of two or more compounds of the appropriate description. The molecular weight of. The polyamino acid compound can vary within wide limits, preferably, the molecular weight is from 500 to 200,000, most preferably from 2,000 to 20,000. The polyamino acid described above will comprise from 10% to 90%, preferably from 10% to 40%, and preferably from 10% to 20% by weight of the polyamino acid-protein mixture. The other essential component useful for the purpose of the invention is a protein that is in intimate contact with the polyamino acid to protect it against attack by enzymes and by bleaches. By protein is meant any of a class of polymer compounds of high molecular weight compounds of a variety of alpha-amino acids joined by peptide bonds, excluding those from the group of catalytic proteins that are produced by living cells and which are mediators and promoters of the proteins. chemical processes of life without being altered or destroyed by themselves. The proteins suitable for the purpose of the invention are microorganisms (yeasts, bacteria, molds, etc.) and that proteins extracted therein, proteins of animal origin (collagen , gelatin, glue, keratin, casein, egg albumin, etc) and proteins of vegetable origin (soy proteins, wheat gluten, etc). A preferred protein is egg white albumin. The protein described herein will comprise from 10% to 90%, preferably from 1.0% to 40% and preferably from .10% to 20% by weight of the polyamino acid-protein mixture. In accordance with the present invention, a polyamino acid compound is stabilized against degradation enough to render it acceptably stable on storage. This is done, in particular, by protecting said compound against contact with enzymes, bleaches and high alkalinity. Said stabilization can be obtained by mixing said polyaspartate with a protein as described above wherein said polyarnino acid compound and said protein are in close physical proximity (e.g., the protein is mixed to the polyamino acid in an intimate contact such that the enzymes , source of damage to said polyamino acid, preferably and selectively will attack the protein in place of the polyamino acid compound). Another advantage to said mixture is the additional protection of the polyamino acid against bleaches and high alkalinity which has also been shown to be detrimental to the stability of said polyamino acid under storage. The stabilization or protection should be such that the amount of degradation of the polyamino acid compound in the detergent composition is less than 50% during a storage period of 4 weeks under adverse conditions (32.2 ° C and 80% relative humidity) and preferably less than 50%. of 30%. Additional components can be added to the mixture.
Suitable components are those which have no deleterious effect on the properties of the mixture so that the amount of degradation of the polyamino acid remains as specified above. Suitable components that can be added to said mixture are carbonates (including bicarbonate), sulfates and aluosilicates. Another preferred embodiment suitable for the purpose of the invention comprises agglomerates formed from the mixture of polyamino acid and protein and contained in said detergent composition to increase the stabilization. Of course, other components may be included in said agglomerates. The agglomeration of the polyacid compound and the protein can be carried out using any suitable agglomeration technique and apparatus, if appropriate with compatible agglomeration aids. Said techniques, apparatuses and auxiliaries are well known in the detergent formulation art. Once the agglomerates are formed, they can be dried, if required, by conventional means. A suitable process for producing a detergent composition, containing said polyarninoacid-protein mixture in the form of an agglomerate, comprises the steps of: a) contacting said protein with the polyamino acid in the presence of water, b) stirring the resulting mixture to obtain a solid brittle agglomerate; c) grind said agglomerate to obtain a size of 250 μ to 800μ. d) incorporating the agglomerate in the detergent composition. A typical agglomerate formulation comprises: 10 to 90% polyamino acid compound rotates 10 to 40% The molten materials, i.e. the inoperated polyacid compound and the protein agglomerating agent, are fed to the agglomerator at a temperature between 35 ° C and 40 ° C. The resulting mass is then mixed for an additional 3 hours until a yellow / brown paste is formed. After stopping the mixing and the pasta is left in an oven at 35 ° C for 24 hours. The resulting solid is crushed to a fine powder in a mortar and pestle. The product is then sieved and the materials that are larger than 80 micras and less than 250 micras are removed. The stabilized polyarnino acid (e.g., the polyarninoacid-protein mixture) in accordance with the present invention is used as a dispersing agent (said term includes a clay dirt suspending agent and / or an anticaking agent). i redeposition) in solid detergent compositions (vr, granulated or particulate material) and will generally be employed thereon at a level of 0.1% to 50%, generally at least 0.4% preferably 1 to 15%, preferably from 1% to 10% and most preferably from 2.5% to 5.5% by weight of the detergent composition. The polyamino acid / protein mixture will generally have a ratio of said polyacid to said pro-eine from 9: 1 to 1: 9, preferably from 4: 1 to 1: 4 and most preferably from 2: 1 to 1: 2.

One type of oxygen-free bleaching agent of particular interest includes photoactivated bleaching agents such as sulfonated zinc phthalocyamines and /? of aluminum. See US Patent 4,033,718. If used, the detergent compositions will typically have 0.025% to 1.25%, by weight, of said bleaches, especially zinc sulfonate phthalocyte. If desired, the bleaching compounds can be catalyzed by means of a manganese compound. Such compounds are well known in the art and include, for example, the manganese-based catalysts described in US Patent 5,246,621, US Patent 5,244,594; U.S. Patent 5,194,416; Paten e North American 5,114,606; and European Patent Application Publication Nos. 549.27101, 549.272fll, 544.44002, and 544.490fll.

Peroxidase enzymes are known in the art and include, for example, perox dasa of radish, ligninase and halogenperoxidase such as chloroperoxidase and brornoperox asa. Detergent compositions containing peroxidase are described, for example, in International Application PCT UO 89/099813, assigned to Novo Indudtpes fl / S. A wide variety of enzyme materials and means for their incorporation into synthetic detergent compositions are described in U.S. Pat. 3,553,139. Finally, enzymes are described in the U.S. Patent. 4,101,457, and in the patent of E.U.fl. 4,507,219. Useful enzyme materials for liquid detergent formulations and their incorporation into such formulations are described in the U.S. Patent. 4,261,863. Enzymes for detergents can be stabilized by various techniques. Enzyme stabilization techniques are described and illustrated in the U.S. Patent. 3,600,319 and European Patent Application No. G 199 405. Enzyme stabilization systems are also described, for example, in the U.S. Pat. 3,519,570.
Enzyme Stabilizers - The enzymes employed in the present are typically stabilized by the presence of water-soluble calcium ion and / or magnesium ions in the finished compositions that provide said ions to the enzymes. (Calcium ions are in some way generally more effective than magnesium ions and are preferred in the present if only one type of cation is being used). Additional stability can be provided by the presence of several other stabilizers described in the art, especially borate species: see Severson, E.U.A. 4,537,706. The level of calcium or magnesium ions should be selected in such a way that there is always a minimum level available for the enzyme after allowing it to complex with the detergency enhancers, fatty acids, etc., in the composition. Any water-soluble calcium or magnesium salt can be used as the calcium or magnesium ion supply, including, but not limited to, calcium chloride, calcium sulfate, calcium malate, calcium maleate, calcium hydroxide, forrnia of calcium and calcium acetate and the corresponding magnesium salts. Frequently, a small amount of calcium ions, generally around * 0.05 to about 0.4 millimoles per liter, is also present in the composition due to the calcium present in the enzyme suspension and the water of the formula. In solid detergent compositions the formulation may include a sufficient amount of a supply of water-soluble calcium ions to provide such an amount in the wash solution. Alternatively, the hardness of the natural water may be sufficient. It should be understood that the aforementioned levels of calcium and / or magnesium ions are sufficient to provide enzyme stability. Additional calcium and / or magnesium ions can be added to the compositions to provide an additional measure of fat removal performance. Accordingly, as a general proposition, compositions herein typically should comprise from about 0.05% to about 2% by weight of a water soluble supply calcium or magnesium ions or both. The amount may vary, of course, depending on the amount and type of enzyme used in the composition. The compositions herein may also optionally contain, but preferably contain several additional stabilizers, especially borate type stabilizers. Typically, such stabilizers are used in the compositions at levels of from about 0.25% to about 10%, preferably from about 0.5% to about 5%, most preferably from about 0.75% to about 3% by weight of boric acid or other a borate compound capable of forming boric acid in the composition (calculated on the basis of boric acid). Boric acid is preferredalthough other compounds such as boric oxide, borax and other alkali metal borates (eg sodium orthoborate, sodium metaborate and sodium pyroborate and sodium pentaborate) are suitable. Substituted boric acids (e.g., phenyl boronic acid, butane boronic acid and p-bromophenylboronic acid) can also be used instead of boric acid.
Other ingredients A wide variety of other functional ingredients commonly used in detergent compositions can be included in the present invention. These include additional soil retardation / anti-redeposition clay agents, polyrnomeric soil release agents, dye transfer inhibiting agents, brighteners, foam suppressors and fabric softeners. The soil retention / soil anti-redeposition agents may include copolymers based on acrylic and maleic, polyethylene glycol (PEG), water-soluble ethoxylated amines and carboxymethyl cellulose (CMC). Other useful ingredients in detergent compositions can be included in the compositions herein, including other active ingredients, carriers, hydrotropes, processing aids, dyes or pigments, solvents for liquid formulations, sunscreens for bar compositions, etc. If high sputtering is desired, foaming enhancers such as Cι-C alca alkanolamines can be incorporated into the compositions, typically at levels of 1% -10%. The nonoethanol and diethanolarnins of C? O-C? < i illustrate a typical class of such foam improvers. The use of said foam enhancers with auxiliary surfactants with high foaming such as amine oxides, betaines and sultaines mentioned above is also advantageous. If desired, the soluble magnesium salts such as MgCl 2, MgSO 4 and the like, can be added at typically 0.1% -2% levels, to provide additional foaming and to increase the fat removal performance. Various detersive ingredients employed in the present compositions can be further stabilized by absorbing said ingredients on a porous hydrophobic substrate, then coating said substrate with a hydrophobic coating. Preferably, the detersive ingredient is mixed with a surfactant prior to being absorbed into the porous substrate. During use, the detersive ingredient is released from the substrate in the aqueous wash liquor, where it performs its intended detersive function. To illustrate this technique in more detail, a porous hydrophobic silica (trade name SIPERNAT DIO,
Degussa) is mixed with a proteolytic enzyme solution containing 3% -5% nonionic surfactant of ethoxylated alcohol of C13-1S (EO 7). Typically, the enzyme / surfactant solution is 2.5X the weight of the silica. The resulting powder is dispersed with agitation in silicone oil
(Various viscosities of silicone oil can be used on the scale of 500-12,500). The resulting silicone oil dispersion is emulsified or otherwise added to the final detergent matrix. By this means, ingredients such as the aforementioned photoactivators, dyes, fluorescers, fabric conditioners and hydrolyzable surfactants can be "protected" for use in detergents, including liquid laundry detergent compositions. The liquid detergent compositions may contain water and other solvents as carriers. The low molecular weight primary and secondary alcohols illustrated by methanol, ethanol, propanol and isopropanol are suitable. Unhydric alcohols are preferred for solubilizing surfactant, but polyols such as those containing 2 to 6 carbon atoms and 2 to 6 hydroxyl groups (e.g., 1,3-propanediol, ethylene glycol) can also be used. , glycerin and 1, -propanod? oL). The compositions may contain from 5% to 90%, typically from 10% to 50% of said vehicles. The detergent compositions herein will preferably be formulated such that during use in aqueous cleaning operations, the wash water has a pH of between about 6.5 and about 11, preferably between about 7.5 and 10.5. Liquid product formulations for dishwashing preferrably + have a pH between 6.8 and 9.0. Laundry products typically have a pH of 9 to 11. Techniques for controlling pH at recommended levels of use include the use of pH regulators., alkalis, acids, etc., and are well known to those skilled in the art. The bulk density of the granulated bleaching compositions (so-called granular detergent compositions) is typically at least 450 g / liter, preferably at least 600 g / liter and preferably preferably at least 650 g / liter at 1000 g / liter . The invention is illustrated in the following non-limiting examples in which all percentages are on a weight basis unless otherwise indicated.

Test protocol-stain removal
Four white cotton sheets were previously washed in a null polymer detergent matrix with a density of approximately 700 rng / liter. After 10 spots were applied to one sheet, 10 spots to the second sheet, 10 spots to the third and 10 to the fourth. From each sheet, 8 square test samples of 10cm x 10cm were cut. The series of fabric samples were subjected to a washing cycle in an automatic washing machine (Miele short wash cycle). Samples after evaluated for the removal of particulate, greasy enzymatic and bleach stains using a clarity measurement method in established. In more detail, a Miele 756 WM automatic washing machine was used, and the short cycle program at 90 ° C was selected. Water of a German hardness of 35 ° (= 3.75 moles of Ca 2+ / liter) was used. 100 g of detergent, assorted from a granule dispensing device, were used. A sample of each type of fabric was washed together with a 2.6 kg balasta load of lightly soiled sheets. Stain removal was evaluated by making LAB measurements (clarity) using an X-rite eye color spectrometer (trade name). A non-stained cotton sheet was used as a reference. A stain removal index, R, was calculated as follows: R = C (L lavida'L not washed '/ (L na lavada'L di reference)] X 100 where the differences of R less than 4% They are not significant.
