Definitions
- This invention relates to laundry detergent compositions having enhanced whitening and stain removal benefits. More particularly, this invention relates to laundry detergent compositions containing among other components, a combination of an endo- cellulase enzyme, a protease enzyme and polyacrylate polymer, and which is particularly effective for providing enhanced whitening and stain removal benefits to soiled fabrics.
- Cellulase enzymes and protease enzymes are known components of laundry detergent compositions which chemically decompose stains and provide improved cleaning of washed fabrics.
- U.S. Patent 5,858,948 describes laundry detergent compositions wherein the combination of a protease enzyme with a modified polyamine cotton soil release agent provides improved cleaning and soil release benefits.
- a laundry detergent composition which provides enhanced whitening and stain removal benefits to washed laundry comprising:
- laundering of stained or soiled fabrics is effected by washing the fabrics to be laundered in an aqueous wash solution containing an effective amount of the above-described laundry detergent composition.
- the present invention is predicated on the discovery that the combination of protease enzyme, endo-cellulase enzyme and acrylic acid-based polymer or copolymer in detergent composition in accordance with the invention provides surprisingly effective stain removal and whitening significantly better than would be expected by the levels of enzyme in the composition itself.
- protease enzyme is provided in a detergent composition at a level greater than about .06 Anson units of activity per gram of composition
- the resultant combination of protease and endo- cellulase enzyme provides a synergistic whitening effect in the presence of an acrylate- based polymer such as sodium polyacrylate.
- One Novo Protease Units is the amount of enzyme which hydrolyzes casein at such a rate that the initial rate of formation of peptides/minute corresponds to 1 micromole of glycine/minute.
- 1 KNPU Kelo NPU
- 1000 NPU 1000 NPU.
- 3 KNPU are approximately equal to 1
- Anson unit (AU).
- KNPU Anson unit
- One KNPU corresponds to about 80,000 Alkaline Delft Units or about 80 Properase Units (PU) or about 2.5 Genencor Subtilisin Units (GSU).
- cellulase enzyme refers to those enzyme compositions derived from fungal sources or microorganisms genetically modified so as to incorporate and express all or part of the cellulase genes obtained from a fungal source ("fungal cellulases") or bacterial sources of cellulase. Fungi and bacteria capable of providing cellulase enzymes which are useful in detergent compositions are well documented in the literature.
- Cellulases are known to be comprised of several enzyme classifications having different substrate specificity, enzymatic action patterns and the like.
- cellulases can contain cellulase classifications which include endoglucanases and exo- cellobiohydrolases.
- endo-cellulase refers to those cellulase enzymes and enzyme-containing compositions which comprise at least 50% endoglucanase type components among other cellulose degrading cellulase components.
- cellulases generally have their optimum activity in the acidic or neutral pH range although some fungal cellulases are known to possess significant activity under neutral and slightly alkaline conditions.
- Optimum activity of an enzyme is ordinarily a function of both pH and temperature.
- the amount of endo-cellulose enzyme in the laundry detergent composition is from about 0.5 to about 100 CMC units per gram of composition.
- Preferred activity levels range from about 1 to 25 CMC units per gram, and most preferably from about 1 to 10 CMC units per gram.
- protease enzymes used in the compositions of the invention are present at levels sufficient to provide at least about 0.030 to about 3.0 KNPU of activity per gram of composition, preferably from about 0.06 to about 0.5 KNPU per gram, and most preferably from about 0.06 to about 0.1 KNPU per gram of composition.
- Protease enzyme may be of animal, vegetable or microorganism origin. Suitable proteolytic include the many species known to be adapted for use in detergent compositions.
- Especially useful commercial enzyme preparations for the present invention include Alcalase®, Esperase® and Savinase ® sold by Novo Industries, Denmark, and Maxatase ® , Maxacal ® , Purafect ® , and Properase sold by Genecor International.
- any suitable nonionic detergent compound may be used as a surfactant in the present compositions, with many members thereof being described in the various annual issues of Detergents and Emulsifiers, by John W. McCutcheon. Such volumes give chemical formulas and trade names for commercial nonionic detergents marketed in the United States, and substantially all of such detergents can be employed in the present compositions. However, it is highly preferred that such nonionic detergent be a condensation product of ethylene oxide and higher fatty alcohol (although instead of the higher fatty alcohol, higher fatty acids and alkyl [octyl, nonyl and isooctyl] phenols may also be employed).
- the higher fatty moieties, such as the alkyls, of such alcohols and resulting condensation products, will normally be linear, of 10 to 18 carbon atoms, preferably of 10 to 16 carbon atoms, more preferably of 12 to 15 carbon atoms and sometimes most preferably of 12 to 14 carbon atoms. Because such fatty alcohols are normally available commercially only as mixtures, the numbers of carbon atoms given are necessarily averages but in some instances the ranges of numbers of carbon atoms may be actual limits for the alcohols employed and for the corresponding alkyls.
- the ethylene oxide (EtO) contents of the nonionic detergents will normally be in the range of 3 to 15 moles of EtO per mole of higher fatty alcohol, although as much as 20 moles of EtO may be present.
- EtO content will be 3 to 10 moles and more preferably it will be 6 to 7 moles, e.g., 6.5 or 7 moles per mole of higher fatty alcohol (and per mole of nonionic detergent).
- the polyethoxylate limits given are also limits on the averages of the numbers of EtO groups present in the condensation product.
- suitable nonionic detergents include those sold by Shell Chemical Company under the trademark Neodol®, including Neodol 25-7, Neodol 23-6.5 and Neodol 25-3.
- alkylpolyglycoside and alkylpolysaccharide surfactants, which are well known and extensively described in the art.
- Preferred alkyl polysaccharides for use herein are alkyl polyglucosides having the formula
- Z is derived from glucose
- R is a hydrophobic group selected from the group consisting of alkyl, alkylphenyl, hydroxyalkylphenyl, and mixtures thereof in which said alkyl groups contain from about 10 to 18, preferably from about 12 to about 14 carbon atoms; n is 2 or 3 preferably, 2; r is from 0 to 10, preferably 0; and x is from 1.5 to 8, preferably from 1.5 to 4, most preferably from 1.6 to 2.7.
- a long chain alcohol R 2 OH where R 2 is an alkyl group of about C 1 0 to C ⁇ s
- a short chain alcohol RjOH wherein Rj is an alkyl having from 1 to 6 carbon atoms
- the short chain alkylglucoside content of the final alkyl polyglucoside material should be less than 50%, preferably less than 10%, more preferably less than about 5%, most preferably 0% of the alkyl polyglucoside.
- the amount of unreacted alcohol (the free fatty alcohol content) in the desired alkyl polysaccharide surfactant is preferably less than about 2%, more preferably less than about 0.5% by weight of the total of the alkyl polysaccharide. For some uses it is desirable to have the alkyl monosaccharide content less than about 10%.
- APG glycoside surfactant is Glucopon 625 CSUP glycoside manufactured by the Henkel Corporation of Ambler, PA.
- Glucopon 625 CSUP is a nonionic alkyl polyglycoside characterized by the formula:
- anionic surface active agents useful in the present invention are those surface active compounds which contain an organic hydrophobic group containing from about 8 to 26 carbon atoms and preferably from about 10 to 18 carbon atoms in their molecular structure and at least one water-solubilizing group selected from the group of sulfonate, sulfate, carboxylate, phosphorate and phosphate so as to form a water-soluble detergent.
- sulfate or sulfonate detergents are paraffin sulfonates containing from about 10 to 20 carbon atoms, and preferably from about 15 to 20 carbon atoms.
- the primary paraffin sulfonates are made by reacting long chain alpha olefins and bisulfites.
- the most highly preferred water-soluble anionic detergent compounds are the ammonium and substituted ammonium (such as mono, di and tri ethanolamine), alkali metal (such as, sodium and potassium) and alkaline earth metal (such as, calcium and magnesium) salts of the higher alkyl benzene sulfonates, olefine sulfonates and higher alkyl sulfates.
- alkali metal such as, sodium and potassium
- alkaline earth metal such as, calcium and magnesium
- the most preferred are the sodium linear alkyl benzene sulfonates (LABS), and especially those wherein the alkyl group is a straight chain alkyl radical of 12 or 13 carbon atoms.
- Builder materials may advantageously be included in the present compositions and may comprise any suitable water soluble or water insoluble builder, either inorganic or organic, providing that it is useful as a builder for the particular nonionic or anionic detergent compounds that may be employed.
- Such builders are well known to those of skill in the detergent art and include: alkali metal phosphates, such as alkali metal polyphosphates and pyrophosphates, including alkali metal tripolyphosphates; alkali metal silicates, including those of Na O:SiO ratio in the range of 1:1.6 to 1:3.0, preferably 1:2.0 to 1:2.8, and more preferably 1:2.35 or 1:2.4; alkali metal carbonates; alkali metal bicarbonates; alkali metal sesquicarbonates (which may be considered to be a mixture of alkali metal carbonates and alkali metal bicarbonates); alkali metal borates, e.g., borax; alkali metal citrates; alkali metal gluconates; al
- the builders will be sodium salts and will also be inorganic.
- a highly preferred non-phosphate mixed water soluble and water insoluble builder composition comprises carbonate, bicarbonate and zeolite builders. Phosphate -containing builder systems will usually be based on alkali metal (sodium) tripolyphosphate and silicate builders, with such silicate being in relatively minor proportion.
- suitable adjuvants are enzymes supplementary to the lipase which is an integral component of the present compositions to further promote cleaning of certain hard to remove stains from laundry or hard surfaces.
- enzymes the proteolytic and amylolytic enzymes are most useful to supplement the lipase.
- foaming agents such as lauric myristic diethanolamide, when foam is desired, and anti-foams, when desired, such as dimethyl silicone fluids.
- composition J was a composition of the invention containing polyacrylate, cellulase, and a high level of protease.
- Compositions G and K contained only components of the invention, with G having polyacrylate and cellulase, but a level of protease outside the invention, and K having protease and cellulase.
- Example E was a control composition with conventional levels of protease and other active ingredients.
- the protease enzyme is Savinase 6T from Novo Nor isk Corp.
- the activity corresponding to 0.42 wt. % as in Composition E is 0.0252 KNPU per gram of composition.
