The present invention relates to detergent compositions, including laundry, dishwashing and household cleaning compositions comprising an enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils.
The overall performance of a detergent product for use in washing or cleaning method such as laundry, dishwashing, household cleaning, is judged by a number of factors, including the ability to remove body soils, greasy/oily soils and the ability to prevent redeposition of the soils or the breakdown products of the soils on the articles in the wash.
The complex nature of everyday "body" soils typically found on pillow cases, T-shirts, collars and socks, provides a thorough cleaning challenge for detergents. These soils are difficult to remove completely and often residues build up on fabric leading to dinginess and yellowing. Greasy/oily soils and stains represent also a well-known cleaning challenge often met by the inclusion of a lipolytic enzyme in the detergent compositions.
It is therefore an object of the present invention to provide detergent compositions, including laundry, dishwashing and household cleaning compositions, which provide cleaning performance on body soils and/or oily/greasy soils and stains.
The above objective has been met by formulating detergent compositions comprising an enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils. These enzymes enhance the removal of such stains/soils by directly reacting with the saturated fatty acid components of the stains thereby increasing the water-solubility of said fatty acid component and resulting in an overall increase in stains/soils removal.
It has been further found that the overall performance of the detergent compositions of the present invention is optimised by the addition of another detergent enzyme, especially a lipolytic enzyme and/or a polymeric soil release agent.
According to the present invention, prefered enzymes that increase the water-solubility of saturated fatty acid-containing stains/soils are e.g. the acid-thiol ligase, desaturase and gluthathione S-transferase enzymes.
Acid-thiol ligases are commonly used in the determination of free fatty acids and of lipase activity (JP1020099; EP 273 647; U.S. Pat. No. 4,491,631; JP56158097; U.S. Pat. No. 4,360,591; JP60233560) and in pharmaceuticals products (U.S. Pat. No. 4,822,776). Desaturase enzymes are mainly described in transgenic plant production such as in the most recent WO96/21022, WO96/13591, U.S. Pat. No. 5,430,134, WO95/18222, WO94/18337, EP 644 263 as well as for the production of seed oil containing altered levels of saturated--unsaturated fatty acids such as in the most recent U.S. Pat. No. 5,443,974; WO94/10189; EP 561 569; WO91/18985; WO91/13972. The glutathion S-transferase enzyme is used in plant resistance to herbicide (WO97/11189 and DE 19 501 840) or in medical treatment and/or diagnostic such as in the most recent J09 0330521, J09 021 806, RU2 063 044, WO 96/40739, WO96/40205, J08 245 424, WO96/31779, J08 059 501, WO96/02674.
However, the use of an enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils has never been previously suggested in detergent compositions, nor the benefits resulting therefrom when used in detergent compositions, have been recognised.
The present invention relates to detergent compositions, including laundry, dishwashing and household cleaning compositions, comprising an enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils, thereby providing cleaning performance on body soils and/or oily/greasy soils and stains.
In another embodiment, the present invention relates to detergent compositions further comprising another detergent enzyme, especially a lipolytic enzyme and/or a polymeric soil release agent.
Enzymes That Increase the Water-Solubility of Saturated Fatty Acid-Containing Stains/Soils
An essential element of the detergent composition of the present invention is an enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils.
By the term "an enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils" it is meant any enzyme which acts directly on saturated fatty acids and achieves 20%, preferably 30%, more preferably 35% of fatty acid removal. The % of fatty acid removal is measured by the following method:
1. Soil cotton swatches with fatty acid stains being melted butter, palmitic and/or stearic fatty acid stains.
2. Pre-treatment/wash in Tris Buffer pH 7 with 0.05% pure enzyme by weight of total composition of the enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils and with its corresponding essential cofactors. One pre-treament/wash with the enzyme system, another without the enzyme system.
3. Extraction of the fatty acid components from the soiled swatches: (i) Initial nil wash; (ii) Pre-treament/wash without the enzyme system; (iii) Pre-treament/wash with the enzyme system.
4. The Thin layer Chromatography (TLC) method is used to determine the quantitative level of lipids. The amounts of fatty acids are normalised versus (i) as 100% for the determination of % of fatty acid removal.
Steps 3 and 4 are described in the following lipid analysis:
1). Cut fabric to fit in 16×100 size test tube. Weigh cut fabric. Weigh fabric in test tube.
2). On balance. Add -10 g. of pure hexanes, weigh to nearest 0.001 g.
3). Sonicate sample for 10 minutes. Record final temperature and weight of test tube.
4). Weigh new clean, dry test tube. Decant liquid from sonicated sample into new test tube. Record weight.
5). Evaporate liquid sample under nitrogen.
6). Weigh dried residue in tube. Calculate residue as a percentage of fabric sample.
7). Quantitatively analyse lipids in residue using TLC.
Quantitive Determination of Lipid Levels
TLC Plates: 20 cm×20 cm, Analtech Silica Gel-G(#56027)
Sample Application: 10 μl Clay Adams, Accu-Fill 90 Micropet Disposable Pipettes
Detection: Sulfuric Acid Charring
Evaluation: Camag Scanner II densitometer
Standard Preparation : Oleic and stearic acids were used for the free fatty acids. Tristearin and triolein were used for the triglycerides. A standard of cholesterol was added to the mixture. Cholesteryl stearate and cholesteryl oleate were used to quantitate the cholesteryl esters. Stearyl palmitate and oleyl oleate was used for the wax esters. A standard of squalene was also added to the mixture. Squalane (dodecahydrosqualene) was used in the standard mixture to quantitate the class of compounds referred to as "hydrocarbons".
Single-step TLC Development (Quantitative)
The TLC plates were developed to 17.5 cm with a solvent system of hexane:ethyl ether:acetic acid at 160 mL:40 mL:2 mL. This development solvent gave the best resolution for the more polar lipids such as fatty acids, mono-, di-, and triglycerides. The wax esters, cholesteryl esters, squalene, and hydrocarbons all co-migrated in this system.
Analytic Detection
The TLC plates were allowed to dry in a hood for 15 minutes after development. The plates were then sprayed with 7 mL of 25% H2 SO4 and charred at 250° C. for 15-25 minutes. After charring, the TLC plates were evaluated with the Camag densitometer using absorbance in the transmission mode at 550 nm.
Analyte Quantitation
Quantitative analysis was accomplished by comparison of the area of each separate analyte with a calibration curve for the appropriate sebaceous lipid standards. The mass observed on the TLC plate was calculated from the calibration curve and then was converted to the units of μg/g of fabric. Unknown components on the TLC plate were quantitated from the calibration curve of the standard lipid with an Rf closest to that of the unknown.
Examples of suitable enzymes are the acid thiol ligase, desaturase and/or glutathione S-transferase enzyme.
It has been found that this type of enzyme increases the water-solubility of unsaturated fatty acid-containing stains/soils and thereby facilitates their removal. The detergent compositions of the present invention formulated therewith, provide body soils and/or oily/greasy soils and stain removal. Combinations of several enzymes that increase the water-solubility of fatty acid containing stains/soils, especially the combination of the acid-thiol ligase and desaturase enzymes, result in improved body soil and/or oily/greasy soil and stain removal.
The enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils, is incorporated into the compositions in accordance with the invention preferably at a level of from 0.0001% to 2%, more preferably from 0.005% to 0.5%, most preferably from 0.01% to 0.1% pure enzyme by weight of total composition.
Preferred enzymes that increase the water-solubility of saturated fatty acid-containing stains/soils for specific applications are alkaline enzymes, ie enzymes having an enzymatic activity of at least 10%, preferably at least 25%, more preferably at least 40% of its maximum activity at a pH ranging from 7 to 12. More preferred enzymes that increase the water-solubility of saturated fatty acid-containing stains/soils are enzymes having their maximum activity at a pH ranging from 7 to 12.
They may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. Origin can further be mesophilic or extremophilic (psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic, halophilic, etc.). Purified or non-purified forms of these enzymes may be used. These enzymes can be produced by the so called wild-type organism or by any host organism in which the gene responsible for the production of these enzymes that increase the water-solubility of fatty acid-containing stains/soils, has been cloned and expressed.
Acid Thiol Ligase Enzyme
Suitable acid-thiol ligases for the purpose of the present invention are described under EC 6.2.1. Preferred acid-thiol ligases are:
EC 6.2.1.3 Long-chain-fatty-acid-CoA ligase, also referred to as Acyl-CoA synthetase;
EC 6.2.1.10 Acid-CoA ligase, also referred to as Acyl-CoA synthetase;
EC 6.2.1.20 Long-chain-fatty-acid-ACP ligase, also referred to as Acyl-ACP synthetase.
Fatty Acid Acyl CoA Synthetase and Fatty Acid Acyl ACP Synthetase are commercially available acid-thiol ligases, sold by Sigma or Boehringer Mannheim. JP656064787 describes an acyl CoA synthetase preparation by cultivating Candida arborga strain; DE2917891 discloses a microbiological production of acyl CoA synthetase.
The acid-thiol ligase enzyme requires an esterification compound being a strong nucleophile and a source of energy being molecules having a free energy of hydrolysis greater or equal to 11 Kcal/mol. Examples of esterification compounds are Coenzyme A (CoA), Acyl Carrier protein (ACP), gluthathione (a tripeptide of cysteine, glutamic acidand glycine) or a polyamine such as N-(aminoethyl)ethyl amine (NH2 --CH2 CH2 --NH--CH2 CH3) and are available from Boehringer Mannheim or Sigma. They are generally comprised in the detergent compositions of the present invention at a level of from 0.01% to 10%, preferably from 0.1% to 5% by weight of total composition. Examples of such energy sources are Adenosine 5'-triphosphate (ATP), phosphoenolpyruvic acid, creatine phosphate, acetyl phosphate and are available from Boehringer Mannheim, Sigma or Aldrian. They are generally comprised in the detergent composition of the present invention at a level of from 0.01% to 10%, preferably from 0.1% to 5% by weight of total composition.
It has been established that one of the major components of the body soils, greasy and/or oily soil/stain are fatty acids. Without wishing to be bound by theory, it is believed that the acid-thiol ligase enzymes derivatise/esterify the fatty acids, rendering them more water soluble and thereby improve the cleaning of the washed surface.
Desaturase Enzyme
Suitable desaturases for the purpose of the present invention are the EC 1.14.99.5 Stearoyl-CoA desaturase and EC 1.14.99.6 Acyl-ACP desaturase.
Fatty acid ACP desaturase is a commercially available desaturase enzyme, sold by Dupont.
The desaturase enzyme requires an electron donor system, being a reducing agent which donates an electron to convert Fe3+ to Fe2+, corresponding to a redox potential above 0.771V. Examples of electron donor systems are ferrodoxin, Nicotinamide adenine dinucleotide phosphate reduced form (NADPH) and ferredoxin:NADPH(+) oxidoreductase wherein the NADPH can potentially be replaced by an effective reducing system composed of ferredoxin, grana (Spinach chloroplast) lamellae, ascorbic acid, dichlorophenolindophenol and light/dithiothreitol and reduced glutathione/dithionite or ascorbate such as described in Arcxh. Biochem. Biophys. 162, p158 (1974) and J. Biol. Chem. 243, p4626 (1968) and are available from Boehringer Mannheim or Sigma. They are generally comprised in the detergent composition of the present invention at a level of from 0.001% to 10%, preferably from 0.01% to 5% by weight of total composition.
Without wishing to be bound by theory, it is believed that the higher the unsaturation of fatty acids chains, the easier is their cleaning/removal. The desaturase enzyme is believed to introduce unsaturation in the fatty acids contained in the stains/soils and thereby facilitate their removal.
When the detergent compositions of the present invention comprise both the acid-thiol ligase and desaturase enzymes, these enzymes are preferably included in a weight ratio of pure enzyme of acid-thiol ligase to desaturase between 1:10 and 10:1, the most preferred weight ratio being 1:1.
Glutathione S-transferase enzymes are a group of cytosolic enzymes that catalyse the conjugation of the natural nucleophile tripeptide glutathione to reactive electrophiles generated in the cell. These enzymes are also believed to act as carriers of fatty acids in the cell, both saturated such as palmitic and stearic acids and unsaturated such as linoleic and arachidonic acids. Without wishing to be bound by theory, it is believed that the lipid binding properties of glutathione S-transferase enzymes in absence of its natural cofactor glutathione are useful in removing fatty acids stains from the fabrics.
Suitable glutathione S-transferase for the purpose of the present invention are described under EC 2.5.1.18. G6636 and G8642 are commercially available glutathione S-transferases, sold by Sigma.
Preferred additional ingredients to be used in the detergent compositions of the present invention, are enzymes, especially lipolytic enzymes, and/or polymeric soil release polymers.
In a preferred embodiment, the present invention relates to laundry and/or fabric care compositions comprising an enzyme that increases the water-solubility of fatty acid-containing stains/soils (Examples 1-18). In a second embodiment, the present invention relates to dishwashing or household cleaning compositions (Examples 19-26).
The detergent compositions according to the invention can be liquid, paste, gels, bars, tablets, powder or granular forms. Granular compositions can also be in "compact" form, the liquid compositions can also be in a "concentrated" form.
Such compositions containing an enzyme that increases the water-solubility of fatty acid-containing stains/soils can provide fabric cleaning, stain removal, whiteness maintenance, softening, color appearance and dye transfer inhibition when formulated as laundry detergent compositions.
Conventional Detergent Enzymes
The detergent compositions can further comprise one or more enzymes which provide cleaning performance and/or fabric care benefits in addition to an enzyme that increases the water-solubility of saturated fatty acid-containing stains/soils. Indeed, it has been found that the detergent compositions of the present invention further comprising another detergent enzyme, especially a lipase, provide improved cleaning performance on body soils and/or oily/greasy soils and stains.
Said enzymes include enzymes selected from cellulases, hemicellulases, peroxidases, proteases, gluco-amylases, amylases, xylanases, lipases, phospholipases, esterases, cutinases, pectinases, keratanases, reductases, oxidases, phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, malanases, β-glucanases, arabinosidases, hyaluronidase, chondroitinase, laccase or mixtures thereof.

Other amylases known for use in cleaning compositions include both α- and β-amylases. α-Amylases are known in the art and include those disclosed in U.S. Pat. No. 5,003,257; EP 252,666; WO/91/00353; FR 2,676,456; EP 285,123; EP 525,610; EP 368,341; and British Patent specification no. 1,296,839 (Novo). Other suitable amylases are stability-enhanced amylases described in WO94/18314, published Aug. 18, 1994 and WO96/05295, Genencor, published Feb. 22, 1996 and amylase variants having additional modification in the immediate parent available from Novo Nordisk ANS, disclosed in WO 95/10603, published April 95. Also suitable are amylases described in EP 277 216, WO95/26397 and WO96/23873 (all by Novo Nordisk). Examples of commercial α-amylases products are Purafect Ox Am® from Genencor and Termamyl®, Ban®, Fungamyl® and Duramyl®, all available from Novo Nordisk A/S Denmark.

The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. Origin can further be mesophilic or extremophilic (psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic, halophilic, etc.). Purified or non-purified forms of these enzymes may be used. Also included by definition, are mutants of native enzymes. Mutants can be obtained e.g. by protein and/or genetic engineering, chemical and/or physical modifications of native enzymes. Common practice as well is the expression of the enzyme via host organisms in which the genetic material responsible for the production of the enzyme has been cloned.
Said enzymes are normally incorporated in the detergent composition at levels from 0.0001% to 2% of pure enzyme by weight of the detergent composition. The enzymes can be added as separate single ingredients (prills, granulates, stabilized liquids, etc. containing one enzyme) or as mixtures of two or more enzymes (e.g. cogranulates).
The detergent compositions can further comprise a polymeric soil release agent in addition to an enzyme that increases the water-solubility of fatty acid-containing stains/soils. Indeed, it has been found that the detergent compositions of the present invention further comprising a polymeric soil release agent, provide improved cleaning performance on body soils and/or oily/greasy soils and stains.
