CLEANING COMPOSITION FOR FABRIC WASHING AND METHOD

DOMESTIC TISSUE TREATMENT Field of Invention

[0001] The present invention relates to a composition for washing fabrics. Background of the Invention

[0002] There is a desire to use less water for domestic laundry washing. This can be achieved by reducing the number of water rinses performed after the initial wash. The reduction in the number of rinses increases the redeposition of dirt removed in the wash, thus reducing the general cleaning. The problem is exacerbated by the presence of human tallow in the garments and in the washing liquid that serves to enhance the deposition of dirt in the wash. There is a need to improve dispersants to avoid depositing dirt present in the washing liquid on the fabric. These ingredients are preferably biodegradable and increase stain removal. Summary of the Invention

[0003] There is a need for technologies to reduce redeposition and improve cleaning in household fabric washing products.

[0004] We found that selected alkoxylated dispersants (AD), when incorporated into fabric washing detergents, enhance the whiteness and luster of fabrics during domestic fabric washing.

[0005] In a first aspect, the present invention provides a cleaning composition for washing fabrics which comprises: (i) from 0.2 to 20% by weight, preferably from 0.5 to 12% by weight, with the maximum preference of 1 to 10% by weight of an alkoxylated dispersant of the following structure:

, (Formula 1) where: - X is selected from: ethoxy; and mixtures of ethoxy and propoxy groups, where the number of ethoxy groups is greater than the number of propoxy groups, and where n ranges from 6 to 70; - m is selected from: 2 and 3; - R1 is selected from: uncharged C12 to C20 alkyl groups; uncharged aryl groups; and uncharged alkyl-aryl groups in which the alkyl-aryl alkyl group is a linear or branched saturated C1 to C3. - T is selected from: H; CH3; SO3-; CH2COO-; PO32-; C2H5; n-propyl, i-propyl; n-butyl; t-butyl and sulfosuccinate; (ii) from 0 to 50% by weight of surfactant, other than the alkoxylated dispersant; and, (iii) an asset selected from one or more of the following: from 0.001 to 3% by weight of perfume; from 0.0001 to 0.5% by weight of fluorescent agent; and, from 0.0001% by weight to 0.1% by weight of an enzyme.

It is also advantageous to encapsulate fragrance components that have a low CLog P (that is, those that will have a greater tendency to be divided into water), preferably with a CLog P below 3.0. These relatively low boiling point and relatively low CLog P materials have been termed “late blooming” fragrance ingredients and include one or more of the following materials:

[0089] Enzymes may be present as a whole or part of the active ingredient in the cleaning composition for washing fabrics.

[0090] One or more preferred enzymes are preferably present in the tissue washing composition of the invention and when practicing a method of the invention.

[0091] If present, then the level of each enzyme in the tissue washing composition of the invention is 0.0001% by weight to 0.1% by weight.

[0092] The levels of enzyme present in the composition preferably refer to the level of enzyme as pure protein.

The contemplated enzymes include proteases, alpha-amylases, cellulases, lipases, peroxidases / oxidases, pectate lyases and mannanases, or mixtures thereof.

[0094] Preferably, the enzyme is selected from: proteases, alpha-amylases;

cellulases and lipases.

[0095] Suitable lipases include those of bacterial or fungal origin. Chemically modified or genetically engineered protein mutants are included. Examples of useful lipases include Humicola lipases (synonymous with Thermomyces), for example, H. lanuginosa (T. lanuginosus), as described in EP 258 068 and EP 305 216 or H. insolens as described in WO 96 / 13580, a Pseudomonas lipase, for example, from P. alcaligenes or P. pseudoalcaligenes (EP 218 272), P. cepacia (EP 331 376), P. stutzeri (GB 1,372,034), P. fluorescens, strain of the species Pseudomonas SD 705 (WO 95/06720 and WO 96/27002), P. wisconsinensis (WO 96/12012), a lipase from Bacillus, for example, from B. subtilis (Dartois et al. (1993), Biochemica et Biophysica Acta , 1131, 253-360), B. stearothermophilus (JP 64/744992) or B. pumilus (WO 91/16422).

[0096] Other examples are variants of lipase, such as those described in WO 92/05249, WO 94/01541, EP 407 225, EP 260 105, WO 95/35381, WO 96/00292, WO 95/30744, WO 94 / 25578, WO 95/14783, WO 95/22615, WO 97/04079 and WO 97/07202, WO 00/60063.

[0097] Preferred commercially available lipase enzymes include Lipolase ™ and Lipolase Ultra ™, Lipex ™ and Lipoclean ™ (Novozymes A / S).

[0098] The method of the invention can be performed in the presence of phospholipase classified as EC 3.1.1.4 and / or EC 3.1.1.32. As used here, the term phospholipase is an enzyme that has activity in relation to phospholipids.

[0099] Phospholipids, such as lecithin or phosphatidylcholine, consist of glycerol esterified with two fatty acids in an external (sn-1) and intermediate (sn-2) position and esterified with phosphoric acid in the third position; phosphoric acid, in turn, can be esterified to an amino alcohol. Phospholipases are enzymes that participate in the hydrolysis of phospholipids. Several types of phospholipase activity can be distinguished, including phospholipases A1 and A2 that hydrolyze a fatty acyl group (in the sn-1 and sn-2 positions,

respectively) to form lysophospholipids; and lysophospholipase (or phospholipase B), which can hydrolyze the remaining fatty acyl group into lysophospholipid. Phospholipase C and phospholipase D (phosphodiesterases) release diacyl glycerol or phosphatidic acid, respectively.

[0100] Protease enzymes hydrolyze the bonds within peptides and proteins; in the context of tissue washing, this results in greater removal of stains containing protein or peptide. Examples of suitable protease families include aspartic proteases; cysteine proteases; glutamic proteases; asparagine peptide lyase; serine proteases and threonine proteases.

FABRICS Component% by weight Monopropylene glycol 2.2 Triethanolamine 1.5 C12-C15 alcohol ethoxylate with 7 moles of 1.2 ethylene oxide Linear alkylbenzene sulfonate 4.6 Sodium lauryl ether sulfate with 1 mol of ethylene oxide 5, 8 Citric acid 2.0 CaCl2 dihydrate 0.2 NaCl 0.2 Tinopal® CBS-X (BASF fluorescent agent) 0.3 Sodium hydroxide up to pH = 8.4 Exemplary dispersants see text Water balance Application Example 1 - Anti-replenishment benefit

[0161] The formulation was used to wash eight pieces of 5 x 5 cm cotton knitted cloth in a thermometer set at 200 rpm (revolutions per minute). An hour wash was carried out in 800 ml of water with French 26 ° hardness at 20 ° C, with 2.3 g / L of the formulation shown in Table II. To simulate a particulate dirt that could be redeposited, 0.04 g / L of 100% compressed carbon black (ex Alfa Aesar) was added to the washing liquid. To simulate oily sebum dirt, 7.2 g of an SBL2004 dirt slide (ex Warwick Equest) was added to the washing liquid.

[0162] As soon as the wash was completed, the cotton samples were rinsed once in 400 mL of clean water, removed, dried and the color was measured on a reflectometer and expressed as the CIE values L * a * b *. The antiredeposition benefit was expressed as the ΔL value:

ΔL = L * (dispersant) - L * (control)

[0163] The higher the ΔL value, the greater the prevention of carbon black dirt deposition. The 95% confidence limits based on the 8 separate cotton samples were calculated.

[0164] The formulations were made with and without the addition of 8.7% by weight of the dispersants in Table I. The results are given in Table III.
