11 Case 150-5186 2206602 IMPROVEMENTS IN OR RELATING TO ORGANIC COMPOUNDS
This invention relates to liquid laundry detergent compositions for use in domestic and industrial laundering.
Such liquid detergents mostly consist of a mixture of anionic and non-ionic surfactants, but no builders, so that their washing power for fatty stains is only moderate despite their high surfactant content (40 X). For good washing effect on protein-containing stains it is also necessary to include enzymes in the formulation.
According to the invention, there is provided a stable liquid builder-free detergent composition comprising the carboxymethylated or carboxyethylated reaction product of a fatty alcohol or an alkylphenol with ethylene oxide (hereinafter defined as component a); b) one or more fatty acid salts (hereinafter defined as component b); and one or more further anionic tensides (hereinafter defined as component c).
t Case 150-5186 A preferred composition according to the invention comprises:
is thereof; group; I.
a) 1-25 % of component a) b) 5-30 % of component b) c) 2-20 % of component c) and d) 25-80 % water together with sufficient alkali to bring the pH of the composition within the range from 6.5 to 8 (preferably 7-7.5, more preferably 7.5). A more preferred composition according to the invention comprises: a) 420 b) 10-25 c) 515 of component a) of component b) of-component c); and d) 40-80 % water together with sufficient alkali to bring the pH of the composition within the range from 6.5 to 8 (preferably 7 to 7.5, more preferably 7.5).
Normally components a) to c) are present in an amount in the range 20 to 50 % preferably 30 to 50 % inclusive of the composition Preferably component a) is a compound of formula I or a salt R1-0(CH2CH20)n-(R2-COOH), (1) in which R, is C822alkyl; CS-22alkenyl or C4-18alkylphenyl R2 is methylene or ethylene; is a number from 1 to 20; and is an average value from 0.1 to 1.
Compounds of formula I are known or can be made from known compounds by known methods.
Preferably R, is the C12-15alkyl residue of lauryl alcohol.
Preferably n is 4-5.
Preferably R2 is -CH2-.
1 1 Case 150-5186 Preferably the compound of formula I is the reaction product of a synthetic C12-15 lauryl alcohol with 4-5 moles of ethylene oxide, carboxymethylated with 0.8 moles of chloroacetic acid.
For the avoidance of doubt although compounds of formula I have been represented in their acid form, when the compositions of the invention are alkaline, they will be in salt form (preferably alkali metal salt form e.g. Na salt form). Therefore reference to the free acid includes such salt forms as well.
Preferred fatty acids of component b) are CS-22 unsaturated or saturated carboxylic acids, more preferably C12-18 saturated or unsaturated carboxylic acids.
Component b) can be added to compositions according to the invention as the free acid, which can be converted by the addition of alkali (e.g. NaOH, KOH or an organic base such as triethanolamine) to the salt form or they may be added directly in the salt form.
1 Preferred anionic surfactants of component c) may be any of the following conventional types: a) sulphates and sulphonates of fatty acids, fatty acid esters and fatty acid amides; b) linear or branched C5-18alkyl sulphates and sulphonates; c) sulphated ethoxylated compounds, particularly sulphated forms of any non-ionic surfactants; d) polycarboxylic acid ester sulphonates; and e) C5-18alkylbenzenesulphonates and Cl-4alkyl and 25 di-Cl- 4alkylnaphthalene sulphonates.
These compounds may be added to the composition in free acid form and converted to their salt forms by addition of alkali or added -Case 150-5186 directly in salt form.
Compositions according to the invention may contain one or more of the following additives: - a hydrotrope, a sequestering agent, a buffer,an enzyme and an optical brightener.
Preferred hydrotropes which may be present include for example urea, dicyandiamide and its derivatives, alcohols, water-soluble glycols, glycol ethers and glycol esters and Cl-4alkylbenzene sulphonates, provided that the compounds display no cloud point in distilled water up to 1001C. They act so as to prevent phase separation, that is to stabilise the liquid composition.
Preferred sequestering agents include citric acid, nitrilotriacetic acid and other complex formers.
"referred buffers which may be added to compositions according to the invention to stabilise the pH of the wash liquor in the neutral or alkali region, include sodium bicarbonate, sodium carbonate and sodium silicate.
Preferred enzymes which may be used include proteases and amylases.
Preferred optical brighteners that may be used include mono- or di-sulphonic acid stilbene derivatives.
By selection of any of these additional components, the washing effect of the liquid detergent can be adjusted according to the desired field of use. The liquid detergent compositions of the invention are primarily useful as domestic laundry detergents. Not only do they display good washing power, they also produce a soft handle on laundered cotton goods. Being phosphate-free, they are ecologically acceptable. Compositions according to the invention when used in conjunction with optical brighteners do not cause quenching of the brightener, so that acceptable grades of whiteness are obtained. The liquid compositions are stable and do not separate into two phases on storage.
w Case 150-5186 The following Examples, in which all percentages are percentages by weight of the entire composition, illustrate the invention.
Example 1

a) 12 % of the compound of formula la R-0-(CH2CH204-5-(CH2-COONa)0.8 (1a) where R is a C12-15alkyl group (the compound of formula la being added in the form of a 50 % aqueous paste); b) 15 % coco fatty acid; c) 15 % dodecylbenzene sulphonic acid; d) 5 % triethanolamine; e) 11.6 of a 30 % NaOH solution; f) 10 % ethanol; g) 1 % of an optical brightener of formula 1b, NH-G -CH=CH---NH N (1b) SO H SO H O"H--e 3 3 ?HN N CH 2 CH2 CONH2 H 2 CH2 OH 9-HN-- 0/ -CH 2CH2CONH2 H2CH20H and h) 30.4 % of demineralised water is made up by adding the components a) to g) to demineralised water stirring until a homogeneous solution is obtained at a pH of 7.5.
