Abstract 948,240. Liquid detergent compositions. PROCTER & GAMBLE CO. May 25, 1962 [May 27, 1961], No. 20227/62. Heading C5D. An aqueous non-alcoholic detergent composition comprises by weight (a) 20-40% of a mixture of (i) one or more C9-18-alkyl benzene sulphonates, preferably sodium dodecylbenzene sulphonate, and (ii) one or more C10-18-alkyl polyoxyethylene sulphates having 2-4 ethylene oxide units in the molecule, preferably coconut alcohol tri-(oxyethylene) sulphate, the cations present in (i) and (ii) being sodium and/or potassium and/or ammonium and the weight ratio of (i) to (ii) being preferably 0.5: 1 to 3 : 1 and most suitably about 1:1; (b) 0.5-5% of a C10-16-fatty acyl alkanolamide, preferably coconut monoethanolamide; (c) 6-18% of sodium and/or potassium and/or ammonium toluene and/or xylene sulphonates, a 2:1 mixture by weight of potassium toluene sulphonate and sodium xylene sulphonate being preferred; and (d) the balance being substantially water. Perfume, colour, optical bleach, anti-tarnish agents, opacifiers, oxidizing agents and buffers may also be present.
A LIQUID DETERGENT COMPOSITION WHICH CONSISTS ESSENTIALLY OF ABOUT 10 TO 18% BY WEIGHT OF A MIXTURE OF AN ALKALI METAL HIGHER ALKYL BENZENE SULFONATE DETERGENT, SAID HIGHER ALKYL GROUP HAVING ABOUT 8 TO 15 CARBON ATOMS, AN ALKALI METAL ALKYL POLYETHOXAMER SULFATE SALT HAVING ABOUT 10 TO 18 CARBON ATOMS IN THE ALKYL GROUP AND AN AVERAGE OF ABOUT 2 TO 15 MOLES OF ETHYLENE OXIDE, THE RATIO OF SAID ALKYL BENZENE SULFONATE TO POLYTHOXAMER SULFATE BEING FROM ABOUT 6.5:1 TO ABOUT 1:4 BY WEIGHT; A TOTAL OF ABOUT 10 TO 20% BY WEIGHT OF WATER-SOLUBLE POTASSIUM POLYPHOSPHATE, ABOUT 6 TO 12% BY WEIGHT OF A HYDROTROPIC SALT SELECTED FROM THE GROUP CONSISTING OF SODIUM AND POTASSIUM SALTS OF XYLENE, TOLUENE, ETHYLBENZENE AND ISOPROPYLBENZENE SULFONAT,E N-AMYL AND N-HEXYLSULFATE, AND MIXTURES THEREOF, ABOUT 2 TO 10% BY WEIGHT OF A HIGHER FATTY ACID ALKYLOLLAMIDE HAVING 8 TO 18 CARBON IN THE ACYL RADICAL AND UP TO 3 CARBON ATOMS IN EACH ALKYLOL GROUP, AND THE BALANCE BEING SUBSTANTIALLY WATER, THE COMPOSITION CONTAINING SAID INGREDIENTS FORMING IN AN AQUEOUS SOLUBILIZING MEDIUM A HOMOGENEOUS, POURABLE, CLEAR LIQUID AT ROOM TEMPERATURE.
