Abstract
Alkyl ether sulphates are disclosed that are derived substantially wholly from C.sub.12 and C.sub.13 alcohols, at least 50% by weight being branched at the 2-position and at least 30% by weight being 2-ethyl or more highly branched. Foaming detergent compositions containing an alkylbenzene sulphonate and/or a dialkyl sulphosuccinate in combination with an alkyl ether sulphate of this specific type exhibit excellent foaming and detergency and are especially suitable for hand dishwashing.
Claims9
A foaming detergent composition comprising from 2 to 95% by weight of an active detergent system consisting essentially of:
- (a) a linear C.sub.8 -C.sub.14 alkylbenzene sulphonate and/or a C.sub.4 -C.sub.10 dialkyl sulphosuccinate, and
- (b) an alkyl ether sulphate of the formula I
- R.sub.1 --O--(CH.sub.2 CH.sub.2 O).sub.n --SO.sub.3 X.sub.1 (I)
- wherein R.sub.1 is an alkyl group, the average degree of ethoxylation n is from 2 to 7 and X.sub.1 is a solubilising cation, the alkyl ether sulphate of the formula I consisting substantially wholly of material in which the group R.sub.1 has 12 to 13 carbon atoms, and comprising at least 55% by weight of material in which the group R.sub.1 is branched at the 2-position, and comprising at least 35% by weight of material in which the group R.sub.1 carries at the 2-position an alkyl group containing 2 or more carbon atoms,
- the weight ratio of (a) to (b) being within the range of from 2:1 to 0.5:1.
