Abstract
High-concentration (60-80% active matter) detergent compositions in the form of stable, translucent, mobile gels based on dialkyl sulphosuccinates and alkyl ether sulphates, and containing a lower alcohol and water, are disclosed. For stability, the ratio of lower alcohol to water should be below a certain critical value that varies with the total active detergent level.
Claims17
A homogeneous foaming detergent composition in gel form consisting essentially of
- (a) from 60 to 80% by weight of an active detergent system consisting essentially of
- (i) from 20 to 65% by weight of a water-soluble monovalent salt of a C.sub.3 -C.sub.12 dialkyl ester of sulphosuccinic acid in which the alkyl groups may be the same or different,
- (ii) from 12 to 55% by weight of a monovalent salt of a C.sub.10 -C.sub.18 alkyl ether sulphate, the ratio of [i] to [ii] being from 4:1 to 0.5:1, and
- (iii) optionally a nonionic detergent, in an amount insufficient to cause instability of the composition,
- (b) from 2 to 10.5% by weight of a C.sub.2 -C.sub.3 mono- or polyhydric alcohol, and
- (c) water and minor ingredients to 100%,
- the ratio of alcohol (b) to water being below a critical value g which is selected for the given active detergent system as the value of said ratio above which separation into two phases occurs, said value being in the range of from 0.25 to 0.41 and being dependent on the total active detergent concentration.
