Abstract
Stable, high-concentration (60-80% active matter) aqueous liquid detergent compositions based on dialkyl sulphosuccinates and alkyl ether sulphates contain a lower alcohol, preferably ethanol, and water, the ratio of lower alcohol to water exceeding a critical ratio which varies with the total active detergent content. The compositions may be thickened by means of hydroxypropyl guars, polyethylene oxides, or hydrophilically substituted cellulosic polymers such as hydroxyethyl cellulose.
