Abstract
A stable aqueous detergent composition is provided in liquid or gel form containing from 10 to 80% by weight of an active detergent mixture comprising primary alkyl sulphate in an amount of 15 to 75% by weight of the active detergent plus betaine and/or amine oxide in an amount of 10 to 40% by weight of the active detergent mixture. Primary alkyl sulphate having chains of 10 or 11 carbon atoms provides at least 25% by weight of the primary alkyl sulphate present. The betaine and/or amine oxide is at least two thirds of the amount by weight of any primary alkyl sulphate having carbon atom chains of 12 carbon atoms or longer. The C.sub.10 and/or C.sub.11 alkyl sulphate is surprisingly effective as a detergent in such compositions despite higher water solubility than longer chain alkyl sulphate. It can enhance mildness compared to longer chain alkyl sulphate, and can replace or partially replace alkyl ether sulphate. Nonionic detergent may be included to enhance mildness further.
