Abstract
Improved light duty cleaning compositions comprising 15-50% surfactant on product can be formulated such that they comprise, on surfactant: PA1 a) 50-70% wt of a mixture of primary alkyl sulphate and alkyl ether sulphate, wherein the average ethoxylation value of the mixture is 0.5-2.5, PA1 b) 2-8% wt of a betaine, an amine oxide or a mixture of betaine and amine oxide, and, PA1 c) 25-45% wt of an alkylpolyglucoside surfactant. It is believed that compositions which have an excess in surfactant of a mixture of both primary alkyl sulphate and alkyl ether sulphate in a specified ratio, i.e. such that the total EO is 0.5-2.5, together with a lesser, but significant level of APG and a minor amount of betaine, provide an acceptable combination of mildness, cleaning and foaming under a broad range of conditions and show surprising benefit in a bowl-wash situation.
