Abstract
A concentrated aqueous surfactant solution comprising alkyl ether sulphate and alkaline earth metal, preferably magnesium. The composition is a stable liquid which is suitable for making into cleaning products, especially dish washing liquids. The concentrated surfactant solution can be prepared by partial neutralisation of the acid precursor with the hydroxide or oxide of the alkaline earth metal, followed by a further neutralisation with the hydroxide of an alkali metal or ammonium.
