Neutral or alkaline thickened aqueous hydrogen peroxide compositions and processes for the production thereof are provided. The compositions are thickened with a polymeric thickener comprising a polyethylene backbone, pendant carboxyl groups and pendant groups of the formula -(OCH2CH2)m(OCHXCHY)n-O-R, where m is a positive integer, n is zero or a positive integer, X and Y are independently selected from hydrogen atoms, methyl and ethyl groups and R is a hydrophobic group comprising 8 or more carbon atoms; and one or more surfactants selected from the group consisting of alcohol ethoxylates, alkylbenzenesulphonates comprising 10 or more carbon atoms, alkylsulphates comprising 6 or more carbon atoms, alcohol ether sulphates, alpha-sulphoesters and alkylglucosides. |
