(57) The invention pertains to aqueous liquid thickened chlorine bleaching compositions comprising an alkali metal hypochlorite solution thickened by a combination of at least two different detergent-active components, one of which comprises a trialkylamineoxide having two short alkyl groups and one long chain C₈-C₁₈ alkyl group, at least 20% by weight of the amineoxide component having C₁₆-C₁₈ alkyl groups. The invention provides improved thickening action and allows reduced levels of the thickening detergent-active system.
