Thickened, pourable liquid bleaching compositions which have been thickened with the aid of two different detergent-active materials, e.g. a tertiary amine oxide with a saturated fatty acid soap or an alkali metal sarcosinate often show a decrease in viscosity on storage of the composition. By inclusion of a third, synthetic detergent of the sulphate or sulphonate type, e.g. an alkylethersulphate, compositions are obtained with a significantly reduced decrease of viscosity during storage, particularly over longer periods and at higher storage temperatures. The compositions are useful for bleaching hard surfaces.

Liquid thickened bleaching composition

Aqueous bleaching compositions can be satisfactorily colored by inclusion therein of a colored polymer latex which consists of a copolymer of a hydrophobic monomer with a reactive copolymerizable monomer containing a chromophore. These colored polymer latices are particularly suitable for coloring hypochlorite-containing bleaching compositions.
