摘要

There is provided a bleaching composition containing an oxygen-releasing bleach system preferably comprising a hydrogen peroxide source and a peroxyacid bleach precursor compound, a transition metal containing bleach catalyst and a clay mineral compound. Preferably the composition also contains a clay flocculating agent. The composition is useful in the bleaching of stains from stained coloured fabrics. The clay mineral compound acts to inhibit the fading of the colour of said fabrics during the stain bleaching process.
