Abstract (en)
There is provided a bleaching composition containing a clay mineral compound and an oxygen-releasing bleach system comprising a hydrogen peroxide source and a peroxyacid bleach precursor compound selected from the group consisting of (i) a perbenzoic acid, or non-cationic substituted derivative thereof, precursor compound; (ii) a cationic peroxyacid bleach precursor compound; and any mixtures thereof wherein the weight ratio of clay mineral compound to peroxyacid bleach precursor compound is from 10:1 to 1:5. The composition preferably contains additionally 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.
