  • Patent number: 5505740
    Abstract: A bleaching product and a method of removing soils from fabrics by contacting the fabrics in an aqueous wash solution with a product comprising a peracid precursor, a source of hydrogen peroxide and a source for delayed release of an acid into the wash solution to initially permit effective in situ formation of peracid, the acid thereafter reducing the pH of the wash solution for enhancing bleach performance of the peracid. The source of the acid may be included in the bleaching product, for example, as an acid of delayed solubility, an acid coated with a low solubility agent or an acid generating species, or independent of the bleaching product. The acid source is selected to be compatible with the peracid or precursor and adjuncts.
