ABSTRACT:
An activated peroxy compound bleaching composition includes a peroxy bleaching compound, such as sodium perborate, and an activator for such bleaching compound, which improves the bleaching effect thereof, which activator is a sulfonyl halide, such as an alkoxybenzenesulfonyl halide, preferably an ortho- or para-substituted methoxybenzenesulfonyl chloride, such as p-methoxybenzenesulfonyl chloride. Preferably, the peroxy bleaching compound and activator are included in a synthetic organic detergent composition such as one based on anionic and/or nonionic normally solid detergent(s), preferably also with builder salt(s) present, and bleaching is effected during the washing of fabrics or articles made thereof, in wash waters of various temperatures, even in water which is only warm. The bleaching compound and activator may also be included in pre-soak compositions.
