PURPOSE:To improve a bleaching and cleaning effect by incorporating a nonionic surfactant, a zeolite, a peroxide, an org. peroxy acid precursor and a specified copolymer. CONSTITUTION:A bleaching detergent compsn. comprising 8-35wt.% (hereinbelow described as %) nonionic surfactant (A) (e.g. a polyoxyethylene alkyl ether with an alkyl group of a mean carbon number of 10-20 and 1-30mol of ethylene oxide added thereto), 20-60% synthetic crystalline zeolite (B), 5-20% peroxide (C) generating H2O2 in a water-soluble soln. (e.g. sodium perborate hydrate), 1-10% org. peroxy acid precursor (D) reacting with H2O2 of formula I, II, etc., to give an org. peroxy acid having a group of formula III, 1-5% copolymer (E) with the units of formula IV [wherein M is H, alkali (alkaline earth) metal, a (substd.) ammonium] in the molecule and an average mol.wt. of 800-1,000,000 (e.g. a maleic acid-acrylic acid copolymer) and 0.5-2% bleaching stabilizer (F) [e.g. aminotri(methylene)phosphonic acid] and which does not contain 0.1% or more phosphate. |
