Compsn. contains: (A) H2O2; (B) anionic and/or a nonionic surfactant(s); and (C) one or a mixt. of glutaric acid and it's salt. The compsn. pref. contains a polyethylene glycol. Available anionic surfactants include 4-12C alkyl diphenyl ether disulphonates, 8-12C alkyl, phenol polyoxyethylene (3-10 mols) ether sulphates and polyoxyethylene(1-5 mol) 10-16C alkyl ether sulphates. Available nonionic surfactants include ethylene oxide and propylene oxide adducts of 8-24C higher alcohols, polyhydric alcohols, fatty acids and alkyl phenols. The blend ratio is pref. 1.5-5 wt.% (A), 12-5 wt.% (B) and 1-6 wt.% (C). Pref. the polyethylene glycol is 0.5-5 wt.% and has a molecular wt. of 100-2000.
