ABSTRACT:
A bleach granule is provided with 60-100% being an intimate mixture of an amido or imido C.sub.2 -C.sub.30 peroxy acid and a surfactant, in a weight ratio of 20:1 to 1:20. The most preferred peroxyacids are N,N-phthaloylaminoperoxycaproic acid (PAP); monononylamide of either peroxysuccinic acid (NAPSA) or peroxyadipic acid (NAPAA) and N,N'-terephthaloyl-di(6-aminoperoxycaproic acid) (TPCAP). Localized dye damage from the peroxy acid bleach is prevented by the presence of the surfactant. Bleach compositions and a method for cleaning a stained substrate with the bleach granule are also described.
