Stable bleaching detergent composition

Claim 1

A stable bleaching detergent composition, consisting essentially of: A. from about one to about 30 percent by weight of a surfactant selected from the group consisting of water-soluble anionic surfactant, water-soluble nonionic surfactant, water-soluble amphoteric surfactant and mixtures thereof; B. from about one to about 50 percent by weight of an inorganic peroxygen compound capable of releasing oxygen in aqueous solution; C. the balance is a substance selected from the group consisting of water-soluble neutral inorganic builder salts, water-soluble alkaline inorganic builder salts, water-soluble organic builders and mixtures thereof; and D. from 0.001 to 5 parts by weight, per 100 parts by weight of the sum of the weights of A plus B plus C, of a compound or mixture of compounds having the formula ##STR35## wherein R 1 is hydrogen or alkyl having one to 3 carbon atoms; ##STR36## is a monovalent radical of an unsaturated 5 member or 6 member heterocyclic ring containing only nitrogen and carbon atoms in the ring, or said heterocylic ring fused to a benzene ring or another heterocyclic ring to give a polycyclic radical having the characteristic ##STR37## grouping; R 2 is hydrogen, unsubstituted alkyl having one to 10 carbon atoms, alkyl having one to 10 carbon atoms substituted with hydroxy, chloro, amino, alkoxy (C 1 to C 10 ), phenoxy, phenyl, hydroxyphenyl or benzoylamino, unsubstituted phenyl, phenyl substituted with one or two alkyls (C 1 to C 2 ), chloro, hydroxy, alkoxy (C 1 to C 10 ), acyloxy (C 1 to C 4 ) or amino, aroyl having 6 to 8 carbon atoms, pyridyl or oxopyrrolidinyl; R 3 is hydrogen, unsubstituted alkyl having one to 22 carbon atoms, alkyl having one to 22 carbon atom substituted with hydroxy, chloro, alkoxy (C 1 to C 4 ), phenoxy, phenyl or amino, phenyl, phenyl substituted with one or 2 alkyls having one or 2 carbon atoms or alkoxy (C 1 to C 10 ), aroyl having 6 to 8 carbon atoms, alkoxy having one to 10 carbon atoms, phenoxy, halogen, alkylamino (C 1 to C 10 ), aminosulfonamido, alkanoyloxy (C 2 to C 6 ), aroyloxy (C 6 to C 8 ), carbamoyl, alkoxy (C 1 to C 10 ) carbonyl and aryl (C 6 to C 8 ) oxycarbonyl, or R 3 and R 4 together form a benzo group; and R 4 is hydrogen or --R 5 Y, in which R 5 is alkylene having one to 6 carbons, alkylidene having one to 6 carbons or phenylene, and Y is a radical obtained by removing R 4 from a compound of said formula.
