Claims6
A detergent composition comprising
- (a) from 0.05% to 4.5%, by weight of the detergent composition, of a cationic surfactant of the formula
- in which R1 is a hydroxyalkyl group having no greater than 6 carbon atoms;
- each of R2 and R3 is independently selected from C1-4 alkyl or alkenyl;
- R4 is C12-14 alkyl or alkenyl and X− is an anion selected from the group consisting of halide, methyl sulfate, sulfate, and nitrate;
- (b) a hydrophobic organic peroxyacid bleaching system, capable of providing a peroxyacid compound of the formula:
- wherein R5 is an alkyl, aryl or aralkyl group containing from 1 to 14 carbon atoms, R7 is an alkylene, arylene or alkarylene group containing from 1 to 14 carbon atoms, and R6 is H or an alkyl, aryl or alkaryl group containing from 1 to 10 carbon atoms;
- and
- (c) from 5% to about 40% by weight of sodium sulfate said composition having a pH as measured in 1% water solution from 10.0 to 11.0.
