Claims8
A particulate laundry detergent composition having enhanced soil release and cleaning properties comprising:
- (a) from about 2% to about 25% by weight of a surface-active agent selected from the group consisting of anionic, nonionic, zwitterionic, and ampholytic detergents and mixtures thereof;
- and
- (b) from 0.25-0.75% of an amine oxide having the formula ##STR3## wherein R is an alkyl or alkenylgroup having 10 to 22 carbon atoms, the R.sub.1 's which are identical or different are selected from C.sub.1-4 alkyl, ethylene oxide and propylene oxide, n is an integer from 1 to about 6, m is an integer from 0 to about 6, p is 0 or 1, x, y, and z are each 1 for alkylsubstituents, and integers in the range from 1 to 10 for ethylene oxide or propylene oxide substituents such that the sum of (x+y+z) is not greater than 25,
- (c) from about 3% to about 50% by weight of a peroxybleach compound;
- and
- (d) from about 1% to about 50% by weight of a detergent builder;
- whereby a 1% aqueous solution of the composition, measured at 20.degree. C., has a pH in the range from about 8.5 to about 11.
