First Claim
Patent Images
1. A detergent composition comprising:
- (A) from about 1% to about 90% of an alkylpolysaccharide detergent surfactant of the formula RO(R'"'"'O)y (Z)x where R is an alky, hydroxy alkyl, alkyl phenyl, hydroxy alkyl phenyl, alkyl benzyl, or mixtures thereof, said alkyl groups containing from about 8 to about 18 carbon atoms;
where each R'"'"' contains from 2 to about 4 carbon atoms and y is from 0 to about 12; and
where each Z is a moiety derived from a reducing saccharide selected from the group consisting of glucose, galactose and mixtures thereof, and x is a number from about 11/2 to about 3;
(B) from about 1% to about 90% of a polyethoxylate nonionic detergent surfactant; and
(C) from 0% to about 90% of a detergency builder, the ratio of (A) to (B) being from about 1;
3 to about 10;

Abstract
Detergent surfactant combinations comprising alkylpolyglycoside detergent surfactants and nonionic detergent surfactants provide good detergency and are compatible with anionic optical brighteners, both in built and unbuilt detergent compositions.
