1. A detergent composition comprising:
- (a) from about 0.005% to about 99% by weight of an alpha-substituted compound having the formula;
##STR9## wherein R2 is a C6 -C18 hydrocarbyl group;
R3 is a C1 -C4 hydrocarbyl group;
each R4 is hydrogen, a C1 -C4 hydrocarbyl group, or a C2 -C3 alkylene oxide group, or mixtures thereof, containing from about 1 to about 10 alkylene oxide units; and
(b) from about 1% to about 50% by weight of an organic surfactant selected from the group consisting of anionic, cationic, nonionic, ampholytic, and zwitterionic surfactants, and mixtures thereof.
