A detergent composition comprising:
- (a) from about 0.005% to about 99% by weight of an alpha-substituted compound having the formula:
- ##STR9## wherein R.sup.2 is a C.sub.6 -C.sub.18 hydrocarbyl group;
- R.sup.3 is a C.sub.1 -C.sub.4 hydrocarbyl group;
- each R.sup.4 is hydrogen, a C.sub.1 -C.sub.4 hydrocarbyl group, or a C.sub.2 -C.sub.3 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.
