ABSTRACT:
Unsymmetrical sulfosuccinate diesters in which one carboxyl group of the sulfosuccinate is esterified with an alcohol, for instance, a C.sub.8 -C.sub.12 aliphatic monohydric alcohol such as octyl or dodecyl alcohol, or with an ethoxylated or propoxylated alkyl phenol, and in which the other carboxyl group is esterified by reaction with ethylene oxide, and method of preparation of such diesters. The said diesters have utility as surfactants, such as detergents and emulsifiers.
