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 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 an .alpha.-monoepoxide such as propylene oxide, or higher .alpha.-epoxides. The said diesters have utility as surfactants, such as detergents and emulsifiers.
