Amphoteric ester sulfonates

Abstract:

Disclosed are a variety of amphoteric ester sulfonates, including 3-(N, N-dimethyl-cocoylpropylammonio-1-yl)-2-hydroxypropanesulfonate. These amphoteric ester sulfonates can be advantageously prepared in high yield and purity by a two-step chemoenzymatic process, and have excellent surfactant properties.
