Abstract
A process is provided for making amphoteric surfactant compositions from substituted imidazolines whereby such substituted imidazolines are reacted with chloroacetate salts and then hydrolyzed to open the imidazoline ring and produce a solution which is substantially completely free from cyclic groups. The product solutions are highly foamable and have low skin irritation and low eye irritation characteristics.
