Abstract: Imadazoline-based amphoacetates of higher purity, containing essentially negligible amounts of unalkylated amido amines, lower amounts of glycolic acid salts and monochloroacetate salts, superior to currently available conventional amphoacetates, are provided. This is demonstrated by their improved surface-active properties. Lower inherent irritation properties may be expected due to improved purity.The higher purity amphoacetates can be obtained via processes utilizing precise pH control during the reaction of imidazoline, or its open-chain derivatives, with alkylating agents, e.g. sodium monochloroacetate. The pH can be controlled by adding the base slowly or automatically in response to a pH metering device to maintain a constant pH, or by a series of staged additions which are calculated to maintain pH within a stated range. The reaction may also be carried out by conducting the initial hydrolysis of the imidazoline ring structure, followed by alkylation.
