In the middle of the 20 century carboxymethylated fatty (poly)amine derivatives gain currency as relatively mild germicidal surfactants [56, 57, 103]. They are derived from linear amines, such as the alkylamidoethylenediamine, and sodium chloroacetate, as presented below ... 

Similar to the carboxymethylation of tertiary fatty amines to alkyl betaines, the pH value in the carboxymethylation of alkylamidoamines needs to be controlled and kept between 7.5 to 10.5 (9). If the pH of the reaction medium is below approximately 7.5, the carboxymethylation will slow down due to the increasing protonation of the amine, while the undesired hydrolysis of chloroacetate will result in large amounts of glycolic acid. When the pH exceeds approximately 10.5, hydrolysis of the amide group may occur, which leads to undesired high contents of fatty acids and carboxymethylated amine derivatives, and finally to decomposition of the final product.

Amphoteric surfactants based on carboxymethylation of fatty imidazolines or fatty imido-amines generated by their hydrolysis are well established as extremely mild surfactants [9].
