Betaine surfactants It is generated by the response of fatty tertiary amines and sodium chloroacetate, consisting of cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the very first three and is currently the primary surfactant in child hair shampoo. In 1940, the American DuPont Firm invented and used this … Read More “Betaine surfactants Alkyl C12-14 hydroxypropyl sulfobetaine” »
