1 A mild and new type of amphoteric surfactant that has more advantages compared to carboxylic betaine such as alkyl and propyl groups. 2 It is free of chloroacetic acid impurities, has low inorganic salt content, and has low irritation. 3 Strong resistance to hard water and better resistance to calcium soap deposition. 4 It can be widely compatible with cationic, anionic, and non ionic surfactants, and can be compound with other surfactants to have good synergistic effects and reduce the irritation generated by traditional surfactants. 5 It can improve the foaming power to produce delicate, stable and rich foam, has high thickening performance, good salt resistance and no deterioration, thinning and layering due to low temperature.
