application of zwitterionic silicone surfactants in daily chemical industry 4-cosmetic silicone oil manufacturer

polyetherolamine modified silicone oil was first synthesized by reacting diethanolamine with epoxy modified silicone oil, and then reacted with sodium chloroacetate or sodium 2-hydroxy-3-chloropropyl phosphate to prepare carboxybetaine type (pbps) and phosphoric acid respectively. ester betaine type (ppbps) silicone amphoteric surfactant was studied, and the surface activity of two betaine silicone surfactants was studied. it was found that the critical micelle concentrations of pbps and ppbps were 0.3 g/l and 0.6 g respectively. /l, the surface tension at cmc is 25.93 mn/m and 26.13 mn/m respectively, the hlb value range is greater than 13 and between 10 ~ 13 respectively, and it is found that it has good emulsifying properties, foaming properties and antistatic properties.
