HYDROLYSIS RESISTANT TRISILOXANE IONIC SURFACTANTS MODIFIED WITH ORGANIC GROUPS Russian patent published in 2014 - IPC C08G77/38 C08L83/08 A01N55/10 B01F17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to siloxane surfactant compositions. Disclosed is a surfactant composition which contains siloxane, having the formula: M¹DM², where M¹=(R¹)(R²)(R³)SiO_1/2; M²=(R⁴)(R⁵)(R⁶)SiO_1/2 and D=(R⁷)(Z)SiO_2/2, where each of the substitutes R¹, R², R³, R⁴, R⁵, R⁶ and R⁷ is independently selected from a group consisting of monovalent hydrocarbon radicals containing 1-4 carbon atoms, aryl and a hydrocarbon group containing 4-9 carbons and containing an aryl group; Z is a side hydrophilic ionic group selected from a group consisting of R⁸-R^A, R⁹-R^C and R¹⁰-R^Z, where R^A is an anionic substitute, R^C is a cationic substitute or R^Z is zwitterionic substitute on group D. Also disclosed are aqueous and non-aqueous emulsions based on said surfactant composition.

EFFECT: said surfactant composition is resistant to hydrolysis in both a basic and an acidic medium.
