ABSTRACT:
A high polymeric organosiloxane cationic emulsion composition comprising (A) a polydiorganosiloxane of formula: HO—[R2SiO]n—H wherein R is an organic group and n is a number to give a viscosity of at least 300 Pa-s at 25° C., (B) a cationic surfactant of formula: Q3(CH3)N+·X−wherein Q is an organic group and X is halogen or carboxyl, and (C) water is fully stable. It is prepared by dispersing a corresponding organosiloxane and the cationic surfactant in water to form an emulsion, polymerizing in the presence of an alkali catalyst at 0-90° C. for 10-150 hours, and neutralizing with an acidic compound.
