Carbinol (Hydroxyl) Terminated Polydimethylsiloxane CAS#67674-67-3
Basic Information
Hydroxyl
Carbinol-terminated polydimethylsiloxane is an amphiphilic organosilicon liquid combining siloxane and polyoxyethylene segments. This structure balances water and oil compatibility, provides strong surface activity and supports uniform dispersion of particulate or film-forming ingredients. As a silicone-glycol wetting agent, it lowers water surface tension and improves coating uniformity, particularly in spray formulations. It is also used as an intermediate for silicone–polyether copolymers and in coatings, textiles and cosmetic formulations.

Product Description of Carbinol (Hydroxyl) Terminated Polydimethylsiloxane CAS#67674-67-3
Alpha-[3-[1,3,3,3-tetramethyl-1-(trimethylsilyloxy)disiloxanyl]propyl-omega-hydroxypolyoxyethylene] (CAS 67674-67-3) is a special amphiphilic organosilicon compound with siloxane and polyoxyethylene segments. It is a colorless to pale yellow viscous liquid, and its molecular weight varies from 222.51 to 324.64 g/mol with the polyoxyethylene chain length.
Product Application of Carbinol (Hydroxyl) Terminated Polydimethylsiloxane CAS#67674-67-3
Carbinol-terminated polydimethylsiloxane is an efficient wetting agent. As a silicone glycol surfactant, it greatly reduces water surface tension even at a low concentration of about 0.1%. It optimizes particle size distribution and enables uniform coating of active ingredients and film-forming materials, mainly applied in spray formulations.
