Products Description of Carbinol (Hydroxyl) Terminated Polydimethylsiloxane CAS#67674-67-3
Alpha-[3-[1,3,3,3-tetramethyl-1-(trimethylsilyloxy)disiloxanyl]propyl-omega-hydroxypolyoxyethylene] is a specialized organosilicon compound that contains both siloxane and polyoxyethylene segments. As an amphiphilic molecule (CAS 67674-67-3), it usually presents as a colorless to pale yellow viscous liquid, with a molecular weight ranging from 222.51 to 324.64 g/mol—this variation depends on the length of its polyoxyethylene chain.
Its unique structure integrates the hydrophobic properties of heptamethyltrisiloxane and the hydrophilic characteristics of polyoxyethylene, which makes it useful as a surfactant and emulsifier in fields like cosmetics, coatings, and textiles. The compound also exhibits excellent surface activity, thermal stability, and compatibility with organic matrices, often acting as a key intermediate in the synthesis of silicone-polyether copolymers. Commercial grades of this compound typically have a purity of 98-99% and are supplied in sealed containers to avoid moisture absorption.

Product Application of Carbinol (Hydroxyl) Terminated Polydimethylsiloxane CAS#67674-67-3
Carbinol (Hydroxyl) Terminated Polydimethylsiloxane functions as a wetting agent. As a silicone glycol surfactant, it can reduce the surface tension of water even at a low concentration of 0.1%. It also improves particle size distribution and enables uniform coating of active ingredients or film formers, and is primarily applied in spray products.
