Silanol vs. Carbinol

Posted: May 22, 2007

Tony O’Lenick explores the differences between a silanol and a carbinol.

Silanol and carbinol both refer to a class of silicone compounds that have hydroxyl groups (OH). Both types of compound are more polar than silicone fluids (dimethicone). Silanol compounds have an Si-OH group. Prior to 1999, they were referred to as dimethiconol. They are found commonly in hair gloss formulations.

Carbinol compounds are a class of polar silicone in which the hydroxyl group is attached to a carbon atom. They are available in three types of molecules. The most common is the comb or rake structure. In this type of structure, the organofunctionality is on an internal position.
