Dimethiconol

Dimethiconol (CAS 31692-79-2) is a hydroxyl-terminated polydimethylsiloxane; a surface modifier and conditioning agent.

Where is Dimethiconol used?

• Hair care and skin formulations: deposits a uniform silicone film
• Conditioners, serums and leave-on treatments: reduces friction, improves combability and enhances shine
• Textile and leather finishing: soft hand feel and water repellency
• Automotive and industrial coatings: surface leveling and wetting agent that reduces surface tension to prevent cratering
• Sealants and elastomers: reactive intermediate or plasticizer whose terminal hydroxyl groups enable crosslinking with silicone networks

Commercial specifications

• Viscosity grades from low to ultra-high molecular weight
