DIMETHICONOL- ▸ Hair conditioning: Deposits a smooth film for shine, slip and detangling.
- ▸ Skin emollient: Softens and conditions in skin-care emulsions.
- ▸ Film former: Builds a water-repellent silicone film on hair and skin.
- ▸ Antifoam: Controls foam in formulation and process streams.
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Dimethiconol (CAS 31692-79-2) is a hydroxyl-terminated polydimethylsiloxane silicone fluid or gum. It is used in personal-care formulation as an emollient and conditioning agent for skin and hair, as a film former, and as an antifoaming agent.
Frequently Asked Questions
What is dimethiconol used for?
Dimethiconol (CAS 31692-79-2) is a hydroxyl-terminated polydimethylsiloxane silicone fluid or gum. It is used in personal-care formulation as an emollient and conditioning agent for hair and skin, as a film former, and as an antifoaming agent.
What is the difference between dimethiconol and dimethicone?
Both are polydimethylsiloxane silicones, but dimethiconol is hydroxyl-terminated (it carries -OH end groups), whereas dimethicone has methyl-terminated chains. The terminal hydroxyls give dimethiconol its higher-molecular-weight gum behavior and film-forming character used in conditioning.
Is dimethiconol water soluble?
No. Dimethiconol is a silicone fluid/gum and is not water soluble; it is used in oil phases and deposits a water-repellent film on hair and skin. Refer to the SDS for physical-property and handling data.
What is the CAS number and formula of dimethiconol?
Dimethiconol is identified by CAS 31692-79-2 with the repeat-unit formula reported as C2H8O2Si. Specify the target viscosity/molecular-weight grade when ordering, as it is supplied as both fluids and gums.
How is bulk dimethiconol supplied?
RawSource supplies dimethiconol in drums and totes to personal-care and silicone-blend manufacturers, with CoA and SDS per lot. Pricing is quote-based on grade, volume, and packaging; request a current bulk quote.
