Cetyl dimethicone

Cetyl dimethicone (CAS 191044-49-2) is a silicone-modified long-chain fatty alcohol used primarily as an emulsifier and skin-conditioning agent in cosmetic and personal care formulations.

By combining silicone fluidity with a cetyl hydrophobic tail, it enables stable water-in-silicone emulsions that conventional emulsifiers cannot readily achieve for industrial use.

Formulators and industrial buyers source it for its dual function in surface modification and moisture retention across multiple end-use markets including skin care and color cosmetics.

It stabilizes water-in-silicone emulsion systems in foundations, sunscreens, and moisturizers, delivering a lightweight, non-greasy skin feel for high-end consumer products.

Hair care formulators use it in conditioning treatments and serums to improve surface wetting and deposit silicone actives more uniformly along the hair shaft for better results.

In textile finishing, it functions as a softening and surface-modification agent, improving fabric hand and water repellency while enhancing the overall durability of the treated material.

Coating and sealant manufacturers incorporate it to enhance substrate wetting and compatibility between silicone matrices and polar components in various industrial applications.

Cetyl dimethicone is typically supplied as a clear to pale yellow viscous liquid available in cosmetic-grade specifications and technical grades for bulk procurement in drums or IBCs.
