Isocetyl alcohol

Isocetyl alcohol (CAS 36311-34-9) is a branched-chain fatty alcohol used primarily in personal care and pharmaceutical formulations as an emollient, emulsifier, and texture modifier. Its branched structure prevents the waxy, heavy feel associated with straight-chain fatty alcohols, making it a preferred choice where a lightweight, non-greasy skin feel is the formulation target.

In skincare and color cosmetics, it functions as an emollient and rheology modifier, contributing to spreadability and a smooth after-feel in creams, lotions, and foundations. Hair care formulators incorporate it into conditioners and styling products where it aids in detangling and improves product slip without excessive buildup for the end user.

Pharmaceutical topical formulations use it as a carrier and co-emulsifier in ointments and creams, supporting active ingredient delivery across the skin barrier effectively. It also serves as a solvent and dispersant in pigment-based systems, improving pigment wetting and stability in color cosmetic manufacturing and various industrial applications.

Isocetyl alcohol is supplied as a clear to pale yellow liquid at room temperature. It is available in cosmetic-grade and pharmaceutical-grade specifications for diverse needs. The latter typically conforms to relevant pharmacopeial standards. Bulk supply is standard in drums and IBCs, with technical-grade material also available for industrial applications.
