ISOHEXADECENE.

Valuable CAS 85909-49-5 / SOLVENT

Isohexadecene is a lightweight, non-greasy hydrocarbon solvent and emollient that significantly enhances product texture and spreadability. It creates a smooth, silky skin feel while forming a protective, non-occlusive barrier to help retain moisture. Notably, it evaporates without residue, contributing to a dry-touch finish.

Science

Isohexadecene primarily functions as an emollient, effectively softening and soothing the skin by creating a protective barrier that helps lock in moisture without leaving a greasy sensation. Its solvent properties are crucial for dissolving other ingredients and ensuring uniform dispersion of pigments and active compounds within formulations. Furthermore, it acts as a texture enhancer, providing excellent slip and spreadability, and its volatile nature allows for a fast-absorbing, dry-touch finish, making it ideal for delivering active ingredients and improving the longevity of long-wear products.

Safety

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded Isohexadecene is safe for cosmetic use, noting it is non-genotoxic and showed no adverse reproductive or developmental toxicity. Furthermore, kidney effects observed in male rats were deemed not relevant to human exposure. The FDA also permits synthetic isoparaffin petroleum hydrocarbons, including Isohexadecene, for specific food applications, reinforcing its established safety profile with a low risk of skin irritation or sensitization.
