Mechanism of Action
On the skin, Isohexadecane acts as a non-occlusive emollient, delivering a smooth and soft sensation while minimizing transepidermal water loss by forming a delicate protective film. Its large molecular structure prevents significant skin penetration, ensuring surface-level benefits without hindering natural skin functions. As a solvent, it facilitates the even dissolution and distribution of other active ingredients and pigments. Furthermore, it significantly improves product aesthetics by enhancing spreadability and slip, contributing to a desirable dry-touch finish.

Formulation
Stability
Isohexadecane exhibits high stability across a wide pH spectrum, from acidic to slightly alkaline conditions. It is resistant to oxidation and degradation during various processing steps, including heating, cooling, and emulsification, and remains inert when combined with other ingredients.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has determined Isohexadecane to be safe for use in cosmetic applications. While highly concentrated forms may carry irritation warnings, its inclusion in cosmetic formulations rarely triggers allergic reactions or skin irritation. The FDA also acknowledges similar synthetic isoparaffin hydrocarbons in certain food-related applications.
