C9-10 ALKANE/CYCLOALKANE.

Valuable CAS 64742-49-0 / SOLVENT

A sophisticated, high-volatility hydrocarbon mixture that serves as a weightless alternative to traditional silicones. It provides an exceptionally smooth application experience, allowing formulas to glide across the skin before evaporating to leave a silky, non-greasy finish.

Solvent Emollient Texture Enhancer Carrier

Science

This ingredient functions as both a volatile solvent and a light emollient. Upon application, it ensures the uniform distribution of active ingredients and pigments across the skin's surface; as it evaporates, it creates a breathable, micro-thin occlusive layer that helps lock in moisture without a heavy or occlusive feel.
