C10-13 ALKANE.

Valuable CAS 129813-66-7 / SOLVENT

A lightweight hydrocarbon emollient that delivers silicone-like spreadability without the weight of traditional oils. This saturated alkane chain provides excellent sensory enhancement, creating a quick-dry, non-greasy finish that works exceptionally well in modern formulations requiring elegant texture.

emollient solvent texture enhancer

Science

Forms a thin, breathable film on the skin surface by filling intercellular spaces, providing emolliency while maintaining low occlusion. Its semi-volatile properties allow for rapid evaporation, leaving behind smoothness without residual heaviness or tackiness.
