C9-13 Isoparaffin
What is C9-13 Isoparaffin?
C9-13 Isoparaffin is a synthetic mixture of branched-chain saturated hydrocarbons, primarily alkanes with 9 to 13 carbon atoms, derived from petroleum refining processes and highly purified for cosmetic use. Commonly found in oil-in-water emulsions, cleansers, sunscreens, and makeup products, it serves as a non-polar solvent that dissolves oil-soluble ingredients and active compounds, facilitating their even distribution. As a viscosity controlling agent, it modifies product thickness, enhancing spreadability, stability, and sensory feel without adding greasiness. Its low volatility prevents rapid evaporation, ensuring consistent performance during application. In formulations, it helps suspend particles and maintain emulsion integrity, contributing to lightweight, non-tacky textures ideal for daily skincare routines.
