C9-12 Alkane
What is C9-12 Alkane?
C9-12 Alkane refers to a blend of branched hydrocarbons featuring carbon chains of 9 to 12 atoms, commonly derived from renewable plant materials such as sugarcane via fermentation processes. In cosmetic formulations, it acts primarily as a solvent and emollient, especially in lightweight, anhydrous, or emulsion-based products like serums, primers, and sunscreens. It effectively dissolves oil-soluble components, controls product viscosity, and facilitates even distribution on the skin. Upon application, its volatile nature allows rapid evaporation, imparting a smooth, non-oily finish while enhancing the delivery of active ingredients. This makes it a popular eco-friendly substitute for traditional silicones or mineral oils, contributing to breathable textures in modern clean beauty products without leaving residue.
