C13-15 Alkane

What is C13-15 Alkane?

C13-15 Alkane consists of branched and linear hydrocarbons with 13 to 15 carbon atoms in their chains. It originates from processes like hydrogenation of plant-derived oils or gas-to-liquid conversion from natural gas, offering a sustainable option compared to older mineral oils. Primarily used in leave-on skincare such as creams, lotions, and serums, it functions as an emollient and solvent. In formulations, it dissolves oil-soluble actives, stabilizes emulsions, and controls product viscosity for better application. Its volatile nature allows quick evaporation, leaving a dry, velvety finish that enhances penetration of other components while minimizing tackiness or heaviness on skin surfaces.
