Isohexadecene

What is Isohexadecene?

Isohexadecene is a synthetic branched-chain alkene hydrocarbon featuring 16 carbon atoms and a double bond, derived from petrochemical processes. It appears as a clear, colorless, low-viscosity liquid. Primarily categorized as an emollient in cosmetics, it features in moisturizers, serums, lotions, and hair care products. In formulations, it softens and smooths skin by creating a breathable film that limits moisture evaporation, while its slippery nature enhances spreadability and reduces tackiness. This ingredient blends well with esters and silicones, stabilizing emulsions and boosting sensory qualities like silkiness. Its chemical stability prevents rancidity, supporting long shelf life in anhydrous and aqueous systems alike.
