Isododecane
What is Isododecane?
Isododecane is a synthetic branched-chain alkane (C12H26) produced via petrochemical refinement and distillation for high purity. This clear, colorless, low-odor liquid serves mainly as a solvent and emollient in cosmetics like foundations, primers, dry shampoos, and cleansing oils. It dissolves oils, waxes, pigments, and scents efficiently, enabling stable, lightweight formulas. Its ultra-low viscosity and fast volatility allow quick-drying application, leaving no oily residue while providing initial slip for smooth blending. In anhydrous systems, it controls thickness and enhances spray fine mist. As an emollient, it mimics sebum to temporarily fill skin crevices, promoting even texture without penetration or hydration claims.
