Isododecane

Isododecane is a branched-chain volatile hydrocarbon solvent derived from petroleum refining. It's highly valued in cosmetic formulations for its exceptional volatility, which allows it to evaporate quickly from skin without leaving a greasy residue, making it ideal for lightweight, fast-drying products like primers, foundations, and antiperspirants. Formulators choose it for its excellent spreading properties, ability to dissolve and carry pigments and actives, and its capacity to reduce the tackiness of other ingredients while providing a silky, non-oily skin feel.
