Isohexadecane
What is Isohexadecane?
Isohexadecane is a branched-chain hydrocarbon, known as an isoparaffin, produced synthetically or from refined petroleum fractions. In skincare products, it falls under volatile emollients and solvents, prized for its clear, odorless profile and quick-drying nature. It works by mimicking skin's natural oils to smooth surface irregularities, while its solvent properties dissolve lipophilic ingredients, ensuring even blending and controlled release. This enables silky textures in lotions, primers, and oil-free moisturizers, where it minimizes tackiness and boosts slip without heaviness. Its stability across pH levels supports diverse formulations, from water-in-oil emulsions to lightweight sprays, enhancing overall sensory appeal and ingredient compatibility without altering skin's barrier function.
