1,2-Hexanediol
What is 1,2-Hexanediol?
1,2-Hexanediol is a synthetic six-carbon diol alcohol, chemically known as hexane-1,2-diol, derived from petrochemical sources. In cosmetics, it belongs to the category of multifunctional glycols, primarily functioning as a solvent to dissolve and blend other ingredients, aiding in viscosity control and even distribution of actives in water- and oil-based formulations. It also acts as a humectant, drawing moisture to the skin's surface, and serves as a preservative booster by disrupting microbial cell membranes, enhancing formula stability. This colorless, odorless liquid integrates seamlessly into serums, creams, and cleansers, contributing to smooth textures and prolonged shelf life without compromising skin feel. Regulatory bodies like the Cosmetic Ingredient Review affirm its role in rinse-off and leave-on products at typical use levels.
