Ethyl Hexanediol

What is Ethyl Hexanediol?

Ethyl hexanediol, chemically 2-ethylhexane-1,3-diol, is a synthetic aliphatic diol produced from petrochemical feedstocks. It belongs to the category of glycols used in cosmetic formulations such as lotions, serums, and cleansers. As a solvent, it effectively dissolves both polar and non-polar substances, enabling stable emulsions and controlling product thickness and drying speed for smoother application. In its role as a fragrance ingredient, it helps solubilize essential oils and perfumes while masking off-notes from raw materials, contributing to a pleasant user experience. This clear, colorless liquid has low viscosity, promoting even spreading and quick penetration into the skin without greasiness. Its versatility makes it common in water-based and anhydrous systems, supporting overall formula integrity without altering texture significantly.
