Ethoxydiglycol
What is Ethoxydiglycol?
Ethoxydiglycol, chemically diethylene glycol monoethyl ether, is a synthetic, low-odor liquid derived from ethylene oxide and ethanol reactions. Widely used in skincare serums, toners, hair conditioners, and fragranced products, it excels as a solvent by dissolving lipophilic and hydrophilic actives for uniform formulations. As a humectant, it binds water to skin and hair surfaces, supporting hydration. It controls viscosity for optimal spreadability and stability, while solubilizing fragrances to maintain scent integrity without altering product feel. This multifunctional role enhances active delivery and sensory qualities across water- and oil-based systems.
