Hexylene Glycol (CAS 107-41-5) is a multifunctional oxygenated glycol solvent supplied in Cosmetic Grade and Technical Grade, appearing as a clear, slightly viscous liquid with both hydrophilic and lipophilic character, and it is used as a coupling agent, viscosity modifier and humectant in cosmetics, water-borne coatings and hydraulic fluids. It acts as an exceptional coupling agent and viscosity modifier in aqueous systems. This clear liquid is characterized by its low volatility and high solvency for a variety of resins and oils. It improves the freeze-thaw stability of formulations and enhances the skin-feel of cosmetic products. It provides superior wetting and helps prevent the drying out of finished products during storage.
