  • Applications

    PEG-3 oleamide (CAS 26027-37-2) is an amphiphilic fatty amide in which a short polyethylene glycol (PEG-3) chain is attached, and it is commonly used as a surfactant and lubricant in various formulations. In cosmetics and personal care, it serves as an emulsifier and conditioning agent to improve smoothness and feel on skin and hair. In polymers and coatings, it acts as a slip agent and processing additive to reduce friction and facilitate handling during extrusion or molding. In coatings, inks, and cleaning formulations, it can function as a surfactant and humectant to improve dispersion and leveling of coatings or cleaning performance. Its use is subject to local regulations and formulation limits.
