  • Applications

    PEG-3 Oleyl Ether Carboxylic Acid is commonly used as a nonionic surfactant and emulsifier in cosmetic and personal care formulations, aiding solubilization of fragrances and active ingredients and contributing to a light, creamy texture in creams or lotions. It is also employed in household cleaning products as a wetting and emulsifying agent to improve cleaning performance and formulation stability. In coatings and inks, it serves as a surfactant for wetting and dispersion, helping pigment dispersion and surface leveling. In polymer and plastics processing, it can act as a dispersant or processing aid, assisting emulsion stability and compatibility of additives. In industrial manufacturing, it is used as a versatile surfactant and formulation additive across various products, and in some pharmaceutical contexts it may be evaluated as a solubilizer or emulsifier, depending on the formulation and regulatory constraints.
