  • Applications

    PEG-3 Lauramide (CAS 26635-75-6) is commonly used as a nonionic surfactant and emulsifier in cosmetics and personal care products, aiding cleansing, conditioning, and stable emulsion formation in shampoos, cleansers, creams, and lotions. It is also employed in household and industrial cleaning formulations as a dispersing and surfactant additive to improve wetting, foaming, and cleaning performance. In coatings and inks, it acts as a surfactant/emulsifier to enhance flow, leveling, and pigment dispersion. In polymer and plastics processing, it may serve as a processing aid or lubricity-enhancing additive, promoting compatibility with other ingredients and reducing friction during processing.
