  • Applications

    Polyethylene glycol nonylphenyl ether sulfate ammonium salt (CAS 9051-57-4) is an anionic surfactant used as a detergent and emulsifier in a range of formulations. In real-world applications, it serves as: cleaning agents in household and industrial cleaners (detergents, dishwashing liquids, surface cleaners); surfactant/emulsifier in cosmetics and personal care products; wetting agent and emulsifier in coatings and inks; emulsifier and dispersant in polymer and plastics processing; surfactant in textile processing (scour, dyeing, finishing); additive in metalworking fluids and industrial degreasers. Use is subject to local regulations and formulation limits.
