  • Applications

    Acetic acid, 2-[2-(2-methoxymethylethoxy)methylethoxy]-, sodium salt (1:1) (CAS 165038-56-2) is typically used as an anionic surfactant and dispersing agent in a range of industrial formulations. In household and industrial cleaning products, it provides wetting and emulsifying action to improve soil removal and phase stability. In cosmetics and personal care, it can serve as a surfactant and fragrance solubilizer, aiding emulsions and product texture. In coatings and inks, it functions as a dispersant and wetting agent to enhance pigment dispersion and film formation. In polymer processing and plastics, it can act as a processing aid or stabilizer, improving processing characteristics and emulsion stability for polymer blends. In agricultural formulations, it may be used as an adjuvant to improve spray coverage and formulation stability of pesticides or formulated products. It can also be used as a solubilizer for fragrance or other actives in perfumery and flavor applications, subject to local regulations and formulation limits.
