  • Applications

    poly(oxy-1,2-ethanediyl), alpha-dodecyl-omega-hydroxy-, phosphate, sodium salt (CAS number: 42612-52-2) is an anionic phosphate surfactant based on a polyethylene glycol chain with a dodecyl tail and a sodium phosphate head; in practical industry it is used as a surfactant and emulsifier in household cleaning products; it is also employed as an emulsifier and wetting agent in cosmetics and personal care; in paints and coatings, as well as inks, it helps with dispersion and compatibility of polymer or pigment systems; in polymer and plastics processing it can act as a dispersion stabilizer and emulsifier to improve emulsion stability; and in agriculture it may be evaluated as a surfactant adjuvant to improve spray coverage and deposition on plant surfaces.
