  • Applications

    Bis(2-hydroxyethyl)methyloleylammonium chloride (CAS 18448-65-2) is a quaternary ammonium salt with a cationic surfactant character, featuring a hydrophilic head and a long oleyl hydrophobic tail, used as a surface-active and emulsifying/conditioning agent in formulations. Real-world applications include cosmetics and personal care as a conditioning surfactant for hair and skin; household cleaning products as a wetting and detergency aid; textile processing as a fabric softener and surface-softening agent; coatings and inks formulations as a surfactant and dispersant to improve wetting and film formation; and use in polymers/plastics processing or adhesives/paints as a processing aid or surface-active additive where controlled surface activity is desired.
