  • Applications

    Disodium lauriminobishydroxypropylsulfonate (CAS 4055-91-8) is an anionic surfactant with a lauryl-type hydrophobic tail, typically used as a surface-active agent and emulsifier in a range of formulations; common applications include household and industrial cleaning products (detergents and cleaners); cosmetics and personal care (shampoos, body washes) where it acts as a foaming and emulsifying agent; coatings and inks (emulsification, wetting and dispersing within coatings and printing formulations); and polymers/plastics processing (as a processing aid and to improve dispersion and leveling in polymer formulations). It may also serve as a surfactant additive in material systems and help stabilize emulsions.
