  • Applications

    Disodium steariminodipropionate, CAS 20716-30-7, is commonly employed as an anionic surfactant and emulsifier in cosmetics and personal care (such as cleansers and shampoos) and in household cleaning products, providing enhanced cleaning performance, emulsification, and foam stability. In industrial formulations, it often acts as a surfactant and emulsion stabilizer for oil–water systems, aiding dispersion of solids and improving formulation uniformity. In coatings and inks, it may function as a processing aid or dispersant to improve dispersion and color stability. In polymers/plastics, it can serve as a processing aid or compatibilizer in certain polymer blends. It may also be considered as an adjuvant in agricultural formulations to assist wetting and deposition of pesticides, subject to local regulations.
