  • Applications

    2,3-Dihydroxypropyl 2,2,3,3,4,4,5,5,6-nonakis(2,3-dihydroxypropyl)-16-methylheptadecanoate, CAS 133738-23-5, is a polyglycerol ester of a fatty acid. In practice, it is used as a nonionic surfactant and emulsifier in cosmetic and personal care formulations, and may serve as an emollient, humectant, or viscosity-modifying additive. It also functions as a surfactant/emulsifier in household cleaning products to improve wetting and dispersion of active ingredients. Due to its polyol headgroup, it can act as a plasticizer or processing aid in polymer and coating systems, including paints, coatings, and inks. In agriculture, it may be evaluated as an emulsifier or dispersing adjuvant for pesticide formulations. These applications depend on local regulations and formulation limits.
