  • Applications

    Sorbitan Diisostearate (CAS 68238-87-9) is a nonionic ester-based surfactant commonly used as an emulsifier and dispersing agent in cosmetics and personal care, helping form stable oil-in-water emulsions and providing slip in emollient formulations. It also functions as a surfactant and emulsifier in household cleaning products, improving wetting and cleansing performance. In coatings, inks, and related industrial formulations, it acts as a wetting agent and emulsifier to enhance pigment dispersion and film formation. In polymer and adhesive formulations, it can serve as a processing aid or compatibility-enhancing component to improve flow and texture. In agrochemical formulations, it is sometimes used as an emulsifier or adjuvant to improve dispersion of active ingredients.
