  • Applications

    Sorbitan, monoisohexadecanoate (CAS 97635-38-6) is commonly used as a nonionic emulsifier and surfactant in cosmetic and personal-care formulations, helping stabilize oil-in-water and water-in-oil emulsions and improving texture. It may also serve as an emulsifier and processing aid in household cleaning products and detergents, where it enhances wetting, dispersion, and surfactant performance. In coatings and inks, it acts as a surface-active additive that improves pigment dispersion and formulation stability. In polymer processing, it can function as a plasticizer or lubricant additive to aid melt processing and modify rheology. In pharmaceutical formulations, it may be employed as an excipient or solubilizing agent to stabilize emulsions and improve drug delivery characteristics. Subject to local regulations and formulation limits.
