Sorbitan tristearate is a nonionic surfactant and emulsifier derived from the esterification of sorbitol with stearic acid. It appears as a waxy solid and is primarily used to stabilize oil-in-water and water-in-oil emulsions. This ingredient enhances the smooth texture and consistency of creams, lotions, and other formulations. Due to its mild nature and multifunctionality, it finds wide applications in cosmetics, pharmaceuticals, and food industries.
