Sorbitan Tristearate (CAS 26658-19-5) is a non-ionic surfactant and emulsifier produced by the esterification of sorbitol with stearic acid, supplied as white to off-white beads or a tan-colored waxy solid, and used as a water-in-oil emulsifier in confectionery, cosmetics and industrial coatings. This Food Grade/Technical Grade material is a powerful W/O (water-in-oil) emulsifier. It is particularly valued in the food industry for its ability to prevent fat bloom in chocolate and cocoa butter products. In cosmetics, it provides structural stability to sticks and thick creams. It is lipophilic (low HLB value), making it an ideal co-emulsifier for creating stable, rich emulsions in various sectors.
