General Description
Sorbitan Tristearate is a non-ionic surfactant and emulsifying agent produced by the esterification of sorbitol with stearic acid. It is primarily used to stabilize water-in-oil emulsions and to enhance the structural integrity of oil-rich formulations. Due to its low HLB value, Sorbitan Tristearate is particularly effective in systems where controlled emulsification, viscosity build, and phase stability are required.
It is characterized by its excellent compatibility with oils, waxes, fatty esters, and lipophilic active ingredients. It contributes to improved texture, consistency, and shelf stability without affecting fragrance profiles or active performance. Its non-ionic nature ensures stability across a wide pH range and compatibility with other surfactants commonly used in personal care, pharmaceutical, and industrial formulations.
Sorbitan Tristearate is widely used in cosmetic and pharmaceutical creams, ointments, sunscreens, and makeup products, as well as in selected food and industrial applications where regulatory compliance permits. Its consistent performance, formulation flexibility, and processing stability make it a preferred emulsifier in applications demanding long-term product integrity and controlled rheology.
