Sorbitan Tristearate

Name: Sorbitan Tristearate
Brand: Guangdong Huana Chemistry Co., Ltd.

Sorbitan tristearate, also known as STS, is synthesized by the esterification of sorbitan with stearic acid. It has a molecular formula of C₆₀H₁₁₂O₈. At room temperature, it is in the form of a white to yellow granular solid. It has an HLB value of 2.1, which is fairly lipophilic. As a food additive, sorbitan tristearate can reduce the turbidity of vegetable oil containing high saturated fatty acids. It can also improve the fat crystal structure and stability in chocolate and margarine. In addition, it acts as an emulsifier in the cosmetic industry and as a lubricant in the textile industry.
