Sorbitan Tristearate

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 tri
stearate 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.
