Sorbitan Tri Stearate (STS) / Emulsifier(s65)
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.

FAQ
—
What is the difference between polysorbates and sorbitan esters?
Polysorbates are ethoxylated sorbitan esters that are made by ethoxylation of sorbitol with different fatty acids. Polysorbates are hydrophilic, whereas sorbitan esters are lipophilic.
What is a water-in-oil (WO) emulsifier?
In water-in-oil emulsion, the hydrophilic parts of emulsifiers surround the water droplets and expose their lipophilic portions to the oil phase. This allows water droplets to suspend in oil environment.
What is sorbitan ester made of?
Sorbitan ester is composed of sorbitol-derived hexitol anhydrides aka sorbitans and various fatty acids (lauric acid, palmitic acid, stearic acid and oleic acid etc.).Fatty acids are attached to sorbitans through esterification reactions.
What is sorbitol? What is the difference between sorbitol and sorbitan?
Sorbitol is a sugar alcohol (crystalline hexahydric alcohol) that can be sourced from plants, such as comes and potatoes.When sorbitol undergoes a dehydration process,where one water molecule is removed, it creates an anhydride called sorbitan.
What is HLB value?
HLB value is the abbreviation for hydrophilic-lipophilic balance,it is the ratio between the hydrophilic portions and lipophilic portion of a surfactant It is represented by a number between 1 and 20. An HLB value less than 6 indicates that the surfactant favors W/O emulsion; an HLB value greater than 8 favors O/W emulsion. HLB values in between 7 and 9 indicate that the surfactants are good wetting agents.
What are the differences of the range of polysorbates?
The various polysorbates differs by the type of fatty acids and the number of fatty acids attached to the polyoxyethylene sorbitan portions of the molecules.Thus, each of the polysorbate has its own hydrophilicity/hipophilicity property and characteristic.
