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 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.

What is HLB value?

图片
  WHAT IS HLB ? 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. Huana  has been professionally concentrated on Sorbitan  Esters & Polysorbates since 1993, with decades of R&D and production experience.

Differences between polysorbate 20 and polysorbate 80

  W hat I s the D ifference between polysorbate 20 and 80   Synthetic Raw Materials Difference between  P olysorbate 20 80 Polysorbate 20 is a product of the polymerization reaction of sorbitan monolaurate and ethylene oxide, while polysorbate 80 is synthesized by the polymerization of sorbitan monooleate and ethylene oxide.   Application Difference between Polysorbate 20 and 80 P olysorbate 20 uses in cosmetics   is known as a non-ionic stain remover because it has relatively more hydrophilic groups (polyoxyethylene), which gives it a strong hydrophilicity property. Polysorbate 20 is usually used as an oil-in-water(O/W) type emulsifier and solubilizer.   Polysorbate 80 is one of the most common polysorbates. The   polysorbate 80 emulsifier   has significant resistance to electrolyte and strong hydrophilicity, which allow it to be widely used in liquid, semisolid and solid preparations. Polysorbate 80 is used as an oil-in-water(O/W) type emulsifie...
