Polysorbate 61

 Polysorbate 61, also known as polyoxyethylene (4) sorbitan monostearate consists of sorbitol, ethylene oxide, and stearic acid. It has a molecular formula of C32H62O10. At room temperature, it is in the form of pale-yellow to amber-colored oily liquid or paste. It is an O/W emulsifier with an HLB value of 9.6. It is soluble in ethanol, ethyl acetate, and toluene. It can also be dispersed in water.

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.). Polyoxyethylene sorbitan fatty acid ester is attached to sorbitans through esterification reactions.

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.

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...
