Polysorbate 81

 

Polysorbate 81, also known as polyoxyethylene (5) sorbitan monooleate, consists of sorbitol, ethylene oxide, and oleic acid. It has a molecular formula of C34H64O11. At room temperature, it is in the form of a pale-yellow orange oily liquid. It is an O/W emulsifier with an HLB value of 10.0. It is soluble in ethanol, ethyl acetate, and toluene; slightly soluble in mineral and vegetable oil. And it can be dispersed in water.

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

图片
  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...
