What's polysorbate 65?

 

Polysorbate 65 is also known as polyoxyethylene sorbitan tristearate, dehydrated sorbitan tristearate polyoxyethylene ether, T-65 emulsifier.

 

Polysorbate 65 is produced in the addition reaction between sorbitan tristearate and ethylene oxide with sodium hydroxide as the catalyst.

 

Main applications:

It can be used as emulsifier, stabilizer, wetting agent, diffusion agent, permeability agent, etc.

It is mainly used as oil-in-water emulsifier for creams and lotion cosmetics, as well as thickening agent.

It can be used as wetting agent, paraffin inhibitor for oil field.

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...
