  What is polysorbate 85? Polysorbate 85 is also known as polyoxyethylene 20 sorbitan trioleate, consists of sorbitol, ethylene oxide, and oleic acid. It has a molecular formula of C100H188O28. At room temperature, it is in the form of a pale-yellow to orange oily liquid. It is an O/W emulsifier with an HLB value of 11.0. It is soluble in ethanol, ethyl acetate, and acetone; it is also soluble in most mineral and vegetable oil. And it can disperse in water. In crude oil production, polysorbate 85 acts as an emulsifier, paraffin inhibitor.   CAS NO.: 9005-70-3   MOLECULAR FORMULA: C100H188O28   Advantages of Polysorbate 85   Our polysorbat 85  is used an emulsifier, foaming agent, lubricant, solubilizer, antistatic agent, a dispersing agent in industrial product formulations   Can be used in industry   Instructions on Use and Storage Storage Store in a cool, dry place in tightly sealed packages, away from heat and light   Transportation Transp...

  Polysorbate 80, also known as polyoxyethylene sorbitan monooleate, consists of sorbitol, ethylene oxide, and oleic acid. It has a molecular formula of C64H124O26. At room temperature, it is in the form of pale-yellow to amber oily liquid. It is an O/W emulsifier with a   polysorbate 80 HLB value   of 15.0. It is soluble in water, ethanol, ethyl acetate, and toluene. Polyethylene glycol sorbitan  monooleate is a surfactant with numerous applications in food, pharmaceutical, and cosmetics; other than that, it can also use as an emulsifier for culture medium to reduce the surface tension of the medium, which enhances the growth of cells. Polyethylene sorbitan monooleate is also widely used in industrial productions such as use as a wetting agent and dispersant for photographic film making; as a stabilizer and foaming agent for polyurethane foaming plastic.   Huana  is one of the leading   polysorbate 80 suppliers and   manufacturers in China, feel ...

  Application of Polysorbate 80 in Preparation of Test Product 1. What is polysorbate 80? Polysorbate 80, the chemical name is polyoxyethylene 20 sorbitan monooleate, is a non-ionic surfactant, has significant adaptability to different pH, and is relatively stable when coexisting with high-concentration electrolytes. The water-lipophilic balance value (HLB value) is 15. It has strong hydrophilicity and is miscible with water, methanol, ethanol, chloroform and ethyl acetate. It is widely used in injections and oral preparations as O/W (water oil-in-oil) type emulsifier, solubilizer, wetting agent.   Studies have shown that when hlb polysorbate 80  reaches a certain critical micelle concentration, the hydrophobic parts of its molecules attract each other and combine to form micelles. The formed spheroids, the solubilized substances, combine with the micelles in different ways, thereby increasing the dissolution of the drug components, but the solubilization effect is differ...
