Tween 85 Usage And Synthesis
Chemical PropertiesAmber liquid
UsesLonzest(R) STO-20 is a mid-range HLB, nonionic surfactant suggested for use in textile chemicals (lubricant, emulsifier), household products (o/w emulsifier) and cosmetic formulations (o/w emulsifier).
UsesTween 85 has been used in a study to assess the potential application of niosomes for the delivery of ammonium glycyrrhizinate for the treatment of inflammatory diseases.
UsesTween 85 is an emulsifier produced by reacting oleic acid with sorbitol to yield a product which is reacted with ethylene oxide. It is a nonionic, water-dispersible surface-active agent that is very soluble in water. It is also termed polysorbate 80. It is used in ice cream and frozen desserts for overrun and dryness; as a disperser of flavors and colors in pickles; and for volume and texture in baked goods. It is frequently used with monoand diglycerides at usage levels ranging from 0.05 to 0.10%.
Brand nameTween 85 (ICI Americas).
General DescriptionTween 85 is a polyoxyethylene sorbitan trioleate non-ionic surfactant.
