Usage

Uses

Different sources of media describe the Uses of 9005-70-3 differently. You can refer to the following data:
1. Tween 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%.
2. Tween 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.
3. Lonzest(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).
