  1. W hat I s P olysorbate U sed F or ? Polyoxyethylene (20) sorbitan monolaurate (aka. polysorbate 20) and polyoxyethylene (20) sorbitan monooleate (aka. Polysorbate 80) derived from sorbitan monolaurate and sorbitan  monooleate through fatty acids esterification.   They are lipophilic nonionic surfactants that can be used in pharmaceutical excipients formulations to prevent protein denaturation, aggregation, surface absorption and flocculation during melting process. 2. The characteristics of polysorbates As a protein stabilizer, polysorbates can be degraded through oxidation and hydrolysis pathways, where the hydrolysis pathway is chemically induced or enzymatically catalyzed. Polysorbate 80 uses in pharmaceuticals and polysorbate 20 uses in pharmaceuticals are normally protein stabilizers in most commercial therapeutic protein formulations. This is because of the following characteristics of polysorbates: (1) Biocompatibility; (2) Low toxicity; (3) Effective protein ...

  1. What is a non ionic emulsifier ? Emulsifier is a kind of surfactant that stabilizes emulsions.   The function of an emulsifier is when it is dispersed on the surface of a dispersed substance, a thin film or electric double layer is formed, which can make the dispersed phase carry a charge; that can prevent small droplets of the dispersed phase from coagulating, thereby creating a stable emulsion. For example, add a certain amount of surfactant emulsifier to solid pesticide solid or liquid crude oil, then dissolve them in an organic solvent, and mix them evenly to make a transparent liquid called emulsifiable concentrate. Non-ionic surfactant is a common emulsifier. N atural non ionic surfactant   with higher HLB values are more suitable for preparing O/W emulsifiers; whereas ones with lower HLB values are more suitable for preparing W/O emulsifiers. Natural oil water emulsifiers are mostly hydrophilic gums, which can improve the viscosity of continuous phase and incr...

  Many consumers may notice some cosmetics contain a kind of chemical substance called "polysorbate 80", but they do not know the effect and function of this substance and would like to know whether the product containing polysorbate 80 skin care    is good or not.   Polysorbate 80 in cosmetics    is a yellow viscous liquid mainly used as the  surfactant and emulsifier in cosmetics and skin care products. As for polysorbate   80  emulsifier, polysorbate for skin   is relatively safe non-toxic chemical. It can be used by pregnant women, and it is non-acnegenic.If you want to know more about what products contain polysorbate 80, please visit our website.
