Chemical Structure
Basic Info
Tween is a non-ionic family of amphiphilic surfactants. Polysorbate 80 (Tween) is one of the most commonly used surfactants in biopharmaceutical formulas. It can be used to prevent denaturation and aggregation of proteins, as well as surface adsorption and flocculation.
Tween 80, also known as polyoxyethylene monooleate dehydrated, is a mixture that consists primarily of sorbitol monooleate.
Tween 80, the most common surfactant used in biologics, is also used to stabilize proteins in many commercial therapeutic protein preparations. The following factors are responsible:
1) Tween 80 is biocompatible;
2）Tween 80 has a low toxicity.
3) Effective protein stabilization. Even in low concentrations, Tween 80 is sufficient to stabilize proteins.
Tween 80, a polyoxyethylene with excellent surface activity and emulsifying qualities.
The following are the properties of Tween 80:
Tween 80 has a yellowish brown color.
-Solubility : Easy to dissolve in water and many organic solvents
Stability: This product is stable and can be used in acidic or alkaline environments.
Tween 80 is mainly used for:
It is used as an emulsifier, stabilizer and in lotions, emulsions, and sprays.
-Used in biomedical and cell culture research
The Tween 80 Method
Tween 80 can be prepared primarily by esterification between sorbitol, stearic and stearic acids. This is followed by an epoxidation with a small amount of ethylene dioxide.
