What type of tween 80 is used in docetaxel injection?

In docetaxel injections, the type of Tween 80 (Polysorbate 80) used is typically a pharmaceutical-grade form. This non-ionic surfactant acts as a solubilizing agent, helping to enhance the solubility and stability of the docetaxel drug in the formulation. The use of Tween 80 is crucial for achieving the desired concentration and bioavailability of docetaxel in intravenous injections.
