Answer:Tween 80, or polysorbate 80, is a nonionic surfactant used for wetting, emulsification and solubilization.
Answer:This product is EMPROVE Essential grade with Ph Eur, JP and NF specifications.
Answer:The selected package contains 2.5 L of polysorbate 80.
Merck Tween 80, also known as polysorbate 80, is a nonionic surfactant in the EMPROVE Essential quality range for pharmaceutical and laboratory formulation workflows. The material is identified by CAS 9005-65-6 and complies with the stated Ph Eur, JP and NF grade requirements for this product family. The 2.5 L bottle format supports laboratory development and larger formulation operations that require a consistent surfactant supply. Polysorbate 80 is widely used as a wetting, solubilizing and emulsifying excipient in aqueous formulations; compatibility and concentration must be established for the individual formulation. It can also help minimize interfacial stresses in certain protein-containing preparations when selected and validated appropriately. The EMPROVE documentation program supports material qualification activities, while the lot-specific certificate provides applicable quality information. Avoid treating the surfactant as a sterilizing agent or as a substitute for a validated formulation process.
