CAS 9005-65-6 Nonionic Surfactant And Emulsifier Polysorbate 80 Tween 80



Tween 80, also known by its chemical name Polysorbate 80, has the CAS number 9005-65-6. Here's a description, specification, and application of Tween 80:



Tween 80 is a nonionic surfactant and emulsifier that belongs to the polysorbate family. It is a yellowish to amber-colored viscous liquid at room temperature. Tween 80 is composed of a mixture of esters of sorbitol and fatty acids, primarily oleic acid, with a variable number of ethylene oxide units attached to the sorbitol backbone. This structure gives it excellent emulsifying, solubilizing, and dispersing properties.
