Tween-20（Cat No.:I010714）, also known as Polysorbate 20, is a nonionic surfactant and emulsifier with the molecular formula C26H50O10, widely used in pharmaceutical, cosmetic, and food industries. Derived from sorbitol and lauric acid, it appears as a viscous, water-soluble liquid. Tween-20 reduces surface tension and stabilizes emulsions, making it valuable in protein purification, cell lysis buffers, and immunoassays such as ELISA. It is also used in eye drops, vaccines, and skincare products. Known for its mildness and biocompatibility, Tween-20 is generally regarded as safe but should be used within concentration guidelines.
