• 소개 및 적용: Polysorbate 20, also known as Tween 20, is a hydrophilic nonionic surfactant commonly used as an emulsifier, dispersing agent, and solubilizer. It is formed by the ethoxylation of sorbitan and the addition of lauric acid, which is found mainly in coconut oil. Polysorbate 20 is widely used in various fields such as pharmaceutical, chemical, food, and textile industries due to its stability and relative non-toxicity. In biological techniques and sciences, it is added to buffers and reagents for immunohistochemistry, such as Western blots and ELISAs, to prevent non-specific antibody binding, decrease background staining, and enhance reagent spreading. It is also used as a wetting agent in flavored mouth drops, in oral or non-gastrointestinal suspensions, and in rubber balers in the elastomer industry. Additionally, Polysorbate 20 is used as a solubilizing agent of membrane proteins, a washing agent in Western blots and ELISAs, and an excipient to stabilize emulsions and suspensions in pharmaceutical chemistry. It is also used as a dispersing agent, stabilizer, and lubricator in various cosmetic products such as creams, salves, ointments, protective creams, balms, pomades, lipsticks, mascaras, and glosses.
