聚山梨醇酯类是一大类非离子表面活性剂，具有乳化、扩散、增溶、稳定等作用。在制药、日化、食品、纺织等工业中，广泛用作乳化剂、分散剂、增溶剂、稳定剂等。作为乳化剂高浓度电解质和pH值的改变对其乳化能力影响很小，是一大类优良的油/水型乳化剂。在制备油/水型乳化剂时，常与脱水山梨醇酯类合并使用，乳剂的稳定性更好。改变与其合用的乳化剂类型和用量，可以制得水/油型或油/水型的不同质地、不同稠度的乳剂、乳膏剂。由于对矿物油、植物油、动物油脂等各种油脂类均有良好的乳化作用、分散作用、增溶作用，在药剂制造中，本类辅料主要用作制造多种液体制剂(如芳香水剂、合剂、洗剂、乳剂等)、半固体制剂(如油膏剂、乳膏剂、栓剂等)、无菌、灭菌制剂(如滴眼剂、眼膏剂、注射剂等)。在选择使用本类辅料时，除了注意制剂的稳定性等因素外，还应特别注意其安全性。
Polysorbate 20 (common commercial brand names include Scattics, Alkest TW 20 and Tween 20) is a polysorbate-type nonionic surfactant formed by the ethoxylation of sorbitan before the addition of lauric acid. Its stability and relative nontoxicity allows it to be used as a detergent and emulsifier in a number of domestic, scientific, and pharmacological applications. As the name implies the ethoxylation process leaves the molecule with 20 repeat units of polyethylene glycol; in practice these are distributed across 4 different chains, leading to a commercial product containing a range of chemical species
Polysorbate 20 is used in cosmetics and skin care products as a surfactant, emulsifier, and fragrance ingredient. It is derived from Lauric Acid and is also a chemical mixture of sorbitol ethylene oxide, according to Wikipedia. It is sometimes derived from fruits and berries as well, leading to its fragrant properties. Polysorbate 20 can serve as a dispersing agent and mix oil and water, work as a fragrance solubilizer and stabilizer, act as a lubricator, and have a soothing effect on the skin (NatureBath.com).
聚山梨酯20在化妝品和皮膚護理產品中用作表面活性劑，乳化劑和香料成分。根據維基百科，它是從月桂酸衍生的，也是山梨醇環氧乙烷的化學混合物。它有時也來自水果和漿果，因此具有香氣。聚山梨酯20可用作分散劑，將油和水混合，用作香料增溶劑和穩定劑，充當潤滑劑，並在皮膚上具有舒緩作用(NatureBath.com)。

聚山梨酯20(常見的商業品牌名稱包括Scattics，Alkest TW 20和Tween 20)是在加入月桂酸之前，通過脫水山梨糖醇的乙氧基化作用而形成的聚山梨酯型非離子表面活性劑。
它的穩定性和相對無毒性使其可以在許多家庭，科學和藥理學應用中用作洗滌劑和乳化劑。
顧名思義，乙氧基化過程使分子帶有20個重複單元的聚乙二醇。 實際上，它們分佈在4條不同的鏈上，從而形成了包含一系列化學物質的商業產品。

＊ Used as a mild cleansing agent
＊ Derived from lauric acid, the primary fatty acid in coconuts
＊ Also used as a food additive
＊ Can be used to keep oral medications stable
In skin care, polysorbate 20 belongs to a group of cleansing agents most often derived from lauric acid, which is a medium-chain triglyceride (a type of fatty acid) found in coconuts.
Polysorbates for skin function as emulsifiers and have mild surfactant properties; some polysorbates are derived from the food ingredient sorbitol, which occurs naturally in many fruits, while others have a fatty acid component.
In addition to its use in both leave-on and rinse-off skin care products, polysorbate 20 is also used as a food additive to create a “spreading” feel (such as in cooling mint drops). Because of its stability, it is also used in drug delivery systems for oral medications to help keep them stable in the presence of digestive enzymes.
Though there have been some concerns raised about the safety of polysorbate 20, but the independent Cosmetic Ingredient Review panel has ruled it safe as used in cosmetics. The highest concentration of polysorbate 20 as used in cosmetics is in spray deodorants, where it is used in a concentration of 4%.
