界面活性劑、親水性乳化劑、增溶劑,月桂酸衍生物,呈黏稠狀可以溶解於水脂肪酸,幫助乳化、濕潤、清潔等用途。化妝水類產品加入後會較為滑順,甚至有相當的起泡性[1]。

於化妝水中含量多在 1% 以下,一般健康的皮膚對此濃度通常不會感到刺激,但當皮膚受傷、發炎、起疹、角質偏薄時,部份可溶化劑就可能會造成刺痛、發癢現象[1]。

聚山梨醇酯類是一大類非離子表面活性劑,具有乳化、擴散、增溶、穩定等作用。在製藥、日化、食品、紡織等工業中,廣泛用作乳化劑、分散劑、增溶劑、穩定劑等。作為乳化劑高濃度電解質和pH值的改變對其乳化能力影響很小,是一大類優良的油/水型乳化劑。在製備油/水型乳化劑時,常與脫水山梨醇酯類合並使用,乳劑的穩定性更好。改變與其合用的乳化劑類型和用量,可以製得水/油型或油/水型的不同質地、不同稠度的乳劑、乳膏劑。由於對礦物油、植物油、動物油脂等各種油脂類均有良好的乳化作用、分散作用、增溶作用,在藥劑製造中,本類輔料主要用作製造多種液體製劑(如芳香水劑、合劑、洗劑、乳劑等)、半固體製劑(如油膏劑、乳膏劑、栓劑等)、無菌、滅菌製劑(如滴眼劑、眼膏劑、注射劑等)。在選擇使用本類輔料時,除了注意製劑的穩定性等因素外,還應特別注意其安全性。

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。
