CAS 9005-64-5: Polyoxyethylene sorbitan monolaurate

Description: Polyoxyethylene sorbitan monolaurate, commonly known as Tween 20, is a nonionic surfactant and emulsifier widely used in food, pharmaceuticals, and cosmetics. It is derived from the esterification of sorbitan and lauric acid, followed by ethoxylation. This compound is characterized by its ability to reduce surface tension, facilitating the mixing of oil and water phases, which makes it an effective emulsifying agent. Tween 20 is typically a pale yellow to amber liquid with a mild odor and is soluble in water, forming stable emulsions. Its hydrophilic-lipophilic balance (HLB) value is around 16.7, indicating a strong affinity for water, which enhances its emulsifying properties. Additionally, it is known for its low toxicity and is generally recognized as safe (GRAS) for use in food applications. Due to its versatile properties, Tween 20 is also employed in laboratory settings as a dispersing agent and in various formulations to improve stability and texture.
