What is tween 20?

Tween 20, also known as Polysorbate 20, is a non-ionic surfactant that is commonly used in pharmaceuticals, cosmetics, and food products. It is synthesized by the ethoxylation of sorbitan and oleic acid.

Tween 20 is a water-soluble emulsifier, meaning it helps to mix oil and water together in products such as lotions, creams, and emulsions. It has a wide range of applications, including as a solubilizer, stabilizer, and dispersant in various formulations.

In pharmaceuticals, Tween 20 is often used in oral and topical medications, as well as in vaccines and protein-based therapeutics. In cosmetics, it is commonly found in skincare products, shampoos, and makeup, where it helps to improve the texture, stability, and homogeneity of the product.

Overall, Tween 20 is a versatile and widely used ingredient in various industries, thanks to its emulsifying and solubilizing properties. It is generally considered safe for use in products when used as directed.
