The generic name for Tween 20 is Polysorbate 20.
Understanding Polysorbate 20
Polysorbate 20 is a versatile and widely used chemical compound, specifically a polysorbate-type nonionic surfactant. It is chemically formed through the ethoxylation of sorbitan monolaurate, a process that gives it its unique properties as an emulsifier and solubilizer.
As a nonionic surfactant, Polysorbate 20 excels at reducing the surface tension between liquids, or between a liquid and a solid. This characteristic makes it invaluable in various formulations across numerous industries.
Common Commercial Brand Names
While Tween 20 is perhaps one of the most recognized trade names, Polysorbate 20 is marketed under several other commercial brand names globally. This highlights its widespread application and recognition in the chemical and pharmaceutical industries.
Here's a table listing some common commercial brand names for Polysorbate 20:
| Generic Name | Common Commercial Brand Names |
|---|---|
| Polysorbate 20 | Tween 20, Kolliphor PS 20, Scattics, Alkest TW 20, Kotilen-20 |
Applications of Polysorbate 20
Due to its properties as an effective emulsifier, wetting agent, and solubilizer, Polysorbate 20 finds extensive use in a variety of products. Its nonionic nature makes it compatible with a broad range of ingredients and less prone to irritation, making it suitable for sensitive applications.
Common applications include:
- Pharmaceuticals: Used to stabilize emulsions and suspensions in medications, enhancing drug delivery and absorption.
- Cosmetics and Personal Care Products: Found in lotions, creams, shampoos, and cleansers where it helps blend oil and water-based ingredients, creating stable and aesthetically pleasing textures. It also aids in solubilizing fragrances and essential oils.
- Food Industry: Utilized as an emulsifier in various food products, such as ice cream, baked goods, and dressings, to prevent separation of ingredients and improve texture.
- Laboratory and Research: Employed as a washing agent in immunoassay procedures (like ELISA) to remove non-specifically bound material, and as a solubilizing agent for membrane proteins.
