Tween 40
Description :
Overview of Tween 40
Tween 40 is a non-ionic surfactant widely used in pharmaceutical, cosmetic, and industrial formulations. Known for its emulsifying, stabilising, and solubilising properties, Tween 40 helps combine oil and water phases in creams, lotions, and other emulsions.
Its chemical name is Polyoxyethylene (20) Sorbitan Monopalmitate. Tween 40 is typically supplied as a clear, viscous liquid, compatible with a wide range of ingredients, making it ideal for stable emulsions and smooth formulations.
Application of Tween 40
Pharmaceutical Emulsions
Tween 40 in pharmaceutical emulsions is extensively used to stabilise oil-in-water emulsions, enhancing the effectiveness and consistency of topical creams, medications, and liquid formulas. It guarantees even distribution of the active ingredient.
Cosmetic and Skincare Products
Tween-40 is a component of creams, serums, lotions and hair products as an emulsifier as well as a solubiliser. It assists in creating a smoother texture, increased absorption and better product stability. It is typically combined with Tween 20, Span 80, Cetyl Alcohol, and Glycerin to enhance the formulation's performance.
Industrial and Speciality Applications
Tween 40 can also be found in detergents, food and chemical processing industries, in which its stabilising and emulsifying properties are essential to ensure that ingredients are mixed evenly.

Frequently Asked Questions (FAQs)
-
What is Tween 40 used for?
Tween 40 is used as a non-ionic surfactant and emulsifier in pharmaceutical emulsions, cosmetics, and industrial formulations. -
Is Tween 40 vegan-friendly?
Yes, Tween 40 can be made from plants and is vegan-friendly, making it suitable for formulations that are ethical. -
What is another name for Tween 40?
It is commonly known as Polysorbate 40 or Polyoxyethylene (20) Sorbitan Monopalmitate. -
What is the difference between Tween 20 and Tween 40?
The Tween 20 is a smaller chain of fatty acids (laurate) in comparison to the Tween 40 (palmitate), which makes the Tween 40 somewhat more hydrophobic, and suited to denser Emulsions. -
Can Tween 40 be used in skincare products?
Yes, Tween 40 is commonly used in creams, lotions, serums, and hair care products to improve texture, solubility, and stability.
