Polysorbate 80 is an ingredient commonly used in cosmetics as an emulsifier and surfactant. It acts as a bridge between water and oil-based ingredients, allowing them to mix and form stable emulsions. Polysorbate 80 is derived from natural sources and is commonly produced by the esterification of sorbitol with fatty acids derived from vegetable oils. Its chemical formula is C64H124O26. Polysorbate 80 appears as a yellowish, viscous liquid. It is utilized in a wide range of cosmetic products, including creams, lotions, serums, and even some makeup formulations, to create smooth textures and ensure proper dispersion of ingredients.

What is POLYSORBATE 80 used for?

Polysorbate 80 is widely used in various industries, including cosmetics, due to its versatile properties and benefits. It serves as an effective emulsifier and solubilizer, allowing for the blending of water and oil-based ingredients in cosmetic formulations. This makes it valuable in creating stable emulsions, such as creams, lotions, and serums, ensuring proper dispersion of active ingredients. Polysorbate 80 is also utilized in haircare products to enhance the spreadability and distribution of conditioning agents. In addition, it finds applications in cosmetic products like foundations, eyeshadows, and lipsticks, where it aids in the uniform dispersion of pigments, resulting in smooth and consistent application.


Polysorbate 80 is produced through the ethoxylation process, where sorbitol, a sugar alcohol derived from natural sources, is reacted with ethylene oxide. This reaction creates a polyethylene glycol chain attached to the sorbitol molecule, resulting in the formation of Polysorbate 80.

What does POLYSORBATE 80 do in a formulation?

  • Emulsifying
  • Surfactant

Safety profile

Polysorbate 80 is generally considered safe for use in cosmetics. It is not considered toxic when used in recommended concentrations. However, some individuals with sensitive skin may experience mild skin irritation, therefore, a patch test is necessary. Further, it is generally considered vegan as it is derived from natural sources and does not contain animal-derived ingredients.
