Polysorbate 80 is a synthetic compound derived from sorbitol, ethylene oxide, and oleic acid. It functions primarily as an emulsifier, helping to blend oil and water-based ingredients in cosmetic formulations. It also acts as a surfactant, reducing the surface tension of liquids, which can aid in cleansing and product spreadability.

Polysorbate 80 is primarily used as an emulsifier to help oil and water mix, creating stable product textures. It also acts as a solubilizer for fragrances and essential oils, allowing them to disperse evenly in water-based formulas.
Is Polysorbate 80 safe for sensitive skin?
While generally considered safe, Polysorbate 80 can occasionally cause mild irritation or sensitization in individuals with very sensitive skin, particularly at higher concentrations. Patch testing is recommended if you have known sensitivities.
