What is Polysorbate 80 used for in cosmetics?

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.

Polysorbate 80

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.

Risk of short-term irritation — stinging, burning, dryness, redness, or discomfort. Common for strong actives, acids, retinoids, fragrances, and harsh surfactants.

Sensitization i0.5 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

Systemic exposure i0.1 / 4

Whether it has meaningful potential to be absorbed into the body at levels that may matter biologically. Most cosmetic ingredients score low unless there is known concern or high exposure.
