A non-ionic emulsifier and solubilizer. It blends oil and water and dissolves fragrance and actives. Well tolerated.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
A mild functional emulsifier. Safe.
Polysorbate 21 (INCI: Polysorbate 21) is a nonionic emulsifier and solubilizer. It binds oil and water and dissolves fragrance and poorly soluble actives, which keeps the formula even and stable. This is a functional ingredient, not a skincare active. Its work is in the structure of the product, not in a direct skin benefit. It should not be judged as a skincare active. Because of its topical use and lack of systemic relevance, it can be used during pregnancy and breastfeeding without concern. Tolerance is high. It is a mild surfactant, with low irritation and allergy potential, comfortable on sensitive skin. Most skin does not react.
