About this ingredient
C20-40 Alketh-10 (INCI: C20-40 Alketh-10) is a nonionic emulsifier. It binds the oil and water phases and stabilizes the formula, which keeps creams and lotions from separating. This is a functional ingredient, not a skincare active. Its work is structural: keeping the emulsion stable. It gives no direct benefit to skin and 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 good. It is a mild surfactant, with low irritation and allergy potential, comfortable on sensitive skin. Most skin shows no reaction.
