Science
Mechanism of Action
This ingredient functions primarily by reducing surface tension between immiscible liquids, acting as an emulsifier to achieve stable dispersion of oil and water phases. As a surfactant, it contributes to cleansing, boosts foam production, and enhances overall foaming properties. Furthermore, it serves as a hydrotrope, increasing the solubility of poorly water-soluble substances, and acts as a skin conditioning agent to help maintain skin in good condition.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded Disodium Cetearyl Sulfosuccinate is safe for use in cosmetics at current concentrations and practices, provided formulations are non-irritating. While generally considered safe, sulfosuccinates, as a class, carry a potential for ocular or skin irritation if not properly formulated, particularly in products designed for prolonged skin contact. However, the risk of sensitization is deemed low. No specific maximum concentration for Disodium Cetearyl Sulfosuccinate was established by CIR, though a related compound, Disodium Lauryl Sulfosuccinate, is used up to 3% in leave-on and up to 7% in rinse-off products.
