Science
Mechanism of Action
This ingredient functions as an anionic surfactant, effectively lifting dirt, excess oil, and other impurities from the skin's surface. Its unique molecular structure, which includes a carboxyl group, allows it to also exhibit characteristics of a non-ionic surfactant, offering versatile cleansing capabilities. Beyond cleansing, it serves as an emulsifier, promoting the stable mixture of oil and water components within a formulation, and actively contributes to the generation of a fine, creamy lather.

Safety
Safety Profile
This ingredient has not undergone explicit safety assessment by the CIR Expert Panel or SCCS. However, it is generally regarded as mild to the skin and eyes, with a low expectation of causing irritation even with prolonged or repeated use. Products incorporating Potassium Laureth-3 Carboxylate can qualify for EWG VERIFIED status, provided they adhere to specific restrictions and warnings concerning potential contamination from manufacturing impurities such as Ethylene Oxide and 1,4-Dioxane. While trace levels of potential allergens may be present, their typical concentrations are considered insufficient to trigger an allergic reaction, though individuals with extreme sensitivities should exercise caution.
