Science

Mechanism of Action

This ingredient functions synergistically as a surfactant, emulsifier, and solubilizer. Its unique carboxyl group imparts a dual non-ionic and anionic character, allowing it to efficiently lower surface tension, effectively lifting and washing away dirt and oils while providing mild yet robust foaming. It also aids in combining disparate oil and water phases to ensure product stability and facilitates the even distribution of lipophilic components within aqueous formulations.

Sensitization risk Low

POTASSIUM LAURETH-10 CARBOXYLATE itself has not been subject to a direct safety assessment by the Cosmetic Ingredient Review (CIR) Expert Panel. However, the CIR has deemed related alkyl PEG ethers, including Laureth-10, safe when formulated to be non-irritating. Potential residual contamination with Ethylene Oxide and 1,4-Dioxane is a noted consideration for ethoxylated ingredients.
