Science

Mechanism of Action

Functioning primarily as a surfactant, Sodium Ceteth-13 Carboxylate significantly lowers the surface tension between disparate components within a formula, facilitating the miscibility of oil and water. On the skin, it actively attracts and encapsulates dirt, sebum, and other impurities, allowing them to be effortlessly rinsed away with water.
