Disodium 2-Sulfolaurate
What is Disodium 2-Sulfolaurate?
Disodium 2-sulfolaurate is the disodium salt of 2-sulfolauric acid, a derivative of lauric acid sourced mainly from coconut or palm kernel oils. As an anionic surfactant, it functions in cosmetics by reducing water's surface tension, enabling the formation of micelles that encapsulate oils, dirt, and residues for easy rinsing. This makes it a key component in rinse-off products like facial cleansers, shampoos, body washes, and micellar waters. Its mild nature stems from its specific chemical structure, which provides effective cleaning and stable foam without harshly disrupting the skin's lipid barrier. Often selected for natural or sensitive-skin formulas, it supports product stability as an emulsifier while prioritizing gentleness over aggressive detergents.
