Sodium Lauroyl Methyl Isethionate
What is Sodium Lauroyl Methyl Isethionate?
Sodium Lauroyl Methyl Isethionate is a synthetic anionic surfactant produced from lauric acid, typically sourced from coconut or palm kernel oils, combined with methyl isethionate derived from isethionic acid. It belongs to the isethionate family of cleansers commonly found in rinse-off personal care products such as facial cleansers, shampoos, body washes, and bubble baths. In formulations, it works by reducing the surface tension between water, oils, and dirt, enabling effective removal of impurities while maintaining a creamy lather. This ingredient stands out for its mild nature compared to harsher surfactants, helping to preserve the skin's natural moisture barrier during cleansing. Regulatory bodies like the Cosmetic Ingredient Review have assessed it as safe for use in cosmetics at typical concentrations.
