Sodium Laurate
What is Sodium Laurate?
Sodium laurate is the sodium salt of lauric acid, a medium-chain saturated fatty acid primarily obtained from coconut oil or palm kernel oil. Classified as an anionic surfactant, it appears in rinse-off cosmetics such as bar soaps, liquid hand soaps, body washes, facial cleansers, and shampoos. Its primary function involves decreasing water's surface tension to produce foam and create micelles—tiny structures that trap oils, dirt, and sebum for easy rinsing. This action ensures effective removal of surface impurities while being gentle on skin barriers. As an emulsifier, it forms a protective layer at oil-water interfaces, promoting uniform blending in creamy or lotion-like formulations. Derived from renewable sources, it supports clean-rinse properties, minimizing residue and contributing to product efficacy in daily hygiene routines.
