Sodium Lauroyl Lactylate, derived from the condensation of lauric acid and lactylate using lactic acid and natural fatty acids from coconut oil, serves as an effective emulsifying agent and a secondary surfactant in personal care products. Its properties include a noteworthy ability to generate and maintain foam, alongside a moisturizing effect attributed to its re-fatting capabilities. This ingredient is particularly beneficial in cleansing formulations, providing a desirable moisturizing after-feel while aiding in solubilization and emulsification. Its mild nature and high foaming capacity make it an excellent alternative to alkanolamides, and it can be integrated into formulations without the need for heating, thus conserving energy. Being food-grade and renewable, Sodium Lauroyl Lactylate is also compatible with a broad range of raw materials found in shampoos, including both anionic and nonionic surfactants. It is especially recommended for mild formulations suitable for sensitive facial and intimate areas, as well as for children's products.
