  • Applications

    Sodium lauroyl lactylate (CAS 13557-75-0) is a mild surfactant and emulsifier used across several industries. In cosmetics and personal care, it functions as a gentle cleansing surfactant and conditioning agent for skin and hair formulations. In household products, it serves as a surfactant and foam-promoting additive for cleaners and detergents. In industrial manufacturing, it acts as an emulsifier and processing aid in coatings, inks, and polymer formulations. In polymers/plastics, it can act as a processing aid to improve phase compatibility. In pharmaceuticals, it may be used as an emulsifier or excipient in topical formulations. In agrochemical formulations, it can serve as an emulsifier or surfactant adjuvant.
