Sodium Lauroyl Glutamate
What is Sodium Lauroyl Glutamate?
Sodium Lauroyl Glutamate is a mild anionic surfactant synthesized from L-glutamic acid, a naturally occurring amino acid in proteins, and lauroyl groups from lauric acid sourced from coconut or palm oils. It belongs to the acyl glutamate family, prized in cosmetics for its skin-friendly profile. Primarily featured in rinse-off formulations such as shampoos, facial cleansers, body washes, and baby products, it works by lowering surface tension to lift away dirt, excess sebum, and residues while generating creamy foam. Its structure closely resembles skin's own ceramides and amino acids, minimizing barrier disruption compared to traditional sulfates. Additionally, it deposits a conditioning film on hair shafts, enhancing smoothness, reducing friction, and neutralizing static charges for better combability. Biodegradable and derived from renewable resources, it supports sustainable formulations without compromising performance.
