What is Sodium stearoyl glutamate?
Sodium stearoyl glutamate (CAS 38517-23-6) is an amino acid-based surfactant derived from stearic acid and glutamic acid.
Where is Sodium stearoyl glutamate used?
- Food manufacturing: emulsifier in processed foods, improving fat dispersion and texture consistency in baked goods and margarine
- Personal care: stabilizes oil-in-water emulsions in creams, lotions, and sunscreens
- Cleansing formulations such as facial washes and micellar products: gentle wetting and degreasing action without disrupting the skin barrier
- Powder-based cosmetics: modifies surface tension to enhance pigment dispersion and adhesion
- It functions as an emulsifier and skin-conditioning agent.
Good to know: Food-grade material conforms to relevant purity standards for use as a direct food additive. Food-grade and cosmetic-grade specifications are both commercially available.
Commercial specifications
- Standardized for active content and pH compatibility
