Science
Mechanism of Action
As a simple salt of the amino acid glutamic acid, Sodium Glutamate serves as a skin conditioning agent. Amino acids are fundamental components of the skin's natural moisturizing factor (NMF), playing a crucial role in maintaining skin hydration and supporting overall skin health. While its direct mechanism is conditioning, related amino acid-based ingredients also exhibit mild surfactant and emulsifying properties, which can aid in gentle cleansing and moisture retention.

Stability
Sodium Glutamate is freely soluble in water and sparingly soluble in ethanol (95%). A 5% aqueous solution typically presents a pH value ranging from 6.7 to 7.2. It is hygroscopic, meaning it readily attracts and retains moisture from the environment.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that amino acids and their simple salts, including Sodium Glutamate, are safe for use in cosmetic and personal care products. Dermal data indicate a low risk for irritation or sensitization. Furthermore, Monosodium Glutamate (MSG) is recognized as Generally Recognized As Safe (GRAS) by the FDA as a food additive.
