Science
Mechanism of Action
This ingredient functions by significantly lowering the surface tension of liquid formulations, which allows immiscible substances to disperse more effectively. As an emulsifier, it stabilizes oil-in-water or water-in-oil mixtures, preventing separation. Additionally, it helps maintain skin health through its conditioning properties and contributes to effective cleansing by aiding in the removal of impurities.

Stability
While a precise optimal pH range for Disodium Hydrogenated Tallow Glutamate's stability is not directly specified, the parent compound, glutamic acid, demonstrates robust stability at extreme pH levels (0 and 14). However, at intermediate pH values, particularly around 2-3, and under elevated temperatures, it can convert into pyrrolidonecarboxylic acid. Disodium glutamate has a pKa of 6.8 and exhibits water solubility.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that amino acid alkyl amides, the class including Disodium Hydrogenated Tallow Glutamate, are safe for use in cosmetics, provided they are formulated to be non-irritating. This determination was made after a review of additional data for related ingredients, such as sodium lauroyl glutamate and lauroyl lysine, which were tested at various product concentrations and dilutions. No specific SCCS or FDA status for this exact ingredient has been identified.
