Description and Uses

Tetrasodium Glutamate Diacetate is a 'chelating agent'. It usually appears as an odourless white powder that is soluble in water and is used as a multi-purpose, clear, liquid chelating agent and preservative booster. Tetrasodium Glutamate Diacetate inactivates metallic ions (charged particles) in product formulations, acting as a chelating agent. Free-roaming iron and copper ions in formulations can lead to rapid oxidation. Using a chelating agent helps to slow this process, allowing for the creation of products with improved stability and appearance. Tetrasodium Glutamate Diacetate is often found in sunscreen, facial cleanser, shampoo, makeup, lotion, cleansing wipes, bar soap, and other cleaning products.

N, N-Bis(Carboxymethyl)-L-glutamic acid tetrasodium salt is a cationic surfactant that has been used in the production of personal care products and industrial cleaners. The compound is soluble in water and can be used as a post-treatment to reduce the redox potential of hydrochloric acid.
