Tetrasodium glutamate diacetate Usage And Synthesis

Description

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.

Uses

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.

Definition

TSGD (Tetrasodium Glutamate Diacetate) is a high purity, versatile and readily biodegradable chelating agent based upon L-glutamic acid, a natural and renewable raw material. Actives: 47-50%. Excellent chelating effectiveness controlling metal-catalyzed decomposition. Reduces water hardness and prevents precipitations. Boosts performance of preservatives improving shelf life. Stabilizes the pH value and is effective in a wide pH range. Does not sensitize human skin. Completely biodegradable as compared to phosphates and phosphonates. Effective alternative to EDTA.
