What Is Tetrasodium Glutamate Diacetate?

Tetrasodium glutamate diacetate is a vegetable-based chelating agent.

Tetrasodium Glutamate Diacetate Uses

Tetrasodium glutamate diacetate is often found in sunscreen, facial cleanser, shampoo, makeup, lotion, and other products.[1] You can also find it in detergents, cleansing wipes, bar soap, and other cleaning products.[2]

How Tetrasodium Glutamate Diacetate Is Made

Metal organic acid chelates are made by reacting a metal ion from a soluble metal salt with an organic acid or its salt. For example, amino acid chelates have generally been made by reacting one or more amino acids, dipeptides, polypeptides, or protein hydrolysate ligands in an aqueous environment. Under appropriate conditions, this causes an interaction between the metal and amino acids to form amino acid chelates.

Organic acid chelates have been generally been made by producing a reaction by using either amino acids, picolinic, nicotinic acids, or hydroxycarboxylic acids.[4]

Is Tetrasodium Glutamate Diacetate Safe for Skin?

Research shows the ingredient is not a strong skin irritant.[5]

Why Puracy Uses Tetrasodium Glutamate Diacetate

We use tetrasodium glutamate diacetate as a rinsing aid in several of our products because it temporarily reduces the surface tension of water. This creates a sheeting effect and helps suds and grime rinse away quickly and completely. Fewer water droplets left on surfaces reduces the need to rinse repeatedly to get soap off (and therefore reduces water consumption).
