What Is Tetrasodium glutamate diacetate?

Tetrasodium glutamate diacetate is a vegetable-based chelating agent.

What Does Tetrasodium glutamate diacetate Do in Our products?

Tetrasodium glutamate diacetate acts as a rinsing aid in our products. It is found in sunscreen, facial cleanser, shampoo, makeup, lotion, and other products.[1] It is also found in detergents, cleansing wipes, bar soap, and other cleaning products.[2]

Why Puracy Uses Tetrasodium glutamate diacetate

We use tetrasodium glutamate diacetate as a rinsing aid in several of our products, such as our Natural Dish Soap, because it temporarily reduces the surface tension of water, creating a sheeting effect and helping make suds and grime rinse away quickly and completely. This reduces reduces the number of water droplets left to dry on surfaces, reduces the need to rinse repeatedly to get soap off, and reduces water consumption. Research shows the ingredient is not a strong skin irritant.[5]

How Tetrasodium glutamate diacetate Is Made

The term chelate is from the Greek word for “claw.”[3] 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, and polypeptides or protein hydrolisate ligands in an aqueous environment under appropriate conditions that cause the interaction between the metal and amino acids to form an amino acid chelates. Organic acid chelates have been generally made by reaction using either amino acids, picolinic, nicotinic acids, or hydroxycarboxcylic acids.[4]
