TETRASODIUM GLUTAMATE DIACETATE

Safety grade: A

This is a chelating agent, which means it acts like a magnet that grabs onto trace metals found in water and cosmetic formulas. By binding to these metals, it keeps them from causing the product to break down or become discolored.

This ingredient is used in cosmetics to bind unwanted metal ions in the formula, which prevents product degradation, extends shelf life, and maintains product stability and appearance.

Graded using: COSING, FDA.
