DIAMMONIUM EDTA
Safety grade: A**
This is a mineral salt derived from an amino acid that acts like a protective shield for cosmetic products. It works by binding to trace metals that could otherwise cause products to degrade or turn rancid.
Diammonium EDTA prevents cosmetic products from spoiling and oxidizing by trapping metal impurities, while also helping preserve the product's effectiveness and appearance over time.
