Tetrasodium EDTA
CAS Number: 64-02-8
Tetrasodium EDTA is a powerful chelating agent that sequesters calcium, magnesium, iron, and other metal ions in cleaning formulations, preventing hard water interference and metal-catalyzed degradation of active ingredients. It enhances the performance of surfactants in hard water and extends the shelf life of products containing bleach, peroxides, or enzymes.
