Category Archives: Disodium EDTA

The primary function of disodium EDTA is to bind with metal ions from the hard water to prevent the metals from being deposited onto the hair, scalp and skin. The acid converts hard tap water to soft water which is gentler on the skin. A product that contains antioxidants like Vitamin E is reactive and binds to these free metal ions, reducing the efficacy of the product. Chelators like disodium EDTA protect the antioxidants present in formulations by binding with the free metals ions.
