Etidronic Acid

Etidronic Acid, also known as 1-Hydroxyethelydene-1,1-Diphosphonic Acid (HEDP), is primarily used in cosmetics as a chelating agent. It helps to improve the stability and performance of cosmetic formulations by binding with metal ions, which can otherwise degrade the product. Although it's not directly beneficial for skin health, it helps maintain the efficacy of other skincare ingredients.
