Science
Mechanism of Action
As a highly effective chelating agent, Pentasodium Aminotrimethylene Phosphonate functions by binding to and inactivating problematic metal ions such as calcium and magnesium within a cosmetic matrix. This sequestration prevents the undesirable precipitation of metal salts, thereby ensuring product integrity, improving foaming and cleansing capabilities, and preserving formulation clarity over time.
