Used as a stabilizer and antioxidant in cosmetics and personal care products, particularly in formulations sensitive to metal ions. Helps prevent discoloration and degradation of active ingredients by chelating trace metal contaminants. Commonly found in creams, lotions, and sunscreens to enhance product shelf life. Also utilized in some pharmaceutical preparations to maintain the stability of zinc-containing compounds. Its chelating action supports consistent performance in multi-component systems where metal interference could reduce efficacy.
