Cleaning Chemicals
EDTA (ethylenediaminetetraacetic acid) and its sodium salts, EDTAdisodium(EDTA-2Na)and EDTA tetrasodium(EDTA-4Na), playsignificant roles in household cleaning products. Both have strongmetal ion chelating abilities. EDTA-2Na, which is more soluble andweakly acidic, is commonly used in cosmetics to preventdiscoloration and oxidation caused by metal ions. EDTA-4Na, withhigher alkalinity, is used in textile dyeing, water treatment, anddetergents,enhancing cleaning quality and effectiveness.
