EDTA-4Na is widely applied in industrial and household cleaning, water treatment, textile dyeing, cosmetics and personal care, as well as metal cleaning and electroplating, it sequesters calcium, magnesium and other metal ions to soften hard water, inhibit scale and corrosion, and elevate cleaning and system efficiency. It removes metal impurities for uniform dyeing and stable fabric quality, stabilizes personal care formulas by preventing discoloration and deterioration caused by trace metals, and also aids metal surface de-scaling and ensures smooth, consistent electroplating effects.
