Ethylenediaminetetraacetic acid tetrasodium salt (EDTA-4Na) is a crucial organic chelating agent. It appears as a white powder, highly soluble in water, and forms stable water-soluble complexes with various metal ions. It is primarily used as a water softener, detergent additive, textile dyeing aid, photographic fixer, styrene-butadiene rubber activator, cosmetic additive, food additive, and anticoagulant in pharmaceuticals. It enhances cleaning efficacy, prevents metal interference, and treats water quality through chelation (binding metal ions).

This product is a widely used metal ion chelating agent. It can be employed in the textile industry for dyeing, water treatment, color photography, pharmaceuticals, daily chemical products, papermaking, and other sectors as an additive, activator, water purifier, metal ion sequestrant, and activator in the styrene-butadiene rubber industry. In dry acrylic fiber production, it counteracts metal interference to enhance the color and brightness of dyed fabrics. It is also used in liquid detergents to improve washing quality and boost cleaning efficacy.
Store in the original sealed container in a cool, dry, well-ventilated area, away from food and incompatible substances. Avoid exposure to sunlight and high temperatures to maintain product stability and prevent moisture absorption and caking. General storage requirements are at room temperature, with specific conditions determined by the product batch. However, the universal principles remain: keep sealed, protected from light, dry, and well-ventilated.
