 EDTA 4Na (Tetrasodium Ethylenediaminetetraacetate)

Product Introduction EDTA 4Na, chemically known as tetrasodium ethylenediaminetetraacetate, is a high-performance chelating agent and metal sequestering agent widely recognized for its exceptional ability to bind with metal ions. As a critical chemical intermediate, it plays a vital role across diverse industries, from water treatment and textiles to food processing and pharmaceuticals. Chemical Properties EDTA 4Na appears as a white crystalline powder with a molecular formula of C₁₀H₁₂N₂O₈Na₄ and a molecular weight of 380.17 g/mol. It is highly soluble in water, forming a slightly alkaline solution (1% aqueous solution pH ≈ 11.8), while showing minimal solubility in organic solvents like ethanol, ether, and chloroform. Its CAS number is 6381-92-6, and it is classified as low-toxicity, with an oral LD50 of 2000 mg/kg in rats, ensuring safe handling under standard conditions. Core Characteristics The standout feature of EDTA 4Na is its broad chelating capacity—it can form stable 1:1 complexes with nearly all metal ions, including calcium, magnesium, iron, copper, and heavy metals like lead and mercury.

This property makes it an ideal choice for: Hard water softening: Effectively sequestering calcium and magnesium ions to prevent scale formation in industrial and domestic systems. Metal ion masking: Interfering with unwanted metal reactions in chemical processes, such as dyeing and plating. Stabilization: Acting as an antioxidant and stabilizer in cosmetics, detergents, and food products to extend shelf life. Compared to EDTA disodium salt, EDTA 4Na offers higher solubility in water and better performance in alkaline environments (pH ≥ 8), where its chelating efficiency peaks. It also demonstrates exceptional thermal stability, remaining intact even in hot water, which is critical for high-temperature industrial applications.

Key Applications

Water Treatment: Used as a primary softening agent to remove hardness-causing ions, protecting pipes, boilers, and cooling systems from corrosion and scaling.

Textile & Dyeing: Enhances color brightness and uniformity in synthetic fiber dyeing (e.g., acrylic) by neutralizing metal impurities that cause discoloration.

Food & Beverage: Employed as a preservative and metal chelator in dairy, baked goods, and beverages to prevent oxidation and nutrient degradation. Pharmaceuticals: Serves as a raw material for drug formulations, ensuring stability in solutions containing metal-sensitive compounds. Cosmetics & Personal Care: Included in shampoos, creams, and lotions to bind metal ions that accelerate product spoilage or cause skin irritation. Industrial Manufacturing: Utilized in rubber production (as an activator), paper pulping, photography (for fixing solutions), and chemical plating processes.

Safety & Packaging EDTA 4Na is non-corrosive and non-flammable, with no significant environmental hazards under normal use. It is typically packaged in 80 kg bags lined with double-layer plastic bags or 25 kg cartons, designed to maintain moisture resistance during storage. For optimal performance, it should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and incompatible chemicals. Conclusion With its versatile chelating capabilities, high purity (≥99% content), and adaptability across pH ranges, EDTA 4Na remains an indispensable chemical in modern industry. Whether for improving product quality, enhancing process efficiency, or ensuring safety, it delivers reliable performance that meets the demands of global markets.
