EDTA tetrasodium salt (CAS 64‑02‑8) with ≥ 99 % purity is a premier chelating agent used for water softening and formulation stability. The white powder exhibits a pH of 10.5‑11.5 in aqueous solution and dissolves readily, reaching approximately 100 g/L at 20 °C. It complexes Ca²⁺, Mg²⁺ and Fe³⁺ ions, preventing scale formation and enhancing the performance of surfactants. In household chemicals EDTA 4Na is added to shampoos, detergents and cleaning agents to mitigate the adverse effects of hard water on foam generation. For water treatment applications it acts as a scale inhibitor in boiler and cooling‑water systems, allowing consistent hardness control without additional acid dosing. Beyond these uses, EDTA 4Na is frequently incorporated into dishwashing liquids where it binds transition‑metal ions that could otherwise deactivate enzymatic builders, preserving enzyme activity. In personal‑care formulations it is compatible with amino‑based surfactants, polymers, and cationic conditioners, helping to maintain pH stability and preventing discoloration. In industrial cleaning concentrates, the salt is often paired with sodium carbonate or citric acid to boost overall water‑softening efficiency, and may be combined with anti‑scaling polymers for a synergistic protection against deposit buildup. This grade is valued for its high reactivity, thermal stability up to 200 °C, and complete documentation package (TDS, SDS, COA), simplifying product certification. Storage guidelines recommend keeping the material in a dry, cool environment, sealed in moisture‑proof containers and protected from direct sunlight. Shelf life under proper conditions is at least 24 months. When handling the powder, the use of protective gloves and goggles is advised, and during dissolution the solid should be added gradually to a moving water stream to avoid localized pH spikes.

Store EDTA tetrasodium salt in a dry, well‑ventilated area at ambient temperatures (approximately 15 °C–30 °C) away from direct sunlight and heat sources. When the original sealed packaging is intact, the typical shelf life is at least 12 months, but periodic checks for moisture ingress or discoloration are advisable. During handling wear protective gloves and safety goggles, and avoid inhalation of dust. Ensure the high‑density polyethylene container remains undamaged to maintain moisture‑proof integrity.
