Product Q&A

Q:What is EDTA-4NA used for?

EDTA-4NA is a chelating agent used to bind metal ions in water, detergents, textiles, papermaking, and industrial processes. It prevents scale formation and improves cleaning performance.

Q:What is the recommended dosage?

Dosage depends on application and water hardness. In detergents, typical use is 0.5%-2.0% of formulation. In water treatment, dosage is based on metal ion concentration. Testing is recommended.

Q:Is EDTA-4NA safe for use?

Yes, it is safe when used as directed. It is non-toxic and approved for use in food, pharmaceuticas, and cosmetics under regulatory limits. Avoid excessive exposure to skin and eyes.

Q:How does it differ from EDTA-2NA?

EDTA-4NA is tetrasodium salt with higher solubility and alkalinity. EDTA-2NA is disodium salt with lower pH and solubility. Choose based on pH requirements of your system.

Q:What is the shelf life?

24 months when stored in a cool, dry place with packaging sealed. Keep away from moisture and direct sunlight.
