Ethylene Diamine Tetraacetic Acid (EDTA) is a workhorse in industrial chemistry, and its various salt forms offer tailored properties for specific applications. Among the most common are Tetrasodium EDTA (EDTA-4Na) and Disodium EDTA (EDTA-2Na). Understanding their differences in terms of solubility, pH, and application suitability is crucial for formulators and procurement specialists. As a premier manufacturer and supplier of industrial chemicals in China, we provide both high-quality EDTA-4Na and EDTA-2Na to meet diverse industry needs.

EDTA-4Na (Tetrasodium EDTA, CAS 13254-36-4) is highly soluble in water and has an alkaline pH, typically around 11.0-12.0 for a 40% solution. This makes it an excellent choice for applications requiring a high pH environment or where maximum water solubility is needed. It is widely used in detergents, industrial cleaning agents, and certain water treatment processes where alkalinity is beneficial or tolerated. For those looking to buy EDTA-4Na, its effectiveness in sequestering metal ions in alkaline conditions makes it a go-to chelating agent.

EDTA-2Na (Disodium EDTA, CAS 1200-71-1, though CAS 13254-36-4 is also sometimes associated with it depending on hydration) is also soluble in water but operates in a more neutral to slightly acidic pH range, typically around 4.0-5.0 for a 5% solution. This makes it suitable for applications where maintaining a neutral pH is important, such as in some cosmetic formulations, certain types of metal plating baths, and specific textile dyeing processes where pH control is critical. Its milder pH profile offers advantages in applications sensitive to high alkalinity.

For industries seeking to purchase these essential chelating agents, partnering with a reliable manufacturer and supplier in China ensures both quality and cost-effectiveness. Our product specifications detail the purity levels and chelate values for both EDTA-4Na and EDTA-2Na, guaranteeing performance for your specific requirements. Whether your application demands the strong chelating power of EDTA-4Na in alkaline conditions or the pH-controlled effectiveness of EDTA-2Na, we are equipped to supply your needs.
