EDTA — ethylenediaminetetraacetic acid — is the most important industrial chelating agent. It binds metal ions, which is why it appears across water treatment, detergents, cosmetics, textiles, and food applications. The catch for buyers is that EDTA is sold in several forms, and they are not interchangeable.
Supreme Petro Chemicals supplies EDTA and its common salts from Chennai to manufacturers across South India.
What Is EDTA?
EDTA has CAS number 60-00-4 for the free acid. It works by sequestering metal ions such as calcium, magnesium, iron, and copper, preventing them from interfering with a process. The common commercial forms are EDTA acid, di-sodium EDTA, and tetra-sodium EDTA, each with different solubility and pH behaviour.
Grades and Forms
| Form | Solubility | Typical Use |
|---|---|---|
| EDTA acid | Low in water | Where a low-sodium chelant is needed |
| Di-sodium EDTA | Moderate | Cosmetics, cleaning, mildly acidic systems |
| Tetra-sodium EDTA | High | Detergents, alkaline cleaning, water treatment |
Industrial Applications
- Water treatment: Sequesters hardness ions and controls scale.
- Detergents: Improves cleaning by binding hardness ions that reduce surfactant performance.
- Cosmetics and personal care: Stabilises formulations by chelating trace metals.
- Textiles: Controls metal ions in dyeing and bleaching.
- Pulp and paper: Stabilises peroxide bleaching.
Packaging and Supply
EDTA grades are commonly supplied as powder in 25 kg bags. Specify the exact form (acid, di-sodium, tetra-sodium) and any documentation requirement, and share your monthly volume and delivery location.
