What is Disodium EDTA Used for
- Industrial Cleaning & Water Treatment: Softens hard water by trapping calcium and magnesium ions, improving cleaning efficiency in detergents and preventing scale in boilers and cooling systems.
- Cosmetics & Personal Care: Stabilizes shampoos, soaps, creams, and lotions by binding metal ions that cause discoloration, rancidity, and formula separation .
- Food & Beverage Preservation: Used as a food additive (E385) to maintain color, flavor, and texture in canned goods, salad dressings, soft drinks, and mayonnaise by preventing metal-catalyzed oxidation.
- Pharmaceuticals & Medicine: Acts as a stabilizer in liquid medications, eye drops, and injectable solutions, and is used in chelation therapy for heavy metal detoxification .
Laboratory & Analytical Chemistry: Used to prepare buffer solutions, mask interfering metal ions in chemical analysis, and as a chelating agent in biochemical research and titration methods .
FAQ of Disodium EDTA
Our Disodium EDTA meets ≥99% purity with strict heavy metal limits. It complies with USP, EP, and food-grade (E385) standards. Certificate of Analysis (CoA) provided with every batch.
It binds trace metals (iron, copper) that can cause discoloration, rancidity, and formula breakdown. This keeps creams, shampoos, and lotions stable and fresh longer.
Check appearance (white powder), pH of 1% solution (4.0-5.0), and assay by titration. Our CoA provides reference values — match against your test results.
