Disodium EDTA (EDTA-2NA) — 99% Purity
Product Summary
Disodium EDTA (EDTA-2NA) is a white crystalline powder and a widely used chelating agent. It sequesters metal ions, improves stability of formulations, prevents color changes and extends shelf life of products. Supplied in bulk with consistent quality, suitable for cosmetics, food processing (where permitted) and industrial applications.
Product Highlights
- Purity: 99% minimum
- High solubility in water
- Effective chelation across a broad pH range
- Stable crystalline form for easy handling and dosing
What is Disodium EDTA?
Disodium EDTA (ethylenediaminetetraacetic acid, disodium salt) is an aminopolycarboxylic acid used to bind metal ions such as Ca2+, Mg2+, Fe2+/3+ and heavy metals. The chelation reduces metal-catalyzed oxidation and stabilizes formulations in cosmetics, detergents, food processing and industrial applications.
Benefits
- Prevents metal-catalyzed degradation and discoloration
- Improves clarity and transparency in aqueous systems
- Enhances preservative efficacy in personal care products
- Reduces scale and hardness effects in industrial processes
Applications
- Cosmetics & personal care (shampoos, lotions)
- Food processing (as sequestrant where permitted)
- Detergents and cleaners
- Water treatment and industrial processing
- Oilfield chemicals and leather processing
