- ≥ 99% High Purity and Consistency
- Effective Chelating Power
- Customizable Particle Size
- Highly Water-soluble
- 2 Years Shelf Life
Types of Our Sodium EDTA
Disodium EDTA (EDTA-2Na)
This form contains two sodium ions per EDTA molecule. It is commonly used in applications where a lower binding capacity is required, such as in cleaning agents, cosmetics, and food preservation.
Item | Standard |
Purity (by Titration) | ≥ 99% |
pH (1% aqueous solution) | 4.0 – 6.0 |
Water Content | ≤ 1.0% |
Chloride (Cl) | ≤ 0.05% |
Iron (Fe) | ≤ 0.001% |
Heavy Metals (as Pb) | ≤ 0.001% |
Arsenic (As) | ≤ 0.0002% |
Sulfate (SO₄) | ≤ 0.05% |
Melting Point | 250°C (decomposes) |
Tetrasodium EDTA (EDTA-4Na)
Containing four sodium ions, tetrasodium EDTA is more potent and is used in more demanding applications like water treatment, pharmaceuticals, and industrial cleaning where strong metal chelation is necessary.
Item | Standard |
Purity (by Titration) | ≥ 99% |
pH (1% aqueous solution) | 10.0 – 11.0 |
Water Content | ≤ 1.0% |
Sodium (Na) | 10.5% – 11.5% |
Chloride (Cl) | ≤ 0.05% |
Iron (Fe) | ≤ 0.001% |
Heavy Metals (as Pb) | ≤ 0.001% |
Arsenic (As) | ≤ 0.0002% |
Sulfate (SO₄) | ≤ 0.05% |
Melting Point | 300°C (decomposes) |
Applications of Tetrasodium EDTA
Water Treatment
- Sodium EDTA is commonly used in water softeners, where it effectively binds to calcium and magnesium ions, preventing scale formation.
Food Industry
- In food preservation, Sodium EDTA binds metal ions, preventing oxidation and discoloration, enhancing shelf life and product quality.
Cosmetics and Personal Care
- Sodium EDTA stabilizes formulations by neutralizing metal ions, improving the effectiveness and longevity of shampoos, lotions, and creams.
Pharmaceuticals
- Used in drugs to stabilize formulations and in chelation therapy, removing toxic metals and supporting effective medical treatments.
Agriculture
- In fertilizers, Sodium EDTA binds micronutrients, enhancing their availability to plants and improving nutrient uptake for better crop yield.
Metal Processing
- Sodium EDTA is used in cleaning agents to remove metal ions, rust, and scale, improving cleaning efficiency and performance.
