High Quality EDTA 4NA is a well - known chemical compound with multiple CAS numbers: 64 - 02 - 8, 67401 - 50 - 7, 13254 - 36 - 4, and 13235 - 36 - 4. EDTA 4NA stands for Ethylenediaminetetraacetic acid tetrasodium salt. It is a white, odorless powder that is highly soluble in water.
The chemical formula of EDTA 4NA is C₁₀H₁₂N₂Na₄O₈. The molar mass is approximately 380.17 g/mol. It has excellent chelating properties, which means it can bind to metal ions and form stable complexes. This product is offered at a low price while maintaining high quality, making it a cost - effective choice for various industries.
1. **Water Treatment**: In water treatment plants, EDTA 4NA is used to remove heavy metal ions such as lead, mercury, and cadmium from water. By forming stable complexes with these metal ions, it prevents them from causing harmful effects on human health and the environment.
2. **Cosmetics Industry**: It is added to cosmetics to chelate metal ions that can cause oxidation and deterioration of the products. This helps to extend the shelf - life of cosmetics and maintain their stability and quality.
3. **Food Industry**: EDTA 4NA is used as a food additive (E386) to prevent the discoloration and spoilage of food products. It can chelate metal ions in food, which inhibits the growth of microorganisms and the oxidation of fats and oils.
4. **Textile Industry**: In textile processing, it is used to remove metal ions from fabrics, which can improve the dyeing process and the quality of the dyed fabrics.
When using High Quality EDTA 4NA, it is essential to follow the recommended dosage and safety procedures. The product should be stored in a cool, dry place away from direct sunlight and heat sources.
For water treatment, the appropriate dosage depends on the concentration of metal ions in the water. Generally, a small amount of EDTA 4NA is dissolved in water and then added to the water to be treated. The solution should be well - mixed to ensure efficient chelation.
In the cosmetics and food industries, the usage is strictly regulated. The dosage should comply with relevant food and cosmetic safety standards. It is usually added during the manufacturing process at a specific stage to achieve the best results.
**Case 1: Water Treatment in a Small - Scale Industrial Plant**
A small - scale metal - plating factory was facing the problem of high levels of heavy metal ions in its wastewater. After adding High Quality EDTA 4NA to the wastewater treatment system, the concentration of heavy metal ions decreased significantly. The dosage of EDTA 4NA was adjusted according to the initial metal ion concentration. After treatment, the wastewater met the local environmental discharge standards, and the factory avoided potential environmental fines.
**Case 2: Cosmetic Product Preservation**
A cosmetic company was developing a new moisturizing lotion. During the stability testing, they found that the lotion was prone to oxidation and discoloration due to the presence of metal ions in the raw materials. By adding a small amount of EDTA 4NA to the formula, the oxidation process was effectively inhibited. The lotion maintained its original color and texture during the entire shelf - life testing period, which improved the product's marketability.
