Product Name: High Quality EDTA Calcium Disodium, also known as Calcium disodium ethylenediaminetetraacetate. It has two CAS numbers: 23411 - 34 - 9 and 62 - 33 - 9. This product is offered at a low price without compromising on quality.
EDTA Calcium Disodium is a chelating agent. Chemically, it is a stable, water - soluble compound. Its molecular formula is C₁₀H₁₂CaN₂Na₂O₈, and the molecular weight is approximately 374.27 g/mol. It appears as a white crystalline powder, which is odorless and tasteless. The product is highly soluble in water, making it suitable for a variety of applications.
1. **Food Industry**: In the food industry, EDTA Calcium Disodium is used as a preservative and a chelating agent. It can prevent the oxidation and discoloration of food products by binding to metal ions, such as iron and copper, which can catalyze chemical reactions that lead to spoilage. For example, it is commonly used in canned fruits and vegetables to maintain their color and flavor during storage.
2. **Pharmaceutical Industry**: It is used in pharmaceutical formulations as a stabilizer. By chelating metal ions, it can prevent the degradation of drugs and ensure the stability and efficacy of pharmaceutical products. It is also used in some medical treatments for heavy metal poisoning, as it can bind to heavy metal ions in the body and facilitate their excretion.
3. **Cosmetic Industry**: In cosmetics, EDTA Calcium Disodium is used to improve the stability of products. It can prevent the formation of insoluble salts and maintain the clarity and stability of cosmetic formulations. It is often found in creams, lotions, and shampoos.
4. **Water Treatment**: It is used in water treatment processes to remove metal ions from water. By chelating metal ions, it can prevent the precipitation of metal salts, which can cause scaling in pipes and equipment. This helps to improve the efficiency of water treatment systems and prolong the lifespan of equipment.
1. **Food Industry**: When using EDTA Calcium Disodium in the food industry, it should be added in accordance with the relevant food safety regulations. Usually, it is added during the processing stage. The recommended dosage is generally in the range of 0.01% - 0.1% (w/w), depending on the type of food product. For example, in canned fruits and vegetables, it can be added to the brine solution at a concentration of 0.05%.
2. **Pharmaceutical Industry**: In pharmaceutical formulations, the amount of EDTA Calcium Disodium used depends on the specific requirements of the drug. It is usually added during the manufacturing process and thoroughly mixed to ensure uniform distribution. The dosage should be determined based on pre - clinical and clinical studies.
3. **Cosmetic Industry**: For cosmetic products, it is added to the formulation at a concentration of 0.05% - 0.2% (w/w). It should be dissolved in water before being added to the cosmetic emulsion to ensure good dispersion.
4. **Water Treatment**: In water treatment, the dosage of EDTA Calcium Disodium depends on the metal ion concentration in the water. It is usually added to the water treatment system in a continuous or batch - wise manner. The appropriate dosage can be determined through water quality analysis and pilot tests.
1. **Food Industry**: A fruit canning company was facing the problem of browning and spoilage of canned peaches. After adding 0.05% EDTA Calcium Disodium to the brine solution, the browning reaction was significantly reduced, and the shelf life of the canned peaches was extended from 6 months to 12 months. This not only improved the quality of the product but also reduced the economic losses caused by spoilage.
2. **Pharmaceutical Industry**: A pharmaceutical company was developing a new injectable drug. The drug was prone to degradation due to the presence of metal ions in the formulation. By adding an appropriate amount of EDTA Calcium Disodium, the stability of the drug was improved, and the degradation rate was reduced from 10% to 2% within 12 months of storage at room temperature. This ensured the efficacy and safety of the drug during its shelf life.
