EDTA Disodium Dihydrate is a white, odorless crystalline powder. It has good solubility in water, and the solubility varies with temperature. At room temperature, it can dissolve to a certain extent, and the solubility increases as the temperature rises. The molecular formula of EDTA Disodium Dihydrate is C<sub>10<\/sub>H<sub>14<\/sub>N<sub>2<\/sub>Na<sub>2<\/sub>O<sub>8<\/sub>\u00b72H<sub>2<\/sub>O, and the molecular weight is approximately 372.24 g\/mol. It is a chelating agent with high purity and low price, which makes it very competitive in the market.<\/p>\n<h2 id=\"uses\">Utiliza\u00e7\u00f5es do produto<\/h2>\n<p>1. **In the Food Industry**: EDTA Disodium Dihydrate is used as a preservative and antioxidant. It can chelate metal ions such as iron, copper, and calcium, which helps to prevent the oxidation and spoilage of food. For example, in canned fruits and vegetables, it can maintain the color, flavor, and texture of the products by inhibiting the metal - catalyzed oxidation reactions.<br \/>\n   2. **In the Pharmaceutical Industry**: It is used as a stabilizer in some drugs. By chelating metal ions, it can prevent the degradation of drugs caused by metal - induced oxidation or hydrolysis. In addition, it can also be used in some diagnostic reagents as a chelating agent for metal ions.<br \/>\n   3. **In the Cosmetics Industry**: EDTA Disodium Dihydrate is added to cosmetics to improve the stability of the products. It can chelate metal ions in water and prevent them from reacting with other ingredients in cosmetics, such as preventing the formation of insoluble precipitates and maintaining the clarity and stability of the products.<br \/>\n   4. **In the Water Treatment Industry**: It is used to remove metal ions from water. By chelating metal ions in water, it can prevent the formation of scale and corrosion in pipes and equipment, and improve the quality of water.<\/p>\n<h2 id=\"usage\">Utiliza\u00e7\u00e3o do produto<\/h2>\n<p>1. **Preparation of Solutions**: First, calculate the amount of EDTA Disodium Dihydrate needed according to the required concentration. Then, add the appropriate amount of the product to a certain volume of water and stir continuously until it is completely dissolved. It is recommended to use distilled or deionized water to avoid the influence of metal ions in tap water.<br \/>\n   2. **Dosage Control**: The dosage of EDTA Disodium Dihydrate depends on the specific application. In the food industry, the dosage is usually regulated by relevant food safety standards. In the pharmaceutical and cosmetics industries, it is necessary to determine the appropriate dosage according to the formulation and requirements of the products. In the water treatment industry, the dosage needs to be adjusted according to the concentration of metal ions in the water.<br \/>\n   3. **Mixing and Reaction Conditions**: When using EDTA Disodium Dihydrate, it is necessary to ensure good mixing and appropriate reaction conditions. For example, in some reactions, it may be necessary to adjust the pH value of the solution to ensure the effectiveness of chelation.<\/p>\n<h2 id=\"cases\">Casos de utiliza\u00e7\u00e3o<\/h2>\n<p>1. **Food Preservation Case**: A food processing company produces canned tomatoes. They added a certain amount of EDTA Disodium Dihydrate to the canned tomatoes during the production process. After a period of storage, compared with the canned tomatoes without the additive, the color of the tomatoes with EDTA Disodium Dihydrate remained bright, and there was no obvious oxidation and spoilage. The texture of the tomatoes also remained intact, and the flavor was well - preserved.<br \/>\n   2. **Water Treatment Case**: A industrial plant was facing the problem of scale formation in its cooling water system. They added EDTA Disodium Dihydrate to the cooling water at a certain dosage. After a period of operation, the scale formation in the pipes and equipment was significantly reduced, and the heat transfer efficiency of the cooling water system was improved. At the same time, the corrosion rate of the equipment also decreased, which extended the service life of the equipment.<br \/>\n   3. **Cosmetics Stability Case**: A cosmetics company developed a new lotion. They added EDTA Disodium Dihydrate to the lotion formula. During the storage and shelf - life test, the lotion remained clear and stable, without the formation of precipitates or changes in texture.
