The product we are introducing here is sodium phosphate dibasic dihydrate with the CAS number 10028 - 24 - 7. Its chemical formula is Na₂HPO₄·2H₂O. It appears as colorless or white crystals that are odorless. The molar mass of sodium phosphate dibasic dihydrate is approximately 177.99 g/mol. It is freely soluble in water, and the resulting solution is slightly alkaline. This product is supplied directly from the factory, ensuring high - quality and cost - effective sourcing. It is produced under strict quality control standards to meet various industry requirements.
Sodium phosphate dibasic dihydrate has a wide range of applications in different fields. In the food industry, it is used as a food additive. It can function as a pH regulator, helping to maintain the optimal acidity or alkalinity of food products. For example, in dairy products, it can prevent the coagulation of milk proteins and improve the stability of the product. It is also used in the meat industry to improve water - holding capacity, thus enhancing the tenderness and juiciness of meat. In the pharmaceutical industry, it is used as an excipient in drug formulations. It can be used to adjust the pH of the drug solution, which is crucial for the stability and efficacy of the drugs. Additionally, it can be used in the production of dental products, such as toothpaste, to help maintain the proper texture and stability of the formulation. In the water treatment industry, it can be used as a water softener and a corrosion inhibitor. It can react with metal ions in water to form insoluble precipitates, reducing the hardness of water and preventing the corrosion of pipes and equipment.
When using sodium phosphate dibasic dihydrate, proper handling and safety precautions should be followed. First, always wear appropriate personal protective equipment, such as gloves and goggles, to avoid direct contact with the product. In the food industry, it should be added in accordance with the relevant food safety regulations and standards. Usually, it is dissolved in water first and then added to the food product during the production process. The dosage should be carefully controlled according to the specific requirements of the food product. In the pharmaceutical industry, it should be used in strictly controlled environments. When formulating drugs, it is necessary to accurately measure the amount of sodium phosphate dibasic dihydrate according to the formula. It is often added to the drug solution under stirring conditions to ensure uniform distribution. In the water treatment industry, it can be directly added to the water system. However, the dosage needs to be determined based on the water quality analysis results, such as the hardness and metal ion content of the water.
Case 1: Dairy Product Manufacturer
A dairy company was facing the problem of protein coagulation in its milk - based beverages. After adding sodium phosphate dibasic dihydrate as a pH regulator, they found that the stability of the product was significantly improved. By adding an appropriate amount (about 0.1 - 0.3%) of the product during the production process, the milk proteins remained stable throughout the shelf - life of the product, and the taste and texture of the beverage were also enhanced.
Case 2: Pharmaceutical Company
A pharmaceutical firm was developing a new oral liquid drug. The drug solution was unstable at the initial pH. By using sodium phosphate dibasic dihydrate to adjust the pH to the optimal range, the stability of the drug was greatly improved. The degradation rate of the active ingredients in the drug was reduced, which ensured the efficacy and quality of the drug.
Case 3: Water Treatment Plant
A water treatment plant was dealing with high - hardness water and pipe corrosion problems. After adding sodium phosphate dibasic dihydrate to the water treatment system, the hardness of the water was effectively reduced, and the corrosion of pipes was significantly inhibited. By continuously monitoring the water quality and adjusting the dosage of the product, the plant was able to maintain the water quality within the required standards and extend the service life of the pipes.
