Sodium Trimetaphosphate, with the CAS number 7785 - 84 - 4, is a white crystalline powder. It has a molecular formula of (NaPO₃)₃ and a molecular weight of approximately 305.94 g/mol. This product is typically supplied in various purities, with high - quality factory - supplied options often having a purity of over 95%. It is highly soluble in water, forming a clear, colorless solution, and it is stable under normal storage conditions. Its pH in solution can vary depending on the concentration, generally ranging from 5.5 to 7.5 in a 1% aqueous solution.
Sodium Trimetaphosphate has a wide range of applications across different industries. In the food industry, it is used as a sequestering agent, emulsifier, and stabilizer. It can chelate metal ions such as calcium and magnesium, preventing them from causing precipitation and turbidity in food products. This makes it useful in dairy products, preventing the coagulation of milk and improving the texture of ice cream. In the water treatment industry, it is employed to control the precipitation of scale - forming salts. By binding to calcium and magnesium ions, it helps to keep the water clear and reduces the formation of scale in pipes and equipment. In the detergent industry, it serves as a builder, enhancing the cleaning power of detergents by softening the water and improving the solubility of dirt and stains.
When using Sodium Trimetaphosphate, the dosage needs to be carefully controlled according to the specific application. In food applications, it is usually added in small amounts, typically ranging from 0.1% to 1% of the total weight of the food product. It should be dissolved in water first before being added to the food mixture to ensure uniform distribution. In water treatment, the dosage depends on the hardness of the water. For moderately hard water, a dosage of 5 - 10 ppm (parts per million) is often sufficient. In detergent formulations, it can be added at a concentration of 5% - 15% by weight. It is recommended to mix it thoroughly with other detergent ingredients during the manufacturing process. Safety precautions should be taken during handling. Wear appropriate protective equipment such as gloves and goggles to avoid direct contact with the skin and eyes. In case of contact, rinse immediately with plenty of water and seek medical advice if necessary.
Industria alimentaria: A dairy company was facing issues with the coagulation of milk during the production of yogurt. They added Sodium Trimetaphosphate at a concentration of 0.3% to the milk before the fermentation process. The result was a significant improvement in the texture of the yogurt, with a smoother and more consistent appearance. The yogurt also had a longer shelf - life as the sequestering action of Sodium Trimetaphosphate prevented the growth of certain bacteria that are sensitive to metal ions. Tratamiento del agua: A power plant was experiencing severe scaling in its cooling water system, which was reducing the efficiency of the heat exchangers. After adding Sodium Trimetaphosphate at a dosage of 8 ppm to the cooling water, the formation of scale was significantly reduced. The heat transfer efficiency improved, leading to energy savings and a decrease in maintenance costs. Detergent Industry Case: A detergent manufacturer was looking to improve the performance of its laundry detergent. By adding Sodium Trimetaphosphate at a concentration of 10% to the detergent formula, the detergent was able to remove dirt and stains more effectively, especially in hard - water areas. The product received positive feedback from consumers, leading to an increase in sales.
