Application:
Disodium phosphate dihydrate (DSP), also known as sodium phosphate dibasic dihydrate, has several applications in the food processing, pharmaceutical, and personal care industries. Here are some typical applications:
1. Food processing: Disodium phosphate dihydrate (DSP) is an additive in various processed food products. It acts as a pH regulator, emulsifier, and texturizer. It helps enhance flavor, improve texture, prevent spoilage, and stabilize acidity or alkalinity in food items such as breakfast cereals, cheese, processed meats, and dairy products.
2. Pharmaceutical industry: Disodium phosphate dihydrate (DSP) is used as a buffering agent, pH adjuster, and excipient in several medications. It helps control and maintain the pH of formulations, ensuring the stability and effectiveness of drugs. It is commonly found in tablets, capsules, and liquid medications.
3. Personal care industry: Disodium phosphate dihydrate (DSP) can be found in certain personal care products, such as shampoos, conditioners, and creams. It acts as a pH adjuster, helping to ensure the optimal pH for the desired product performance and stability.
