1. Food & Healthcare Ingredients

• Stabilizer and Emulsifier: Disodium phosphate helps maintain the consistency and texture of processed foods, preventing ingredients from separating and ensuring a uniform product.
• pH Buffer: Disodium phosphate helps maintain the acidity or alkalinity of food products, which can affect flavor, color, and texture, and extends shelf life.
• Moisture Retention: In meat and poultry processing, disodium phosphate is used to retain moisture, making the product more juicy and tender.
• Anti-Caking Agent: Disodium phosphate prevents clumping in powdered food products, such as powdered milk and spices, ensuring a smooth and free-flowing texture.

2. Pharmaceuticals

• Buffering Agent: Disodium phosphate is often used to maintain a stable pH in pharmaceutical formulations, which is crucial for the stability, solubility, and bioavailability of medications.
• Laxative: In the preparation of enemas, disodium phosphate acts as a laxative, drawing water into the intestines to soften stool and stimulate bowel movements.
• Bowel Cleansing: It's used as part of a regimen to clear the bowel before colonoscopy, helping to prepare the colon for examination

3. Water Treatment

• Scale and Corrosion Control: Disodium phosphate helps prevent the formation of scale, which is the buildup of mineral deposits on equipment surfaces, by reacting with calcium and magnesium ions in the water to form insoluble compounds that are easily removed. It also helps control corrosion by forming a protective layer on metal surfaces. It can be used directly for corrosion control or blended with polyphosphates for both corrosion control and scale inhibition.

4. Fabric solutions

• Emulsifier: In some fabric treatments, it can help stabilize mixtures of oil-based and water-based compounds, preventing them from separating. This is particularly important when applying flame retardant finishes or other treatments that involve multiple compounds.
• Buffering Agent: It acts as a buffer, meaning it helps maintain a stable pH level in the bath during dyeing and bleaching. This is crucial for fabrics that are sensitive to pH fluctuations, as drastic changes can damage the fibers or affect the dye absorption.

5. Cleaning & Disinfectants

• Water Softening: Disodium phosphate helps soften water by preventing the formation of calcium scale in boilers and other water systems.
• Scale Control: It acts as a scale controller in various systems, including low-pressure boilers and steam propulsion vessels.
