Sodium Tripoly Phosphate (STPP)
₹92 – ₹173
Sodium tripolyphosphate (STPP), also known as sodium triphosphate, is the sodium salt of triphosphoric acid. STPP is a colorless salt that exists both in anhydrous form Na5P3O10 and in hexahydrate form H12Na5O16P3. It is frequently used as a food preservative and as a water softener in commercial detergents. As a food additive, STPP helps with moisture retention and is used to preserve the natural color of meat and fish products while improving their texture. It acts as an emulsifier and helps to prevent meat, poultry, or fish from becoming greasy and falling apart during heating. STPP is commonly used in meat and dairy processing. In cleaning products, STPP improves the ability of detergents to penetrate fibers and other materials. It also aids in foaming, and its pH buffering ability makes it useful as a water softener. Many household cleaning products such as kitchen and bathroom cleaners contain STPP.
Sodium tripolyphosphate (STPP) is a chemical compound with the formula Na5P3O10. It is a type of polyphosphate, which is a chain of phosphate units. Here are some key points about sodium tripolyphosphate:
- Chemical Structure: STPP consists of three phosphate groups (PO4) linked together in a chain, forming a triphosphate unit. The sodium ions (Na+) balance the negative charges of the phosphate groups.
- Physical Properties: STPP is usually found as a white, crystalline powder or granules. It is highly soluble in water.
- Uses:
- Detergents: One of the primary applications of STPP is in the manufacturing of detergents. It helps in softening water, preventing the formation of mineral deposits on clothes, and enhancing the effectiveness of cleaning agents.
- Food Industry: STPP is used in the food industry as a preservative and sequestrant. It can be added to seafood to retain water and improve texture. However, its use in food has decreased in some regions due to environmental concerns and potential health issues.
- Water Treatment: STPP is employed in water treatment processes to inhibit the formation of scale deposits and control the corrosion of metal surfaces in pipes and equipment.
- Industrial Applications: It is used in various industrial processes, including metal treatment and as a builder in some formulations like ceramics and paints.
