Sodium tripolyphosphate is an inorganic compound with the chemical formula Na5P3O10, that is largely used as a component for the production of synthetic detergents, water treatment, ceramics, paint, varnish, and also in various other industries. The use of STPP in detergents reduces the formation of lumps and maintains desired flow rate. The Sodium Salt of Triphosphoric acid is a colorless salt and exists in two forms - Anhydrous (Na5P3O10) and hexahydrate form (H12Na5O16P3).Packing :
The most common use of STPP is as a food preservative and as a water softener in commercial detergents.
STPP helps with moisture retention, and so it is extensively used to preserve and improve the texture and natural color of meat and fish products.
It protects and prevents meat, poultry, or fish from becoming greasy and breaking during high temperatures.
The detergent industry and other industries producing bathroom and kitchen cleaners use STPP as a component to improve the effectiveness. It helps detergents to penetrate fibers efficiently, aids foaming, and its pH buffering ability makes it a highly efficient water softener.
STPP is also used as a sequestrant for alkaline metals, pulp, and paper production, tartar control agent, corrosion control, lead control, leather tanning agent, and whitening agent.
