Sodium Tripolyphosphate

Sodium Tripolyphosphate, also referred to as Pentasodium Triphosphate or STPP is a sodium salt of triphosphoric acid. It appears as either white powder, crystals or granules and is soluble in water.  This material is manufactured in large volumes by heating a mixture of disodium phosphate and monosodium phosphate.

Offering several commercial and industrial uses, sodium tripolyphosphate usage is highest within the cleaning products and detergents markets. The addition of STPP allows cleaning agents to perform efficiently within a variety of conditions and temperatures. It also acts as a water softener and assists in the control of scale.

Other uses of sodium tripolyphosphate include within the food industry under E number E451. It improves the water retention of meat and fish products to improve texture, enhance appearance and slow down the natural drying/spoiling process of meat.

Sodium Tripolyphosphate is also used as a tanning agent for leather, a pH adjuster in water treatment, and has uses within the paper and pulp industries.
