What is STPP?

STPP is an inorganic compound with a white colour and can exist in the form of granules or crystals. It is highly soluble in water, resulting in the formation of an alkaline solution. This compound is derived through a manufacturing process that involves neutralizing a phosphoric acid solution using sodium hydroxide and sodium carbonate. The chemical formula of STPP is Na5P3O10, representing the sodium salt of the polyphosphate penta-anion.

STPP finds extensive applications in various domestic and industrial products, particularly in the formulation of detergents. Its alkaline properties and solubility in water make it an effective ingredient for cleaning purposes. Additionally, STPP is utilized in the food industry as a preservative and emulsifier, as well as in water treatment processes and ceramic production.

Properties of STPP

STPP, also known as sodium tripolyphosphate or STP, is an inorganic compound with the chemical formula Na₅P₃O₁₀. It is a white, crystalline powder that is highly soluble in water. Here are some properties of STPP:


STPP is highly soluble in water, which means it easily dissolves in water to form a clear solution. This property makes it suitable for various applications where water-based solutions are required.


STPP is alkaline in nature and has a high pH. In aqueous solutions, it can act as a buffering agent, helping to maintain a stable pH level.

Chelating Agent

STPP is an effective chelating agent, meaning it has the ability to bind to metal ions. It forms complexes with metal ions, preventing them from interfering with various processes such as detergency and corrosion control.

Detergent Properties

STPP is commonly used in detergents and cleaning products due to its ability to soften water, enhance cleaning efficiency, and prevent the redeposition of dirt and stains on fabrics.

Water Treatment

STPP is utilized in water treatment processes to prevent the formation of scale and to control the levels of certain metal ions. It helps to inhibit the precipitation of calcium and magnesium ions, which can cause scaling in pipes and equipment.

Food Additive

STPP is approved as a food additive in some countries. It is used as a preservative, emulsifier, and sequestrant in various food products. However, its use as a food additive is subject to regulations and restrictions.
