Sodium Tripolyphosphate (STTP)

Sodium tripolyphosphate (STPP) is widely used as a key ingredient in synthetic detergents, providing benefits like hard water sequestration, soil emulsification, and pH buffering.

It also functions as a food additive in products like processed meats to improve water-holding capacity and is used in industrial applications such as water treatment, ceramics, paper making (de-inking), and metal cleaning.

Cleaning products

Detergents: A major component in both laundry and automatic dishwashing detergents. It softens water by sequestering calcium and magnesium ions, which helps surfactants work more effectively.
Surface cleaners: Used in various household and industrial surface cleaners.
Soap: Acts as a synergist for soap, preventing grease precipitation.

Food industry

Meat and seafood processing: Enhances water retention and tenderness in processed meats, poultry, and seafood, which can prevent shrinkage during cooking.
Quality improver: Increases ionic strength and improves water-holding capacity in foods.

Industrial applications

Water treatment: Softens water for industrial boilers, power stations, and cooling systems, preventing the formation of scale.
Paper manufacturing: Used in the de-inking process of recycled paper to help disperse ink particles.
Ceramics: Acts as a deflocculant, which reduces the viscosity of clay slurries.
Coatings: Used in paints and coatings, and as a component in drilling muds.
Construction: Can be used as a retarder in gypsum board production and to improve the workability of concrete.
Metal treatment: Utilized for cleaning and preparing surfaces before painting.

Sodium Tripolyphosphate (STTP) Other uses

Textile dyeing: Used as a dispersing agent.
Pharmaceuticals: Can be included as an inactive ingredient (excipient) in some tablet formulations.

Sodium Tripolyphosphate, is used as a preservative for poultry, meat, and seafood.
It is also added, along with other sodium polyphosphates, to processed cheeses as an emulsifier.
The polyphosphates are negatively charged chains of phosphorus and oxygen that attract water molecules.
