Release to the environment of Tetrasodium pyrophosphate (TSPP) can occur from industrial use: manufacturing of the substance, formulation of mixtures, formulation in materials, in processing aids at industrial sites, in the production of articles and as an intermediate step in further manufacturing of another substance (use of intermediates).
Tetrasodium pyrophosphate (TSPP) also called TSPP is used as a buffering agent, emulsifier, dispersing agent, and a thickening agent in chicken nuggets, marshmallows, pudding, crab meat, imitation crab, canned tuna, and soy-based meat alternatives|and cat foods and cat treats|in dental hygiene products such as toothpaste, dental floss, commercial dental rinses and household detergents.

Primarily used as a food additive tetrasodium pyrophosphate (TSPP) is a salt composed of pyrophosphate and sodium ions that possesses approximately twice the toxicity of table salt when ingested orally.
In general use, Tetrasodium pyrophosphate (TSPP) is used as an emulsifier, thickening agent, buffering agent, and a dispersing agent.
Chicken nuggets, crab meat, marshmallows, imitation crab, pudding, canned tuna, and numerous soy-based meat alternatives use Tetrasodium pyrophosphate (TSPP), as do cat food and cat treat manufacturers to make their products more palatable to felines.

Tetrasodium pyrophosphate (TSPP) also functions as a tartar control agent in both dental floss and toothpaste by removing the calcium and magnesium found in saliva to prevent them from forming deposits on teeth.
Most Tetrasodium pyrophosphate (TSPP) is synthesized via the reaction of furnace-grade phosphoric acid and sodium carbonate in order to produce disodium phosphate, which is then heated to a temperature of 450 degrees C to form TSPP.
Another common method of synthesis is the molecular dehydration of dibasic sodium at 500 degrees C.
