Tetrapotassium pyrophosphate (TKPP) is in the form of colourless or white crystals, or a white crystalline or granular powder. It is a hydroscopic solid, soluble in water, insoluble in ethanol. TKPP has a higher solubility in water treatment formulations than sodium derivatives. Applications: COSMETICS Tetrapotassium pyrophosphate is classifed as a buffering, chelating and oral care agent. It is the "tartar control" agent which removes calcium and magnesium from the saliva, so they can not deposit on the teeth. It is mainly used in toothpastes and mouthwash formulations. PAINTS Tetrapotassium pyrophosphate is used as an anionic dispersant in water-based (latex) paints. It removes a small amount of Fe 3 + in order to improve the quality of dyeing. HOUSEHOLD TKPP is a soap and detergent builder. It is a water softener and an emulsifier to suspend oils and prevent them from redepositing on clothing in the wash. As a water softener, it combines with magnesium to sequester it from the detergent, without precipitating it onto the clothing. As a detergent additive, it can also "reactivate" detergents or soaps that have combined with calcium to make an insoluble scum. Because of the eutrophication of water it is seldom used as a detergent additive. Other uses: Applications in boiler descaling, mining of ore and clay, synthetic rubber production, oil-drilling muds, fabric printing. Texturizer, metal cleaner, sequestering agent, tissue modifier, chelating agent in non-cyanide electroplating,dispersion agent for ceramic, clay, latex and pigments and stabilizer in bleaching leather products.

Relative to the calcium and sodium salts, potassium phosphates constitute a smaller class of inorganic phosphate chemicals. Of these, TKPP is the predominant product. Commercial production of TKPP and other potassium phosphates is based on industrial phosphoric acid and potassium hy-droxide as raw materials. Capacities of production facilities are flexible since producers can manufacture varying amounts of other potassium phosphates using the same equipment. Rhodia acquired Albright & Wilson in 2000, making it the world’s leader in specialty phosphates. To gain Federal Trade Commissions’s consent for the deal, Rhodia divested Albright & Wilson’s merchant phos-phoric acid business in the US to Potash Corp. of Saskatchewan, Albright & Wilson’s former partner in the business. Upon closing of the transaction, the partnership was renamed PCS Purified Phosphates. At about the same time, FMC Corp. and Solutia Inc. announced their formation of Astaris, a 50-50 phosphorus joint venture. The joint venture included FMC’s Carteret, N.J., plant and Solutia’s Augusta, Ga., TKPP facility. Later the same year, Astaris sold the Augusta plant to Prayon. Prayon Inc. is a subsidiary of Prayon-Rupel (Engis, Belgium). Profile last published 4/29/02; this revision 5/9/05.TKPP is the dominant detergent builder product in industrial and institutional (I&I) cleaners, which accounts for 47 percent of its demand. Though, TKPP consumption in the I&I market has declined marginally since 1984, this market segment is now long stabilized and is growing modestly. TKPP for water treatment, its second-largest segment, is at a price disadvantage to sodium phosphates because of the higher cost of the potassium salts. But, potassium phosphates have higher water solubility than the corresponding sodium salts, so they are useful where solids build-up is to be avoided--such as closed circuit cooling systems. TKPP is used in conjunction with in-situ produced orthophosphates in corrosion protection formulations for these cooling water systems. The water treatment market for potassium phosphates has been growing steadily since the mid-1980s and is expected to continue to grow. However, TKPP's growth is mitigated somewhat by polymeric water treatments in an effort to limit phosphate discharge into the environment. TKPP is used in both anti-tartar dentifrice and mouthwash formulations. The estimated consumption in 2004 was 1.3 thousand short tons for these applications. Future demand in this market is expected to follow population growth.Tetrapotassium Pyrophosphate (K4O7P2) is a sequestering agent, highly soluble in aqueous solutions with excellent deflocculating/dispersion properties. Applications of tetrapotassium pyrophosphate include detergents. Potassium pyrophosphate (K4P2O7) is a water soluble, buffering and chelating agent. It can also be used as an ionic dispersant to form a low viscous solution.It is a biocompatible and a non-toxic compound that is commonly used as a food additive. K4P2O7 can be used in the preparation of an electrolytic solution, which can further be used in the fabrication of lithium ion batteries and arrays of copper nanowires. Tetrapotassium Pyrophosphate, Anhydrous (TKPP) Powder is a hygroscopic, white, powder. It is used for its properties as a buffering agent, dispersing agent, protein modifier, coagulant, sequestrant, and mineral supplement. In pet food, TKPP is used to modify proteins enabling them to solubilize and retain moisture during storage. TKPP also increases shelf life of products by sequestering multivalent cations responsible for lipid oxidation and rancidity development. TKPP helps to buffer the pH of the cheese and interacts with the milk protein to promote emulsification. In flavored milk powders, liquid TKPP can be added to the wet ingredient mix prior to spray drying. The TKPP will stabilize and disperse the proteins during drying. In addition the use of TKPP will improve the overall viscosity, smoothness, and flavor of the final beverage. In meat processing, this product enhances moisture retention without increasing sodium content.Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat Symptoms may be delayed.

Wash away remainder with plenty of water. Tetrasodium pyrophosphate and disodium pyrophosphate are the anti-tartar ingredients in Crest Whitening Expressions. They are normal components of human body fluids, are used in many foods, and they have a GRAS (Generally Recognized as Safe) rating from the FDA. These ingredients prevent the formation of crystals that can eventually become. Immediately flush with flowing water until material is removed.

It keeps the freshness, holds water and improves the quality of quick-frozen marine products. TKPP can be applied to prevent the struvite of canned seafoods and the discoloration of fruit products, to improve ice cream swelling rate or the taste of noodle and cake, and prevent the cheese aging. It is used as a pH buffer and as a dough conditioner in soy-based "meat alternatives", chicken nuggets and imitation crab and lobster products. Tetrapotassium Pyrophosphate is a thickening agent in instant puddings.Tetrapotassium pyrophosphate can be found in herbicidal compositions as a spray adjuvant That adjuvant serves as both a plant nutrient and surface-active agent and functions synergistically with the herbicide to increase its level of absorption into plant tissues and to stimulate both the target and non-target plant species to growth responses for increased herbicide efficacy.Tetrapotassium pyrophosphate is classifed as a buffering, chelating and oral care agent.

It also possesses a higher solubility in water treatment formulations than sodium derivatives. Primarily used as an emulsifier, metal ion chelating agent, and quality improver, TKKP maintains freshness, holds water, and improves the quality of flash-frozen marine products. It is also used in the food industry to prevent struvite formation in canned seafoods, the discoloration of canned fruit products, improve the swelling rate of ice cream, improve the taste of noodles and cake, and prevent cheese from aging. In agriculture, TKKP is used in herbicidal compositions as a spray adjuvant that allows for better nutrient absorption in desired plant species and inhibits the nutrient absorption in unwanted plant species. TKKP is also used in the cosmetics industry as a buffering, chelating, and oral care.
