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.
