Q: Tetrapotassium Pyrophosphate Application?
A: 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 TKPP is classifed as a buffering, chelating and oral care agent. Tetrapotassium pyrophosphate is the "tartar control" agent which removes calcium and magnesium from the saliva, so they can not deposit on the teeth.Potassium pyrophosphate is mainly used in toothpastes and mouthwash formulations. Tetrapotassium pyrophosphate is used as an anionic dispersant in water-based paints. It removes a small amount of Fe 3 + in order to improve the quality of dyeing.
TKPP is a soap and detergent builder. tetrapotassium pyrophosphate is a water softener and an emulsifier to suspend oils and prevent them from redepositing on clothing in the wash. As a water softener, TKPP combines with magnesium to sequester it from the detergent, without precipitating it onto the clothing. As a detergent additive, potassium pyrophosphate 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.

Phosphates are basically compounds of phosphorus and oxygen that occur in many forms and are usually combined with other elements. We offer a wide range of phosphate compounds such as PHOSPHRIC ACID, POTASSIUM PYROPHOSPHAYE,SODIUM HEXAMETAPHOSPHATE.
