TKPP is the dominant detergent builder product in industrial and institutional (I&I) cleaners, which accounts for 47 percent of Tetrapotassium Pyrophosphate 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, Tetrapotassium Pyrophosphate 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.
