Documented uses

CIR ingredient: Dipotassium Phosphate
Used as a buffering agent and corrosion inhibitor in anti-freeze, a culture nutrient for the production of antibiotics, a sequestrant, an emulsifier in cheeses, and a buffer in coffee creamers; Also used in specialty fertilizers, paper-processing aids, and saline cathartics; [HSDB] Used as yeast nutrient, humectant, and laboratory reagent; [CHEMINFO]
Pulp and Paper Processing [Category: Industry]
Buffering agent in anti-freeze; nutrient in the culturing of antibiotics
Sequestrant; emulsifier in specified cheeses
Most of the commercial output of dipotassium phosphate is used in conjunction with borates, nitrites, nitrates, and/or silicates as corrosion inhibitor systems in ethylene glycol antifreeze formulations. Its second largest use is as a buffer in coffee creamers to prevent casein protein precipitation by coffee acids. Other uses include specialty fertilizers, paper-processing aids, and saline cathartics.
