Tripotassium Citrate Usage Areas:
As a result of excessive acidity, uric acid solubility is very low. As a result, uric acid stones are formed and kidney failure occurs. It is used in the production of drugs used to eliminate such diseases.
It is used to reduce the sensitivity of teeth in the production of oral care products.
It is used as a Flame Retardant in the production of solid wood in forest products.
It is used as a chelating agent and buffering agent in the food and pharmaceutical sector.
It is used as an acid buffer because it contains less sodium than the Trisodium Citrate compound.
It is used in the production of chemicals used to increase bone density in the treatment of osteoporosis.
It is used as a stabilizer in oral solutions in the pharmaceutical industry.
