  • Calcium carbonate (CaCO3) - 17%;
  • Calcium chloride (CaCl2) - 12%;
  • Calcium sulphate (CaSO4) - 14%;
  • Magnesium carbonate (MgCO3) - 4%;
  • Potassium orthophosphate (K3PO4) - 13%;
  • Magnesium sulfate (MgSO4) - 4%;
  • Magnesium silicate (MgSiO3) - 4%;
  • Sodium chloride (NaCl) is 0.5%;
  • Orthophosphate sodium (NaPO4) - 15%.
