Phosphates have the ability to sequester calcium and it may form calcium phosphate so it poses some risk to people with kidney stones. Sodium metaphosphate leads to growth retardation in rats.  It is used as an oral care agent. Sodium polyphosphates induce kidney damage and act as a skin irritant. Irritation is a function of concentration. It leads to the enlargement of parathyroid glands*. It may cause gastrointestinal tract irritation and may cause nausea, vomiting, and diarrhea. High concentrations of phosphates may disturb several metabolic processes as phosphate plays an important role in general metabolism.
