Absorption, Distribution and Excretion

If ingested in large amounts nausea, vomiting and diarrhea are probable. Thought to be hydrolyzed to (ortho)phosphates before absorption. If appreciable amounts of the intact polymer are absorbed from the alimentary tract, hypocalcemic tetany may be a danger due to the binding (chelation) of ionized calcium. Hypocalcemic tetany apparently occurred in one ingestion episode. Tripolyphosphate
