Description of key information

Three references are available for the melting point of sodium tripolyphosphate, two of which are peer reviewed handbooks.
All three references give the same value for the melting point (622°C) and therefore using a weight of evidence approach, this value can be taken to fill this endpoint

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
895.15 K
