Description of key information

Melting point (decamethyltetrasiloxane): <-20°C (Handbooks)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-70 °C

Additional information

Two reliable melting point data are available for the substance. Melting point of -70°C and -76 were reported for decamethyltetrasiloxane in handbooks or collection of reliable data which have been subject to peer review and in which the original sources are traceable. The results are considered reliable and used as weight of evidence. In another secondary source to which no reliability could be assigned, melting point of -100°C was reported for the substance.
