Description of key information

Boiling Point (1,1,3,3-tetramethyldisiloxane): 70.3°C (OECD 103)

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
70.3 °C

Additional information

A measured boiling point of 70.3°C was determined for the substance using a relevant test method. Although full details are not available, the result is considered to be reliable and was selected as key study. This value is supported by a predicted boiling point of 100°C which was determined using a validated QSAR estimation method. In a secondary source, a boiling point of 71°C was reported for the substance, no further information is available and the reliability is unassignable.
