Type of information:
other: Data obtained from a collection of reliable data
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data

Type:
relative density
Density:
0.95 g/cm³
Temp.:
25 °C

The AIChE DIPPR Database specifies that the uncertainty associated with the density value for octamethylcyclotetrasiloxane at 25 ºC as <1%.

Conclusions:
A density value of 0.95g/cm³ at 25°C was reported in a handbook or collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable.

Description of key information

Density [octamethylcyclotetrasiloxane]: 0.95 g/cm3 at 25°C

Key value for chemical safety assessment

Relative density at 20C:
0.95

Additional information

A density value of 0.95 g/cm³ at 25°C was reported in a collection of reliable data which has been subject to peer-review and in which the original data sources are traceable. The result is considered to be reliable and selected as key study. This value is supported by a relative density of 0.96 at 20°C reported for the substance in a handbook or collections of reliable data subject to peer-review. In a secondary source to which reliability could not be assigned, density value of 0.95 g/cm3 at 20°C was reported for the substance.
