Endpoint:

relative density

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

Principles of method if other than guideline:

Interpolation from temperature-density correlation.

GLP compliance:

no

Type of method:

other: temperature-density correlation

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.
