Type of information:
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
See attached QMRF/QPRF
Principles of method if other than guideline:
The result was obtained using an appropriate QSAR method (see attached QMRF and QPRF for details).

The model for density has been developed for, and applies specifically to, organosilicon compounds. It is a multiple linear regression based model with descriptors representing counts of different atoms and groups that may be present in the molecule.
Key result
1.12 g/cm³
20 °C
A density value of 1.12 g/cm3 at 20°C has been determined for the substance using an appropriate estimation method. The result is considered to be reliable.

Description of key information

Density:  1.12 g/cm3 at 20°C (QSAR)

Key value for chemical safety assessment

Additional information

A density value of 1.12 g/cm3 at 20°C was obtained for the substance using a validated QSAR estimation method. The result is considered to be reliable and is selected as key study.

In a handbook or collections of reliable data, density value of 1.1866 g/cm3 at 20°C was reported for the substance.
