Description of key information

The relative density of the test item was determined in a GLP-compliant study performed in accordance with EC A.3 method and OECD Guideline No. 109, using the pycnometer method.

The density of the test item was 1584 kg/m3 at 20°C; the relative density was 1.584 (mean of 2 runs)

Key value for chemical safety assessment

Relative density at 20C:
1.584

Additional information

The relative density of the test item was investigated in one GLP-compliant study performed in accordance with standard methods, without deviations. The study is considered as reliable (Klimisch 1) and is selected as a key study for the endpoint.

A consistent value of 1.6 g/cm3 was reported on Safety Data Sheet of the registrant company. No details on the measurement are available. The value is reported as supporting data.
