Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

The relative density (compared to water at 4°C) was: DR4 = 1.57

Conclusions:
Under the study conditions, the relative density of the substance was determined to be 1.57 at 21.5°C.
Executive summary:

A study was conducted to determine the relative density of the read across substance Reaktiv Scharlach F97 -0319 according to EU Method A.3, in compliance with GLP. The air comparison pycnometer (for solids) was used in this experiment. The volume of a substance is measured in air or in an inert gas in a cylinder of variable calibrated volume. For the calculation of density, one mass measurement is taken after concluding the volume measurement. Two test series with different weights were carried out in air. Under the study conditions, the relative density of the substance was determined to be 1.57 at 21.5°C (Hoffmann, 1999).

Description of key information

The relative density was determined according to EU Method A.3 (Hoffman, 1999).

Key value for chemical safety assessment

Relative density at 20C:
1.57
