Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

The densities have been determined for a wide range of different proteins, and this analysis showed that the density range is between 1.32 to 1.42 g/mL.

Since the enzyme is a protein it is assumed that it has density within this range.

Key value for chemical safety assessment

Relative density at 20C:

Additional information

We report the average value of 1.37 g/mL as a representative value of the density. It should, however, be noted that the uncertainty is expected to be in the order of +/- 0.05 g/mL.
