Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Justifications and discussions
- Category rationale:
- The vapor pressure of four different enzymes (freeze-dried) was measured using the vapor pressure balance method at temperatures 40-50 °C and 60-70 °C (below denaturing temperature). Several runs were conducted for each enzyme and a mean value was calculated for each enzyme. All four enzymes had vapor pressure in the order of 10^-3 Pa.
This shows that the vapor pressure of enzymes is very similar and can be used as read-across to all other enzymes.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
