Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Flammability on contact with water: Enzymes are easily soluble in water and from experience of handling enzymes together with consideration of the structure of enzymes it can be concluded that enzymes are not flammable on contact with water. 
Pyrophoricity: As they are proteins produced by fermentations, i.e. usually in solution, enzymes are not pyrophoric. In the pure, lyophilized form, they might be pyrophoric, but will in such case only exist in very small quantities for research purpose.

Key value for chemical safety assessment
