Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

1. CATEGORY HYPOTHESIS
Enzymes and other proteins are polymers built of different combinations of the 20 common amino acids. The sequence and length of the amino acids in the polymer differ between enzymes, and this determines the 3-dimensional structure, the activity and specificity of the enzyme. The physico-chemical characteristics of enzymes are mainly dependent on the amino acids building the enzyme. Since all enzymes are built up of a combination of the same 20 common amino acids, the physical and chemical characteristics will be very similar across different enzymes, but also degradability.
2. CATEGORY JUSTIFICATION
A variety of enzyme classes has been tested for biodegradability and all prove to be readily biodegradable according to OECD 301.
3. APPLICABILITY DOMAIN OF THE CATEGORY
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.
