Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Under the conditions of the test, endopeptidase batch PPF38268 was found not to be toxic to Daphnia magna at a nominal concentration up to 100 mg TOS/L (24.7 mg aep/L) after 48h exposure. Thus, no 48h EC50 could be calculated and must be > 100 mg TOS/L (> 24.7 mg aep/L).

- The toxicity of trypsin in algae was not tested, however, an enzyme from the same sub-subclass - sedolisin - was tested.

There was no dose-response relationship and because of the low observed toxicity towards algal growth no ErC50 value could be estimated and must be > 100 mg TOS/L (> 24.7 mg aep/L). The NOEC value was determined to be < 10 mg TOS/L (< 2.5 mg aep/L). Due to the similarity between the two enzymes, similar results are expected for trypsin.
