Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- QSAR estimation using the Estimation Programs Interface (EPI) SuiteTM v4.1 containing the ECOlogical Structure Activity Relationship (ECOSAR) software, the substance falls within the applicability domain

Key value for chemical safety assessment

Fresh water invertebrates

Fresh water invertebrates
Effect concentration:
6 070 000 mg/L

Additional information

Based on the reliable estimation using the Estimation Programs Interface (EPI) SuiteTM v4.1 containing the ECOlogical Structure Activity Relationship (ECOSAR) software, which reveals a LC50 value which is clearly above the limit concentration of 100 mg/L and further mitigating factors which indicate that the substance unlikely causes ecotoxicological effects, i.e. no toxic effects to algae up to the limit concentration of 100 mg/L, L-Asparagine is not considered to generate toxic effects up to the limit concentration of 100 mg/L.
