Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

A read across to L-aspartic acid was performed based on the similar chemistry of the 2 substances.  The transcribed value, considering the molecular weights of the 2 substances, is IC50,3h > 338 mg L-aspartic acid/L.

Key value for chemical safety assessment

EC50 for microorganisms:
338 mg/L

Additional information

The inhibition of respiration of microorganisms could be waived, based on the readily biodegradability of L-ASP, which indicates a low toxicity to microorganisms. To obtain a more concrete data a read across was performed to SA.
