Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Conclusions:
A soil adsorption coefficient of log Koc=1.13 indicates that L-glutamic acid has negligible sorption to soil and sediment. Since the ionisation state of L-glutamic acid is sensitive to pH, the Koc may vary with pH.
