Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Conclusion on classification
The following relevant hazard information was used for the environmental classification and labeling:
- The substance is readily biodegradable (mean of 83% degradation in 28 days) in the Modified Sturm test (OECD 301B)
- The partition coefficient (logKow) was estimated to be lower than -4
- The acute toxicity test for fish (OECD 203) with the read-across substance L-Glutamic acid (EC# 200-293-7) revealed an 96h-LC50 exceeding an analytically confirmed nominal concentration of 100 mg/l.
- The Daphnia sp. acute immobilization test (OECD 202) with the read-across substance L-Glutamic acid (EC# 200-293-7) revealed an 48h-EC50 exceeding an analytically confirmed nominal concentration of 100 mg/l.
- The alga growth inhibition test (OECD 201) with the registered substance revealed a 72h ErC50 exceeding the range tested (> Time Weight Average (TWA) concentration of 2 mg/L), a NOECr of 0.24 mg/L based on TWA concentrations and a calculated 72h ErC10 of 1.3 mg/L based on TWA concentrations.
As the EC50 values for the three trophic levels were > 1 mg/L, the substance should not be classified for acute aquatic hazard.
For the classification assessment into long-term aquatic hazard, the ErC10 of the algae growth inhibition test was used as preferred chronic toxicity value (reference is made to the Guidance on the Application of the CLP Criteria, Version 4.0 (November 2013), section 4.1.3.1.1., footnote 88).
As the calculated ErC10 value is exceeding the cut-off value of 1 mg/L for long-term classification of rapidly degradable substances, the substance does not need to be classified.
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.
