Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to the low aquatic toxicity, the PNECaquatic organisms can only be expressed a lower limit (> 7.12 mg/L based on an AF of 10). Due to the low sorption to organic matter an estimation based on the Equilibrium partitioning theory cannot be applied. No PNEC for the sediment compartment was derived because of the low sediment-water partition coefficient. Based on the available terrestrial data, a PNEC of 0.38 mg/kg dw for the soil compartment could be derived. Considering the salty character of GLDA partitioning to air is not considered to be relevant.
Conclusion on classification
No effects were observed in the short term ecotoxicity tests with 100 mg/L test substance (GLDA-Na4). When these results are read across to GLDA-H4, using MW correction, values below 100 mg/L are calculated which would point at a GHS classification of acute 3. But considering the results of the long term daphnia and sac fry test it is very unlikely that acute effects will be observed at 100 mg/L GLDA-H4. Classification for hazards to the environment of GLDA-H4 is therefore not deemed necessary.
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).
