Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
Substance characterisation
The test substance tetrasodium N,N-bis(carboxylatomethyl)-L-glutamic acid is very well soluble in water and has a very low octanol-water partitioning coefficient (log Kow < 0). Therefore in the environment it is not expected to sorb to organic matter or to accumulate in organic tissue. Thus GLDA-Na4 will remain in the water phase of the water/sediment system and in soil system it will remain in the porewater. GLDA-Na4 is to be considered as a readily biodegradable substance, as was demonstrated in a range of studies; GLDA is anaerobically biodegradable, as demonstrated with a study performed according OECD 311 TG.
Classification and PBT
This means that the substance does not fulfill the criteria for bioaccumulative and persistent (as part of PBT and vPvB) and does not need to be classified as an acute or chronic hazard for the environment according to the CLP criteria, neither will it lead to classification for long-term effects in the environment according to the criteria of the Dangerous Substances Directive.
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.
