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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Adsorption coefficient (log Koc) for GLDA-H4 was calculated to be -1.93 (QSAR). The log Koc for the read across substance GLDA-Na4 was determined to be <1.5 (HPLC, OECD TG 121).
Key value for chemical safety assessment
- Koc at 20 °C:
- 0.012
Additional information
The adsorption coefficient (Koc) of GLDA-Na4 was estimated using the High Performance Liquid Chromatography (HPLC) method. The average measured Koc value for GLDA-Na4 in the ionized form (pH 2) as well as in the nonionized form (pH 7) as calculated from the test is < 32 (Log Koc < 1.5). Log Koc for GLDA-H4 calculated with QSAR was -1.93. This indicates that both GLDA-H4 and GLDA-Na4 will be mobile in soil and not be sorbed by sludge in a sewage treatment plant.
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.
