Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

To fulfill the endpoint adsorption/desorption screening, the adsorption coefficient (Koc) of L-glutamic acid diacetic acid tetrasodium salt (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), indicating that GLDA-Na4 will be mobile in soil and not be sorbed by sludge in a sewage treatment plant.

No further data on transport and distribution is required as the substance is readily biodegradable.
