Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with REACH Annex VIII section 9.3.1. column 2 the study on adsorption/desorption screening (required in section 9.3.1. column 1) does not need to be conducted as the substance has a low log Kow as well as the substance and its degradation products decompose rapidly. Adsorption to solid soil phase is not expected. From the water surface L-glutamine will not evaporate into the atmosphere.

Despite of that Koc was estimated by calculation by EpiSuite's KOCWIN model. The suitability of the model was assessed and it was concluded that L-glutamine is considered to be inside the applicability domain of the EpiSuite KOCWIN model.
