Description of key information

Absorption to solid phase is not expected.

Key value for chemical safety assessment

Koc at 20 °C:
0.024

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.
