Description of key information

Adsorption to solid soil phase is not expected.

Key value for chemical safety assessment

Additional information

In accordance with Annex VIII, Column 2 a study on adsorption/desorption study does not need to be conducted if based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient). The very low log Pow of 2.76 measured for the substance indicates that the substance has a low potential for adsorption.

Furthermore the soil sorption coefficient Koc of citral was calculated using EPIWIN v3.12, PCKOCWIN v1.66. The calculation yielded a Koc=147.7. Taking into account the classification of Blume & Ahlsdorf (1993), a low sorption of citral onto soil organic matter is to be expected.
