Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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