Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
There are no toxicity data for soil organisms relating to 2-hexyldecan-1-ol or other long chain alcohols >=C16 in length.
In Annex X of Regulation (EC) No 1907/2006, it is laid down that long-term toxicity to terrestrial organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on terrestrial organisms. Column 2 of Annex X states that studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.
The test substance is not supposed to be applied directly to soil. Indirect exposure to soil via sewage sludge transfer is unlikely since the substance is readily biodegradable. Reliable measured data demonstrate that Guerbet Alcohols of chain lengths at least up to C32 are readily biodegradable. Experimental data provided in CSR Chapter 5 shows that the 10-day window pass level was reached for ready biodegradability with removal levels of up to 96% for carbon chain lengths of C16. In the environment, ready biodegradability means it can be assumed that 2-hexyldecan-1-ol will be biodegraded within the STP process and as a consequence a transfer to the soil compartment via sewage sludge is not expected. Therefore, no tests on terrestrial organisms are provided.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
