Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There are no toxicity data for soil organisms relating to 2 -tetradecyloctadecan-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.

A reliable study show that 2 -tetradecyloctadecan-1 -ol is readily biodegradable. Biodegradation of long-chain alcohols will not produce degradation products of concern, as reported in a study by Federle and Itrich (2006) where long chain alcohols rapidly decayed in water treatment processes. The half-lives of all the long chain alcohols tested were less than one minute and the removal in activated sludge plants of long-chain alcohols, such as hexadecanol, are reported to be 99.46%.

In the environment, ready biodegradability means it can be assumed that 2 -tetradecyloctadecan-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. Furthermore, for substances not passing the STP-process but being readily biodegradable, it can be assumed that they will be also biological degraded in the surface water within a short time. Therefore, no tests on terrestrial organisms are provided.
