Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Mid-range chain length alcohols (C11-C13) and longer chain length alcohols (C14 -C15) are reported to have a very high biodegradability (readily biodegradable with extremely high removal in environmentally relevant concentrations; OECD SIDS Long Chain Alcohols, 2006). Longest chain alcohols (>C16) also exhibit significant biodegradation. Thus, long-term effects by Alcohols, C12-18, distn. residues on aquatic organisms are not expected due to quick removal under environmentally relevant conditions, which means long-term exposure to aquatic organisms is unlikely.

Additional information
Toxicity to Aquatic Organisms
Generally the short-term aquatic toxicity of the test substance is low: no effects are expected up to the limit of water solubility for single chain lengths >C13-14 and for some multi-component substances (see OECD SIDS Long Chain Alcohols, 2006).
What is more, mid-range chain length alcohols (C11-C13) and longer chain length alcohols (C14 -C15) are reported to have a very high biodegradability (readily biodegradable with extremely high removal in environmentally relevant concentrations; OECD SIDS Long Chain Alcohols, 2006). Longest chain alcohols (>C16) also exhibit significant biodegradation. Thus, long-term effects on aquatic organisms are not expected due to quick removal under environmentally relevant conditions, which means long-term exposure to aquatic organisms is unlikely.
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.
