Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
As stated in section 5.2.1, reliable studies (Klimisch score 2) were performed in accordance with OECD Guideline 301B (Ready Biodegradability: CO2 Evolution Test) on two primary constituents of olefines polymer, oxidized, hydrolyzed, distillation residues, icosan-1-ol and docosan-1-ol. 88.4% and 87.9% of icosan-1-ol and docosan-1-ol respectively degraded after 28 days with an unacclimated sewage sludge inoculum. The test substances also achieved 60% degradation within the 10-day window indicating ready biodegradability. In two reliable studies by Flach (2012), the degradation of 2-decyltetradecanol and docosan-1 -ol were 84.9% and 87.5%, respectively, after 28 days with the degradation rate reaching more than 60% within the 10-day window. As these constituents are readily biodegradable, olefines polymers, oxidized, hydrolyzed, distillation residues can also be regarded as readily biodegradable. Minor residual constituents which include ethers and esters are also expected to degrade rapidly. It should be noted that these minor residual constituent degradation products of olefines polymer, oxidized, hydrolyzed, distillation residues are unlikely to be chemicals that might be a cause for concern.
According to Annex IX Column 2 of Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals an absorption/desorption study does not need to be conducted if the substance and its relevant degradation products decompose rapidly.
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.
