Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 the two primary constituents of Ziegler Bottoms, 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 innoculum. The test substances also achieve 60% degradation with a 10-day window indicating ready biodegradability. As both constituents are readily biodegradable, Ziegler Bottoms can also be regarded as readily biodegradable. Minor residual constituents which include, ethers, esters and alkanes are also expected to degrade rapidly.

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.
