Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The registered substance, Alkenes, C6-11, hydroformylation products, distn. residues, heavy cracked fraction is a UVCB that does not contain constituents that possess a hydrolytically reactive functional group. Therefore, this fate process will not contribute to a measurable degradative loss of this substance from the environment. Further testing is not required under Annex XI, section 1.2. Atmospheric oxidation of aliphatic alcohols and ethers is expected to occur rapidly based on AOPwin v1.92 predictions.
The registered substance achieved 33% biodegradation in 28 d based on results from a standard OECD ready biodegradation test guideline. Studies are not available to assess the biodegradability of the substance under simulated conditions or in soil. In accordance with column 2 of REACH Annex IX, The biodegradation in water and sediments, and the biodegradation in soil simulation tests do not need to be conducted as the chemical safety assessment according to Annex I does not indicate the need to investigate further the degradation of the substance and its degradation products.
In an enhanced OECD 301F test with acclimated sludge, 63% biodegradation of the registered substance was achieved after 28 d. Alkenes, C6-11, hydroformylation products, distn. residues, heavy cracked fraction,
although not readily biodegradible, does not meet the criterion for persistence since biodegradation potential was demonstrated in an enhanced test.
The BMF of the test substance was 1.43. An average BCF of two representative structures with a half-life of 84.4 d was calculated to be 6751.
Adsorption (log Koc) values were calculated for representative constituents of this complex substance. No further testing is needed based on the chemical safety assessment.
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.
