Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Biodegradation in water and sediment, simulation test:
The PETRORISK model (version 7.04) predicted degradation half-lives in surface water and sediment for constituents of this substance range between 1.0 and 165,496 days and 4.1 and 661,986 days, respectively.
Biodegradation in soil:
The PETRORISK (version 7.04) predicted degradation half-lives in soil for constituents of this substance range between 1.0 and 165,496 days.
QSAR predictions of half-lives of HFO have also been provided to support the read-across from HFO to registration substance.
Additional information
Substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. Standard biodegradation studies are not applicable to petroleum UVCB substances. However, this endpoint is characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see Product Library in PETRORISK report attached to IUCLID Section 13). PETRORISK is a well documented and peer reviewed model that is widely used across the petrochemicals industry. This substance fits within the criteria of the model and there are no reservations about the validity of the model runs. It is expected that this data is reliable with restrictions.
It should be borne in mind that this is the full range of predicted values, and that this may be misleading or unrepresentative of the properties of the UVCB substance as a whole. The range should therefore be treated with caution and not taken out of context. The substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance.
For purposes of PBT assessment, the substance has been assessed using a combination of QSAR predictions and confirmatory experimental testing for representative constituents using a hydrocarbon block approach. For details see report titled 'Evaluation of PBT for Petroleum Substances' in IUCLID section 13.
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.
