Description of key information

PETRORISK model (version 7.04) predicted a log Koc to be between 2.67 and 14.7.

QSAR predictions of adsorption/ desorption of HFO have also been provided to support the read-across from HFO to registration substance.

Key value for chemical safety assessment

Additional information

Standard adsorption/desorption studies are not applicable to petroleum UVCB substances. In accordance with Annex XI Section 1.3 the endpoint has been fulfilled using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks.

PETRORISK (version 7.04) 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.


PETRORISK predicted a log Koc to be between 2.67 and 14.7 (see Product Library results in PETRORISK report attached to IUCLID Section 13).
