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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Distribution modelling
Administrative data
- Endpoint:
- distribution modelling
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- 27 Aug 2021
- Reliability:
- 2 (reliable with restrictions)
- Justification for type of information:
- Standard biodegradation studies are not applicable to petroleum UVCB substances, therefore in accordance with Annex XI Section 1.3 testing is not scientifically necessary and the endpoint has been fulfilled using QSAR calculations for relevant constituents.
PETRORISK is a well documented and peer reviewed model that is widely used across the petrochemicals industry. The registration 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.

Applicant's summary and conclusion
- Conclusions:
- The distribution modelling of the substance was carried out using PETRORISK version 7.04. The model predicted the distribution of the substances to be as follows; 0.08% to air, 0.01% to water, 34.87% to soil, and 65.05% to sediment.
- Executive summary:
The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model, version 7.04. Computer modeling is an accepted method for estimating the environmental distribution of chemicals. The model predicted the distribution of the subtance to be as follows; 0.08% to air, 0.01% to water, 34.87% to soil, and 65.05% to sediment (see distribution modelling results included in the 'Multimedia distribution' modeling results in the PETRORISK report attached in 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.
