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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 19 February 2022
- 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 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. 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.

Applicant's summary and conclusion
- Conclusions:
- The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 99.76% to air, 0.19% to water, 0.03% to sediment and 0.02% to soil.
- Executive summary:
The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 99.76% to air, 0.19% to water, 0.03% to sediment and 0.02% to soil. Distribution modelling results are included in the ‘Multimedia distribution modelling results’ in the PETRORISK report attached to IUCLID Section 13 of the CSR.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
