Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
distribution modelling
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Study period:
n/a
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: This robust summary was given, a reliability rating of 2, because the data are not measured values for the product listed, but are calculated for representative constituents.
Cross-reference
Reason / purpose for cross-reference:
read-across: supporting information
Reference
Endpoint:
distribution modelling
Type of information:
read-across from supporting substance (structural analogue or surrogate)

Distribution modelling results are included in the 'Multimedia distribution modeling results' tab in the PETRORISK spreadsheet attached to Section 13 of the CSR. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 96 % to air, 1.4 % to water, 1.3 % to sediment and 0.077 % to soil.

Conclusions:
The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model, version 5.2. Based on the regional scale exposure assessment, the multimedia distribution of the substance is 96 % to air, 1.4 % to water, 0.077 % to soil and 1.3 % to sediment. Distribution modeling results are included in the 'Multimedia distribution modeling results' tab in the PETRORISK spreadsheet attached to IUCLID section 13.
Executive summary:

This data is being read across from the source study that tested Hydrocarbons, C9-C12, n-alkanes, isoalkanes, cyclics, aromatics (2-25%) based on analogue read across.

The distribution of the substance in the environmental compartments, air, water, soil, and sediment, has been calculated using the PETRORISK Model, version 5.2. Computer modeling is an accepted method for estimating the environmental distribution of chemicals. Distribution modeling results are included in the 'Multimedia distribution modeling results' tab in the PETRORISK spreadsheet attached to IUCLID section 13.
