Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

Adsorption / desorption GS180:

The substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. 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 spreadsheet attached to Section 13).

Henry’s Law constant GS180:

Volatilisation is dependent on Henry’s Constant (HC) which is not applicable to complex substances. However, HC values for representative constituents have been calculated based on estimated physicochemical data for the constituents. The HC of the constituents ranges from -0.59 to 0.31 atm-m3/mol

Distribution modelling GS180:

The distribution of Hydrocarbons, C9-C11, n-alkanes, isoalkanes, <2% aromatics in the environmental compartments air, water, soil, and sediment has been calculated using the PETRORISK Model, version 7.04. Computer modelling is an accepted method for estimating the environmental distribution of chemicals. Based on the regional scale exposure assessment, the multimedia distribution of Hydrocarbons, C9-C11, n-alkanes, isoalkanes, <2% aromatics is 80 % to air, 4.4% to water, 2.5% to soil and 13 % to sediment. Distribution modelling results are included in the 'Multimedia distribution modelling results' tab in the PETRORISK spreadsheet attached to IUCLID section 13.
