Description of key information

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 characterised 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 in the RSS justification as well as in IUCLID section 13).

The partition coefficient of Hydrocarbons, C10 -C13, n-alkanes, isoalkanes, cyclics, aromatics (2 -25%) in PETRORISK is ca. 4.20
