EC number: 265-078-2
CAS number: 64741-77-1
A complex combination of hydrocarbons from distillation of the products from a hydrocracking process. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C10 through C18, and boiling in the range of approximately 160°C to 320°C (320°F to 608°F).
Standard adsorption/desorption 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. Full
justifications for this QSAR are presented in 'Attached justification',
but in brief these are justified because:
- the results are obtained from a QSAR model whose scientific validity
has been established
- petroleum substances fall within the applicability domain of the QSAR
- results are adequate for the purposes of risk assessment
- adequate and reliable documentation is provided
Calculated log Koc for constituents of this substance range between 1.71
- 14.70. It should be borne in mind that this is the full range of
predicted values, and that this may be misleading or unrepresentative of
the properties of the UVCB substance as a whole. The range should
therefore be treated with caution and not taken out of context. 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 IUCLID section 13).
