- Justification for type of information:
- The registration substance Hydrocarbons, C11-C14, n-alkanes, isoalkanes, <2% aromatics, EC number 701-280-3 (target) and the test substances Hydrocarbons, C10-C14, n-alkanes, isoalkanes, <2% aromatics (source) and Hydrocarbons, C11-C14, n-alkanes, isoalkanes, cyclics, <2% aromatics (source) are all hydrocarbons with many constituents in common. The source substances cover the carbon number range of the target substance. The substances therefore have qualitatively similar properties (RAAF Scenario 2 applies).
