Key value for chemical safety assessment

Additional information

Wash oil did not show a mutagenic potential in the Ames test. No further studies have been performed, as wash oil is considered to be a potential carcinogen based on its quinoline content (see Chapter 5.8. - Carcinogenicity). Quinoline itself has been demonstrated to be positive in various in vitro and in vivo genotoxicity tests.

Short description of key information:
Wash oil produced no mutagenicity in the Ames test. However, due to its content of 3% quinoline (classified as Muta. 2 according to CLP Regulation), wash oil is itself classified as Muta. 2.

Endpoint Conclusion: Adverse effect observed (positive)

Justification for classification or non-classification

Quinoline is classified as Cat. 2 mutagen according to Annex VI, Table 3.1 of Regulation (EC) No 1272/2008 (CLP regulation) as amended by Regulation (EC) No 790/2009. It is present in wash oil in concentrations clearly above 1 % triggering classification of wash oil as mutagenic Cat. 2 (CLP Regulation, Chapter 3.5, Table 3.5.2).
