Description of key information

A study is scientifically unjustified, since methylcyclohexane has a flash point below 23 °C and a initial boiling point higher than 35 °C and therefore meets the criteria of Category 2 for flammability.

Key value for chemical safety assessment

Flammability:
highly flammable

Additional information

In accordance with Regulation (EC) No 1907/2006, Annex XI this study is scientifically unjustified. The flammability of liquids is determined on the basis of their flashpoint (in combination with their boiling point), their ability to emit flammable gases upon contact with water and their pyrophoricity. The molecular structure of methylcyclohexane does not contain groups that indicate potential reactivity with water or pyrophoric properties and handling of methylcyclohexane indicates that this is the case. The flashpoint indicates that methylcyclohexane is a Category 2 -Highly flammable liquid. Methylcyclohexane was placed in this hazard class because it has a flash point below 23 °C and a initial boiling point higher than 35 °C and therefore meets the criteria of Category 2 for flammability.
