flammable liquids: obsolete as covered by section 'Flash point'
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid

Description of key information

The flammability of liquids is determined on basis of their flash point (in combination with their boiling point), the ability to emit flammable gases upon contact with water and their pyrophoricity. The substance has a high flashpoint (111°C) and a boiling point of 246.8°C not indicating flammability. With regards to flammability in contact with water, the structural features of the substance were evaluated and it was concluded that the substance does not contain groups that might lead to the evolution of a dangerous amount of flammable gas when coming into contact with water or damp air (ECHA guidance R.7.1.10.8, 2017). No metals, transition metals, boron or silicon are present. Also, handling during the water solubility test confirms this conclusion. With regards to pyrophoric properties, evaluation of the structural features of the substance revealed that the substance does not contain any chemical group that might lead to spontaneous ignition a short time after coming into contact with air (ECHA guidance R.7.1.10.5, 2017).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Justification for classification or non-classification

Based on the flashpoint of Cyclacet (111°C), the substance is considered non-flammable in accordance with EU CLP (EC No. 1272/2008 and its amendments).
