Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
Endpoint:
flammable solids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a liquid

Key value for chemical safety assessment

Flammability:
not classified

Additional information

According to REACH guidance R7a, the flammability of liquids is determined on basis of their flashpoint (in combination with their boiling point), their ability to emit flammable gases upon contact with water and their pyrophoricity. The minimum flash point being higher than 60°C (see section 4.11), this substance is considered as non-flammable (CLP Regulation CE 1272/2008).

 

The molecular structure of the constituents does not contain groups that indicate potential reactivity with water or pyrophoric properties and the experience in handling and use of this substance indicates that this is the case.

Justification for classification or non-classification

The minimum flash point is >60°C (see section 4.11).
