Key value for chemical safety assessment

Flammability:

non flammable

Additional information

The test item could not ignited in an EU A10 flammability study. Therefore, the substance is considered not to be highly flammable.

A test substance is considered pyrophoric when it ignites within five minutes of coming in contact with air. The test substance does not contain groups that might lead to ignition in contact with air. Moreover the test substance was handled under normal laboratory conditions during this project. It demonstrated that the test substance does not ignite in contact with air. In conclusion, In conclusion, CUCURBIT[8]URIL is considered ‘not highly flammable’ has no pyrophoric properties.

A test substance is considered highly flammable when it ignites spontaneously in contact with water, or evolves a flammable gas at a minimum rate of ≥ 1 litre/kg of the substance per hour.

 

The test substance does not contain groups that might lead to ignition in contact with water and/or to the evolution of a flammable gas. Moreover the test substance was dissolved in water during the determination of the water solubility (see section 4.8). It demonstrated that the test substance does not ignite spontaneously in contact with water. In conclusion, CUCURBIT[8]URIL is considered ‘not highly flammable’ in contact with water.

Justification for classification or non-classification

The above results triggered no classification under the CLP Regulation (EC No 1272/2008).
