no pyrophoricity
no flammability on contact with water

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Based on the test according to the EU Method A.10, the substance 6-methyl-2-oxoperhydropyrimidin-4yl urea (CAS 1129-42-6 is a non flammable solid. Basedon experience in handling and use and the chemical structure pyrophoricity and flammability on contact with water are not to be expected.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 or Directive 67/548/EEC and are therefore conclusive but not sufficient for classification:

Based on the test according to the EU Method A.10, the substance is a non flammable solid.

Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
