Description of key information

According to REACH Annex XI, 1 a study on flammability is scientifically unjustified, as the classification and labelling criteria for flammability of a liquid is determined by the flash point (Guidance on information requirements and chemical safety assessment. Chapter 7a: Endpoint specific guidance, 7.1.10). The substance is not pyrophoric and is not flammable in contact with water.

Key value for chemical safety assessment
