Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The substance is a liquid. Therefore the flammability of liquids was classified on basis of the flashpoint of 212.5 °C (Chapter 4.11).
In accordance with section 1 of REACH Annex XI, the study on flammability in contact with water does not need to be conducted as the substance contains no metals or metalloids and there-fore will not release flammable gases in contact with water.
In accordance with section 1 of REACH Annex XI, a study does not need to be conducted as it is scientifically unjustified. Based on experience during handling and use, no pyrophoric properties were observed and the structure does not give a reference to pyrophoric properties.
This classification is supported by the classification of 2,4-MDI (CAS 5873-54-1) which is the main component of the substance with the lowest molecular weight and the highest vapour pressure. For this reason it represents the worst case
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
Justification for classification or non-classification
2,4'-MDI (CAS 5873-54-1), which is the main component with the lowest molecular weight and the highest vapour pressure, was found to be not highly flammable, not pyrophoric, and to have non-hazardous flammability in contact with water. The “read across” classification is justified as the result represents the worst case.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
