Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Key value for chemical safety assessment

Additional information

According to REACH Regulation (Annex XI, 1.), a study does not need to be done if based on the available data the substance can be classified, labelled and/or the risk of the substance can be assessed. Alpha-methylstyrene is a liquid at room temperature. For liquids the primary value for ease of ignition is the flash point. Moreover, the experience in the use and testing for other REACH endpoints showed that the substance does not ignite spontaneously in air or react violently with water and therefore testing according to EC Methods A.12 and A.13 is therefore not scientifically necessary. Flammability limits in air have been reported in reliable, peer-reviewed sources

Justification for classification or non-classification
