EC number: 202-705-0
CAS number: 98-83-9
not required (flammability limits in air: 0.7-6.1%)
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
