The results of the QSAR predictions (Howard
et al. 1992, 2005) for the butenes category (but-1-ene (CAS 106-98-9), 2
-butene (CAS 107-01-7) and 2-methylpropene (CAS 115-11-7)) indicate that
they are expected to degrade rapidly, with an estimated half life of 2
days to 2.8 days. These results indicate that they would not meet the
criteria for persistent in the PBT assessment and do not indicate the
potential for long term effects in the environment for the
classification and labelling assessment.
