Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Half-life for reaction with photochemically-produced hydroxyl radicals: estimated 11.8 hours.

Overall degradation rate constant with OH radicals= 2.83E-6 cm3/(molecule-day).

Key value for chemical safety assessment

Half-life in air:
11.8 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

The stability of the test material in the atmosphere was calculated using the software AOPWIN (v1.92).

It is predicted that the test material will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals, with a half-life of 11.8 hours, at European test conditions.

The overall degradation rate constant with OH radicals was estimated to be 3.28E-11 cm3/molecule-sec, equivalent to 2.83E-6 cm3/molecule-day.
