Additional information

According to Annex VII of the REACH Regulation 1907/2006, Column 2, the study does not need to be conducted if the melting point is above 300 °C. If the melting point is between 200 °C and 300 °C, a limit value based on measurement or a recognised calculation method is sufficient.

Decomposition of the test item beginning at 273 °C.

The lowest value accepted by EUSES has been reported for a complete Risk assessment. The lowest value accepted by EUSES has been reported for a complete Risk assessment (0.0000001 Pa).

Other estimated values are lower than the EUSES value:

VP(mm Hg,25 deg C): 3.28E-033 (Modified Grain method)

VP (Pa, 25 deg C) : 4.37E-031 (Modified Grain method)
