Results and discussion

Relative self-ignition temperature (solids)
Relative self-ignition temperature:
220 °C
Remarks on result:
other: result refers to the measurement of the pure substance and the 1:1 Kieselgur mixture

Any other information on results incl. tables

A multi-step reaction starting at 220°C was noted with the pure product, but substiantial temperature increase (> 500°C) was recorded above 300°C.

The Kieselguhr mixture exhibited a temperature increase up to > 650°C starting at 220°C.

Applicant's summary and conclusion

Conclusions:
Due to the results from the Grewer-Oven screening test the test item has not to be classified as self-heating substance according to Regulation (EC) No 1272/2008.
