Applicant's summary and conclusion

Conclusions:

The test material was determined to have an auto-ignition temperature above 400°C.

Executive summary:

A study was conducted to determine the auto-ignition temperature of synthetic inositol phosphates according to EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases)).

Aliquots of test material were injected in a heated flask using a syringe and were observed for signs of ignition for 300 seconds.

The test material has been determined to have an auto-ignition temperature above 400°C.
