Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Pyrophoric solids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.
Pyrophoric liquids
Test procedure:
ignition time on contact with air
Remarks:
Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
Remarks on result:
no ignition on contact with air (not further specified)
Remarks:
corresponding to 'no' in migrated source record.

Any other information on results incl. tables

The test substance has a "Brennzahl" of 2: "catches fire briefly and extinguishes rapidly"(definition according to HVBG, 2001).

The study report gives a very similar definition ofcombustion class 2 as¿brief ignition and rapid extinction¿.

The same results are found when 20%, 40% or 60% of diatomaceous earth (¿Kieselguhr¿) are added to the pigment sample.

As the flames do not propagate no burning rate can be determined.
