Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
substances / mixtures which in contact with water emit flammable gases
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
Endpoint:
flammable solids
Data waiving:

Justification for data waiving:

Endpoint:
pyrophoric solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied

Description of key information

Testing of flammability does not appear scientifically necessary according to Regulation (EC) No 1907/2006, Annex XI, Section 1.

-Testing of flammability of solids (A.10) and gases (A.11) is not considered to be required, since the cations contained in the pigment are in the highest possible oxidation state, and the pigment is therefore incapable of further reaction with oxygen.

- Testing for flammability in contact with water (A.12) is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable.

- Testing of pyrophoric properties of solids and liquids (A.13) is not considered to be required, since the substance is stable at ambient temperature. It does not contain any chemical group that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (approx. 20 °C).

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammability:

In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, the study does not need to be conducted. Considering that this pigment was produced by high temperature calcination, testing of flammability is not considered to be required. Cations contained in the pigment are in the highest possible oxidation state, and the pigment is therefore incapable of further reaction with oxygen. This substance can thus be designated as non-flammable (Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance, section R.7.1.10.3). Furthermore, long-term industrial experience in handling shows that the substance is not flammable.

Phyrophoric properties:

In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied. Furthermore, long-term industrial experience in handling shows that the substance does not ignite spontaneously in contact with air

Flammability in contact with water:

Testing for flammability in contact with water is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases (in accordance with Regulation (EC) 1907/2006, Annex XI, Section 1).

Justification for classification or non-classification

The pigment does not need to be classified according to CLP Regulation (EC) No 1272/2008 since it is not highly flammable.
