Description of key information

EC Physico/Chemical Test A17, Oxidizing Properties (Solid) Test: not oxidising

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

The oxidising properties of C.I. Pigment Red 104 were determined in accordance with the EC Physico/Chemical Test A17, Oxidizing Properties (Solid) Test. In the preliminary test, the burning time of C.I. Pigment Red 104 was determined to be more than the reference sample in the preliminary screening test. Therefore the full train test was conducted.

In the full train test, the highest burning rate recorded from the six samples of C.I. Pigment Red 104 in cellulose was 0.36 mm/s, which was the sample with 80% of the test substance. This value should be compared to the highest burning rate of the reference substance Barium Nitrate, which was 0.85mm/s. It can be concluded that the sample of C.I. Pigment Red 104 should not be classed as an oxidizing substance since in any percentage of C.I. Pigment Red 104/Cellulose, it has a burning rate of less than that of Barium Nitrate/Cellulose per EC Physico/Chemical Test A17, Oxidizing Properties (Solid) Test.

Justification for classification or non-classification

Based on the available information, C.I. Pigment Red 104 does not have to be classified as oxidising, in accordance with the criteria outlined in Annex VI of 67/548/EEC and Annex I of 1272/2008/EC.
