Preliminary Test

The mixture of the test substance with cellulose was ignited by touching with the flame, but the reaction was not vigorous. The yellowish smoke released. Because of no violent reaction, it was not possible to consider the test substance as an oxidant and the train test was performed according to a defined procedure.

Test

The test substance cellulose mixture having the fastest burning rate was retested in an inert atmosphere (under nitrogen) for exclusion of false positive result.

It was evident that mixture of test substance with fastest burning rate didn’t burn in the nitrogen atmosphere. The test substance should not be considered as oxidizing despite higher burning rate of test substance mixture with cellulose (60:40, w/w) than reference mixture (60:40, w/w) measured in normal laboratory conditions.

Interpretation of results:

GHS criteria not met

Conclusions:

Based on results obtained from trial test, it is obvious that none of the test substance mixtures with cellulose did not burn in inert atmosphere. Thus test substance, Pigment Yellow 4, should not be considered as a substance with oxidizing properties.

Executive summary:

The oxidizing properties of test substance, Pigment Yellow 4, were determined. The procedure was performed according to the Method A.17 Oxidizing properties (Solids), Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008. Based on results obtained from trial test, it is obvious that test substance mixture with cellulose did not burn in inert atmosphere. Thus test substance, Pigment Yellow 4, should not be considered as a substance with oxidizing properties.

Description of key information

The procedure was performed according to the Method A.17 Oxidizing properties (Solids), Council Regulation (EC) No.440/2008, published in O.J. L 142, 2008. Based on results obtained from trial test, it is obvious that none of the test substance mixtures with cellulosedid not burn in inert atmosphere. Thus test substance, Pigment Yellow 4, should not be considered as a substance with oxidizing properties.
