Table 2 gives the results of the 1:1 mixture of reference item (nitric acid 65 %) with cellulose.

The mean time taken for the pressure to rise from 690 kPa to 2,070 kPa for the reference item (nitricacid 65 %) is2.40 s. The times taken for the pressure to rise from 690 kPa to 2,070 kPa for all 5 tests lie within the required range of ± 30 % of the arithmetic mean (1.68 s – 3.12 s).

In all five tests with the test item a pressure of 2,070 kPa was not reached within 60 s. Due to this result, the mean pressure rise time for the test item is greater than the mean pressure rise timefor the reference item (2.40s).

The test itemAmmonium2-ethylhexyl sulfatehas no oxidizing properties according to the UN Transport Regulation, division 5.1 andRegulation EC No. 440/2008 Method A.21. Oxidizing Properties of Liquids.

 

Interpretation of results:

GHS criteria not met

Conclusions:

Under the conditions of this test, the test item does not have to be classified as oxidizing substance in division 5.1 according to the UN Transport Regulation and the test item does not have to be classified as oxidizing liquid according to GHS or CLP Regulation EC 1272/2008 Annex 1.

Executive summary:

The oxidising properties of the test item were determined in a study according to UN Test O.2 and EU method A.21. The mean time taken for the pressure to rise from 690 kPa to 2,070 kPa for the reference item (nitric acid 65 %) is2.40 s. The times taken for the pressure to rise from 690 kPa to 2,070 kPa for all 5 tests lie within the required range of ± 30 % of the arithmetic mean (1.68 s – 3.12 s). In all five tests with the test item a pressure of 2,070 kPa was not reached within 60 s. Due to this result, the mean pressure rise time for the test item is greater than the mean pressure rise timefor the referenceitem (2.40s). The test itemAmmonium2-ethylhexyl sulfatehas no oxidizing properties according to the UN Transport Regulation, division 5.1 andRegulation EC No. 440/2008 Method A.21. Oxidizing Properties of Liquids.

Additional information

Oxidising liquids
The oxidising properties of the test item were determined in a study according to UN Test O.2 and EU method A.21. The mean time taken for the pressure to rise from 690 kPa to 2,070 kPa for the reference item (nitric acid 65 %) is2.40 s. The times taken for the pressure to rise from 690 kPa to 2,070 kPa for all 5 tests lie within the required range of ± 30 % of the arithmetic mean (1.68 s – 3.12 s). In all five tests with the test item a pressure of 2,070 kPa was not reached within 60 s. Due to this result, the mean pressure rise time for the test item is greater than the mean pressure rise timefor the referenceitem (2.40s). The test itemAmmonium2-ethylhexyl sulfatehas no oxidizing properties according to the UN Transport Regulation, division 5.1 andRegulation EC No. 440/2008 Method A.21. Oxidizing Properties of Liquids.

Oxidising solids
The substance is a a paste at 20 °C and 1013.25 hPa. Due to the consistency of the substance the test for oxidizing properties of solids (O.1) is not suitable and the test for oxidizing liquids (O.2) was performed.

Oxidising gases
The substance is a paste at 20 °C and 1013.25 hPa. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as oxidising gases.
  

Justification for classification or non-classification

 

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

Based on the chemical structure and taking into account the provisions laid down in Regulation (EC) No 1272/2008, as amended for the fifteenth time in Regulation (EU) 2020/1182, the substance is not considered to be classified for oxidising properties.
