Oxidising properties

Link to relevant study record(s)

Reference

Endpoint:

oxidising liquids

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test O.2 (Test for oxidizing liquids)

GLP compliance:

yes (incl. QA statement)

Other quality assurance:

other: SOP-LA-211

Remarks:

Oxidizing properties of liquids

Contact with:

powdered cellulose

Sample tested:

test mixture 1:1

Parameter:

mean pressure rise time

Remarks on result:

maximum pressure of 2070 kPa not reached

Sample tested:

reference mixture with 65% nitric acid + cellulose (1:1 ratio)

Parameter:

mean pressure rise time

Result:

2.58 s

Table 5 summarizes the results of the 1:1 mixture of test item with cellulose. The corresponding time pressure curves are shown in Figure 2.

	Test 1	Test 2	Test 3	Test 4	Test 5	Mean	Tolerance
Time [s] at 690 kPa	39.44	34.16	34.74	-	-	36.11	Minimum	Maximum
Time [s] at 2,070 kPa	-	-	-	-	-	-	-30%	+30%
Time for pressure rise [s]	-	-	-	-	-	-	-	-

Since the pressure of 690 kPa could not be reached in two of five tests, and also not the pressure of 2,070 kPa in five tests, no pressure rise time can be presented for the test item.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item has no oxidizing properties.

Executive summary:

The oxidizing properties of the test item Hydrogen [4-[[4-diethylamino)phenyl][4-[ethyl[(3-sulphonatobenzyl)amino]-o-tolyl]methylene]-3-methylcylohexa-2,5-dien-1-ylidene](ethyl)3-sulphonatobenzyl)ammonium, sodium salt was investigated according to UN Manual of Tests and Criteria O.2.

Since, the pressures of 690 kPa and 2,070 kPa  could not be reached, the pressure rise time for the test item is greater than the mean pressure rise time for the reference item nitric acid 65 % (2.58 s).

According to the results of the test on oxidizing properties of liquids, the test item is classified as follows:

UN Transport Regulation: The test item does not have to be classified as oxidizing substance in division 5.1 according to the UN Transport Regulation.

GHS (CLP Regulation EC 1272/2008: Annex 1: 2.13): The test item does not have to be classified as oxidizing liquid according to GHS or CLP Regulation EC 1272/2008 Annex 1.

Description of key information

The oxidizing properties of the test item Hydrogen [4-[[4-diethylamino)phenyl][4-[ethyl[(3-sulphonatobenzyl)amino]-o-tolyl]methylene]-3-methylcylohexa-2,5-dien-1-ylidene](ethyl)3-sulphonatobenzyl)ammonium, sodium salt was investigated according to UN Manual of Tests and Criteria O.2. Since, the pressures of 690 kPa and 2,070 kPa  could not be reached, the pressure rise time for the test item is greater than the mean pressure rise time for the reference item nitric acid 65 % (2.58 s).

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification
