- Remarks on result:
- other: Mean time to reach 2,070 kPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Whilst a pressure rise above 690 kPa did occur when the test item was subject to experimental conditions, this pressure rise did not exceed 2,070 kPa and took longer to occur than the reference item. Further the test item did not spontaneously ignite when mixed with cellulose.
- Executive summary:
Following a series of five tests, a mean pressure rise was determined for Amines, C12-C14-branched alkyl, dodecylbenzenesulfonates(1:1) under experimental conditions. The mean pressure rise achieved by the test item in a 1:1 mixture, by mass, with cellulose was between 690 kPa and 2070 kPa and occured over a time period of > 60 sec.
A reference item of nitric acid 65 % in a 1:1 mixture, by mass, with cellulose achieved a pressure rise that exceeded 2,070 kPa in a mean time 20.73 following five tests.

Description of key information
Oxidising Properties: Not oxidising; EU Method A.21.; S Seitz (2017)
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
EU Method A.21. – The oxidising properties of the test item were determined using a procedure designed to be compatible with Method A.21. Oxidising Properties (Liquids) of Commission Regulation (EC) No 440/2008 of 30 May 2008.
An aliquot (approx. 2.5 g) of test item was carefully mixed with about 2.5 g of dried cellulose and observed for ignition. In the absence of ignition this mixture was then added in small portions to the test apparatus (as described in the technical guideline). The apparatus was sealed in the required manner and the test mixture heated until the rupture disk ruptures or until at least 60 s have elapsed. Five trials were performed with both the test item and a reference item (1:1 mixture, by mass, of 65 % aqueous nitric acid and cellulose). The time taken for the pressure to rise from 690 kPa to 2,070 kPa above atmospheric was noted. The mean pressure rise times for both the test item and the reference item were calculated. No single result from this trials series should differ by more than 30 % from the arithmetic mean.
In all (five) test item trials the pressure exceeded 690 kPa but failed to reach 2,070 kPa. Meaning the pressure to rise from 690 kPa to 2,070 kPa for the test item is greater 60 s. All 5 tests were within the required range of ± 30 % of the arithmetic mean. The reference item achieved a pressure to rise from 690 kPa to 2,070 kPa in a mean time of 2.98 s.
The test item cannot be categorised in accordance with Commission Regulation (EC) No 1272/2008 (Classification Labelling and Packaging) of 16 December 2008.
Justification for classification or non-classification
The test item is not classified as an oxidising liquid in accordance with the classification criteria defined in Section 2.13.2.1., Annex II of Regulation (EC) 1272/2008 of December 2008. The test item does not spontaneously ignite when in a 1:1 mixture by mass with cellulose, nor does such a mixture achieve a comparable rise in pressure when heated under confinement in comparison to a prescribed reference substance.
