Remarks on result:

other: Burned vigorously

Preliminary test

The 2:1 w/w test mixture burned with a smoky, orange flame to completion in 184 seconds, with the 1:2 w/v test mixture taking 141 seconds. In contrast, the 3:2 w/w reference mixture burned vigorously to completion in 30 seconds. No further testing was considered necessary as both test mixtures burned significantly more slowly than the reference mixture, and examination of the structural formulae indicates that none of the components of test item would possess oxidising properties.

Interpretation of results:

other: no oxidising properties

Conclusions:

The test item is non-oxidising.

Executive summary:

Oxidising properties were determined in accordance with EEC Method A17.

The 2:1 w/w test mixture burned with a smoky, orange flame to completion in 184 seconds, with the 1:2 w/v test mixture taking 141 seconds. In contrast, the 3:2 w/w reference mixture burned vigorously to completion in 30 seconds. No further testing was considered necessary as both test mixtures burned significantly more slowly than the reference mixture, and examination of the structural formulae indicates that none of the components of test item would possess oxidising properties.

The test item is non-oxidising.

Description of key information

Oxidising properties were determined in accordance with EEC Method A17.

The test item burns significantly more slowly than a reference oxidiser when mixed with cellulose powder.

The test item is non-oxidising.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

The test item burns significantly more slowly than a reference oxidiser when mixed with cellulose powder. Thus the test item is non-oxidising determined by EEC Method A17 test.

The test item has an oxygen balance of considerably less than -200, and containing no chemical groups likely to contribute to oxidising properties.

In accordance with Regulation (EC) No. 1272/2008 section 2.14.2, the substance should not be classified as oxidising solid.
