Specific details on test material used for the study:

Identity: FAT 40825/A
Batch number: CHU 297 / BOP 04/05
Purity: Organic part (Na-salt): approx. 83.7 %; All coloured components: approx. 80.54 %; Main component: approx. 59.1 %.
Appearance: Solid, black powder
Storage conditions: At room temperature at about 20 °C
Expiration date: December 31, 2010

Contact with:

powdered cellulose

Sample tested:

test mixture as specified

Remarks:

Test item : Cellulose ratio of 2:1

Parameter:

preliminary test

Remarks on result:

other: e FAT 40825/A/cellulose mixture ignited poorly and the flame became orange. Without contact to the ignition source, the flame extinguished after 2 seconds. White smoke was observed and the test item mixture glowed for about 2.5 minutes.

Sample tested:

reference mixture as specified

Remarks:

Barium nitrate : cellulose ratio = 2:1

Parameter:

preliminary test

Remarks on result:

other: The barium nitrate/cellulose mixture during the same test burned for 80 seconds with a blazing, light yellowish flame, emitting sparks.

During the preliminary test the FAT 40825/A/cellulose mixture ignited poorly and the flame became orange. Without contact to the ignition source, the flame extinguished after 2 seconds. White smoke was observed, and the test item mixture glowed for about 2.5 minutes. The barium nitrate/cellulose mixture during the same test burned for 80 seconds with a blazing, light yellowish flame, emitting sparks. Since the test item mixture burned clearly slower than the barium nitrate mixture, a main test was not necessary.

Interpretation of results:

GHS criteria not met

Conclusions:

FAT 40825/A has no oxidizing properties.

Executive summary:

The determination of the oxidizing properties of FAT 40825/A was performed in accordance with the EEC Directive 92/69, Methods for the determination of physico-chemical properties, A. 17 "Oxidizing Properties (solids)", EEC Publication No. L383, December 1992. During the preliminary test the FAT 40825/A/cellulose mixture ignited poorly and the flame became orange. Without contact to the ignition source, the flame extinguished after 2 seconds. White smoke was observed and the test item mixture glowed for about 2.5 minutes. The barium nitrate/cellulose mixture during the same test burned for 80 seconds with a blazing, light yellowish flame, emitting sparks. Since the test item mixture burned clearly slower than the barium nitrate mixture, a main test was not necessary. In conclusion, FAT 40825/A has no oxidizing properties.

Justification for classification or non-classification

In a test according to EU method A.17 the substance showed to be not an oxidiser. Consequently, the substance is not classifiable for oxidising properties according to CLP (Regulation EC No 1272/2008)
