Remarks on result:
other: No exothermic effect of the test substance was observed. It demonstrated that the test substance is “not a self-heating substance

Results

 

No exothermic effect of the test substance was observed. It demonstrated that the test substance is “not a self-heating substance”. According to the guideline, no further testing was required.

 

After the experiment, the test substance had turned into a brown/black residue. It indicated that the test substance had been molten, decomposed and/or reacted during the experiment.

Conclusions:
The self-heating temperature of Vinasses was determined by Test 1 of the Modified Bowes-Cameron Cage test.

Based on the results obtained, the test substance is considered “not a self-heating substance”.

Description of key information

Auto-ignition temperature: not applicable.
Not a self-heating substance.

Key value for chemical safety assessment

Additional information

For dry matter of Vinasses auto flammability was derived from a test with Vinasses, residue of fermentation containing biomass of Corynebacterium glutamicum, which was performed according to UN RTDG Test N.4. Since all Vinasses subgroups are very similar in composition, auto flammability is as well very similar.

Vinasses in form of suspension and paste are composed of dry matter of Vinasses and water, thus, a self-heating property is not expected.
