Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Sponsor / 181101001
- Expiration date of the lot/batch: 31. Oct. 2020
- Purity test date: 01 Nov 2018

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: The test item was stored in the test facility in a tightly closed vessel at room temperature (20 ± 5 °C ) away from humidity.
- Stability under test conditions: Stable
- Solubility and stability of the test substance in the solvent/vehicle:
Stability in solvents: H2O: 96h; EtOH: unknown; acetone: unknown; CH3CN: unknown; DMSO: unknown
Solubility in solvents: H2O: > 1 g/L; EtOH: unknown; acetone: unknown; CH3CN: unknown; DMSO: unknown

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

      

Safety pre-test

The flame became orange – purple and the test item melted. The liquid burned with an orange – purple, sooting flame.

   

Preliminary screening test

In the preliminary screening test following the EU and the UN method, the test item was heated with the flame of a teclu burner. The flame became purple and the test item compressed. No ignition occurred within two minutes.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

No ignition was observed throughout the course of the test.
The test item Potassium isobutyrate should be considered as not highly flammable (for EU regulations) and as non-flammable solid (for UN regulations).
No observations were made which might cause doubts concerning the validity of the study outcome.

Description of key information

One key study was performed in accordance with EU Method A.10 and under the condition of GLP.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

No ignition was observed throughout the course of the test.

The test item Potassium isobutyrate should be considered as not highly flammable (for EU regulations) and as non-flammable solid (for UN regulations).
