Key result
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

Potassium 12-hydroxystearate melted but did not ignite during the 2 minutes of application of the burner flame. The flame did not propagate along the train. No further testing was necessary.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
Potassium 12-hydroxystearate is determined to be not highly flammable as the substance did not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minute test period.
Executive summary:

The flammability of potassium 12-hydroxystearate was determined in a GLP-compliant study following EC method A.10. Potassium 12-hydroxystearate melted but did not ignite during the 2 minutes of application of the burner flame. The flame did not propagate along the train. The test item was found to be not highly flammable. No further testing was necessary.

Description of key information

Potassium 12-hydroxystearate is determined to be not highly flammable as the substance did not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minute test period.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

The flammability of potassium 12-hydroxystearate was determined in a GLP-compliant study following EC method A.10 (Agrochemex 2018). Potassium 12-hydroxystearate melted but did not ignite during the 2 minutes of application of the burner flame. The flame did not propagate along the train.The test item was found to be not highly flammable. No further testing was necessary.

Justification for classification or non-classification

Potassium 12-hydroxystearate is determined to be not highly flammable and to not meet the critera for classification for flammability as the substance did not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minute test period.
