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

Interpretation of results:

GHS criteria not met

Remarks:

acc. to CLP Regulation

Conclusions:

Phytosphingosine could not be ignited with a flame, although it emitted yellow sparks and melted in contact with the ignition source. After removal of the ignition source, no more sparks were observed. The molten test substance turned brown. In conclusion, Phytosphingosine is not "highly flammable" according to the criteria of the directive.

Executive summary:

The determination of the flammability of Phytosphingosine was performed in accordance with EEC-Directive 92/69 EEC, A.10 "Flammability (solids)" (1992).

Phytosphingosine was formed in a wedge-shaped pile with a length of 25 cm, a width of 2 cm and 1 cm in height. An attempt was made to ignite the test substance with the flame of a gas-burner. The test

substance could not be ignited with a flame, although it emitted yellow sparks and melted in contact with the ignition source. After removal of the ignition source, no more sparks were observed. The molten test substance turned brown. In conclusion, Phytosphingosine is not "highly flammable" according to the criteria of the directive.

Description of key information

Phytosphingosine could not be ignited with a flame, although it emitted yellow sparks and melted in contact with the ignition source. After removal of the ignition source, no more sparks were observed. The molten test substance turned brown. In conclusion, Phytosphingosine is not "highly flammable" according to the criteria of the test guideline.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

The submission substance does not need to be classified as flammable solid, because the submission substance does meet the classification criteria set out in the CLP Regulation; i.e. Phytosphingosine 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.
