Qualifier:

according to guideline

Guideline:

UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)

Deviations:

no

GLP compliance:

no

Test procedure:

100 mm sample cube at 140°C

Max. temp. reached:

215

Induction time (h):

24

Result:

positive outcome (effect observed)

Test procedure:

25 mm sample cube at 140°C

Max. temp. reached:

277

Induction time (h):

24

Result:

positive outcome (effect observed)

The 100 mm³ sample container and 25 mm³ container were filled to the brim with the sample. Thermocouples were inserted into the center of the test sample. In both trials, the temperature of the sample exceeded that of the oven by greater than 60°C.

Substance	Cube size [mm]	Oven Temp. [°C]	Result
Sodium mentholate	100	140	Sample temperature exceeded the oven temperature by greater than 60°C during the 24 testing period. Max temperature was 215 °C.
Sodium mentholate	25	140	Sample temperature exceeded the oven temperature by greater than 60°C during the 24 testing period. Max temperature was 277 °C.

Based on the test results for both trials, the sample gave a positive result during the UN Test N.4, “Test method for self-heating substances”, is considered a self-heating substance, and is classified in Division 4.2, Packing Group II.

Interpretation of results:

other: Category 1 (self-heating substances and mixtures) based on EU GHS criteria

Conclusions:

The sample gave a positive result in the 100 mm and 25 mm cube at a test temperature of 140 °C.

Executive summary:

The sample was tested for its self-heating properties according to UN Test N.4 in a non-GLP study. The sample gave a positive result in the 100 mm and 25 mm cube at a test temperature of 140 °C. Therefore the substance has to be classified as self-heating substance Category 1 according to EU GHS criteria.
