SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: SOAP012-2
- Expiration date of the lot/batch: 01 November 2022


STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Ambient
Remarks on result:
no self ignition observed under the test conditions

During the first exothermic event (onset temperature 167.4C) the sample began to melt. After the first exothermic event, a second was observed (onset temperature 202.6 C). The sample is suspected of decomposing whilst liquidising. However, both exothermic event peak temperatures were <400 C. Therefore it was concluded that the sample is not a self-igniting solid.

Conclusions:
Under the conditions of the test, fatty acids, lanolin, lithium salts, is not a self-igniting solid.
Executive summary:

The self-ignition of the test item was determined in a study according to EC Method A.16 (Dunning 2018). During the first exothermic event (onset temperature 167.4C) the sample began to melt. After the first exothermic event, a second was observed (onset temperature 202.6 C). The sample is suspected of decomposing whilst liquidising. However, both exothermic event peak temperatures were <400 C. Therefore it was concluded that the sample is not a self-igniting solid.

The study is GLP-compliant and was conducted according to the standard guideline, therefore is considered reliable without restrictions and suitable as a key study for this endpoint.

Description of key information
