Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline compliant study with good documentation.
Qualifier:
according to guideline
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
GLP compliance:
no
Relative self-ignition temperature:
> 400 °C
Remarks on result:
other: Air pressure not provided, however, normal atmospheric pressure can be assumed for this laboratory.

The test item doesn’t reach 400 °C during the self ignition.

Therefore the test item has no relative self ignition temperature according to the definition in the Council Regulation (EC) 440/2008, method A.16.

Executive summary:

In the non-GLP Klimisch1 study from Bütfering (2012) the self ignition temperature of Aspartic acid, N-(3-carboxy-1-oxo-sulfopropyl)-N-(C16-18 (even numbered), C18 unsaturated alkyl) tetrasodium salts was determined according to EU method A.16. The test item had no self ignition temperature above 400°C. Therefore the test item has no Relative Self-Ignition Temperature according to the definition in the Council Regulation (EC) No 440/2008, method A. 16.

This information is considered to be relevant and reliable for the further risk assessment.
