Type of information:

experimental study

Adequacy of study:

key study

Study period:

2012

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Guideline compliant study with good documentation.

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

GLP compliance:

no

Key result

Relative self-ignition temperature:

259 °C

Remarks on result:

other: Air pressure not provided, however, normal atmospheric pressure can be assumed for this laboratory.

The test item reached 400°C during the self ignition. Self ignition started at 259°C.

Executive summary:

In the non-GLP Klimisch1 study from Bütfering (2012) the self ignition temperature of Sulfosuccinic (FA C12-18)E, 2Na was determined according to EU method A.16. The test item reaches a self ignition temperature above 400°C. Self ignition started at 259°C. Therefore the test item has a 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.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
