Reference
Endpoint:
relative self-ignition temperature (solids)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP compliant guideline study, available as unpublished report. No restrictions, fully adequate for assessment
Justification for type of information:
A discussion and report on the read across strategy is given as an attachment in IUCLID Section 13.
Reason / purpose:
read-across: supporting information
Qualifier:
according to
Guideline:
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Deviations:
yes
Remarks:
Mesh size of wire used for the cube was 0.042mm not 0.045mm as specified in the guideline
GLP compliance:
yes (incl. certificate)
Key result
Relative self-ignition temperature:
> 400 °C
Remarks on result:
other: Pressure not stated, therefore assumed standard
Remarks:
at atm. press. of 101.3 kPa

Whilst heating the test item, no relevant exothermic reaction or self-heating of the sample was observed.An expanded black charred solid remained.

Conclusions:
The test item was determined not to have a relative self-ignition temperature below 400°C.
Executive summary:

The test item was heated in a fine mesh stainless steel cube suspended in an oven. Temperature/time curves did not reveal any relevant exothermic or self-heating of the sample. The test item was therefore determined not to have a relative self-ignition temperature below 400°C.

Description of key information

There is no data available for Resin acids and rosin acids, reaction products with formaldehyde, sodium salts. However, data available from a structural analogue Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is used as read across.

Self-ignition temperature was measured for six substances in the category Rosin, hydrogenated rosin and their salts. The results range from 335.5 °C to >400°C.

The self-ignition temperature for Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is >400°C.

Key value for chemical safety assessment

Additional information

There is no data available for Resin acids and rosin acids, reaction products with formaldehyde, sodium salts. However, data available from a structural analogue Resin acids and rosin acids, reaction products with formaldehyde, potassium salts is used as read across.

A GLP-compliant study, conducted according to EU Method A.16 (Relative Self-Ignition Temperature for Solids), was provided for Resin acids and Rosin acids, reaction products with formaldehyde, potassium salt (Harlan Laboratories Ltd., 2012c).
