Resin acids and Rosin acids, reaction products with formaldehyde, sodium salts

Auto flammability

Link to relevant study record(s)

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other: GLP compliant guideline study, available as unpublished report.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 for cross-reference:

read-across: supporting information

Qualifier:

according to guideline

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. QA statement)

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.

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).
