- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1 Oct 2020
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- GLP compliance:
- yes
- Type of method:
- differential scanning calorimetry

- SOURCE OF TEST MATERIAL
- Source (i.e. manufacturer or supplier) and lot/batch number of test material: Super Ester A-75 / Lot
K9C029
- Purity:100% (w/w)
- Expiration date: 14 July 2025 - Key result
- Decomposition:
- yes
- Decomp. temp.:
- 194 °C
- Remarks on result:
- other: Pressure build-up required for decomposition
- Conclusions:
- The decomposition point of rosin acid derivative was determined to be 194 °C (OECD 103).
- Executive summary:
The decomposition temperature of rosin acid derivative was determined using differential scanning calorimetry (DSC). The study showed decomposition required pressure build-up and post-analysis observations of the sample revealed little to no visible material remaining in the pans. The study was conducted in accordance with OECD 103 guideline and was GLP compliant. Therefore the study is considered reliable without restrictions.

- yes

- ca. 228 °C
- Remarks on result:
- other: Boiling point not determined
- Conclusions:
- Test was terminated at 228°C and no boiling point was observed under the test conditions.
At this temperature discoloration of the test sample was observed. This phenomenon is not the consequence of mass decomposition of the substance but occurs when the resin is not correctly stored and when heating the substance in a non-inert atmosphere (due to the formation of some chromophores).
Any heating to elevated temperatures should occur under inert gas conditions to prevent darkening of the product. - Executive summary:

No peaks corresponding to melting or decomposition were found for samples heated in containers with holes in their lids (Fig 3). Decomposition was only observed using no-pinhole lids, indicating that pressure build-up is required. Thus, atmospheric pressure was not recorded. Post-analysis observations of the sample revealed little to no visible material remaining in the pans. Any small amounts of remaining material resembled the original material.
Apparatus : Boiling temperature device with liquid bath and thermometer.

Result : Not determined
The sample began to discolour at 228°C, this was suspected to be decomposition of the sample and therefore the test was terminated.
Description of key information
No boiling point was observed for most of the substances in the category Rosin esters up to the temperatures reported (up to 300°C). No decomposition was observed up to 300°C . Boiling points for those substances in the category where boiling was determined range from 360 – 450°C.
The decomposition point of rosin acid derivative was determined to be 194 °C (OECD 103) under pressure build-up.
Key value for chemical safety assessment
Additional information
The study was conducted in accordance with OECD 103 guideline and was GLP compliant. The decomposition temperature of rosin acid derivative was determined using differential scanning calorimetry (DSC). The study showed decomposition required pressure build-up and post-analysis observations of the sample revealed little to no visible material remaining in the pans. The study is considered reliable without restrictions.
A GLP-compliant study, conducted according to EU Method A2 Siwoloboff, was provided for Resin acids and rosin acids, esters with glycerol (Chilworth Technology, 2010 a). Resin acids and rosin acids esters with glycerol was heated in capillary tube. Test was terminated at 228°C and no boiling point was observed under the test conditions. The test material in this study may be thought of as forming a part of the registered substance composition. Information provided to support readacross.
