STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: Approximately -20°C, under nitrogen, in the dark - Key result
- Melting / freezing pt.:
- >= 24.2 - <= 51.2 °C
- Remarks on result:
- other: ± 0.5°C
- Conclusions:
- The melting range of the test substance was determined to be 24.2 - 51.2 ± 0.5°C (297 to 324 ± 0.5°K).
- Executive summary:
The melting range of the test substance, Resin acids and Rosin acids, esters with trimethylolpropane, was determined via differential scanning calorimetry using a procedure compatible with Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No. 440/2008 of 30 May 2008, Method 102 of OECD Guidelines for Testing of Chemicals, 27 July 1995 and Method 830.7200 of the OPPTS Guidelines, March 1998.
The temperature accuracy of the DSC instrument was checked prior to testing with indium and zinc and was within defined tolerances and therefore the instrument was considered acceptable for use. Aliquots of the test substance were placed in twiced pierced cruicbles and subjected to a thermal programme from 0 -100°C at 5°C/min. It is considered that the test substance had fully mobilised as the residue was around the periphery of the crucible.
Since the test substance is a complex mixture (UVCB), a melting range has been reported. The melting range for the test substance was determined to be 24.2 to 51.2 ± 0.5°C (297 to 324 ± 0.5 K).
Reference
The residue was a transparent solid around the periphery of the crucible.
One broad endotherm was observed up to 100°C, with no apparent glass transition observed in the thermogram.
Description of key information
The melting range of Resin acids and Rosin acids, esters with trimethylolpropane was determined via differential scanning calorimetry using a procedure compatible with Method A.1 Melting / Freezing Temperature of Commission Regulation (EC) No. 440/2008 of 30 May 2008; Method 102 of OECD Guidelines for Testing of Chemicals, 27 July 1995; and Method 830.7200 of the OPPTS Guidelines, March 1998.
Since the test substance is a complex mixture (UVCB), a melting range has been reported. The melting range for the test substance was determined to be 24.2 to 51.2 ± 0.5°C (297 to 324 ± 0.5 K).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 37.7 °C
Additional information
The melting range for the test substance was determined to be 24.2 to 51.2 ± 0.5°C (297 to 324 ± 0.5 K). The key value for chemical safety assessment is the average between the the lowest and highest measured value: 37.7 ± 0.5°C.
