Amidoamine (UVCB)
Pulcra ID: DE07_2014_012_BEL66 (amidoamine without emulsifier)
Physical state: pale yellowish solid at 20 °C
Batch No.: K8 4309 L481
Expiry date of batch: 09 March 2018
Purity: 100 % (UVCB)
Stability: stable under test conditions
Storage condition of test material: Room temperature, protected from light - Key result
- Melting / freezing pt.:
- 98.7 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 213 °C
- Conclusions:
- The melting temperature of the test item was determined to be 98.7 ± 0.5 °C (372 ± 0.5 K).
- Executive summary:
In the Klimisch 1 GLP study the melting point of amidoamine test item was determined with the DSC method according to OECD 102 and EU method A.1. The test item did not show melting up to 98 °C. From 213 °C the test item shows most probably a thermal decomposition with change in color. This study is considered relevant for the risk assessment.
Reference
Aliquots of test item were placed in aluminum crucibles and were subjected to a thermal program as shown in the following table. The appearance of the samples (residue) was recorded after the test.
The thermograms showed a broad endotherm consistent with softening and melting of a waxy substance. The extrapolated onset of the endotherm peak was reported as the melting temperature. Additional testing was performed to obtain a definitive melting temperature using a temperature gradient of 1 °C/minute up to 120 °C.
However, since these thermograms demonstrated a low response over the melting range, it was considered acceptable to report the extrapolated onset of determinations 1 and 2 as the melting temperature (see table 2).

Determination | Mass taken [g] | Temperature program | Atmosphere | Crucible lid |

2 | 0.0049 | 25 to 400 °C at 20.0 °C/min | Nitrogen | Manually pierced x2 |
