Any other information on results incl. tables
Pre-Test results
The following values were recorded:
Begin of melting process |
End of melting process |
38.3 °C |
47.8 °C |
At the test start the appearance of the test item was stated as a solid, wax like.
The test item melted to a clear liquid. After cooling down, the test item stayed liquid. On the next day the capillary was inspected, the test item was solid again.
Main Test
The capillary tube containing the test item was set into the block at 25.3 °C (first determination) and 25.7 °C (second determination). The block was heated gently with heating rate of < 1 K/min until melting started. The temperature was noted at which the first signs of melting of the test item were observed. When the substance was completely melted, the temperature was noted again.
All values and observations are presented in the following tables:
Values Main Test
Melting point/range |
Begin |
End |
First Determination |
40.2 °C (313.4 K) |
48.9 °C (322.1 K) |
Second Determination |
40.6 °C (313.8 K) |
49.2 °C (322.4 K) |
Observations Main Test

The test item melted to a clear liquid |
40.2 °C |
40.6 °C |
The test item melted to a clear liquid. After cooling down, the test item stayed liquid.
The means between both determinations give the following values for the melting range:
Melting range: 40.4 °C to 49.1 °C (313.6 to 322.3 K)
Standard deviation: 0.28 (begin); 0.21 (end)
Estimated accuracy: ± 0.4 °C
All validity criteria are presented in the following table.

Discussion
The validity criterion “difference between duplicate determinations” was met. The test item showed a melting range, no melting point. As the test item is a UVCB product, this is considered as normal.
No observations were made which might cause doubts on the validity of the study outcome. Therefore, the result of the study is considered valid.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
