other: The cooling run shows a crystallisation at 68°C.

The cooling run shows a crystallisation at 68°C.

Conclusions:
Under the test conditions, amides, C12-18(even-numbered) and C18(unsatd.), N-hydroxyethyl shows an area of melting temperatures between 17 and 79 °C (melting of crystalline parts).
Executive summary:

The melting temperature of the amides, C12-18 (even-numbered) and C18-unsatd., N-hydroxyethyl was determined in accordance with the OECD Guideline 102 and EU Method A.1.

The practical test was performed based on the in-house test procedure VTA(S) 31X93001.02: "Melting temperature determination (Tm) of solid and liquid substances by means of DSC.

Under the test conditions, amides, C12 -18 (even-numbered) and C18-unsatd., N-hydroxyethyl shows an area of melting temperatures between 17 and 79 °C (melting of crystalline parts).

The cooling run shows a crystallisation at 68 °C.

Description of key information

The melting point was determined according to OECD Guideline 102 and EU Method A.1 (Kintrup , 2010a).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
