Atm. press.:
1 013 hPa
Conclusions:
The melting temperature range of Fatty acids, C18 unsaturated, C12-14 (even numbered) alkyl esters was found to range from -1.4°C (271.8K) till 17.0°C (290.2K).

Description of key information

Based on the available experimental data derived by a fully reliable study with the registration substance the melting point is considered to be between -1.4 and 17°C. This is supported by a further reliable study leading to a melting point of 3°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
3 °C
