Melting / freezing pt.:

>= 41.1 - < 42.6 °C

Atm. press.:

1 Pa

Conclusions:

The melting point of the substance "Stearic acid, monoester with propane-1,2-diol" was evaluated using Mettler-Toledo DSC 1. The substance is fully melted at 42.6 °C and 41.1 °C for the first and second melting curve, respectively.

Executive summary:

The melting point of the substance " Stearic acid, monoester with propane-1,2-diol " was evaluated using Mettler-Toledo DSC 1. The substance is fully melted at 42.6 °C and 41.1 °C for the first and second melting curve, respectively. The peak melting temperature (second melting curve) is 39.7 °C. Thus, the measured melting point is approximately 41.1 -42.6 °C, and a paste-like solid at room temperature.

Description of key information

The test sample of the substance melts over a fairly broad range. The sample is fully melted at 42.6 °C and 41.1 °C for the first and second melting curve, respectively. The peak melting temperature (second melting curve) is 39.7 °C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:

42.6 °C
