The freezing temperature of the test material ranged from -10 to -7ºC ± 0.5 ºC.
Executive summary:

The freezing temperature of amides, C8-18 and C18-unsatd., N,N-bis(hydroxyethyl) was determined to range from -10 to -7 ºC ± 0.5 ºC according to ASTM D87 -87 method.

Description of key information

The freezing point was determined using a capillary viscometer (static) according to ASTM Method D87-87 (Carrillo, 2008).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-7 °C

Additional information

The freezing point ranged from -10 to -7°C.
