Key result
Remarks on result:
other: The substance showed no melting of crystalline sub-components between -90 and 90 degC.

The substance showed no melting of crystalline sub-components between -90 and 90 degC. The substance did show a glass transition temperature (amorphous compounds) at -63 degC.

Conclusions:
The substance showed no melting of crystalline sub-components between -90 and 90 degC. The substance did show a glass transition temperature at -63 degC.
Executive summary:

In a non-GLP study conducted in line with the test guideline OECD 102, the test substance showed no melting point between -90 and 90 degrees centigrade. A glass transition occured at -63 degrees centigrade.
