Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Justification for type of information:
Performed to guidelines, 2017
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
DSC analysis
Principles of method if other than guideline:
The water-based commercial sample was dried under a nitrogen purge to remove water prior to analysis.
GLP compliance:
not specified
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Physical State liquid
CAS # 83682-78-4
EU # 280-518-3
Sample ID 53461J16
Key result
Melting / freezing pt.:
> -46 - < 10 °C
Atm. press.:
ca. 1 atm
Decomposition:
ambiguous

Although appearing a waxy solid when dried, it appears to behave as a liquid at room-temperature with a melting range < 10 C

There was no clear melting transition.

Conclusions:
Although appearing a waxy solid when dried, it appears to behave as a liquid at room-temperature with a melting range < 10 C
There was no clear melting transition.
It is also possible that there was retained water in the sample and the melting of water is partly responsible for the result.
The substance is supplied in water, so this figure is somewhat academic

Description of key information

Although appearing a waxy solid when dried, it appears to behave as a liquid at room-temperature with a melting range < 10 C

There was no clear melting transition.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
10 °C

Additional information

The waxy solid softens, but there is no clear melting transition; it is also possible that there was retained water in the sample and the melting of water is partly responsible for the result.

The substance is supplied in water, so this figure is somewhat academic
