Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
Water based material tested. Earlier work demonstrates that if heating to remove water, the sample does decompose.
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Principles of method if other than guideline:
DSC method over the range of -30 to 100 C
GLP compliance:
no
Other quality assurance:
other: Laboratory is GLP accredited
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Batch HMK/370/38/1
Earlier work demonstrates that if heating to remove water, the sample is unstable so not possible to isolate
Key result
Melting / freezing pt.:
-0.84 °C
Atm. press.:
1 018 mBar
Decomposition:
no
Conclusions:
Material containing water freezes close to the freezing temperature of water.
Earlier work demonstrates that if heating to remove water, the sample does decompose.

Description of key information

Material containing water freezes close to the freezing temperature of water.

Earlier work demonstrates that if heating to remove water, the sample does decompose.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-0.8 °C
