Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study with acceptable restrictions
Justification for type of information:
Although guideline study performed, the work was done using the commercial grade material supplied as ca 50% actives.
It is not considered possible to isolate from water without causing chemical composition changes
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
Freezing point
GLP compliance:
yes (incl. QA statement)
Type of method:
method to determine freezing temperature
Melting / freezing pt.:
< -20 °C
Atm. press.:
ca. 1 atm
Decomposition:
no

Freezing temperature: <-20 °C (<253 K)

Conclusions:
Freezing temperature: <-20 °C (<253 K) for commercial grade material as supplied in 50% water solution.
