Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
test procedure in accordance with national standard methods with acceptable restrictions
Justification for type of information:
Not possible to determine the melting point of the substance as impossible to dry without chemical changes
Qualifier:
equivalent or similar to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Principles of method if other than guideline:
As the production grade matrial is liquid, attempts were made to freeze by placing a small sample in a domestic (laboratory) freezer at about - 15 C
GLP compliance:
no
Type of method:
method to determine freezing temperature
Specific details on test material used for the study:
ca 36 - 37% active in water
Not possible to dry.
Key result
Melting / freezing pt.:
< -15 °C
Atm. press.:
ca. 1 atm
Decomposition:
no
Conclusions:
The production grade material as ca 36% actives in water freezes < -15 C
It is not possible to remove from water without chagning the oxidation state.

Description of key information

The production grade material as ca 36% actives in water freezes < -15 C

It is not possible to remove from water without chagning the oxidation state.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-15 °C
