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:
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
