Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
test procedure in accordance with generally accepted scientific standards and described in sufficient detail
Qualifier:
no guideline followed
Principles of method if other than guideline:
Direct observation of the material
Attempts were made to remove water.
GLP compliance:
no
Specific details on test material used for the study:
Production material was taken and attempts made to remove water.
Analysis demonstrated ca 36 - 37% actives in water
Physical state at 20°C and 1013 hPa:
liquid
Remarks:
As supplied
Key result
Form:
liquid
Colour:
Green
Substance type:
inorganic

Attempts were made to remove water by heating, but colour change indicated a potential change in oxidation state. The registered substance is of mixed valancy.

Even if managing to obtain dry material, it is very hygroscopic and not possible to handle without absorbance of water.

Conclusions:
Not possible to remove from water without apparent degradation / oxidation

Description of key information

Not possible to dry without colour change, indicating degradation.

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:
liquid
