Vanadium oxysulphate

Flammability

Administrative data

Endpoint:

flammable solids

Data waiving:

study technically not feasible

Justification for data waiving:

the study does not need to be conducted because the substance is a liquid

Justification for type of information:

The substance is considered likely to be solid, but it is not possible to remove from water without chemical changes
The substance is inorganic and will not support combustion

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

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
