Cobalt, [29H,31H-phthalocyaninato(2-)-N29,N30,N31,N32]-, sulfonated, sodium salts

Flash point

Administrative data

Endpoint:

flash point of flammable liquids

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
The substance is a powder with no melting point.

Conclusions:

The DSC shows an endothermic peak which covers a wide range between 39°C and 222°C, with a peak at 139°C.

Executive summary:

A determination of the thermal stability of the test item by DSC (Differential Scanning Calorimetry) was performed with a DSC Mettler TOLEDO DSC 1, using a perforated crucible.

The DSC shows an endothermic peak which covers a wide range between 39°C and 222°C, with a peak at 139°C. This endothermic peak is considerably broad, over 180°C. It does not seems to be melting point. It might be a relaxation phenomena due to the evaporation of water.
