Dipotassium [[N,N'-ethylenebis[N-(carboxymethyl)glycinato]](4-)-N,N',O,O',ON,ON']cobaltate(2-)

Auto flammability

Link to relevant study record(s)

Reference

Endpoint:

relative self-ignition temperature (solids)

Type of information:

read-across from supporting substance (structural analogue or surrogate)

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Justification for type of information:

First, it could be shown that the complex EDTA-CoNa2 is a non-flammable solid. Neither sodium cations nor potassium cations are combustable. Thus it can be concluded that EDTA-CoK2 has the same auto flammability properties as EDTA-CoNa2.

Reason / purpose for cross-reference:

read-across source

Qualifier:

according to guideline

Guideline:

EU Method A.16 (Relative Self-Ignition Temperature for Solids)

Relative self-ignition temperature:

> 400 °C

Remarks on result:

other: at atm. pressure of 1013.25 hPa

Up to the melting point no self-heating was registered.

Conclusions:

First, it could be shown that the complex EDTA-CoNa2 is a non-flammable solid. Neither sodium cations nor potassium cations are combustable. It was shown that EDTA-CoNa2 has no self-heating properties and thus EDTA-CoK2 is not classified as auto flammable.
