Endpoint:
oxidising solids
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
equivalent or similar to guideline
Guideline:
EU Method A.17 (Oxidising Properties (Solids))
Deviations:
not specified
GLP compliance:
not specified
Sample tested:
other: 5g of cellulose mixed with 10g of aqueous tetrachloroauris acid solution
Parameter:
preliminary test
Remarks on result:
other: no vigorous burning observed
Interpretation of results:
GHS criteria not met
Conclusions:
Tetrachloroauric acid solution does not appear to have oxidising properties as no 'vigorous' burning was observed.
Executive summary:

This information has been supplied in the form of a statement letter from the company. It is considered suitable for use as supporting data to waive this endpoint. Tetrachloroauric acid solution does not appear to have oxidising properties as no 'vigorous' burning was observed.

Description of key information

Tetrachloroauric acid solution does not appear to have oxidising properties as no 'vigorous' burning was observed. This is considered relevant also for the solid form. Taking this into account the oxidising properties of the test item have been predicted negative.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

This information has been supplied in the form of a statement letter from the company (Johnson Matthey 2010). It is considered suitable for use as supporting data to waive this endpoint. Tetrachloroauric acid solution does not appear to have oxidising properties as no 'vigorous' burning was observed. This is considered relevant also for the solid form.

The structure contains a halogen therefore testing would be required. However, there are no oxohalogen groups within the structure and a preliminary test undertaken by Johnson Matthey (2010) clearly shows that the test item does not possess oxidising properties. Taking the above into account the oxidising properties of the test item have been predicted negative.

Justification for classification or non-classification

Tetrachloroauric acid is not classified for oxidising properties. The structure contains a halogen therefore testing would be required. However, there are no oxohalogen groups within the structure and a preliminary test undertaken by Johnson Matthey (2010) clearly shows that the test item does not possess oxidising properties. Taking the above into account the oxidising properties of the test item have been predicted negative.
