Administrative data

Endpoint:
oxidising solids
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with oxidising properties and hence, the classification procedure does not need to be applied
the study does not need to be conducted because the organic substance contains oxygen or halogen atoms which are chemically bonded only to carbon or hydrogen and hence, the classification procedure does not need to be applied

Results and discussion

Applicant's summary and conclusion

Conclusions:
A test item is considered an oxidizing substance when the burning time of a mixture of the substance and cellulose in a 4:1 or 1:1 sample-to-cellulose ratio (by mass) is less than or equal to the mean burning time of a 3:7 reference mixture (by mass) of potassium bromate and cellulose. None of the components of the test item does contain groups that act as an oxidizing agent. The oxygen and halogen atoms that are present in the molecular structure of the test item are chemically bonded to carbon or hydrogen. The test item contains a NaOH, which does not have oxidizing properties. In conclusion, the test item has no oxidizing properties.
Executive summary:

A test item is considered an oxidizing substance when the burning time of a mixture of the substance and cellulose in a 4:1 or 1:1 sample-to-cellulose ratio (by mass) is less than or equal to the mean burning time of a 3:7 reference mixture (by mass) of potassium bromate and cellulose. None of the components of the test item (= REACH substance) does contain groups that act as an oxidizing agent. The oxygen and halogen atoms that are present in the molecular structure of the test item are chemically bonded to carbon or hydrogen. The test item contains a NaOH, which does not have oxidizing properties. In conclusion, the test item has no oxidizing properties.
