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 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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
The statement as presented in the study report was based on the molecular structure of the substance. Full text of the statement: "A test item is considered an oxidizing substance(1) 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.
The composition of the test item is shown in Paragraph 4.1. None of the components of the test item does contain groups that act as an oxidizing agent. The oxygen atoms that are present in the molecular structure of the test item are chemically bonded to carbon or hydrogen. In conclusion, VALSARTAN/DS has no oxidizing properties"

(1) According to the UN O.1 guideline.
