Conclusion on classification

For the ecotoxicological studies the test item used corresponds to 50.6% of diisopropyl peroxydicarbonate in 49.4% of ethyl acetate. Its active ingredient, diisopropyl peroxydicarbonate, hydrolyses rapidly into n-isopropanol. Test samples were therefore monitored for n-isopropanol and the results have been converted from isopropanol to the active ingredient of the test item.


From the three acute tests available the lowest EC50 value was measured in OECD 201 on algae with EC50= 0,27 mg/L.


With this result, the active ingredient and thus the test item is considered as very toxic to aquatic organisms, acute category 1 (H400) with acute M-factor = 1.


 The test item is considered as not ready biodegradable.


Chronic toxicity data is available only for algae given an EC10 = 0,22 mg/L. Based on this value, the test item should be classify as aquatic chronic 2 (H411). Nevertheless, even if no toxicity was observed on the acute toxicity for fish, an EC50 > 0.72 mg/L was determined. Taking into account this value, the test item should be classify as aquatic chronic 1 (H410). This latest chronic classification is retained for this test item. No M-factor is needed.
