Description of key information
Based on the results of a GLP study performed according to OECD 301D guideline, OO-t-Butyl-O-(2-ethylhexyl)monoperoxycarbonate should be classified as readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
In order to assess the biotic degradation of OO-t-Butyl-O-(2-ethylhexyl)monoperoxycarbonate, a ready biodegradability test was performed in a Closed Bottle test according to slightly modified OECD (OECD TG 301), EU and ISO Test Guidelines, and in compliance with the OECD principles of Good Laboratory Practice (Van Ginkel, 2013). OO-t-Butyl-O-(2-ethylhexyl)monoperoxycarbonate did not cause a reduction in the endogenous respiration. The test substance is therefore considered to be non-inhibitory to the inoculum. OO-t-Butyl-O-(2 -ethylhexyl)monoperoxycarbonate was biodegraded by 67% at day 28 in the Closed Bottle test. Hence this substance should be classified as readily biodegradable. The test is valid as shown by an endogenous respiration of 0.7 mg/L and by the total mineralization of the reference compound, sodium acetate. Sodium acetate was degraded by 85% of its theoretical oxygen demand after 14 days. Finally, the most important criterion was met by oxygen concentrations >0.5 mg/L in all bottles during the test period. Another GLP study according to OECD method 301 F shows that OO-t-Butyl-O-(2-ethylhexyl)monoperoxycarbonate reached a maximum biodegradation level of 42% in 58 days and 39.8% in 28 days.
