Description of key information

No biodegradation data are available for "Reaction products of cyclododeca-1,5,9-triene and dinitrogen monoxide , distillation overheads" itself.

However, while the component CAS 4904 -61 -4 showed no biodegradation in a study comparable to a closed bottle test, main component EC 701 -295 -5 attained a maximum degree of biodegradation 92 ±7% CO2/ThCO2 (mean ±SD) after an exposure period of 28 days. The degree of biodegradation at the end of the ten-day window was approximately 71 ±7% CO2/ThCO2 (mean ±SD). Hence, the required pass level for ready biodegradability in accordance to the OECD Guideline 301B i.e., at least 60% of the theoretical CO2 production must be attained within 10 days of the degradation exceeding 10% within the 28-day period of the test was accomplished.

However, since CAS 4904 -61 -4 showed no biodegradation, the whole Reaction product cannot be considered as biodegradable.
