Description of key information

Rapid biodegradation of Oxazolidinyl ethyl methacrylate (OXEMA) was observed in a ready biodegradation test, as it passed the criterion of 60% for demonstrating “ready biodegradability” in the manometric respirometry test. Nevertheless, the rate of biodegradation was slightly slower than that required to meet the associated 10-day window criterion, therfore Oxema is “readily biodegradable, but failing the 10-day window”, according to the Introduction to Section 3 (Degradation and Accumulation) of the OECD Guidelines (OECD, 2006).

Oxema has a low log Kow (log Kow< 1), therefore has a low potential for bioaccumulation in biological tissues and a low potential for sorption to organic matter.

Based on its phys-chem properites, the substance therefore has a low potential for adsorption to soil or sediments, and a low potential to volatilize from water or soil to the atmosphere. 

 

Dipropylene glycol methyl ether degrades rapidly in the atmosphere.

Biodegradation of the DPM was confirmed by measurement

of substantial mineralization (CO2production 76%) and DOC

removal (96%) after 28 days.
