Additional information

Bioaccumulation studies for ethylene oxide are not available. In compliance with Regulation (EC) No 1907/2006, Annex IX, chp 9.3.2, Column 2 no study needs to be conducted if the substance has a low potential for accumulation based on a log Kow < 3. The log Kow for ethylene oxide was determined to be -0.3, which is clearly below the trigger value. Therefore, a study on bioaccumulation in organisms is not required.
