Description of key information
Isopropyl Methyl-2-Butyrate undergoes 63% biodegradation after 28 days in the test conditions. Biodegradation starts on day 3 and reaches 58 % at the end of the 10-day window (days 3 to 13).
Though these results are close to the pass level (60% at the end of the 10-day window), Isopropyl Methyl-2-Butyrate should be regarded as not readily biodegradable according to this test. However it may be regarded as inherently biodegradable but as the substance showed 63% biodegradability and was within 2% of the pass level at the end of the 10-day window, under REACH it may be considered to be readily biodegradable but failing the 10 day window.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
