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.
