2,4,4-trimethylpentene is not readily biodegradable with a reported 1.6% biodegradation within 28 days.
The key and supporting studies by Hydrotox (2004) and Wildlife International (2006) are GLP compliant and follow standard guidelines. They both support the characterisation of 2,4,4 -trimethylpentene as not readily biodegradable. In the EU RAR (2008), it is concluded that, based on the available information a sound assessment of biodegradation is not possible, so as a worst-case 2,4,4-trimethylpentene has to be assessed as not biodegradable. The data are supported by the results from the QSAR estimations using the BIOWINand BioHC models.
