Description of key information
Based on estimation with the QSAR model Aopwin Cyclacet undergoes in air rapid degradation after reaction with hydroxyl radicals or ozone. The DT50 values after reaction with hydroxyl radicals and ozone are 1.907 hours and 1.375 hours, respectively. The half-life time of the substance is < 2 days. Cyclacet will not reach the stratosphere and is therefore not considered to be a long-range transported chemical in air according to the UNECE criteria (http://www.unece.org/fileadmin/DAM/env/documents/2000/ece/eb/ece%20eb%20air.60.e.pdf). Cyclacet does not have an ozone depletion potential because it does not contain halogens and does not have the potential to reach the stratosphere (EU CLP, 1272/2008 and its amendments).
