Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Phototransformation in air

Description of key information
No experimental data on the photo-transformation of the substance in the air is available. Based on estimation with the QSAR model AOPWIN (v1.93), the substance using its SMILES notation CC1C(C)(C)C2CCC3CC(C)(C)OC3C2C1(C)C undergoes in air rapid degradation after reaction with hydroxyl radicals (ozone could not be estimated). The DT50 value after reaction with hydroxyl radicals is 4.675 hours (based on 12-hour time frame and 1.5E+06 OH radicals/cm3, default settings in AOPWIN). Based on the half-life, the substance will not reach the stratosphere and is not a long-range transported chemical in the air. The substance 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, EC no 1272/2008 and its amendments). The half-life in the air is not used in the risk characterisation because it is not an experimental value.
Key value for chemical safety assessment
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.
