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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
The registered substance contains no organic functional groups that may hydrolyze under environmental conditions. The substance consists only of organic functional groups (notably a ketone group) that are relatively or completely inert with respect to hydrolysis. Based on the chemical structure an estimation of the hydrolysis rate is not possible. To support this statement, one stability test was performed according to a method similar to OECD Guideline 111 but without a GLP statement on a mixture of two isomers: 1-(5,5-Dimethyl-1-cyclohexen-1-yl)-4-penten-1-one, present as the major constituent at ca. 70% in the mixture, and corresponding to the registered/target substance (mono-constituent), and 1-(3,3-Dimethyl-1-cyclohexen-1-yl)-4-penten-1-one, present at ca. 20% as second constituent. In this study, the major constituent/registered substance (used as a tracer in this study) was hydrolytically stable at environmentally relevant pH. In conclusion, a GLP study is scientifically unjustified.
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.
