Applicant's summary and conclusion
- Executive summary:
The available study addresses the phototransformation of cyclohexylbenzene in a 50/50 acetonitril/water solution upon exposure to sunlight for 29 days. However, the results of the "dark control" incorporated in this experiment gives insight in the hydrolysis of cyclohexylbenzene.
No significant decrease in the concentration of cyclohexylbenzene was observed. Therefore, the test substance can be considered to be hydrolytically stable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
