Description of key information
Additional information
Cyclohexane is considered to be readily biodegradable. Cyclohexane is also expected to have low potential for bioaccumulation based on the estimated BCF of 167 calculated using an experimental log Kow of 3.44. The estimated Koc value of 770 indicates that cyclohexane is expected to have low adsorption to suspended solids and sediment in water. Structural analysis of the cyclohexane molecule indicates that it is not expected to undergo hydrolysis in the environment due to the lack of hydrolysable functional groups. The physico-chemical properties of cyclohexane indicate that the majority of this substance will ultimately be released to the atmosphere where it is quickly photooxidised with a half-life of 52 hours.
Cyclohexane is not expected to persist in the environment because it is readily biodegradable, has a low potential for adsorption to organic matter and has a low potential for bioaccumulation. Therefore, for PBT assessment cyclohexane is considered to be not P and not B.
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).
