Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No relevant data available. The equilibrium partitioning method has been used to assess the hazard potential of Cylcohexanone towards terrestrial organisms. 

Key value for chemical safety assessment

Additional information

In Annex X of the Regulation (EC) No 1907/2006 REACH concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), it is suggested, that "in the absence of toxicity data for soil organisms, the equilibrium partitioning method may be applied to assess the hazard to soil organisms. The choice of the appropriate tests depends on the outcome of the chemical safety assessment. In particular for substances that have a high potential to adsorb to soil or that are very persistent, the registrant shall consider long-term toxicity testing instead of short-term. These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely."


 


For Cyclohexanone there are no appropriate data on terrestrial toxicity available for a derivation of PNECsoil. The substance however, exhibits a low potential for adsorption, is not bioaccumulative and readily biodegradable. Furthermore, results of aquatic tests revealed no harmful effects of Cylcohexanone, and by thereby suggesting little hazardous potential towards soil organisms. Therefore, the equilibrium partitioning method has been used to assess the hazard potential of Cylcohexanone towards soil organisms.
