Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the biodegradation studies (OECD Guideline 301 D), the registered substance is considered readily biodegradable. Two hydrolysis products were identified: acetate and 4 -tert-Butylcyclohexanol. Acetate can be considered as readily biodegradable too but insufficient data are available to assess the readily biodegradation of 4-tert-butylcyclohexanol. However, over 60% biodegradation were observed after 28 days. The parent and hydrolysis products are not persistent in the environment. The bioconcentration factor (BCF) of the registered substance was estimated using a QSAR predictions with a maximum value at 335 L/kg whole body weight, therefore the substance is not bioaccumulable according to CLP (BCF < 500) and PBT criteria (BCF < 2000). Finally, based on a read-across approach, the adsorption coefficient (log Koc) of the registered substance can be determined at 3.51 (OECD Guideline 121, EU Method C.19). This result indicates that the substance is environmentally slightly mobile (according to P.J. McCall et al., 1980).
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.
