Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
In general, abiotic degradation of Cyclohexane, oxidized, aq. ext. is negligible. Due to its readily biodegradability, hydrolysis is a moot point. There is no information available on the photodegradation of EP-306; however, modeling of known EP-306 components indicates half-lives ranging from 0.61 -20.6 days, with major components exhibiting half-lives of about 1 -2 days.
The main degradation mode of Cyclohexane, oxidized, aq. ext. is biodegradation. In a CO2 -Evolution test according to EU Method C.4-C, Cyclohexane, oxidized aq. ext. was degraded by 79% after 28 days, indicating the ready biodegradability of the test substance (BASF AG 1997). Due to the high mineralization, no further biodegradation testing (simulation tests in water and sediment, and biodegradation testing in soil) is required for registration under REACh. Accumulation to solid soil phase and bioaccumulation are not of importance (low log Pow and log Koc). Due to the miscibility with water, volatilization is negligible. There is no information available on the fugacity of EP-306; however, modeling was performed on the known components of EP-306 assuming 100% emission to water. Fugacity modeling of the components indicates that 98 -99.8% of emissions will remain in water.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.
