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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 270-147-5 | CAS number: 68411-76-7 The residuum from the distillation of the products from the air oxidation of cyclohexane. It consists of alcohols, acids and lactones having carbon numbers predominantly in the range of C4 through C6.

Description of key information
Additional information
Based on the LogKow values of the components of Cyclohexane oxidized, non-volatile residue (NVR), of -0.64 - 1.92 a LogKoc of 0.6 - 2.0 was calculated using the formula for nonhydrophobics as given in TGD part 3 (INVISTA 2014 Adsorption / desorption).
Due to the variable chemical composition of the test substance, fugacity modeling cannot be performed on the substance itself; therefore, fugacity modeling was performed on the known components of NVR. Substance is an aqueous solution of various C4 -C6 mono- and dicarboxylic acids, hydroxy-acids and esters. Therefore, the mode of entering into the environment will be water. Fugacity modeling of the components indicates that 99.7 -99.8% of emissions will remain in water (INVISTA 2014, Fugacity). The volatilization from water is negligible (INVISTA 2014 Henrys Law Constant and Fugacity).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.
