Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance to Regulation (EC) No. 1907/2006, Annex IX and X, Column 2, 9. 4, as the RCR soil is < 1 no further effects of methylcyclohexane on terrestrial organisms need to be investigated and tests are therefore not required.
Key value for chemical safety assessment
Additional information
In accordance with Regulation (EC) No 1907/2006, Column 2 of Annex IX and X, section 9.4 toxicity tests on terrestrial organisms does not need to be investigated if the outcome of the chemical safety assessment shows no indication of risk on terrestrial organisms from exposure to the substance in question. In a first step, the soil PNEC for methylcyclohexane has been derived using aquatic PNECs and the equilibrium partitioning method (EqP). The risk characterization ratio (RCR) has demonstrated that there is no indication of risk i.e. PEC/PNEC soil < 1 from current exposure conditions to methylcyclohexane.
Furthermore, considering the high volatility, the substance is expected to be rapidly removed within sewage treatment plants. As a consequence, direct and indirect exposure of soil organisms is unlikely to occur. In addition, due to the high volatility, it is unlikely that a constant exposure concentration could be achieved in soil toxicity tests.
In conclusion, in accordance to Regulation (EC) No. 1907/2006, Annex IX and X, Column 2, 9. 4, as the RCR soil is < 1 no further effects of methylcyclohexane on terrestrial organisms need to be investigated and tests are therefore not required.
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.
