Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No studies on adsorption are available for methylcyclohexane (CAS No. 108 -87 -2). However, the substance is not expected to sorb significantly to organic matter in soil, sediment, and wastewater solids based on calculated log Koc values of 2.37 and 3.37. Furthermore, Methylcyclohexane exhibits a very high volatilisation potential (HLC = 34300 Pa*m3/mole) as provided by a QSAR estimation.

Fugacity-based multimedia modelling provides basic information on the relative distribution of a chemical between selected environmental compartments (i.e. air, soil, water, sediment, suspended sediment, and biota). A widely used fugacity model is the EQC (Equilibrium Criterion) Level I model. This model requires the input of basic physico-chemical parameters (i.e. molecular weight, melting point, vapor pressure, water solubility, log Kow). Available results of the Mackay Level I environmental distribution model show that methylcyclohexane has the potential to partition primarily to air. This result can be explained by the high volatility of methylcyclohexane.
