According to a Mackay Level I model calculation, the main target compartment for isopropylcyclohexane will be the atmosphere (99.6 %). The calculated Henry’s Law constant of 123000 Pa m³/mol at 20 °C indicates very high volatility of isopropylcyclohexane from surface waters. With a log Koc of 3.1 l/kg, a „high“ sorption potential of the substance to soil or sediment organic matter is expected (Blume scale).

 

The QSAR calculated rate constant for the OH sensitized photodegradation of isopropylcyclohexane is 13.3961E-12 cm3/(molecule * s). At 500,000 OH radicals / cm3 (typical for central Europe), this corresponds to a half-life of 28.7 hours. Hydrolysis under environmental conditions can be excluded based on structural considerations. While no ready biodegradation was observed, some adaptation and slow biodegradation are expected to occur in the environment. The main processes of removal from the environment are expected to be atmospheric photooxidation followed by biodegradation. The partition coefficient 1-octanol/water was determined as log Kow = 6.0 at 25 °C, indicating a high potential for bioaccumulation. However, due to the very high volatility from surface waters, low concentration levels are expected both in water and in biota.
