Description of key information

Based on data for its four main components, the partition coefficient (log Pow) of the substance EC number 905-559-2 (reaction mass of 4-vinylcyclohexene and cyclohexane and n-hexane and toluene) is expected to be in the range 2.73 to 3.93.

Key value for chemical safety assessment

Additional information

No information on the partition coefficient of the reaction mass is available. However, individual data on the four main components of the reaction mass is available from Hansch et al (2008 a, b and c) for n-hexane (CAS No. 110-54-3) (log Pow 3.9), cyclohexane (CAS No. 110-82-7) (log Pow 3.44), toluene (CAS No. 108-88-3) (log Pow 2.73 ) and from ISCS (1995) for 4-vinylcyclohexene (CAS No. 100-40-3) (log Pow 3.93).
