Description of key information

The log Kow of C20-22 alpha olefins has been measured as >6 for the major components

Key value for chemical safety assessment

at the temperature of:
20 °C

Additional information

Webb (2001) tested a substance composed of C20-22 alpha olefins, it is therefore considered appropriate to read across from that test substance to icos-1-ene. The octanol water partition coefficient was determined following a standard method conducted to GLP and is therefore considered suitable as a key study for this endpoint. This value is supported by the calculated log Kow of 10.03 and 11.65 (USEPA, 2008; Karickhoff et al, 2009).
