Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Log Pow is cited as being  2.78 in a Peer Reviewed database for 4a,4,7,7a-tetrahydro-4,7-methanoindene.    QSAR predictions provide a value of 3.38 for 3a,4,5,6,7,7a-hexahydro-4,7 -methano-1H-indene . 

Key value for chemical safety assessment

Additional information

Measured Data was not available for 3a,4,5,6,7,7a-hexahydro-4,7 -methano-1H-indene, therefore data has been read across from 3a,4,7,7a-tetrahydro-4,7 -methanonoindene and supported by a QSAR calculation for 3a,4,5,6,7,7a-hexahydro-4,7 -methano-1H-indene.

The octanol/water partition coefficient (log Pow) for the test substance is 2.78. No information on the primary source of this data or the methods used is available. However, this information is taken from a reliable peer reviewed database and so can be considered reliable and suitable for use as the key study for this endpoint.(ICSC 2005) The data supports the study identified in the OECD SIDS which was unavailable for review. (MITI 1997) QSAR modeling (USEPA 2008 KOWWIN v1.67a) predicts a value of 3.38
