Key value for chemical safety assessment

Additional information

In accordance with Column 2 of REACH Annex VIII, the adsorption/desorption screening test (required in Section 9.3.1) does not need to be conducted as the substance is readily biodegradable. No reliable measured adsorption data are available for the substance. A Koc value of 23100 L/Kg was obtained for pentadecan-1 -ol using a well-established calculation method. The result is considered to be reliable and acceptable for use in environmental exposure modelling for pentadecanol, branched and linear.
