Description of key information

Adsorption potential is considered to be high, based on log Pow values of relevant constituents in the substance oligomerisation and alkylation reaction products of 2-phenylpropene and phenol [EC no. 700-960-7]. A log Koc value of 5.88 (Kow = 760,000) has been calculated from the Log Pow of 6.3 using the equation of Karickhoff.

Additional information

The log Pow values of the relevant constituents of the substance all fall within a range from about 3.6 to 6.3 (see CSR Chapter 1.3 or IUCLID Sect. 4.7). As relevant value for any hazard/risk assessment, a log Pow of 6.3 was selected. Based on the equation of Karickhoff (log Koc = 0.989 log Kow - 0.346) (Chemosphere, 10 (8), 833, 1981), the Koc value for the substance Oligomerisation and alkylation reaction products of 2-phenylpropene and phenol is calculated to be 760,000 (log Koc = 5.88).
