Additional information

The adsorption coefficient (Koc) of the ethoxypropoxy propanol is <17.8 (log10 Koc<1.25) at 40 Celsius as determined by an HPLC method. The QSAR (KOCWIN version 2.0; EPISUITE) values are supportive in that they yeild a non-corrected log Koc value of 0.1507 and corrected value of -0.8534 derived from an estimated log Kow value of -1.40. These are of similar order to the experimental result.
