Octanol-Water Partition Coefficient

Octanol-Water Partition Coefficient
Definition:Defined as ratio of the concentration of compound in n-octanol and the concentration in water when the two phases are in equilibrium: KOW = cO/cW. The octanol-water partition coefficient is a measure of the lipophilicity of a compound and hence an important measure for bioaccumulation in fats. Log P, the decadic logarithm of KOW, is frequently used. KOW is related to the organic carbon-water partition coefficient as follows: KOW = KOC/0.35.
Units:dimensionless
