LogP—Making Sense of the Value - ACD/Labs

a positive value for logP denotes a higher concentration in the lipid phase (i.e., the compound is more lipophilic). LogP = 1 means there is a 10:1 partitioning in Organic : Aqueous phases. Although logP is a constant, its value is dependent on the choice of the organic partitioning solvent and, to a lesser degree, on the conditions of measurement.a positive value for logP denotes a higher concentration in the lipid phase (i.e., the compound is more lipophilic).
