WebFeb 1, 2016 · Soil Adsorption Coefficient (Kd/Koc) and Chemical Risk Assessment Kd or Koc measures the mobility of a substance in soil. A very high value means it is strongly adsorbed onto soil and organic matter and does not move throughout the soil. A very low value means it is highly mobile in soil. WebWhat does a low logP mean? A negative value for logP means the compound has a higher affinity for the aqueous phase (it is more hydrophilic); when logP = 0 the compound is equally partitioned between the lipid and aqueous phases; a positive value for logP denotes a higher concentration in the lipid phase (i.e., the compound is more lipophilic).

WebNov 3, 2015 · So a high logP would mean the molecule is mostly in the organic dioxane layer rather than water. E.g a molecule with a logP of 2 would prefer the organic layer 100 times more than water, and would be considered hydrophobic/lipophilic. Hexane logP=4.15, very hydrophobic and almost all of it will stay in the organic layer.
