Log P is positive for lipophilic and negative for hydrophilic substances or species. The P-value only correctly refers to the concentration ratio of a single substance distributed between the …

The ratio is essentially independent of concentration, and is usually expressed in logarithmic terms (log KOW or log Poct), which are better suited for use as a free-energy based parameter …

2004年11月14日 · The octanol/water partition coefficient (Kow) is defined as the ratio of a chemical's concentration in the octanol phase to its concentration in the aqueous phase of a …

2024年6月30日 · Relationships between aquatic toxicity, chemical hydrophobicity, and mode of action: log Kow revisited. ARCHIVES OF ENVIRONMENTAL CONTAMINATION AND …

2016年1月13日 · Values of Kow are unitless and usually expressed as logKow, a relative indicator of the tendency of an organic compound to adsorb to soil and living organism. LogKow are …

The LOGKow is the equilibrium ratio of solute concentrations in two immiscible solvents; it describes how much of a given solute dissolves in octanol versus the amount which dissolves …

2019年1月9日 · The n-octanol/water partition ratio or coefficient (log Kow) and n-octanol/water distribution coefficient (log D) are key parameters in environmental risk assessment of …

The LOGKOW Database contains over 38,000 experimentally determined octanol/water partition coefficients (log P) for almost 23,000 biologically active compounds. Each record in the …

The LogKow is the equilibrium ratio of solute concentrations in octanol and water, two immiscible solvents; it measures how much a given solute dissolves in octanol versus the amount which …

Relationships between toxicity and chemical hydrophobicity have been known for nearly 100 years in mammals and fish, typically using the log of the octanol:water partition coefficient (Kow).
