Lipophilicity is defined as a fundamental property of compounds that influences solubility, permeability, and protein binding, reflecting a compound's preference for Van der Waals interactions with organic molecules over hydrogen bonds or dipolar interactions with water.

April 20, 2024 - Hydrocarbon-based surfactants are ... and a lipophilic "end", usually a long chain hydrocarbon fragment, referred to as their "tail". They congregate at low energy surfaces, including the air-water interface (lowering surface tension) and the surfaces of the water-immiscible droplets found in oil/water emulsions (lowering interfacial tension). At these surfaces they naturally orient themselves ...

August 28, 2025 - Lipophilic nature describes a substance's ability to dissolve in fats, improving absorption through biological membranes.

March 5, 2026 - Lipophilic nature, as described in health sciences, refers to a compound's solubility in lipids or fats rather than water. This characteristic influences a substance's behavior, such as a cosurfactant needing a hydrophilic-lipophilic balance value less than 8 in self-emulsifying drug delivery ...

June 5, 2024 - Being lipophilic means being highly affinitized with fat and lipid-soluble substances. This physicochemical characteristic illustrates a partitioning equilibrium of solute molecules and is related to bioaccumulation, between water and an immiscible ...

Drugs with higher lipophilicity may have lower solubility in water, which may limit their suitability for oral administration. Due to the hydrophobic nature of many protein binding pockets, increasing the lipophilicity of ligands (drugs) typically enhances their affinity with the target, but ...

Lipophilicity, or “fat friendly” as derived from the Greek, is described as the degree to which an organic molecule dissolves in fat, oil, or nonpolar organic solvents (i.e., hexanes), as opposed to polar solvents (i.e., water).

March 4, 2008 - This chapter contains sections titled: Chemical Nature of Lipophilicity Chemical Concepts Required to Understand the Significance of Lipophilicity Molecular Charges and Dipoles Intermolecular...

LIPOPHILIC definition: 1. Lipophilic substances are attracted to lipids (= fats, oils, or waxes that dissolve in alcohol…. Learn more.

August 4, 2026 - Other articles where lipophilicity is discussed: surfactant: hydrophilic (water-soluble) and partly lipophilic (soluble in lipids, or oils). It concentrates at the interfaces between bodies or droplets of water and those of oil, or lipids, to ...

Briefly, NADES species (e.g., mannose-dimethylurea-water, 2:5:5, mole/mole) formed matrices to 1) dissolve lipophilic molecules (e.g., curcumin), 2) load lipophilic molecule(s) into the hydrogel, and 3) spontaneously vacate from the system. NADES species ubiquitously occur in natural sources, and a crude extract is a mixture of the NADES species and bioactive metabolites.

October 1, 1999 - Lipophilicity and cardiovascular outcome in patients with CHF.

December 12, 2023 - Definition and Examples: Lipophilic toxins are compounds that tend to dissolve in fats, oils, and lipids rather than water. Mycotoxins, produced by certain fungi, are prime examples of such toxins.

A substance is lipophilic if it is able to dissolve much more easily in lipid (a class of oily organic compounds) than in water.

June 27, 2025 - Lipophilicity refers to the chemical property of a molecule that describes its ability to dissolve in fats, oils, lipids, and non-polar solvents versus its ability to dissolve in water (a polar solvent).

March 30, 2020 - However, early reports suggested that C12-G+ inhibits vital metabolic enzymes, thus exerting its primary toxic effect inside the fungal cell30,31. Such activity inside the cell requires passive diffusion through the plasma membrane into the cell. Membrane permeability depends on the lipophilic nature of a molecule, with positive LogP values indicating easier passage through bio-membranes21.

Lipid-based formulations enhance drug solubilization both by initially presenting the drug in a solubilized form and by preventing drug precipitation by altering the nature of both exogenous (formulation-derived) and endogenous solubilizing species in the intestinal milieu. Second, by recruitment of intestinal lymphatic drug transport (and reduced first-pass metabolism). Highly lipophilic drugs (Log P > 5, triglyceride solubility >50 mg per g) can be transported to the systemic circulation by the intestinal lymphatic system rather than the portal vein blood following oral delivery.

March 27, 2026 - Lipophilicity is defined as the affinity of a drug for a lipid environment. It has become a critical parameter in the pharmaceutical industry, which indicates the relationship of a drug with their biological, pharmacokinetic, and metabolic ...

April 4, 2026 - Lipophilic substances are defined as those that have an affinity for fats and oils, meaning they tend to mix well with lipid environments. In the context of niosomal bilayers, these substances become integrated into the lipophilic sphere, playing a significant role in their structure and ...
