Webb28 apr. 2024 · Hydrophilic Definition A hydrophilic molecule or substance is attracted to water. Water is a polar molecule that acts as a solvent, dissolving other polar and hydrophilic substances. In biology, many substances are hydrophilic, which allows them to be dispersed throughout a cell or organism. Webb10 sep. 2012 · See answer (1) Best Answer. Copy.

WebbThe most commonly used is HLB. HLB is an index of the solubilizing properties of emulsifiers and indicates the type of emulsion (o/w or w/o) that the emulsifier is best suited for (Table 2). HLB values can be calculated based on the molecular structure of the emulsifier or determined empirically. WebbHydrophilic membranes are basically nonporous films that breathe via ‘osmotic potential’ by adsorbing and desorbing the vapour molecules and then conveying them to the other side, much like cells in human body allow diffusion of monomolecular and ionic species through their membrane walls.

A hydrophile is a molecule or other molecular entity that is attracted to water molecules and tends to be dissolved by water. In contrast, hydrophobes are not attracted to water and may seem to be repelled by it. Hygroscopics are attracted to water, but are not dissolved by water.
