WebbAlcohols contain the polar -OH group. Short chain alcohols are water soluble and so hydrophile, while long chain alcohols are less water soluble, they are hydrophob, because most of the molecule contains apolar bonds. Molecules with ionic bonds, like NaCl are hydrophilic, but not necessary water soluble (e.g. AgCl is poorly soluble in water).

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. 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. eso lowest level thieves guild
