Lyophilic sols(solvent loving): They are those in which the dispersed phase exhibits a definite affinity for the dispersion medium(liquid) or the solvent.For eg. Dispersion of starch, gum, & protein in water.The affinity of sol particles for the medium is due to hydrogen bonding with water(dispersion medium). They may have little or no charge at all & they donot exhibit Tyndall effect.These sols are reversible in nature i.e., if two constituents of the sol are separated by any means (such as evaporation), then the sol can be prepared again by simply mixing the dispersion medium with the dispersion phase and shaking the mixture.
