Two-phase gel compositions are provided. The two-phase gel compositions are obtained by mixing a gelled ester composition comprising a mixture of an ester compound and a polymer compound selected from the group consisting of triblock copolymers, star polymers, radial polymers, multi-block copolymers, and a combination thereof and a hydrophobic, non polar solvent. The gelled ester composition has a viscosity η1 and the solvent has a viscosity η2. The two-phase gel composition is substantially free of phosphate compounds and has a viscosity η which is greater than or equal to η1 and which is greater than or equal to η2. The two-phase gel compositions are also obtained by mixing a gelled ether composition, a gelled alcohol composition, a gelled naturally-occurring fat and oil composition or a combination thereof with a hydrophobic, non polar solvent. The two-phase gel compositions may be used to suspend various solids, liquids and/or gases.
