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 &eegr;
1
and the solvent has a viscosity &eegr;
2
. The two-phase gel composition is substantially free of phosphate compounds and has a viscosity &eegr; which is greater than or equal to &eegr;
1
and which is greater than or equal to &eegr;
2
. 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.
提供了两相凝胶组合物。两相凝胶组合物是通过混合胶化酯组合物获得的,胶化酯组合物包括酯类化合物和聚合物化合物的混合物,聚合物化合物选自由三嵌段共聚物、星形聚合物、径向聚合物、多嵌段共聚物及其组合组成的组以及疏水性非极性溶剂。胶化酯组合物的粘度为 &eegr;
1
溶剂的粘度为 &eegr;
2
.两相凝胶组合物基本上不含磷酸盐化合物,其粘度大于或等于&eegr; 1;
1
且大于或等于 &eegr;
2
.两相凝胶组合物也可通过将胶化醚组合物、胶化醇组合物、胶化天然油脂组合物或它们的组合物与疏水性非极性溶剂混合而获得。两相凝胶组合物可用于悬浮各种固体、液体和/或气体。
