Foamable compositions are disclosed. The compositions contain one or more active ingredients combined with a foaming agent and optionally one or more surface tension adjusting agents. The foaming agent may comprise, for instance, a derivatized dimethicone. The surface tension adjusting agent, on the other hand, comprises a chemical species that either increases or decreases the surface tension of the composition within a desired range so that the composition is readily foamable. In this manner, active ingredients can be incorporated into the compositions that are typically hard to foam. Such ingredients include cleaning solvents and various skin care agents. Of particular advantage, foamable compositions can be formulated in accordance with the present disclosure that contain relatively small amounts of water such as less than about 20 percent by weight, such as less than about 10 percent by weight. In other embodiments, the composition can be completely anhydrous.
