Foamable sanitizing compositions are disclosed. The compositions contain alcohol, water, a foaming agent, and a foam strengthening agent. The foaming agent which may comprise a derivatized dimethicone has been found to cause the alcohol solution to foam even though alcohol has various defoaming properties. The foam strengthening agent may comprise, for instance, a betaine that contains organic molecules wherein at least 90% of the organic molecules have a carbon chain length of 18 carbon atoms or greater. In one embodiment, the composition can be contained in a non-aerosol dispensing container that mixes the composition with air causing the composition to foam when dispensed.
