1. A foamable hygroscopic vitamin and or flavonoid containing composition comprising:
- a. at least one agent selected from the group consisting of vitamins and flavonoids; and
b. at least one hygroscopic solvent at a sufficient concentration to provide an Aw value of the hygroscopic vitamin and or flavonoid containing composition of less than 0.9;
c. a foam stabilizer selected from the group consisting of at least one surface-active agent; and
at least one polymeric agent selected from the group consisting of a bioadhesive agent, a gelling agent, a film forming agent and a phase change agent and mixtures thereof; and
d. a hydrocarbon propellant at a concentration of about 3% to about 25% by weight of the total composition; and
wherein the composition is contained in a pressurized container to which a vacuum was applied prior to filling with a hydrocarbon propellant, is substantially flowable and provides a foam upon release;
wherein applying a vacuum to and filling a canister containing the composition with hydrocarbon propellant contributes to stabilize the agent against degradation.

Abstract
Vitamin and flavonoid containing compositions are provided that are stable to degradation. Stabilized compositions include one or more features including a hygroscopic solvent at a sufficient concentration to provide an Aw value of the hygroscopic vitamin and or flavonoid containing composition of less than 0.9, antioxidant flavonoids that are preferentially oxidized before the vitamin, preservatives, and hydrocarbon propellants selected to reduce the oxidation potential of the composition.
