Claims
- 1. An edible, anhydrous aerosol foam composition comprising a foamable liquid oil, a foaming agent, a propellant, and dispersed solid particles, said propellant being present in an amount sufficient to produce a stable, measurable foam but insufficient to produce a spray when said composition is ejected through an aerosol valve, and said dispersed solid particles being at least 15% by weight of said composition.
- 2. The composition of claim 1 wherein said propellant comprises 1 to 10 wt. % of said composition.
- 3. The composition of claim 1 wherein said propellant is a hydrocarbon.
- 4. The composition of claim 3 wherein said propellant is propane.
- 5. The composition of claim 1 wherein said solid particles are insoluble in the other ingredients of said foam composition.
- 6. The composition of claim 1 wherein the average size of said solid particles is in the range of 50 to 100 microns.
- 7. The composition of claim 1 wherein said solid particles are selected from the group consisting of powdered skim milk, crushed nut solids, powdered flavors, sugars, sugarless sweeteners, and clays.
- 8. The composition of claim 7 wherein said solid particles comprise powdered sugar.
- 9. The composition of claim 1 wherein said solid particles comprise an exothermic agent.
- 10. The composition of claim 1 wherein said foaming agent is selected from the group consisting of lecithin, polyglycerol esters of fatty acids having an HLB value of between 4.0 and 13.0, glycerol esters of fatty acids having an HLB vaue of between 2.5 and 4.5, sorbitan esters of fatty acids having an HLB value of between 3.0 and 7.0 and mixtures thereof.
- 11. The composition of claim 9 wherein said foaming agent comprises 2 to 40 wt. % of said composition.
- 12. The composition of claim 1 wherein said foaming agent is substantially comprised of at least one water-dispersible surfactant.
- 13. The composition of claim 1 wherein at least one of said liquid oil and said solid particles comprises an active non-therapeutic agent.
- 14. The composition of claim 1 wherein said liquid oil comprises an active therapeutic agent.
- 15. The composition of claim 14 wherein said liquid oil is selected from the group consisting of mineral oil, castor oil, fish liver oils, fish body oils, and oil-soluble materials selected from the group consisting of epinephrine, isoproterenol, phenylpropanolamine base, ephedrine, amphetamine, dibucaine, dyclonine base, lidocaine, chloral hydrate, benzyl benzoate, vitamins, and steroid hormones.
- 16. The composition of claim 1 wherein said liquid oil is selected from the group consisting of soybean oil, partially hydrogenated soybean oil, linseed oil, corn oil, peanut oil, sunflower oil, cottonseed oil, olive oil, liquid petrolatums, oleic acids, lauric acids and mono- and diglyceride oils.
- 17. The composition of claim 1 wherein said propellant comprises 1 to 10 wt. % of said composition, said foaming agent comprises 2 to 40 wt. % of said composition, said solid particles comprise at least 15 wt. % of said composition and are insoluble in the other ingredients of said foam composition, and the balance of said composition is said liquid oil.
- 18. As an article of manufacture, a pressurized aerosol container, said container having therein an edible, anhydrous aerosol foam composition comprising a foamable liquid oil, a foaming agent, a propellant, said propellant being present in an amount sufficient to produce a stable, measurable foam but insufficient to produce a spray when said composition is ejected through an aerosol valve, and at least 15% by weight of dispersed solid particles.
