  • Patent number: 9278066
    Abstract: A stable topical alcohol-free aerosol foam containing one or more keratolytic agents is provided. The foam-forming formulation is an oil-in-water emulsion which contains one or more hydrofluoroalkane (HFA) propellants and one or more keratolytic agents. The keratolytic agent may be present in either phase of the emulsion or dispersed in the emulsion. The oil phase may consist at least in part of the HFA propellant. The foam is stable on the skin for at least 5 minutes at body temperature and disappears into the skin upon rubbing or after prolonged standing. The formulations may not contain additional co-solvents or non-HFA co-propellants. The formulations demonstrate reduced intensity of the odor and/or color associated with the keratolytic agent(s) as compared to conventional formulations containing keratolytic agents.

  • Patent number: 8975295
    Abstract: Methods of altering properties of tissues, by providing an effective modifying amount of zinc, which may be in the form of zinc ions. This is accomplished through the use of topical compositions containing one or more zinc-containing components such as salts and/or other zinc compounds or complexes, particularly zinc acetate. Altering properties of tissues includes increasing or decreasing fatty tissue, increasing or decreasing epidermal thickness, increasing elastin content, and preventing or treating gum regression or atrophy. Also disclosed is the provision of a contact lens coated with a zinc-containing material, to improve vision by increasing elastin content of the lens of the eye through release of zinc ions.
