Abstract: The invention relates to topical delivery of bioactive agents. More particularly, the invention relates to anhydrous formulations for percutaneous absorption. The invention provides formulations that allow efficient topical delivery of high concentrations of bioactive substances for percutaneous absorption. The formulations according to the invention are generally non-irritating to the skin.

Abstract: The invention provides a topical sunscreen comprising micronized zinc oxide, titanium oxide and iron oxide, and a hydrotrope and water. The sunscreen according to the invention protects against the harmful effects of UV, IR and visible irradiation.

Abstract: Stable vitamin C (L-ascorbic acid) compositions for topical application, comprising micronized L-ascorbic acid in a substantially non-aqueous carrier having a pH greater than that of skin, and preferably not lower than approximately 5.5 and not greater than approximately 7.5, are described. The composition may consist essentially of L-ascorbic acid and capric/caprylic triglycerides or may further comprise papain as an enzymatic exfoliant in addition to humectants, emollients, viscosity-increasing agents, surfactants, and preservatives. Methods of preparing the micronized L-ascorbic acid for use in the described formulations, by a “wet” micronization process, are also described. The compositions are useful as UV protectants, promoters of collagen synthesis and in the removal and/or treatment of wrinkles.

Abstract: Micronized zinc oxide skin protector formulations comprising between about 8% and 40% zinc oxide. These compositions preferably comprise micronized zinc oxide, preferably obtained via a “wet” micronization process in oil, and also preferably include agents that block or screen light in the visible and/or infrared ranges, and also preferably include hydrotropes and humectants to aid in the dissipation of heat caused by the irradiation of light in the visible and/or infrared ranges, and alleviate the photo-damage and/or heat damage associated with such irradiation. These compositions are preferably readily absorbable, transparent, non-irritating, non-comedogenic and are hypo-allergenic. The compositions may comprise additional ingredients such as biological additives (e.g., botanicals and herbals).

Abstract: Cosmetic compositions for topical use that comprise an exfoliating enzyme for use in removal of at least a portion of the dead skin cells from the outer layer of skin, in conjunction with one or more botanicals, the delivery of which to subsurface layers and cells thereof of the skin is enhanced by the presence of the exfoliating enzyme. These compositions, including gels, lotions, and creams, are gentle, non-irritating and enhance the penetration of biological additives into the subsurface skin layers relative to currently commercially available compositions.
