Abstract: The present invention relates to enhanced efficacy antiperspirant salts containing strontium and an amino acid or a hydroxy acid and particularly to stabilized aqueous solutions of such salts. The present invention also embraces methods of making these antiperspirant salts and solutions and compositions containing same.
Abstract: A cost effective process is provided for making stable, efficacious, amino acid and polyhydric alcohol free concentrated aqueous aluminum zirconium salt solutions. Absence of amino acid, low iron content and low trace metal impurity levels improve compatibility with fragrances and minimizes the probability of the product color change and possibly fabric staining significantly. The novel aluminum zirconium actives also minimize iron contribution to underarm area that supports growth of microflora which is responsible for axillary malodour by the biotransformation of nonodorous precursors present in perspiration. The astringent complexes of the present invention may be obtained in solution or dry powder form. As a result, the complexes are satisfactory for use in any of wide variety of conventional antiperspirant forms.

Abstract: An amino acid free stable aluminum zirconium polyhydric alcohol aqueous solution having a high anhydrous antiperspirant solid concentration and a high percentage of low molecular weight aluminum species, i.e., containing 60% or more of band IV peak area based on high pressure liquid chromatography, is prepared by adding a zirconium salt to an aqueous polyhydric alcohol solution of a basic aluminum chloride.
Abstract: Exposure of human skin to ultraviolet (UV) radiation from the sun not only induces the production of enzymes (matrix metalloproteinases) that degrade collagen, but also inhibits the synthesis of new collagen by inhibiting the synthesis of procollagen. This UV-induced inhibition of the synthesis of collagen can be prevented by the topical application of a retinoid or c-JUN inhibitor to the skin prior to exposure to UV radiation.

Abstract: The present invention provides methods of treating early morning pathologies using a time-specific controlled release dosage formulation which is administered prior to sleep, and which permits or achieves delivery of a pharmaceutically active agent effective for the treatment of the specific early morning pathology to be treated, at about the time of awakening. The time-specific controlled release dosage formulation comprises (1) a core including the pharmaceutically active agent(s) effective for the treatment of the early morning pathology, and (2) a swellable polymeric coating layer substantially surrounding the core. The swellable polymeric coating layer delays the release of the pharmaceutically active agent from the core for a predetermined period of time dependent upon the thickness of the swellable polymeric coating layer, to effect delivery of the pharmaceutically active agent at about the time of awakening.
