Abstract: The present invention, therefore, is directed to an antimicrobial compositions that decreases the bioavailability of iron by introducing a higher-affinity iron-selective chelating agent capable of competing with microbial siderophores. In one aspect, the present invention relates to an antimicrobial composition including a potentiating antimicrobial composition including one or more antimicrobial agents and a chelator having a weight ratio of the antimicrobial agent to the chelator from about 1:1000 to about 1000:1.

Abstract: A composition is described that may be used in personal care products. The composition can serve as a preservative. In addition or alternatively, the composition may serve as a fragrance and/or as a coloring agent. The composition can contain an active compound, an organic acid, a solvent, and optionally a dispersant. In one embodiment, the active compound and the organic acid comprise all natural ingredients.

Abstract: Antimicrobial bispyridine amine compositions that facilitate easy application on the skin, do not penetrate the skin, are compatible with typical deodorant ingredients, and do not cause adverse effects on skin and clothing. In one aspect, the present invention relates to an antimicrobial composition including an organic acid salt of a bispyridine amine where the organic acid contains from about 4 to about 30 carbon atoms. Because the organic acid salts of bispyridine amines are large molecules, they will not easily penetrate the skin, and will stay on the surface where they were applied and where they are needed to have their effect.

Abstract: The present invention provides a cationic dispersion containing pyrithione compound, water and a cationic surfactant. The cationic surfactant is present in an amount sufficient to disperse the pyrithione in water. The dispersion is useable as an additive to personal care compositions, such as conditioners.

Abstract: A composition having effective broad spectrum preservation activity comprising a mixture of caprylyl glycol or one or more analogs thereof, or mixtures thereof with a preservative selected from the group consisting of: (1) chloroxylenol and 2-phenoxyethanol, (2) chloroxylenol and chlorphenesin, (3) chlorphenesin and 2-phenoxyethanol, and (4) chloroxylenol, chlorphenesin and 2-phenoxyethanol.

Abstract: The present invention is directed to a stable, soluble, antimicrobial composition concentrate comprising pyrithione or a pyrithione complex in an amount of from about 0.5% to about 30 weight percent, a zinc source in an amount of from about 0.1% to about 10%, and an organic amine component in an amount of from about 30% to about 80%, said percents being based upon the total weight of the composition concentrate. The invention is also directed to methods of controlling the growth of free-living microorganisms or biofilms using the antimicrobial composition of the invention, and products made using the antimicrobial composition of the invention.

Abstract: A composition comprising coated particles of a salt of pyrithione selected from the group consisting of monovalent and polyvalent pyrithione salts, and combinations thereof, partially or fully coated with a lipophilic agent. The composition is characterized by enhanced anti-fungal and anti-dandruff efficacy in shampoos. Also disclosed is a personal care composition, preferably a shampoo, containing a topical carrier and coated particles of a salt of pyrithione selected from the group consisting of monovalent and polyvalent pyrithione salts, and combinations thereof, partially or fully coated with a lipophilic agent.
