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.

Biocidal compositions comprising iron chelators

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.

Multi-functional composition for cosmetic formulations

A composition having effective broad spectrum preservation activity comprising benzyl alcohol, salicylic acid, sorbic acid and a compound selected from the group consisting of 1,3-propanediol, glycerin and combinations thereof.

Broad spectrum preservation blends

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.

Coated metal pyrithione particles for treatment of microorganisms

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.

Pyrithione biocides enhanced by zinc metal ions and organic amines

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.
