Silver (III) periodate for improved antimicrobial properties
US Patent Application 20120328713
Publication date: Dec. 27, 2012
Inventors: ME Olson, NA Allan, AM Omar, JJ Anderson, P Nadworny and MW Harding

Described by this invention are methods and compositions for preventing or reducing microbial contamination using a silver (III) periodate as antimicrobial active. In a preferred embodiment, the silver (III) periodate is used in a coating upon a medical device or implant to confer coating uniformity and antimicrobial efficacy. Also provided is a method of synthetizing the silver (III) periodate. The compositions and methods of the present invention are also effective as a preservative for plant-based cosmetics, as an ingredient or incorporated into the packaging, among other applications.

Alkylaminoalkyl oligomers as broad-spectrum antimicrobial agents
US Patent Application 20120328683
Publication date: Dec. 27, 2012
Inventors: Z Song and T Deisenroth

The present application relates to oligomeric antimicrobial compounds and compositions comprising them. The oligomers are formed by polymerizing aminoalkyl (meth)acrylate or aminoalkyl (meth)acrylamide monomer(s). In addition to imparting materials with broad spectrum antimicrobial activity, the oligomers can impart antimicrobial activity to substrates such as hair and skin.

Lactobacillus species for selective microbial growth, inhibition
US Patent Application 20120328586
Assignee: Organobalance GmbH
Publication date: Dec. 27, 2012

This invention describes microorganisms that are, in a first aspect, able to stimulate the growth of resident skin microbial flora without stimulating the growth of transient pathogenic microflora. In a second aspect, the microorganisms are able to inhibit the growth of microorganisms of the transient pathogenic skin microflora without inhibiting the growth of resident skin microflora. Also described are compositions comprising such microorganisms in cosmetic, prophylactic or therapeutic applications. The microorganism of the present invention is preferably a Lactobacillus species. The lactic acid bacteria of the present invention are preferably rod-shaped or spherical, varying from long and slender to short bent rods; preferably immotile and/or asporogenous; and produce lactic acid as a major or sole product of fermentative metabolism.

Mild, non-drying skin sanitizing compositions
US Patent Application 20120328548
Publication date: Dec. 27, 2012
Assignee: Yissum Research Development Company of the Hebrew University of Jerusalem Ltd.

Provided in this patent are novel compositions exhibiting highly effective antiviral, antimicrobial and/or antifungal activity for sanitizing and/or disinfecting inanimate or animate surfaces. Preferred compositions include a synergistic combination of an alcohol, docusate, geraniol and, optionally, menthol. The compositions have high antimicrobial activity yet are mild, non-irritating, quick-drying, non-sticky and not drying to the skin. Processes for manufacturing and using the compositions are also disclosed.
