Abstract:
Polypropylene fibers and devices that include a fatty acid monoglyceride added to the polypropylene as a melt additive are described. A hydrophilic enhancer material can be advantageously added to the polypropylene as a melt additive to enhance the hydrophilicity of the fibers and devices. An antimicrobial enhancer material can be added to the fibers to enhance the antimicrobial activity.

Antimicrobial compositions, especially those useful when applied topically, particularly to mucosal tissues (i. e. , mucous membranes), including, in particular, an antimicrobial lipid component, such as a fatty acid ester, fatty ether, or alkoxide derivative thereof. The compositions can also include an enhancer component, a surfactant, a hydrophobic component, and/or a hydrophilic component. Such compositions provide effective topical antimicrobial activity and are accordingly useful in the treatment and/or prevention of conditions that are caused, or aggravated by, microorganisms (including viruses).

US Classification:
424616000, 514568000
Abstract:
The present invention provides a composition, comprising: greater than about 0.1% by weight hydrogen peroxide; an aromatic acid component; surfactant; optionally, a solvent; and a carrier. The composition of the invention is useful as a disinfecting composition for killing microorganisms such as bacterium (including Mycobacterium), spores and fungi. The composition provides a pathogenic bacteria kill rate of 99.9% in about 30 seconds when bacteria are exposed to the composition and is effective in providing a kill of 10with two minutes or less. Moreover, the compositions of the invention are generally more resistant to catalase deactivation than, for example, an aqueous solution of hydrogen peroxide. The concentration of hydrogen peroxide within the composition may range from about 1% by weight to about 7% by weight and the concentration of aromatic acid component may range from about 0.1% by weight to about 5% by weight. The invention also provides a method for disinfection of a substrate utilizing the composition. The composition of the invention may be used in the foregoing method on a medical instrument, such as an endoscope or the like. Applying the compositions to a substrate may be accomplished in any of a variety of application methods such as by roll coating, dipping, spraying, or rotational tumbling. The composition may be applied to the substrate for a period of time ranging from about 30 seconds to about ten minutes. In this aspect, the invention can further comprise drying the substrate after removing the composition.
