Enhanced activity alcohol-based antimicrobial compositions
First Claim
1. A composition having antimicrobial properties, comprising:
- an aliphatic alcohol having from 1 to about 8 carbon atoms in an amount from about 30 to about 90 parts;
an aromatic alcohol in an amount from about 0.5 to about 5.0 parts, wherein the hydroxyl group of the aromatic alcohol is connected to a non-aromatic ring carbon atom;
a cationic substrate binding activity enhancing substance in an amount from about 0.0125 to about 0.5 part; and
water in an amount from about 5 to about 65 parts, all said parts based on 100 parts by weight of the composition, said composition free of a cationic cellulose polymer.

Abstract
Antimicrobial compositions which can be used wherever disinfecting compositions are needed, such as in a hospital, healthcare industry, workplace, recreational facility, home or similar environment. The antimicrobial compositions are particularly useful as a topical application for a substrate, such as skin and can be used as a hand sanitizer or pre-surgical scrub. The compositions comprise a synergistic combination of a simple aliphatic alcohol and an activity enhancing substance, wherein the composition provides, heretofore unexpected, persistent activity against a broad range of microorganisms, including gram-negative organisms, while moisturizing the skin.

46. A method for forming an antimicrobial composition, comprising the steps of:
-
providing from 33 to about 65 parts of water to a vessel;
adding a cationic substrate binding activity enhancing substance to the vessel in an amount from about 0.0125 to about 0.5 part, wherein the cationic substrate binding activity enhancing substance is behenoyl PG-trimonium chloride, behenoyl PG-dimonium chloride, behenamidopropyl PG-dimonium chloride, or a combination thereof;
adding an aromatic alcohol to the vessel in an amount from about 0.5 to about 5.0 parts, wherein the hydroxyl group of the aromatic alcohol is connected to a non-aromatic ring carbon atom;
adding an aliphatic alcohol having from 1 to about 8 carbon atoms to the vessel in an amount from about 30 to about 58 parts;
adding a non-ionic thickener to the vessel; and
mixing the composition in the vessel, wherein the parts are based on 100 parts by weight of the composition, and wherein the composition is free of a cationic thickener. - View Dependent Claims (47, 48, 49, 50)
