1. A method for sanitizing skin, the method comprising:
- applying a sanitizer to the skin in the form of a gel or a cream, the sanitizer having a pH of at least 6.8 and comprising;
at least 60 weight percent of a C1 to C4 alcohol;
a rheology modifier and optionally at least one emollient and/or at least one emulsifier, the rheology modifier being selected from the group consisting of carboxylic acid polymers, crosslinked polyacrylate polymers, polyacrylamide polymers, polysaccharides, and combinations thereof; and
an anionic phospholipid in an amount of at least 0.1 weight percent of the sanitizer.

Abstract
An antimicrobial sanitizing composition in the form of a gel or cream containing an alcohol in an amount of at least 55% by weight. The sanitizer is capable of disinfecting a variety of surfaces, including the skin. In addition to alcohol, the sanitizer contains an anionic phospholipid in a controlled concentration as well as components conventionally found in skin creams and gels such as emulsifiers, emollients, moisturizers, rheology modifiers, and neutralizers.

10. A method of forming a sanitizer composition, the method comprising:
forming a sanitizer in the form of a gel or a cream, the forming the sanitizer comprising; adding an anionic phospholipid to an alcohol to form a first mixture; heating the first mixture to a temperature of 30°
C. to form a first homogeneous solution;cooling the first homogeneous solution to room temperature; adding a water soluble moisturizer to water to form a second homogeneous solution; after the cooling, combining the first homogeneous solution, the second homogeneous solution, and a rheology modifier to form a second mixture, the rheology modifier being selected from the group consisting of carboxylic acid polymers, crosslinked polyacrylate polymers, polyacrylamide polymers, polysaccharides, and combinations thereof; and agitating the second mixture to form the sanitizer, the sanitizer having a pH of at least 6.8, the alcohol being present in an amount of at least 55 percent by weight of the sanitizer, and the anionic phospholipid being present in an amount of at least 0.10 percent by weight of the sanitizer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of forming a sanitizing composition, the method comprising:
forming a sanitizing composition, the forming the sanitizing composition comprising; mixing a phospholipid mixture, an emollient, an emulsifier, and one or more alcohols having from 1 to 4 carbon atoms to form a first mixture; heating the first mixture to 30°
C. to form a first homogeneous mixture;the phospholipid mixture comprising an anionic phospholipid; the emollient being selected from the group consisting of oils, aloe, fatty esters, glycerol esters, propylene glycol esters, alkoxylated carboxylic acids, alkoxylated alcohols, fatty alcohols, fatty acids, and combinations thereof; the emulsifier being selected from the group consisting of esters of glycerin, esters of propylene glycol, fatty acid esters of polyethylene glycol, fatty acid esters of polypropylene glycol, esters of sorbitol, esters of sorbitan anhydrides, carboxylic acid copolymers, esters and ethers of glucose, ethoxylated ethers, ethoxylated alcohols, alkyl phosphates, polyoxyethylene fatty ether phosphates, fatty acid amides, acyl lactylates, soaps, triethanolamine (TEA) stearate, diethanolamine (DEA) oleth-3 phosphate, polyethylene glycol 20 sorbitan monolaurate (polysorbate
