Abstract
This invention relates to an antimicrobial sanitizing composition in the form of a gel or cream that contains an alcohol in an amount of at least 55% by weight. The sanitizer is capable of disinfecting and providing prolonged antimicrobial property to a variety of surfaces, including the skin, without causing, drying, cracking, redness or irritation. 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. The anionic phospholipid enables use of the composition without the user experiencing dryness or irritation and the feeling of a greasy and unpleasant residue on the skin following use.
