Abstract
A rapidly acting antimicrobial alcohol-containing composition and method of using the composition to disinfect surfaces, such as the hands is disclosed.
Claims20
An antimicrobial composition comprising:
- a) from about 55 to about 90 percent by volume alcohol;
- b) an effective amount of an antimicrobial material selected from the group consisting of phenoxy ethanol, benzalkonium chloride, benzethonium chloride, cocophosphatidyl-dimonium chloride and mixtures thereof;
- c) a thickener consisting of from about 0.4 to about 0.7 weight percent of a carbomer polymer which is a copolymer having a major portion comprising a monoolefinically unsaturated carboxylic acid monomer or its anhydride of 3 to 6 carbon atoms;
- and a minor portion of a long chain acrylate or methacrylate ester monomer;
- said antimicrobial composition having a viscosity of from about 9,000 to about 22,000 centipoise as measured at 25.degree. C.
