1. An antimicrobial cleansing composition comprising:
- an effective amount of a salt of chlorhexidine for providing antimicrobial activity to the cleansing composition;
an amount of at least one alkyl polyglucoside effective for not substantially reducing the antimicrobial activity of said salt of chlorhexidine; and
an amphoteric surfactant selected from the group consisting of an alkyl phosphatidyl propylene glycol-dimonium chloride and an alkylammino carboxylate wherein in the alkyl group is 8 to 18 carbon atom in an amount effective for providing foaming properties;
said composition being devoid of any polyoxypropylene/polyoxyethylene block copolymers, any lower alkanols, and any alcohol diluents, and wherein said composition exhibits at least about a log 3 reduction against a bacteria selected from the group consisting of Staphylococcus aureus (ATCC #33591), Enterococcus faecium (ATCC #19434), Serratia marcescens (ATCC
14756), Escherichia coli (ATCC
8739), Pseudomonas aeruginosa (ATCC
15442) in a 30 second exposure kill test.

Abstract
A cleansing composition includes a salt of chlorhexidine such as chlorhexidine digluconate and at least one nonionic surfactant which does not include any polyoxypropylene/polyoxyethylene block copolymers. Also included in the composition is at least one amphoteric surfactant. Other additives such as viscosifiers or thickeners, emollients, fragrances, perfumes, coloring agents, preservatives, foaming agents, fungicides and the like may also be added. Preferably, the composition does not include alcohol as a carrier. The cleansing composition has been found to exhibit improved antibacterial properties while remaining mild on the skin.
