Antimicrobial Hand Soap Composition

An aqueous liquid composition for application to the epidermis which provides a germicidal benefit thereto comprising:

• 0.02-10% wt. of a germicidally effective amount of a quaternary ammonium surfactant compound, which simultaneously functions as a source of cations and also to impart a germicidal benefit to the epidermis upon which the liquid composition is applied;
• 0.1-25% wt. of at least one anionic surfactant constituent that excludes anionic surfactants of the sulfate and sulfonate types, which one or more of the anionic surfactant constituents simultaneously provide a cleaning benefit and also function as a source of anions;
• 0.1-15% wt. of a cationic conditioner constituent, which simultaneously functions as an additional source of cations;
• 0-10% wt. of a foam stabilizer constituent;
• and
• at least 70% wt. of water;
• wherein the weight ratio of the germicidally effective amount of quaternary ammonium surfactant compound and the cationic conditioner constituent to the at least one anionic surfactant constituent is not less than 0.6;
• wherein the weight ratio of the germicidally effective amount of quaternary ammonium surfactant compound to the cationic conditioner constituent is less than 0.14;
• wherein the weight ratio of the cationic conditioner constituent to the at least one anionic surfactant constituent is at least 0.5;
• and
• wherein the pH of the liquid composition is between about 3.5 and about 7.5.

• and
• at least 70% wt. of water;
• wherein the weight ratio of the germicidally effective amount of quaternary ammonium surfactant compound and the cationic conditioner constituent to the at least one anionic surfactant constituent is at least 3;
• wherein the weight ratio of the germicidally effective amount of quaternary ammonium surfactant compound to the cationic conditioner constituent is less than 0.14;
• wherein the weight ratio of the cationic conditioner constituent to the at least one anionic surfactant constituent is at least 2;
• and
• wherein the pH of the liquid composition is between about 3.5 and about 7.5.
