Abstract

Topical aqueous liquid compositions for application to the epidermis which provide a germicidal benefit thereto comprising: 0.02-10% wt. of a germicidally effective amount of a quaternary ammonium surfactant compound, 0.1-25% wt. of at least one anionic surfactant constituent which excludes anionic surfactants of the sulfate and sulfonate types, 0.1-15% wt. of a cationic conditioner constituent, 0-10% wt. of a foam stabilizer constituent; at least 70% wt. of water, and optionally one or more of optional constituents which may be used to impart an aesthetic benefit, e.g., color, fragrance, or a further technical benefit, e.g., viscosity adjustment, to the liquid compositions, characterized in that: (a) the weight ratio of the germicidally effective quaternary ammonium and cationic conditioner constituent to the anionic surfactant constituent is not less than 0.6; and/or, (b) the weight ratio of the germicidally effective quaternary ammonium surfactant compound to the cationic conditioner constituent is less than 0.14; and/or, (c) the ratio of the cationic conditioner constituent to the anionic surfactant constituent is at least 0.5; and, (d) the pH of the liquid composition is between about 3.5 and about 7.5.
