Abstract

The present invention relates to a rinse-off antimicrobial cleansing composition comprising from about 0.1% to about 5% of an antimicrobial active, from about 8% to about 18% of an anionic surfactant, from about 2% to about 12% of a proton donating agent; from about 1% to about 30% of a lipophilic skin moisturizing agent; from about 0.1% to about 4% of a stabilizer; and from about 35% to about 88.8% of water. At least about 67% of the anionic surfactant comprises a mixture of Class A and Class C surfactant. The weight ratio of Class A surfactant to Class C surfactant ranges from about 5:1 to about 1:2. The composition is adjusted to a pH of from about 3.5 to about 4.5.
