Fast-acting antimicrobial lotion with enhanced efficacy

摘要

An antimicrobial lotion for topical use comprises an oil-in-water emulsion with a dispersant of emollient droplets in an oil phase and an antimicrobial agent in a water phase. The emollients moisturize the skin. Antimicrobial agents have a more rapid antimicrobial effect in an aqueous solution than in the oil phase. A combination of anionic and nonanionic surfactants stabilize the emulsion and maintain a cationic antimicrobial agent primarily in the water phase. The resulting lotion is gentle on the skin while providing more rapid antimicrobial effect than conventional lotions. With longer lasting antimicrobial agents, such as chlorhexidene, the lotion is rubbed into the skin and left on to continue moisturizing and killing microbes for up to 12 hours.
