Foam Soaps Less Effective Than Liquid Soaps In Removing Bacteria, Study Shows

Foam soaps may be less effective than liquid soaps in killing bacteria, according to a pilot study published in the American Journal of Infection Control. Research authors Ozlem Equils at UCLA's School of Medicine and colleagues tested two popular brands of foam and liquid detergent-based soaps, with results showing the average bacterial colony counts of volunteers showed greater reduction after using liquid soaps than those who used foam soaps. Foam soaps are becoming popular, replacing liquid soaps in public places, including hospitals, nursing homes, and schools, as well as the food industry.
