Foam soaps are aerosolized liquid soaps dispensed through a special pump mechanism. Currently there are no studies comparing liquid soap with foam soap in regard to efficacy of reducing hand microbial burden. In 3 separate experiments and with 2 different brands of foam soap, it was observed that nonantimicrobial foam soap was not as effective in reducing hand bacterial load as the liquid soap.
Hand hygiene has been shown to prevent the spread of infectious microorganisms, including those that are resistant to antimicrobial agents, in multiple settings, including hospitals.1 There have been multiple studies on the effectiveness of various types of cleansers, including plain soap, alcohol-based handrubs, and antibacterial soaps.2 There have been concerns over antibacterial soaps and emergence of resistant bacteria,3 and the US Food and Drug Administration has recently issued a final rule that banned over-the-counter consumer antiseptic wash products containing triclosan and triclocarban to be marketed.
