AbstractTwo antibacterial soaps and an antibacterial detergent were examined for their effectiveness in inhibiting the growth of a large number of bacteria. All products were markedly superior in this regard to a nonmedicated soap. A soap containing equal parts by weight of hexachlorophene and 3,4,4′‐trichlorocarbanilide was more effective than a detergent containing hexachlorophene only and a soap containing a mixture of equal parts by weight of 3,4′,5‐tribromosalicylanilide, 3,4,4′‐trichlorocarbanilide, and 4,4′‐dichloro‐3‐(trifluoromethyl) carbanilide. A total of 27 bacteria, including 12 pathogens, was used.
