Exclusive use of an antibacterial bar soap (refined and milled), containing 2% of a mixture of 3,5 dibromosalicylanilide and 3,4′,5 tribromosalicylanilide, 3,4,4′ trichlorocarbanilide, and 4,4′ dichloro-3-(trifluoromethyl) carbanilide, during a two-month period decreased the incidence of superficial cutaneous infections 44%. Comparison was made with a control group using an identical soap bar minus the antibacterial ingredients. Subjects were cadets taking part in the midsummer period of orientation required of each entering class at the United States Military Academy. No instances of adverse skin reactions were noted in any of the individuals exposed to the antibacterial bar soap.
