A rapid high‐resolution NMR method has been developed for the determination of soap and detergent bacteriostats. The method can be used to identify six common commercial bacteriostats (3,4,4′‐trichlorocarbanilide; 3‐trifluoromethyl‐4,4′‐dichlorocarbanilide; 4′,5‐dibromosalicylanildie; 3,5‐dibromosalicylanilide; 3,4′,5‐tribromosalicylanilide; and ehxachlorophene) and all two‐component mixtures prepared from them. This method can also be used to determine the relative concentrations of these bacteriostats in all two‐component mixtures. The precision and accuracy of the method are estimated to be within 3% absolute.
