Abstract

AbstractA method has been developed for the rapid and direct analysis of bacteriostats (3,4,4′‐trichlorocarbanilide and 2,4,4′‐trichIoro‐2′ ‐hydroxydiphenyl ether) in soaps with the aid of reverse phase high pressure liquid chromatography (HPLC) The bacteriostats were conveniently analyzed by UV absorption detection at 280 nm. A typical analysis of bacteriostats by this method requires 15 min for sample preparation and 15 min for the HPLC run. As the system needs no equilibration time (isocratic elution), it is immediately and reproducibility.
