The purpose of this study was to investigate present status of use about antimicrobial agent (triclosan, ethanol) and preservatives (sodium benzoate, methyl p-hydroxybenzoate, propyl p-hydroxybenzoate) in dentifrice. 75 samples including 16 mouthwashes were analyzed in this study. Contents of triclosan and preservatives were analyzed using by HPLC and ethanol was analyzed by headspace-GC. Preservatives were detected from total 37 samples, which are suitable for the legal limits in Korea. Methyl p-hydroxybenzoate was detected from 26 samples (0.003~0.19%), propyl p-hydroxybenzoate was detected from 11 samples (0.002~0.02%) and sodium benzoate was detected from 14 samples (0.1~0.3%), respectively. Methyl p-hydroxybenzoate was detected from 6 samples (0.03~0.19%), propyl p-hydroxybenzoate was detected from 1 samples (0.01%) and sodium benzoate was detected form 5 samples (0.1~0.2%) in 20 dentifrice for children. Triclosan was not detected from 75 samples. Ethanol was detected from 16 samples (4.9~21.9%) in 19 samples; among them three samples showed the higher contents (20.5~21.9%) but ethanol contents was not labeled in these samples.
