In this study, we analyzed 1,4-dioxane in personal cleaning and hair products, which may have been contaminated during the cosmetic manufacturing process, using a gas chromatograph mass spectrometer with a headspace connected. A total of 125 samples, including 85 for personal cleaning, 37 for hair care, and 3 for children, were collected from large discount stores in Seoul and experimented for evaluation of 1,4-dioxane contents. In 58 of the 125 products, 1,4-dioxane was detected at levels of 0.58∼11.32 μg/g and the detection rate was 46.4%. 1,4-Dioxane was detected in 37 samples of body cleansers, 18 shampoos, and 3 liquid soaps. The highest observed level of 1,4-dioxane was 11.32 g/g in a body cleanser sample. The limit of detection(LOD) and limit of quantitation(LOQ) were 0.045 μg/g and, 0.135 μg/g, respectively, and the recovery rate was 102.5∼106.1% in body cleanser samples.
