Analysis of 1,4-Dioxane in Consumer Products by Headspace-Gas Chromatography/Mass Spectrometry
1,4-Dioxane is an industrial chemical contaminate that may be found at trace levels in consumer products. Government jurisdictions are beginning to regulate the amount of 1,4-dioxane allowed in consumer products. The allowable concentrations are expected to vary from state to state and country to country. Meanwhile, it has already been banned and deemed unsafe in cosmetics in Canada. There have been several methods developed to test for 1,4-dioxane, but none of these methods are adequate to detect 1,4-dioxane in consumer products with complex mixtures and solutions.
This study shows methodology for low level detection of 1,4-dioxane in consumer products including cosmetics, liquid soaps, shampoos, and cleaning products. The analysis was performed on an Agilent 7697A headspace sampler attached to an Agilent Intuvo 9000 GC with a 5977B MSD using MassHunter software and a PAL-3 Robotic Autosampler (SPME tool) attached to an Agilent 8890 GC with an Agilent 7000 MSD using Agilent Mass Hunter software
