Quantifying 1,4-Dioxane in Personal Care, Cosmetic and Cleaning Products

1,4-Dioxane is an emerging industrial chemical of concern and probable human carcinogen found as a contaminate in personal care, cosmetic and cleaning products. To curb the release of the compound into the environment, new regulatory limits on the concentration of 1,4-dioxane in these products are proposed by state governments.Thus, the need for new analytical methods for testing these products is critical.

Two methods will be described for the analysis of 1,4-dioxane in consumer product matrices including hand soaps, shampoos, and laundry detergents. The methods will include review of a headspace GC/MS workflow and a solid-phase microextraction GC/QQQ workflow. Method performance criteria for both workflows will be presented to ensure quality assurance and quality control requirements are met.
