Allergic contact dermatitis (ACD) often associated with the topical use of perfumed products, remains one of the most common chronic skin disorders in Western countries. Since labelling of scented menstrual hygiene products (MHPs) is not mandatory, women might be unknowingly exposed to allergens. Given that vaginal mucosae lack the vital barrier function of the skin, skin allergens can easily penetrate and become systemically available and hence women may experience adverse effects in the anogenital region. The aim of this study was therefore to investigate whether women using scented MHPs are at risk of sensitization and hence developing ACD. Hereto, a Quantitative Risk Assessment (QRA) is performed on four well-known skin sensitizing chemicals (α-isomethyl ionone, benzyl salicylate, hexyl cinnamaldehyde and heliotropine) that were previously found leaching from five different scented MHPs including tampons and sanitary pads. The amounts of heliotropine, leached by one of the investigated tampons, exceeded acceptable exposure levels determined with the QRA and could induce sensitization. In addition, although no sensitization is expected for the other three compounds, an allergenic reaction might be provoked in women who are already sensitized. Labelling of allergens on scented MHPs would therefore help consumers to prevent adverse effects linked to ACD.
