A report released this week by the Swedish Chemicals Agency (KEMI) confirmed that the risk of negative effects on health from chemicals in menstrual products is low. The study determined and analysed the chemical substances in 35 different sanitary towels, tampons, panty liners and menstrual cups.

Part of the Swedish Government’s assignment to map hazardous chemical substances in products and articles that are available to the general public, the agency conducted a survey of hazardous chemical substances in feminine hygiene products. 

In the survey the agency conducted studies of literature and qualitative and quantitative chemical analyses of 35 different feminine hygiene products, studying what hazardous chemical substances the products contain and in what concentrations. A total of 62 chemical substances were analysed. Among these we found 21 hazardous chemical substances mainly in low concentrations and none of the substances are prohibited in these types of products. Reference to  "low concentrations" in this report mean concentrations of less than 0.1% by weight.
