This report addresses the issue of the safety of tattoo/PMU products and practices with a view to contribute to consumers' health protection. It has been prepared on behalf of the Directorate General Justice and Consumers (DG JUST), however it might also be of interest to other stakeholders dealing with health, internal market and environment, as well as to the European Chemicals Agency (ECHA). The conclusions of this project aim to provide the European Commission (EC) with the scientific evidences needed to decide if European Union (EU) measures are necessary to ensure the safety of tattoo/PMU inks and processes. In fact, apart from the general safety requirements by the General Product Safety Directive (GPSD) currently there is no specific EU legislation on tattoos/PMU products. In particular with regards to chemical requirements, there are chemicals which are banned in consumer products that get into direct contact with the skin under different EU legislations, like the Cosmetic Product Regulation or REACH, but not in tattoo inks. The report presents an updated review of the national legislative framework, ink ingredients in use and reported adverse health effects, as well as new data on analytical methods, statistics, market surveillance and RAPEX (Rapid alert system for non-food dangerous products) notifications, risk perception and communication and experience with the implementation of the Council of Europe (CoE) Resolutions (ResAP).
