4.6. Sterility of Ink, Packaging and During Tattooing
Tattooing and the application of PMU – including treatment and maintenance of the instruments, in particular their sterilisation and disinfection – must be carried out in accordance with the CEN TC 435 standard “Tattooing Services —Safe practice and hygiene requirements”.
Tattoo inks have to be sterile and supplied in a container which maintains the sterility of the product until application, preferably in a packaging size appropriate for single use. In case multi-use containers are used, their design should ensure that the contents will not be contaminated during the period of use. The sterility of the ink is tested by harmonised methods [?].
