BACKGROUND: According to the REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) restriction, tattoo and permanent make-up (PMU) inks placed on the European Union market after January 4, 2022, shall not contain methylisothiazolinone, benzisothiazolinone (BIT), octylisothiazolinone (OIT), or other skin sensitizers in concentrations of 10 mg/kg or higher and phenoxyethanol (PE) or other eye irritants or damaging substances in concentrations of 100 mg/kg or higher. In addition, preservatives and other substances enlisted in Annex II to Cosmetic Product Regulation shall not be present in concentrations of 0.5 mg/kg or higher.
OBJECTIVES: This study aims to quantify 14 preservatives in 99 tattoo and 39 PMU inks from the Italian market and presents a comparison with concentration limits set by the REACH restriction.
METHODS: Inks were analysed by applying validated analytical methods based on liquid chromatography techniques.
RESULTS: About 24.0%, 15.2% and 1.5% of the overall samples contained BIT, PE and OIT, respectively, at concentrations exceeding REACH concentration limits. The number of noncompliant tattoo inks (49.5%) would be significantly greater than that of the PMU inks (17.9%).
CONCLUSIONS: About 40.6% of the samples would be noncompliant with the restriction for the presence of preservatives above the permitted level. Additional concentration limits will apply to skin sensitizing preservatives for proper labelling of inks under CLP (Classification, Labelling and Packaging) Regulation.
