Aims: This study investigates the composition of tattoo pigments to ensure their safe application in tattoo art, evaluating the viability of UV-Vis and FT-IR spectroscopy, coupled with chemometrics, for predicting pigment contents in tattoo inks. Background: Analyzing pigments in tattoo inks poses challenges in maintaining quality. This study addresses the difficulties by proposing the use of UV-Vis and FT-IR spectroscopy, along with chemometrics, as potential solutions for effective monitoring. Objective: The aim of this study was to determine the content of red (PR) 170/254 and pigment blue (PB) 15:3 in tattoo inks from diverse suppliers and examine the distinct chemical structures and existing impurities in the samples using UV-Vis and FT-IR spectroscopy, employing regression models for data analysis. Method: We collected UV-Vis and FT-IR spectra from the tattoo ink samples and utilized regression models for data analysis. We assessed correlations across spectrum areas, emphasizing coefficients of determination for cross-validation. Subsequently, we compared the results obtained from both spectroscopic methods in terms of pigment identity and evaluated the suitability of UV-Vis spectroscopy for analyzing changes in pigment concentration and structural evolution. Finally, we employed chemometric modeling to enhance predictions of FT-IR parameters, particularly in the functional group and fingerprint region of the spectra. Results: Significant correlations were observed across both UV-Vis and FT-IR spectrum areas, with coefficients of determination for cross-validation exceeding 0.7 for most parameters. Both spectroscopic methods yielded nearly identical results regarding pigment identity. UV-Vis spectroscopy proved to be a suitable method for analyzing changes in pigment concentration and structural evolution. Chemometric modeling enhanced predictions of FT-IR parameters, particularly in the functional group and fingerprint region of the spectra. Conclusion: The study underscores the significance of utilizing ... |
