“…Regarding banned dyes, the majority of studies are focused on the determination of Rhodamine B. Given its genotoxic effects, many methods have been exclusively developed for the analysis of this compound [9,25,27,28,36,38,39], and it will be commented on separately. With the exception of these cases, the current trend is the development of methods for the simultaneous analysis of mixtures of colorants: up to 32 for qualitative analysis [32] or 19 for quantitative analysis [26].…”

“…Concerning cosmetics, there have been several methods reported in the last 10 years that combine LC and DAD for the quantitative [28,[30][31][32] and qualitative [32] analysis of multiple dyes or that apply direct spectrophotometric measurement when only one dye is considered [9,25,27,35,39] (see Table 4). In these latter methods, good limits of detection were obtained because of the concentration achieved using an extraction technique such as SPE, CPE or DLLME previous to the analysis.…”

“…Rhodamine B was identified and quantified in two lipsticks at concentrations of 39 and 127 µg·g −1 . Recently, Bişgin et al [25] developed two extraction methods based on SPE and CPE (cloud point extraction) for the determination of Rhodamine B in lipstick as well. In both cases, sample was previously dissolved in 25 mL of CCl 4 , which is potentially a long-term carcinogenic solvent.…”

Analysis of Dyes in Cosmetics: Challenges and Recent Developments

Colour plays a decisive role in the marketing of a cosmetic product. Among thousands of substances used to colour, synthetic dyes are the most widespread in the industry. Their potential secondary effects on human health and different regulatory requirements for their use between the main world markets make analytical control necessary to guarantee the safety of a cosmetic product. However, methodologies for the determination of dyes in cosmetics are scarce with respect to those reported for other cosmetic ingredients such as preservatives or ultraviolet UV filters. In addition, most of the existing methods just consider a part of the total of dyes regulated. On the other hand, many methods have been developed for matrices different than cosmetics such as foodstuff, beverages or wastewater. The current paper reviews the recent developments in analytical methodologies for the control of synthetic dyes in cosmetics proposed in the international scientific literature in the last 10 years (2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017)(2018). A trend towards the use of miniaturized extraction techniques is evidenced. Due to the hydrophilic nature of dyes, liquid chromatography is the most usual choice in combination with absorbance detectors and, more recently, with mass spectrometry.

“…In the view of their importance, applications and related health issues, these dyes were quantitatively determined using different analytical instruments. Spectrophotometry, a widely used method for analyses of dyes, has been utilized in the analysis of MB [ 15 , 16 , 17 ], RB [ 18 , 19 , 20 ] and CV [ 21 , 22 ], although in different matrices. Electrochemical analysis has also been conducted on MB, CV and RB [ 23 , 24 , 25 ].…”

Development of Ultra-Performance Liquid Chromatography–Mass Spectrometry Method for Simultaneous Determination of Three Cationic Dyes in Environmental Samples

et al. 2020

Lower dye concentrations and the presence of several dyes along with other matrices in environmental samples restrict their determination. Herein, a highly sensitive and rapid ultra-performance tandem mass spectrometric method was developed for simultaneous determination of cationic dyes, namely methylene blue (MB), rhodamine B (RB) and crystal violet (CV), in environmental samples. To preconcentrate environmental samples, solid-phase extraction cartridges were developed by using hydrogen peroxide modified pistachio shell biomass (MPSB). The surface morphological and chemical functionalities of MPSB were well characterized. The developed method was validated considering different validation parameters. In terms of accuracy and precision, the %RSD for all three dyes at all four concentration points was found to be between 1.26 and 2.76, while the accuracy reported in terms of the recovery was found to be 98.02%-101.70%. The recovery was found to be in the range of 98.11% to 99.55%. The real sample analysis shows that MB, RB, and CV were found in the ranges of 0.39–5.56, 0.32–1.92 and 0.27–4.36 μg/mL, respectively.
