“…Due to the capability of dyes to absorb in the UV-Vis spectrum, DAD or UV-Vis detectors were traditionally the preferred detectors [28,[30][31][32]. In recent years, mass spectrometry has become a valuable choice [24,26,29,33,34], given its enhanced selectivity and sensitivity; it is particularly desired in the analysis of banned compounds. Mass spectrometry overcomes limitations of DAD such as overlapping of UV-Vis spectra among matrix ingredients.…”

“…Recently, Guerra et al have been working on improving the simultaneous analysis of a great number of chemically different dyes in a broad range of cosmetics, including rinse-off and leave-on products [24,26,29]. In 2015 [29], they introduced the matrix solid-phase dispersion (MSPD) for the first time in the analysis of dyes in cosmetics.…”

“…The combination of liquid chromatography and mass spectrometry in the analysis of dyes in cosmetics was reported for the first time by Xian et al [33] in 2013. Afterwards, Guerra et al developed several improved methods based on this analytical technique [24,26,29]. Most of the dyes used in cosmetics and so considered in this review are sodium or calcium salts which contain in their structures one or more ionized groups such as sulphonic groups.…”

“…In this respect, the mobile phase (ionic strength, pH, and composition) plays an important role. In some cases, a mobile phase without additives, composed by water and an organic modifier (acetonitrile or methanol), has been employed achieving good sensitivity and a fast analysis [29,33]. The use of UPLC allowed performing the analysis of 11 dyes in 4 min [33].…”

“…In 2015 [29], they introduced the matrix solid-phase dispersion (MSPD) for the first time in the analysis of dyes in cosmetics. MSPD is a valuable approach for solid and semisolid samples for its simplicity and the possibility of performing a clean-up step simultaneously.…”

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.

Sample preparation techniques have experienced an explosive development during the past decades. Procedural approaches that use minimal sample amounts reducing to the limit and sometimes eliminating completely the use of toxic and/or environmentally unfriendly solvents and reagents have emerged as standard in the analytical laboratory. At the same time, significant improvements in sensitivity and selectivity have appeared. This article revised the principal developments of sample preparation methods for analytical determinations as produced recently. The approach is systematic, classifying the procedures into two broad groups: methods based on equilibrium and exhaustive methods. In each case, the principal methods are revisited with a brief description about the principles and chemistry involved and some significant examples. A large number of bibliographic references allow a deeper study on each case, when necessary.
