The widespread applications of cosmetics in modern life make their analysis particularly important from a safety point of view. There is a wide variety of restricted ingredients and prohibited substances that primarily influence the safety of cosmetics. Sample preparation for cosmetic analysis is a crucial step as the complex matrices may seriously interfere with the determination of target analytes. In this review, some new developments (2010-2016) in sample preparation techniques for cosmetic analysis, including liquid-phase microextraction, solid-phase microextraction, matrix solid-phase dispersion, pressurized liquid extraction, cloud point extraction, ultrasound-assisted extraction, and microwave digestion, are presented. Furthermore, the research and progress in sample preparation techniques and their applications in the separation and purification of allowed ingredients and prohibited substances are reviewed.

“…These techniques are coupled with standard detection methods, most often ultraviolet (UV) detection [14][15][16][17][18], but chemiluminescent (CL) [23,24] and mass spectrometric (MS) detection [13,14,19,21,22] have also been reported. Capillary electrophoresis [1,25] has also been reported. However, all of these methods are time-consuming, and some require that the samples are concentrated prior to the experiment.…”

In this study, a new technique was developed using rapid ultra-performance liquid chromatography (UPLC)-based separation coupled with electrochemical detection by a boron-doped diamond (BDD) electrode for the detection and quantification of three commonly used parabens (methylparaben (MP), ethylparaben (EP) and propylparaben (PP)). We aimed to reduce the analysis time by using UPLC coupled with a short reverse phase C 18 monolithic column (25 mm × 4.6 mm). Operating the monolithic column at low back-pressure resulted in high flow rates. A mobile phaseconsisting of a 25:75 (v/v) ratio of acetonitrile: 0.05 M phosphate buffer (pH 5) at a flow rate of 2.5 mL•min −1 was used to perform the separation. The amperometric detection with the BDD electrode was found to be optimal and reliably reproducible at a detection potential of 1.5 V vs. Ag/AgCl. Under these conditions, the separation of the three targetanalytes (MP, EP and PP) was achieved in 2 min and was linear within a sample concentration range of 0.1 to 50.0 mg•L −1 (r 2 values of 0.9970, 0.9994 and 0.9994 for MP, EP and PP, respectively). This method was successfully applied to determine the concentrations of each parabeninsix real samples with therecoveries ranging from of 80.3%-98.9% for all three parabensfrom samples spiked at 12, 22 and 32 mg•L −1. Therefore, the proposed method can be used as an alternative rapid and selective method for the determination of paraben levels in real samples.

“…In recent years, different CE modes [15][16][17][18][19][20][21] and sample stacking strategies [21][22][23][24][25][26] have been used for this purpose. In addition, the use of poly(ethylene oxide) (PEO) solutions containing SDS and cetyltrimethylammonium bromide for the stacking and separation of biomolecules has also been demonstrated.…”

Simultaneous separation and quantification of seven parabens commonly used as preservatives in cosmetic products, by micellar electrokinetic chromatography with a stacking technique has been demonstrated. An effective on-line concentration strategy involving a combination of sweeping and the use of polymer solutions is a key feature of the proposed method, which successfully determined individual parabens. The analysis parameters such as injection time, pH and concentration of phosphate solution, and concentration of sodium dodecyl sulphate (SDS) and poly(ethylene oxide) (PEO) were examined. The optimum conditions were found to be as follows: a 15 mM phosphate solution (pH 9.5) containing 20 mM SDS for filling the capillary, and for the separation electrolytes, 0.100% PEO (8 MDa) added to the phosphate and SDS solution of the same composition as for the capillary. The entire analysis process was completed in 13 min and a 930-2200-fold enhancement factor was achieved. The LODs (S/N = 3) for this approach were in the range from 4.32 to 7.78 nM. The linear range for each paraben was between 50 nM and 5.0 mM (R 2 > 0.990). The optimized method was then successfully applied to the determination of parabens in commercial cosmetic products.
