“…Moreover, the peaks at 3000–2800 cm –1 are related to the C–H, CH 3 , and CH 2 stretching bands for choline chloride, ethylene glycol, and ethaline. As can be seen from Figure , the vibration patterns for ethylene glycol and ethaline are the same except for the peak at 935–955 cm –1 that shows the presence of ammonium in the ethaline structure …”

Saffron stigmas are considered as one of the main sources for crocin extraction. Crocins have many therapeutic properties and applications in different industries such as food and cosmetic in which their extraction and purification will be useful commercially and clinically. This work presents a study on the partitioning of crocin in aqueous two-phase systems (ATPSs) composed of water, deep eutectic solvents (DESs), and acetonitrile (ACN). Two DESs based on choline chloride as the hydrogen bond acceptor (HBA) and urea and ethylene glycol as hydrogen bond donors (HBDs) were synthesized and considered as phase-forming components. Also, the effects of the hydrogen bonding, HBD species, weight percentages of DES, weight percentages of ACN, and temperature were investigated to evaluate the phase-forming ability of the ATPSs and the partitioning of crocin in these systems. It turned out that the choline chloride–urea/ACN system provides higher partition coefficients and a higher extraction efficiency of crocin under optimum conditions (40 wt % of DES, 50 wt % of ACN, and 25 °C). Moreover, the conformation of crocin in the choline chloride–urea/ACN system was explored using a UV–visible spectrophotometer (UV–vis) and Fourier transform infrared spectrometer (FT-IR), and no change was observed during the process. In the end, the UNIFAC model was applied to estimate the equilibrium data of both systems, in which the experimental data of two studied ATPSs were well described.

“…The broad band at 3285 cm −1 in the FTIR spectrum of ChCl:EG is assigned to the stretching vibration of the –OH groups of ChCl:EG. 65–67 Remarkable differences can be observed in the FTIR spectra of the eutectogels of WPU and ChCl:EG. The band of >3000 cm −1 becomes very broad, probably due to the formation of hydrogen bonds between ChCl:EG and WPU.…”

Recent Advances in Sample Preparation for Cosmetics and Personal Care Products Analysis

The use of cosmetics and personal care products is increasing worldwide. Their high matrix complexity, together with the wide range of products currently marketed under different forms imply a challenge for their analysis, most of them requiring a sample pre-treatment step before analysis. Classical sample preparation methodologies involve large amounts of organic solvents as well as multiple steps resulting in large time consumption. Therefore, in recent years, the trends have been moved towards the development of simple, sustainable, and environmentally friendly methodologies in two ways: (i) the miniaturization of conventional procedures allowing a reduction in the consumption of solvents and reagents; and (ii) the development and application of sorbent- and liquid-based microextraction technologies to obtain a high analyte enrichment, avoiding or significantly reducing the use of organic solvents. This review provides an overview of analytical methodology during the last ten years, placing special emphasis on sample preparation to analyse cosmetics and personal care products. The use of liquid–liquid and solid–liquid extraction (LLE, SLE), ultrasound-assisted extraction (UAE), solid-phase extraction (SPE), pressurized liquid extraction (PLE), matrix solid-phase extraction (MSPD), and liquid- and sorbent-based microextraction techniques will be reviewed. The most recent advances and future trends including the development of new materials and green solvents will be also addressed.
