Abstract
鉴于当前化妆品中二甲基环硅氧烷的添加乱象,以及关于二甲基环硅氧烷在化妆品中安全风险评价的研究也未有实质性进展,因此建立适合不同配方体系化妆品中二甲基环硅氧烷的测定方法具有一定的理论和现实意义。基于此,建立了凝胶渗透色谱净化结合气相色谱-串联质谱测定不同配方体系化妆品中7种二甲基环硅氧烷的方法。方法采用乙酸乙酯-环己烷(1∶1, v/v)提取,凝胶渗透色谱净化,通过DB-5ms色谱柱(30.0 m×0.25 mm×0.25 μm)分离和气相色谱-串联质谱选择反应监测(SRM)模式进行确证和检测,以正十六烷为内标物内标法定量。分别对内标物、提取溶剂和净化方式的选择进行了优化。在最终确立的条件下,7种二甲基环硅氧烷在0.05~1.0 mg/L范围内线性良好,相关系数为0.994~0.998;方法的检出限(LOD, S/N=3)和定量限(LOQ, S/N=10)分别为0.04~0.08 mg/kg和0.12~0.24 mg/kg;针对不同配方体系的化妆品基质,进行了低、中、高3个添加水平的加标回收试验,目标物的加标回收率为85.3%~108.8%,相对标准偏差(RSD)为3.1%~9.4%。该方法操作简便,灵敏度高,重复性好,能够满足不同配方体系化妆品中7种二甲基环硅氧烷的测定要求。采用所建立的方法对市面上的化妆品进行检测,八甲基环四硅氧烷(D4)和十甲基环五硅氧烷(D5)均有不同程度的检出。该方法的建立将为我国化妆品中二甲基环硅氧烷的质量监督检查提供技术依据,有利于保障化妆品的安全,同时也为后续化妆品中二甲基环硅氧烷的健康安全风险评价提供了技术支撑。

Abstract
A rapid method for determination of parabens preservatives (methyl paraben, ethyl paraben, isopropyl paraben, propyl paraben, isobutyl paraben, and butyl paraben) in flavors was established by using supercritical fluid chromatography tandem mass spectrometry combined with dispersive solid phase extraction. After adding methanol and primary secondary amine to the sample simultaneously, high extraction efficiency and good sample cleanup could be obtained by simple shaking. Parabens were well separated on a Chiralpak IG-3 column in 6 min by gradient elution. Recoveries from spiked blank samples at 0.5, 1.0, and 5.0 mg/kg were determined to be 88.3-106.6%with relative standard deviations less than 8.0%. All analytes achieved good linear relation (r≥0.999 2). The limits of detection for all analytes ranged from 0.03 to 0.09 mg/kg and the limits of quantification from 0.11 to 0.31 mg/kg, respectively. A total of 20 actual samples were successfully analyzed by taking the proposed method. Being simple, rapid, green and reliable, this method can be taken for the determination of parabens preservatives in flavors. This article is protected by copyright. All rights reserved.

Abstract
The wide range and complexity of cosmetic formulations currently available on the market poses a challenge from an analytical point of view. In addition, during cosmetics manufacture, impurities coming from raw materials or formed by reaction of different organic compounds present in the formulation may be present. Their identification is mandatory to assure product quality and consumer health. In this work, micro-matrix solid-phase dispersion (μMSPD) is proposed as a multi-target sample preparation strategy to analyze a wide number of unexpected families of compounds including polycyclic aromatic hydrocarbons (PAHs), pesticides, plasticizers, nitrosamines, alkylphenols (APs), and alkylphenol ethoxylates (APEOs). Analytical determination was performed by gas chromatography-mass spectrometry (GC-MS) for the determination of 51 target compounds in a single run, whereas liquid chromatography tandem mass spectrometry (LC-MS/MS) was employed for the analysis of six APs and APEOs. Both methodologies were successfully validated in terms of linearity, accuracy, and precision in leave-on and rinse-off cosmetics. Limits of detection (LODs) were calculated in the low ng g−1, showing their suitability to determine trace levels of impurities and banned compounds with different chemical natures, providing useful tools to cosmetic control laboratories and companies.

Abstract
In this work, a deep eutectic solvent (DES) composed of tetrabutylammonium bromide (TBABr) and acetic acid in a 1:2 M ratio was applied as the dispersive solvent for the dispersive liquid-liquid microextraction based on solidification of floating organic droplet (DLLME-SFO), using 1-decanol as extractant. Six preservatives (benzoic acid, BA; sorbic acid, SA; methyl paraben, MP; ethyl paraben, EP; propyl paraben PP; and butyl paraben, BP) in beverages were determined simultaneously through high-performance liquid chromatography with a diode array detector (HPLC-DAD). Under the optimal experimental condition that consists of 200 μL of disperser (TBABr: acetic acid, 1:2), 80 μL of extractant (1-decanol), 3 min of vortex time, 4.5 of pH, 2.5 g of NaCl, the proposed method showed satisfactory linearity in the range of 0.05-50.0 mg L-1, with a correlation coefficient (R2) higher than 0.9998. The limits of detection (LODs) varied from 0.02 to 0.05 mg L-1 and the limits of quantification (LOQs) varied from 0.05-0.1 mg L-1. The relative standard deviations (intra-day and inter-days) were below 5 %. The developed method was successfully applied to the determination of preservatives in beverages.

A simple headspace gas chromatography/mass spectrometry method for the quantitative determination of the release of the antioxidants butylated hydroxyanisole and butylated hydroxytoluene from chewing gum. RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2017; 31:859-864.

Abstract
RATIONALE Butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) are widely used to prevent oxidation and rancidity in foodstuffs, pharmaceutical preparations and cosmetic formulations. Although their safety has been thoroughly investigated, possible endocrine side-effects have been suggested. A useful method for the determination of BHA and BHT in foods is needed to estimate their daily intake through the diet. METHODS We selected commercial chewing gums as a model of a complex food matrix and developed a new method based on gas chromatography/mass spectrometry. This allows the determination of 130 pg/gum of BHA and 9 pg/gum of BHT. RESULTS Analysis of different chewing gums from the European market indicated that the two antioxidants were never used together and that the content of BHA was in the range of 220-348 μg/gum and BHT ranged from 278 up to 479 μg/gum. These amounts correspond to 86-157 mg/kg gum for BHA and 170-185 mg/kg gum for BHT, and are both within the maximum levels established by the European Food Safety Authority. Chewing a piece of gum for 15 min resulted in the release of up to 28% of BHA, but no release of BHT was detectable. CONCLUSIONS A new, simple and rapid method for the determination of BHA and BHT in chewing gums was described. This analytical method, based on headspace sampling, did not require the extraction of antioxidants from chewing gum samples, assuring the absence of any gum material contaminants that might affect the instrumentation. It is also automatable, employing a sequential automatic sampler. This method could be of interest to academic researchers and to food industrialists looking for a new methodological approach for BHA and BHT determination in foodstuffs with complex matrices.

Abstract
Cosmetic products placed on the market and their ingredients, must be safe under reasonable conditions of use, in accordance to the current legislation. Therefore, regulated and allowed chemical substances must meet the regulatory criteria to be used as ingredients in cosmetics and personal care products, and adequate analytical methodology is needed to evaluate the degree of compliance. This article reviews the most recent methods (2005-2015) used for the extraction and the analytical determination of the ingredients included in the positive lists of the European Regulation of Cosmetic Products (EC 1223/2009): comprising colorants, preservatives and UV filters. It summarizes the analytical properties of the most relevant analytical methods along with the possibilities of fulfilment of the current regulatory issues. The cosmetic legislation is frequently being updated; consequently, the analytical methodology must be constantly revised and improved to meet safety requirements. The article highlights the most important advances in analytical methodology for cosmetics control, both in relation to the sample pretreatment and extraction and the different instrumental approaches developed to solve this challenge. Cosmetics are complex samples, and most of them require a sample pretreatment before analysis. In the last times, the research conducted covering this aspect, tended to the use of green extraction and microextraction techniques. Analytical methods were generally based on liquid chromatography with UV detection, and gas and liquid chromatographic techniques hyphenated with single or tandem mass spectrometry; but some interesting proposals based on electrophoresis have also been reported, together with some electroanalytical approaches. Regarding the number of ingredients considered for analytical control, single analyte methods have been proposed, although the most useful ones in the real life cosmetic analysis are the multianalyte approaches.

Abstract
A powerful and efficient signal-preprocessing technique that combines local and multiscale properties of the wavelet prism with the global filtering capability of orthogonal signal correction (OSC) is applied for pretreatment of spectroscopic data of parabens as model compounds after their preconcentration by robust ionic liquid-based dispersive liquid-liquid microextraction method (IL-DLLME). In the proposed technique, a mixture of a water-immiscible ionic liquid (as extraction solvent) [Hmim][PF6] and disperser solvent is injected into an aqueous sample solution containing one of the IL's ions, NaPF6, as extraction solvent and common ion source. After preconcentration, the absorbance of the extracted compounds was measured in the wavelength range of 200-700 nm. The wavelet orthogonal signal correction with partial least squares (WOSC-PLS) method was then applied for simultaneous determination of each individual compound. Effective parameters, such as amount of IL, volume of the disperser solvent and amount of NaPF6, were inspected by central composite design to identify the most important parameters and their interactions. The effect of pH on the sensitivity and selectivity was studied according to the net analyte signal (NAS) for each component. Under optimum conditions, enrichment factors of the studied compounds were 75 for methyl paraben (MP) and 71 for propyl paraben (PP). Limits of detection for MP and PP were 4.2 and 4.8 ng mL(-)(1), respectively. The root mean square errors of prediction for MP and PP were 0.1046 and 0.1275 μg mL(-)(1), respectively. The practical applicability of the developed method was examined using hygienic, cosmetic, pharmaceutical and natural water samples.

Abstract
Cosmetic multidose preparations, as well as pharmaceutical ones, are at risk of contamination by microorganisms, due to their high water content. Besides the risk of contamination during manufacturing, multidose cosmetic preparations may be contaminated by consumers during their use. In this paper, the results of the utilization of nanoparticles as reservoir systems of parabens, the most used class of preservatives, were reported. Two different systems, solid lipid nanoparticles (SLN) made of pure precirol and nanostructured lipid carriers (NLC) made of precirol and almond oil, containing three parabens as single molecules or as a mixture, were prepared and tested. All the systems were characterized for size, polydispersion index, zeta potential and encapsulation efficiency. Release experiments, carried out in steady state and sink conditions, allowed to evidence that both SLN and NLC were able to act as reservoir systems. The antimicrobial activity of the systems was tested against Candida albicans ATCC 10231 with repeat insult tests. The results of the release experiments and the antimicrobial tests showed very low water concentration of parabens still maintaining their antimicrobial activity.

Abstract
Introduction: A novel and simple isocratic reverse phase liquid chromatographic (RP-LC) method was developed for the quantitative determination of antioxidant-butylated hydroxy toluene (BHT) in paricalcitol hard gelatin capsule. In the paricalcitol capsule BHT concentration is very low. This method is precisely able to estimate BHT at low concentration at about 0.0039 μg/mL and to separate BHT from paricalcitol main compound and other oil-based excipients. Materials and Methods: The method was developed by using ACE-C18 (250 × 4.6 mm) 5-μm column with mobile phase containing a mixture of solvent A (water) and solvent B (methanol) in the ratio of 5:95 v/v, respectively. The flow rate was 0.8 mL/min with column temperature of 45°C and detection wavelength at 277 nm. The developed method was validated as per ICH guidelines with respect to specificity, linearity, limit of detection, limit of quantification, accuracy, precision and robustness. Results: In the precision study the % RSD for the result of BHT was below 1.5% at target concentration level. The limit of detection, limit of quantification are 0.0013 μg/ mL and 0.0039 μg/mL, respectively and precision at LOQ level (0.0039 μg/mL) was with 6.2% RSD. The method was linear with concentration rage of 0.0039-0.64 μg/ mL with the correlation coefficient greater than 0.999 and % bias at 100% level are within + 2%. The percentage recoveries for BHT were calculated observed from 98.8 to 104.8%. Conclusion: The developed method was found to be precise, accurate, linear, selective and robust.

Abstract
An HPLC method with ultraviolet-visible spectrophotometry detection has been optimized and validated for the simultaneous determination of phenolic compounds, such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) as antioxidants, and octyl methyl cinnamate (OMC) as UVB-filter in several personal care products. The dynamic range was between 1 to 250 mg/L with relative standard deviation less than 0.25% (n = 4). Limits of detection for BHA, BHT, and OMC were 0.196, 0.170, and 0.478 mg/L, respectively. While limits of quantification for BHA, BHT, and OMC were 0.593, 0.515, and 1.448 mg/L, respectively. The recovery for BHA, BHT, and OMC was ranged from 92.1-105.9%, 83.2-108.9%, and 87.3-103.7%, respectively. The concentration ranges of BHA, BHT, and OMC in 12 commercial personal care samples were 0.13-4.85, 0.16-2.30, and 0.12-65.5 mg/g, respectively. The concentrations of phenolic compounds in these personal care samples were below than maximum allowable concentration in personal care formulation, that is, 0.0004-10 mg/g, 0.002-5 mg/g, and up to 100 mg/g for BHA, BHT, and OMC, respectively.

Abstract
A simple, fast, robust and reliable multicomponent analytical method applicable in control laboratories with a high throughput level has been developed to analyze commercial brands of perfumes. Contents of 52 cosmetic ingredients belonging to different chemical families can be determined in a single run. Instrumental linearity, precision of the method and recovery studies in real samples showed excellent results, so that quantification by external calibration can be effectively applied. Relevant limits of detection and quantification were obtained for all the targets considered, far below the legal requirements and amply adequate for its accurate analytical control. A survey of 70 commercial perfumes and colognes has been performed, in order to verify whether these products complied with the recent changes in European legislation: regarding the maxima allowed concentrations of the ingredients and/or ingredient labelling. All samples contained some of the target ingredients. Several samples do not comply with the regulations concerning the presence of phthalates. Musks data confirmed the trend about the replacement of nitromusks by polycyclic musks; as well as the noticeable introduction of macrocyclic musks in the perfumes composition. The prohibited musk moskene has been detected in one sample in an appreciable concentration. The average number of fragrance allergens is twelve per sample; their presence must be indicated in the list of ingredients when its concentration exceeds the 0.001%, but values higher than 1% have been found in some samples. Preservatives data show that parabens, although ubiquitous in other cosmetic products, are not widely used in perfumery. In contrast, the presence of BHT is indeed widespread. The degree of compliance with the European Regulation on the labelling has been evaluated in a subset of samples, and only about the 38% of the perfumes were properly labelled for the allergens tested.
