The logic and cultural myths that buttress the cosmeceutical industry construct the older woman as a victim of old age, part of an “at-risk” population who must monitor, treat and prevent any markers of old age. A content and discourse analysis of 124 advertisements from the US More magazine between 1998 and 2008, revealed three major themes working together to produce this civic duty: (1) the inclusion of scientific and medical authorities in order to define the cosmeceutical as a ‘drug’ curing a disease, (2) descriptions of the similarities (and differences) between the abilities of cosmeceuticals and cosmetic surgery to restore one’s youth, and (3) the logic equating youth with beauty, femininity and power and older age with the absence of these qualities. Together these intersecting logics produce the “will to youth”—the imperative of the aging woman to promote her youthful appearance by any and all available means. Further, by using images and references to fantasies and traditional fairytales, cosmeceutical advertisements both promise and normalize expectations of eternal youth of the aging woman.

It is of technical and economic importance to develop an effective cosmetic ingredient against skin aging through low-cost and facile production. This study developed a polymer/layered silicate nanocomposite as cosmetic ingredient against skin aging. Firstly, quaternized carboxymethyl chitosan (QCMC)/organic montmorillonite (OMMT) nanocomposite (QCOM) was fabricated via solution-induced intercalation. QCOM with different mass ratios of QCMC to OMMT were studied by various characterizations as well as moisture-adsorption and retention activities and UV-protection capacity. QCOM was then added into a cosmetic formulation to prepare a cosmetic cream. And the evaluation of its efficacy about skin care was conducted. The results showed that the optimal QCOM had better moisture-adsorption and retention behaviors than hyaluronic acid, and QCOM solution displayed good UV-protection ability. Furthermore, the QCOM-containing cosmetic cream meets the hygienic standard for cosmetics; it has negligible dermal irritation and a prominent moisture-retention efficacy on human stratum corneum.

Synopsis en This link goes to a English section fr This link goes to a French section Objective To understand formaldehyde residue in cosmetics, an investigation on formaldehyde release from eight preservatives (methenamine – MA, paraformaldehyde – PF, poly(p-toluenesulfonamide-co-formaldehyde) -PTSAF, quaternium-15 – QU, imidazolidinyl urea – IU, diazolidinyl urea – DU, dimethyloldimethyl hydantoin – DMDM and bronopol – BP) under various conditions was performed. Methods The concentration of released formaldehyde was determined by high-performance liquid chromatography with photodiode array detection after derivatization with 2,4-dinitrophenylhydrazine. Results The amounts of formaldehyde release were in the order of PF > DU > DMDM ≈ QU ≈ IU > MA > BP > PTSAF. The releasing amounts of formaldehyde were the highest in the presence of aqueous matrices for the releasers except QU and IU, and the releasing effect was also relative to pH. More formaldehyde was released with longer storage time and higher temperature. Furthermore, all preservatives in cosmetic matrices released fewer amounts of formaldehyde than in pure aqueous or organic matrices, and the formaldehyde-releasing amounts were also cosmetic specific. Conclusion Formaldehyde release was dependent on the matrix, pH, time and mainly temperature, and the releasing effect was also cosmetic specific.

Methodes La concentration de formaldéhyde libéré a été déterminée par Chromatographie liquide à haute performance avec détection à réseau de photodiodes après dérivatisation avec du 2,4-dinitrophénylhydrazine. Résultats Les taux de dégagement de formaldéhyde étaient dans l'ordre décroissant PF> DU> DMDM ≈ UI> MA ≈ QU> BP> PTSAF. Les taux de libération de formaldéhyde étaient les plus élevés en présence de matrices aqueuses pour les libérateurs sauf QU et IU et l'effet de libération était également variables selon le pH. Plus de formaldéhyde a été libéré plus la durée du temps de stockage et la température étaient élevées. En outre, tous les conservateurs dans les matrices cosmétiques libéraient moins de quantités de formaldéhyde que dans les matrices aqueuses ou organiques purs et les taux de libération de formaldéhyde étaient également spécifique pour chaque cosmétique. Conclusion Le dégagement de formaldéhyde était dépendant de la matrice, du pH, du temps de stockage et surtout de la température et l'effet de libération était aussi spécifique de la formulation cosmétique

Gold nanomaterials (Au NMs) have been widely used in cosmetic products for improving the brightening, and reducing the wrinkling of, skin, etc.; however, the dermal safety of Au NMs is rarely concerned. A previous study found that cosmetics could enhance the toxicity of Au nanosheets, but different physicochemical properties of Au NMs will induce different interaction modes with ingredients of cosmetics, potentially leading to different toxicity profiles. In the present study, spherical and rodlike Au NMs were first found in commercial cosmetics, and then Au nanospheres (NSs) with different sizes and Au nanorods (NRs) with different aspect ratios were prepared to simulate these Au NMs in cosmetics and further investigate their toxicity before and after embedment in cosmetics. It was found that the primary sizes, morphologies, and optical absorptions of these Au NSs and NRs before and after embedment were similar; however, their hydrodynamic sizes and zeta potentials were noticeably different. Then, these Au NSs and NRs presented weak or no cytotoxicity against HaCaT keratinocytes, while cosmetic cream could alleviate their cytotoxicity. Moreover, the cream could enhance the accumulation of Au NSs and NRs in the skin of hairless mice, but it also alleviated the toxicological responses of Au NSs and NRs in terms of superoxide dismutase (SOD) elevation and malondialdehyde (MDA) reduction. Therefore, the embedment of Au NSs and NRs into cosmetics can alleviate the in vitro and in vivo dermal toxicities of Au NSs and NRs.Keywords:gold nanomaterials;cosmetics;toxicity reduction;skin

Currently, illegal addition of anti-infective drugs has been detected in some cosmetics to achieve rapid sterilization and anti-inflammatory effects. However, the abuse of anti-infective drugs may endanger the health of citizens. Thus, methods for the detection and quantitative determinations of such substances should be developed. In this paper, a method combining ultra-high-performance liquid chromatography with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF HRMS) was designed. Its significance and potential were verified by the identification, confirmation, and quantification of 37 illegally added anti-infective drugs in cosmetics that claimed to have anti-acne effects. The method validation revealed a satisfactory linear relationship, and each coefficient of determination ( r 2 ) was higher than 0.9943. The LOD and LLOQ results were in the ranges of 0.0003–0.1063 μg g −1 and 0.0012–0.3545 μg g −1 , respectively. The accuracy ranged from 70.8 to 122.8%, whereas the intra- and inter-day precisions were in the ranges of 0.2–12.8% and 0.2–13.8%, correspondingly. The mean recoveries were in the range of 70.1–117.7%, and the matrix effects ranged from 73.0 to 121.4%. Of the 200 batches of cosmetics that claimed to have anti-acne effects, three batches were positive, with chemical components such as metronidazole, lincomycin, clindamycin, tinidazole and miconazole nitrate being discovered. Therefore, the Q-TOF spectrometry could be widely applied in routine screening of adulteration in cosmetics.

Preservatives can be used in natural and organic cosmetics to prevent quality deterioration during distribution and use, but the ingredients permitted are limited in the Republic of Korea. A method of simultaneous analysis was developed to monitor natural and organic cosmetics distributed online for the presence of 15 illegally used preservatives. Considering the complexities of the cosmetic matrices, an optimized sample preparation method is essential. Therefore, we developed the optimal purification method by comparing three preparation methods: QuEChERS, high-speed centrifugation, and solid-phase extraction (SPE). The SPE method, which exhibited the most favorable results in matrix reduction, was employed. To establish the SPE-ultra-high-performance liquid chromatography-diode array detection method, factors such as the mobile phase and column were optimized. The optimal separation of the 15 preservatives was observed under the following conditions: mobile phase A comprising 0.1% phosphoric acid in water with 0.5 mM sodium hexanesulfonate and a C 8 column (1.7 μm, 2.1 × 150 mm) as the stationary phase. The linear correlation coefficients were > 0.9998, and the limits of detection and quantitation ranged from 0.05 to 0.67 and 0.15 to 2.02 μg mL −1 , respectively. Using the established analytical method, illegally used preservatives were detected in products claimed to be natural and organic cosmetics sold on the market, and these findings were subsequently verified using liquid chromatography-tandem mass spectrometry. Six out of 47 samples contained phenoxyethanol and parabens. Therefore, this method will help manage the addition of illegal preservatives to natural and organic cosmetics.

A new micellar electrokinetic capillary chromatography (MEKC) method combined with field-amplified sample injection (FASI) has been developed for the analysis of isonicotinamide and nicotinamide in whitening cosmetics and supplemented foodstuffs. Parameters affecting FASI preconcentration and MEKC separation were optimized systematically. Compared with direct MEKC, the sensitivity of FASI-MEKC was improved by 12.8- and 9.8-fold for isonicotinamide and nicotinamide, respectively. The detection limits (LODs) of isonicotinamide and nicotinamide were 0.051 μg mL−1 and 0.069 μg mL−1, respectively, with RSD (intraday) < 4.9% (n = 7, c = 0.5 μg mL−1) and RSD (interday) < 6.4% (n = 5, c = 0.5 μg mL−1). The proposed method was successfully applied in determination of isonicotinamide and nicotinamide in whitening cosmetics and supplemented foodstuffs with acceptable recoveries of 84.7–108.4%.

Astaxanthin , a pink/red pigmented keto carotenoid occurring in certain algae, is an anti-oxidant that protects the cell from damage by attenuating the reactive oxygen species due to which it has immense potential to protect the skin and other allied cells. Commercially available chemical UV-filters used in sunscreen creams and lotions are not only inadequate in protecting the skin against the harmful UV-rays but also cause skin damage like skin irritation , skin-aging, allergic reactions upon prolong exposure to these chemicals. Moreover, they cause environmental pollution and damage, mainly to aquatic life . So, natural compounds having similar or improved protective potential against UV irradiated skin are in dire need in the cosmetics industry. Recent studies substantiate that astaxanthin can be employed in sunscreens owing to its high antioxidant potential and significant use as an anti-aging, anti-inflammatory, and anti-cancer compound. Astaxanthin accumulation has been found in microalgae and its properties suggest that astaxanthin can provide total protection against all the UVR related skin problems starting from the acute effects of sunburn, pigmentation , erythema to chronic effects of inflammation, photoaging and skin cancer. In this paper, astaxanthin's importance, sources, chemical structure, pilot scale production and its potential applications in cosmetic industry have been discussed.

In this study, a new magnetic molecularly imprinted polymer Fe 3 O 4 @MIP is prepared via a surface molecularly imprinting technique; it is first applied as a magnetic solid phase extraction (MSPE) adsorbent for the selective and rapid extraction of kojic acid (KA) in cosmetic products. The as-prepared Fe 3 O 4 @MIP is characterized systematically, and is found to exhibit good monodispersity and high magnetic susceptibility in favor of fast separation. The adsorption capacity and equilibrium time of KA on the Fe 3 O 4 @MIP adsorbent are 314.0 mg/g and 30 min, respectively. In addition, the imprinting factor of Fe 3 O 4 @MIP is 2.09 for KA, which indicates that the prepared Fe 3 O 4 @MIP exhibits good selectivity for KA. Under the optimum experimental conditions, the KA in cosmetic products was successfully extracted with Fe 3 O 4 @MIP adsorbent and determined by ultraviolet–visible (UV–vis) spectrophotometry. Validation experiment shows that the developed method presents good linearity (50–500,000 μg/L), satisfactory precision (RSD, 2.5–4.6 %), and high recovery (92.4–104.6 %). The limit of detection (LOD) is 21.4 μg/L, and the enrichment factor is 299. These results suggest that this MSPE method coupled with UV–vis spectrophotometry holds great potential for efficient sample pretreatment and target molecule determination in real samples.

In this work, we report a rapid analytical method for the determination of trace formaldehyde in cosmetics on a 12.5 mm C18 guard column. The shortest time (0.5 min) was obtained for one separation with 1.5 mL min−1 of methanol–water 50 : 50 (v/v) as the mobile phase at a column temperature of 30 °C. A linear response between peak area and the concentration of formaldehyde was obtained over the range 0.1 to 20 mg L−1 with a relative standard deviation of 1.4% (n = 10) at the concentration of 1.0 mg L−1 and a detection limit of 5.1 μg L−1. The confirmation assay by liquid chromatography tandem mass spectrometry indicated that there was no interfering effect from other carbonyl compounds. The proposed method was applied for the determination of formaldehyde residue in cosmetics at the mg L−1 level. Free formaldehyde up to 27 mg kg−1 was found in cosmetics and the spike recovery at the spiked levels of 1.0 and 10.0 mg L−1 varying from 92% to 105% was also obtained. The difference between the values determined by the proposed method and the standard spectrophotometric method was below 3.7%. The results proved the accuracy and precision of the method, showing potential for the routine analysis of formaldehyde residue.

Mercury is one of the most potentially toxic metals, which is much harmful to the human health. Therefore, It is great important to detect mercury ions . In this work, proposed was a simply visual and rapidly colorimetric strategy for detection of Hg 2+ based on gold nanoparticles (AuNPs) modified with sulfadiazine (SDZ) and characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS), X-ray powder diffraction (XRD), UV–vis. The solution color from red to blue gray with increasing Hg 2+ concentration resulted from the aggregation of AuNPs with fine anti-interference. The limit of detection (LOD) is 1.0 μg·mL -1 by the naked eye, and 0.071 μg·mL -1 by UV–vis spectroscopy with the good linear relationship (R 2 = 0.994) indicating that AuNPs modified with sulfadiazine could be used for the quantitative determination of Hg 2+ . The selectivity of SDZ-AuNPs detection system for Hg 2+ is much more excellent compared with other interferents in cosmetics, which exhibit this sensor could be successfully applied to detect Hg 2+ in real samples.

Akebia trifoliata (Thunb.) Koidz is gaining popularity, because of its high nutritional, economic and medicinal values. The purpose of this study was to optimize the extraction conditions of A. trifoliata (Thunb.) Koidz polysaccharide (ATKP) and investigate moisturizing activity to prepare a novel moisturizing cosmetic material. It has been observed that using polysaccharide yield as the evaluation criterion showed optimal extraction at a material-liquid ratio of 1:20, an ultrasonic temperature of 80 °C, an ultrasonic time 50 min and ultrasonic power of 175 W. Furthermore, three deproteinization methods of ATKP process, including Sevag, enzymatic hydrolysis and their combination method, were evaluated. The deproteinization efficiency of the Sevag and enzymatic hydrolysis combination method was the highest, with a deproteinization efficiency of 87.52 %. The moisturizing capacity of ATKP was significantly higher than that of chitosan and sodium alginate . ATKP-containing skin cream, particularly the combination of 4.2 % glycerol and 0.8 % ATKP, had an excellent moisturizing effect, and was added to cosmetic formulations to form skin creams. The findings revealed that ATKP has the potential synergistic effect with glycerol in the development of cosmetic formulations, which could be used as a new material for natural moisturizers.
