Abstract In Japan, cosmetics claiming hormesis effect are available through Internet. Although these cosmetics show the contents, they never mention the minor elements and radioactive sources. The existence of radioisotopes, however, was obsd. by measurements of the gamma-rays with a HPGe detector. In this study, to clarify the contents of trace elements, the hormesis cosmetics including radioactive sources were analyzed using INAA, PGAA, and NAA with multiple gamma-ray detection (NAAMG). Nineteen elements were analyzed quant. in hormesis cosmetics by INAA, PGAA, and NAAMG and 16 elements were detected qual. by SEM-EPMA.

Abstract An extremely small amt. of several heavy metals have been detected in cosmetic products as impurities, which can cause skin allergies through percutaneous adsorption on the skin. We present here a fast, accurate, and highly sensitive method for simultaneous detn. of Pb2+, Fe2+, Cu2+, Ni2+, Zn2+, Co2+, Cd2+ and Mn2+ in coloring agents and cosmetic products, to be evaluated by ion chromatog. All of these metals are well sepd. through a bifunctional ion-exchange column (IonPac CS5A) and detected by post-column reaction and spectrophotometric detection. The calibration graphs are linear (r2 > 0.999), in the range 0.1-1000 mg/mL. Detection limits for a 200-ml sample soln. are at the mg/l level, which is sufficient for judging whether the product is safe or not. The relative std. deviations (RSDs) of the retention time and the peak area are less than 0.21% and 1.24%, resp. The recovery rates are 97-104%. The result shows that the proposed detn. method is more sensitive, more accurate, and faster than current methods such as HPLC, ICP-MS and Flame-AAS. The new method was applied to analyze the amt. of heavy metals contained in 22 cosmetic products and 11 coloring agents.

Abstract This study looks at the chem. compn. of traditional eye cosmetics ("kohls") used in Qatar and Yemen. Of especial interest was how many samples in each country contain the toxic element lead. In Qatar 19 observably different kohl samples were obtained, and in Yemen ten such samples obtained. The anal. techniques of SEM and x-ray powder diffraction (XRPD) were used to study the samples. For the samples from Qatar, six of the 19 (32%) contained galena (lead sulfide, PbS)-all as the main component. However, for the samples from Yemen, five of the ten (50%) samples contained galena as the main component, with another three having it present as a minor component. Overall, the other main components were found to be: amorphous carbon (3), iron oxides (hematite, Fe2O3; and goethite, FeO(OH)) (1), quartz (SiO2) (1), sassolite (H3BO3) (5), talc (Mg3Si4O10(OH)2) (1), and zincite (ZnO) (7).

Abstract Microsamples of pink cosmetic powders from the Greco-Roman period were analyzed using two complementary anal. approaches for identification of the coloring agents (lake pigments originally manufd. from madder plants with an inert binder, usually a metallic salt) present in the samples. The first technique was a methanolic acidic extn. of the archaeol. samples with an addnl. Et acetate extn. of the anthraquinone-type coloring agents which were identified using high performance liq. chromatog. coupled to electrospray ionization with high resoln. mass spectrometry (LC-ESI-HRMS), and the second was direct anal. of a microsample by laser desorption ionization-mass spectrometry (LDI-MS). The latter technique is well suited when the quantity of samples is very low. This soft ionization technique enables the detection of very small quantities of compds. using the combination of pos. and neg.-ion modes. It was also successfully applied for the direct anal. of some lab.-made ref. compds. However, the presence of lead in one of these ancient samples induced a spectral suppression phenomenon. In this case and conditional on a sufficient quantity of available sample, the former method is better adapted for the characterization of these anthraquinone-type mols. This study also confirmed that purpurin, munjistin, and pseudopurpurin are the principal coloring agents present in these ancient cosmetic powders constituted from madder plants.

Abstract Lead white pigment was used and synthesized for cosmetic and artistic purposes since the antiquity. Ancient texts describe the various recipes, and prepn. processes as well as locations of prodn. In this study, we describe the results achieved on several paint samples taken from Matthias Gruenewald's works. Gruenewald, who was active between 1503 and 1524, was a major painter at the beginning of the German Renaissance. Thanks to X-ray diffraction anal. using synchrotron radiation, it is possible to assoc. the compn. of the paint samples with the masters ancient recipes. Different approaches were used, in reflection and transmission modes, directly on minute samples or on paint cross-sections embedded in resin. Characterization of lead white pigments reveals variations in terms of compn., graininess and proportion of mineral phases. The present work enlightens the presence of lead white as differentiable main compn. groups, which could be specific of a period, a know-how or a geog. origin. In this way, we aim at understanding the choices and the trading of pigments used to realize paintings during northern European Renaissance.

Abstract A true direct solid sampling electrothermal at. absorption spectrometry method with Zeeman-effect background correction (Analytik Jena ZEEnit 60 AAS) was developed for the detn. of As, Cd, Hg, Pb, Sb and Zn in powd. TiO2 of pharmaceutical, food and cosmetics grade. The interaction of the Ti matrix and graphite surface of the sample carrier boat in a transversely heated graphite tube atomizer was studied. Conversion of TiO2 to interfering TiO2-TiC-liq. phase, running out the sampling boat, was obsd. at temps. >2000°. The temp. program was optimized accordingly for these volatile analytes in atomization and cleaning steps to prevent this interference and to prolong significantly the anal. lifetime of the boat to more than one thousand runs. For all elements, calibration by aq. std. addn. method, by wet-chem. analyzed samples with different content of analytes and/or by dosing one sample in different amts., were proved as adequate quantification procedures. Linear dynamic calibration working ranges can be considerably expanded up to two orders of magnitude within one measurement run by applying three-field dynamic mode of the Zeeman background correction system. The results obtained by true direct solid sampling technique are compared with those of other independent, mostly wet-chem. methods. Very low limits of detection (3s criterion) of true solid sampling technique of 21, 0.27, 24, 3.9, 6.3 and 0.9 ng g-1 were achieved for As, Cd, Hg, Pb, Sb and Zn, resp.

Abstract Lead soaps can be found in archaeol. cosmetics as well as in oil paintings, as product of interactions of lead salts with oil. In this context, a better understanding of the formation of lead soaps allows a follow-up of the historical evolution of prepn. recipes and provides new insights into conservation conditions. First, ancient recipes of both pharmaceutical lead plasters and painting lead media, mixts. of oil and lead salts, were reconstructed. The ester sapon. by lead salts is detd. by the prepn. parameters which were quantified by FT-IR spectrometry. In particular, ATR/FT-IR spectrometer was calibrated by the std. addn. method to quant. follow the kinetics of this reaction. The influence of different parameters such as temp., presence of water and choice of lead salts was assessed: the sapon. is clearly accelerated by water and heating. This anal. provides chem. explanations to the historical evolution of cosmetic and painting prepn. recipes.

Abstract This study was undertaken in order to det. the availability and chem. compn. of potentially lead-toxic traditional eye cosmetics ("kohls") in six of the seven emirates of the United Arab Emirates (UAE). Thus of especial interest was the percentage of the purchased samples that contained the toxic element lead. A total of 53 observably different kohl samples were found to be available overall in the six emirates: Dubai, Sharjah, Ajman, Umm Al-Quwain, Ras Al-Khaimah, and Fujairah. It was found that 19 of these samples were previously analyzed in studies covering Oman, Abu Dhabi (city), and Egypt (Cairo). The techniques of x-ray powder diffraction (XRPD) and SEM were used to analyze the remaining 34 samples. Overall, for the 53 kohl samples, it was found that 20 (38%) contained a lead compd. (galena, PbS) as the main component. The other main components were found to be one of the following: amorphous carbon, calcite/aragonite (CaCO3), goethite (FeO(OH)), hematite (Fe2O3), sassolite (H3BO3), talc (Mg3Si4O10(OH)2), or zincite (ZnO).

Abstract Several facial cosmetics available in Nigeria were analyzed for their contents of the heavy metals; lead, cadmium, chromium, nickel, zinc and iron. The levels of chromium, iron and zinc were much higher in the samples than those of the non-essential toxic metals; lead, cadmium and nickel. The range of the geometric av. for the various cosmetics is: Fe, 97-256 mg/g; Ni, 8-13 mg/g; Pb, 87-123 mg/g; and Zn, 88-101 mg/g. The geometric mean values obtained for Cr and Cd were generally below 40 mg/g and about 1 mg/g, resp. Our result indicates that these cosmetics are relatively safer to use when compared to the lead-based kwali eye make-up commonly available in Nigeria. These data indicate that the continuous use of these cosmetics could result in an increase in the trace metal levels in the ocular system and the human body beyond acceptable limits. The application of these cosmetics needs to be considered as a source of lead in evaluating patients with symptoms of lead intoxication in regions where this practice is common.

Abstract Synchrotron IR micro-spectroscopy is appropriately suited to the anal. of small particles of archaeol. cosmetics. The sample originates from a 33 centuries old Egyptian cosmetic remain. Thanks to the high spectral quality and high lateral resoln. achieved by this synchrotron-based microspectroscopic tool, new insights into the compn. and spatial location of both org. and mineral components of the sample were obtained. Five different particles were analyzed and delivered similar findings: the core is fat rich, and surrounded with a mineral phase. In two particles, lead palmitate was clearly identified as a major component. Phosgenite (Pb2CO3Cl2), a lead salt synthesized in aq. soln., was also located in region near the surface of the particles.

Abstract Seventeen samples of cosmetic emulsions for skin care were obtained by randomly buying samples from Bodija open market in Ibadan, Nigeria. The samples were analyzed comparatively for the following parameters: emulsion type, pH, cond., water content, total volatile, total non volatile matter, acid value, ester value, and sapon. value. Levels of heavy metals like lead and iron were also detd. The results obtained indicate that the samples were mostly oil in water emulsion type. Conductivities of samples ranged from 0.2 mscm-1 to 46 mscm-1 with pH mostly close to neutral range (6.0 - 7.8) and having large quantity of water incorporated during emulsion formation. The low sapon. values (0.16 - 18.12 mgKOH/g) of the samples pointed to the fact that the samples were mostly paraffin based and most likely consisted of paraffin oil, paraffin wax, petroleum jelly, and beeswax that do not easily saponify. The samples also had low fatty acids and ester values (0.16 - 4.80 mg KOH/g and 0.00 - 13.32 mgKOH/g resp.) indicating the lack of use of animal or vegetable oils. Iron levels in the emulsion ranged from 0.1 ppm - 4.3 ppm, showing that most of the companies did not use deionized water. Only 1 sample contained lead at a level of 0.1 ppm showing that the hydrocarbons used in the formulation of the emulsions and the water used were relatively unpolluted. The general indications are that the cosmetic emulsions though stable will not be of much use for proper therapeutic treatment of dry skin conditions, but may be useful for temporary relieve of skin dryness.

Abstract Citrus essential oils are widely used in the food, cosmetics, and pharmaceutical industries, so the detn. of heavy metals content is of great importance to guarantee their quality. The present work deals with the quantification of Cd(II), Cu(II), Pb(II), and Zn(II) in different varieties of citrus essential oils, using deriv. potentiometric stripping anal. Two different metals extn. procedures, involving concd. HCl treatment and acid-alc. dissoln., are tested on lemon, mandarin, sweet orange, and bergamot essential oils, and they give very similar results. Cd(II), Cu(II), Pb(II), and Zn(II) recovery tests spanned from 95 to 100.50%, providing evidence that metals quantification remained unaffected by the cleanup steps of the 2 procedures. The repeatability of the HCl extn. method, applied on different varieties of essential oils, is >95.00% for Cd(II), Cu(II), Pb(II), and Zn(II), whereas the repeatability of the acid-alc. dissoln. method is >93.00% for Cu and Cd only in lemon oil. Detection limits obtained for the 4 analytes, using both procedures, ranged from 0.10 to 0.98 ng/g in lemon, mandarin, sweet orange, and bergamot essential oils.
