Determination of ultra-trace gold in cosmetics using aluminum-magnesium layered double hydroxide/graphene oxide nanocomposite.

A new solid-phase microextraction system for preconcentration and determination of ultra-trace Au and AuNPs was introduced. The synthesized nanomaterial allows sorption of AuNPs with 100% recovery at pH 1-5 or AuNPs and Au ions at pH 1-2. Consequently, gold ions and the corresponding gold nanoparticles can be mixed or separately determined. precision ca. , gold was directly determined on the AlMg-LDH/GO by energy-dispersive X-ray fluorescence spectrometry with a detection limit of 0. 06 ng mL -1, precision ca. after adsorption, gold was positively determined on the AlMg-LDH/GO by energy-dispersive X-ray fluorescence spectrometry with a precision limit of 0. 06 ng mL -1 X-quality The developed technology was used to extract and identify ultra-trace gold in cosmetics products, which was successfully applied.

An analysis of 275 DIY recipes for eye cosmetics and their possible safety issues.

This research seeks to investigate eye makeup and makeup removal solutions, as well as eyelash and eye contour care products. We found recipes for do-it-yourself products on blogs and social media in French and English, then we'll look at their composition as well as how practical it is to make these dishes. The findings reveal that recipes for eye or periocular use are not safe to use, and that their use is likely to have significant effects.

Applications and Prospects of Nanotechnology in Food and Cosmetics Preservation.

The use of nanotechnology in food and cosmetics for preservation purposes has the ability to increase the activity of antimicrobial agents and/or promote their safer distribution into the end product on incorporation into packaging or film fabrications. In this review, current preservation techniques are discussed and analyzed in a way that hopefully provides the most promising solutions for both product safety enhancement and shelf-life extension. Conclusion: Nanomaterial science has already made a contribution to food and cosmetics preservation, and rapid developments in the last years have renewed the belief that the majority of the preservation plans pursued by the two industries will be based on NPs and their nanocomposites.

Ethnopharmacology for Skin Diseases and Cosmetics during the COVID-19 Pandemic in Lithuania.

This is the first study in Lithuania, specifically dedicated to ethnopharmaceuticals used for skin diseases and cosmetics, and the first study to analyze ethnopharmacology as a Lithuanian phenomenon during the ongoing COVID-19 pandemic. During the COVID-19 pandemic from July 2020 to October 2021, the primary aim of this research was to gather and analyze ethnopharmaceutical data concerning skin diseases and cosmetics in iauliai District, Lithuania. The respondents reported 67 species of medicinal plants from 37 different families used for skin diseases, cosmetics, and cosmeceuticals. Only 43 species of the 67 plant species were not included in the European Medicines Agency's monographs, and only 14 species of all included species were used with European Medicines Agency approved medical indications for skin diseases.

Enhanced capillary zone electrophoresis in cyclic olefin copolymer microchannels using the combination of dynamic and static coatings for rapid analysis of carnosine and niacinamide in cosmetics.

In cyclic olefin copolymer microchips with both dynamic and static coatings, capillary zone electrophoresis was carried out to produce quick and accurate quantitation of carnosine and niacinamide in cosmetics. The static coating of cyclic olefin copolymer microchannel was produced from bovine serum albumin adsorption, immobilization, and permanent site closure, while the conductive coating was applied by adding surfactant to the running buffer of capillary zone electrophoresis. The static coating will increase the cyclic olefin copolymer surface's hydrophilicity and prevent nonspecific peptide adsorption. In the capillary zone electrophoresis separation channel of the cyclic olefin microchip device, the dynamic coating of sodium dodecyl sulfate in running buffer proved to be helpful in flow velocity adjustment and column improvement.

Nickel and cobalt release from beauty tools: A field study in the German cosmetics trade.

Methods/materials The test of seven beauty salons in two North-German states was performed in seven beauty salons located in seven beauty salons. The tools for nickel testing and cobalt manufacturing were evaluated with a nickel spot test and a cobalt spot test, respectively. The Cobalt and one hundred forty-three of 308 beauty products total were released nickel and 18 of 308 beauty products were cobalt. Nickel release was discovered in 22 of 99 metal tools and 121 of 209 metal parts; cobalt was detected in 3 of 99 metal tools and 15 of 209 metal parts; cobalt was detected in 15 of 199 tools with metallic parts.

Nanotechnology in Cosmetics and Cosmeceuticals-A Review of Latest Advancements.

Nanotechnology in cosmetics has been shown to eliminate traditional cosmetics' drawbacks and to include more useful attributes to a formulation. Nanocosmetics and nanocosmeceuticals have been extensively investigated for skin, hair, nails, lips, and teeth, and teeth, and the use of nanomaterials has been shown to increase product performance and customer satisfaction. However, nanotoxicological studies on nanocosmeceuticals have raised questions in terms of health risks due to their potential skin penetration, which has resulted in toxic effects. This article, in turn, seeks to give an overview of nanocosmetics and nanocosmeceuticals and their applications in cosmetic industries, allowing consumers and regulators to be aware of the benefits as well as the risks inherent to these products' continuous and long-term use, thus encouraging their judicious use.
