Silver nanoparticles assessment in moisturizing creams by ultrasound assisted extraction followed by sp-ICP-MS

Analytical applications of single particle inductively coupled plasma mass spectrometry: a comprehensive and critical review

“…41 Other studies have included quality control procedures, such as the evaluation of trueness by spiking nanoparticles standards to natural matrix samples, considering that conventional procedures cannot be directly applied in SP-ICP-MS analysis due to the limitations described above. Thus, trueness has been evaluated by measuring recovery of the spiked nanoparticles, mainly based on number concentration, and the use of alternative techniques to confirm size results, such as for the sizing and quantification of Ag nanoparticles in food simulants, 52 moisturizing creams, 53 fish tissue, 54 or ZnO 55 and TiO 2 nanoparticles 56 in natural waters. This strategy has also been applied to the detection of naturally occurring iron oxide nanoparticles in crude oil and residual fuel oil by spiking in-lab synthesized silica-shelled Fe 3 O 4 nanoparticles.…”

“…Owing to their specific properties at the nanoscale level, nanoparticles are currently contained in numerous consumer and industrial products. The nano-enhanced products analysed by SP-ICP-MS are summarized in Table 3; they consist of consumer, mainly cosmetics, 53,[77][78][79][80][81][82][83][84][85] and industrial products, including food additives 43,46,89 and other materials, like steel, 90 petroleum products 57,91 or tattoo inks. 92,93 Nanoparticles in cosmetics are mainly focused on sunscreens, [77][78][79]84 in which TiO2 is the most frequent nanocomponent due to its photocatalytical properties, although ZnO has also been studied in this type of products.…”

“…80,81 TiO 2 was the target analyte in other cosmetics and personal care products, like toothpastes, 82,83 lip balms, 82,84 creams 84 and shampoos. 84 Aluminium oxide and silver nanoparticles in toothpastes 83 and moisturizing creams, 53 respectively, have also been measured by SP-ICP-MS, as well as plastic microparticles added as abrasives in exfoliant creams. 85 Sample preparation of cosmetics always requires their dispersion in ethanol or water, in most cases by adding a surfactant, although a previous defatting step with hexane is typical for sunscreens and lip balms.…”

Nanotechnology meets atopic dermatitis: Current solutions, challenges and future prospects. Insights and implications from a systematic review of the literature

“…Nanoparticles and nanocarriers seem to have optimal rheological properties, antimicrobial effects and capability to restore skin conditions. These nanostructures, such as silver (Ag-NPs) and silver-lipid or poly(lactic acid) (PLA-NPs) nanoparticles [[25], [26], [27], [28], [29]] appear promising in the treatment and management of patients with atopic dermatitis.…”

Potential of Topical Cosmeceuticals Cream Functionalized with Biogenic Metallic Nanostructured Material as Antibacterial Agents

“…Cosmetics product incorporated with nanoparticles provide light scattering, tactile, and matte effects to end user. Metallic nanomaterials have been used to improve the performance of a wide range of cosmetic products, including moisturizer [5], antiaging cream [6], hydrogel [1], and perfume base dermal dressings [7]. Nanostructures zinc oxide, titanium dioxide, zircornium dioxide, and cerium oxide are widely used in sunscreen to protect skin from UV radiation [8].…”
