“…La-containing NPs were also reported (Figure S2) to provide additional insights into particle origins. Based on global production volumes, ,, we would expect La-containing NPs to be predominantly from natural sources, Ce- and Ti-NPs to be from both natural and anthropogenic sources, and Ag-NPs to be predominantly from anthropogenic sources.…”

“…1,5,6 Engineered NPs have been developed due to their generally enhanced chemical reactivities with respect to bulk materials of similar composition, which implies enhanced biological reactivity and potentially increased risk. 7 To date, the vast majority of data on NP concentrations in the environment have been extrapolated from global production volumes 8 and (often assumed) product release rates 9 generated through modeling 10 and based on contaminant transport patterns. 11,12 The authors of these studies have systematically noted a very large uncertainty due to the poor quality of input data, the use of a large number of simplifying assumptions, and the limited inclusion of environmental fate processes (e.g., agglomeration, heteroaggregation, dissolution, and phase transformations).…”

Nanoparticle (NP) emissions to the environment are increasing as a result of anthropogenic activities, prompting concerns for ecosystems and human health. In order to evaluate the risk of NPs, it is necessary to know their concentrations in various environmental compartments on regional and global scales; however, these data have remained largely elusive due to the analytical difficulties of measuring NPs in complex natural matrices. Here, we measure NP concentrations and sizes for Ti-, Ce-, and Ag-containing NPs in numerous global surface waters and precipitation samples, and we provide insights into their compositions and origins (natural or anthropogenic). The results link NP occurrences and distributions to particle type, origin, and sampling location. Based on measurements from 46 sites across 13 countries, total Ti-and Ce-NP concentrations (regardless of origin) were often found to be within 10 4 to 10 7 NP mL −1 , whereas Ag NPs exhibited sporadic occurrences with low concentrations generally up to 10 5 NP mL −1 . This generally corresponded to mass concentrations of <1 ng L −1 for Ag-NPs, <100 ng L −1 for Ce-NPs, and <10 μg L −1 for Ti-NPs, given that measured sizes were often below 15 nm for Ce-and Ag-NPs and above 30 nm for Ti-NPs. In view of current toxicological data, the observed NP levels do not yet appear to exceed toxicity thresholds for the environment or human health; however, NPs of likely anthropogenic origins appear to be already substantial in certain areas, such as urban centers. This work lays the foundation for broader experimental NP surveys, which will be critical for reliable NP risk assessments and the regulation of nano-enabled products.

“…In 2006, the cosmetics giant Estèe Lauder also began employing nanotechnology in its cosmetic products [22], followed by Procter & Gamble, Johnson & Johnson, Avon, Colorscience, and Doctor's Dermatologic Formula [21,22]. Today, almost 40 years later, the use of nanotechnology in marketed cosmetic products worldwide is so widespread [18][19][20][21][22]78,79], that current attempts to categorize them (Table 3) fast become out of date, while updated distributions can be obtained from comprehensive market reports, performed by advanced technology consultancies [80]. On the other hand, additional information on marketed cosmetic products that contain nanosystems can be gathered from two freely available resources [80].…”

Nanosystems in Cosmetic Products: A Brief Overview of Functional, Market, Regulatory and Safety Concerns

et al. 2021

View full text Add to dashboard Cite

Nanosystems exhibit various innovative physico-chemical properties as well as a range of cosmetic functions, including increased skin retention for loaded compounds. The worldwide nano-market has therefore been consistently extensive in recent decades. This review summarizes the most important properties of nanosystems that are employed in cosmetics, including composition, functions and interactions with skin, with particular attention being paid to marketed products. Moreover, the worldwide regulatory landscape of nanomaterials used as cosmetic ingredients is considered, and the main safety concerns are indicated. In general, advanced physico-chemical characterization is preliminarily needed to assess the safety of nanomaterials for human health and the environment. However, there is currently a shortfall in global legislation as a universally accepted and unambiguous definition of a nanomaterial is still lacking. Therefore, each country follows its own regulations. Anyhow, the main safety concerns arise from the European context, which is the most restrictive. Accordingly, the poor dermal permeation of nanomaterials generally limits their potential toxic effects, which should be mainly ascribed to unwanted or accidental exposure routes.
