Media articles have claimed that “synthetic mineral oil saturated hydrocarbons (MOSH)”, which are used in many cosmetics such as lip balms, are unsafe at any dose and should be replaced with natural alternatives. This paper examines whether these claims are correct and whether the perceived safety of these substances is influenced by the language used in the media. To achieve these goals, it first provides an extensive review of the toxicology literature, finding no support that MOSHs are unsafe at current usage levels. It then reviews the psychology literature to examine the effects of labelling a cosmetic ingredient as “natural” rather than “synthetic” and the effects of dose information. A 2 × 2 between-subjects experiments involving adult lip balm users shows that, as hypothesized, the perceived safety of lip balms increases when they are described as containing “naturally sourced mineral oil” rather than “synthetic mineral oil saturated hydrocarbon (MOSH)”, which are both correct descriptions. In addition, the perceived safety increases when the substance is described as being present in a low vs. a high dose, regardless of whether it was described as natural or synthetic. Overall, safety perceptions for common cosmetic substances can be significantly influenced by the language used in media reporting.

Preimplatation embryos grown in vitro are sensitive to their environment, and the conditions of culture can affect developmental potential. Progesterone (P4) is the key hormone responsible for maintenance of pregnancy in mammals, and circulating levels in the early postconception period have been associated with pregnancy success. It is not clear whether P4 acts directly or indirectly on the embryo to alter gene expression and development. The aim of this study was to assess the effect of varying levels of exogenous P4 on the development of bovine zygotes to the blastocyst stage in vitro. A preliminary study was conducted to analyze the media used for culture (stock of P4, SOF, SOF + 1 × 10–7 M P4) on Days 1 (day of culture), 4, and 7 for P4 concentration in 25-μL droplets overlain with mineral oil or 500 μL in wells with or without mineral oil. P4 was measured using an ELISA kit, prepared for human serum or plasma (DE1561 Dimeditec Diagnostics GmbH, Kiel, Germany). Inter- and intra-assay coefficients of variation were 6.63 and 6.42%, respectively, and recovery was 95%. P4 concentration on Day 1 in all media was the expected (40 ng mL–1). However, on Days 4 and 7 in media under mineral oil, the level of P4 was nearly zero (0.1 to 1.6 ng mL–1) compared with the media without mineral oil, which remained unchanged (39 to 40 ng mL–1) through the 7 days of culture. Zygotes (n = 1467) were produced in 8 replicates by in vitro oocyte maturation and fertilization, and were cultured in groups of 40 to 50 in wells of 500 μL without mineral oil in (1) SOF supplemented with 5% fetal calf serum (control–), (2) SOF with ethanol (control+), (3) SOF with P4 0.1 × 10–7 M, (4) SOF with P4 1 × 10–7 M, and (5) SOF with P4 10 × 10–7 M at 39°C, 5% CO2 and 5% O2, with maximum humidity. No significant difference was found between groups in cleavage rate or blastocyst yield on Days 6, 7, and 8 (Table 1). These results indicate that the addition of P4 to the in vitro culture medium (SOF) did not enhance the development of bovine embryos to the blastocyst stage. However, further studies on the quality of these embryos in terms of gene expression are in preparation. Table 1. Effect of P4 on bovine in vitro early embryo development

A method was developed for the determination of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) in edible oils, achieving similar limits of quantification than those obtained by online extraction methodologies, i.e., 0.5 mg/kg. The isolation of MOSH and MOAH was performed in a silver nitrated silica gel stationary phase prior to their analysis by gas chromatography–flame ionization detector (GC-FID). To improve the sensitivity, the simulated on-column injection method, using a suitable liner, was optimized. The method was validated at 0.5, 10.0 and 17.9 mg/kg, and recoveries ranged from 80 to 110%. Intra and inter-day precision were evaluated at the same levels, and relative standard deviation (RSD) was lower than 20%. The method was applied to a total of 27 samples of different types of oil previously analyzed in an accredited laboratory, detecting MOSH up to 79.2 mg/kg and MOAH up to 22.4 mg/kg.

Mineral oils which consists mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH), which are largely applied in various consumer products like medicines cosmetics etc. MOAH which is potential public health hazard because it include carcinogenic polycyclic compounds. There is a rapid method for quantifying MOAH by proton nuclear magnetic resonance spectroscopy (1H qNMR) in anhydrous cosmetics. The 1H qNMR method is a good complement to the LC-GC-FID method. Another method is a simple and fast developed that uses columns packed with silver-modified silica in supercritical fluid chromatography with flame ionization and UV detection (SFC-FID/UV) for the determination of mineral oil saturated hydrocarbons (MOSH) and also mineral oil aromatic hydrocarbons (MOAH) in purified mineral oil samples. Another method which is based on gas chromatography with vacuum ultraviolet detection (GC-VUV) and relies on the spectral differences between the aliphatic and aromatic compounds in the sample. The detector provides a good selectivity for aromatics, direct quantification of the MOAH content is possible without the need for a laborious pre-separation of the mineral oil. GC-VUV method good sensitive for the analysis of all but gives highest purity mineral oils.

Mineral oils (such as paraffinum liquidum or white oil), which consist of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH), are widely applied in various consumer products such as medicines and cosmetics. Contamination of food with mineral oil may occur by migration of mineral oil containing products from packaging materials, or during the food production process, as well as by environmental contamination during agricultural production. Considerable analytical interest was initiated by the potential adverse health effects, especially carcinogenic effects of some aromatic hydrocarbons. This article reviews the history of mineral oil analysis, starting with gravimetric and photometric methods, followed by on-line-coupled liquid chromatography with gas chromatography and flame ionization detection (LC-GC-FID), which still is considered as gold standard for MOSH-MOAH analysis. Comprehensive tables of applications in the fields of cosmetics, foods, food contact materials, and living organisms are provided. Further methods including GCxGC-MS methods are reviewed, which may be suitable for confirmation of LC-GC-FID results and identification of compound classes. As alternative to chromatography, nuclear magnetic resonance (NMR) spectroscopy has recently been suggested for MOSH-MOAH analysis, especially with the possibility of detecting only the toxicologically relevant aromatic rings. Furthermore, NMR may offer potential as rapid screening especially with low-field instruments usable for raw material control.

Shed Light

Since 2018, pedestrians in many U.S. cities have been sharing sidewalk space with dockless shared e-scooters. The introduction of e-scooters has received pushback from pedestrians. Complaints reported in the media include e-scooters blocking walkways and sidewalks when parked illegally as well as safety concerns from pedestrians who do not feel safe around moving e-scooters. However, little is known beyond a few initial studies on e-scooter parking and anecdotes about pedestrian perceptions of e-scooter safety. Our case study from Rosslyn, Virginia, helps shed light on these two issues. First, we conducted a survey of 181 e-scooter riders and non-riders asking about their perceived safety around riders of e-scooters and experiences of sidewalks blocked by e-scooters. We found highly divergent responses about safety and sidewalk blocking perceptions from riders and non-riders. Second, we conducted an observational study of 606 parked e-scooters along three mixed-use corridors in Rosslyn to investigate the relationship between the built environment and e-scooter parking. We found that 16% of 606 observed e-scooters were not parked properly and 6% (36 e-scooters) were blocking pedestrian right-of-way. Moreover, our survey showed that e-scooter trips in Rosslyn replaced trips otherwise taken by Uber, Lyft, or a taxi (39%), foot (33%), bicycle (12%), bus (7%), or car (7%).
