A broad overview of the achievements and emerging areas in field Green Chemistry.
Abstract Introduction “Vaping” electronic cigarettes (e-cigarettes) is increasingly popular with youth, driven by the wide range of available flavors, often created using flavor aldehydes. The objective this study was to examine whether aldehydes remain stable in e-cigarette liquids or they undergo chemical reactions, forming novel species that may cause harm user. Methods Gas chromatography used determine concentrations and reaction products e-liquids vapor generated from a commercial...
Abstract Introduction Menthol, through its cooling and pleasant sensory effects, facilitates smoking tobacco product initiation, resulting in the high popularity of mint/menthol-flavored E-cigarettes. More recently, E-cigarette vendors started marketing synthetic agents as additives that impart a effect but lack characteristic minty odor. Knowledge about content coolants US-marketed products associated health risks is limited. Aims Methods E-liquid vendor sites were searched with terms...
Flavor aldehydes in e-cigarettes, including vanillin, ethyl vanillin (vanilla), and benzaldehyde (berry/fruit), rapidly undergo chemical reactions with the e-liquid solvents, propylene glycol, vegetable glycerol (PG/VG), to form adducts named flavor aldehyde PG/VG acetals that can efficiently transfer e-cigarette aerosol. The objective of this study was compare cytotoxic metabolic toxic effects their parent respiratory epithelial cells.Cell assays were carried out bronchial (BEAS-2B)...
Among the most active areas of chemistry research today is that carbon dioxide utilization: an area was viewed as futile and commercially impractical not so long ago due to energetic stability CO2 molecule. The breakthroughs largely began in earnest 1990s have accelerated now make up a diverse plentiful portfolio technological scientific advances commercialized technologies. Here, "The Tree" presented tool illustrate breadth potential products from utilization communicate these chemical...
New solid basic catalysts immobilised onto supported ionic liquid-like phases have been prepared, having suitable mechanical stability for their use the continuous-flow Henry reaction.
Background ‘Juul’ is the dominant US e-cigarette brand and was recently introduced to Canada, UK, France, Germany Italy, with several flavours available across countries. US/Canadian products are sold 5%, 3% 1.5% (Canada only) nicotine content, whereas European Union (EU) regulation limits content 1.7%. The differential raises question if flavour profiles Juul device power output differ between Methods ‘Mint’, ‘Vanilla’ ‘Mango’ e-liquids from all six countries were purchased in 2019 analysed...
Ni-promoted, highly selective electrochemical protocol to reductively cleave the benzylic C–O bond of α-O-4 lignin model compound benzyl phenyl ether (BPE) at room temperature and ambient pressure.
Phthalate plasticizers such as di(2-ethylhexyl) phthalate (DEHP) are being phased out of many consumer products because their endocrine disrupting properties and ubiquitous presence in the environment. The concerns raised from use phthalates have prompted consumers, government, industry to find alternative that safe, biodegradable, versatility for multiple commercial applications. We examined toxicogenomic profile mono(2-ethylhexyl) (MEHP, active metabolite DEHP), plasticizer diisononyl...
This study uses a bioassay and chemical analysis to determine the proportion of newly introduced “non-menthol” cigarette brands with sensory cooling effects, agents added, any other flavor additives after menthol bans.
The ubiquitous environmental presence of industrial plasticizers such as di(2-ethylhexyl) phthalate (DEHP) and the known health impact has created a need to develop truly green that (i) are nontoxic, (ii) rapidly biodegrade, (iii) produced from renewable feedstocks across their whole life cycle including synthesis. For example, linear succinate diesters have been shown provide similar or better plasticizing properties compared DEHP, excellent biodegradation kinetics, no toxicity concerns....
