Ethylene glycol (EG, 1,2-ethanediol) is a two-carbon dihydroxy alcohol that can be derived from fermentation of plant-derived xylose and arabinose and which can be formed during food fermentations. Here we show that Propionibacterium freudenreichii DSM 20271 is able to convert EG in anaerobic ...

Some common compounds found in e-cigarettes include propylene glycol and vegetable glycerin (which are used as solvents), flavourings, nickel (an allergen), diacetyl (a flavouring agent linked to lung disease), nitrosamines (carcinogens), formaldehyde (a carcinogen) and lead (a neurotoxin). Many ...
volatile silicone which is not an elastomer; 0.1-5 weight % of a silicone copolyol surfactant; and 0-20 weight % of a nonvolatile silicone which is not an elastomer; wherein the composition is free of (1) C1-5 saturated alcohols, (2) added propylene glycol, (3) elastomer gelling ...

BHT is insoluble in water, 10NaOH solution, glycerol, and propylene glycol. BHT is odorless, odorless with good thermal stability.BHT, also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties....
(nD20) is 1.5670, and its relative density (d435) is 1.0700. It is soluble in ethanol (1ml in 4mL of 80% ethanol), ether, glycerol, propylene glycol, most non-volatile oils, and mineral oil, but insoluble in water. It naturally occurs in essential oils such as basil oil (up to ...
Consequently, the investigations of e-cigarettes vapors should always consider carbonyls and volatile compounds monitoring. Although concerns about the generation of contaminants from glycerin and propylene glycol are well identified, other concerns that have received little attention until now include the ...
The domestic PC market is weak and volatile. In the middle of the week, the domestic PC factory has no latest price adjustment news for the time being. It is heard that the latest external price quotation of an imported material is around US $1950/ton. The industry's intention to return...
(CSEO) as well as their particular anti-bacterial mode of action. The volatile elements had been characterized utilizing gasoline chromatography coupled to a mass spectrometer (GC-MS). The outcome unveiled remarkable anti-bacterial properties of EO produced from C. sempervirens. GC-MS evaluation ...
