propylene glycol properties

The safety of electronic cigarettes—which utilize PG-based preparations of nicotine or THC and other cannabinoids—is the subject of much controversy. Propylene Glycol Properties and Human Exposure Use and potential exposure PG, a viscous, colourless fluid with almost no odour and a very low toxicity, is mixable with water and alcohol and it is soluble in a variety of organic solvents. Propylene Glycol 95.5 94.0 Inhibitors & Water 4.5 6.0 Color Water White Fluorescent Yellow Specific Gravity (at 60/60°F) 1.046 – 1.056 1.053 – 1.063 pH of Solution (50% glycol) 9.5 – 10.5 9.0 – 10.7 Reserve Alkalinity (min.) Propylene glycol Compound Information and Applications for GC (Gas Chromatography) and LC (Liquid Chromatography) Analysis Find another compound: Propylene glycol CAS # 57-55-6. About us. CAS: 57-55-6. Chemical and physical properties of Propylene Glycol. Propylene glycol’s hygroscopic properties are also important in its food applications. It is highly hygroscopic and miscible in all ratios with water, alcohols, esters, ketones and amines. Poly(ether)cyclicpolyols . 9.0 ml 16.0 ml †Typical properties, not to be construed as specifications. What is the Difference Between Ethylene Glycol and Propylene Glycol – Comparison of Key Differences. There is also animal evidence that it has mutagenic properties, meaning it can lead to cancer, and that it is a teratogen, meaning it causes birth defects. Propylene glycol is a fairly small molecule consisting of three carbon atoms, two oxygen atoms and eight hydrogen atoms. In particular, propylene glycol causes damage to the central nervous system, which includes the brain and spinal cord. While large dose inhalation is rare due to the low volatility of propylene glycol, if heated and inhaled it can cause respiratory irritation and central nervous system disruption. What kind of products contain propylene glycol? Mono propylene glycol also known as propylene glycol, PG, propan1, 2diol, MPG is a clear, colourless, and viscous liquid with a characteristic odour and the molecular formula C3H8O2, CAS: 57-55-6. A significant and important chemical property of propylene glycol is that when it mixes with water, it disturbs the formation of ice, which leads to its antifreeze utility. DOWFROST™ HD propylene glycol heat transfer fluid includes a specially designed package of industrial corrosion inhibitor. Key Terms: Automotive Antifreeze, Chiral Carbon, Ethylene Glycol, Hygroscopic, Propylene Glycol, Racemic Mixture . The antimicrobial properties of three glycols, - propylene glycol, hexylene glycol, and 1,3-butylene glycol - against Candida albicans, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes A, Streptococcus mitis, and E. coli were studied in vitro. Propylene glycol is an ingredient in many food products, medicine, supplements, and other edible items like liquid sweeteners. EC Number 210-817-6. Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol commonly used in paints and cleaners. Propylene glycol did not have any effects on reproductive or behavioral development parameters. a viscous, stable, hygroscopic liquid. Propylene glycol works as a humectant by attracting moisture to the skin, and consequently hydrating and moisturizing it. Propylene glycol has humectant properties, meaning it draws water into your skin. Pro­­­­­­­py­­­­­­­lene Glycol wirkt hygros­­­­ko­­­­pisch, zieht also Wasser an und bindet es. Propylene glycol is used as antifreeze in breweries and diaries, in the manufacture of resins, as a solvent, and as an emulsifier in food. +Add Attachment Density of propylene glycol + water mixtures at 293.15, 298.15, 303.15, 318.15, and 323.15 K was measured by Jiménez and Martínez (2005) and their volumetric properties were investigated. Propylene Glycol 56-55-6 200-338-0 >99.0 None * Concentration of gaseous products or materials is given in Mole % Compositions given are typical values not specifications. Propylene glycol is practically odorless and tasteless. For information refer to the Emergency Overview in Section 3 of this … It is a clear, colorelss, viscous liquid, slightly bitter-tasting. Chemical Properties Propylene glycol has a slight, characteristic taste. The resulting compounds have toxicological properties that differ from either the flavorants or solvent compone … Formation of flavorant-propylene Glycol Adducts With Novel Toxicological Properties in Chemically Unstable E-Cigarette Liquids Nicotine Tob Res. It is soluble in water, and has hygroscopic properties. 4. Specific heat of propylene glycol solutions: 1 Btu/ (lbmoF) = 4186.8 J/ (kg K) = 1 kcal/ (kgoC) Empirical Formula (Hill Notation): C10H12O2. By attracting and holding water-based and oil-based substances, PG is able to provide homogenous distribution in a mixture. Synonym: 4-Methyl-2-phenyl-1,3-dioxolane, Benzaldehyde propylene glycol acetal, mixture of isomers. propylene glycol are $0.22, $0.50, and $1.00 per pound respectively, the net present value (NPV) at the end of the 15 year allotted course of the project is $88.4 million and the investors’ rate of return (IRR) is 58.45%. Propylene glycol was used as a vehicle in a reproductive and behavioral development study. Chemical Properties of Propylene … CAS Number: 2568-25-4. Its molecular weight is 76.09 g/mol, according to the CRC Handbook of Chemistry and Physics.
