Fatal poisoning with diethylene glycol in an unusual setting. “PropyleneGlycol-stickAndBall” By Karlhahn – Own work (Public Domain) via Commons Wikimedia. This means it absorbs water when exposed to the atmosphere. NIH 2018 Jun 11;8(18):180606. doi: 10.5696/2156-9614-8.18.180606. 3. 2019 Dec;15(4):649-652. doi: 10.1007/s12024-019-00123-4. Ethylene glycol is produced when a reaction takes place between the ethylene oxide and water. Not to be confused with Polyethylene glycol, Diethylene glycol, Propylene glycol, or Glycol. 1. Figure 1: 3D Ball and Stick Model for Ethylene Glycol. The molar mass of propylene glycol is about 76.1 g/mol. Only monoethylene and diethylene glycol show evidence of developmental toxicity. All EGs exert acute toxicity in a similar manner, characterized by CNS depression and metabolic acidosis in humans and rodents; the larger molecules being proportionally less acutely toxic on a strict mg/kg basis. The term glycol is used when there are two hydroxyl groups present in neighboring carbon atoms. Ethylene Glycol: IUPAC name for Ethylene glycol is Ethane-1,2-diol. Ethylene glycol compounds share acute toxicity modes of action. None of the compounds present developmental toxicity concerns at doses that do not also cause significant maternal toxicity, nor do any of the EGs cause adverse effects on fertility. Oxygenated Volatile Organic Compounds (Anti-freezing Agents) in Decorative Water-based Paints Marketed in Nigeria. However, it is very useful as a chemical and can be found in many household items such as detergents, cosmetics, etc. Diethylene glycol-induced toxicities show marked threshold dose response in rats. Species differences exist in the metabolism and distribution of toxic metabolites, particularly with the formation of glycolic acids and oxalates (OX) from EG and diethylene glycol (DEG); OX are not formed to a significant degree in higher ethylene glycols. Ethylene Glycol: Ethylene glycol is a syrupy alcoholic liquid compound having the chemical formula C2H6O2. But large amounts can be toxic. Propylene Glycol: Propylene Glycol is used as a solvent for intravenous, oral, and topical pharmaceutical preparations. They are alcoholic compounds due to the presence of –OH groups.  |  It is mainly used for two purposes, as a raw material in the manufacture of … The IUPAC name for this compound is Propane-1,2-diol. The amount of oxalate in the blood and kidneys of Sprague-Dawley rats doses with ethylene and diethylene glycol was quantitated. PubChem Compound Database, U.S. National Library of Medicine, Available here. These organic compounds have important applications depending on the chemical structure of the compound. Therefore, it is an alcoholic compound. Landry GM, Dunning CL, Abreo F, Latimer B, Orchard E, McMartin KE.

Diethylene glycol induced histologic changes within the kidneys without kidney oxalate deposition. However, advanced methods can be used to obtain pure isomer out of the racemic mixture. Propylene Glycol is a synthetic organic compound that has the chemical formula C3H8O2. At room temperature, it is a clear liquid. Corley RA, Wilson DM, Hard GC, Stebbins KE, Bartels MJ, Soelberg JJ, Dryzga MD, Gingell R, McMartin KE, Snellings WM. “ETHYLENE GLYCOL.” National Center for Biotechnology Information. Main differences between propylene glycol and ethylene glycol: Between the two ethylene glycol is a better heat transfer fluid than propylene glycol. However, it is a moderately toxic compound. Toxicity. Toxicol Appl Pharmacol. Ethylene glycol induced oxalate deposition within the kidney without significant histologic changes. 3. 2. Diethylene glycol has moderate acute toxicity in animal experiments. Home » Science » Chemistry » Organic Chemistry » Difference Between Ethylene Glycol and Propylene Glycol. Ethylene glycol is a toxic compound. What is Propylene Glycol      – Definition, Applications 3. Their molecular formulas are different; thus they have some different physical properties. Propylene glycol has a very low toxicity, which is why it is also found in cosmetics and personal care products, whereas ethylene glycol is poisonous and must be handled with caution to … 1. Propylene Glycol: Propylene glycol is moderately toxic. Maximal kidney oxalate levels, following ethylene glycol dosage, occurred concurrently with peak blood oxalate concentrations. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Propylene glycol is hygroscopic. All of the EGs are quickly and extensively absorbed following ingestion and inhalation, but not by the dermal route. Clipboard, Search History, and several other advanced features are temporarily unavailable. Epub 2019 Jul 1. 2010 Dec;48(10):967-73. doi: 10.3109/15563650.2010.532803. Delayed neurological sequelae from ethylene glycol, diethylene glycol and methanol poisonings.
