which contains information on oral chronic toxicity and the RfD, and the carcinogenic effects of ethylene glycol, and the Agency for Toxic Substances and Disease Registry's Toxicological Profile for Ethylene Glycol and Propylene Glycol. They easily penetrate the skin and can weaken protein and cellular structure. It is the most commonly available glycol and is commercially produced in large quantities. Propylene glycol poisoning in dogs is caused by ingesting propylene glycol. Ethylene glycol poisoning can be lethal, but if treated within the hour is much less likely to cause death. Pentylene glycol does not have any evidence to suggest toxicity or carcinogenicity. In cats, ingestion of a diet containing 6%–12% PG can result in Heinz … After a characteristic latent period, signs of inebriation may be followed by serious illness, and even death, caused by toxic metabolites. > “Propylene glycol is one of the least toxic glycols," says veterinary toxicologist Ahna Brutlag, DVM, MS, DABT, DABVT, associate director of veterinary services for Pet Poison Helpline. ANSWER: In contrast to ethylene glycol, a potent cause of acute toxicity in humans, propylene glycol is a “generally recognized as safe” (GRAS) additive for foods and medications. Propylene glycol is a synthetic substance with a myriad of uses in the industrial, pharmaceutical, food, and cosmetics industries. Ethanol and fomepizole are effective; fomepizole is preferred. “They’re so dangerous workers need lots of protection to handle them” A few places warn that workers need to wear special equipment when handling these chemicals. Ethylene glycol is a colorless, odorless, sweet-tasting chemical. Now, moving on to ethylene glycol’s less toxic cousin, propylene glycol. Propylene glycol is considerably less toxic than ethylene glycol. Butylene glycol is a conditioning agent. Although less toxic than EG, ingestion of propylene glycol (PG) may be associated with a toxic syndrome similar to the acute phase of EG toxicosis. Is propylene glycol the same as antifreeze? It is a synthetic liquid substance that absorbs water and is used by the chemical, food, and pharmaceutical industries for a wide variety of reasons. Sunny Z. Hussain. Uses. It can actually be labelled ‘non-toxic’. Ethylene glycol and some of its derivatives are mildly toxic. Ethylene glycol may be swallowed accidentally, or it may be taken deliberately in a suicide attempt or as a substitute for drinking alcohol (ethanol). Propylene glycol can only be toxic if used intravenously at high dosage or when applied to compromised skin causing burns. "It is a synthetic liquid substance that absorbs water and is used by the chemical, food and pharmaceutical industries for a wide variety of reasons." Ethylene glycol toxicity is a type of toxic leukoencephalopathy.Ethylene glycol, best known as a component of antifreeze, has been ingested both deliberately and accidentally, resulting in … Propylene Glycol vs. Propylene glycol (PG) is one of the least toxic glycols. Polyethylene glycol is derived from petroleum and is made from ethylene glycol. According to Herrmann, ethylene glycol (an ingredient used in antifreeze) is considered to be toxic and harmful, while propylene glycol is not. French chemist Charles-Adolphe Wurtz first synthesized ethylene glycol in 1859 from potassium hydroxide using a saponification process similar to that used to produce commercial soaps. Propylene glycol, also called 1,2-propanediol, resembles ethylene glycol in its physical properties. This should make consumers a little uncomfortable. Probable neuropsychiatric toxicity of polyethylene glycol: roles of media, internet and the caregivers. It and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally … Ethylene Glycol Though commonly confused for each other, propylene glycol and ethylene glycol are structurally different, and it's important to distinguish the two. It is poisonous if swallowed. Ethylene Glycol: The molecular weight of ethylene glycol is about 62.07 g/mol. The alleged exposure may be erroneous. Propylene glycol rarely causes toxic effects, and then only under very unusual circumstances. Polyethylene glycol (PEG) has many applications […] Ethylene glycol has a sweet taste and is often accidentally or intentionally ingested. It has many industrial applications; it is used as an antifreeze coolant in hydraulic fluids and in the manufacturing of low-freezing dynamites and resins. Ethylene glycol is chemically broken down in the body into toxic compounds. Ethylene Glycol: Ethylene glycol is mainly used for the manufacturing of polyester fibers and as an automotive antifreeze. Ethylene glycol is widely used as antifreeze in automobile cooling systems and in the manufacture of human-made fibres, low-freezing explosives, and brake fluid. They report that in adults, 45% of propylene glycol is eliminated by the kidneys and 55% by the liver, where it gets converted to lactic acid, pyruvic acid, or acetone. Most intoxications are associated with ingestion of antifreeze, which is typically 95% EG. Jaime Belkind‐Gerson. Propylene glycol is a common ingredient in antifreeze, lubricants, and products of plasticity. It will correct metabolic acidosis, and reduce both ethylene glycol levels and the toxic EG metabolites.
