  ATSDR - MMG: Ethylene Glycol
Ethylene glycol is produced commercially in large amounts and widely used as an antifreeze and de-icer.
Ethylene glycol is a dehydrating agent and is mildly irritating to the skin and mucous membranes after prolonged contact.
Ethylene glycol is a mild respiratory tract irritant.

 [No title]
Ethylene glycol is a federal hazardous air pollutant and was identified as a toxic air contaminant in April 1993 under AB 2728.
Ethylene glycol is slightly soluble in ether and practically insoluble in benzene and its homologs, chlorinated hydrocarbons, petroleum ether, and oils (Merck, 1989).
Ethylene glycol is used as an antifreeze, as a heat transfer agent, in polyester fiber and film manufacture, as a deicer, and as a solvent (HSDB, 1991).

 Ethylene Glycol and Propylene Glycol: Health Information Summary
Releases of ethylene glycol to the environment are widespread, with the major source being the disposal of used antifreeze and de-icing solutions and, secondarily, by industry during its production.
As a comparison of acute toxicity in animals, the dose of ethylene glycol that was lethal to 50 percent of rats ranged from 4,000-9,000 parts per million (ppm) of body weight compared to 8,000-46,000 ppm in rats given propylene glycol.
Because neither ethylene glycol nor propylene glycol has undergone a comprehensive evaluation of its carcinogenic potential, they would both be classified as Group D carcinogens, "inadequate evidence to classify," under the old U.S. Environmental Protection Agency (EPA) cancer guidelines and "inadequate information to assess carcinogenic potential" under the new guidelines.

 Ethylene glycol intoxication
Ethylene glycol may be ingested accidentally, or it may be consumed deliberately in a suicide attempt or as a substitute for drinking alcohol (ethanol).
Ethylene glycol toxicity results when enzymes in the liver metabolize (break down) ethylene glycol into smaller compounds, which deposit in body tissue and cause damage.
Ethylene glycol toxicity should be suspected in anyone who is severely ill after drinking an unknown substance, especially if they initially appear drunk without the characteristic breath odor of drinking alcohol (ethanol).

 eMedicine - Toxicity, Ethylene Glycol : Article by Daniel C Keyes, MD, MPH
Ethylene glycol is a relatively common cause of overdose in American emergency departments.
Although the parent compound, ethylene glycol, may cause some alteration of mental status, it is a relatively nontoxic compound before it is metabolized.
Serum osmolality: Because ethylene glycol levels are not reported in a clinically helpful fashion in most institutions, ethylene glycol exposure level is often estimated through measurement of the serum osmolality.

 Ethylene Glycol | Technology Transfer Network Air Toxics Web site | US EPA
Ethylene glycol has many uses, including as antifreeze in cooling and heating systems, in hydraulic brake fluids, and as a solvent.
Acute animal tests in rats, mice, rabbits, and guinea pigs have demonstrated ethylene glycol to have moderate acute toxicity by inhalation or dermal exposure and low to moderate acute toxicity by ingestion.
Ethylene glycol occurs as a clear, slightly viscous liquid that is completely miscible with water.

 Ethylene Glycol
In an ethylene glycol poisoning, once crystals are found in the urine, kidney damage has already begun.
Before or after that time period, a false negative test result may be obtained since either the ethylene glycol has not yet entered the bloodstream, or it has already been broken down into its metabolites.
Cats: 0.64 ml per pound of body weight (1 teaspoon of ethylene glycol diluted 50:50 with water in radiator fluid is toxic to the average-sized cat).

 Ethylene Glycol Monobutyl Etehr, Butyl Glycol, Butyl Cellosolve, , 2-Butoxy Ethanol
Ethylene Glycol Monobutyl Ether is chemically known as a Butyl Glycol, 1-n-Butoxy-2-hydroxyethane, n-butyl (2-hydroxyethyl) ether.
Small quantities of Ethylene Glycol Monobutyl Ether improves both the flow and dilution capacity of the lacquers and also enhance the gloss of the resultant lacquer films.
Since Butyl Glycol (2-Butoxy Ethanol) dries lacquer coatings very slowly, it is ideal for the preparation of brushing lacquers based on cellulose esters, cellulose ethers and chlorinated rubber.

 Brake Fluid, Antifreeze Coolant :: Advance Petrochemicals Ltd ::
Therefore, 100% water has spoiled the coolant system due to corrosion and scale.
The evaporation rate of water is higher in comparison with Glycols so the topping and the addition of water is required many times than other materials and each time it leaves a more scale in the system.
The distilled and demineralise water have own their problems like affinity to the Aluminium metal etc. The Freezing point of water is 0º C and in the world there are so many regions where the temperature goes below 0º C in winter and the water is freezed in vehicles and became non- operative.
