Ethylene glycol is rapidly absorbed from the gastrointestinal tract and slowly absorbed through the skin or lungs. Ethylene glycol may be swallowed accidentally, or it may be taken deliberately in a suicide attempt or as a substitute for drinking alcohol (ethanol). Ethylene Glycol based water solutions are common in heat-transfer applications where the temperature in the heat transfer fluid can be below 32 o F (0 o C).Ethylene glycol is also commonly used in heating applications that temporarily may not be operated (cold) in surroundings with freezing conditions - such as cars and machines with water cooled engines. Polyethylene glycol (PEG) is a biocompatible, synthetic, hydrophilic polyether compound that has many applications, mostly in the medical industry, but also in the chemical and industrial sectors. Ethylene glycol is metabolized in the liver to a variety of more toxic compounds. Ethylene glycol is a colorless liquid with the chemical formula C2H6O2. Reference: 1. Antifreeze. Immediate steps should be taken to limit its spread to the environment. Diethylene Glycol is produced as a co-product of Ethylene Glycol and Triethylene Glycol. Diethylene glycol, or DEG, is a colorless, liquid organic compound at room temperature produced by the interaction of ethylene glycol and triethylene glycol. Polyethylene glycol 3350 is a laxative solution that increases the amount of water in the intestinal tract to stimulate bowel movements. The hydroxyl groups on glycols undergo the usual alcohol chemistry, giving a wide variety of possible derivatives. Ethylene glycol is rapidly absorbed from the gastrointestinal tract and slowly absorbed through the skin or lungs. Ethylene Glycol: Ethylene glycol is mainly used in antifreeze formulations and as a raw material in the manufacturing of polyesters such as polyethylene terephthalate (PET) in plastic industry. It is a colorless, practically odorless, poisonous, hygroscopic liquid with a sweetish taste. Mono Ethylene Glycol is used as solvent couplers, chemical intermediates for resins, and humectants. It is slightly viscous in nature and shows miscibility with alcohols, water, and aldehydes. The primary hazard is the threat to the environment. In untreated adults, approximately 20% of a dose of ethylene glycol is excreted unchanged by the kidneys. EG is useful as a raw material in the production of several products. It is used to make polyester and to make antifreeze. Diethylene glycol (DEG) is an organic compound with the formula (HOCH 2 CH 2) 2 O. Ethylene glycol antifreeze is the most common antifreeze used in automotive applications worldwide. Ethylene glycol is chemically broken down in the body into toxic compounds.
