Ethylene Glycol

Ethylene Glycol is a synonym for Ethanediol, a sweet, syrupy liquid which is widely used in antifreeze and as a solvent. Ethylene Glycol is Toxic and its sweet taste is believed to be a major fact in contributing to its potential danger to children and animals. When used in antifreeze, Ethylene Glycol is often coloured to alert persons to its potential danger.

Ethylene Glycol has a lower freezing point than that of water, which makes it effective as an ingredient in de-icers and as antifreeze. It is also used in air conditioning systems and as a precursor in the manufacture of polymers and resins.

More than 60% of the Ethylene Glycol produced worldwide is used for antifreeze whilst the rest is used as a polymer precursor. There are additionally many niche applications for Ethylene Glycol. It is used as an additive to present corrosion in liquid cooling systems and it is also used as a preservative and fungal treatment for wood. It is used in the manufacture of inks, dyes and shoe polish. It is also used in the manufacture of some vaccines.

The most hazardous aspect of Ethylene Glycol is its sweet taste and ingestion of Ethylene Glycol can be fatal, affecting the central nervous system, the heart and the kidneys. It is essential that Ethylene Glycol is stores safely, away from children and animals, in tightly closed containers. Ethylene Glycol is known as 'hygroscopic' meaning that it absorbs moisture from the air. Containers of Ethylene Glycol should be kept in a cool, well-ventilated area, away from incompatible materials such as oxidizing agents, acids and alkalis.

Personal protective Equipment should always be worn when working with or handling Ethylene Glycol, including approved safety glasses or goggles, safety footwear, protective overalls and appropriate safety gloves. Gas, fumes, vapour and spray should never be inhaled and large quantities should always be handled under fume extraction. Keep away from sources of ignition and keep away from heat.

If ingested seek medical attention immediately. Persons with pre-existing medical conditions may have greater sensitivity to Ethylene Glycol and particular attention should be paid to anyone suffering from respiratory, neurological or kidney disorders. Ethylene Glycol has a chemical formula of HOCH2CH2OH and synonyms include Glycol Alcohol, 1,2-Ethanediol and Ethylene Dihydrate.
