Definition of glycol in English English dictionary
A thick, colourless liquid, C2H4(OH)2, of a sweetish taste, produced artificially from certain ethylene compounds and used as an antifreeze; ethylene glycol
Any of a class of organic compounds of the alcohol family in which two hydroxyl groups (OH; see functional group) are attached to different carbon atoms. The term is often used for the simplest of the class, ethylene glycol (1,2-ethanediol). Propylene glycol (1,2-propanediol), much like ethylene glycol but not toxic, is used extensively in foods, cosmetics, and oral hygiene products as a solvent, preservative, and moisture-retaining agent. Other important glycols include 1,3-butanediol and 1,4-butanediol, used as raw materials for plastics and other chemicals; 2-ethyl-1,3-hexanediol, an insect repellent; and 2-methyl-2-propyl-1,3-propanediol, the raw material of the tranquilizer meprobamate
A co-solvent, combined with water in aqueous (latex) systems to form the total thinner Various glycols perform various functions, however, they are generally valuable as brushing agents and for temperature stability (ethylene glycol is the chief ingredient in anti-freeze) Generically, CH2OHCH2OH General term for dihydric alcohols; ethylene glycol is the most simple of the glycols
Any one of the large class of diacid alcohols, of which glycol proper is the type
A thick, colorless liquid, C2H4(OH)2, of a sweetish taste, produced artificially from certain ethylene compounds
A thick, colourless liquid, C{2}H{4}(OH){2}, of a sweetish taste, produced artificially from certain ethylene compounds and used as an antifreeze; ethylene glycol
An organic compound, HO-CH2-CH2-OH, and the chemical structure at right. It is a clear, colorless liquid under normal conditions, and is widely used as a vehicle engine coolant due to its anti-freeze properties
A colorless syrupy alcohol, HOCHOH, used as an antifreeze in cooling and heating systems. Simplest member of the glycol family, also called 1,2-ethanediol (HOCH2CH2OH). It is a colourless, oily liquid with a mild odour and sweet taste. Widely used as an antifreeze in automobile cooling systems, it is also used in many other chemical processes. It and some of its derivatives are fairly toxic. Many dogs, cats, and wild animals are attracted by its sweetness and poisoned by drinking ethylene glycol antifreeze that has been carelessly discarded
Any of a family of colorless liquids with high molecular weight that are soluble in water and in many organic solvents and are used in detergents and as emulsifiers and plasticizers
(1,2-Propanediol; methyl glycol; C3H8O2; molecular weight 76 09 ) A hydroscopic, viscous liquid Slightly acrid taste Miscible with water, acetone, chloroform Soluble in ether Will dissolve many essential oils, but is immiscible with fixed oils It is a good solvent for rosin Under ordinary conditions propylene glycol is stable, but at high temps it tends to oxidize giving rise to products such as propionaldehyde, lactic acid, pyuric acid, and acetic acid LD50 in rates is 30grams/kg It is completely miscible with water and dissolves in many essential oils It is used as a solvent for oral and injectable drugs, and is also employed in cosmetics, lotions, and ointments, as well as in the humidification of tobacco products
An aliphatic alcohol serving as an humectant in skin products and a solvent for preservatives, essential oils, flavors and fragrances Also used in preparation of herbal extracts
a sweet colorless, viscous, hygroscopic liquid used as an antifreeze and in brake fluid and also as a humectant in cosmetics and personal care items although it can be absorbed through the skin with harmful effects
