Ethylene glycol is a colorless, odorless, sweet liquid, commonly found in antifreeze. [1] It may be drunk accidentally or intentionally in a suicide attempt. [2] When broken down by the body it results in glycolic acid and oxalic acid which cause most of the toxicity.
Antifreeze products for automotive use containing propylene glycol in place of ethylene glycol are available. They are generally considered safer to use, as propylene glycol is not as palatable [ note 1 ] and is converted in the body to lactic acid , a normal product of metabolism and exercise.
An antifreeze is an additive which lowers the freezing point of a water-based liquid. An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [ 1 ]
Glycerol was historically used as an anti-freeze for automotive applications before being replaced by ethylene glycol, which has a lower freezing point. While the minimum freezing point of a glycerol-water mixture is higher than an ethylene glycol-water mixture, glycerol is not toxic and is being re-examined for use in automotive applications.
A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes.
An aerosol frostbite of the skin is an injury to the body caused by the pressurized gas within an aerosol spray cooling quickly, with the sudden drop in temperature sufficient to cause frostbite to the applied area. [1] Medical studies have noted an increase of this practice, known as "frosting", in pediatric and teenage patients. [2] [3]
Vibration: the body is disintegrated into particles within minutes Freeze drying: particles are freeze dried in a drying chamber, leaving approximately 30% of the original weight Metal separation: any metals (e.g., tooth amalgam , artificial hips , etc.) are removed, either by magnetism or by sieving .
Flammable applies to combustible materials that ignite easily and thus are more dangerous and more highly regulated. Less easily ignited less-vigorously burning materials are combustible . For example, in the United States flammable liquids , by definition, have a flash point below 100 °F (38 °C)—where combustible liquids have a flash point ...
