Ethyl alcohol 99.9° available in cubes, drums or bulk. It has applications in the spirits industry, as a solvent for perfumery; in the pharmaceutical industry it is used for synthesis and as a solvent.
Ethanol 99.9% Absolute
Anhydrous ethanol is absolute ethanol, also referred to as pure ethanol.
70% isopropyl alcohol is by far better at killing bacteria and viruses than 99% isopropyl alcohol. As a disinfectant, 70% concentration of alcohol is the most effective at killing pathogens. Any higher or lower percentage will be less effective.
Absolute ethanol finds use in a variety of applications, including medical, organic chemistry, and biology. It is also used as an alternative fuel source to gasoline for combustion engines.
Ethanol is used in alcoholic beverages, as a food flavoring, a fuel additive, a solvent, in pharmaceuticals/medicines (rubbing compounds, liquid medicines and lotions), in perfumes/colognes, in the manufacture of denatured alcohol, and is also used to make other chemicals (organic synthesis).
Under no circumstances is rubbing alcohol intended for consumption. It is not a substitute for alcohol, wine or beer. It is toxic.
In adults severe symptoms of ethanol intoxication may develop after ingestion of 1 to 1.5 mL/kg (50-100 mL) of pure ethanol. Death is usually associated with levels >80 to 90 mmol/L, but the lethal level may be much higher for chronic ethanol users. 1.
Alcohols are organic molecules assembled from carbon (C), oxygen (O), and hydrogen (H) atoms. When 2 carbons are present, the alcohol is called ethanol (also known as ethyl alcohol). Ethanol is the form of alcohol contained in beverages including beer, wine, and liquor.
In purely scientific terms, alcohol is the name for a whole range of molecules that are formed when oxygen and hydrogen atoms bind with an atom of carbon. But when it comes to alcoholic drinks, all of the alcohol is a specific small molecule called ethanol – and if affects your body every time you drink.
95% reagent ethanol is mainly used as analytical solvent. It is also used as disinfectant in many lab applications when diluted to 70%. Note: AR: Analitycal Reagent Grade: Reagents for analytical purpose or research work that need high purity.
Stronger Isn't Always Better
Even though you may think the higher concentration is more effective, experts say 70% is actually better for disinfecting. It has more water, which helps it to dissolve more slowly, penetrate cells, and kill bacteria.
The difference is that 99% is a significantly higher fire hazard. That's correct - the only real difference is in fire hazard.
Because 70% ethanol is bactericidal. This concentration of ethanol able to kill most of the microbes in short time. Quite simply, 70% empirically was determined to be the most effective. "70% ethanol is the minimum concentration when used in a lab setting for aseptic technique.
Cargill's 99.9% Pharmaceutical Agricultural Alcohol is a product of agricultural origin, highly purified, and with a characteristic odour. This natural product is produced by fermentation of the sugars, using yeast. The sugars are derived mainly from molasses and grain.
The EPA enforces a summertime ban on E15 over concerns it contributes to smog in hot weather, though research has since shown E15 blend may not increase smog relative to the more common E10 sold year-round.
Vodka, as defined by U.S. law, is diluted ethyl alcohol or Ethanol. To be designated as vodka, the liquid must contain a minimum of 40% (ethyl alcohol) by volume. The rest is essentially water. Vodka can be made from virtually any product that can be fermented and distilled to produce high-proof alcohol.
While ethanol is consumed when drinking alcoholic beverages, consuming ethanol alone can cause coma and death.
Ethanol (CH3CH2OH) is a clear, colorless liquid. It is also known as ethyl alcohol, grain alcohol, and EtOH (see Fuel Properties search.)
The four types of alcohol are ethyl, denatured, isopropyl and rubbing. The one that we know and love the best is ethyl alcohol, also called ethanol or grain alcohol.
Distilled spirits (whisky, gin, vodka) usually contain 40–50% ethanol; wines contain 10–12% ethanol and beer ranges from 2–6% ethanol, while standard lager contains about 4% ethanol. Numerous over-the-counter medicinal or cosmetic products can also contain significant percentages of ethanol (10–40%).
Does alcohol kills germs and viruses? Isopropyl alcohol is effective against viruses such as FCV at 40% – 60% concentrations. Ethanol however, is more effective at 70% – 90% concentrations against FCV. Contact time indicates how effective an alcohol is against a target microbe in a given period of time.
exposure can cause drying and cracking of the skin with peeling, redness and itching. lungs. ► Exposure to Ethyl Alcohol can cause headache, drowsiness, nausea and vomiting, and unconsciousness.
95% ethanol, undenatured ethyl alcohol is a potable ethanol suitable for applications where the higher odour or presence of other denaturants makes conventional methylated spirits unsuitable.
Ethanol level can be measured by blood, urine, saliva, or breath tests. Toxic concentration is dependent on individual tolerance and usage although levels greater than 300-400 mg/dL can be fatal due to respiratory depression.
