Query: What is the chemical compound of rubbing alcohol?
Isopropyl alcohol (IUPAC name propan-2-ol; commonly called isopropanol) is a compound with the chemical formula CH3CHOHCH3. It is a colorless, flammable chemical compound with a strong odor. As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of 1-propanol and ethyl methyl ether.
Product labels for rubbing alcohol include a number of warnings about the chemical, including the flammability hazards and its intended use only as a topical antiseptic and not for internal wounds or consumption. It should be used in a well-ventilated area due to inhalation hazards. Poisoning can occur from ingestion, inhalation, absorption, or consumption of rubbing alcohol.
Whereas alcohol is intrinsically a denaturing and inert rendering agent to many of a botanical's extracted constituent and compounds, glycerin possesses no such denaturing and inert rendering effects on a botanical's extracted constituents and compounds. From both clinical and manufacturing perspectives, this is possibly the most important defining differentiator between alcohol-based made tinctures versus 'true' alcohol-free glycerin-based made Glycerites, that includes: 'actual' levels or degrees of efficacy relative to actual concentrations (i.e. percentages) of constituents and/or constituent group(s) present in a finished tincture and/or Glycerite, now given what has previously been unaddressed concerning the denaturing/inert-rendering weighted factor for alcohol-based tinctures (a Clinical consideration); and the QA/QC related physical properties inherent in and chemically intrinsic to a finished tincture and/or Glycerite as regards inverting, REDOX, precipitation, scaling, novel constituent complexing, etc. (a Manufacturing consideration).
Rubbing alcohol refers to either isopropyl alcohol (propan-2-ol) or ethanol based liquids, or the comparable British Pharmacopoeia defined surgical spirit, with isopropyl alcohol products being the most widely available. Rubbing alcohol is undrinkable even if it is ethanol based, due to the bitterants added.
The book defines an element as a single substance that can't be broken down by chemical analysis and from which all chemical compounds are formed, publishing his discovery that fermentation produces carbon dioxide (carbonic gas) and spirit of wine, saying that it is "more appropriately called by the Arabic word alcohol since it is formed from cider or fermented sugar as well as wine", and publishing the first chemical equation "grape must = carbonic acid + alcohol", calling this reaction "one of the most extraordinary in chemistry", noting "In these experiments, we have to assume that there is a true balance or equation between the elements of the compounds with which we start and those obtained at the end of the reaction."
Liniments are typically sold to relieve pain and stiffness, such as from sore muscular aches and strains, or arthritis. These are typically formulated from alcohol, acetone, or similar quickly evaporating solvents and contain counterirritant aromatic chemical compounds such as methyl salicilate, benzoin resin, menthol, or capsaicin. They produce a feeling of warmth within the muscle of the area they are applied to, typically acting as rubefacients via a counterirritant effect.
The methyl salicylate that is the active analgesic ingredient in some heat-rub products can be toxic if they are used in excess. Heating pads are also not recommended for use with heat rubs, as the added warmth may cause overabsorption of the active ingredients.Liniments are commonly used on horses following exercise, applied either by rubbing on full-strength, especially on the legs; or applied in a diluted form, usually added to a bucket of water and sponged on the body. They are used in hot weather to help cool down a horse after working, the alcohol cooling through rapid evaporation, and counterirritant oils dilating capillaries in the skin, increasing the amount of blood releasing heat from the body.
2-Pentanol (IUPAC name: pentan-2-ol; also called "sec"-amyl alcohol) is an organic chemical compound. It is used as a solvent and an intermediate in the manufacture of other chemicals. 2-Pentanol is a component of many mixtures of amyl alcohols sold industrially.
Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is a chemical compound, a simple alcohol with the chemical formula . Its formula can be also written as −− or − (an ethyl group linked to a hydroxyl group), and is often abbreviated as EtOH. Ethanol is a volatile, flammable, colorless liquid with a slight characteristic odor. It is a psychoactive substance and is the principal type of alcohol found in alcoholic drinks.
Garlic dermatitis is similar to the tulip dermatitis and is induced by a combined mechanical and chemical action. Whereas the former mechanism acts via skin rubbing which progresses into damage, the major cause of the latter is the chemical diallyl disulfide (DADS), together with related compounds allyl propyl disulfide and allicin. These chemicals occur in oils of plants of the genus "Allium", including garlic, onion and leek.
The tarsal gland appears to operate by a different mechanism than the other external scent glands. A behavior called "rub-urination" is central to this mechanism. During rub-urination, the animal squats while urinating so that urine will run down the insides of its legs and onto its tarsal glands. The tarsal glands have a tuft of hair which is specially adapted to extract certain chemical compounds from the animal's urine. For example, in the black-tailed deer ("Odocoileus hemionus columbianus"), the major constituent of the tarsal gland secretion is a lipid, (Z)-6-dodecen-4-olide. This compound does not originate in the tarsal gland itself, but rather it is extracted from the animal’s urine by the tarsal hair tuft during the rub-urination process. In white-tailed deer, the presence and concentration of certain chemical compounds in the urine depend on the season, gender, reproductive status and social rank of the animals. This fact, along with the observation of rub-urination behavior in this animal (at least in the male) indicates that urine probably plays a role in olfactory communication in deer.
Alcohol rub sanitizers kill most bacteria, and fungi, and stop some viruses. Alcohol rub sanitizers containing at least 70% alcohol (mainly ethyl alcohol) kill 99.9% of the bacteria on hands 30 seconds after application and 99.99% to 99.999% in one minute.

The term "rubbing alcohol" came into prominence in North America in the mid-1920s. The "original" rubbing alcohol was literally used as a liniment for massage; hence the name. This original rubbing alcohol was rather different from today's precisely formulated surgical spirit; in some formulations it was perfumed and included different additives, notably a higher concentration of methyl salicylate.
The United States Pharmacopeia defines 'isopropyl rubbing alcohol USP' as containing approximately 70 percent by volume of pure isopropyl alcohol and
defines 'rubbing alcohol USP' as containing approximately 70 percent by volume of denatured alcohol. In Ireland and the UK, the comparable preparation is surgical spirit B.P., which the British Pharmacopoeia defines as 95% methylated spirit, 2.5% castor oil, 2% diethyl phthalate, and 0.5% methyl salicylate.
Under its alternative name of "wintergreen oil", methyl salicylate is a common additive to North American rubbing alcohol products. Individual manufacturers are permitted to use their own formulation standards in which the ethanol content for retail bottles of rubbing alcohol is labeled as and ranges from 70-99% v/v.
Anisyl alcohol (4-methoxybenzyl alcohol) is an organic compound with the chemical formula CHOCHCHOH. It is a colorless liquid that is used as a fragrance and flavorant. It occurs naturally but is produced by reduction of anisaldehyde.
Alcohol-based hand rubs are extensively used in the hospital environment as an alternative to antiseptic soaps. Hand-rubs in the hospital environment have two applications: hygienic hand rubbing and surgical hand disinfection. Alcohol based hand rubs provide a better skin tolerance as compared to antiseptic soap.
Hand rubs also prove to have more effective microbiological properties as compared to antiseptic soaps.
Comparing hand-rubbing with alcohol-based solution with hand washing with antibacterial soap for a median time of 30 seconds each showed that the alcohol hand-rubbing reduced bacterial contamination 26% more than the antibacterial soap. But soap and water is more effective than alcohol-based hand rubs for reducing H1N1 influenza A virus and Clostridium difficile spores from hands.
All rubbing alcohols are unsafe for human consumption: isopropyl rubbing alcohols do not contain the ethyl alcohol of alcoholic beverages; ethyl rubbing alcohols are based on denatured alcohol, which is a combination of ethyl alcohol and one or more bitter poisons that make the substance toxic.
Isopropyl alcohol is esterified to give isopropyl acetate, another solvent. It reacts with carbon disulfide and sodium hydroxide to give sodium isopropylxanthate, an herbicide and an ore flotation reagent.[20] Isopropyl alcohol reacts with titanium tetrachloride and aluminium metal to give titanium and aluminium isopropoxides, respectively, the former a catalyst, and the latter a chemical reagent.[15] This compound may serve as a chemical reagent in itself, by acting as a dihydrogen donor in transfer hydrogenation.
Methanol (also known as methyl alcohol, carbinol, wood alcohol, wood naphtha or wood spirits) is a chemical compound with chemical formula CHOH. It is the simplest alcohol, and is a light, volatile, colorless, flammable, poisonous liquid with a distinctive odor that is somewhat milder and sweeter than ethanol (ethyl alcohol). At room temperature, it is a polar solvent and is used as an antifreeze, solvent, fuel, and as a denaturant for ethyl alcohol. It is not popular for machinery, but may be found in automotive windshield washer fluid, de-icers, and gasoline additives.
Whiskies and other distilled beverages, such as cognac and rum, are complex beverages that contain a vast range of flavouring compounds, of which some 200 to 300 are easily detected by chemical analysis. The flavouring chemicals include "carbonyl compounds, alcohols, carboxylic acids and their esters, nitrogen- and sulphur-containing compounds, tannins, and other polyphenolic compounds, terpenes, and oxygen-containing, heterocyclic compounds" and esters of fatty acids. The nitrogen compounds include pyridines, picolines and pyrazines. The sulfur compounds include thiophenes and polysulfides which seem to contribute to whiskey's roasted character.
Isopropyl rubbing alcohols contain from 50% to 99% by volume of isopropyl alcohol, the remainder consisting of water. Boiling points vary with the proportion of isopropyl alcohol from to ; likewise freezing point vary from to . Surgical spirit BP boils at .
They are liquids used primarily as a topical antiseptic.
They also have many industrial and household uses. The term "rubbing alcohol" has become a general non-specific term for either isopropyl alcohol (isopropanol) or ethyl alcohol (ethanol) rubbing-alcohol products.
Diacetone alcohol is a chemical compound with the formula CHC(O)CHC(OH)(CH), sometimes called DAA. This liquid is a common synthetic intermediate used for the preparation of other compounds, and is also used as a solvent.
1-Tridecanol is a chemical compound from the group of alcohols (specifically, the fatty alcohols ). It is in the form of a colorless, flammable solid. 1-Tridecanol usually occurs as a mixture of different isomeric to compounds such as 2-tridecanol, 3-tridecanol, 4-tridecanol, 5-tridecanol, 6-tridecanol and isotridecanol.
