A boil test is a classic way to determine the efficacy of fuel. So for this guide I set about doing just that. When conducting the boil tests I certainly inhaled some fumes. When filling the alcohol stoves with fuel some of each fuel inevitably got on my fingers. It’s hard to avoid.

Isopropyl alcohol is esterified to give isopropyl acetate, another solvent. It reacts with carbon disulfide and sodium hydroxide to give sodium isopropylxanthate, a herbicide and an ore flotation reagent. [22] 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. [17] This compound may serve as a chemical reagent in itself, by acting as a dihydrogen donor in transfer hydrogenation. Lindblad, Adrienne J.; Ting, Rhonda; Harris, Kevin (August 2018).

While denatured alcohol can also be used as an effective cleaning agent, it cannot be used on skin as an antiseptic. The main reason for this is its toxicity. By containing methanol, denatured alcohol could cause dermatitis if skin is exposed to it. While IPA does have the propensity to be a skin irritant, this is only in circumstances where high concentrations have been left on the skin for long periods of time. Because denatured alcohol contains methanol, along with several other toxic chemicals which you may not be able it identify, it is generally unsafe to use as an antiseptic as it could cause severe reactions and even poisoning. Electronics This 99.9% IPA is both anhydrous, hydroscopic, and fully miscible with water, so it can be used to scavenge moisture and dehumidify surfaces. It also has a low surface tension, so it wets easily, making it an effective cleaner. Isopropyl alcohol (IUPAC name 2-propanol), also called isopropanol, is a compound with the chemical formula C3H8O or C3H7OH or CH3CHOHCH3. It is a colourless, flammable chemical compound with a strong odour. It is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms sometimes shown as (CH3)2CHOH. It is a structural isomer of propanol. It has a wide variety of industrial and household uses. Properties of IsopropanolBoth do, however, have disinfecting properties, can be poisonous, are colourless, are flammable and smell funny. a b c d e Slaughter RJ, Mason RW, Beasley DM, Vale JA, Schep LJ (2014).

As of this writing the safety data sheet (SDS) for another Crown product, Crown Denatured Alcohol, shows it has a potentially identical composition to Crown Alcohol Stove Fuel (I say “potentially” because it contains ranges as opposed to exact percentages). Isopropyl alcohol is also commonly called “rubbing alcohol.” Its molecular structure contains one more carbon and two more hydrogen molecules than ethyl alcohol. Its formula is written as C 3H 7OH. People can use rubbing alcohol that contains 70% isopropyl alcohol to disinfect minor cuts and scrapes. To do this, follow these steps:Isopropyl alcohol forms an azeotrope with water, which gives a boiling point of 80.37°C (176.67°F) and a composition of 87.7% by mass (91% by volume) isopropyl alcohol. Alcohol mixtures have depressed melting points. [11] It has a slightly bitter taste, and is not safe to drink. [11] [12] Isopropyl alcohol becomes increasingly viscous with decreasing temperature and freezes at −89°C (−128°F). Guide to Local Production: WHO-recommended Handrub Formulations" (PDF).

Fill a spray bottle with a dash of rubbing alcohol and water, spray the inside of the shoes and leave them to dry outside in the sunlight. (Do a patch test first). 3. Sanitising cloths and sponges

Although isopropyl alcohol is classified as a toxic substance, meaning that it is dangerous to consume and behaves as a mild skin irritant, it is mostly safe to use. Unlike denatured alcohol, IPA is toxic in itself. It has not had anything but water added to it, and is often used by doctors as a disinfectant and antiseptic.Isopropyl Alcohol is effective at removing oils, light greases, ink, grime, oxides, solder paste residues, adhesives residues, and flux residues. It is recommended for cleaning any of the following: a b Petersen, Thomas H.; Williams, Timothy; Nuwayhid, Naziha; Harruff, Richard (2012). "Postmortem Detection of Isopropanol in Ketoacidosis".

You can always mitigate the risk by handling it with care and staying upwind of the fumes while cooking. But ultimately you’ll have to decide for yourself whether or not it’s worth the risk. Technically rubbing alcohol and isopropyl alcohol are not the same thing, but people confuse the two products and use the terms interchangeably.
