It’s best to avoid using any isopropyl mixture below 90% on circuit boards and other electrical bits. If you’re simply cleaning the adhesive off something metal or plastic, 70% might do in a pinch, but you’ll want to be sure not to spill it onto circuits or wires. There’s enough water in that lower-grade stuff that it will take longer to evaporate, and may leave behind trace impurities from the water when you’re finished.
Cleaning dry erase boards. You’ll need at least a 90 percent rubbing alcohol solution to truly remove dry erase marks. You can put the solution into a spray bottle or apply some on a washcloth or paper towel to clean the board.
It Can Remove Ink Stains
Leave the sponge or cloth to soak in a rubbing alcohol solution for a few hours, then rinse the item down before using it again. 4. Cleaning electronic devices Clark, D. E. (2001). Peroxides and peroxide-forming compounds. Chemical Health and Safety, 8(5), 12-22. Some people may find rubbing alcohol irritates their skin. People can wash the substance away with soap and water if this occurs. Isopropyl alcohol is often used in DNA extraction. A lab worker adds it to a DNA solution to precipitate the DNA, which then forms a pellet after centrifugation. This is possible because DNA is insoluble in isopropyl alcohol.

ISBN 978-0471419617. Isopropyl alcohol does not cause an anion gap acidosis, but it produces an osmolal gap between the calculated and measured osmolalities of serum, as do the other alcohols. [33] The findings of acetone without acidosis leads to the sine qua non of "ketosis without acidosis." a b c d e Slaughter RJ, Mason RW, Beasley DM, Vale JA, Schep LJ (2014). "Isopropanol poisoning".

Isopropyl alcohol ( IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable organic compound with a pungent alcoholic odor. [9] As an isopropyl group linked to a hydroxyl group ( chemical formula (CH 3) 2CHOH) 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 propan-1-ol and ethyl methyl ether. They all have the formula C 3H 8O.Astringent. Alcohol is a natural astringent that can help to tighten pores and leave your skin feeling refreshed. Apply after cleansing your skin and before applying moisturizer or sunscreen. Unfortunately, rubbing alcohol can be very drying to skin so don’t use on any dry areas. Also, applying it after shaving or to open acne areas can cause a burning sensation. To use isopropyl alcohol for sore muscles, apply a generous amount to the skin and rub in until the alcohol dries.

Technically rubbing alcohol and isopropyl alcohol are not the same thing, but people confuse the two products and use the terms interchangeably.There are two routes for the hydration process and both processes require that the isopropyl alcohol be separated from water and other by-products by distillation. Isopropyl alcohol and water form an azeotrope, and simple distillation gives a material that is 87.9% by mass isopropyl alcohol and 12.1% by mass water. [19] Pure ( anhydrous) isopropyl alcohol is made by azeotropic distillation of the wet isopropyl alcohol using either diisopropyl ether or cyclohexane as azeotroping agents.

Alcohol baths are dangerous for the same reason as applying alcohol to the skin for fevers. The body may absorb the alcohol and cause toxic symptoms.
