Isopropyl alcohol is available in a large number of varieties and grades, which are generally differentiated by the amount of water in the solution and trace amounts of other chemicals or nonvolatile materials. Isopropyl alcohol is hydrophilic, so it readily accepts water into an azeotropic solution.
Whether an IPA has 0. The more water isopropyl alcohol contains, the greater the surface tension. This causes the solvent to bead up more as it dries rather than wet or sheet, which can lead to spotting. The dry time is greatly increased as the percentage of water in the alcohol solution is increased. This can be an advantage or disadvantage depending on the application. For example, isopropyl alcohol is often used as a flux remover to remove flux residues from around solder joints.
Technicians tend to prefer a fast dry time so that they can clean the electronics and bring them back into service as quickly as possible. When breaking down and removing thick, gummy, or baked-on materials, more dwell or soak time is required. Slowing down the dry time often improves the cleaning effectiveness. In the case of electrical contact cleaning, the faster evaporation time helps ensure that the flammable solvent is gone before energizing the equipment.
The following are typical grade designations of isopropyl alcohol, their respective specifications, and their operating procedures:. Rubbing alcohol does not refer to a specific grade, and may even be a different type of alcohol, like ethanol also called ethyl alcohol, CAS Consumer rubbing alcohol can also contain other ingredients like denaturant, fragrances, and colorants that are potential contaminants. Alcohol evaporates quickly and can kill pathogens on phones, laptops, tablets, and other devices.
A person should apply a small amount of the rubbing alcohol to a paper towel or cloth and gently wipe it across the electronic device. This chemical can also help remove water from an electronic device if a person accidentally drops it into water or spills some water on it. If the device was switched off at the time, removing water with the rubbing alcohol should recover it.
Jewelry can collect a lot of grime and bacteria through frequent wearing. Cleaning the jewelry with rubbing alcohol will make it more hygienic to wear. People should apply the rubbing alcohol to a soft cloth or cotton swab. They can then rub this against the jewelry to help remove surface dirt and bacteria. A review investigated the use of different aromatherapy ingredients for the treatment of nausea and vomiting following surgery.
Rubbing alcohol was one of several aromatherapy ingredients that the researchers tested. They found that inhaling rubbing alcohol vapor rapidly alleviated nausea and reduced the need for antinausea drugs following surgery. However, they noted that the studies that the review included were of low-to-medium quality. As such, further studies are necessary to confirm the findings.
A person should talk to their doctor before inhaling rubbing alcohol vapor to alleviate nausea. Inhaling too much vapor can cause serious side effects in both children and adults.
People should avoid adding rubbing alcohol to their bathwater. Prolonged exposure to rubbing alcohol can cause the skin to absorb the alcohol, which can lead to toxicity in both children and adults. As such, it is not an effective treatment for fever. In fact, inhaling large quantities of rubbing alcohol can lead to additional health problems, such as:.
Rubbing alcohol causes drying of the skin. According to the AAD, dry skin can make acne appear worse. It can also increase the frequency and severity of acne breakouts. People should, therefore, avoid using rubbing alcohol as a treatment for acne.
Anyone who is concerned about acne should speak to a doctor or dermatologist for advice on effective acne treatments. A person should not use rubbing alcohol to treat lice. Rubbing alcohol can kill lice, but it can also cause adverse reactions on the scalp. A person who has lice can ask their doctor or pharmacist for advice on effective lice treatments. According to the CDC, rubbing alcohol is not suitable for sterilizing medical and surgical equipment because it does not effectively kill bacterial spores.
A bacterial spore is a protective layer that forms around the DNA of certain bacteria. It allows the bacteria to lie dormant until environmental conditions become more favorable for their growth. According to the National Capital Poison Center , drinking a small amount of rubbing alcohol typically causes few symptoms. However, drinking a significant amount can cause poisoning and serious illness.
If an adult or child accidentally swallows rubbing alcohol, they or their caregiver should contact Poison Control immediately on If symptoms are present, a person should phone for emergency medical treatment. Pumping out and disposing of contaminated fuel can be an expensive proposition, but it can be avoided. While ethanol can contribute to contaminated fuel, other alcohols can re-disperse the water back into a burnable mixture.
The most widely available alcohol to do this job is isopropyl alcohol. If you can find a source, isobutyl alcohol is also effective.
With the increased demand for sanitizers, isopropyl alcohol may also be difficult to find. Do not use this. Isopropyl alcohol is also sold as a fuel additive. Read the labels on the additives at your automotive store. Isopropanol absorbs moisture from the air.
This means that after restoring your fuel with an addition of isopropanol, you should run the remaining fuel through the engine by taking a long trip or enough laps around the lake to use up the fuel. A few caveats are in order here. Isopropanol is said to be no more corrosive to rubber and other polymer parts of the fuel system than ethanol.
It is less aggressive than methanol.
