What is isopropyl alcohol?

Isopropyl Alcohol is one of the most common solvents in the world. It is often known as rubbing alcohol or IPA. Isopropyl alcohol is most commonly sold in two purity grades - 70 percent and 100 percent.

Isopropyl Alcohol is also known as rubbing alcohol, usually in its 70 percent dilution.

 

What can Isopropyl Alcohol be used for?

Household uses of IPA:

  • Disinfecting surfaces
  • Making hand sanitiser
  • Cleaning windows and screens

Professional uses of IPA:

  • Sanitises beauty salon tools
  • Cleans medical equipment

 

Does isopropyl alcohol kill bacteria and germs?

Isopropyl Alcohol (particularly 60 to 90 percent) is antimicrobial against viruses, fungi and bacteria. It kills microorganisms such as bacteria, germs and fungi or halts their growth, specifically the spread of germs. Isopropyl Alcohol kilss 99.99% of germs in under 30 seconds making it an in-demand and popular sterilisation solution.

 

What’s the difference between 100% and 70% isopropyl alcohol?

The percentage of IPA correlates to the ration of purified water it is diluted with. Pure 100% IPA is not diluted with any water; common formulas include a ratio of 10 - 40% purified water.

 

Does 70% rubbing alcohol kill germs?

Yes. Purified water plays an important role in the effectiveness of Isopropyl Alcohol (IPA) as it delays the evaporation rate and therefore increasing the time it remains effective on a surface. 70 percent IPA solutions are most effective in fully penetrating the cell wall, killing the organism. This slightly diluted formula helps to destroy the harmful properties of common pathogens and microorganisms.

 

What is 70% isopropyl alcohol used for?

70% IPA is the most commonly used form of this solvent. It is used to sanitise areas where germs may be present including household surfaces, beauty salons and hospitals.

 

Can 70% Isopropyl Alcohol be used as a Disinfectant?

Yes, it is the 70% diluted solution that can act as a disinfectant because the water helps keep the solution on the surface for longer allowing it to penetrate the cell wall of the organism.

 

What is 99%-100% isopropyl alcohol used for?

The highly concentrated version of IPA is much less commonly used than 70% IPA. Most ofen, 99% IPA is used in industrial settings, on products that are sensitive to water.

 

How do you dilute isopropyl alcohol to 70 percent?

Although pure isopropyl alcohol can be diluted, we suggest purchasing a premixed 70% IPA solution. Not only is 70% IPA less expensive, it is also professionally pre-diluted, therefore removing any potential margin of error for mixing.

Rubbing Alcohol as an Insecticide

Rubbing alcohol can be used on some plants as an insecticide. It is important to check exceptions including some tropical plants before using. For a liquid detergent spray mix 1 tsp of liquid dishwashing detergent with 1 cup of rubbing alcohol in 1 quart of water. For soft-bodied insects, straight 70 percent or 90 percent Isopropyl Rubbing Alcohol can be used.

Application

For smaller insect infestations, dab insects with a cotton swab soaked in the rubbing alcohol solution. For larger infestations, the mixture can be applied by a spray bottle. Cover the entire plant as many insects like to hide under leaves!

Plant Safety

In general, your plants should not be damaged as the alcohol will evaporate quickly. This quick evaporation mitigates damage on the leaves, shoots and stems.

Spot-Test

It is of course always good to test before covering your entire plant. Rubbing alcohol should not harm the plant, however to safe-guard against unexpected results, do a spot-test on one leaf or bud first.

When You Should Repeat

While a stronger concentration of Isopropyl Alcohol is more likely to kill your insect infestation, caution is advised and different concentrations of IPA should be tested. Depending on how bad the infestation is, repeat the application process every three to seven days over a couple of weeks while monitoring for signs of damage and to make sure your infestation is easing.
