100% IsopropylAlcohol comes in handy for industrial cleaners and professionals. It is great for disinfecting hard surfaces and cleaning surfaces like glass. On an industrial level, 100% Isopropyl is also a great product for cleaning gadgets like mobile and tablets.

99% IsopropylAlcohol has just 1% of moisture content; it is still vital for chemical formulations that specifically require 99% Isopropyl.

Even though both 99% and 100% Isopropyl have similar features, certain tasks require 99% specifically instead of 100%.

Apart from the common industrial cleaning and disinfecting usage, 99% Isopropyl has dedicated usage as well. It comes in handy for Laboratory use and special chemical formulations.

What is 91% IsopropylAlcohol Used for?

What is 50% IsopropylAlcohol used for?

Is 50% IsopropylAlcohol any good? 50% IsopropylAlcohol means 50% Alcohol and 50% purified water.

Commonly the 50% concentration works as an antimicrobial and disinfectant.

Because it is watery to a really high level, it efficiently penetrates the bacterial cell wall and destroys potential infection-causing enzymes. In simple words, its level of dilatation increases its potency of antimicrobial properties.

Why is 70% Isopropyl Alcohol better than 91% or 99% Isopropyl Alcohol?

There is a common misconception that a higher concentration of RubbingAlcohol is better. However, in reality, and real-time usage, the scenarios speak else way.

When used as a disinfectant, the higher the concentration of Alcoholic acts less effectively it kills pathogens. According to research conducted by microbiologists, 91% or 99% IsopropylAlcohol is too powerful.

When used for insects, it causes an external injury that further by forming a protective wall shields them from any other harm.

Why 70% Isopropyl Alcohol is better?

In other words, it means that when the outer membrane of an insect is solidifying, the higher Alcohol concentration can put no further harm.

Also, because 91% or 99% IsopropylAlcohol evaporates very fast, that time frame does not allow the solution to penetrate inside insects’ bodies for killing them further.

However, when we talk about 70% isopropyl alcohol, it by far works as the best disinfectant amongst any RubbingAlcohol. Because it has 30% purified water content, it easily penetrates through the cell membrane of the bacteria and thus kills them.

Also, the dilatation of absolute Alcohol is necessary for denaturing process of proteins, which will further allow the solution to enter the cells. 70% IsopropylAlcohol easily enters the cell to denature both structural and enzymatic proteins.

It further increases the efficiency of its antimicrobial properties. Also, due to the extended water content, 70% of Isopropyl does not evaporate that quickly and thus has enough time to do the job.

This is why 70% isopropyl alcohol is far better at killing bacteria and infections instead of 91% or 99% isopropyl alcohol.

It isn’t about the Alcohol but the water content that ensures penetration and also provides enough time frame (before evaporation) for the solution to work.
