Isopropyl Alcohol or 2-Propanol is a very commonly used disinfectant within pharmaceutical companies, hospitals and cleanrooms. It is even used in the purification of electronics and medical device manufacture. It has a number of different purity grades and they are designed for different use. They are beneficial cleaning chemicals and disinfectants, and depending on how concentrated they are, they can get rid of all sorts of bacteria and impurities.
Between the concentrations of 60% and 90%, Isopropyl alcohol is a very effective agent against microbial bacteria, fungi, and viruses. Higher concentrations don’t generate a much more desirable effectiveness against bacteria, fungi and viruses. This is because, there has to be a significant enough presence of water with the Isopropyl alcohol in order to be effective. And this percentage of water needs to be at least more than 10% within the solution. And the mixture of 30% water with 70% Isopropyl alcohol works best.
The reason water is so important is because it acts as a catalyst and has a major role in denaturing the proteins of cell membranes of vegetative cells. 70% IPA solutions are very effective in breaching the cell wall fully. Also, the presence of water slows down evaporation and increases the surface contact time with the membrane. With 91% IPA, the evaporation is instant and protein coagulates, rendering the effect of the IPA greatly reduced.
Note: These chemicals are meant to be used for research, industrial work, cleaning or disinfecting.
