91% Isopropyl alcohol, which is commonly known as medical alcohol, is a high-concentration alcohol with a high degree of purity. It has strong solubility and permeability and is widely used in various fields such as disinfection, medicine, industry, and scientific research.

Firstly, let’s look at the characteristics of 91% isopropyl alcohol. This kind of alcohol has a high degree of purity and contains only a small amount of water and other impurities. It has strong solubility and permeability, which can quickly penetrate the surface of the object to be cleaned, dissolve the dirt and impurities on the surface, and then be easily rinsed away. In addition, it has good chemical stability and is not easily decomposed or contaminated by bacteria or other microorganisms.

Now let’s look at the uses of 91% isopropyl alcohol. This kind of alcohol is commonly used in the fields of disinfection and medicine. It can be used to clean and disinfect the skin and hands before surgery or in emergencies. It can also be used as a preservative in pharmaceutical industry to make various kinds of drugs. In addition, it is also widely used in industry and scientific research. For example, it can be used as a solvent in the production of paints, adhesives, etc., and also as a cleaning agent in electronic industry, precision instruments, etc.

However, 91% isopropyl alcohol is not suitable for all purposes. Its high concentration may cause irritation to the skin and mucosa of the human body if used improperly. In addition, if it is used excessively or in a sealed environment, it may cause asphyxiation due to displacement of oxygen. Therefore, when using 91% isopropyl alcohol, it is necessary to pay attention to safety measures and follow the instructions for use strictly.

In summary, 91% isopropyl alcohol has strong solubility and permeability, good chemical stability, and wide application prospects in the fields of disinfection, medicine, industry, and scientific research. However, it also needs to pay attention to safety measures when using it to ensure that it can play its best role while ensuring personal safety.
