How to choose alcohol wipes?

The reason why alcohol can be disinfected is because alcohol can absorb the water of bacterial protein, decompose and solidify through dehydration, so as to achieve the purpose of sterilization. Experiments have shown that if the alcohol concentration is too high, a protective film will be formed on the surface of the bacteria, and it cannot enter the bacteria. The alcohol with a concentration of about 75% can gradually continue until the protein on the surface of the bacteria is not mutated. Therefore, when choosing a product, you must choose a true 75% alcohol product., The ratio of alcohol is sufficient.

Regarding how to distinguish the authenticity of 75% alcohol, I have researched several methods myself, and I will share with you here:

The first way is to smell the wet wipes with high alcohol content. The smell is very strong and it is irritating. When I smelled it for the first time, I suddenly couldn't prevent it. I didn't know how much it smelled . As a result, I took a sharp breath and felt dizzy. For half an hour, it was almost a test with "rope life". When you smell it, you must take a small breath.

The second why is to twist it. After taking out the wet wipes, twist it firmly. If you can't twist it out, it proves that the alcohol content is too low, it is not wet enough, and the wipe is not clean ; if the moisture content is too high, it will drip; if it is 75% Alcohol will only flow along the way.

The third option is to let the 75% alcohol wipes dry on the window sill, and then touch and smell them for a few minutes. At 7 minutes, the alcohol smell is still strong, and at 9 minutes, the alcohol smell is not It's too big. At 11 minutes and 30 seconds, the wipes are only slightly damp. At 13 minutes, they feel almost like dry cotton.

The fourth method is to burn it. The 75% alcohol wipes will burn easily. The flame is very big. If the alcohol content is low, the flame will not be so big. However, the non-woven fabric is not lit. After the alcohol is burned, you can directly touch it with your hands. The non-woven fabric is as dry and soft as cotton. Then, I ignited the non-woven fabric again, and it ignited easily, proving that most of the water had evaporated.

This proves that after the alcohol evaporates, the water will quickly evaporate, and the water content is not high; if the alcohol tastes gone, but the wipes have been wet, then "too water"!

After these four steps, it is basically possible to judge whether a 75% alcohol wipe is good or bad.
