How to prepare 70% isopropyl alcohol disinfectant?

With the outbreak of the epidemic, isopropyl alcohol disinfectant has become one of the indispensable disinfection products in daily life. 70% isopropyl alcohol disinfectant is widely used in hospitals, families, public places and other places for its good disinfection effect. How to prepare 70% isopropyl alcohol disinfectant? This article will introduce the preparation method, required materials and precautions of 70% isopropyl alcohol disinfectant in detail to help everyone better understand and operate.

The Principle and Function of 70% Isopropyl Alcohol Disinfection Solution

before understanding how to prepare 70% isopropyl alcohol disinfectant, let's briefly understand the disinfection principle of 70% isopropyl alcohol. As a commonly used disinfectant, isopropyl alcohol has broad-spectrum antibacterial effect. A concentration of 70% isopropanol is most suitable because it can effectively penetrate the cell membrane of bacteria and viruses and destroy their structure, thereby achieving bactericidal effect. However, the concentration of isopropyl alcohol is too high, which will form a protective film and prevent it from entering the cells. Therefore, the concentration of 70% is considered to be the most effective disinfection ratio.

Materials required for preparation of 70% isopropyl alcohol disinfectant

preparing a 70% isopropyl alcohol disinfectant requires some basic materials to ensure that you can make a disinfectant that is both safe and effective. Here are the materials required:

1. isopropyl alcohol: Choose isopropanol with higher purity, at least 90% isopropanol.
2. Distilled water distilled water is used to dilute isopropyl alcohol to ensure the precise concentration of the disinfectant.
3. Measuring cup or cylinder: Used to accurately measure the volume of liquid.
4. Agitator for mixing liquids.
5. Storage bottle: Used to store the prepared disinfectant, it is best to choose a bottle with good sealing.

Preparation steps of 70% isopropyl alcohol disinfectant

the steps of preparing 70% isopropyl alcohol disinfectant are not complicated, and can be operated according to the following steps:

1. measure the ratio of isopropanol to water: Suppose you want to prepare 100 ml of 70% isopropanol disinfectant, you need to use 70 ml of isopropanol and 30 ml of distilled water.
2. Pour in isopropyl alcohol: First, pour 70 ml of isopropyl alcohol into a clean container.
3. Add distilled water then, 30 ml of distilled water was added thereto. The total amount of disinfectant solution can be adjusted as needed.
4. Mix well: Use a stirrer to gently stir the liquid to ensure that the isopropanol and water are thoroughly mixed.
5. Bottling Storage: Finally, pour the prepared disinfectant into a sealed bottle and store it in a cool and dry place, away from direct sunlight.

Matters needing attention in the preparation of 70% isopropyl alcohol disinfectant

when preparing 70% isopropyl alcohol disinfectant, the following points must be paid attention:

1. proportionally accurate when preparing, the ratio of isopropanol to water must be accurate, and 70% concentration has the best disinfection effect. Use a measuring cup or cylinder for accurate measurement to avoid excessive or low concentrations.
2. Use pure distilled water: Try to use distilled water instead of tap water to avoid impurities in the water affecting the disinfection effect.
3. Storage conditions: The prepared disinfectant should be stored in a cool and dry place to avoid high temperature and sun exposure and prevent the volatilization of the disinfectant.
4. Avoid contact with fire sources: Isopropyl alcohol is a flammable liquid, which should be kept away from open flames and high temperature objects to ensure safety.
5. Regularly replace the disinfectant: The disinfectant stored for a long time may lose its effect. It is recommended to reformulate it at regular intervals.

Conclusion

through the above steps, you can easily prepare a 70% isopropyl alcohol disinfectant. This disinfectant has a strong bactericidal function and can effectively eliminate bacteria, viruses and pathogenic microorganisms. The correct preparation method and storage conditions are the key to ensure its disinfection effect. I hope this article can help you understand how to prepare 70% isopropyl alcohol disinfectant and provide convenience for your daily disinfection.
