Introduction

The main component of 75% alcohol is ethanol, which is widely used as a disinfectant. Its disinfecting effect primarily stems from ethanol's ability to kill bacteria. To ensure safety and effective disinfection, it is recommended to use 75% alcohol in a well-ventilated environment and keep it away from sources of ignition. Before use, read the product instructions carefully to understand the correct usage methods and precautions.

Under normal circumstances, 75% alcohol disinfectant can be directly sprayed, but it is important to keep it away from open flames such as gas stoves and cigarette butts. Detailed explanation is as follows:

The main component of 75% alcohol is ethanol, which is widely used as a disinfectant due to its antibacterial properties. Ethanol works by destroying the cell walls of bacteria, causing the proteins inside to denature, thereby effectively killing or inhibiting bacterial growth. A concentration of 75% is considered optimal for disinfection, as it maximizes ethanol's antibacterial effectiveness while minimizing irritation and damage to skin and objects. However, ethanol is a flammable and explosive liquid, so it is crucial to keep it away from sources of ignition, such as gas stoves and cigarette butts, to prevent fires and explosions. When 75% alcohol is sprayed into the air or comes into contact with an open flame, it can easily ignite and even cause a fire, posing serious threats to life and property.

To ensure safety and effective disinfection, it is recommended to use 75% alcohol in a well-ventilated environment and keep it away from fire sources. Read the product instructions carefully before use to understand the correct application methods and precautions. Regularly check the expiration dates of disinfecting products to ensure they are in optimal condition.
