Is there any fake 75% alcohol? How to distinguish the authenticity of 75% alcohol?

The new coronavirus is afraid of alcohol and high temperatures, so many people often use alcohol for disinfection. It is best to use 75-degree alcohol for alcohol disinfection, so that the new coronavirus can be killed. So how to distinguish whether 75-degree alcohol is real or fake? Let's take a closer look!

How to distinguish the authenticity of 75% alcohol

75% alcohol will have a strong smell of alcohol, if it is very light or no smell, it is fake. There is no specific measure to judge the authenticity, and other things such as burning are a little dangerous. It is recommended that you judge by smell.

There are many alcohols that are not 75% medical alcohol. Fake alcohol is not ethanol but 95% methanol. Methanol not only has no disinfecting effect, but also has a certain degree of toxicity. The way to distinguish the real from the fake is to smell it. Fake alcohol has no smell of alcohol at all, but it can be ignited.

What were the reviews of the store when you bought it online? If the reviews are okay, then it's not a big problem. If someone in your home drinks, you should be able to smell the alcohol content. Secondly, you can put it in the refrigerator to freeze it. If the alcohol content is really high, there will generally be little or no ice.

What to do if you buy fake 75% alcohol

If you accidentally buy fake alcohol, and use it after diluting it with water according to the instructions for using alcohol, you will add a certain amount of water to dilute it and pour it into a spray bottle for use. It will be ingested into the body through the respiratory tract and skin and become toxic. Short-term large-scale inhalation may cause mild eye and upper respiratory tract irritation symptoms. After a period of incubation, headaches, dizziness, fatigue, vertigo, drunkenness, confusion, delirium, and even coma may occur. Optic nerve and retinal lesions may cause blurred vision, double vision, and even blindness in severe cases.

Therefore, when you buy alcohol, you must pay attention to whether there is a health license. Keep your eyes open and be more discerning when buying. If you accidentally use fake alcohol and feel any discomfort in your body, you must seek medical attention in time!

Does 75% alcohol need to be diluted?

Alcohol concentration that is too high or too low cannot completely kill the virus. 75-degree alcohol has the best disinfection effect, so 75-degree medical alcohol does not need to be diluted and can be used directly.

Previously, Academician Li Lanjuan, a member of the National Health Commission's high-level expert group and a famous infectious disease expert in my country, also stated in an interview with reporters that 75% alcohol can kill viruses.

When the concentration of medical alcohol is higher than 70%, the volatile alcohol will increase the risk of explosion, so medical alcohol is not suitable for large-scale spraying. You can use cotton balls or cotton swabs soaked in alcohol to wipe mobile phones, door handles and other places with more pathogens. After getting off work or going home, you can also spray 75-degree medical alcohol directly on your hands for disinfection.

Precautions for using 75% alcohol

Be careful when using alcohol

Alcohol has a low flash point and is prone to spontaneous combustion when exposed to fire or heat. When used for disinfection at home, you can use a clean non-woven cloth, towel or cotton ball, dipped in a small amount of 75% alcohol to wipe door handles, mobile phones and related items. Never use a spray bottle to spray, as it will flash and explode when exposed to fire!

When using alcohol, keep the area ventilated and away from high-temperature objects. Do not allow alcohol to come into contact with open flames. For example, turn off indoor gas stoves and other fire sources first.

In addition, after using alcohol disinfection, you should not immediately make phone calls, smoke, use electric mosquito swatters, etc. When disinfecting the surface of electrical appliances, be sure to turn off the power first.

Precautions when using directly on the skin for disinfection

If you are at home and have not gone out, and there are no suspected infected people or people in close contact with epidemic-prone areas at home, alcohol disinfection is not necessary. You can wash your hands frequently with soap and other cleansers, or use alcohol-based hand disinfectants, which can replace 75% alcohol, but can protect the skin better than the latter.

If you only have alcohol at home, the 75% concentration is very irritating and is suitable for disinfecting intact skin, but not for disinfecting mucous membranes. After using alcohol for disinfection, the sebum membrane barrier of the skin will be damaged to a certain extent and become fragile. Proper care and moisturizing should be carried out in time, and the appropriate moisturizer should be selected according to the skin type to avoid skin damage.

Alcohol cannot be mixed with 84 disinfectant

If two disinfectants are mixed together, will the disinfection ability be doubled? If alcohol and 84 disinfectant are mixed together, a reaction may occur. Although alcohol and 84 disinfectant do not produce chlorine gas, it is not recommended to mix them together, which will reduce the disinfection effect and even produce some organic chlorides. Therefore, alcohol cannot be mixed with 84 disinfectant.
