What Is Alcohol Flush Reaction?

The main ingredient of medical alcohol is ethanol, and it is a mixture. Medical alcohol is made from starch plants through saccharification, fermentation, and distillation, which is equivalent to the process of making wine, but the distillation temperature is lower than the wine, the number of distillations is higher than the wine, the alcohol content is high, the output of the finished product is high, and it contains alcohol. There are more ether and aldehyde components than wine, so you can't drink it, but it can contact the human body for medical treatment. It is a plant raw material product.

1.Purity

Medical alcohol refers to alcohol used in medicine. The purity of medical alcohol is various, and the common alcohol is 95% and 75%.

Industrial alcohol refers to industrial use

To denature a protein, it is necessary to stretch and relax the curled, spiral protein molecule. The key is to destroy the forces that form the curl and spiral. The alcohol molecule has two ends. One end is hydrophobic (one C ₂ H ₅ ), which can destroy the attraction between hydrophobic groups inside the protein. One end is hydrophilic (one OH), but it is difficult to destroy the outside of the protein. Attractive between the hydrophilic groups. on the other hand. Although the water molecule can relax the attraction between the hydrophilic groups of the protein, even if it penetrates into the bacteria, it cannot destroy the

The role of medical alcohol at different concentrations

(The following concentrations refer to volume fractions)

95% alcohol is often used to wipe UV lamps. This alcohol is commonly used in hospitals and is only used in homes to clean camera lenses.

75% alcohol is used for disinfection. This is because an excessively high concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria, and it is difficult to completely kill the bacteria. If the alcohol concentration is too low, although it can enter the bacteria, the protein in the body cannot be solidified, and the bacteria cannot be completely killed.

40% to 50% alcohol can prevent bedsores. Long-term bedridden patients' back, waist, and buttocks can cause bedsores due to long-term compression. For example, when pouring a small amount of 40% to 50% alcohol into the hands and massaging the patient's compressed area evenly, it can promote local blood circulation and prevent The purpose of bedsore formation.

25% to 50% alcohol can be used for physical antipyretics. Patients with high fever can wipe their bodies to achieve the purpose of cooling. Because rubbing the skin with alcohol can dilate the blood vessels of the patient's skin and increase the skin's ability to dissipate heat. However, the alcohol concentration must not be too high, otherwise it may irritate the skin and cause the epidermis to lose a lot of water.

The time required for different concentrations of alcohol to kill bacteria

Alcohol concentration(%)	E.coli	Staphylococcus aureus	Pseudomonas aeruginosa	Hemolytic streptococcus
100	24 hours	7 days	2 hours	15 minutes
90	15 hours	30 minutes	5 minutes	5 minutes
80	1 hour	2 minutes	2 minutes	10 seconds
70	30 seconds	5 minutes	1 minute	10 seconds
60	20 seconds	30 minutes	30 seconds	10 seconds
50	20 seconds	2 hours	30 seconds	20 seconds
40	22 minutes	4 hours	2 minutes	2 minutes
30	2 minutes	4 hours	30 minutes	30 minutes
20			24 hours	24 hours

The magical use of medical alcohol home

Medical alcohol can not only treat injuries, but also a good helper for disinfection and cleaning at home. Every family needs to prepare a bottle.

Medical alcohol fever

Wiping the skin with water first can expand blood vessels and increase heat dissipation. At the same time, the volatilization of alcohol will take away a lot of heat and play a role in reducing fever. It should be reminded that the concentration of medical alcohol is generally 75% and 95%, which will irritate the skin and absorb the epidermal moisture. Therefore, it should be mixed with the same amount or more of water before use. Chest, abdomen, scrotum and other parts; if fever, allergies, chills, pulse changes, etc., should be stopped immediately. ^[4]

Medical alcohol cleaning appliances do not rust

Alcohol is a good cleaning agent. Put it in a watering can. Spray it when the computer keyboard and TV screen are dirty. Then wipe it with a soft soft cloth firstly and then horizontally. It is clean and disinfected. It can also be kept for a month. Dust, door handles, switches, trash cans and other places are full of bacteria. Spray them frequently to kill bacteria. Alcohol has a strong decontamination effect and is volatile. The internal stains of the device can be quickly cleaned without affecting the performance of the appliance. ^[5]

Spray points in medical alcohol shoes can deodorize

Foot sweats in winter, sour and smelly in cotton shoes. At this time, you can spray alcohol inside the shoe evenly, and after drying, the smell will disappear. Other items, such as cutting boards that have a long-lasting odor, can also be sprayed with alcohol on it. After leaving it overnight, the odor will disappear. ^[4]
