Functions and Efficacy of Alcohol Ethanol is a colorless, transparent, volatile, easily ignited and non-conductive liquid.
Ethanol has many functions, a large number of which are used as alcohol. As alcohol, let's share the function and efficacy of alcohol.
Function and efficacy of alcohol 1
1, solvent; Organic synthesis; Crystallization of various compounds; Detergent; Extractant;
2. Edible alcohol can be blended with liquor; Used as an adhesive; Nitro spray painting; Solvent for varnish, cosmetics, ink, paint remover, etc. And raw materials for making pesticides, medicines, rubber, plastics, artificial fibers, detergents, etc. , can also be used as antifreeze, fuel, disinfectant, etc.
3. 75% ethanol solution is commonly used for medical disinfection.
4. Alcohol with a volume fraction greater than 99.5% is called anhydrous alcohol.
Biological use: The pigment in chloroplast can be dissolved in organic solvent anhydrous ethanol (or acetone), so the pigment in chloroplast can be extracted with anhydrous ethanol.
5.70% ~ 75% alcohol is used for disinfection.
This is because excessive concentration of alcohol will form a protective film on the surface of bacteria, preventing it from entering the interior of bacteria, and it is difficult to completely eliminate bacteria.
If the alcohol concentration is too low, it can enter bacteria, but it can't coagulate protein in the body, and it can't completely kill bacteria.
Among them, 75% alcohol has the best disinfection effect.
6, 25% ~ 50% alcohol can be used for physical antipyretic.
Patients with high fever can use it to wipe their bodies and achieve the purpose of cooling down.
Because wiping the skin with alcohol can dilate the blood vessels of the patient's skin, increase the heat dissipation ability of the skin, absorb heat by evaporation of alcohol, reduce the body surface temperature of the patient and relieve symptoms.
7. The degree of liquor indicates the volume percentage of ethanol contained in liquor (commonly used in the west to indicate the alcohol content), which is usually expressed by the volume ratio at 20℃. For example, 50-degree liquor means that 100 ml liquor contains 50 ml (20℃) ethanol.
In addition, for beer, it means the concentration of wort, which is the raw material for beer production. Taking beer with 12 degree as an example, the concentration of the extract before wort fermentation is 12% (weight ratio).
The extract in wort is a mixture of various components, mainly maltose.
The concentration of ethanol in beer is generally lower than 10%.
8. Ethanol can be used to produce acetaldehyde, ether, ethyl acetate, ethylamine and other chemical raw materials, as well as raw materials for making dyes, coatings, detergents and other products.
Function and efficacy of alcohol II
Because the ethanol entering the human body cannot be digested and absorbed, when it wants to get drunk again, it needs to increase the amount of alcohol (tolerance), but at the same time, the effect of alcohol is effective.
How to preserve alcohol after death can inhibit bacteria, so there will be some in skin care products for oily skin.

Function and efficacy of alcohol 3
The first use of alcohol: sterilization and disinfection
70%-75% alcohol is used for disinfection, including skin disinfection, medical instrument disinfection and iodine removal.
The second use of alcohol: preventing bedsores.
40%-50% alcohol is used to prevent bedsores. Bedsore will occur in the back, waist, buttocks and other parts of patients who stay in bed for a long time, and once formed, it is difficult to heal. The preventive methods are to turn over frequently, scrub frequently and massage frequently.
When massaging, the nursing staff will pour 40%-50% alcohol on their hands and massage the patient's pressed parts evenly to promote local blood circulation and prevent the formation of bedsores.
The third use of alcohol: physical antipyretic
25%-50% alcohol is used for physical cooling. In addition to drug therapy, the simplest, effective and safe cooling method for patients with high fever is the physical cooling method of rubbing with 25%-50% alcohol.
When alcohol is used to scrub patients' skin, it can not only stimulate the skin blood vessels of patients with high fever to expand, but also increase the skin's heat dissipation ability; Because of its volatility, it can absorb and take away a lot of heat, reduce body temperature and relieve symptoms.
The fourth use of alcohol: alcohol can promote the metastasis of cancer cells.
The effect of alcohol on human body Chinese medicine believes that "wine is Shui Gu's gas, sweet and hot, enters the heart and liver, and has the effects of promoting blood circulation, removing blood stasis, dredging meridians, expelling wind and cold, and invigorating the stomach.

What is the role of alcohol in medicine or efficacy? Medicinal alcohol (ethanol) is an essential medicine in medical units and family medicine boxes, and it is one of the most commonly used external preparations.
Different uses of alcohol have different functions.
95% alcohol is used as fuel.
Medical units often need to use alcohol lamps and stoves, which are used to prepare laboratory reagents or pharmaceutical preparations, heat them after ignition, and can also be used for temporary flame disinfection of small medical devices.
70%-75% alcohol is used for sterilization.
Used for skin disinfection, medical instrument disinfection, iodine deiodination, etc.
Some people think that the higher the alcohol concentration, the better the disinfection effect, which is wrong.
The function of alcohol disinfection is to coagulate protein in bacteria, thus bacteria.
However, 95% alcohol can quickly solidify the protein coated on the surface of bacteria to form a protective film, which prevents alcohol from entering the bacteria, so the bacteria cannot be completely eliminated.
If the alcohol concentration is lower than 70%, it can enter bacteria, but it can't coagulate protein in the body, and it can't completely kill bacteria.
Only 70%-75% alcohol can enter bacteria smoothly, and protein in bacteria can be effectively solidified, so bacteria can be completely eliminated.
Disinfect medical devices with 70%-75% alcohol for a soaking time of not less than 30 minutes; After soaking and disinfection, it should be washed with sterile physiological saline to avoid the residual alcohol on the instrument from irritating the body tissue.
Because alcohol can only be used for bacteria, not spores and viruses, iodine with better effect is often used for skin disinfection before medical injection or operation.
In order to reduce the long-term irritation of iodine to the skin, iodine is generally disinfected with 75% alcohol to remove iodine.
Because alcohol is irritating, 75% alcohol can be used for skin disinfection, not for mucous membranes and large wounds.
40%-50% alcohol is used to prevent bedsores.
Long-term pressure on the back, waist and buttocks of long-term bedridden patients can cause bedsores, which are difficult to heal once they are formed; The preventive methods are to turn over frequently, scrub frequently and massage frequently.
When massaging, the nursing staff will pour 40%-50% alcohol on their hands and massage the patient's pressed parts evenly to promote local blood circulation and prevent the formation of bedsores.
25%-50% alcohol is used for physical antipyretic.
In addition to drug therapy, the simplest, effective and safe cooling method for patients with high fever is the physical cooling method of 25%-50% alcohol bath.
When alcohol is used to scrub patients' skin, it can not only stimulate the skin blood vessels of patients with high fever to expand, but also increase the skin's heat dissipation ability; Because of its volatility, it can absorb and take away a lot of heat, reduce body temperature and relieve symptoms.
The specific method is: soak the gauze or soft towel with alcohol, twist it until it is half dry, and then gently wipe the patient's neck, chest, armpits, limbs, hands and feet.
The alcohol concentration used for rubbing bath should not be too high, otherwise the large-scale use of high-concentration alcohol will stimulate the skin and absorb a lot of water from the epidermis.
What effect does ethanol have on the skin? Wiping the skin with 25% to 50% alcohol (ethanol) can dilate the blood vessels of the skin, increase the heat dissipation capacity of the skin, absorb heat by evaporation, and reduce the body surface temperature of patients.
The concentration of alcohol (ethanol) should not be too high, otherwise it may irritate the skin and absorb a lot of water from the epidermis.
Long-term exposure to ethanol can lead to dryness, desquamation, chapped skin and dermatitis.
Facial flushing after drinking is caused by the temporary dilation of blood vessels under the skin, because there is an efficient alcohol dehydrogenase in this kind of human body, which can quickly convert the alcohol in the blood into acetaldehyde, and acetaldehyde has the function of dilating capillaries, which will cause redness and even flushing of the skin.
