What's the name of the soap for washing hands? 1
Laundry soap:
The alkali content is the largest among soaps. Its ingredients are all kinds of animal and vegetable oils and hydrogenated oils, and the manufacturing process does not need to be complicated and refined. Therefore, laundry soap is cheap, but it is not suitable for washing hands, otherwise the skin will be stimulated by alkalinity.
Soap:
Generally, soap contains antibacterial components, which can remove bacteria and viruses that cause skin infection and sweat odor, and also inhibit bacterial regeneration. Therefore, when soap is used to wash hands, it can not only remove dirt, but also moisturize the skin, disinfect and sterilize.
medicated soap:
One of the traditional medicated soaps is phenolic compound, which turns red after oxidation. Most of these medicated soaps are red, commonly known as Su soap. Another kind of medicated soap is boric acid soap, carbonic acid soap, etc., which can smell acidic odor by adding oxidant into the soap body. Therefore, medicated soap has the best cleaning and sterilization effect, and can be used for bathing, washing hands, even washing patients' clothes or as other disinfectant detergents. Su soap, boric acid soap and carbolic acid soap are obviously irritating to the skin, and the skin may be allergic if used too frequently.
Sulfur soap:
It has the efficacy of killing bacteria, fungi and mites, and has certain preventive and adjuvant therapeutic effects on some skin diseases. The concentration of sulfur soap is much lower than that of sulfur suppository used in clinic, but it is not recommended to use it continuously for a long time. It is suggested to use it intermittently, for example, twice a day at the beginning, once a day and once every three days after the symptoms are alleviated, and then gradually stop until it stops. Long-term use of sulfur soap will not lead to flora imbalance and reduce skin resistance, but it is easy to make skin dehydrated, causing skin dryness and peeling.

1. According to the main components: sodium soap, potassium soap and organic ammonium soap.

Soap has not been eliminated. Reasons
1. Surfactants are not reliable to replace soap.
Surfactants are all petroleum compounds, which are extremely cheap, and there will be 1% dioxane residue in the preparation process, but far below the pathogenic dose. Coconut amido acid made from coconut oil will only be used in some cases, and nothing else, because of the high cost.
2. The perfume used for soap is more advanced
Unlike surfactants, soap is in direct contact with air, and it is unstable and easy to be oxidized. Therefore, the perfume used for soap is all high-grade goods, which should ensure a stable fragrance in a humid and easily oxidized environment, while the perfume for facial cleanser and hand sanitizer is much simpler because the environment is stable.
3. Glycerol can be produced by making soap.
Glycerol is a very important raw material in the daily chemical industry at present. The cost of synthesizing glycerol is very high, which is far less than the cost of taking glycerol by making soap. Therefore, all major manufacturers are producing soap at full capacity. What's the name of the soap for hand washing? 2

What's the difference between soap and soap? The principle of soap sterilization?
Let's talk about the origin and historical evolution of soap. Soap is a detergent used to wash dirt, and the etymology is "blowing dirt". It means "stealing bases". Humans have a long history of using soap, but for a long time, soap is only a luxury used by the upper class.
these limits were broken by the 18th century French chemist LeBron. In 1775, the Academy of Sciences put forward an open recruitment topic about washing soda, and LeBron developed the world's first artificial soda manufacturing method in 1789. LeBron's public law is the only way to produce washing soda in the whole 19th century, which has made great contributions to the popularization of soap and the improvement of public health care.
Meeting of oil and ash
It is said that soap was first made by Babylonians around 28 BC. During the excavation of Babylonian cultural relics, a mud cylinder containing soap-like materials was found, and there was a record of mixing oil and ash to make soap on the side of the cylinder. That is to say, after humans began to barbecue with fire, the chances of oil and ash meeting increased, which led to the birth of soap.
Egyptian tomb murals, which depict the appearance of women using soap
The ancient Romans used sandpaper (Sapo) to set up a consortium on this mountain and then burned sheep to worship the gods. After the sacrifice, the person in charge of cleaning took the ashes left over from the burning home and put them in a bucket. His wife who washed the rag in this bucket found that the dirt had fallen off. Because the sheep burned in the ashes thrown in the bucket and leaked melted oil. Since then, the Romans called these putty sandpaper, which is today called the etymology of "soap".
Pliny, a famous Roman scholar, wrote about soap (sandpaper) in Natural History of China: "Soap was made by Gauls. They keep their shiny red hair with soap. Therefore, soap is useful. Soap is made from animal oil and ash. Especially goat oil and beech ash, it is best to use soap materials. There are two kinds of soaps, one is liquid soap and the other is solid soap. Germanic people prefer men to use soap rather than women. "
In addition to the mixing method of oil and ash in the Middle Ages, a new method of making soap was tried. In the 8th century, savona and other Mediterranean coastal areas began to use olive and seaweed oil to produce soap. Then, in the 12th century, a method of making white soap with natural soda (commonly known as sodium carbonate) instead of lye was developed. However, olives and natural soda are very precious, and there is a long way to popularize soap.
The most primitive form of soap is lye. In Europe, it is made of resin (animal oil) mixed with lye. In the 193s, when soap was popular, it was also called stone feeling. In addition to lye, there is also a base material made of red beans, which is an advanced cleaner, which was used from Silla to the end of Han Dynasty.
The production method is to grind red beans into a stone mill and peel them, and then grind them into a sieve to become powder as fine as rice flour. It is said that after washing your face with water once, you will get red bean powder on your hand and rub it on your face, which will remove dirt and make your skin soft. Besides red beans, they are also made of mung beans and beans.
It is not surprising that the detergent or soap made for the first time in history is extracted from plants. In the 2nd century BC, the Hittite in AsiaMinor washed them with boiled water from the leaves or roots of Saussurea involucrata. Soap grass contains a natural cleaning ingredient called saponin. They use soap grass not because they know its ingredients, but because the leaves of soap grass are crushed and rubbed in water, resulting in foam.
not only that, but also the ashes of other plants similar to soap grass have good cleaning ability, and alkalis which is well soluble in water contains a lot of components. The word "alkali" was originally Greek, meaning "burning the ashes of plants".
However, the people who played a decisive role in the appearance of soap were not Hittites, but Phoenician who traded in the Mediterranean Sea around 6 BC. But the Phoenicians made soap without knowing these chemical effects. They boil the ashes of plants, water and goat fat together, then evaporate the water and wash it with the remaining beeswax and other substances. In other words, this substance similar to beeswax is the first soap.
generally speaking, soap needs not only alkali (such as potassium carbonate), but also fat. These two things are mixed together and heated, and then they react with each other, resulting in an emulsified component with polar alkali and fatty substance, which is hydrophilic and easy to combine with water molecules, but not polar hydrophobic. Therefore, the molecules of soapy water are closely related to things other than water (such as dust), and the close dust is washed with soap bubbles. This is the basic principle of making detergents and soaps today.
what's the difference between soap and soap?
There is no big difference in essence, and the production methods are the same. The earliest history is soap, whose main function is decontamination. Now, soap can't meet all people's needs, so there is soap, which adds more ingredients and functions to soap. Then, with the progress of society, there are more and more kinds of soap, which gradually evolves into today's appearance.
Taste difference
In order to meet people's needs, some scents are added to the soaps. Good soaps add natural plant scents, while some inferior soaps add pungent essences.
In terms of functional components
Soap is mainly based on cleaning and decontamination, with strong alkalinity and strong decontamination ability, and it is the first choice for washing clothes. Soap adds ingredients beneficial to the skin, such as cleaning and moisturizing, and the style of soap is also better.
what is the sterilization principle of soap?
Soap is just like separating dirt, and the act of washing hands itself is to remove bacteria, just like the principle of soap shedding, which plays a detective role. To break and break (cell membrane) and the degree of cohesion between bacteria, soap can dissolve protein, and the cell wall of bacteria is a kind of protein called "peptidoglycan", that is to say, soap has the component of dissolving protein, which can dissolve the cell wall of this bacteria and make the bacteria die.
