The use of soap
1, the soap is chopped and put into a bag with good air permeability, which becomes a sachet. Put it in the wardrobe or shoe cabinet, it has the functions of removing odor, preventing insects and enhancing fragrance. If the fragrance fades after a period of use, it can be taken out as a cleaner.
2. Coating a thin layer of soap on the inner side of new shoes or shoes with worn feet can effectively reduce the friction between skin and shoes.
3. Apply a layer of soap on the surface of a clean mirror, and then wipe it with a paper towel or a dry cloth, which can reduce the formation of small spots on the surface of the mirror by water vapor and have an anti-fog effect, and the dry cloth mirror will never fog again.
4. The ratio of broken soap and baking soda powder is 4: 1, which is used to clean the corner of the bathroom, such as the faucet, and the decontamination effect is stronger.
5, the smell of soap has the effect of driving away cockroaches. As long as you rub the soap in water, spray the cockroach with soapy water and block the pores of the cockroach, the cockroach will suffocate, which is much safer and simpler than using various pesticides or hitting the cockroach with the sole!
The principle of soap
The molecular structure of soap can be divided into two parts. One end is the charged polar chief operating officer-(hydrophilic site), and the other end is the nonpolar carbon chain (lipophilic site). Soap can break the surface tension of water. When soap molecules enter water, the hydrophilic part with polarity will destroy the attraction between water molecules, reduce the surface tension of water, and make water molecules almost evenly distributed on the surface of clothes or skin to be cleaned. The lipophilic part of soap goes deep into oil stains, while the hydrophilic part is soluble in water. After stirring, this combination forms smaller oil droplets, the surface of which is covered with the hydrophilic part of soap, and will not recombine to form large oil stains. If this process (also called emulsification) is repeated many times, all the oil stains will become very tiny oil droplets dissolved in water and easily washed away.

The significance of washing hands with soap
Pneumonia and diarrhea are the main causes of death among children under five. Every year, more than 3.5 million children around the world cannot meet them because of diarrhea and pneumonia.
Washing hands with soap can save the lives of millions of five-year-old children. Hand washing can also prevent skin infections, eye infections, intestinal parasitic diseases, SARS and avian influenza, which is beneficial to the health of cancer patients and HIV carriers.
Washing hands with soap is a life-saving intervention that all countries and communities can do technically and economically. This measure is popularized not only because it is good for health, but also because washing hands with soap makes people feel comfortable, reflects a person's social status and education level, and makes people closer.
Wash your hands with soap or hand sanitizer after defecation, after wiping your child's ass and before touching food with your hands.
The benefits of washing hands with soap
Hand washing is the cornerstone of public health, and new health behaviors and public health services are the main factors for the rapid decline of infectious disease mortality in rich countries at the end of 19. Washing hands with soap or hand sanitizer is one of the most effective ways to prevent diarrhea (the infection rate is reduced by half), and it is also the cheapest way, just like the isolation and safe treatment of feces and the provision of sufficient purified water. In addition, washing hands with soap can limit the spread of respiratory diseases (reducing the infection rate by a quarter). Moreover, washing hands with soap or hand sanitizer is also a powerful barrier against other diseases (such as eye infections such as worms and trachoma, skin infections such as pustules).
Soap hand washing fee
Washing hands with soap is the cheapest health intervention. Disability-adjusted years of life (Dalys) is to measure the burden of disease and the effect of health intervention by integrating years of life lost and years of disability. Obviously, washing hands with soap is the most effective way to return DALYs related to diarrhea. The cost of hand washing is much lower than that of immunization. For example, DALY's measles immunization costs between $250 and $4,500. This is not to say that vaccination is unnecessary, but to point out that due to the general lack of investment in promoting hand washing, we have missed an amazing number of opportunities to save lives in the cheapest way. Most families in the world can already afford soap, so the cost is not the reason that affects people to wash their hands with soap.
Present situation of washing hands with soap in China
During the period of SARS in 2003, the study showed that washing hands with soap 10 times a day could reduce the virus transmission rate by 55%. Statistics from the Ministry of Health show that by the end of 2008, the penetration rate of rural sanitary toilets in China was about 60%. According to the survey of nearly 65,438+08,000 schools in 65,438+06 provinces of China in 2007, only 24% schools have sanitary toilets and less than 36% schools have hand washing facilities. In addition, in 2007, a formative study in a province in western China showed that only 9% people washed their hands with soap out of nearly 3,500 times.
