How to store soap and how to use soap

Soap is a skin care product that we are all familiar with, and at the same time soap is usually used for bathing. We all know that soap melts easily when it comes into contact with water, so let us understand how to store soap? How to use soap?

How to store soap

Keep the soap dry after use and do not soak it in water. Unused soap must be sealed and stored. Place it in a hydrophobic container after each use and keep it in a dry, ventilated and cool place away from direct sunlight. When purchasing a soap box, choose one with a water-filtering bottom. In this way, the excess moisture on the surface of the soap can be filtered out through the soap box, thereby extending the service life of the soap and preventing the soap from softening due to moisture. Soap that is not in use temporarily should be drained, sealed with plastic wrap, and refrigerated in the refrigerator. The shelf life depends on the storage environment and is usually one to two years. In order to avoid storing a large number of bacteria in the soap box, the soap box should be scrubbed at least once a month. When scrubbing, it can be disinfected with high-quality 84 solution.

How to use soap

Put soap on a towel, rub it evenly and rub it on your body. After rubbing evenly, rinse with warm water, then wash the towel with water, soak it in water, and rub it all over the body. If you don't wash every day: After wetting your body, repeat the above process, then use a bath towel to rub off the dust from the shed stratum corneum on your body, and then rinse with clean water. Soap is a general term for metal salts of fatty acids. The general formula is RCOOM, where RCOO is a fatty acid radical and M is a metal ion. The carbon number of fatty acids in daily soaps is generally 10-18. The metals are mainly alkaline metals such as sodium or potassium. Special-purpose soaps are also made from ammonia and certain organic bases such as ethanolamine and triethanolamine. In a broad sense, any fatty acid salt obtained by saponification or neutralization reaction of oils, waxes, rosin or fatty acids with alkalis can be called soap. Soap is soluble in water and has the function of washing and removing dirt. There are various types of soap, including toilet soap, also known as toilet soap, metal soap and compound soap.

Does soap have a sterilizing effect?

Ordinary soap has no disinfecting or bactericidal effect, and even if it does, it is "insignificant". The alkaline properties of soap can inhibit the growth of bacteria and indirectly play a role in disinfection and sterilization. The main function is to remove dirt, and some bacteria can also leave the human body along with the dirt washed away. It is best to use medicated soap for sterilization, and add the legal amount of bactericide to the soap. In addition to its cleaning and decontamination functions, medicated soap also has a bactericidal effect. Widely used in life and medicine. The medicinal ingredients added to traditional medicated soaps are phenolic compounds, such as phenol. This type of medicated soap is commonly known as Lysol soap. It is similar in composition to Lysol water commonly used in hospitals. Phenolic compounds are toxic to all living individuals. Since phenolic compounds often appear slightly red after oxidation, some of these medicated soaps are simply made red. Another type of medicated soap adds oxidants to the soap body. The ones that smell acidic are boric acid soap, carbolic acid soap, etc., while the ones that smell bleaching powder are products that have added chlorinating agents or other halogen compounds.

Is soap toxic?

Soap itself is non-toxic, but various other ingredients added to soap may be slightly toxic. The addition rate of various additives in soap is extremely low. The reason why soap can remove dirt is because it has a special molecular structure. One end of the molecule is hydrophilic and the other end is lipophilic. At the interface between water and oil, soap emulsifies the oil and allows the oil to dissolve in soapy water; at the interface between water and air, soap surrounds the air molecules to form soap bubbles. The dirt that was originally insoluble in water can no longer adhere to the surface of clothes due to the action of soap, but dissolves in the soap foam and is finally completely washed away.
