Dishwashing liquid daily cleaning supplies. Clean and mild, soft foam, fast decontamination, sterilization, effective and thorough cleaning, no residue, exudes elegant fruity fragrance, white and bright as new after washing, often used to ensure home hygiene and avoid germ infection. From a scientific point of view, this does make sense. After all, when we used to mix chemical labs, when we encountered difficult-to-wash grease, we directly applied strong alkaline lotion to clean it. The principle of this cleaning is that the oil will undergo a chemical change called saponification in a strong alkaline environment, from oil that cannot be dissolved in water to a carboxylate that can be lipophilic at one end and hydrophilic at the other, so Can dissolve in water. The origin of the name 'saponification' is the key reaction we use to make soap. The most traditional soap is made of 'oil + alkali'. Therefore, to change the description of the image, washing dishes with alkali is not so much 'without detergent' as it is 'self-made detergent'. Since it is a common operation to wash oil with alkali in chemical laboratories, why don't we just buy alkali powder directly in the store every day? Why did the ancients make soap pancreas, and now people buy detergent and these Woolen cloth? This is because the use of alkali to wash the grease on tableware has several defects: washing dishes with detergent, the principle is that the surfactant (similar to soap) molecules in it can dissolve in water at one end and dissolve in oil at the other end, which is equivalent to breaking the The diaphragm between oil and water is a physical change. The use of alkali to wash dishes is based on a chemical reaction between strong alkali and grease. Chemical reactions are more time-consuming and demanding than physical changes. That said, it won't be so easy to wash off quickly. Moreover, the chemical reaction has an effect on the concentration and temperature, so the effect of washing in colder times or in cold water is not good. In order to better realize the saponification reaction, it is necessary to use strong alkali. Generally speaking, strong alkalis such as sodium hydroxide (caustic soda) are the better ones. However, these strong alkalis are more corrosive and can be harmful to the human body after contacting the skin. There is a greater risk, and few people use it at home except for being deceived. (For example, some products packaged as 'shell powder' are mainly composed of a mixture of calcium hydroxide and calcium oxide). However, using some weak bases, such as sodium carbonate, is more difficult to achieve saponification, and to improve the ability to remove oil and decontamination, it needs the assistance of hot water. But even these products, which are not very alkaline, can cause damage to the skin with daily use. If it is not rinsed well, eaten, or accidentally picked up by a curious child, the risk of injury is also greater than that of dish soap. Therefore, with the progress of science, human beings did not use alkali to wash dishes on a large scale, but invented various detergent products that are softer, safer and more effective.
