Soap plays the role of a health guardian in our lives and is an essential companion in our daily lives. The main ingredients of soap are fatty acid sodium and other surfactants. After processing and shaping, it becomes the soap we use today. There are many varieties of soap on the market, so how do consumers choose the right soap for themselves?
Experts suggest that the criteria for choosing soap are less fragrance, light color, and weak alkalinity. For example, white soap should be pearl white or milky white, as this kind of soap is more beneficial to human health. When choosing white soap, there are also some issues to pay attention to. Some products use a large amount of fluorescent whitening agents or titanium dioxide to whiten, although they may appear very white, this kind of whiteness is different from normal white and should not be chosen. In addition, soap that contains fluorescent whitening agents or titanium dioxide will contain a substance called "diethyl phthalate," which can damage the DNA of adult male sperm and cause infertility. Furthermore, when purchasing soap, pay attention to whether the manufacturer and address are indicated in Chinese on the packaging. If not, it may be a counterfeit and inferior product, so do not buy it.
Soap can be divided into two types based on its composition: soap containing fatty acid sodium and additives, and compound soap. People can choose and purchase according to the nature of their skin. Soap rich in lipids can keep the skin moisturized and increase the nutritional content of the skin, achieving the effect of cleansing and moisturizing. It is suitable for people with dry skin. Those with oily skin can choose compound soap because it can remove the oil from the skin, achieving the effect of cleansing and skincare. Both types of soap are suitable for people with neutral skin.
A friendly reminder from the editor:
In the minds of many people, it is always believed that the higher the concentration of disinfectant, the better. However, the fact is quite the opposite. When the concentration of disinfectant is too high, it is easy to form a protective film on the surface of bacteria, making it difficult to eliminate them. Moreover, high concentrations of disinfectant can irritate the oral and nasal mucosa, causing damage to the respiratory tract and making it easier to be infected by pathogens. Disinfectant contains chlorine, which evaporates quickly and has strong corrosiveness. When the concentration is too high, it can irritate the body and cause poisoning. Therefore, it is necessary to prepare disinfectant according to the instructions and remember to ventilate after disinfecting with closed doors and windows.
