The soap contains phenol, but it is not all composed of phenol. The specific components are not found. The following is Baidu Encyclopedia: the pharmaceutical soap preparation method is the same as the washing soap, and the qualified soap is made from butter, coconut oil (or other oils) and a small amount of foaming agent, caustic soda and other raw materials, and the legal content of bactericides is added. Traditional soap is added with phenolic compounds, such as phenol, which is commonly known as Laisu soap. It is similar to the lysozyme used in hospitals. Phenolic compounds are toxic to all living individuals. Because phenol compounds often show red after oxidation, some of these soap are simply made red. Another kind of soap is added with oxidant in soap, which can smell acid smell is boric acid soap, Carboniferous acid soap, etc., while products with chlorination agent or other halogen compounds are added to smell the smell of bleach powder. In either way, traditional soap has a significant irritation to the skin, especially for children and women with delicate skin. Frequent use of skin can lead to allergic phenomenon. As for phenol, if it is not carefully dipped in the skin, why should alcohol be used and then washed with water is determined by the solubility of phenol. Solubility of phenol: it can be mixed in ether, chloroform, ethanol, glycerin, carbon disulfide, Vaseline, volatile oil and strong alkali aqueous solution. It is slightly soluble in water at room temperature, liquefiable when mixed with about 8% water, and can be mixed with water at 65 ℃ and almost insoluble in petroleum ether. Therefore, the easiest and safest way to remove phenol dipped in the skin is to wipe it with ethanol, let phenol dissolve in ethanol, and then rinse with a large amount of water（ You can't choose ether, chloroform, strong alkali solution, 65 ℃ or more water bar...)
