Both boys and girls use facial cleanser in the morning and evening every day, because the face will be polluted by various kinds of radiation and dust in the daytime. It is very important to use this cleanser to remove the dirt on the skin, make the skin fresh, and help to maintain normal physiological state. So, is there potassium hydroxide in facial cleanser harmful to skin?
The potassium hydroxide in facial cleanser will not harm the skin. Because when potassium hydroxide reacts with oil, it is not potassium hydroxide. It can promote the hydrolysis of oil and neutralize the acid after hydrolysis.
Alkali is necessary for making cleaning products. Generally, potassium hydroxide is used when making liquid soap and sodium hydroxide is used when making solid soap. They are all bases. Alkali reacts with oil to form soap and glycerin. The main component of mature soap is "high fatty acid salt", which is a kind of surfactant with oil and water friendly ends. The lipophilic end combines with the peroxide grease and dirt in the skin. When flushing, the hydrophilic end will combine with the water to remove the dirt, so it plays a role of cleaning. This is the cleaning principle of solid soap or liquid soap.
It can be seen that the presence of potassium hydroxide in facial cleanser will not harm the skin, because this compound can neutralize with oil and lose its original corrosiveness, and it is easy to absorb moisture in the air and deliquesce, so it will not harm the skin. This is also an important reason that it can be used in various daily necessities.
