2. Fine grinding soap: also known as French soap, it contains low alkalinity and is made into solid soap after repeated grinding. Of course, this soap is more expensive. Because it is relatively stable and delicate, it is often used as facial cleanser.
3. Floating soap: It is a kind of soap with slightly higher humidity and does not need grinding. When in use, it is easy to contain air and float on the water. The cleaning effect is good, but it is difficult to keep the humidity. It is easy to deform and change color after storage, and is suitable for fresh use.
4. Oily soap: Adding high-concentration grease when grinding will form an oil layer on the skin surface when cleaning. It is suitable for people with dry skin, but the washing effect is slightly worse. Because it is often used on babies, it is also called baby soap.
5. transparent soap: It contains more than 10% glycerin and some vegetable oil. After use, the skin feels smooth, much like oily soap. It is often used by people who wash their faces or have dry skin.
6. Special types of soap: such as liquid soap, colloidal soap or medical soap, disinfectant soap, detergent soap, medicinal soap, deodorant soap, etc. Add olive oil and sodium hydroxide as needed. Cleaning liquids and emulsions produced by cosmetic companies are not liquid soaps, but emulsions or creams containing emulsifiers, which are mainly used to remove special cosmetics.
