Is soap acidic or alkaline? What are the main ingredients of soap?

Soap is a cleaning product that everyone has at home. Soap has antibacterial and deep cleansing effects. People generally use soap when cleaning. Soap is an alkaline cleaning product.

The main component of soap is sodium fatty acid, which is a salt of strong acid and weak base. It is hydrolyzed into alkaline in water and is an alkaline chemical product with a pH between 9 and 11. If you are bitten by a small insect, you will feel better after washing with soap, because the insect bite will release formic acid, and soap is alkaline, which neutralizes the acid.

There are many types of soaps, such as transparent soap, floating soap, oily soap and other types of soaps are all derived from ordinary soaps, and the ingredients are similar. The main ingredients of ordinary soaps are sodium salts of carboxylic acids R-CO2Na, synthetic pigments, synthetic fragrances, preservatives, antioxidants, foaming agents, hardeners, thickeners, synthetic surfactants, sodium carbonate, potassium carbonate, sodium fatty acids and other additives. Most of the soaps produced are white. The reason why the colored soaps we use have colors is because fragrance raw materials are added to the soaps. After grinding and mixing with the original soap, they become the soaps with other colors that we usually use.

People with dry skin should wash their face less often and avoid using alkaline soaps. People with oily skin should wash their face more often to prevent oil from clogging the pores. They can use soaps containing sulfur or salicylic acid, but should also avoid using soaps with strong alkalinity because they can irritate the skin. After washing your face, apply a hot towel for 10 minutes to effectively remove oil and keep your skin fresh. People with mixed skin should wash their face twice a day, using facial cleanser, soap, or cleansing cream.

Generally speaking, there is no difference. They are all soap-based alkaline decontamination products and can be used to wash hands, but please note:

1. Soaps contain ingredients that are beneficial to the skin, such as antibacterial, deep cleansing, protection, moisturizing, etc. Some soaps can also play a role in lubrication after cleaning, which is not available in ordinary soaps.

2. Soap is specially designed for the skin, and generally takes the skin's acceptance into consideration, so it does not cause much damage to the skin. Soap is used for washing clothes, and it focuses on the cleansing ability of clothes. I need not explain the difference between clothes and skin.

3. The ability of scented soap to remove dirt from the skin is definitely stronger than that of soap, because all formulas take the properties of the skin into consideration. While soap can clean clothes, it does not have the penetration and absorption of the active ingredients of scented soap.

4. Finally, washing your hands with soap won’t smell as good as washing them with perfumed soap.
