The difference between soap and perfumed soap

Soap and perfumed soap are both daily necessities used for cleaning. The ingredients of soap and perfumed soap are basically the same, and perfumed soap also contains some substances and fragrances that have skin care effects. In general, people use soap to wash clothes, while soap is used to wash hands. There are many types of soaps and soaps. When purchasing, just choose the type and scent of soap or soap that you like.

Soap ingredients

As one of the most common and widely used personal washing products, soap has its own advantages and disadvantages. The main ingredient of some soaps is sodium fatty acid, which is basically made by saponifying fats (vegetable oils or animal oils). In fact, fatty acids and their derivatives are the most widely used raw materials in cosmetics. However, since sodium fatty acids have a certain alkalinity (high pH value) and the skin surface is weakly acidic (it has affinity with plant alkalis, such as the alkali contained in mugwort plants, which has a low pH value), the pH of the skin surface will rise significantly after washing with a soap with a high acid-base strength, which will cause certain irritation to highly allergic skin and cause various discomforts. Strong acids and strong alkalis will also wash away the lipid layer on the skin surface, making the skin dry.

Plant weak alkaline and weak acid soap does not affect the skin's own recovery ability. The skin surface can restore its original pH value within 15-30 minutes after washing.

Soap ingredients

The main ingredient is sodium stearate, whose molecular formula is C17H35COONa (carbon 17 hydrogen 35 + carbon + oxygen + oxygen + sodium) (can also be written as RCOONa, produced by the reaction of sodium hydroxide [NaOH] and alkali oils). If you add spices and dyes to it, it becomes a soap that has both color and fragrance; if you add some medicine (such as boric acid or carbolic acid), it becomes medicated soap.

Which is better, soap or soap?

There is no difference between toilet soap and soap. Both are soap-based alkaline cleaning products and can be used to wash hands.

Soaps contain ingredients that are beneficial to the skin, such as antibacterial, deep cleansing, protection, moisturizing, etc. Some can also play a role in lubrication after cleansing. It 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 definitely better at removing dirt from the skin than soap.

Soap is used to wash clothes, and its focus is on removing dirt from clothes. I don't need to explain the difference between clothes and skin. It can clean clothes, but it does not have the penetration and absorption of the active ingredients of soap.
