The main ingredients of soap

Soap is a daily necessity that people need in daily life, but there are actually many types of soaps. You can choose different types of soaps according to your personal needs. Especially for babies, if you want to use soap to take a bath, you must be extra careful. You must find out the main ingredients in the soap. In this way, you can avoid some dangers for your baby after using soap.

The various soaps mainly include baby soaps with advanced skin care factors; sulfur soaps with sulfur added to kill bacteria and treat superficial mold and parasites, and boric acid bath soaps with boric acid added for disinfection and sterilization; mosquito repellent soaps use mosquito repellent ingredients from traditional Chinese medicine, which are extracted at high concentrations and integrated into the soap base to achieve a mosquito repellent effect.

Different choices of raw materials will result in different qualities of soap produced. Vegetable soap matches the pH value of human skin, while other soaps made from industrial chemical strong acids and alkalis are irritating to the skin and can cause allergic reactions.

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.

Regular soap

Spices, pigments and white soap are ground and pressed into various shapes. It is the most economical one and has a good effect on general cleaning and grease removal. (

Finely ground soap

Also known as "French soap", it has a low alkalinity content and is made into a solid soap after multiple grindings. This type of soap is of course more expensive. Because it is more stable and finer, it is more commonly used for washing the face.

Floating soap

It is a soap with slightly higher humidity and is not ground. It is easy to contain air when used and is easier to float on the water surface. The cleaning effect is not bad, but it is more difficult to maintain humidity. It is easy to change shape and color after storage. It is best to use it when it is fresh.
