What kinds of soaps are there? 1 laundry soap:
The alkali content is the largest in soap. Its ingredients are all kinds of animal and vegetable oils and hydrogenated oils, and the production process does not need to be complicated and elaborate. Therefore, although laundry soap is cheap, it is not suitable for washing hands, otherwise alkalinity will irritate the skin.
Soap:
Generally, soaps have antibacterial components, which can remove bacteria and viruses that cause skin infections and sweat smell, and also inhibit bacterial regeneration. Therefore, washing hands with soap can not only remove dirt, but also moisturize the skin, disinfect and sterilize.
Medicinal soap:
One of the pharmaceutical ingredients added in traditional medicated soap is phenolic compounds, which will turn red after oxidation. Most of these medicated soaps are red, commonly known as Su soaps. Another kind of medicated soap is boric acid soap, carbolic acid soap, etc. You can smell the acidic smell by adding oxidant to the soap body. Therefore, medicated soap has the best cleaning and sterilization effect, and can be used for bathing, washing hands, even washing patients' clothes or as other disinfection detergents. Su soap, boric acid soap and carbolic acid soap are obviously irritating to the skin, and the skin may be allergic if used too frequently.
Sulfur soap:
It has the efficacy of killing bacteria, fungi and mites, and has certain preventive and adjuvant therapeutic effects on some skin diseases. The concentration of sulfur soap is much lower than that of sulfur suppository used in clinic, but it is not recommended to use it continuously for a long time. It is recommended to use it intermittently, for example, twice a day at the beginning, once a day and once every three days after the symptoms are relieved, and then gradually stop using it until it stops. Long-term use of sulfur soap will not lead to flora imbalance and reduce skin resistance, but it is easy to dehydrate the skin, resulting in dry skin peeling.
What kinds of soaps are there? 2 The main types of soap are as follows:
1, according to the main components: sodium soap, potassium soap and organic ammonium soap.
2. According to additives, it can be divided into peroxide soap, urea soap, sand soap, synthetic soap and compound soap.
3. According to the appearance, it can be divided into transparent soap, translucent soap, liquid soap (actually shower gel), paste soap, pattern soap, paper soap, soap chip and broken soap.

5. According to the use, it can be divided into cosmetic soap, deodorizing soap, sterilizing soap, slimming soap, medicinal soap, shaving soap, hand washing soap, face washing soap, baby soap, aged soap, skin nourishing soap, etc.
The reason why soap has not been eliminated.
1, surfactant instead of soap is not reliable.
Surfactants are all petroleum compounds, and their prices are extremely low. During the preparation process, there will be 100% dioxane residue, but it is far below the pathogenic dose. Coconut amido acid made from coconut oil will only be used in some cases, but not in other cases, because of the high cost.
2. The perfume used for soap is more advanced.
Soap is different from surfactant, it is unstable in direct contact with air and easy to be oxidized. Therefore, the spices used in soap are all high-grade goods, and it is necessary to ensure a stable fragrance in a humid and easily oxidized environment, while the spices used in facial cleanser and hand sanitizer are much simpler because the environment is stable.
3. When making soap, glycerol can be made by the way.
Glycerol is a very important raw material in the daily chemical industry at present, and the cost of synthesizing glycerol is very high, which is far less than taking glycerol when making soap. Therefore, major manufacturers are producing soap at full capacity.
What kinds of soaps are there? Soap is an essential washing and nursing product in daily life. It is a product made of surfactant such as sodium fatty acid as the main raw material and some appearance modifiers. Generally speaking, soap can be divided into seven categories:
1, general soap: perfume pigment and white soap are ground and pressed into various shapes, which is the most economical one, and the general cleaning and degreasing effect is good;
2. transparent soap: It contains more than 10% glycerin and part of vegetable oil. After use, the skin feels slippery, much like oily soap, and it is often used by people who wash their faces or have dry skin;
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 oil when grinding will form an oil layer on the skin surface when cleaning, which is suitable for dry skin, but the washing effect is slightly poor;
5. Fine grinding soap: low alkalinity solid soap is made by repeated grinding. This kind of soap is more expensive, because it is relatively stable and delicate, so it is often used as a face wash;
6. Special types of soap: such as liquid, colloid, or medical use, it is necessary to add bactericide, scrub, medicine, deodorant, etc. Some of them are called "olive soaps" with olive oil and sodium hydroxide added. The cleaning liquid and emulsion where cosmetics companies are located are not hand sanitizers, but emulsions or creams containing emulsifiers, which are mainly used to remove finished products with special cosmetic designs;
7. essential oil soap: A very popular soap in recent years, which is mainly extracted from plant essential oil.
8. Amino acid soap: weakly acidic, mild and non-irritating, it is the most popular, popular and advanced soap at present. On behalf of Naichi 'ao Xiaonai Tuanzi, he has a good reputation.
