What are the ingredients of soap-based facial cleansers? What are the ingredients of soap-based facial cleansers?

Everyone must have heard of soap-based facial cleansers. Many people say that soap-based facial cleansers can cause a lot of damage to the skin. In fact, soap-based facial cleansers are not that scary. As long as you control the frequency of use, the cleaning power is still great.

The ingredients of soap-based facial cleansers are mainly fatty acids + alkali, polyols, emulsifiers, surfactants and other additives. Among them, fatty acids + alkali are the core of the entire facial cleanser system. Its product stability, cleaning ability, foam effect, irritation, etc. all depend on the selection and ratio of fatty acids. Soap base is a common surfactant, that is, a detergent, which has an ideal cleaning ability, but at the same time it will cause certain damage to the skin.

1. Fatty acid soap: fatty acid soap oil is obtained by esterification of higher fatty acids and alkali. In addition to this, fatty acid substances can also be seen in many cleansers, which are mainly used to adjust the consistency, foam properties and irritation of cleansers.

2. Other surfactants: compounded to improve detergency, foam and irritation.

3. Softener: dissolves and emulsifies skin dirt and plays a role in nourishing the skin. After cleansing, it will form a thin skin care film on the skin surface to prevent excessive degreasing of the skin. Emulsifiers can be selected from fatty acids, higher alcohols, lanolin, beeswax, olive oil, coconut oil and jojoba oil.

4. Moisturizer: It moisturizes, softens and lubricates the skin. The most common ones are glycerin and propylene glycol, while the more advanced ones are chitosan, lactic acid and sodium lactate. The most advanced ones are pyrrolidone carboxylic acid, hydrolyzed collagen and hyaluronic acid.

5. Functional ingredients: For example, whitening ingredients can be added to whitening cleansers, and bactericidal and antibacterial agents can be added to acne-removing cleansers.

6. Metal chelating agents: prevent the formation of soap scum by combining with hard water, commonly used EDTA and various sodium salts, sodium hexametaphosphate

7. Deionized water: maintain and replenish the moisture of the stratum corneum, dissolve water-soluble dirt, and maintain the emulsion state

8. Preservatives and flavors: prevent bacterial growth and add fragrance to the product.

The main thing is soap base. Soap base is not something particularly professional or complicated. In short, it is the product of fatty acids and alkalis under heating conditions. Therefore, if "fatty acids and alkalis" appear at the same time in the ingredient column, it is a saponification formula.

The list is as follows:

Fatty acid

Myristic acid

Lauric acid

Palmitic acid

Stearic acid

Alkali

Sodium hydroxide

Potassium hydroxide

Triethanolamine

AMP(2-Amino-2-methyl propanol)

The first category is a saponified formula containing facial soap ingredients; the second category is a formula that does not contain soap at all, but is mainly composed of synthetic surfactants. The properties of saponified facial cleansers are not far from those of facial soaps, that is, they are alkaline and have good degreasing power. The feeling right after washing is very refreshing, and the pores on the whole face seem to be able to breathe freely. However, once the water on the face evaporates naturally, the skin will still be too tight and dry. Therefore, in winter, it is only suitable for people with oily skin, but not for long-term use. Kayan Amino Acid Facial Cleanser is the second category, with the main ingredients being high-quality amino acid surfactants, and the pH value is about 5.5-6.5, which is weakly acidic. And human skin is also weakly acidic, with a pH value between 5.5-6.5.

The only skin that is suitable for soap-based products is oily skin. Occasionally using soap-based facial cleansers does not have serious consequences. However, if used for a long time, it is easy to remove lipids in the skin, such as ceramides. The oily moisturizing components in the skin are lost, and moisture cannot be retained. The body will receive signals to secrete oil to ensure that the skin is not too dry, resulting in an oily face. If the loss of oily moisturizing components in the skin exceeds the synthesis rate, it will cause thinning of the keratin and skin sensitivity in the long run. For example, skin problems such as red blood streaks will appear.
