Non-Soap Based Surfactants

Non-Soap Based Surfactants
There are many types of surfactants, and they vary greatly in their skin irritation. They can be categorized as cationic surfactants, anionic surfactants, and nonionic surfactants. Surfactants are often used in conjunction with soap bases to buffer the high pH of the soap base, reduce the irritation of the soap base, and improve skin feel. Surfactants are also often used in combination with each other to meet different needs.


The skin irritation of epimers is generally: cationic epimers > anionic epimers > amphoteric ≈ nonionic epimers.
Cationic surfactants are not used in cosmetics.
Anionic surfactants
Common anionic surfactants include: sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), sulfosuccinate, monoalkyl phosphate (MAP), and others.
The SLS/SLES system is alkaline and has excellent degreasing power, but it is also very irritating (no less than soap-based) and tends to tighten the skin. It can be used on oily skin, but dry and sensitive skin should be avoided.


Sulfosuccinate salts: e.g., disodium PEG-2 oleamide sulfosuccinate, disodium lauryl ethoxylate sulfosuccinate (DLES), disodium cocoyl ethanolamide sulfosuccinate. Mild to the skin and reduces the irritation of other surface actives.
Hydroxyethanesulfonates: e.g., Sodium Cocoyl Hydroxyethanesulfonate. Mild and non-irritating to the skin, rich and creamy foam, good synergy with other skin care products.
Monoalkyl Phosphates (MAP): e.g., monolaurin phosphate. Less irritation, mild, easy to rinse, rich foam and other advantages. Reduces irritation and tightness when compounding soap-based formulations.
Tightness:
The feeling of tightness after washing is generally related to the deposition of table live on the skin and the amount of skin oil that is washed off.
Degree of Tightness: Sodium Lauryl Sulfate (SLS) > Sodium Lauryl Ether Sulfate (SLES-2) > Tetradecanoic Acid Soap > Alkyl Phosphates
Amino Acid Surfactants
Amino acid surfactants also fall under the category of anionic surfactants.
Advantages are good skin friendliness, mostly weak acidity, extremely mild, non-irritating, the stimulation of injured skin is similar to water, moderate fat-washing ability, not easy to deposit in the skin, not tight after use, but easy to wash the face did not wash the feeling.
Recognition of a formula can be applied: fatty acids + acyl + amino acids + salt. For example: sodium lauroyl glutamate, cocoyl glutamate TEA salt, potassium cocoyl glycinate, methyl cocoyl taurine sodium, N-lauroyl sarcosine sodium, and so on.
Amino Acid Surface Activation is suitable for medium to dry skin types. As the degreasing ability is not up to the requirements of oily skin types, it is not highly recommended for oily skin to avoid skin problems due to insufficient cleansing power.


Tips:
Amino Acid Facial Cleanser is a facial cleanser with amino acid surfactants as the main cleansing ingredient, not just an amino acid ingredient in a low-foaming formula. Acylated amino acids are already different from normal amino acids, so please screen carefully when shopping to prevent buying fake amino acid cleansers.
Amphoteric surfactants
Betaine and its derivatives: e.g. Cocamidopropyl Betaine (CAB). Low skin irritation, medium degreasing ability.
Nonionic surfactants
Alkyl Glycosides (APG): Prepared by direct glycosidation of glucose with long chain fatty alcohols. Known for its minimal irritation to the skin and eyes, it also has a good washing effect, and can reduce irritation by compounding with certain irritating surfactants. Synthesized with natural raw materials, it degrades quickly and thoroughly, which is good for the environment. From this point of view, there is almost no other table activity on the market.
By now, you should have discovered that the choice of facial cleanser is based on the amount of oil in your own skin as the main reference, no matter whether it is winter or summer, south or north, you have to consider the amount of oil in your own skin recently. For example, some girls with normal skin have a little more oil on their skin in the summer.
Although the table living is the key to face wash skin irritation, but no matter which kind of face wash, amino acid or, alkyl glycoside or, soap-based or, there is no absolute good or bad, are to suit the purpose of their skin type to choose.
After the use of skin care products to pay attention to the changes in their skin, some of the heart of the oily skin girl, obviously has grown a face of occlusion, but also in the superstitious amino acid facial cleanser, then I have to cry for you to cry ~!
