The ionic surfactant can be divided into an anionic surfactant. Cationic surfactant.
octadecanoic acid-2-hydroxyethyl ester supplier Some special surfactants.
Because it is mainly combined with water and detergents, the skin feels is also the most refreshing in all removal products. However, since the surfactant will take away the oil content of the skin surface when cleaning, the skin will feel dry and tight after the remover.
Instead of sap-based ingredients, the surfactant is the main raw material such as bebetoid. Alkyl glucose. Amino acid derivative, etc., these are very moderate components, very irritating, and there is also a certain effect in cleaning. I don't dry, I feel very smooth.

The surfactant is divided into ionic surfactants and nonionic surfactants (such as polysorbates. Monoglycerides) according to the molecular composition characteristics and the dissociation characteristics of the polar group. According to the charge of the ion surfactant, it can be divided into anionic surfactant (such as sodium sulfate, soap), soap). Cationic surfactants (such as Jiel, New Jeer off) and amphoteric ionic surfactants (such as lecithin).

2-Hydroxyethyl octadecanoate manufacturer Cleaning principle of water-based cleaning agent: a surface active agent containing surfactant. Emulsifier. Ostener, etc., to achieve metal surface oil. Fatness. Cleaning of cruising.
Sulfate / lauryl alcohol polyether sulfate sodium sulfate surfactant is less irritating to the soap group, and has a strong removal effect. Between which is between the soap group and the amino acid surfactant, there is a relatively suitable person between the two skin. Acne skin is greasy, sometimes acne. This cream can also be used in a short time.
The surface coverage modification method is to cover the surface of the surface of the surface, so that the surfactant or coupling agent is bonded to the surface of the particles by adsorption or chemical bond, so that the surface of the particles from hydrophilic to hydrophobic, granular nature Increase the compatibility of the particles to the polymer. This approach is the most common method. It can be understood that the surface active agent of the two-sex groups cover the particles, the hydrophilic group is facing the surface of the particles, and the hydrophilic group is good, and the polymer is compatible with the polymer. Modified destinates, expand the application range of talcum powder.
The soap group is an anionic surfactant, soap group cleaning is usually a cleaning product consisting of fatty acid + base. The component contains stearic acid. Fauic acid, compared with amino acids, soap-based cleaners are characterized by rich foam. Soap group has strong cleaning ability and degreasing ability. Excessive use of soap groups, especially those who are sensitive to skin, and those who dry skin are prone to problems. Oil skin should not excessive use of soap group cleaning, and you can use it in summer evening. Most of the soap group is some highly clean facial cleanser, exfoliating. It is not the use of two or three large oil fields that can effectively remove impurities on the skin.
For allergic skin, it is recommended to use anti-allergen washing milk, amino acid washing milk is also a good choice. Excessive frozen milk often contains more anionic surfactants, large alkaline, high pH, large irritability, not suitable for use.
Answer this question, we need to start from the main components of shampoo. Our hair is exposed to a natural environment, and a lot of oil is deposited on the scalp. Drop the scalp. Dust and other dirt in the environment. Since oil is insoluble in water, the main ingredient added to shampoo is an anionic surfactant that can remove oil. However, since the anionic surfactant in shampoo is alkaline, while removing oil, it can cause hair scales to open, so that the hair is dry and irritated.
