Adsorption of surfactants and polymer components in shampoo water is co-happening through static electricity and hydrophobic. The hair surface has a negative charge under the pH of the shampoo. Any substance with positively charged, such as cationic surfactants or cationic polyelectrolytes, will be adsorbed by electrostatic interaction between the negative group and the surfactant head base.
Therefore, the surfactant continues to evolve. One is to abandon sulfate, select amino acid as a surfactant, that is, the current epidemic amino acid shampoo. The irritation of amino acid surfactants (such as sodium coconut phosphose, sodium lauryllaria, sodium lauryllaria, etc.) is only 20% to 40% of SLS (different types will have a difference), which is the mainstream choice of high-end products. However, these products also have a disadvantage that cleaning is not as good as sulfate, and the production cost is much higher than that of sulfate, and the product is relatively thin, and the shampoo is large.
Cleansing milk. Clean soap. Clean gel .. How to choose a cleansing product? In general, the cleansing products are divided into surfactants and soap-based cleaners based on ingredients.
For the active welding of aluminum alloy, this test explores a new active agent introduction method, coating the active agent in the surface of the aluminum alloy wire or filled into an aluminum tube, preparing an active coating wire and an active pharmaceutical core welding wire, and then active TIG welding. The formation of the weld surface was observed by experiment. Welding is deep. Weld tissue, etc., analyze the characteristics of active wire.
Low foam surfactants are the basic requirements of home washing (household dishwasher detergent). Natural, safe, gentle is the foundation of industry-benign development, easy to rinse. No bitter taste is a selling point for industry brands. Disinfection Antibacterial is a major demand in an epidemic prevention.
The conventional surfactant molecular weight is low, and the surface area of the particles is generally not completely covered with surface separation, upward transfer, resulting in increased particle adhesion during flocculation and storage. In general, the dispersion capacity of the surfactant depends on the type of molecular weight and the illegitimate group. In order to improve the long-term stability of the preparation, the molecular weight of its surfactant is increasing when the aqua-based surfactant is used as an emulsifier and a dispersant.
Sodium lauryl ether sulfate factory This is because although the molecular weight of the hydrogen-based surfactant diffuses to the surface of the particles slower, the adsorption capacity is strong, and it is not easy to transfer and fall off from surface transfer, and provides long-term stability.
Shampoo contains 10-20% surfactant. This concentration is very high. If you use some water to wipe the water, the foam will rise. This is the surfactant contributes to stabilizing bubbles.
An ingredient that mutually fused with the oil and water. Interfacial active agents are indispensable to dissolve oil and water, and it is essential when dissolved in water. Cosmetics of water and oil fusion cities will contain interface active agents such as emulsions and creams. The interfacial active agent is dissolved to fuse it with water, and naturally dissolve the moisturizing ingredients of the skin surface. If you use too much, the skin will become rough. However, the interface active agent is also divided into different types, and the stimulation intensity of the skin is also different. In addition, the skin surface itself also contains a natural interface active agent, which emulsifies sesaceous and water to protect the skin. 4. Moisturizer · Multoxy compound.
Surfactant: means that a small amount of substances can significantly change the state of the solution system.
SLES manufacturer Surfactants are divided into ion surfactants (including cationic surfactants and anionic surfactants). Non-ionic surfactants. Popular surfactant.
Sodium Lauryl Ether Sulfate supplier Composite surfactant. Other surfactants, etc. It is mainly composed of a surfactant having a washing effect. The pH is close to the skin pH, gentle smooth, but if the compound is not good, it is easy to make a feeling of clean.
Amino acids are the basic unit of protein. Amino acid surfactants are amino acids (such as glutamate, glycine, etc.) salts (such as glutamate, glycine, and tetraolamine salts). Therefore, the use of amino acid washing can repair the hair and nourish the scalp.
