The main ingredient of the conditioner is a cationic surfactant. After shampooing, use anionic surfactants that neutralize shampoo residue and help close cuticles for a lustrous finish. But this closure is also temporary, the hair swells in the water and the damaged cuticles open, so only the use of conditioner can temporarily make the hair smooth and shiny.
As I said before, scalp health is very important. Scalp health has a lot to do with regularly used shampoo ingredients. You may have heard that shampoos contain bad silicon content, but in fact, the key to determining the quality of shampoo ingredients is not the silicone oil, but the surfactant.
August 4, 2016 Harmful foam is generated during biological water treatment. The main causes of foam formation are as follows: foam formation at the beginning of process operation, denitrification foam, surfactant foam and biofoam. The appearance of harmful foam covers the surface of the aeration tank, which brings difficulties to the operation and management of the biochemical field, and also deteriorates the quality of the effluent.
Dioctadecyldimethylammonium chloride factory Distearyl Dimethyl Ammonium Chloride manufacturer Therefore, it is necessary to eliminate harmful foam in biological treatment, many people have biological defoamer
Zwitterionic surfactants are positive and anionic, respectively, with little irritation, easy to dissolve in water, good stability under acid and alkali conditions, more foam, strong detergency, can effectively dissolve skin oil, remove old waste keratin, dredge Pores, make skin pores clean and transparent.
(1) Fourier transform infrared spectroscopy study found that the infrared characteristic curve of carbon nanotubes is the same as that of surfactants, and the surfactants are indeed adsorbed on the surface of carbon nanotubes.
Soap and detergent are not the same thing at all. The main chemical ingredient in soap is sodium stearate, which was invented 5,000 years ago. Sodium stearate is a surfactant. As for what is a surfactant, you can refer to Q5 of the 199th issue. Of course, the main ingredients of detergents are also surfactants, but their composition and formulation are more complex.
Keyan's white clay series has always been very popular. The surfactants added to this facial cleanser are betaine and sodium cocoyl glycinate, and the soap-based ingredients are relatively mild.
Mineral oil defoamers usually consist of a carrier and an active agent. The carrier is a material with low surface tension, which has the function of carrying and diluting. Commonly used carriers are water, fatty alcohol and the like. ; The role of the active agent is to inhibit and foam, and the commonly used materials are waxes, fatty amides, fats, etc. , Changqing defoamer price custom processing.

From this study, it can be found that medical fabric laundering in the United Kingdom relies primarily on the application of heat; laundry treatment in the United States has long relied on recommendations from the Centers for Disease Control and Prevention: the laundering process is the result of a combination of mechanical, thermal disinfection and wash chemistry factors. Dilute and agitate the water to remove large amounts of microorganisms. The role of detergents and surfactants is to suspend soils, reduce the surface tension of water, and inhibit certain microorganisms.
Since amino acid facial cleanser is very good for our skin, how to distinguish real and fake amino acid facial cleanser? This depends not only on whether the amino acid is marked in the ingredient list, but also on the first few surfactant ingredients.
