The critical micellar concentration is one of the important parameters of the surfactant, leading solubilization, cell dissolution, and its interaction thereof, and the like. In general, the chain length (increasing hydrophobic) of the tail of the hydrocarbon is increased (increasing hydrophobic) will reduce the CMC value of the surfactant solution to increase its surface activity. Amino acid-based surfactants typically have a lower CMC value compared to conventional surfactants. Emulsifier (surfactant) has a lipophilic and hydrophilic group on the same molecule, so if you want to enter the oil phase, you will be dragged by the hydrophilic group. If you want to enter the aqueous phase, you will be dragged by the bartender move. Only on the oil / water interface, the ionized group enters the oil phase, the hydrophilic group enters the aqueous phase, in order to suit its, the lowest energy.DODMAC manufacturer  This is the essence of the surfactant spontaneously inclined to the esphiphilic of the oil / water interface.Dimethylbis(N-octadecyl)ammonium chloride supplier  The nonionic surfactant has a strong self-polymerization, so it is easy to form an orderly, dense interface film in the oil / water interface, which is advantageous for the stability of the emulsion. The size of the emulsion conversion point and the droplets appear to depend on the solubility of the surfactant in the alkyd and the aqueous phase. When using a nonionic and hydrophobic anionic surfactant, the size of the droplets is small and the temperature is less affected by the temperature of the droplet. ● Cleaning properties: consist of a variety of surfactants and additives. Surfactants typically have functions such as wetting, penetration, dissolution, thereby playing a function of cleaning and removal. Products using amino acid surfactants can be adjusted to a weak acid pH rather than their own ingredients. Typically, the foam of the amino acid surfactant product is small and is not intensive enough. People who like thick foams may be more disappointed. Only by the foam network can be achieved. Other products indicate the use of amino acid surfactants, but only add a small amount of such ingredients. We should pay more attention. Non-ionic surfactants are the most commonly used surfactants such as OP emulsifiers having good emulsification; anionic surfactant dodecyl sulfate is also effective. At the time of composite surfactants, it should be noted that the anionic surfactant cannot be mixed with the cationic surfactant, otherwise precipitation and failure will occur after each other. The antifoaming agent acts in the formation stage or after the foam thin layer: the antifoaming agent penetrates into the foam elastic film, which is distributed in the film, by reducing surface tension, causing thin layer rupture; or forming a single molecular film, making it adhesion, easy The thin layer rupture; the hydrophobic particles contained in the defoaming agent reach the surface of the thin layer, adsorb the surfactant on the top of the thin layer, so that the thin layer is broken due to lack of surfactants. And heavy oil cleaning agent. It consists of a variety of surfactants, penetrants, and additives, with penetration, emulsification, dispersion, and peeling. It is developed for the production process of metal parts during the machining process, which has a good cleaning effect on oil, oil and mixed dirt. It is judged whether it is an amino acid washing face, and it is checked whether the product contains an amino acid surfactant, whether these amino acid surfactants are ranked prior to the primary foaming agent. The fact is that most sunscreen does not need to make makeup products.Dioctadecyldimethylammonium chloride factory  Essentially, the makeup product and cleaning products are the same. They use surfactants to remove oils, powders, and other ingredients attached to the surface of the skin. However, due to the different types of surfactants, the cleaning capacity of the makeup remover is generally strong. The remover is mainly to clean the skin oil, the main components of sunscreen: sunscreen + water, less oil, easy to clean. In general, cleaning products can be removed. In the market, 80% of shampoo has such a surfactant. Many articles are unfriendly of this ingredient, saying that it will stimulate the scalma, allergies, etc., and even cancer.
