The foam eliminating agent can be discharged in a liquid film, so the rate of foam can reflect the stability of the foam, adding a substance to accelerate the foam discharge, or the role of foam elimination. Adding a hydrophobic solid particles can break the bubble? The hydrophobic solid particles in the surface of the bubble surface will attract the hydrophobic end of the surface active agent to cause hydrophilic particles to produce hydrophilic and aqueous phase, thereby exerting a defoaming effect. The solubilized foam surfactant can destroy some low molecular materials that can be completely mixed with the solution, and can increase the solubility of the foam surfactant to effectively concentrate. The low molecular material such as octanol, ethanol can not only dissolve the surfactant concentration of the surface layer, but also dissolve the tightness between the surfactant adsorption layer, the surfactant molecule, thereby reducing the stability of the foam.
This is because their surface and interior are uniform, not enough to form an elastic film, even if it is unstable, it will disappear immediately. However, when there is a surfactant in the solution, since the molecular energy and use, the hydrophilic group and the hydrophobic group in molecules are adsorbed by the bubble wall, forming a regular arrangement, and the hydrophilic base surface, the hydrophobic base surface, thereby The flexible film is formed in the bubble interface, the coordination is strong, and it will not rupture it normally. The coordination of the foam is related to surface viscosity and elasticity, electricity, surface membrane, temperature, evaporation and other factors. another situation. Pure water and pure surfactants do not afford the bubble fragments substantially related to changes in the tension of the liquid, and the tension is small, the more easily foamed. In life and production, the emergence of bubbles will often bring a lot of inconvenience, so we must eliminate bubbles.
Conclusion: The washing powder is similar to the laundry powder, and the effective ingredient is a surfactant. The difference is that the laundry powder is an anionic surfactant, the alkaline is large, clean, stimulating the skin, washing powder is a nonionic surfactant, neutral, enters Naturally relative to laundry powder is faster, high hydrophilicity is more easily flushed. Laundry powder is gently mild, stimulated, the corresponding contrastability is weak, and the damage to the clothes is smaller.
When the fabric of the dirt dirt enters the water containing the detergent, the surfactant works. One of the ends of the ionized and enters the oil. One end of the hydrophilic water should jointly pull the oil from the surface of the fabric into the water, and the oil on the surface of the fabric is slowly loose. Then, under the action of the water flow impact, manual friction, the dirt is wrapped by a surfactant, suspended from the surface of the fabric in aqueous solution, and the surfactant quickly occupies the surface of the fabric, preventing the dirt from being deposited again, then rinse with water.
A small number of conscience washing cream uses a mild amino acid surfactant (XX oleo + XX amino acid + potassium / sodium). This surfactant is more expensive, and the process is more troublesome. In order to avoid precipitation problems, facial cleanser, especially men's face, rarely.
The viscosity of shampoo is very high. As a medical anti-off hair, it is advantageous that natural surfactants do not impair the scalp or hair and form a natural protective film. This is an important factor in distinguishing general shampoo. The chemical surfactant has a strong cleaning force, but it will damage the hair and scalp.
Look at whether the ingredient table contains amino acid surfactants. The maximum feature of the surfactant is that at both ends of the molecule, one end is a hydrophobic group and the other end is a hydrophilic group. The hydrophilic end of the amino acid surfactant is an amino end of the amino acid, and the other end is a hydrophobic end (mostly a fat chain).

Product use: As an important surfactant, monomer and industrial cleaning and electrolysis.
Dimethyl Didecyl Ammonium Chloride supplier Oil, the cleaning performance is good. Other industries are used as emulsifiers, wetting agents and penetrants.

As for the remaining three very mild surfactants, it is surprising that the sodium methyl coconut oxyl talades in the sorghum of the sorghum is a new type of amino acid surfactant, usually only used for preparation. High-grade cosmetics and infant products, so this washing is said to be sincere.
The amino acid surfactant, the amphoteric surfactant and the nonionic surfactant are both mild surface active ingredients, and the stimulation of the skin is relatively low. Among them, amino acid surfactants have gentle and good cleaning capabilities, so they are widely welcomed.
