A defoamer containing hydrophobic particles has a third mechanism. These hydrophobic particles begin to adsorb surfactants at the top of the thin layer to achieve the surface of the thin layer. Since the gradual disappearance of the surfactant, the foam is broken.
Shampoo is alkaline, the anionic active agent removes dirt on the hair; the conditioner is acidic, and the cationic active agent forms a protective film on the surface of the hair while not fully cleaned or better protection, so separate;
Therefore, for cleaning makeup oils of cleaning cosmetics, the makeup makeup usually uses two principles of oil-soluble oil and surface cleaning. Thus, a small amount, relatively mild surface activity and a certain oil are used. It can not only make the cleaning efficiency, but the residue of the surfactant can also be as small as possible, and the oil can also avoid drying of the skin contact surfactant.
The sesace, protein and starch dirt are easily attached to the clothes. These substances themselves are difficult to clean, sometimes even other substances are also difficult to clean. The enzyme detergent has a significant removal effect on these dirt, making the surfactant more easily remove dirt.
research shows. Foam eliminates the need for silica particles to promote a simple polydisiloxane foam inhibitory performance, with polydiloxane and polyethylene copolymer-based siliconethylene glycol foam eliminant. Due to its hydrophobicity, the silica particles are brought into the air water interface of the silicone oil to the foam and enter the foam film. Due to the synergistic effect, the foam is rapidly discharged, resulting in contact with the surfactant foam droplets, forcing the foam solution to discharge from the surface of the solid hydrophobic particles.
Dihydrogenated Tallow Dimethyl Ammonium Chloride factory These two ingredients have a good foam elimination effect. First, the polysiloxane foam eliminating agent has been widely used in textile dyeing due to its excellent foam elimination effect.

Amino acid surfactants have good wettability, foamability, antimicrobial, corrosion resistance, antistatic, and have a mild compatibility with other surfactants, and have been widely used in cosmetics, cleaning products and medical care. health.
The product line of BASF personal care products almost all raw materials of personal care products, main active ingredients, surfactants, sunscreen, emulsifiers, oil, polymers, etc. BASF's core research direction is mainly sunscreen, active ingredients and surfactants.
For nonionic surfactants, when the foam wall is diluted to a certain extent, the mixed entropy of the surfactant polyethylene glycol is too large, and it cannot penetrate each other, preventing the foam wall from further dilution.
Dimethylbis(N-octadecyl)ammonium chloride manufacturer Of course, this effect is only important when the foam is very thin.
The aqueous phase sealant is exclusively introduced with a composite surfactant system with a biological surfactant as the main body, so that the working fluid has hypertonautical, humid, and cleaning capability to ensure fast in-depth micropores in the functional substance.
The formation of emulsion: a large amount of surfactant has been added to the emulsion, which reduces the surface free energy of the system, and the surfactant molecule is adjacent to the oil-water interface, forming a interface film, preventing the collision between the oil droplets, so that the droplets can Long-term stably exists in water. Therefore, when the emulsion wastewater is treated, its stability, attempting or impairing the ability to stabilize the emulsion of the surfactant to achieve oil water separation.
