When surfactants are adsorbed on the metal surface, their hydrophilic groups are adsorbed on the metal surface. Due to the different properties of hydrophilic groups, they are physically or chemically adsorbed on the metal surface. The adsorption of different surfactants on the metal surface follows different adsorption isotherms.

Reactive flame retardants participate in the polymerization reaction as a monomer, so the polymer itself contains flame retardant components. Its advantage is that it has little impact on the service performance of polymer materials and has long flame retardancy.

Alkyl glycosides have good surface and interface properties. APG is a moisture-absorbing solid, which is generally dissolved in water and difficult to dissolve in some common organic solvents. However, it has good solubility and surface activity in acid solution, and its solubility and surface activity in alkali solution are more prominent than other non-ionic surfactants. When in use, it can be prepared into a stable inorganic salt active solution with a concentration of 20% ~ 30%.

Using the green non-ionic surfactant alkyl glycoside as the main raw material and deionized water as the solvent, a new type of green clothing cleaning wipes with excellent decontamination effect and friendly to the environment was developed. The properties of surface tension, stability and decontamination when compounded with other surfactants were investigated.

Due to the different flame retardant mechanism of various flame retardants, it is difficult to achieve the ideal effect by using a single flame retardant. Composite flame retardants are usually used.

The impact of surfactants on food safety can mainly include two aspects. On the one hand, surfactants themselves are enriched in animals and plants, and show their own toxicity with the accumulation of food chain in human body; On the other hand, the existence of surfactants accelerates the absorption of other toxic substances by plants, resulting in harm to food safety production.

Firstly, it comes from renewable plant resources, which is conducive to the protection and saving of limited resources. Secondly, the products made from it can be 100% biodegradable in the environment and re-enter the natural cycle. The biodegradability test shows that this degradation process is fast and complete. According to the internationally recognized OECD Test method, all tests show that APG has excellent primary biodegradability and final biodegradability. Alkyl glycosides do not harm the environment under all environmental conditions and have excellent environmental compatibility.

What are the advantages of surfactant synergistic repair technology? Surfactant synergistic remediation technology has become a very potential remediation technology of organic soil pollution. It mainly uses the solubilization of hydrophobic organic pollutants by surfactant solution to promote the desorption and dissolution of organic pollutants adsorbed on soil particles, and finally move out of the soil environment, so that the soil can be repaired. In the technology of bioremediation of contaminated soil, adding an appropriate amount of surfactant when necessary can disperse microorganisms and promote growth.

In the preparation process of down jacket cleaning wipes, the effects of different ratios on the performance of wipes were observed. Combined with the use feeling and decontamination effect of wipes, it was considered that formula 5 was better when the mass fraction of green non-ionic surfactant alkyl glycoside (APG) was 12%, the mass fraction of surfactant AEO-9 was 5%, and the mass fraction of SCA was 3%.

People usually evaluate their detergency effect through the foaming volume of detergent. The rich and delicate foam will contact with the stains on clothing more extensively to achieve the effect of decontamination. But contrary to the conventional thinking, the more foam is, the better the decontamination effect is. It is evaluated by active molecules, and with the increasing popularity of environmental awareness, At present, low foaming or non foaming detergents are more popular.

From the development trend of surfactants, products with ecological safety, no environmental pollution, strong functionality and low cost are more and more favored by people. Alkyl glycosides are new surfactants in line with this development trend. According to the research, the acute toxicity of APG is very small. The acute toxicity LD is 1000-15000mg / g, the aquatic biological toxicity LD50 is 3-101mg / L, and the biodegradation rate can reach 93.94%.

PP halogen-free flame retardant is a special environment-friendly flame retardant for PP, which belongs to nitrogen phosphorus flame retardant. It is a halogen-free and intumescent flame retardant specially developed for polypropylene. It is polymerized by phosphorus and nitrogen containing chemicals with synergistic effect. It has good compatibility in polypropylene, has little impact on the mechanical properties of plastics, and has excellent processing stability in the processing process.

As a green multifunctional nonionic surfactant, alkyl glycoside has become an important raw material in daily washing industry. In the selected system, the preferred alkyl glycoside is apg1214, and the preferred dosage is 10%. Under these conditions, the addition of alkyl glycosides not only significantly improves the fluffy, softness and antistatic properties of laundry solution, but also has a synergistic effect on the detergency of laundry solution. With the deepening of research, alkyl glycosides will be more and more widely used in laundry detergent.

Cosmetic surfactants are newly developed in recent years. They have higher and stricter requirements for products, such as anti-aging, skin moisturizing, wrinkle removing, whitening and so on. The active ingredients of cosmetics affect the metabolism of the body after being absorbed by the skin to achieve real beauty. The effect should be felt or seen.

The adsorption of surfactants on dirt and the surface of washing articles (from solution) has an important impact on the washing effect. This effect is mainly due to the change of interface and surface properties (such as mechanical, electrical and chemical properties) caused by adsorption.

Cosmetic surfactants are newly developed in recent years. They have higher and stricter requirements for products, such as anti-aging, skin moisturizing, wrinkle removing, whitening and so on. The active ingredients of cosmetics affect the metabolism of the body after being absorbed by the skin to achieve real beauty. The effect should be felt or seen. Sodium pyrrolidone carboxylate (PCA) is a natural moisturizing factor of cosmetics, which has the effects of anti-aging and wrinkle removal. Therefore, PCA is widely used in high-grade cosmetics. Surfactant as emulsifier is very important in emulsion application of cosmetics, mainly concentrated on non-ionic surfactant and polymer emulsifier. Cosmetic emulsion includes double emulsion. W/O, O/W, liquid crystal phase, multiple emulsion; W/O/W, O/W/O, microemulsion and so on. The main products are facial cleanser, moisturizer, cleaning milk, etc. There will be new products coming out in this field.

The properties of alkyl glycosides vary significantly with the alkyl chain length, so the alkyl chain length has a great influence on its application in laundry liquid. At the same time, the amount of alkyl glycosides is also an important factor affecting the quality of laundry detergent.

The development of compound surfactants is suitable for the needs of a variety of pesticide formulations. At present, there are many studies on the compound system of 2 ~ 3 surfactants in China, and there are few studies on the compound system of more than three surfactants. The development of multi surfactant complex system is a new direction of dispersion system research.
