APG is a moisture absorbing solid, which is generally dissolved in water and difficult to dissolve in some common organic solvents, but 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%.

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.

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.

Alkyl glycosides are non-toxic and non irritating to human body, and biodegradation is rapid and complete. The final products of degradation are carbon dioxide and water, which has good ecological safety and compatibility. The green characteristics of alkyl glycosides make it have great advantages in the application of laundry detergent.

Alkyl polyglucoside (APG) is a mild surfactant developed in the world since 1990s. These surfactants can be synthesized from renewable plant resources. They not only have broad-spectrum antibacterial activity, but also have the advantages of rapid and complete biodegradation and no pollution to the environment. This paper attempts to take two typical red tide organisms, Prorocentrum dentatum 0201-01 and red tide heterobay algae, as examples to explore the effect of APG surfactants on the growth and killing of red tide organisms, in order to lay a foundation for the development of the application of these compounds in the control of harmful red tide.

In addition to changing the activity of the solution in aqueous solution, that is, reducing its surface tension, various properties related to washing, such as penetration, adsorption, wetting, dispersion, emulsification, gelling and foaming, will change significantly near the critical micelle concentration.

Surfactant has low toxicity and irritation, and has mild bactericidal and algal inhibition effect, which can effectively control the over reproduction of algae. However, it will not cause excessive water transparency, and can effectively promote the improvement of water microenvironment. Because the above surfactants have some functional groups of vitamins and amino acids, it is actually observed that they can promote growth. For example, BS-12 not only has good growth promoting effect, but also has good water quality adjustment, bacteriostasis and algae killing function.

The synthesis methods of alkyl glycosides mainly include trans glycoside method, direct glycoside method, Koenigs Knorr reaction method, enzyme catalysis method and so on.

Surfactants play an important role in pesticide formulations. The new varieties of surfactants developed have also attracted the attention of the pesticide industry. By changing the varieties of surfactants to improve or change the original processing dosage forms of some pesticide varieties, the biological activity is improved, the dosage is reduced, the cost is reduced, and the compatibility with the environment is improved.
