Alkyl glucoside, abbreviated as APG, is synthesized from renewable natural fatty alcohol and glucose. It is a new type of non-ionic surfactant with comprehensive performance. It has the characteristics of common non-ionic and anionic surfactants. It has high surface activity, good ecological safety and miscibility. It is internationally recognized as the preferred "green" functional surfactant.

Alkyl polyglycoside has low surface tension, no cloud point, adjustable HLB value, strong wetting power, strong decontamination power, rich and delicate foam, strong compatibility, non-toxic, harmless, no stimulation to skin, rapid and complete biodegradation, and can be compounded with any type of surfactant with obvious synergistic effect. With strong broad-spectrum antibacterial activity, the product has remarkable thickening effect, is easy to dilute, has no gel phenomenon, and is easy to use. Moreover, it has strong alkali resistance, strong acid resistance, hard water resistance and salt resistance. It can be used as the main raw material of daily chemical industry, such as shampoo, shower gel, facial cleanser, laundry detergent, hand sanitizer, tableware detergent, vegetable and fruit detergent, etc. It is also used in synthetic detergents such as soap powder, phosphate free detergent and phosphate free washing powder. It can be used as emulsion dispersant for food, pesticide and silicone oil; Synergist of insecticides and herbicides; Agricultural film antifogging agent, plastic additives; It can also be used in medicine, bioengineering, industrial cleaning, fire-fighting agents, textile additives, coatings, photosensitive materials, tanning, oil extraction, mineral processing, rubber and plastics, energy and other fields.

APG has advantages in product safety (excluding toxic by-product dioxane), mildness and antibacterial property. It conforms to the development direction of personal care products in the future and will replace the existing petroleum based surfactants as the mainstream surfactants.

APG can also be used to prepare solid dispersions and plastic additives. Although APG is a stable compound, it can be used to further synthesize various esters and other derivatives (such as ethers) from the remaining three hydroxyl groups in the sugar group. If APG is connected with carboxylic acid or other acids, various anionic esters of APG can be prepared, such as sulfosuccinate, citrate, tartrate, maleate, sulfate, phosphate, etc. The first three esters can be purchased in foreign markets. They have good foaming property, compatibility, are mild to skin, do not irritate eyes, and do not contain dioxane, ethylene oxide and nitrosamine, so they are very suitable for cosmetics and personal protection products. In addition, APG can also synthesize alkoxylates and quaternary ammonium salt cationic SAA.

APG can be stored for a long time in a large temperature range. At the same time, it has the function of humidification, which fully meets the performance requirements of active components for cosmetics. APG has been used as an active component in cosmetics at home and abroad. This new type of cosmetics shows good skin moisturizing and skin curing properties. At present, there are still some quality problems in cleaning agents for human body. The most serious one is that they contain excessive toxic substances, such as Hg, Pb and as, which not only seriously damage the skin and hair, but also pollute the environment. The new generation of shampoo and bath liquid made with APG as the base agent has great foaming power. The foam is white and delicate. It has a soft effect on the skin, no irritation to the eyes, no pollution to the environment, good resistance to hard water, and has good recuperation and maintenance functions. It is especially suitable for preparing high-grade toilet products.

In shampoos, APG has no irritation to human skin and eyes, and can also reduce the irritation of other active agents compounded with APG. Therefore, it is one of the essential raw materials in low irritation shampoos and children's shampoos. The gentleness of APG has a protective effect on damaged hair, and can be used as an active agent for hair dyeing and perming, The shaping performance of the mixture with protein hydrolysate is comparable to that of the commonly used shaping agent polyvinylpyrrolidone, and it is easier to rinse. APG can be used to prepare a new generation of shampoo and bath liquid, with strong foaming power and fine foam.
