Alkyl polyglycoside refers to an alkyl polyglycoside synthesized with glucose and fatty alcohol (Alkyl Polyglycoside. APG for short). It refers to a glycoside with a sugar unit greater than or equal to 2 in a complex glycoside compound, collectively referred to as alkyl polyglycoside (or alkyl polyglycoside) . In general, the polymerization degree n of the alkyl polyglycoside is in the range of 1.1 to 3, and R is a C8 to C16 alkyl group. APG is a white solid powder or light yellow oily liquid at room temperature. It has high solubility in water and is difficult to dissolve in common organic solvents.

Alkyl polyglycoside has low surface tension, no cloud point, adjustable HLB value, strong wetting power, strong detergency, rich and delicate foam, strong compatibility, non-toxic, harmless, non-irritating to the skin, rapid and thorough biodegradation, It can be compounded with any type of surfactant, and the synergistic effect is obvious. It has strong broad-spectrum antibacterial activity, the product has a significant thickening effect, is easy to dilute, has no gel phenomenon, and is convenient to use. And it has strong alkali resistance, strong acid resistance, hard water resistance and salt resistance. It can be used as the main raw material for daily chemicals such as shampoo, shower gel, facial cleanser, laundry detergent, hand soap, dishwashing liquid, vegetable and fruit cleaning agent. It is also used in synthetic detergents such as soap powder, non-phosphorus detergent, and non-phosphorus detergent. It can be used as emulsifying and dispersing agent for food, pesticides, and silicone oil; synergist for pesticides and herbicides; antifogging agent for agricultural film, plastic additives; also used for 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 (does not contain toxic by-product dioxane), mildness and antibacterial properties. It conforms to the future development direction of personal care products and will replace existing petroleum-based surfactants as the mainstream surfactant.
APG can also be used to prepare solid dispersions and plastic additives. Although APG is a stable compound, the remaining three hydroxyl groups on the sugar group can be used to further synthesize various esters and other derivatives (such as ethers). If APG is connected with carboxylic acid or other acid, various anionic esters of APG can be prepared, such as sulfosuccinate, citrate, tartrate, maleate, sulfate, phosphate, etc. The first three esters are available in foreign markets. They have good foaming properties, compatibility, mild to the skin, non-irritating to the eyes, and do not contain dioxane, ethylene oxide and nitrosamines, so they are very suitable Used in cosmetics and personal protection products. In addition, APG can also synthesize alkoxylates and quaternary ammonium cation SAA.
