There are many unique advantages about alkyl polyglycosides

Alkyl polyglucosides can be applied in many industries and fields, such as washing, cosmetics, food processing, textile printing, pesticides and pharmaceuticals. As a raw material for non-ionic neutral detergents, they have broad application prospects. For high-grade clothing cleaners. In addition, alkyl polyglucosides have a broad spectrum of antibacterial activity against Gram-negative bacteria, Gram-positive bacteria and fungi.

As a novel nonionic surfactant, alkyl glycosides have many unique advantages. Such as: and anionic surfactants have obvious synergistic effects; rich in foam; less irritating to the skin; non-toxic and good biodegradability, etc., so that alkyl glycosides have certain properties in the formulation and application of daily chemical products. Superiority, which has been widely used.

Alkyl polyglycoside (Alkylpolyglycoside APG) is a mixture of alkyl glycosides or alkyl polyglycosides, which are derived from renewable resources (starch or glucose and natural fatty alcohols) and lose one molecule of water under the catalysis of acid. It is a general term for a compound with a sugar unit ≥ 2 in a complex glycoside compound, and can also be represented by [G]nOR, G is a glucose unit, n is the number of sugar units, and n=2, 3, 4, and 5 glycosides are alkyl polyglycosides, R It is an alkyl group of C8 ~ C16.

Alkylpolyglucoside (APG) is a plant-derived green surfactant which is formed by dehydration of an alcoholic hydroxyl group of a fatty alcohol and a hemiacetal hydroxyl group of glucose under the action of an acidic catalyst. Because it is synthesized from renewable plants, it is not only mild in performance, non-toxic, but also completely biodegradable. It has excellent environmental friendliness. It is a traditional surfactant alkylphenol and fatty amine polyoxyethylene ether. One of the desired alternatives is sustainable compared to petrochemicals and is therefore considered a new generation of green surfactants after soap, LAS, AEO and AES.

Surfactants are important materials in the processing and application of pesticides. For the selection of surfactants, not only must they be compatible with pesticides, but also take into account factors such as synergy, stability, price, safety, etc., so that they can be better applied after being sprayed with crops. The role of pesticides. As humans become more demanding on the environment, the demand for surfactants is becoming more stringent. Some pesticide surfactants, although low in price and excellent in emulsifying properties, have been widely used at home and abroad, but they are difficult to biodegrade in the natural environment and have adverse effects on aquatic organisms. Therefore, from the perspective of environmental protection, combined with the current trend of pesticide development, strengthen the research strength of surfactants, accelerate the development of new varieties that are beneficial to biodegradation, especially surfactants for water-based pesticide formulations, and strengthen the surface of pesticides. The management of active agents provides a safe, environmentally friendly, compatible and effective surfactant for pesticides.
