What are the development and application prospects of alkyl polyglycosides?
2020-02-29 10:50:25

Alkyl polyglucoside is white powder, and the actual product is cream or light yellow, which has no obvious melting point. Soluble in water 'glycol' pyridine, insoluble in general organic solvents, the solubility in water decreases with the extension of alkane chain, and increases with the increase of degree of polymerization, so the solubility at room temperature is large, which has no effect on application. Water solubility is produced by the hydrogen bond formed by multiple hydroxyl groups on sugar, while the interaction of hydroxyl groups in water is very different from that of alcohol ether bond in water, So there is no cloud point and dilute gel as non-ionic surfactant.


Alkyl polyglucoside


1) foam properties: foaming properties between anionic and non-ionic surfactants, which can be high and low, but the foam is fine and stable. After comparing the foam structure, it is found that the bubbles are irregular polygons, big and unstable, and the foam layer is thin and dry, while the foam is smaller, showing a hexagonal structure similar to the benzene ring structure, and the foam layer is moist, so it is stable and smooth, with alkyl chain length. The carbon content is high in foam performance, and its foam performance is also related to the value of R. However, the regularity of this relationship has not been found yet.

2) Decontamination power: the decontamination power increases with the increase of alkane chain. When the carbon number is, the decontamination value reaches a large value, and then decreases rapidly. This is because the solubility in water is very small, which does not mean that the decontamination power is poor.

3) viscosity increasing: it has the function of increasing viscosity, and the viscosity increasing ability of monoglycoside can even be compared with the commonly used tackifier alkanolamide. When alkanolamide is used, it may produce nitrosamines, so it has broad prospects as nitrogen free tackifier. Experiments have proved that when used as a formula component, it is no longer necessary to use tackifier, and has no adverse effect on foam.

With the continuous improvement of safety requirements for cleaning products, the increasing depletion of oil resources, rising prices, and excellent development performance, natural, mild and renewable new surfactants have become a major research topic for scholars at home and abroad. Alkyl polyglucosides are the condensation products of sugar compounds and higher alcohols, and raw materials are starch, oil and derivatives of plant renewable resources Glucose and aliphatic alcohols are new generation of mild, green surfactants. They are non-ionic, but have no cloud point. They have no gel range after dilution in water, and are potential alternatives to many advantages of non-ionic and anionic surfactants. They are used to prepare high quality products with excellent ecological, toxicological and skin properties, and there are no safety and environmental problems. Great development and application prospect. At present, it is being used in washing industry, cosmetics industry, food processing industry, pharmaceutical industry and many other fields at a very fast speed.
