Alkyl polyglycoside "green" functional surfactant
2017-10-12 11:26:14

A product obtained from the hemiacetal hydroxyl group and the fatty alcohol hydroxyl group of glucose, which lose one molecule of water under the catalysis of a strong acid. The synthesized alkyl polyglycoside contains a large amount of free fatty alcohol and cannot be sold as a product. It needs to be refined. The APG produced by using C8-C10 alcohol and C12-14 alcohol is water-soluble, and the refining is mainly to remove the free fatty alcohol (in order to obtain the desired The product distribution, fatty alcohol is often greatly excessive), free alcohol will significantly affect product performance and application; generally refined product fatty alcohol content is less than 1%; AMG after dealcoholation should be decolorized, and adjust PH and active content, and prevent Microbial growth, currently mainly using peroxide oxidation bleaching method, after bleaching, adding reducing substances to decompose residual hydrogen peroxide and adding preservatives such as methylparaben.

Alkyl polyglycoside surfactant, synthesized from renewable resources natural fatty alcohol and glucose, is a new comprehensive nonionic surfactant with both nonionic and anionic surfactants and high surface activity. Good ecological safety and compatibility are internationally recognized as the preferred "green" functional surfactants.

However, it is similar to conventional surfactants, usually strongly alkaline, and has a poor cleaning ability for nonionic surfactants. Most of the alkyl glycoside surfactants have higher viscosity, the appearance is viscous liquid or semi-solid (active content is about 50%), easy to be thickened, because the price is higher than the traditional surface, and the detergency is slightly Inferior, more than AES, CAB and other complex use.

China's surfactant industry began in the 1950s and has long been used mainly in the production of synthetic detergents.

With the intensification of market competition, manufacturers have shifted their focus to industrial surfactants. The increase in the consumption of industrial surfactants has also led to the rapid development of China's surfactant industry. Especially in the last 20 years, China's surface activity The agent industry is in a state of rapid development. The alkyl polyglycoside developed in the late 1980s and early 1990s is regarded as a world-class surfactant by domestic and foreign experts.
