Application:

Usage of 2.6-di-o-methyl-beta-cyclodextrin

Can increase the solubility of the pharma and biological availability.

Can add up the good effect and decrease the dose.

Can control or adjust the reactive speed, lower the toxicity and enhance the stability.

Especially 2.6-dimethyl-beta-cyclodextrin is more effective for the oil-soluble molecules of water-soluble.

Characteristics of Methyl Beta Cyclodextrin and Its Application in Coating Thickener

Pakcage:1kg/bag or 20kg/drum

Storage: Keep in a tightly closed container and store in a cool, dry, dark, ventilated area. When the temperature is higher than normal temperature, the

product is easy to melt and cause caking. If caking occurs, it can be crushed under dark conditions and then continue to use. Effective from the date of production
