Properties and Characteristics
Cyclodextrin (CDs) is a kind of cylco-Oligosaccaride. It is also the most steady and popular molecule microcapsule materials in recent time, It is natural and made
from natural starch. The conformation of the glucose
units in the cyclodextrin places the hydrophilic
hydroxyl groups at the top and bottom of the three dimensional ring and the
hydrophobic glycosidic groups on the interior.So the outer side of bucket keeps strong hydrophile characteristics, the inner side of bucket keeps
hydrophobic characteristics. Just because of the unique bucket’s hydrophilic
characteristics of outter side and hydrophobe charaacteristics of
inner side, it can entrap many kinds of guest moleculesin their internal, particularly to entrap oil form substance and form inclusion
complexes. If the guest substance
included by cyclodextrin to form inclusion complexes,
the stability and solubility increase obviously , and volatility reduced a lot. Depending
on it’s unique characteristc, CD is widely applied in
the fields of pharmaceuticals industry, food industry, cosmetics industry and household chemicals,
light industry,agricultures etc.
