Science
Why Cyclodextrins?
Cyclodextrins are cyclic oligosaccharides with a hydrophilic outer surface and a hydrophobic internal cavity. This amphiphilic structure lets them act as solubilizers and research tools across pharmaceutical, food, and analytical work.
Inclusion Complex Formation
Cyclodextrins form host-guest inclusion complexes via hydrophobic interactions, encapsulating guest molecules within their toroidal cavity. This is the mechanism behind most CD applications in pharmaceutical and analytical work.
Solubility Enhancement
Poorly water-soluble compounds can show substantially improved aqueous solubility and dissolution when formulated as CD inclusion complexes, a useful approach in early-stage formulation research.
Stabilization & Sensory Masking
CDs protect sensitive molecules from oxidation, hydrolysis, and photodegradation. They also mask bitter, astringent, or off-odor sensory properties, supporting taste and odor masking in food and formulation research.
