Science
Why Cyclodextrins?
Cyclodextrins are cyclic oligosaccharides with a hydrophilic outer surface and a hydrophobic internal cavity — a unique amphiphilic structure that makes them versatile excipients and powerful research tools across multiple disciplines.
Inclusion Complex Formation
Cyclodextrins form host-guest inclusion complexes via hydrophobic interactions, encapsulating guest molecules within their toroidal cavity — the mechanistic foundation of virtually all CD applications in pharmaceutical and analytical science.
Solubility Enhancement
Poorly water-soluble compounds (BCS Class II/IV) can achieve 10–1000× solubility increases when formulated as CD inclusion complexes, a critical lever for bioavailability improvement in early-stage drug development.
Stabilization & Sensory Masking
CDs protect sensitive molecules from oxidation, hydrolysis, and photodegradation. They also mask bitter, astringent, or irritating sensory properties, enabling better-tolerated oral and topical formulations.
