The Science

What are cyclodextrins?

Cyclodextrins are ring-shaped sugar molecules made from starch. Each ring has a water-loving outer surface and a water-repelling inner cavity, and that cavity can capture another molecule to form a stable inclusion complex. That simple mechanism lets cyclodextrins improve the solubility, stability, and delivery of compounds that are otherwise difficult to formulate.

αAlpha-cyclodextrin
6 glucose units~5.7 Å cavity

The smallest cavity, suited to small guest molecules.

βBeta-cyclodextrin
7 glucose units~7.8 Å cavity

The most widely used, a versatile, mid-sized cavity.

γGamma-cyclodextrin
8 glucose units~9.5 Å cavity

The largest cavity, fits bigger or bulkier guests.

Improve solubility

Carry poorly water-soluble actives into solution, improving aqueous solubility and dissolution.

Protect & stabilize

Shield sensitive ingredients from light, heat, and oxidation, and mask bitter taste or odor.

Control delivery

Turn volatile liquids into stable powders and release actives where and when they are needed.
