Natural Cyclodextrins
The most common cyclodextrins are alpha, beta, and gamma cyclodextrins having six (α), seven (β), or eight (γ) anhydroglucose units in the ring structure. Among them, beta Cyclodextrin is mostly common used.
Different sizes lead to different physicochemical characteristics for the respective molecules:

Chemically modified Cyclodextrins
Cyclodextrins can be modified by various procedures such as:
Substituting one or more hydrogen atoms in the primary and/or secondary hydroxyl groups (esters, ethers, glycosylcyclodextrin)
Substituting one or more primary and/or secondary hydroxyl groups
Chemically modified Cyclodextrins (CDM's) exhibit substantially increased aqueous solubility with concomitant retention of the inclusion complexing properties of the starting Cyclodextrin. They therefore appear to offer specific applications within various industries, such as foods, pharmaceuticals, personal care/cosmetics, diagnostics, etc. Hydroxyalkyl b Cyclodextrins such as Hydroxypropyl b Cyclodextrin are examples of those chemically modified Cyclodextrins.
