Abstract
The invention relates to the use of mono-3,6-anhydrocyclodextrins for solubilizing a hydrophobic compound and for controlling the purity of an enantiomer. The mono-3,6-anhydrocyclodextrin complies with the following formula: ##STR1## in which n is equal to 5, 6 or 7. Preferably n is equal to 6. The hydrophobic compound can be a steroid such as prednisolone.
