PCT No. PCT/FR94/01502 Sec. 371 Date Dec. 9, 1996 Sec. 102(e) Date Dec. 9, 1996 PCT Filed Dec. 21, 1994 PCT Pub. No. WO95/17433 PCT Pub. Date Jun. 29, 1995The 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: IMAGE (I) 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.
