Abstract:
The invention relates to a novel methylated cyclodextrin and to a novel method used for the production thereof. The invention also relates to the use of said methylated cyclodextrin for the solubilisation of lipophilic compounds, or carriers of at least one lipophilic group. The invention further relates to a composition comprising said methylated cyclodextrin, particularly a pharmaceutical composition.

Claim (Index 8):
A process for preparing a methyl cyclodextrin having a degree of molar substitution (MS) of between 0.05 and 1.50, comprising the steps of:\n (a) etherification of a cyclodextrin with a methylation reagent, said etherification being carried out in basic medium, at a temperature of between 100 and 200\u00b0 C. and at a pressure between 1 and 10 bar; (b) decreasing ionic species of the methyl cyclodextrin obtained in step (a), such that the conductivity of said methyl cyclodextrin, when it is in the form of a solution of distilled water at a concentration of 10%, is reduced to a value of less than or equal to 50 \u03bcS/cm; (c) drying the methyl cyclodextrin obtained in step (b); and (d) recovering the methyl cyclodextrin obtained in step (c).
