Abstract

The invention relates to derivatives of cyclodextrins, their preparation and their use for incorporating hydrophobic molecules into organized surfactant systems. These derivatives of cyclodextrins are in accordance with the formula: ##STR1## in which R.sup.1 represents a group protecting an amine function, the R.sup.2, which can be the same or different, represent OH or NH--CH.sub.2 m--NHR.sup.1,m being an integer from 2 to 18 and n is equal to 5, 6 or 7.
