Abstract

Sulphonated derivatives of cyclomalto-oligosaccharides, their preparation process and support for active substances containing said derivatives. These derivatives are in accordance with the following formula (I) ##STR1## in which n is an integer from 2 to 50 and R represents --SO.sub.3.sup.- Na.sup.+ or --OH, in which R can differ from one cycle to the other. They can be used for transporting injectable or ingestable medicaments.
