Preparation and characterization of soluble branched ionic β-cyclodextrins and their inclusion complexes with triclosan

•Branched anionic and cationic β-cyclodextrins were obtained from parent β-CDs.•Water solubility of ionic branched β-cyclodextrins (bβCD) was higher than neutral ones.•No cytotoxic effects were observed for ionic bβCDs.•Ionic bβCDs form complexes with triclosan but show a complexation limit.•Complexes of triclosan with anionic bβCDs showed higher stability constant than with cationic bβCDs.
