The present invention relates to polygalactomannans modified with amphipathic and amphiphilic with repeating units having an average D-mannosyl to D-galactosyl residue ratio of at least 5 to 1, and compositions containing them. Portions of the hydrogen atoms of the hydroxyl groups located on the mannosyl and galactosyl residues of galactomannan are replaced by amphiphilic and cationic substituents. |
