Provided are polyglyceryl compositions comprising one or more polyglycerylcompoundshaving: (a) a node structure comprising at least three contiguous glycerylremnant units； (b) oneor more cationic groups each linked to the node structure by an independentlyselected linkinggroup； and (c) one or more hydrophobic moieties each independently (i) linkedto the nodestructure by a linking group, or (ii) constituting a portion of one of the oneor more cationicgroups, wherein the composition has an average degree of polymerizationdetermined byhydroxyl value testing (DP OH) of from about 3 to about 20. Also provided arepolyglycerylcompounds which may compose such compositions, and uses of the polyglycerylcompositionsand compounds.
