Abstract
A cationic ester surfactant comprising at least one ester linkage and at least one cationically charged group, characterized in that said cationically charged group is an ammonium group substituted by at least one hydrodyalkyl group. Surfactant systems and detergent compositions containing the cationic surfactant which are suitable for use in laundry and dishwashing are provided, as are methods of use.
