Abstract: The present invention concerns new cationic quaternary ammonium compounds which exhibit excellent adsorption properties on negatively charged surfaces. These ones can notably be obtained firstly by reacting an internal ketone with a twin-tail amine under reductive amination conditions to obtain a twin tail triamine, then subjecting the twin tail triamine to a quaternization reaction. They can also obtained be obtained by the quaternization reaction of a certain diamine.
