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.

A compound of general formula (I)
- wherein Rn and Rm independently represent a C3-C27 alkyl group,
- R1 to R6, which may be the same or different at each occurrence, represent hydrogen or a C1-C8 alkyl group or wherein a pair of substituents selected from R1, R2 and R3 in formula (I) or from R4, R5 and R6 in formula (I), optionally form a divalent hydrocarbon radical with 2 to 6 carbon atoms thereby forming a ring structure with the nitrogen atom to which they are attached,
- wherein at least one of R1 to R6 is a methyl group, and
- X1 and X2, which are the same or different at each occurrence, represent a linear or branched divalent hydrocarbon radical with 1 to 24 carbon atoms which can be optionally substituted and/or interrupted by one or more heteroatoms or heteroatom containing groups.
