Esterquats, their intermediates, a process to make the esterquats, and their use as a fabric softener wherein said esterquats are of the formula: R4[R5R6N+Z]n X-, wherein Z is covalently bonded to the nitrogen atom and selected from the group of formulae (I)-(IV), and isomers thereof, wherein R¿1? and R2 are independently selected from linear or branched, saturated or unsaturated C6-22 hydrocarbyl, R3 is nothing or C1-20 hydrocarbyl, R4 is C1-6 alkyl or independent Z, R5 is H, C1-6 alkyl, independent Z, or the residue of the quaternizing agent, such as C1-30 alkyl or alkenyl, preferably, C1-7 alkyl or alkenyl, R6 is C1-6 alkyl or independent Z, and X?-¿ is an ion selected from Cl?-, Br-, l-, F-, CH¿3SO4-, C2H5SO4-, H2PO4-, HPO42-, PO43-, H2PO3-, HPO32-, H2PO2-, HPO22-, nitrate-, formate-, acetate-, propionate-, tartrate- and benzoate-, wherein the total charge of the anions equals the total charge of the cations and said process concerns the reaction of an unsaturated epoxide with an amine or a protonated amine, esterification of the formed intermediate, and optional quaternization.
