<p>The invention concerns compounds of formula (I) prepared by quaternizing a compound (II) with at least a compound R3 - X- wherein: R1 = H or -CH¿3; R?2 = -CH¿3?; -C2H5; -C2H7 or - C4H9; and the compound (I) is optionally quaternized on one of the nitrogen atoms, symbolised by the fact that the R3's, X?-¿- and + associated with said nitrogen are between square brackets; when compound (I) is quaternized on one single nitrogen, R?3 and X-¿ represent the following: (1) R3 = -CH¿3? or -CH2C6H5; and X?- = Cl-¿ or CH¿3OSO3?-; or (2) R3 = C1-C12 alkyl; and X?- = Br- or I-¿; when compound (I) is quaternized on two nitrogen atoms, both X-'s can be identical or different and both R3's can be identical, in which case: R3 = C5-C12 alkyl; and X- = CH3OSO3?-, Br- or I-¿; or different, in which case: (4) one of the R3's = -CH¿3? or -CH2C6H5; and X?- = Cl-¿ or CH¿3OSO3?-; and the other R3 = a C¿5?-C12 alkyl group; and X?- = Br- or I-¿.</p> |
