Compositions obtained by reacting optionally quaternized aminoalkylaminoalkyl-trialkoxy-silanes with open-chain siloxanes and optionally cyclic siloxanes, then quaternizing any non-quaternary nitrogen atoms and optionally acidifying to below pH 7. Compositions obtained by reacting silane(s) of formula (R 1>O) 3Si-Z (Ia) with open-chain siloxane(s) of formula Y 3SiO-[Si(R)(X)O] a-[Si(R) 2O] b-[Si(R)(D)O] l-SiY 3(IIa) and optionally cyclic siloxane(s) of formula -[Si(R) 2O] z-(IIb), optionally followed by acidification to a pH of less than 7. z : 3-8, preferably 3 or 4; a : 0-500; b : 0-2000; (a+b) : 1-2000; l : 0 to 0.1 x b; the total number of -Si(R)(X)O- and -Si(R) 2O- units in (IIa) and (IIb) : 10-1000 times the number of Y 3SiO- units in (IIa); D : a residue of formula (1); Z : a group of formula -R 2>-[L-(CH 2) c] d-N(R 4>) 2(III) or -R 2>-[L-(CH 2) c] d-N +>(R 5>) 3(IV); R 4>, R 5>H or 1-18C alkyl; c : 2-6; d : 0, 1 or 2; L : -NR 4>- or -N +>(R 5>) 2-; R 2>2-6C alkylene; R : 1-4C alkyl, preferably methyl; X : a group of formula -R 2>-(OCHR 6>-CHR 7>) e-OR 4>(V); e : 2-25; R 6>, R 7>H or methyl, with the proviso that one of the groups is H and the other is H or methyl in each group (V); Y : R, Z or a group of formula -R 2>-CHOR 1>)-R (VI), R2-COOH (VII), -R 2>-O-CH 2-B (VIII) or -R 2>-OCH 2CH(OH)-[CH 2-N +>(R 5>) 2] t-(CH 2) k-N +>(R 5>) 3(IX); B : the monovalent cyclic residue derived from ethylene oxide, or a group of formula -CH 2CH 2OH or -CH(OH)CH 3; t : 0 or 1; k : 1 if t is 0, or 2-6 if t is 1 [Image] A quaternization reaction is carried out after the main reaction if neither (I) nor (II) contains a quaternary nitrogen atom, using counter ions selected from chloride, alkyl sulfate, alkylsulfonate, carboxylate, benzenesulfonate or toluenesulfonate. An independent claim is also included for aqueous dispersions containing these compositions.
