Claim:
A polysiloxane of the general formula (I) where m is an integer from 5-200, n is an integer from 0-25, k is an integer from 1-25, R 1 is an aliphatic C 1 to C 30 radical or a phenyl radical, R 2 is an aliphatic C 9 to C 30 radical and/or a polyether radical of the general formula (CH 2 ) 3 O(C 2 H 4 O) x (C 3 H 6 O) y Q, where x and y may be the same or different and are each an integer between 0 and 50 and Q is hydrogen or an alkyl radical of 1 to 4 carbon atoms, R 3 is an epoxidic radical, E is an MZ radical, R 3 or R 2 , each molecule containing at least one epoxidic radical and one MZ radical, the epoxidic radical being selected from the group consisting of M being selected from the group consisting of Z being selected from the group consisting of where the quaternary nitrogen atom of the Z radical is attached to the M radical via the carbon atom adjacent to the C—OH group in the M radical, R 4 , R 5 and R 6 may be the same or different and may denote H, C 1 to C 22 alkyl, C 1 to C 22 alkenyl, which alkyl or alkylene radicals may contain hydroxyl groups, R 8 and R 9 may be the same or different and each has the same meaning as R 4 , R 5 and R 6 or are fluorine-, chlorine- or bromine-substituted C 1 to C 10 alkyl radicals, R 10 is an —O— or an NR 11 radical where R 11 ═H, C 1 to C 4 alkyl or C 1 to C 4 hydroxyalkyl, o is an integer from 1 to 4, A ⊖ is an organic or inorganic anion derived from a customary physiologically tolerable acid HX, where the epoxidic radical is selected from ether epoxies, where the M component of the MZ radical is selected from primary/secondary straight chain alcohols, and where the Z component of the MZ radical is selected from guaternary ammoniums.
