Claim: 1. Polysiloxanes of formula 1 MaDbDAcDBdDceTfQg  (formula 1) where M=[R2R12SiO1/2] D=[R12SiO2/2] DA=[R1Si(R7NHR3)O2/2] DB=[R1SiR4O2/2] DC=[R1SiR5O2/2] T=[R1SiO3/2] Q=[SiO4/2] in which R1 in each occurrence independently represents identical or different linear or branched, saturated or unsaturated hydrocarbon radicals having 1 to 30 carbon atoms or else aromatic hydrocarbon radicals having 6 to 30 carbon atoms, R2 in each occurrence independently represents R1, an alkoxy radical or a hydroxyl group, R3 in each occurrence independently represents hydrogen or a hydrocarbon radical substituted with nitrogen atoms, R4 in each occurrence independently represents identical or different linear or branched, saturated or olefinically unsaturated hydrocarbon radicals having 8 to 30 carbon atoms, for example decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, R5 in each occurrence independently represents identical or different linear or branched, saturated or unsaturated polar hydroxyl-substituted amide radicals having 1 to 30 carbon atoms and/or hydroxyl-substituted carbamate radicals having 1 to 30 carbon atoms and/or ethoxylated amine radicals having 1 to 30 carbon atoms and/or guanidine radicals or alkylenylguanidine radicals having 1 to 30 carbon atoms, R7 in each occurrence independently represents identical or different linear or branched, saturated or unsaturated, divalent hydrocarbon groups having 1 to 20 carbon atoms, a=2 to 20, b=10 to 5000, c=1 to 500, d=0 to 500, e=0 to 500, f=0 to 20, g=0 to 20, or their ionic adducts with protic reactants H+A−, with the proviso that at least 50% and preferably at least 70% of the R2 radicals are ═R1 and that at least one of the indices d and e≠0 and that in the case of d=0 e shall be ≠0 and in the case of e=0 d shall be ≠0.
Claim: 2. Polysiloxanes according to claim 1 with R5 a substituent selected from the group of substituents of formulae 1a to 1h [chemical expression included] where R6 is hydrogen, a hydrocarbon radical, an acyl radical, a carboxylate radical or a carbamate or carbonate radical.
Claim: 3. Polysiloxanes according to claim 1 with c, e in formula 1>0 and c>0.5*e.
Claim: 4. Polysiloxanes according to claim 1, characterized in that anions A− are identical or different counter-ions to the positive charges on the protonated nitrogen-containing groups, selected from organic or inorganic anions of the acids H+A− and also derivatives thereof.
Claim: 5. Polysiloxanes according to claim 2 with c, e in formula 1>0 and c>0.5*e and characterized in that anions A− are identical or different counter-ions to the positive charges on the protonated nitrogen-containing groups, selected from organic or inorganic anions of the acids H+A− and also derivatives thereof.
Claim: 6. Compositions comprising polysiloxanes according to claim 1.
Claim: 7. Compositions comprising polysiloxanes according to claim 6 and further formulation and processing auxiliaries such as for example aliphatic and aromatic, protic and aprotic solvents, cosurfactants, betaines, emulsifiers, fatty alcohol alkoxylates, mono-, di- and triglycerides, oils of synthetic and natural origin.
Claim: 8. A method of cleaning or reconditioning textiles and fabrics which comprises of applying an effective amount of the composition of claim 6.
Claim: 9. A process for preparing siloxanes according to claim 1, characterized in that different functional silanes are reacted in a condensation process with terminally hydroxyl-functional polydimethylsiloxanes to form multifunctional endblocked polysiloxanes, wherein aminoalkyldialkoxysilanes are functionalized at the amino group in a first step and cocondensed in a second step with hydroxyl-functional polydimethylsiloxanes in the presence of reagents releasing trimethylsilyl groups.
Claim: 10. The process according to claim 9, characterized in that trimethylsilyl groups endblock the silicone chain selectively without silating the amino groups or hydroxyl groups of the lateral organic modifications.
Claim: 11. The process according to claim 9, characterized in that a) terminally hydroxyl-functional linear or branched polysiloxanes and their mixtures with dimethyldialkoxysilanes or methyltrialkoxysilanes or tetraethoxysilane, b) hexamethyldisilazane, or disilazanes which are substituted with different carbon radicals, and c) 3-aminopropylmethyldialkoxysilanes, N-(2-amino-ethyl)-3-aminopropylmethyldialkoxysilanes or further functional dialkoxysilanes comprising linear or branched, saturated or unsaturated hydrocarbon radicals substituted with hydroxyl-substituted amides and/or hydroxyl-substituted carbamate structures and/or ethoxylated amines and/or guanidine or alkylenylguanidine structures, or selected from the group of substances of formulae 2a-i [chemical expression included] where R1 and R4 are each as defined for formula 1, R8 is a hydrogen atom, a methyl group or a carboxyl group and R9 is an alkyl or acyl radical, are reacted with one another.
Claim: 12. The process according to claim 10, characterized in that a) terminally hydroxyl-functional linear or branched polysiloxanes and their mixtures with dimethyldialkoxysilanes or methyltrialkoxysilanes or tetraethoxysilane, b) hexamethyldisilazane, or disilazanes which are substituted with different carbon radicals, and c) 3-aminopropylmethyldialkoxysilanes, N-(2-amino-ethyl)-3-aminopropylmethyldialkoxysilanes or further functional dialkoxysilanes comprising linear or branched, saturated or unsaturated hydrocarbon radicals substituted with hydroxyl-substituted amides and/or hydroxyl-substituted carbamate structures and/or ethoxylated amines and/or guanidine or alkylenylguanidine structures, or selected from the group of substances of formulae 2a-i [chemical expression included] where R1 and R4 are each as defined for formula 1, R8 is a hydrogen atom, a methyl group or a carboxyl group and R9 is an alkyl or acyl radical, are reacted with one another.
