Abstract: New linear or branched polyamino- and/or polyammonium-polysiloxane copolymers are used in the production and/or treatment of dyed hair. The use of (b1) linear or branched polyamino- and/or polyammonium-polysiloxane copolymers with repeat units of formula -[Q-V]- (I) (in which the positive charges associated with ammonium groups are neutralized with organic or inorganic acid anions) or their acid addition salts and optionally (b2) amino- and/or ammonium-polysiloxane compounds in the production and/or treatment of dyed hair. Q : -NR-, -N +>R 2-, a saturated or unsaturated diamino-functional heterocycle of formula (Q1), (Q2) or (Q3), an aromatic diamino-functional heterocycle of formula (Q4), a trivalent group of formula -N= or -N(R) +>= or a tetravalent group of formula =N +>=, in which Q is not directly attached to a carbonyl carbon; R : H or a monovalent organic group; V : V 1>, V 2>or V 3>; V 2>a divalent, linear, cyclic or branched, saturated, unsaturated or aromatic hydrocarbon residue with up to 1000 C atoms (not including those in the polysiloxane group Z 2>defined below), optionally containing -O-, -CONR 2>-, -CO- and/or -CS- group(s), optionally substituted with hydroxyl group(s) and containing at least one group -Z 2>- of formula -Si(R 1>) 2O-[Si(R 1>) 2O] n1-Si(R 1>) 2-; R 2>H or a monovalent hydrocarbon group (various types as above) with up to 100 C atoms (optionally containing -O-, -NH-, -CO- and/or -CS- group(s), and optionally substituted with OH, optionally substituted heterocyclic groups (preferably with one or more N atoms), amino, (di)alkylamino, ammonium, polyether or polyether-ester residues); R 1>1-22C alkyl, 1-10C fluoroalkyl or 6-10C aryl; n1 : 20-1000; V 1>as for V 2>, optionally substituted with OH and optionally containing a group Z 1>of formula -Si(R 1>) 2O-[Si(R 1>) 2O] n2-Si(R 1>) 2-; n2 : 0-19; V 3>as for V 2>, but optionally containing -O-, -CONH-, -CONR 2>-, -CO-, -CS-, -Z 1>-, -Z 2>- and/or -Z 3>- group(s) and optionally substituted with OH; and Z 3>an organopolysiloxane unit with a valency of 3 or more; with the proviso that the polysiloxane compound contains at least one group V 1>, V 2>or V 3>and at least one group Z 1>, Z 2>or Z 3>, the tri- or tetra-valent groups Q either act as the branching point of the Q-V main chain with the other valencies carrying other branches based on -[Q-V]- units, or these groups are saturated with V 3>groups in a linear main chain with no branches. [Image] Independent claims are also included for the following: (1) a method (M1) for the production of a composition for the production and/or treatment of dyed hair by mixing (b1) and optionally (b2) with nitrogen-free polysiloxane compounds, silicone-free surfactants, coacervate phase formers and carrier substances; and (2) compositions as defined in M1, especially shampoos, hair rinse formulations, hair-care cures, formulations for dyeing or for the care and conditioning of dyed hair, and developers for permanent hair dyeing.
