Patent ID: 7825207

Claim:
A polysiloxane containing guanidino groups and of the general formula (I) in which the radicals R 1 are identical or different and are an optionally branched hydrocarbon radical which optionally contains double bonds and has 1 to 30 carbon atoms or phenyl radicals or —OR 11 or —OH, R 2 can in part have the meaning of the radicals R 1 and the other radicals R 2 , independently of one another, are radicals of the formulae (Ia, Ib or Ic) R 2 =-M-G (Ia) R 2 =-M-Q + A − (Ib) R 2 =-(M) x -S (Ic) with the proviso that, in the average molecule, at least one radical R 2 is a radical of the formula -M-G (Ia), in which G is a guanidino group with the general formula (Ia 1 , Ia 2 ) and/or salts or hydrates thereof, in which R 3 a) independently of the others, is hydrogen or an optionally branched hydrocarbon radical optionally comprising double bonds, R 3′ is R 3 or an alkylene group which is joined to M via carbon atoms or heteroatoms and in so doing forms a 5- to 8-membered ring, and M is a divalent or polyvalent hydrocarbon radical having at least 4 carbon atoms which has one hydroxyl group and which can be interrupted by one or more oxygen atoms or nitrogen atoms or quaternary ammonium groups or ester or amide functions, Q + is a radical of the formula (Id) R 4 , R 5 are alkyl radicals having 1 to 4 carbon atoms, R 6 is R 7 is a monovalent hydrocarbon radical having 1 to 22 carbon atoms, y is 0 to 6 z is 0 or 1, A − is an inorganic or organic anion which originates from a physiologically compatible acid HA, S is H, or a polyalkylene oxide polyether of the general formula C m H 2m O(C 2 H 4 O) n (C 3 H 6 O) o R 8 in which m is 1 to 6, n,o independently of one another are 0 to 100 and the polyether has a molecular weight between 100 and 6000 g/mol and R 8 is H or an optionally branched aromatic or alicyclic hydrocarbon radical optionally containing double bonds and having 2 to 30 carbon atoms, or a UV-absorbing group, R 11 is an aliphatic or aromatic hydrocarbon radicals having 1 to 30 carbon atoms which are optionally branched or H, x is 0 or 1 and a independently of the others has a value of from 4 to 1000, and b has a value from 0 to 10.
