Definitions
- the invention relates to polymeric dyes which are obtained by condensation of cationic biopolymers with dyes, a process for their preparation, agents for dyeing fibers which contain these dyes, processes for dyeing fibers using the abovementioned polymeric dyes and their use for dyeing fibers.
- direct dyes or oxidation dyes are usually used, the latter being composed of a developer and a coupler component and forming directly on the hair under the action of oxidizing agents or atmospheric oxygen .
- a further disadvantage of the known hair coloring or tinting agents is that the products penetrate into the keratin fibers in any case and thus cause damage to the hair structure, even if it is usually minor. Since the agents do not act selectively on keratin fibers, the treated scalp is usually also colored, which is also considered undesirable by the consumer.
- the object of the present invention was to provide new agents for the temporary dyeing of keratin fibers which are free from the disadvantages described.
- the invention relates to polymeric dyes which are obtained by condensing cationic biopolymers with dyes which have a leaving group.
- suitable representatives are cationic biopolymers chitosans and dyes which have a halogen function as a leaving group.
- the invention further relates to a process for producing polymeric dyes, in which cationic biopolymers, preferably chitosans, are condensed with dyes which have a leaving group, preferably a halogen function.
- Chitosans which also belong to the group of hydrocolloids, are among the best known and, in the sense of the invention, most preferred cationic biopolymers. From a chemical point of view, these are partially deacetylated chitins of different molecular weights, which contain the - idealized - monomer unit (I): CH 2 OH HO NH 2
- chitosans are cationic biopolymers under physiological conditions.
- the positively charged chitosans can interact with oppositely charged surfaces and are therefore used in cosmetic hair and body care products, but also as thickeners in amphoterics / cationic surfactant mixture used.
- Overviews on this topic are, for example, by B. Gesslein et al. in HAPPI 7J- ⁇ 57 (1990), O.Skaugrud in Drug Cosm. Ind. 148, 24 (1991) and E. Onoyen et al. appeared in Seifen- ⁇ le-Fette-Wwachs 117, 633 (1991).
- the chitosans are produced from chitin, preferably the shell remains of crustaceans, which are available in large quantities as cheap raw materials.
- the chitin is usually first deproteinized by adding bases, demineralized by adding mineral acids and finally deacetylated by adding strong bases, it being possible for the molecular weights to be distributed over a broad spectrum.
- Corresponding processes for the production of - microcrystalline - chitosan are described, for example, in WO 91/05808 (Firextra Oy) and EP-Bl 0382150 (Hoechst).
- chitosan derivatives such as, for example, carboxymethylchitosan or hydroxypropylchitosan, can also be used as starting materials.
- the cationic biopolymers obtainable by the process described above have a degree of deacetylation of 30 to 100 and preferably 60 to 98%. As a result of their low ash content, they also have a particularly advantageous viscosity.
- cationic biopolymers should also be understood to include related feedstocks such as gelatin, collagens and collagen breakdown products. Dyes
- the invention is based on the surprising finding that basically all dyes, i.e. chemical compounds which absorb in the visible light range and thus have a chromophore, can be used as reaction partners for the cationic biopolymers, provided that there is a suitable leaving group in the molecule which primarily provides an addition or condensation with a nitrogen ⁇ group of the biopolymer makes possible. Accordingly, the prerequisite for the cationic biopolymer is that a sufficient proportion of the nitrogen groups in the macromolecule is not substituted.
- both the nitroaaniline dyes known for hair dyeing and the azo and anthraquinone dyes used predominantly in the field of textile dyeing are suitable as dyes.
- the dyes which are preferably used in the sense of the invention and have a suitable leaving group are nitroaniline compounds which are substituted on the aromatic ring by at least one nitro group and one halogen group.
- Nitroaniline compounds are preferably used as dyes,
- amino group is substituted with at least one alkyl, aminoalkyl, hydroxyalkyl, dihydroxyalkyl and / or alkoxy radical having 1 to 15 carbon atoms, and / or
- Typical nitroaniline compounds which are suitable as starting materials for the purposes of the invention are, for example, 2-chloro-4-nitroaniline, 3-fluoro-4-nitroaniline, 2-nitro-4-bromoaniline, 4-chloro-3-nitro l- [N-2-hydroxyethylamino] benzene, 4-fluoro-2-nitro-l- [N, N-bis-2-hydroxyethylamino] benzene, 4-fluoro-3-nitroaniline and 2-chloro-6- methyl-3-nitroaniline.
- Further substitution munitions for suitable aniline compounds can be found in "The che istry of synthetic dyes, Vol.V.”, (ed. K. Venkatara- man), Academic Press, New York, London, 1971, pp. 508-518.
- the reaction of the cationic biopolymers with the dyes is a simple condensation between a nitrogen function of the biopolymer and the leaving group of the dye. If the leaving group represents, for example, chloride, the reaction between the two components cleaved hydrogen chloride, which can be bound as an adduct via a basic nitrogen group in the molecule.
- the cationic biopolymers and the dyes are usually used in a stoichiometric ratio of about 1: 1, the molar amount of the dye being calculated based on the molar mass of the nitrogen groups in the biopolymer.
- the reaction is preferably carried out in the presence of a basic compound such as potassium carbonate or sodium carbonate in an organic solvent such as ethanol under reflux over a period of 1 to 12 and typically 5 to 8 hours. It is then recommended to separate the condensation product from the mother liquor, wash it carefully and dry it. The yield of usually crystalline addition products is practically quantitative.
- the invention furthermore relates to compositions for the permanent dyeing of fibers, preferably keratin fibers, which contain the abovementioned polymeric dyes.
- the polymeric dyes can be incorporated, for example, in a suitable water-containing carrier.
- a suitable water-containing carrier for the purpose of hair coloring, such carriers are, for example, creams, emulsions, gels or also surfactant-containing foaming solutions, for example shampoos, foam aerosols or other preparations which are suitable for use on the hair.
- surfactants are, for example, creams, emulsions, gels or also surfactant-containing foaming solutions, for example shampoos, foam aerosols or other preparations which are suitable for use on the hair.
- the colorants according to the invention can contain all active ingredients, additives and auxiliaries known in such preparations.
- the colorants contain at least one surfactant, both anionic and zwitterionic, ampholytic, nonionic and cationic surfactants being suitable in principle.

If the nonionic surfactants contain polyglycol ether chains, they can have a conventional, but preferably a narrow, homolog distribution.
- cationic surfactants are quaternary ammonium compounds and ester quats, in particular quaternized fatty acid trialkanolamine ester salts.
- cationic silicone oils such as, for example, the commercially available products Q2-7224 (manufacturer: Dow Corning; a stabilized trimethylsilylamodimethicone), Dow Corning 929 emulsion (containing a hydroxylamino-modified silicone, which is also used as an amodi methicone), SM-2059 (manufacturer: General Electric), SLM-55067 (manufacturer: Wacker) and Abil (R ) -Quat 3270 and 3272 (manufacturer: Th. Goldschmidt; diquaternary polydimethylsiloxane, Quaternium-80).
- alkylamidoamines in particular fatty acid amidoamines such as the stearyl amidopropyldimethylamine available under the name Tego Amid (R) S 18, are notable in particular for their good biodegradability.
- amphoteric or zwitter onic surfactants are alkyl betaines, alkyl amido betaines, aminopropionates, amino glycinates, imidazolinium betaines and sulfobetaines.
- the surfactants mentioned are exclusively known compounds. With regard to the structure and manufacture of these substances, reference is made to relevant reviews, for example J.Falbe (ed.), "Surfactants in Consumer Products", Springer Verlag, Berlin, 1987, pp. 54-124 or J.Falbe (ed.) , “Catalysts, surfactants and mineral oil additives", Thieme Verlag, Stuttgart, 1978, pp. 123-217.
- the agents according to the invention can contain emulsifiers, superfatting agents, thickeners, biogenic agents, film formers, preservatives, colorants and fragrances as further auxiliaries and additives.
- W / 0 and 0 / W emulsifiers such as, for example, hardened and ethoxylated castor oil, polyglycerol fatty acid esters or polyglycerol poly ricinoleates or polyglycerol poly 12-hydroxystearate come into question as emulsifiers.
- Substances such as, for example, polyethoxylated lanolin derivatives, lecithin derivatives, polyol fatty acid esters, monoglycerides and fatty acid alkanolamides can be used as superfatting agents, the latter simultaneously serving as foam stabilizers.
- Suitable thickening agents are, for example, polysaccharides, in particular xanthan gum, guar guar, agar agar, alginates and tyloses, carboxymethyl cellulose and hydroxyethyl cellulose, furthermore higher molecular weight polyethylene glycol monoesters and diesters of fatty acids, polyacrylates, polyvinyl alcohol and polyvinyl pyrrolidone, surfactants such as, for example, fatty alcohol ethoxylates with a narrow homolog distribution or alkyl oligoglucosides, and electrolytes such as sodium chloride and ammonium chloride.
