Definitions

  • the invention relates to organic sulfinic acid derivatives which are distinguished as reducing agents and are used in the decoloration of colored substrates such as paper, textiles and keratin-containing fibers, for example human hair.
  • a method for decoloration of colored substrates, as well as a decolorizing agent is the subject of the invention.
  • the dye In dyeing, the dye is transferred to the substrate by adsorption to the surface, by diffusion, by formation on and / or in the substrate, or by chemical bonding.
  • natural dyes such as purple or carmine were used.
  • oxidation dyes are generally suitable for dyeing, for example, paper, textiles or keratin fibers.
  • Oxidative dyes are formed by oxidative coupling of one or more developer components with each other or with one or more coupler components. Coupler and developer components are also referred to as oxidation dye precursors. The oxidative coupling preferably takes place during the dyeing process, so that the dye precursors into the substrate can diffuse and the dye forms in the substrate. The size of the resulting dye molecule makes it difficult to wash out of the substrate.
  • the developer components are usually primary aromatic amines having a further free or substituted hydroxy or amino group in para or ortho position, diaminopyridine derivatives, heterocyclic hydrazones, 4-aminopyrazolone derivatives and 2,4,5,6-tetraaminopyrimidine and derivatives thereof used.
  • m-phenylenediamine derivatives naphthols, resorcinol and resorcinol derivatives, pyrazolones, m-aminophenols and substituted pyridine derivatives are generally used.
  • Suitable coupler substances are in particular ⁇ -naphthol, 1, 5, 2,7- and 1, 7-dihydroxynaphthalene, 5-amino-2-methylphenol, m-aminophenol, resorcinol, resorcinol monomethyl ether, m-phenylenediamine, 2,4-diaminophenoxyethanol , 2-amino-4- (2-hydroxyethylamino) -anisole (Lehmann's Blue), 1-phenyl-3-methyl-pyrazol-5-one, 2,4-dichloro-3-aminophenol, 1,3-bis - (2,4-diaminophenoxy) -propane, 2-chlororesorcinol, 4-chlororesorcinol, 2-chloro-6-methyl-3-aminophenol, 2-methylresorcinol, 5-methylresorcinol, 3-amino-6-methoxy-2 -methylamino-pyridine and 3,5-diamino-2,6-dime
  • Direct-acting dyes are generally understood to be dyes which are already preformed before the beginning of dyeing and are applied to the substrate.
  • Important representatives of this class of dyes are, for example, triphenylmethane dyes, azo dyes, anthraquinone dyes or nitrobenzene dyes, which may each carry cationic or anionic groups.
  • an important technical field is the removal of dyes. This generally refers to the removal of dyeings or prints by washing, chemical modification or destruction of the dye. The oxidative or reductive discoloration of dyed materials finds particular application in the decolorization of textiles or hair.
  • Oxidative discoloration usually leads to good results.
  • the structure of the substrate can be chemically altered by the strong oxidizing action of the decolorizing oxidizing agent. This is accompanied by an undesirable physical change of the substrate. For example, textiles or hair can become brittle or even break, especially if they are discolored several times. The visual impression, the feel as well as the durability of the substrate are negatively influenced.
  • reductive decolorizing agents scarcely discolour the natural hair color but have a reductive effect only on the dyes applied by dyeing. There is thus hardly any whitening of the hair.
  • the reductive decolorants require an improvement in decolorization performance.
  • reductive sulfur compounds for decolorization.
  • dithionites or derivatives of 1-hydroxymethylsulfinic acid or of 1-aminomethylsulfinic acid are suitable as reducing agents.
  • 1-hydroxyalkylsulfinic acids or 1-aminoalkylsulfinic acids which carry a carboxy group, a sulfonic acid group, an acyl group, an aminocarbonyl group or an alkoxycarbonyl group are suitable for decolorization of colored substrates.
  • Said derivatives have a comparable or better decolorization power as the 1-hydroxymethylsulfinic acid (vide supra), but do not cleave formaldehyde.
  • W0-A1 -02 / 30369 describes the discovery that with the sulfinic acid derivatives of WO-A1 -99 / 18067 keratin-containing fibers, such as, for example, hair, can be decolorized.
  • Further sulfinic acid derivatives which are suitable for decolorizing keratin-containing fibers can be found in the publications W0-A1 -03 / 026597 and WO-A1-03 / 41668.
  • the object of the present invention is to provide reductive decolorizing agents which decolorize the substrate permanently without darkening.
  • the substrate structure should be spared.
  • the reducing agents used in the decolorizing agents for a cosmetic use should be physiologically acceptable and toxicologically harmless.
  • the organic sulfinic acid derivatives according to the invention are outstandingly suitable for decolorizing colored substrates, such as paper, textiles or keratin fibers, in particular human hair, without darkening to a high degree after the decolorization process, as is the case with the use of the sulfinic acid derivatives of the prior art Technique is caused.

Abstract

L'invention concerne des dérivés d'acide sulfinique spécifiques de formule (I), dans laquelle M représente un atome d'hydrogène ou un équivalent d'un cation monovalent ou polyvalent; R est dérivé d'un peptide ou représente un radical correspondant aux formules (II) à (IV), (les substituants restants étant spécifiés dans la revendication 1), ceci permettant une décoloration permanente de substrats colorés, tout en évitant l'assombrissement des substrats décolorés. La structure du substrat est protégée lors du processus de décoloration.
