Definitions
- a method of dyeing keratin fibers comprising using a dye containing aminosilicone and pigment and a shampoo containing aminosilicone
- the subject matter of the present application is a process for coloring keratinic fibers, in particular human hair, which comprises using a coloring agent (F) and using a shampoo (S).
- the colorant (F) contains at least one amino-functionalized silicone polymer (f1) and at least one pigment (f2).
- the shampoo (S) contains at least one amino-functionalized silicone polymer (s1).
- a second subject matter of the present application is a multi-component packaging unit (kit-of-parts) which contains the colorant (F) described above and the shampoo (S) in separately packaged containers.
- a third subject of this application is the use of the shampoo (S) described above to improve color retention on keratinic fibers which were colored by using a colorant (F) containing at least one amino-functionalized silicone polymer (f1) and at least one pigment (f2).
- Oxidation colorants are usually used for permanent, intensive colorations with good fastness properties and good gray coverage. Such colorants contain oxidation dye precursors, so-called developer components and coupler components, which form the actual dyes among themselves under the influence of oxidizing agents such as hydrogen peroxide. Oxidation coloring agents are characterized by very long-lasting coloring results.
- color pigments are known for short-term color changes on the hair and/or the skin.
- Pigments or color pigments are generally insoluble, understood coloring substances. These are present in undissolved form in the form of small particles in the coloring formulation and are only deposited from the outside on the hair fibers and/or the surface of the skin. Therefore, they can usually be removed without leaving any residue with a few washes with detergents containing surfactants.
- Various products of this type are available on the market under the name of hair mascara.
- the fastness to washing should be outstanding, but the use of the oxidation dye precursors otherwise usually used for this purpose should be avoided.
- a technology was sought that would make it possible to apply the coloring compounds (particularly pigments) known from the prior art to the hair in an extremely durable manner to fix. If the agents are used in a dyeing process, intensive dyeing results with good fastness properties and good color retention should be achieved.
- keratinic fibers that have been colored in a first step by using a coloring agent with aminosilicone and pigment have improved fastness to washing, especially when a shampoo that also contains an aminosilicone is used in a subsequent step.
- a first object of the present invention is a method for dyeing keratin fibers, in particular human hair, comprising the
- keratin fibers in particular hair
- the wash fastness properties of the dyeings obtained in this way could be further improved if, after dyeing, a shampoo (S) which likewise contained an amino-functionalized silicone polymer (s1) was applied to the keratin fibers at least once.
- a shampoo (S) which likewise contained an amino-functionalized silicone polymer (s1) was applied to the keratin fibers at least once.
- the post-dyeing application of the shampoo (S) strengthens the film of silicone and pigment formed in the dyeing process or closes gaps in the film due to the presence of the aminosilicone (s1) in the shampoo. In this way, the impairment or damage to the film that inevitably occurs as a result of contact with the surfactants present in a shampoo can be compensated for.
- Keratin fibers are to be understood as meaning wool, fur and feathers and, in particular, human hair. Very particularly preferably, keratin fibers are understood as meaning human hair.

- the maximum molecular weight of the silicone polymer depends on the degree of polymerisation (number of polymerised monomers) and the batch size and is also determined by the polymerisation method. For the purposes of the present invention, it is preferred if the maximum molecular weight of the silicone polymer is no more than 10 7 g/mol, preferably no more than 10 6 g/mol and particularly preferably no more than 10 5 g/mol.
