Definitions
- the present application relates to a method for coloring keratinic material, in particular human hair, which comprises the use of a coloring agent (a), the coloring agent containing at least one amino-functionalized silicone polymer and at least one coloring compound.
- a coloring agent containing at least one amino-functionalized silicone polymer and at least one coloring compound.
- the process is characterized by an action time of the agent on the keratin material of 15 seconds to 10 minutes and the subsequent rinsing of the dye under running water for a period of 15 seconds to 10 minutes.
- Oxidation dyes are usually used for permanent, intense dyeings with good fastness properties and good gray coverage. Such colorants contain oxidation dye precursors, so-called developer components and coupler components, which, under the influence of oxidizing agents such as hydrogen peroxide, form the actual dyes with one another. Oxidation dyes are characterized by very long-lasting coloring results.
- color pigments are generally understood to mean insoluble, coloring substances. These are present undissolved in the form of small particles in the coloring formulation and are only deposited on the outside of the hair fibers and / or the skin surface. Therefore, they can usually be removed without residue by a few washes with detergents containing surfactants. Various products of this type are available on the market under the name of hair mascara.
- oxidative coloring agents have so far been his only option.
- an unpleasant ammonia odor or amine odor can be found in oxidative hair coloring do not avoid completely.
- the hair damage still associated with the use of oxidative coloring agents also has an adverse effect on the user's hair.
- the search for alternative, high-performance dyeing processes remains a challenge.

- the colorant (a) here contains at least one amino-functionalized silicone polymer (a1) and at least one coloring compound (a2).
- the aminosilicones (a1) contained in the agent form a film from the keratin material in which the coloring compound (a2) is embedded.
- coloring compounds (a2) when used simultaneously with the amino silicone (a1), attach to the latter or form a common layer with it.
- This common layer formation of (a1) and (a2) leads to the fact that colorations with high color intensity can be obtained without the need for diffusion of the coloring compound into the hair fiber.

- a particularly preferred embodiment is therefore characterized in that the agent according to the invention contains an alkanolamine selected from 2-aminoethan-1-ol and / or 2-amino-2-methylpropan-1 -ol as alkalizing agent.
- amino acid in the context of the invention is an organic compound which in its structure contains at least one amino group which can be protonated and at least one —COOH or one —SOsH group.
- Preferred amino acids are aminocarboxylic acids, in particular ⁇ - (alpha) -amino carboxylic acids and w-aminocarboxylic acids, ⁇ -aminocarboxylic acids being particularly preferred.
- basic amino acids are to be understood as meaning those amino acids which have an isoelectric point p1 of greater than 7.0.
- Basic ⁇ -aminocarboxylic acids contain at least one asymmetric carbon atom.
- both possible enantiomers can be used equally as a specific compound or also mixtures thereof, in particular as racemates will.
- the basic amino acids are preferably selected from the group that is formed from arginine, lysine, ornithine and histidine, particularly preferably from arginine and lysine.
- an agent according to the invention is therefore characterized in that the alkalizing agent is a basic amino acid from the group arginine, lysine, ornithine and / or histidine.
- the agent can contain other alkalizing agents, in particular inorganic alkalizing agents.
- Inorganic alkalizing agents which can be used according to the invention are preferably selected from the group formed by sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium phosphate, potassium phosphate, sodium silicate, sodium metasilicate, potassium silicate, sodium carbonate and potassium carbonate.
- Very particularly preferred alkalizing agents are ammonia, 2-aminoethan-1-ol (monoethanolamine), 3-aminopropan-1-ol, 4-aminobutan-1 -ol, 5-aminopentan-1 -ol, 1-aminopropan-2-ol, 1-aminobutan-2-ol, 1-aminopentan-2-ol, 1-aminopentan-3-ol, 1-aminopentan-4-ol, 3-amino-2-methylpropan-1-ol, 1-amino-2- methylpropan-2-ol, 3-aminopropan-1, 2-diol, 2-amino-2-methylpropan-1, 3-diol, arginine, lysine, ornithine, histidine, sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium phosphate, potassium phosphate, Sodium silicate, sodium metasilicate, potassium silicate, sodium carbonate and potassium carbonate.
- a method according to the invention is characterized in that the colorant (a) has at least one alkalizing agent from the group consisting of ammonia, 2-aminoethan-1-ol (monoethanolamine), 3-aminopropan-1 -ol, 4- Aminobutan-1 -ol, 5-aminopentan-1-ol, 1-aminopropan-2-ol, 1-aminobutan-2-ol, 1-aminopentan-2-ol, 1-aminopentan-3-ol, 1-aminopentan 4-ol, 3-amino-2-methylpropan-1 -ol, 1-amino-2-methylpropan-2-ol, 3-aminopropan-1, 2-diol, 2-amino-2-methylpropan-1, Contains 3-diol, arginine, lysine, ornithine, histidine, sodium hydroxide, potassium hydroxide, calcium hydroxide, barium hydroxide, sodium
- step (2) of the method according to the invention the coloring agent (a) is allowed to act on the keratinic material for a period of 15 seconds to 10 minutes.
- a great advantage of the dyeing process according to the invention is that an intense color result can be achieved even in very short periods of time after short exposure times.
- the reason is to leave the colorant (a) on the keratin material only for comparatively short periods of time of 15 seconds to 10 minutes after its application.
- a further shortening of the exposure time increases the comfort of use without any loss of color intensity. For this reason, it is very particularly preferred to leave the coloring agent (a) on the keratin material for even shorter periods of time from 30 seconds to 5 minutes, particularly preferably from 30 seconds to 2 minutes.
- Running water is understood to mean running tap water that is taken from the open tap of a drinking water pipe. In a normal water pipe, the water pressure is 3 - 5 bar.
- precisely one cosmetic agent namely the coloring agent (a) is applied to the keratin material and rinsed out again under running water after the end of the exposure time.
- Another shampoo, conditioner or post-treatment agent is not used.
- the rinsing process in step (3) must last at least 15 seconds. If the colorant (a) deposited in the form of a film on the keratin material comes into contact with the flowing water, the pH of the previously preferably alkaline colorant (a) is lowered to the neutral range. In this context, it has been found that the neutral pH value is the prerequisite for immobilizing the film made up of the coloring agent (a) on the keratin material for as long as possible. If the rinsing process takes at least 15 seconds, the pH value can be reduced to be lowered sufficiently. Even better durability of the colorant is obtained, however, if the keratin material is rinsed in step (3) for more than 15 seconds. For this reason, it has been found to be very particularly preferred to rinse out the colorant (a) in step (3) of the method for a period of 30 seconds to 3 minutes and explicitly very particularly preferably from 45 seconds to 2 minutes.
- the keratin material can be dried, for example at room temperature or in a stream of air at 25 to 45 ° C.
- the method according to the invention comprises steps (1) to (3).
- step (1) the colorant (a) is applied or applied.
- the effect of the coloring agent on the keratin material in step (2) can only take place after its application.
- the coloring agent (a) is rinsed out in step (3) after it has acted in step (2).
- NBM Post-treatment agent
- the coloring agent (a) was applied to tresses of hair (Kerling, Euronaturhaar white, liquor ratio: 1 g of coloring agent (a) per g of hair tress). The agent was left on for three minutes.
- aftertreatment agent 4 g of aftertreatment agent (NBM) per g of hair tress were applied to the tresses still treated with agent (a).
- method (E1) according to the invention When carrying out method (E1) according to the invention, it was possible to achieve a color intensity which is comparable to method (V1). However, the method (E1) according to the invention comprises fewer steps and is therefore shorter and more convenient for the user than the method (V1).
