Agent for coloring keratin fibers containing pigments and C ₂ -C 3o-alkyl methicones

The present application relates to an agent for dyeing keratin fibers, in particular human hair, which contains at least one C ₂ -C 30 -alkyl methicone (a1) and at least one pigment (a2).

This application also relates to a process for dyeing keratin fibers, in particular human hair, in which first a _{ready-to-use dye is obtained by mixing a predispersion of C 2} -C 3 -alkyl methicone (a1) and pigment (a2) with a water-containing carrier formulation will be produced. This ready-to-use agent is applied to the keratin fibers, left to act and rinsed out again.

This application also relates to a multi-component packaging unit which, separately packaged in different containers, comprises two agents (I) and (II), the first agent (I) being a predispersion of C ₂ -C 30 -alkyl methicone (a1) and Pigment (a2) and the second agent (II) is a water-containing cosmetic carrier formulation.

The change in the shape and color of keratinic material, in particular human hair, represents an important area of modern cosmetics. The person skilled in the art knows various coloring systems for changing the hair color, depending on the coloring requirements. Oxidation dyes are usually used for permanent, intensive 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.

When direct dyes are used, dyes that have already been developed diffuse from the dye into the hair fiber. Compared to oxidative hair coloring, the coloring obtained with substantive dyes is less durable and can be washed out more quickly. Colorations with substantive dyes usually remain on the hair for a period of between 5 and 20 washes.

The use of color pigments is known for brief color changes on the hair and / or the skin. Color pigments are generally understood to mean insoluble, coloring substances. These are undissolved in the form of small particles in the dye formulation and are only deposited on the outside of the hair fibers and / or the surface of the skin. 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.

If the user wants particularly long-lasting coloring, the use of oxidative coloring agents has so far been his only option. However, despite multiple attempts at optimization, an unpleasant smell of ammonia or amine cannot be completely avoided with oxidative hair coloring. The hair damage still associated with the use of oxidative coloring agents also has a detrimental effect on the user's hair. The search for alternative, high-performance dyes and dyeing processes remains a challenge. Recently, there has been a particular focus on dyeing systems based on pigments.

It was the object of the present invention to provide a coloring agent which enables pigments to be fixed on the hair in an extremely permanent manner. When using the agent in a dyeing process, particularly intensive dyeing results with good leveling power and a particularly uniform color result should be achieved.

Surprisingly, it has now been found that the aforementioned object can be achieved excellently if keratin fibers, in particular hair, are colored with an agent which contains at least one C ₂ -C 3o-alkyl methicone (a1) and at least one pigment (a2) .

A first object of the present invention is an agent for coloring keratinous material, in particular human hair, containing (a1) at least one C ₂ -C 30 -alkyl methicone and (a2) at least one pigment.

In the course of the work leading to this invention, it was found that particularly good color results could be obtained if the pigment or pigments were _{predispersed by mixing with at least one C 2} -C 3 -alkyl methicone. Without being tied to this theory, it is assumed that the C ₂ -C 3o-alkyl methicones act as dispersants and wrap around the pigments in the form of a film. The pigments coated or enveloped in this way can subsequently be distributed particularly well and evenly in the colorant and can therefore be dispersed particularly well. When these coloring agents were used on strands of hair, particularly uniform coloring results were obtained. It has been shown that the C ₂ -C 3o-alkyl methicones lead to an improved uniformity of the colorations compared to other dispersants. Keratin fibers

Keratin fibers are to be understood as meaning hair, wool, furs and feathers. Keratin fibers are preferably understood to mean human hair.

Means of coloring

The term “means for coloring” is used in the context of this invention for a coloring of the keratin material, in particular the hair, caused by the use of pigments. With this coloring, the pigments are deposited as coloring compounds in a particularly homogeneous and uniform film on the surface of the keratin material.

According to the invention, the colorant is a ready-to-use agent. This ready-to-use agent can, for example, be filled into a container and applied in this form to the keratin material without further dilution, mixing or other process steps. For reasons of storage stability, however, it has been found to be very particularly preferred if the ready-to-use cosmetic agent is not produced by the hairdresser or user until shortly before use. To produce the ready-to-use agent, for example, the mixture or the predispersion of C ₂ -C 30 -alkyl methicone (a1) and pigment (a2) can be carried out with one or more other agents. This or these further agents can be, for example, a water-containing base formulation such as a cream base or a gel base. This basic formulation is then used to dilute the mixture or the predispersion of C ₂ -C 30 -alkyl methicone (a1) and pigment (a2). The mixing of C2-C30-alkyl-methicone / pigment with the base formulation can be done, for example, by spilling it and in this way ensures a particularly even distribution of the dispersed pigments in the cream base or gel base.

Furthermore, it is also conceivable to mix three or more different agents in the preparation of the _{ready-to-use coloring agent, the first agent containing C 2} -C 30 -alkyl methicone and pigment, another agent being the base formulation already described above and a the third agent contains ingredients which, for reasons of stability _{, should be stored separately from both the C 2} -C 3o-alkyl methicone / pigment and the mostly water-containing base formulation. This third agent can, for example, very particularly preferably contain amino-functionalized silicone polymers.

C ₂ -C 3o-Alkyl-Methicone (aD

As the first ingredient (a1) essential to the invention, the agent contains at least one C ₂ -C 30 -alkyl methicone. According to the invention, a C ₂ -C 30 -alkyl methicone is understood to mean a dimethicone which _{is substituted by at least one C 2} -C 30 -alkyl group. Dimethicones are alternatively also referred to as dimethylpolysiloxanes or polydimethylsiloxanes in the literature.

Represent an alkoxy group, a hydroxyl group or a hydrogen atom, x represents an integer from 0 to 1000, y represents an integer from 0 to 1000, and z represents an integer from 0 to 1000, with the proviso that

- when R2 stands for a C ₂ -C 30 -alkyl group, y stands for at least 1.

In the C ₂ -C3o alkyl Methiconen (a1) of the formula (Si-alkyl), the radicals R1, R2 and R3 independently voneinanderfüreine Ci-C3o-alkyl, Ci-C6-alkoxy group, a hydroxy group or a hydrogen atom.

The Ci-C3o-alkyl group can be linear or branched, branched alkyl groups from a chain length of at least 3 carbon atoms being possible. The methoxy group and the ethoxy group can be mentioned as examples of a C1-C6 alkoxy group.

The radicals R1, R2 and R3 are preferably, independently of one another, a linear C1-C30-alkyl group.

The radicals Ri and R3 both very particularly preferably represent a methyl group.

In the case of the C ₂ -C 3o-alkyl methicones of the formula (Si-alkyl), there is the proviso that at least one of the radicals from the group consisting of Ri, R2 and R3 stands for a C ₂ -C30-alkyl group. In this context it is particularly preferred if the radicals Ri and R3 independently of one another stand for a Ci-C3o-alkyl group and the radical R2 stands for a C ₂ -C30-alkyl group.

Furthermore, it is preferred if the radical R2 located in the middle part of the methicon stands for a C2-C30-alkyl group, more preferably for a C2-Ci8-alkyl group and particularly preferably for a C6-C10-alkyl group.

It is therefore advantageous according to the invention if the at least one pigment has an average particle size D 50 of 1.0 to 50 μm, preferably 5.0 to 45 μm, more preferably 10 to 40 μm, in particular 14 to 30 μm. The mean particle size Dso can be determined using dynamic light scattering (DLS), for example.

The pigments (a2) represent the second essential part of the agent according to the invention and are preferably used in certain quantity ranges in the agent.

Particularly good results have been obtained when the agent - based on the total weight of the agent - contains one or more pigments (a2) in a total amount of 0.01 to 10.0% by weight, preferably 0.1 to 5.0% by weight. -%, more preferably from 0.2 to 2.5% by weight and very particularly preferably from 0.25 to 1.5% by weight.

In a further very particularly preferred embodiment, an agent according to the invention is characterized in that the agent - based on the total weight of the agent - contains one or more pigments (a2) in a total amount of 0.01 to 10.0% by weight, preferably 0 .1 to 5.0% by weight, more preferably from 0.2 to 2.5% by weight and very particularly preferably from 0.25 to 1.5% by weight.

In a further very particularly preferred embodiment, an agent according to the invention is characterized in that the agent - based on the total weight of the agent - prefers one or more inorganic pigments (a2) in a total amount of 0.01 to 10.0% by weight 0.1 to 5.0% by weight, more preferably from 0.2 to 2.5% by weight and very particularly preferably from 0.25 to 1.5% by weight.

In a further very particularly preferred embodiment, an agent according to the invention is characterized in that the agent - based on the total weight of the agent - prefers one or more organic pigments (a2) in a total amount of 0.01 to 10.0% by weight 0.1 to 5.0% by weight, more preferably from 0.2 to 2.5% by weight and very particularly preferably from 0.25 to 1.5% by weight. amino-functionalized silicone pads (a3)

By using the combination of C ₂ -C 30 -alkyl methicone (a1) and pigment (a2) on average, color results can be obtained which are characterized by particularly high uniformity or particularly good leveling.

Depending on the intended use of the agent, the user would like colorations in different color intensities. For the nuance of hair, for example in pastel shades or inconspicuous natural nuances, it can be sufficient to use only a mixture of (a1) and (a2) in the middle. In some cases, for example when particularly conspicuous fashion nuances are to be produced, it may be necessary, however, to achieve the highest possible color intensity with the pigment-based colorant. For this purpose it has proven to be particularly preferred to add at least one amino-functionalized silicone polymer (a3) to the agent as a further component. The amino-functionalized silicone polymer can alternatively also be referred to as aminosilicone or amodimethicone.

Silicone polymers are generally macromolecules with a molecular weight of at least 500 g / mol, preferably at least 1000 g / mol, more preferably at least 2500 g / mol, particularly preferably at least 5000 g / mol, which comprise repeating organic units.

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 not more than 10 ⁷ g / mol, preferably not more than 10 ⁶ g / mol and particularly preferably not more than 10 ⁵ g / mol.

The silicone polymers comprise many Si — O repeating units, it being possible for the Si atoms to carry organic radicals such as, for example, alkyl groups or substituted alkyl groups. Alternatively, a silicone polymer is therefore also referred to as a polydimethylsiloxane. In accordance with the high molecular weight of the silicone polymers, they are based on more than 10 Si-O repeat units, preferably more than 50 Si-O repeat units and particularly preferably more than 100 Si-O repeat units, very particularly preferably more than 500 Si-O repeat units .

An amino-functionalized silicone polymer is understood to mean a functionalized silicone which carries at least one structural unit with an amino group. The amino-functionalized silicone polymer preferably carries a plurality of structural units each with at least one amino group. An amino group is understood to mean a primary amino group, a secondary amino group and a tertiary amino group. All of these amino groups can be protonated in an acidic medium and are then in their cationic form.

In principle, good effects could be achieved with amino-functionalized silicone polymers (a3) if they carry at least one primary, at least one secondary and / or at least one tertiary amino group. However, colorations with the highest color intensities were observed when an amino-functionalized silicone polymer (a3) was used which contains at least one secondary amino group.

In a very particularly preferred embodiment, an agent according to the invention is characterized in that it additionally

(a2) at least one pigment and

(A3) at least one amino-functionalized silicone polymer, which is derived from the C ₂ -C3o-alkyl

ALK1 and ALK2 independently of one another for a linear or branched, bivalent Ci-

C2o-alkylene group. The positions marked with an asterisk (*) indicate the bond to further structural units of the silicone polymer. For example, the silicon atom adjacent to the star can be bonded to a further oxygen atom, and the oxygen atom adjacent to the star can be bonded to a further silicon atom or to a Ci-C6-alkyl group.

A divalent Ci-C2o-alkylene group can alternatively also be referred to as a divalent or divalent Ci-C2o-alkylene group, which means that each grouping ALK1 or AK2 can form two bonds.

In the case of ALK1, there is a bond from the silicon atom to the ALK1 group, and the second bond is between ALK1 and the secondary amino group.

In the case of ALK2, one bond is from the secondary amino group to the ALK2 moiety, and the second bond is between ALK2 and the primary amino group.

Examples of a linear divalent Ci-C2o-alkylene group are, for example, the methylene group (-CH2-), the ethylene group (-CH2-CH2-), the propylene group (-CH2-CH2-CH2-) and the butylene group (-CH2- CH2-CH2-CH2-). The propylene group (-CH2-CH2-CH2-) is particularly preferred. From a chain length of 3 carbon atoms, divalent alkylene groups can also be branched. Examples of branched, divalent C3-C2o-alkylene groups are (-CF -CF CF) -) and (-CH2-CH (CH3) -CH2-).

In a further particularly preferred embodiment, the structural units of the formula (Si-amino) represent repeat units in the amino-functionalized silicone polymer (a3), so that the silicone polymer comprises several structural units of the formula (Si-amino).

Particularly suitable amino-functionalized silicone polymers (a3) with at least one secondary amino group are listed below.

The silicones of the formulas (Si-III) and (Si-IV) differ in the grouping on the Si atom that carries the nitrogen-containing group: In formula (Si-III), R2 denotes a hydroxyl group or a C1-4 alkoxy group, while the remainder in formula (Si-IV) is a methyl group. The individual Si groupings, which are marked with the indices m and n or p and q, do not have to be present as blocks, rather the individual units can also be present in a statistically distributed manner, ie in the formulas (Si-III) and (Si IV) not necessarily every R1-Si (CH3) ₂ group is bound to a - [0-Si (CH3) ₂ ] group.

A Ci ₂ -C 30 fatty acid diglyceride is understood to mean the diester of the trihydric alcohol glycerol with two equivalents of fatty acid. Either the middle and one terminal hydroxyl group of the glycerol can be esterified with two equivalents of fatty acid, or both terminal hydroxyl groups of the glycerol are esterified with one fatty acid each. The glycerine can be esterified with two structurally identical as well as with two different fatty acids. The fatty acid diglycerides are particularly suitable in which at least one of the ester groups is formed from glycerol with a fatty acid selected from dodecanoic acid (lauric acid), tetradecanoic acid (myristic acid), hexadecanoic acid (palmitic acid), tetracosanoic acid (lignoceric acid), octadecanoic acid (Stearic acid), eicosanoic acid (arachidic acid), docosanoic acid (behenic acid), petroselinic acid [(Z) -6-octadecenoic acid], palmitoleic acid [(9Z) -hexadec-9-enoic acid], oleic acid [(9Z) -octadec-9-enoic acid] , Elaidic acid [(9E) - octadec-9-enoic acid], erucic acid [(13Z) -Docos-13-enoic acid], linoleic acid [(9Z, 12Z) -octadeca-9,12-dienoic acid, linolenic acid [(9Z, 12Z, 15Z) -Octadeca-9,12,15-trienoic acid, eleostearic acid [(9Z, 11 E, 13E) -Octadeca-9,11, 3-trienoic acid], arachidonic acid [(5Z, 8Z, 11Z, 14Z) -lcosa-5 , 8,11, 14-tetraenoic acid] and / or nervonic acid [(15Z) -Tetracos-15-enoic acid]

It has proven to be preferred to use one or more Ci ₂ -Ö30-Fettsäuremono-, Ci ₂ -Ö3o-Fettsäuredi- and / or Ci ₂ -Ö3o-Fettsäuretriglyceride (a4) in very specific quantity ranges on average.

With a view to solving the problem according to the invention, it has proven to be advantageous if the agent - based on the total weight of the agent - has one or more C12-030 fatty acid _{mono-, Ci 2} -Ö3o-Fettsäureddi and / or Ci ₂ -Ö3o -Fatty acid triglycerides (a4) in a total amount of 0.1 to 20.0% by weight, preferably 0.3 to 15.0% by weight, more preferably 0.5 to 10.0% by weight and very particularly preferably from 0.8 to 5.0% by weight.

The Ci ₂ -C30 fatty acid mono-, Ci ₂ -C3o fatty acid di- and / or Ci ₂ -C3o fatty acid triglycerides can be used as sole fat constituents (a4) in the agents. According to the invention, however, at least one Ci ₂ -C30 fatty acid mono-, Ci ₂ -C3o fatty acid and / or C12-C30 fatty acid triglyceride in combination with at least one Ci ₂ -C30 fatty alcohol can be incorporated into the agent.

Furthermore, as a very particularly preferred fat component, the agent can also contain at least one hydrocarbon.

Hydrocarbons are compounds with 8 to 80 C atoms consisting exclusively of the atoms carbon and hydrogen. In this context, aliphatic hydrocarbons such as mineral oils, liquid paraffin oils (e.g. Paraffinium Liquidum or Paraffinum Perliquidum), isoparaffin oils, semi-solid paraffin oils, paraffin waxes, hard paraffin (Paraffinum Solidum), petrolatum and polydecene are particularly preferred.

Liquid paraffin oils (Paraffinum Liquidum and Paraffinium Perliquidum) have proven to be particularly suitable in this context. The hydrocarbon is very particularly preferably Paraffinum Liquidum, also called white oil. Paraffinum Liquidum is a mixture of purified, saturated, aliphatic hydrocarbons, which for the most part consists of hydrocarbon chains with a carbon chain distribution of 25 to 35 carbon atoms.

Particularly good results were obtained when the agent contained at least one hydrocarbon selected from the group of mineral oils, liquid paraffin oils, isoparaffin oils, semi-solid paraffin oils, paraffin waxes, hard paraffin (Paraffinum Solidum), petrolatum and polydecene.

In a particularly preferred embodiment, an agent according to the invention is characterized in that it contains at least one fat component from the group of hydrocarbons.

Due to the optional but preferred content of water and fat constituents, the agent according to the invention is particularly preferably in the form of an emulsion. In order to further optimize the formation of the emulsion, it has proven to be very particularly preferred to continue to use at least one surfactant on average.

The agent therefore very particularly preferably additionally contains at least one surfactant.

In the context of a further particularly preferred embodiment, an agent according to the invention is characterized in that it contains at least one surfactant.

The term surfactants (T) is understood to mean surface-active substances which form adsorption layers on surfaces and interfaces or which can aggregate in volume phases to form micellar colloids or lyotropic mesophases. A distinction is made between anionic surfactants consisting of a hydrophobic residue and a negatively charged hydrophilic head group, amphoteric surfactants, which carry both a negative and a compensating positive charge, cationic surfactants, which have a positively charged hydrophilic group in addition to a hydrophobic residue, and nonionic surfactants, which have no charges but rather strong dipole moments and are strongly hydrated in aqueous solution.

In a particularly preferred embodiment, an agent according to the invention is characterized in that it contains at least one nonionic surfactant. Nonionic surfactants contain, for example, a polyol group, a polyalkylene glycol ether group or a combination of polyol and polyglycol ether groups as the hydrophilic group. Such connections are for example

Adducts of 2 to 50 moles of ethylene oxide and / or 0 to 5 moles of propylene oxide with linear and branched fatty alcohols with 6 to 30 carbon atoms, the fatty alcohol polyglycol ethers or the fatty alcohol polypropylene glycol ethers or mixed fatty alcohol polyethers,

Adducts of 2 to 50 moles of ethylene oxide and / or 0 to 5 moles of propylene oxide with linear and branched fatty acids with 6 to 30 carbon atoms, the fatty acid polyglycol ethers or the fatty acid polypropylene glycol ethers or mixed fatty acid polyethers,

They can be obtained by the relevant methods of preparative organic chemistry. The alkyl and alkenyl oligoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably from glucose. The preferred alkyl and / or alkenyl oligoglycosides are thus alkyl and / or alkenyl oligoglucosides. The index number p in the general formula (Tnio-2) indicates the degree of oligomerization (DP), ie the distribution of mono- and oligoglycosides, and stands for a number between 1 and 10. While p in the individual molecule must always be an integer and here can assume the values p = 1 to 6 in particular, the value p for a specific alkyl oligoglycoside is an analytically determined mathematical variable that usually represents a fractional number. Alkyl and / or alkenyl oligoglycosides with an average degree of oligomerization p of 1.1 to 3.0 are preferably used. From an application point of view, those alkyl and / or alkenyl oligoglycosides whose degree of oligomerization is less than 1.7 and in particular between 1.2 and 1.4 are preferred. The alkyl or alkenyl radical R ⁴ can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, caproic alcohol, caprylic alcohol, capric alcohol and undecyl alcohol and their technical mixtures, such as are obtained, for example, in the hydrogenation of technical fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxo synthesis. Alkyl oligoglucosides of chain length Cs-Cio (DP = 1 to 3) are preferred, which are obtained as first runnings in the distillative separation of technical Cs-Cis coconut fatty alcohol and are contaminated with a proportion of less than 6% by weight Ci2 alcohol can as well as alkyl oligoglucosides based on technical Cg / n-oxo alcohols (DP = 1 to 3). The alkyl or alkenyl radical R ¹⁵ can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms. Typical examples are lauryl alcohol, myristyl alcohol, cetyl alcohol, palmoleyl alcohol, stearyl alcohol, isostearyl alcohol, oleyl alcohol, elaidyl alcohol, petroselinyl alcohol, arachyl alcohol, gadoleyl alcohol, behenyl alcohol, erucyl alcohol, brassidyl alcohol and their technical mixtures can be obtained as described above. Alkyl oligoglucosides based on hardened C12 / 14 coconut alcohol with a DP of 1 to 3 are preferred.

Sugar surfactants of the fatty acid N-alkyl polyhydroxyalkylamide type, a nonionic surfactant of the formula (Tnio-3),

R ⁵ CO-NR ⁶ - [Z] (Tnio-3) in which R ⁵ CO stands for an aliphatic acyl radical with 6 to 22 carbon atoms, R ⁶ for hydrogen, an alkyl or hydroxyalkyl radical with 1 to 4 carbon atoms and [Z] for a linear or branched polyhydroxyalkyl radical with 3 to 12 carbon atoms and 3 to 10 hydroxyl groups stands. The fatty acid N-alkyl polyhydroxyalkylamides are known substances which can usually be obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride. The fatty acid N-alkyl polyhydroxyalkylamides are preferably derived from reducing sugars having 5 or 6 carbon atoms, in particular from glucose. The preferred fatty acid N-alkyl polyhydroxyalkylamides are therefore fatty acid N-alkyl glucamides, as represented by the formula (Tnio-4):

R ⁷ CO- (NR ⁸ ) -CH ₂ - [CH (OH)] ₄ - CH ₂ OH (Tnio-4)

Glucamides of the formula (Tnio- 4), in which R ^{8 stands} for hydrogen or an alkyl group and R ⁷ CO for the acyl radical of caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, palm oleic acid, are preferably used as fatty acid N-alkyl polyhydroxyalkylamides. Stearic acid, isostearic acid, oleic acid, elaidic acid, petroselic acid, linoleic acid, linolenic acid, arachidic acid, gadoleic acid, behenic acid or erucic acid or technical mixtures thereof. Fatty acid N-alkyl glucamides of the formula (Tnio-4), which are obtained by reductive amination of glucose with methylamine and subsequent acylation with lauric acid or C12 / 14 coconut fatty acid or a corresponding derivative, are particularly preferred. Furthermore, the polyhydroxyalkylamides can also be derived from maltose and palatinose.

The sugar surfactants can be contained in the agents used according to the invention preferably in amounts of 0.1-20% by weight, based on the total agent. Quantities of 0.5-15% by weight are preferred, and quantities of 0.5-7.5% by weight are very particularly preferred.

Further typical examples of nonionic surfactants are fatty acid amide polyglycol ethers, fatty amine polyglycol ethers, mixed ethers or mixed formals, protein hydrolyzates (in particular vegetable products based on wheat) and polysorbates.

The alkylene oxide addition products with saturated linear fatty alcohols and fatty acids with 2 to 30 moles of ethylene oxide per mole of fatty alcohol or fatty acid and the sugar surfactants have proven to be preferred nonionic surfactants. Preparations with excellent properties are also obtained if they contain fatty acid esters of ethoxylated glycerol as nonionic surfactants. These connections are characterized by the following parameters. The alkyl radical R contains 6 to 22 carbon atoms and can be either linear or branched. Primary linear and methyl-branched aliphatic radicals in the 2-position are preferred. Such alkyl radicals are, for example, 1-octyl, 1-decyl, 1-lauryl, 1-myristyl, 1-cetyl and 1-stearyl. 1-Octyl, 1-decyl, 1-lauryl and 1-myristyl are particularly preferred. When using so-called "oxo alcohols" as starting materials, compounds with an odd number of carbon atoms in the alkyl chain predominate.

The compounds with alkyl groups used as surfactants can each be uniform substances. However, it is generally preferred to start with native vegetable or animal raw materials in the production of these substances, so that substance mixtures with different alkyl chain lengths depending on the respective raw material are obtained.

In the case of surfactants which are addition products of ethylene and / or propylene oxide with fatty alcohols or derivatives of these addition products, both products with a “normal” homolog distribution and those with a narrowed homolog distribution can be used. “Normal” homolog distribution is understood to mean mixtures of homologs which are obtained in the reaction of fatty alcohol and alkylene oxide using alkali metals, alkali metal hydroxides or alkali metal alcoholates as catalysts. On the other hand, narrow homolog distributions are obtained if, for example, hydrotalcites, alkaline earth metal salts of ether carboxylic acids, alkaline earth metal oxides, hydroxides or alcoholates are used as catalysts. The use of products with a narrow homolog distribution can be preferred.

Particularly good results were obtained when an agent (b) which contained at least one ethoxylated fatty alcohol with a degree of ethoxylation of 80 to 120 was used in the process according to the invention.

A particularly suitable nonionic surfactant of this type is ceteareth-30. Ceteareth-30 is a mixture of cetyl alcohol and stearyl alcohol, each of which is ethoxylated with 30 units of ethylene oxide. The mixture of cetyl alcohol and stearyl alcohol is called cetearyl alcohol. Ceteareth-30 has the CAS number 68439- 49-6 and can be purchased from BASF, for example, under the trade name Eumulgin B3.

It has proven to be very particularly preferred if the agent contains both at least one nonionic surfactant of the formula (Tl) and at least one nonionic surfactant of the formula (T-II). Solvent on average

Method of coloring keratin material

The agents described above can be used excellently in processes for coloring keratinic material, in particular human hair.

A second object of the present invention is therefore a method for dyeing keratin fibers, in particular human hair, in which an agent, as disclosed in the description of the first subject of the invention in detail, is applied to the keratin fibers and optionally after an exposure time of Rinsing out again for 30 seconds to 45 minutes.

In other words, a second subject of the invention is a method for coloring keratinic material, in particular human hair, comprising the following steps:

(1) Application of a coloring agent to the keratinous material, the coloring agent being an agent as disclosed in detail in the description of the first subject matter of the invention,

(2) action of the coloring agent on the keratinic material and

(3) Rinse the dye out with water.

In step (1) of the method according to the invention, the agent of the first subject matter of the invention is applied to the keratinic material, which is very particularly preferably human hair.

In step (2) of the method according to the invention, the agent is then allowed to act on the keratinic material after its application. In this context, different exposure times of, for example, 30 seconds to 60 minutes are conceivable.

A great advantage of the dyeing system according to the invention, however, is that an intense color result can be achieved even in very short periods of time after short exposure times. For this reason, it is advantageous if the application mixture remains on the keratin material for comparatively short periods of time from 30 seconds to 15 minutes, preferably from 30 seconds to 10 minutes, and particularly preferably from 1 to 5 minutes after its application. In a further preferred embodiment, a method according to the invention is characterized by

(2) Acting of the coloring agent on the keratinic material for a period of 30 seconds to 15 minutes, preferably from 30 seconds to 10 minutes, and particularly preferably from 1 to 5 minutes.

After the application mixture has acted on the keratin material, it is finally rinsed out with water in step (3) of the method.

In one embodiment, the application mixture can only be washed out with water, i.e. without the aid of an aftertreatment agent or a shampoo. The use of an aftertreatment agent or conditioner in step (6) is also conceivable in principle.

To solve the problem according to the invention and to increase the ease of use, however, it has been found to be particularly preferred to rinse out the agent in step (3) exclusively with water without the aid of a further aftertreatment agent, shampoo or conditioner.

In a further preferred embodiment, a method according to the invention is characterized by

(3) Rinse the dye out with water only.

Method for coloring keratin material, in which first the ready-to-use agent is produced.

As already described above, the agent of the first subject matter of the invention is a ready-to-use agent that is either made available to the user directly in its ready-to-use form, or that is produced shortly before use by mixing different agents.

In order to ensure a particularly fine distribution of the pigments, it has been found to be particularly preferred to produce the ready-to-use agent shortly before use by mixing two or three different agents.

In a particularly preferred embodiment, the ready-to-use agent is accordingly produced by mixing at least two different agents, the first of these two agents being the mixture of C ₂ -C 30 -alkyl methicone (s) (a1) and pigment (s) (a2 ) includes. The second agent is a water-based, cosmetic carrier formulation, which can additionally contain one or more of the optional ingredients as described in the description of the first subject matter of the invention were disclosed. For example, the carrier formulation can contain at least one fat component and / or at least one surfactant and / or at least one amino-functionalized silicone polymer (a3).

The present application therefore also relates to a method for dyeing keratinic fibers, in particular human hair, comprising the following steps:

(1) Provision of an agent (I), the agent (I) containing:

(a1) at least one C ₂ -C 3o-alkyl methicone and

(a2) at least pigment,

(2) Provision of an agent (II), the agent (II) being a water-based, cosmetic carrier formulation,

(3) Preparation of an application mixture by mixing agents (I) and (II),

(4) applying the application mixture prepared in step (3) to the keratinous material,

(5) action of the application mixture applied in step (4) on the keratinic material and

(6) Rinsing out the application mixture with water, ingredients (a1) and (a2) being disclosed in detail in the description of the first subject matter of the invention.

That is particularly preferred

(2) Provision of an agent (II), the agent (II) containing water and containing at least one fat component and / or at least one surfactant.

Also particularly preferred is that

(2) Provision of an agent (II), the agent (II) containing water and containing at least one amino-functionalized silicone polymer (a3)).

The agent (I) here preferably represents a predispersion of the pigments (a2) in the C ₂ -C 30 -alkyl methicone (a1), which can be in the form of a concentrate, for example.

The agent (II) is a basic formulation, which is preferably in the form of a basic cream. If the agents (I) and (II) are mixed, the predispersion of the pigments (a2) in the C2-C30-alkyl methicone (a1) ensures a particularly fine distribution of the pigments, even after the two agents (I) and (II) is retained in the ready-to-use agent.

In particular if, in addition to C ₂ -C 30 -alkyl methicone (s) (a1) and pigment (s) (a2), at least one amino-functionalized silicone polymer (a3) is also used in the dyeing process should find, it makes sense to separate component (a3) from (a1) / (a2) during storage. In this case (a3) is only mixed with (a1) / (a2) and with the basic formulation shortly before use.

Depending on the selected pH value, the aminosilicone (a3) has in some cases shown a reduced storage stability in an aqueous medium. In these cases it can be advantageous to pack the amino-functionalized silicone polymer (a3) in a separate agent and to prepare both the predispersion (a1) / (a2) and the amino silicone (a3) with a basic formulation shortly before use to mix. In this case, at least three different agents are mixed with one another to produce the ready-to-use coloring agent.

Another subject matter is therefore a method for dyeing keratin fibers, in particular human hair, comprising the following steps:

(1) Provision of an agent (I), the agent (I) containing:

(a1) at least one C ₂ -C 3o-alkyl methicone and

(a2) at least pigment,

(3) Provision of an agent (III), the agent (III) containing:

(a3) at least one amino-functionalized silicone polymer (a3),

(4) Preparation of an application mixture by mixing agents (I) and (II) and

(III),

(5) applying the application mixture prepared in step (4) to the keratinic material,

(6) Action of the application mixture applied in step (5) on the keratinic material and

(7) Rinsing the application mixture with water, ingredients (a1), (a2) and (a3) being disclosed in detail in the description of the first subject matter of the invention.

In the context of this embodiment, the agent (I) preferably represents a predispersion of the pigments (a2) in the C ₂ -C 30 -alkyl methicone (a1), which can be in the form of a concentrate, for example. The agent (III) is preferably also a concentrate which contains the amino-functionalized silicone polymer (s) (a3).

Before use, the two agents or concentrates (I) and (III) are then mixed with the carrier formulation (II). The order of mixing is arbitrary. Thus, the means (I) and (II) can first be mixed with one another, whereupon this mixture is then mixed with the means (III). It is also conceivable to first mix means (II) and (III) and then to mix this mixture with the agent (I). All three agents (I), (II) and (III) can also be added together and then mixed by shaking or stirring.

The carrier formulation contains water and preferably has a high water content. The optionally usable further ingredients of the first subject matter of the invention can also be contained in this carrier formulation.

Here, too, is particularly preferred

Predispersing the pigments (a2) in the C2-C30-Alkvmethicone (a1)

As already described above, it is particularly preferred to first prepare a predispersion from pigment (s) (a2) and C2-C3o-alkymethicone (a1).

For this purpose, pigment and C ₂ -C 30 alkymethicone can be mixed using a stirrer. Particularly good mixing can be achieved if an ultrathorax mixer is used as the mixer.

As a mixing ratio of pigment (a2) to C ₂ -C 30 alkymethicone (a1), for example 1 part by weight of pigment (s) (a2) can be selected, which are mixed with 2 to 6 parts by weight of C2-C30 alkymethicone (a1).

Multi-component packaging unit

To increase user comfort, the means described above can be made available to the user in the form of a multi-component packaging unit.

Another object is therefore a multi-component packaging unit (kit-of-parts) for coloring keratinic fibers, in particular human hair, comprehensively packaged separately from one another

- A first container with a means (I), the means (I) containing:

(a1) at least one C ₂ -C 3o-alkyl methicone and

(a2) at least pigment,

- A second container with an agent (II), the agent (II) being a water-containing, cosmetic carrier formulation, the ingredients (a1) and (a2) being defined in claims 1 to 12.

A multi-component packaging unit (kit-of-parts) comprising - A second container with an agent (II), the agent (II) containing water and containing at least one fat component and / or at least one surfactant.

Furthermore, a multi-component packaging unit is very particularly preferably packaged comprehensively and separately
