The present disclosure relates to a cosmetic agent for treating a keratinous material, wherein the cosmetic agent is a fluid and comprises at least one organic silicon compound, bis(triethoxysilylpropyl)amine, and at least one polyvalent metal cation, and to the use of the cosmetic agent.
Cosmetic treatment of skin and hair is an important part of human body care. Thus, human hair today is treated in many ways with hair cosmetic preparations. This includes, for example, cleaning the hair with shampoos, care and regeneration with conditioners and cures, and bleaching, coloring, and shaping the hair with dyes, tints, waving agents and styling products. Employing ways changing or nuancing the color of the hair on the head play a special role. If we disregard bleaching agents, which cause oxidative lightening of the hair by breaking down the natural hair dyes, there are essentially three types of hair dyes that are important in the field of hair coloring: So-called oxidation dyes are used for durable, intensive dyeing with corresponding fastness properties. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components.
If the dyes formed or directly used during color formation exhibit markedly different fastness properties (e.g., UV stability, fastness to perspiration, fastness to washing, etc.), a discernible and therefore undesirable color shift may occur over time. Frequent washing or other care treatments can also cause color shifts. This phenomenon occurs more when the hairstyle has hair or hair zones of different degrees of damage. An example of this is long hair, where the tips of the hair, which have been exposed to all kinds of environmental influences for a long time, are usually much more damaged than the relatively freshly regrown hair zones.
For temporary staining, staining or tinting agents are usually used that contain so-called direct pullers as the staining component. These are dye molecules that are absorbed directly onto the hair and do not require an oxidative process to form the color. These colorations are usually much more sensitive to shampooing than the oxidative colorations, so that in many cases an undesirable shift in nuance or even a visible “decolorization” occurs much more quickly.
In another common dyeing process, precursors of the natural hair dye melanin are applied to the hair; these then form natural analogous dyes as part of oxidative processes in the hair. In such processes, for example, 5,6-dihydroxyindoline is used as a dye precursor. With, especially multiple, application of agents containing 5,6-dihydroxyindoline it is possible to restore the natural hair color to people with graying hair. The coloration can be carried out with atmospheric oxygen as the only oxidizing agent, so that no further oxidizing agents must be used.
With all hair coloring occur several problems. On the one hand, undesirable staining of skin areas may occur when the hair dye is rinsed out. This effect can also cause lighter “highlights” to be recolored by the hair color when washed out, or the dye to stain the lighter base hair when washed out from darker “highlights”. Washing out dyes is generally associated with the disadvantage that the originally desired color changes. Especially hair colors with red or blue tones have a shortened residence time in the hair, so that their washout lead to undesirable colors. This problem is also counteracted by color protection products.
On the other hand, all chemical stresses mean a complication of dyeing processes. The external exposure of hair to chemicals from a variety of different sources poses challenges for the development of cosmetic coloring products. Air and water impurities have a detrimental effect on skin and hair. Major air pollutants include polycyclic aromatic hydrocarbons, volatile organic compounds, nitrogen oxides (NOx), particulate matter, and cigarette smoke. The effect of various air pollutants can be enhanced in the presence of other air pollutants and when exposed to UV radiation.
There is therefore a need for products that bring about a special care effect for hair to allow optimal coloring processes and ensure that the hair at the same time maintain a long-lasting, desired color.
This disclosure provides a cosmetic composition for treating a keratinous material, wherein the cosmetic composition is a fluid, and comprises at least one organic silicon compound comprising one to three silicon atoms, and at least one polyvalent metal cation in a molar concentration of from about 0.001 mol/L to about 2 mol/L.
The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the subject matter as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.
The task underlying the present disclosure is to provide a product with an improved care and/or protection effect. In particular, the present disclosure was based on the task of providing a cosmetic composition that gives special care to damaged hair and reduces the effect of washout or color change.
This task is solved by a cosmetic agent for treating a keratinous material, wherein the cosmetic agent is a fluid, and
a) at least one organic silicon compound containing one to three silicon atoms, and
b) comprises at least one polyvalent metal cation in a molar concentration of about 0.001 mol/L to about 2 mol/L, preferably from about 0.005 mol/L to about 1.5 mol/L, more preferably from about 0.01 to about 1 mol/L, most preferably from about 0.02 to about 0.5 mol/L.
By a keratinous material is meant hair, the skin, the nails (such as fingernails and/or toenails). Wool, furs, and feathers also fall under the definition of keratinous material.
Preferably, a keratinous material is understood to mean human hair, human skin, and human nails, in particular fingernails and toenails. Very preferably, keratinous material is understood to mean human hair, in particular head and/or beard hair.
As a first ingredient essential to the disclosure, the cosmetic composition for treating a keratinous material contains at least one organic silicon compound containing one to three silicon atoms. Preferred organic silicon compounds are selected from silanes having one, two or three silicon atoms, wherein the organic silicon compound comprises one or more hydroxyl groups and/or hydrolyzable groups per molecule.
Organic silicon compounds, alternatively called organosilicon compounds, are compounds which either have a direct silicon-carbon bond (Si—C) or in which the carbon is bonded to the silicon atom via an oxygen, nitrogen, or sulfur atom. The organic silicon compounds are compounds containing one to three silicon atoms. Organic silicon compounds preferably contain one or two silicon atoms.
According to IUPAC rules, the term silane stands for a group of chemical compounds based on a silicon skeleton and hydrogen. In organic silanes, the hydrogen atoms are completely or partially replaced by organic groups such as (substituted) alkyl groups and/or alkoxy groups. In organic silanes, some of the hydrogen atoms may also be replaced by hydroxy groups.
The agent for treating a keratinous material contains at least one organic silicon compound preferably selected from silanes having one, two or three silicon atoms, wherein the organic silicon compound comprises one or more hydroxyl groups or hydrolyzable groups per molecule.
In a most preferred embodiment, the agent for treating a keratinous material comprises at least one organic silicon compound selected from silanes having one, two or three silicon atoms, wherein the organic silicon compound further comprises one or more basic groups and one or more hydroxyl groups or hydrolyzable groups per molecule.
This basic group can be, for example, an amino group, an alkylamino group or a dialkylamino group, which is preferably connected to a silicon atom via a linker. The basic group is preferably an amino group, a C1-C6 alkylamino group or a di(C1-C6)alkylamino group.
The hydrolyzable group(s) is (are) preferably a C1-C6 alkoxy group, especially an ethoxy group or a methoxy group. It is preferred when the hydrolyzable group is directly bonded to the silicon atom. For example, if the hydrolyzable group is an ethoxy group, the organic silicon compound preferably contains a structural unit R′R″R″′Si—O—CH2—CH3. The residues R′, R″ and R″′ represent the three remaining free valences of the silicon atom.
Particularly good results were obtained when the agent for treating a keratinous material contains at least one organic silicon compound of formula (I) and/or (II).
The compounds of formulae (I) and (II) are organic silicon compounds selected from silanes having one, two or three silicon atoms, the organic silicon compound comprising one or more hydroxyl groups and/or hydrolysable groups per molecule.

The best protection against the negative effects of water and/or air pollution (“anti-pollution” effect) and the best care of stressed hair could be obtained if the agent for treating a keratinous material contains at least one organic silicon compound of formula (I) in which the radicals R3, R4 independently represent a methyl group or an ethyl group.
Particularly well-suited organic silicon compounds of formula (I) are
The organic silicon compound of formula (I) is commercially available. (3-aminopropyl)trimethoxysilane, for example, can be purchased from Sigma-Aldrich. (3-Aminopropyl)triethoxysilane is also commercially available from Sigma-Aldrich.
In another embodiment, the composition for treating a keratinous material comprises at least one organic silicon compound of formula (II)
(R5O)c(R6)dSi-(A)c-[NR7-(A′)]f—[O-(A″)]g—[NR8-(A″′)]h-Si(R6′)d′(OR5′)c′ (II),
The organosilicon compounds of formula (II) each bear at their two ends the silicon-containing groupings (R5O)c(R6)dSi— and —Si(R6′)d′(OR5′)c′.
In the central part of the molecule of formula (II) there are the groups -(A)e- and —[NR7-(A′)]f—
and —[O-(A″)]g- and —[NR8-(A″′)]h-. Here, each of the radicals e, f, g, and h can independently of one another stand for the number about 0 or about 1, with the proviso that at least one of the radicals e, f, g, and h is different from about 0. In other words, an organic silicon compound of formula (II) contains at least one grouping selected from the group including -(A)- and —[NR7-(A′)]- and —[O-(A″)]- and —[NR8-(A″′)]-.
In the two terminal structural units (R5O)c(R6)dSi— and —Si(R6′)d′(OR5′)c, the radicals R5, R5′, R5″ independently of one another represent a hydrogen atom or a C1-C6 alkyl group. The radicals R6, R6′ and R6″ independently represent a C1-C6 alkyl group.
Here a stands for an integer from about 1 to about 3, and d stands for the integer about 3−c. If c stands for the number about 3, then d is equal to about 0. If c stands for the number about 2, then d is equal to about 1. If c stands for the number about 1, then d is equal to about 2.

In another preferred one, the agent for treating a keratinous material comprises at least one organic silicon compound of formula (II)

where
R5 and R5′ independently represent a methyl group or an ethyl group,
c and c′ both stand for the number about 3 and
d and d′ both stand for the number about 0.
When c and c′ both represent the number about 3 and d and d′ both represent the number about 0, the organic silicon compounds correspond to formula (IIa)
(R5O)3Si-(A)c-[NR7-(A′)]f—[O-(A″)]g—[NR8-(A″′)]h-Si(R5′)3 (IIa).
The radicals e, f, g, and h can independently stand for the number about 0 or about 1, whereby at least one radical from e, f, g, and h is different from about zero. The abbreviations e, f, g, and h thus define which of the groupings -(A)e- and -[NR7-(A′)]f- and —[O-(A″)]g- and -[NR8-(A″′)]h- are in the middle part of the organic silicon compound of formula (II).
In this context, the presence of certain groupings has proven to be particularly beneficial in terms of increasing the “anti-pollution” effect. Particularly good results were obtained when at least two of the residues e, f, g, and h stand for the number about 1. Especially preferred e and f both stand for the number about 1. Furthermore, g and h both stand for the number about 0.
When e and f are both about 1 and g and h are both about 0, the organic silicon compounds are represented by the formula (IIb)
(R5O)c(R6)dSi-(A)-[NR7-(A′)]-Si(R6′)d′(OR5′)c′ (IIb).
The radicals A, A′, A″, A″′ and A″ ″ independently represent a linear or branched two band C1-C20 alkylene group. Preferably the radicals A, A′, A″, A″′ and A″ ″ independently of one another represent a linear, two band C1-C20 alkylene group. Further preferably the radicals A, A′, A″, A″′ and A″ ″ independently represent a linear two band C1-C6 alkylene group. In particular, the radicals A, A′, A″, A″′ and A″ ″ independently of one another represent a methylene group (—CH2—), an ethylene group (—CH2—CH2—), a propylene group (—CH2—CH2—CH2—) or a butylene group (—CH2—CH2—CH2—CH2—). In particular, the residues A, A′, A″, A″′ and A″ ″ stand for a propylene group (—CH2—CH2—CH2—).
When the radical f represents the number about 1, the organic silicon compound of formula (II) contains a structural grouping —[NR7-(A′)]-.
When the radical h represents the number about 1, the organic silicon compound of formula (II) contains a structural grouping —[NR8-(A″)]-.
Wherein R7 and R7 independently represent a hydrogen atom, a C1-C6 alkyl group, a hydroxy-C1-C6 alkyl group, a C2-C6 alkenyl group, an amino-C1-C6 alkyl group or a group of the formula (III)
-(A″″)-Si(R6″)d″(OR5″)c″ (III).
Very preferably, R7 and R8 independently represent a hydrogen atom, a methyl group, a 2-hydroxyethyl group, a 2-alkenyl group, a 2-aminoethyl group or a group of formula (III).
When the radical f represents the number about 1 and the radical h represents the number about 0, the organic silicon compound contains the grouping [NR7-(A′)] but not the grouping —[NR8-(A″)]. If the radical R7 now stands for a grouping of the formula (III), the agent for treating a keratinous material contains an organic silicon compound with about 3 reactive silane groups.
In another preferred one, the agent for treating a keratinous material comprises at least one organic silicon compound of formula (II)

Organic silicon compounds of the formula (IV) that are particularly suitable for solving the problem are
The organic silicon compounds described above are reactive compounds.
In this context, it has been found to be quite preferred if the agent contains as organic silicon compound (3-aminopropyl)triethoxysilane, i.e., an aminopropyltriethoxysilane (AMEO), and/or 3-(triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, i.e., a bis(triethoxysilylpropyl)amine.

It was found that particularly stable and uniform films could be obtained on the keratinous material even when the agent contained two structurally different organic silicon compounds, each containing one to three silicon atoms.
In a preferred embodiment, an agent exemplified in that it comprises at least one organic silicone compound of formula (I) and at least one organic silicone compound of formula (IV).
In an explicitly very particularly preferred embodiment, an agent exemplified in that it contains at least one organic silicone compound of formula (I) selected from the group including (3-aminopropyl)triethoxysilane and (3-aminopropyl)trimethoxysilane, and additionally containing at least one organic silicone compound of formula (IV) selected from the group including methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, propyltriethoxysilane, hexyltrimethoxysilane and hexyltriethoxysilane.
In another preferred embodiment, an agent is exemplified in that the agent—contains, based on the total weight of the agent—:
From about 0.5 to about 5 weight % of at least one first organic silicon compound selected from the group of (3-aminopropyl)trimethoxysilane, (3-aminopropyl)triethoxysilane, (2-aminoethyl)trimethoxysilane, (2-aminoethyl)triethoxysilane, (3-dimethylaminopropyl)trimethoxysilane, (3-dimethylaminopropyl)triethoxysilane (2-dimethylaminoethyl)trimethoxysilane and (2-dimethylaminoethyl)triethoxysilane, and

Even the addition of small amounts of water leads to hydrolysis in organic silicon compounds with at least one hydrolyzable group. The hydrolysis products and/or organic silicon compounds having at least one hydroxy group may react with each other in a condensation reaction. For this reason, both the organosilicon compounds having at least one hydrolyzable group and their hydrolysis and/or condensation products may be present in the composition. When organosilicon compounds having at least one hydroxyl group are used, both the organic silicon compounds having at least one hydroxyl group and their condensation products may be present in the composition.
A condensation product is understood to be a product formed by the reaction of at least two organic silicon compounds each having at least one hydroxyl group or hydrolyzable group per molecule with elimination of water and/or with elimination of an alkanol. The condensation products can be, for example, dimers, but also trimers or oligomers, with the condensation products being in equilibrium with the monomers. Depending on the amount of water used or consumed in the hydrolysis, the equilibrium shifts from monomeric organic silicon compounds to condensation product.
In the context of the present disclosure, figures in wt.-% are—unless otherwise stated—always based on the total weight of the cosmetic product.
According to the present disclosure, the cosmetic agent is a fluid. In the present case, a fluid is to be understood as a non-gaseous, flowable mass. The fluid contains the multivalent metal cation, in particular the divalent metal cation, in a certain molar concentration.
As a second ingredient essential to the disclosure, the cosmetic composition for treating a keratinous material contains a polyvalent metal cation, in particular a divalent metal cation. In the course of the work leading to the present disclosure, it has become apparent that, to solve the problem underlying the disclosure, it is particularly advantageous if the organic silicon compound, for example 3-(triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, i.e., a bis(triethoxysilylpropyl)amine, is combined with a polyvalent, in divalent metal cation.
It was found that the combination of bis(triethoxysilylpropyl)amine with polyvalent metal cations protects hair from washing out artificial hair dyes. Likewise, especially in oxidatively damaged hair, the hair surface becomes more hydrophobic and the denaturation temperature, hair swelling, and tensile-elongation parameters are improved or advantageously changed. By improving these parameters, the physical properties of damaged hair are brought back to the level of undamaged hair, indicating that the hair structure has been restabilized.
