The present disclosure relates to cosmetic compositions for treating a keratinous material, the composition comprising as a first component an organic silicon compound and as a second component at least one cationic polymer, and to the use of the cosmetic composition.
The external exposure of hair to chemicals from a variety of different sources poses challenges for the development of cosmetic care 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.
It is known that the toxicity of gaseous pollutants in the air, such as sulfur dioxide, ozone, and nitrogen oxides, is related to their initiator activity for free radicals, which cause damage to living organisms. Free radicals are metabolic products that also occur naturally in the body. In large quantities, free radicals can promote irritation and inflammation and accelerate the process of aging. In this case, the term “oxidative damage” is used. Free radicals can also cause hair damage, which is visible, for example, as a reduction in shine as well as grip and/or fading of hair color.
Furthermore, often changing consumer demands for a certain hair texture are associated with recurring chemical exposure of the hair. For example, hair coloring stresses the hair, due to which a special, intensive care may be necessary.
In the prior art, organosilicon compounds from the group of silanes comprising at least one hydroxy group and/or hydrolysable group are described. Due to the presence of the hydroxy groups and/or hydrolysable groups, the silanes are reactive substances that hydrolyze or oligomerize or polymerize in the presence of water. The oligomerization or polymerization of the silanes initiated by the presence of the water, when applied to a keratinous material, ultimately leads to the formation of a film that can exert a protective effect.
Cosmetic compositions for treating keratinous materials, and methods of using the same, are provided. In an exemplary embodiment, a cosmetic composition for treating keratinous materials includes at least one organic silicon compound and at least one cationic polymer.
A method of using a cosmetic composition for treating keratinous materials is provided in another embodiment. The method includes applying the cosmetic composition to the keratinous materials, where the cosmetic composition includes an organic silicon compound and a cationic polymer.
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 agent which, after a hair treatment, enables a caring after-treatment which provides special care to stressed hair.
This task is solved by a cosmetic agent for the treatment of a keratinous material, comprising
a) at least one organic silicon compound and
b) at least one cationic polymer.
By a keratinous material is meant hair, the skin, and 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 composition described herein, the cosmetic composition for treating a keratinous material contains at least one organic silicon compound. 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 hydrolysable 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 hydrolysable 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 hydrolysable 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 hydrolysable group(s) is (are) preferably a C1-C6 alkoxy group, especially an ethoxy group or a methoxy group. It is preferred when the hydrolysable group is directly bonded to the silicon atom. For example, if the hydrolysable 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 propylene group (—CH2—CH2—CH2—) is particularly preferred. From a chain length of 3 C atoms, divalent alkylene groups can also be branched. Examples of branched divalent C3-C20 alkylene groups are (—CH2—CH(CH3)—) and (—CH2—CH(CH3)—CH2—).
In the organic silicon compounds of the formula (I)
R1R2N-L-Si(OR3)a(R4)b (I),
the radicals R1 and R2 independently of one another represent a hydrogen atom or a C1-C6 alkyl group. In particular, the radicals R1 and R2 both represent a hydrogen atom.
In the middle part of the organic silicon compound is the structural unit or the linker -L- which stands for a linear or branched, divalent C1-C20 alkylene group.
Preferably, -L- represents a linear, divalent C1-C20 alkylene group. Further preferably, -L- represents a linear divalent C1-C6 alkylene group. Particularly preferred -L stands for a methylene group (—CH2—), an ethylene group (—CH2—CH2—), a propylene group (—CH2—CH2—CH2—) or a butylene (—CH2—CH2—CH2—CH2—). L very particularly stands for a propylene group (—CH2—CH2—CH2—).
The organic silicon compounds of formula (I)
R1R2N-L-Si(OR3)a(R4)b (I),
carry the silicon-containing grouping —Si(OR3)a(R4)b at one end.
In the terminal structural unit —Si(OR3)a(R4)b, R3 is hydrogen or a C1-C6 alkyl group, and R4 is a C1-C6 alkyl group. R3 and R4 particularly preferably independently of each other represent a methyl group or an ethyl group.
Here a stands for an integer from 1 to 3, and b stands for the integer 3-a. If a stands for the number 3, then b is equal to 0. If a stands for the number 2, then b is equal to 1. If a stands for the number 1, then b is equal to 2.
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)e-[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′)a′(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 0 or 1, with the proviso that at least one of the radicals e, f, g, and h is different from 0. In other words, an organic silicon compound of formula (II) contains at least one grouping selected from the group of -(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 d stands for an integer from 1 to 3, and d stands for the integer 3-c. If c stands for the number 3, then d is equal to 0. If c stands for the number 2, then d is equal to 1. If c stands for the number 1, then d is equal to 2.
Analogously c′ stands for a whole number from 1 to 3, and d′ stands for the whole number 3-c′. If c′ stands for the number 3, then d′ is 0. If c′ stands for the number 2, then d′ is 1. If c′ stands for the number 1, then d′ is 2.
An extremely high anti-pollution effect of the agent for the treatment of a keratinous material could be obtained when the residues c and c′ both stand for the number 3. In this case d and d′ both stand for the number 0.
In another preferred embodiment, the agent for treating a keratinous material comprises at least one organic silicon compound of formula (II)
(R5O)c(R6)dSi-(A)e-[NR7-(A′)]f-[O-(A″)]g-[NR8-(A′″)]h-Si(R6′)d′(OR5′)c′ (II),
where
R5 and R5′ independently represent a methyl group or an ethyl group,
c and c′ both stand for the number 3 and
d and d′ both stand for the number 0.
When c and c′ both represent the number 3 and d and d′ both represent the number 0, the organic silicon compounds correspond to formula (IIa)
(R5O)3Si-(A)c-[NR7-(A′)]f-[O-(A″)]g—[NR8-(A′″)]h-Si(OR5′)3 (IIa).
The radicals e, f, g, and h can independently stand for the number 0 or 1, whereby at least one radical from e, f, g, and h is different from zero. The abbreviations e, f, g, and h thus define which of the groupings -(A)c- 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 1. Especially preferred e and f both stand for the number 1. Furthermore, g and h both stand for the number 0.
When e and f are both 1 and g and h are both 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 divalent C1-C20 alkylene group. Preferably the radicals A, A′, A″, A′″ and A″″ independently of one another represent a linear, divalent C1-C20 alkylene group. Further preferably the radicals A, A′, A″, A′″ and A″″ independently represent a linear divalent 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 1, the organic silicon compound of formula (II) contains a structural grouping —[NR7-(A′)]-.
When the radical h represents the number 1, the organic silicon compound of formula (II) contains a structural grouping —[NR8-(A″)]-.
Wherein R7 and R8 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 1 and the radical h represents the number 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 3 reactive silane groups.
In another preferred embodiment, the agent for treating a keratinous material comprises at least one organic silicon compound of formula (II)

It has also been found to be advantageous when the agent for treating a keratinous material applied to the hair contains at least one organic silicon compound of formula (IV)
R9Si(OR10)k(R11)m (IV).
The compounds of formula (IV) 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 organic silicon compound(s) of formula (IV) may also be referred to as silanes of the alkylalkoxysilane or alkylhydroxysilane type,

R10 represents a hydrogen atom or a C1-C6 alkyl group,
R11 represents a C1-C6 alkyl group
k is an integer from 1 to 3, and

In another preferred embodiment, the composition for treating a keratinous material contains, in addition to the organic silicon compounds of the formula (I) and (II), at least one further organic silicon compound of the formula (IV)

In the organic silicon compounds of formula (IV), the radical R9 represents a C1-C12 alkyl group. This C1-C12 alkyl group is saturated and can be linear or branched.

An extremely high “anti-pollution” effect could be obtained if the agent for treating a keratinous material contains at least one organic silicon compound of formula (IV) in which the radical k represents the number 3. In this case the residue m stands for the number 0.
Organic silicon compounds of the formula (IV) that are particularly suitable for solving the problem are
and propyltrimethoxysilane, propyltriethoxysilane, octadecyltrimethoxysilane and/or octadecyltriethoxysilane.
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 an 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.
According to preferred embodiments of the present disclosure, the organic silicon compound of formula (I), in particular the (3-aminopropyl)triethoxysilane, is present in an amount of from about 0.01 to about 10% by weight, preferably from about 0.02 to about 8% by weight, more preferably from about 0.05 to about 6% by weight, most preferably from about 0.1 to about 4% by weight, based on the total weight of the cosmetic product, in the cosmetic product, and/or the organic silicon compound of the formula (II), in particular the 3-(triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, is present in an amount of from about 0.01 to about 10% by weight, preferably from about 0.02 to about 9% by weight, more preferably from about 0.05 to about 8% by weight, most preferably from about 0.1 to about 7%, by weight, based on the total weight of the cosmetic composition, in the cosmetic composition.
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.
In a preferred embodiment, an exemplary agent 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 of (3-aminopropyl)triethoxysilane and (3-aminopropyl)trimethoxysilane, and additionally contains at least one organic silicone compound of formula (IV) selected from the group of 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% by 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
from about 3.2 to about 10% by weight of at least one second organic silicon compound selected from the group of methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, propyltriethoxysilane, hexyltrimethoxysilane, hexyltriethoxysilane, octyltrimethoxysilane, octyltriethoxysilane, dodecyltrimethoxysilane, dodecyltriethoxysilane, octyldecyltrimethoxysilane and octyldecyltriethoxysilane.
Even the addition of small amounts of water leads to hydrolysis in organic silicon compounds with at least one hydrolysable 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 hydrolysable 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 hydrolysable 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.
As a second ingredient essential to the composition described herein, the cosmetic composition for treating a keratinous material contains, as a further component b), at least one cationic polymer. In the course of the work leading to the present disclosure, it has been found that, to achieve a particularly good care effect, it is especially advantageous if the organic silicon compounds, for example (3-aminopropyl)triethoxysilane, i. e. (3-aminopropyl)triethoxysilane, i.e., an aminopropyltriethoxysilane (AMEO), or for example 3-(triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, i.e., a bis(triethoxysilylpropyl)amine, is combined with at least one cationic polymer.
The term cationic polymer refers to a polymer that has a cationic formal charge. This may be located along the backbone of the polymer or may be present in a side group. The cationic formal charge can also result from protonation in an acidic environment. The term “polymer” has the ordinary meaning known to those skilled in the art.
It was found that the combination of the cationic polymer on the one hand and the organosilicon compound, aminopropyltriethoxysilane (AMEO) and/or bis(triethoxysilylpropyl)amine, on the other hand, is particularly powerful in terms of a conditioning aftertreatment. The combination of a cationic polymer and said silanes occupying the hair surface is particularly effective in solving the problem underlying the present disclosure. The hair surface is hydrophobized, reducing frizz. The hair becomes softer, especially in the case of a previously exerted high chemical stress.
