The present disclosure relates to cosmetic products for treatment of a keratinous material, wherein the product comprises an organic silicon compound as a first component and an acid as a second component, as well as the use of the cosmetic product.
External stressing of the hair due to chemical materials from a variety of different sources poses challenges for the development of cosmetic care products. Air and water pollution adversely affect skin and hair. The most important air pollutants include polycyclic aromatic hydrocarbons, volatile organic compounds, nitrogen oxide (NOx), particles and cigarette smoke. The presence of other air pollutants and to UV radiation can reinforce the effect of various air pollutants.
It is known that the toxicity of gaseous pollutants of the air, such as sulfur dioxide, ozone and nitrogen oxides, especially depends on their initiator activity for free radicals, which causes damages in living beings. Free radicals are metabolic products that also occur naturally in the body. In large quantities, free radicals can pander to irritations and inflammations and accelerate the aging process. Such cases are referred to as oxidative damage. Free radicals can also cause hair damage, evinced, for example, by a reduction in the shine as well as of the grip and/or fading of the hair color.
Furthermore, frequently changing customer requests regarding a certain finish of the hair are linked to a recurrent chemical stress on the hair.
Organic compounds of silica from the group of silanes are described in the state of the art, which comprise at least one hydroxy group and/or hydrolysable group. Due to the presence of hydroxy groups and/or hydrolysable groups, silanes are reactive substances that hydrolyze or oligomerize or polymerize in the presence of water. When using on a keratinous material, oligomerization or polymerization of the silanes initiated by the presence of water eventually causes the formation of a film that can provide protection.
Cosmetic products for the treatment of a keratinous material are provided herein. In an embodiment, a cosmetic product includes
a) at least one organic silicon compound and
b) organic and/or inorganic acid with a pKS value of from about −6 to about 5.
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 objective forming the basis of the present disclosure includes providing a product with an improved care and/or protective properties. In particular, the objective underlying the present disclosure was to provide a cosmetic product that improves the effect of the organic silicon compound used.
This objective is achieved by employing a cosmetic product for treating a keratinous material, comprising
a) at least one organic silicon compound and
b) an organic and/or inorganic acid with a pKs value of about −6 to about 5.
Keratinous material includes hair, skin, 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 be human hair, human skin and human nails, especially fingernails and toenails. Especially preferably, keratinous material is understood to be human hair in particular.
As the first ingredient essential to the invention, the cosmetic product for the treatment of a keratinous material contains at least one organic silicon compound. Preferred organic silicon compounds are selected from silanes with one, two or three silicon atoms, where 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.
Composition (a) contains at least one organic silicon compound 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.
As part of a particularly preferred embodiment, the product for the treatment of a keratinous material features at least one organic silicon compound, selected from silanes having one, two or three silicon atoms, the organic silicon compound further comprising 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′″SiO—CH2—CH3. The radicals R′, R″ and R′″ represent the three remaining free valences of the silicon atom.
Particularly good results could be obtained if the product for the treatment of 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 from the negative effects of water and/or air pollutants (“Anti-pollution” effect) and the best care of stressed hair could be obtained, if the composition for the treatment of a keratinous material contains at least one organic silicon compound of the formula (I), in which the radicals R3, R4 independently represent a methyl group or an ethyl group.
Especially well-suited organic silicon compounds of the formula (I) are:
The aforementioned organic silicon compound of formula (I) is commercially available.

In a further embodiment, the product for the treatment of a keratinous material contains 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 carry the silicon-containing groups (R5O)c(R6)dSi— and —Si(R6′)d′(OR5′)c at both ends.
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 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.

If c and c′ are both the number 3 and d and d′ are both the number 0, the organic silicon compound of the present disclosure corresponds to formula (IIa)
(R5O)3Si-(A)e-[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)e- and —[NR7-(A′)]f- and —[O-(A″)]g- and —[NR8-(A′″)]h- are located in the middle part of the organic silicon compound of formula (II).
In this context, the presence of certain groupings has proved to be particularly beneficial in terms of increasing the ‘anti-pollution’ effect. Particularly good results were obtained when at least two of the radicals 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.
If e and f both stand for the number 1 and g and h both stand for the number 0, the organic silicon compounds correspond to formula (IIb)

In particular, the radicals A, A′, A″, A′″ and A″″ stand for a propylene group (—CH2—CH2—CH2—).
If the radical f represents the number 1, then the organic silicon compound of formula (II) contains a structural grouping —[NR7-(A′)]-.
If the radical h represents the number 1, then the organic silicon compound of formula (II) contains a structural grouping —[NR8-(A′″)]-.
Herein, the radicals 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 grouping of the formula (III)

In a further preferred embodiment, product is exemplified in that the it contains at least one organic silicon compound of formula (I) and at least one organic silicon compound of formula (IV).
In an explicitly specifically preferred embodiment, a product is exemplified in that it contains at least one organic silicon compound of the formula (I), which is selected from the group of (3-Aminopropyl)triethoxysilane and (3-Aminopropyl)trimethoxysilane, and additionally contains at least one organic silicon compound of the formula (IV), which is selected from the group of methyltrimethoxysilane, methyltriethoxysilane, ethyltrimethoxysilane, ethyltriethoxysilane, propyltrimethoxysilane, propyltriethoxysilane, hexyltrimethoxysilane and hexyltriethoxysilane.

In the case of organic silicon components with at least one hydrolysable group, the addition of small quantities of water already leads to hydrolysis. The hydrolysis products and/or organic silicon compounds with at least one hydroxy group can react with each other in a condensation reaction.

As the second important component essential for the invention, the cosmetic product for treatment of a keratinous material contains, as a further component b) an organic and/or inorganic acid with a pKS value of from about −6 to about 5. In the course of the work leading to this invention, it was observed that for achieving a particularly good care effect, it is especially advantageous, if the organic silicon compounds, for example (3-aminopropyl)triethoxysilane, i.e. an aminopropyl triethoxysilane (AMEO), or for example 3-(triethoxysilyl)-N-[3-(triethoxysilyl)propyl]-1-propanamine, i.e. a Bis(triethoxysilylpropyl) amine, is combined with an organic and/or inorganic acid with a pKS value of from about −6 to about 5. In particular, it is seen that on addition of an acid with a pKS value from about −6 to about 5, the film formation completes sooner and the retained films have a finer structure.

An acidic cosmetic composition comprising the said silanes, which cover the hair surface, is particularly effective in achieving the task underlying the invention. According to the preferred embodiments, the pH value of the cosmetic product lies in the range from about 1.5 to about 8, preferably from about 2 to about 7, more preferred from about 2.5 to about 6, most preferred from about 3 to about 5.

Waxes are used alternatively or additionally as solidifying compounds. Ideally, the polymers and/or waxes when used on the keratinous material leave a polymer film that lends a strong hold to the hairstyle on the one hand, is however sufficiently flexible on the other, so that it does not break on being stressed.
The synthetic polymers can be divided in cationic, anionic, anionic and amphoteric solidifying polymers.
