Description

"Antiperspirant Cosmetics with Aromatic Sulfonic Acids"

The present invention relates to an antiperspirant cosmetic agent which contains at least one antiperspirant aluminum salt and at least one optionally functionalized aromatic sulfonic acid and wherein the addition of the at least one optionally functionalized aromatic sulfonic acid results in activation of the at least one antiperspirant aluminum salt and in a stabilization of this activated state.

Furthermore, the present invention relates to the use of a combination of at least one antiperspirant aluminum salt and at least one optionally functionalized aromatic sulfonic acid for reducing and / or preventing underarm perspiration.

Moreover, the present invention relates to a non-therapeutic cosmetic method for preventing and / or reducing transpiration of the body, in which the antiperspirant according to the invention is applied to the skin, in particular to the skin of the armpits.

Finally, the present invention relates to the use of an optionally functionalized aromatic sulfonic acid for activating and / or stabilizing an antiperspirant aluminum salt.

Washing, cleansing and caring for one's own body is a basic human need, and modern industry is constantly trying to meet these needs of man in a variety of ways. Especially important for daily hygiene is the permanent elimination or at least reduction of body odor and underarm wetness. Numerous specific deodorant or antiperspirant personal care products are known in the art which have been developed for use in body regions having a high density of sweat glands, especially in the underarm area. These are formulated in a wide variety of dosage forms, for example as powder, in stick form, as aerosol spray, pump spray, liquid and gel roll on application, cream, gel and as impregnated flexible substrates (towels).

Prior art cosmetic antiperspirants contain at least one antiperspirant salt in addition to at least one oil or fatty substance and one perfume component or perfume.

As an antiperspirant salt usually basic aluminum and aluminum zirconium halides are used in the form of chlorides, as they differ from the non-basic Aluminum and aluminum zirconium chlorides have no irritating effect on the skin. However, the disadvantage of the basic aluminum and aluminum zirconium halides is the formation of higher molecular weight oligomeric and polymeric aluminum species which significantly reduce the effectiveness of the basic aluminum and aluminum zirconium salts in antiperspirants.

For this reason, attempts have been made in the prior art to increase the activity of the basic aluminum and aluminum zirconium halides by activation, while at the same time maintaining good skin tolerance. Thus, EP 0 308 937 A2, EP 0 183 171 A2, US Pat. No. 4,359,456 A and EP 0 191 628 A2 describe basic aluminum and aluminum zirconium halides, in particular aluminum chlorides, which have been obtained by a thermal treatment. The heat-treated activated basic aluminum and aluminum zirconium halides have a lower content of high molecular weight species in gel permeation chromatography (GPC) compared to untreated basic aluminum and aluminum zirconium halides and thus enhanced antiperspirant efficacy against antiperspirants.

Furthermore, the effectiveness of basic aluminum and aluminum zirconium halides can be increased by incorporating organic acids as complexing ligands. Thus, US 3,542,919 A, US 3,553,316 A, US 3,991,176 A and WO 2005/092795 A1 disclose processes for producing such stabilized aluminum and aluminum zirconium halides, which have a higher proportion of short-chain species and in activated form.

A disadvantage of the aforementioned activated basic aluminum and aluminum zirconium halides of the prior art is the decrease in the antiperspirant effect with increasing storage time and / or when using protic solvents. This is due to the fact that the polymer distribution of the aluminum species is based on a reversible equilibrium and shifts this equilibrium in protic solvents with increasing time to higher molecular weight and thus less effective aluminum species.

There is therefore a need for antiperspirant cosmetic products which, even during long storage periods and / or when using high amounts of protic solvents, have no shift in the polymer distribution to long-chain polymers and thus no significant decrease in the antiperspirant effect. Furthermore, the antiperspirants should be inexpensive to produce.

It is an object of the present invention to provide an antiperspirant cosmetic agent which avoids or at least mitigates the disadvantages of the prior art and in which there is no significant decrease in the activation of antiperspirant agents Aluminum salts during longer storage periods and / or in the presence of protic solvents occurs.

It has now surprisingly been found that the use of special, optionally functionalized aromatic sulfonic acids or their salts in cosmetic compositions containing antiperspirant aluminum salts, to an increased formation of short-chain aluminum species and to stabilize these short-chain aluminum species even over long Storage periods leads.

The subject of the present invention is thus an antiperspirant cosmetic containing

a) at least one substance selected from the group of cosmetic oils which are liquid at 20 ° C. and 1 .013 hPa, fragrances and waxes,

b) at least one antiperspirant aluminum salt in a total amount of 1 to 80 wt .-%, based on the total weight of the antiperspirant cosmetic agent, and

R ¹ , R ² and R ³ each independently represent hydrogen, a linear or branched alkyl group of 1 to 10 carbon atoms, -OH, -NH ₂ , -COOB ⁺ , or -SCb ^" B ⁺ , and

x stands for integers from 0 to 4.

By combining antiperspirant aluminum salts with specific aromatic sulfonic acids of the formula (AS-I), without limiting themselves to this theory, an increase in the proportion of short-chain species of the antiperspirant aluminum salts is achieved. Furthermore, the thus formed short-chain species are excellently stabilized by the aforementioned aromatic sulfonic acids, so that an improved antiperspirant effect is ensured over a long period of time. By using the special In particular, antiperspirants with a high content of protic solvents, which despite the high amounts of protic solvents have an excellent antiperspirant effect even during prolonged storage periods, can be prepared with aromatic sulfonic acids.

Furthermore, when using the weight ratio mentioned above, protic solvents, in particular in high concentrations or amounts, can be used without the antiperspirant effect of the antiperspirant cosmetic agents according to the invention being adversely affected, so that an extremely flexible formulation of the compositions according to the invention is possible.

According to another embodiment of the present invention, the antiperspirant cosmetic agent contains no zirconium-containing compounds. The inventive avoidance of the use of zirconium-containing antiperspirant compounds, such as zirconium-aluminum mixed salts results in the more cost-effective provision of the antiperspirant cosmetic agents of the invention, since the raw materials for the production of zirconium-containing compounds have higher prices.

Furthermore, a third aspect of the present invention is a non-therapeutic cosmetic method for preventing and / or reducing transpiration of the body, which comprises an antiperspirant cosmetic agent containing at least one selected from the group of cosmetic oils at 20 ° C and 1,013 hPa liquid, fragrances and waxes, at least one antiperspirant aluminum salt in a total amount of 1 to 80 wt .-%, based on the total weight of the antiperspirant cosmetic agent, and at least one compound of formula (AS-I), on the skin , in particular on the skin of the armpits, is applied. With regard to the method according to the invention, mutatis mutandis applies to the said antiperspirant cosmetic agents according to the invention and the use according to the invention.

Finally, a fourth subject of the present invention is the use of at least one compound of the formula (AS-I)

R ¹ , R ² and R ³ each independently represent hydrogen, a linear or branched alkyl group of 1 to 10 carbon atoms, -OH, -NH ₂ , -COOB ⁺ or -SO 3 ^" B ⁺ , and x stands for integers from 0 to 4,

for activating and / or stabilizing at least one antiperspirant aluminum salt.

For the purposes of the present invention, activation means the increased formation of short-chain polymers of the antiperspirant aluminum salt when the compound of the formula (AS-I) is used.

Furthermore, stabilization in the sense of the present invention is to be understood as meaning the avoidance or significant slowing down of the renewed formation of higher-chain polymers from the short-chain polymers of the antiperspirant aluminum salts formed during the activation.

By using special aromatic sulfonic acids of the formula (AS-I) it has surprisingly been possible to increase the activity of antiperspirant aluminum salts even over a longer storage period. Without wishing to be limited to this theory, the use of compounds of the formula (AS-I) achieves an increase in the proportion of short-chain species of the antiperspirant aluminum salts. Furthermore, the thus formed short-chain species are excellently stabilized by the aforementioned aromatic sulfonic acids, so that an improved antiperspirant effect is ensured over a long period of time.

A particularly good activation and / or stabilization of the at least one antiperspirant aluminum salt is achieved if the compound of the formula (AS-I) is used in a total amount of from 0.01 to 50% by weight, preferably from 0.1 to 40% by weight. %, preferably from 0.5 to 30 wt .-%, more preferably from 1 to 20 wt .-%, even more preferably from 1, 5 to 10 wt .-%, in particular from 2 to 7 wt .-%, based on the total weight of the compound of formula (AS-I), the at least one antiperspirant aluminum salt and optionally other ingredients is used. The abovementioned amounts lead to a particularly good activation and stabilization of the antiperspirant aluminum salt even over longer storage periods.

In this context, it is advantageous if the antiperspirant aluminum salt in a total amount of 1 to 99.99 wt .-%, preferably from 2 to 80 wt .-%, preferably from 3 to 60 wt .-%, more preferably from 4 to 50 wt .-%, in particular from 6 to 45 wt .-%, based on the total weight of the compound of formula (AS-I), the at least one antiperspirant aluminum salt and optionally further ingredients is used.

It has proven to be particularly advantageous for the activation and / or stabilization of the at least one antiperspirant aluminum salt if a weight ratio of the antiperspirant aluminum salt to the compound of the formula (AS-I) is from 5,000: 1 to 1: 0.16, preferably from 1000: 1 to 1: 1, preferably from 100: 1 to 1: 5, more preferably from 50: 1 to 1:10, even more preferably from 10: 1 to 1:30, in particular from 4: 1 to 1 : 50, is used. The above-mentioned weight ratio refers to the total amount of all antiperspirant aluminum salts and all compounds of formula (AS-I) in the antiperspirant cosmetic agent.

Surprisingly, when using the compound of formula (AS-I), even in the presence of high amounts of protic solvents, such as water, a significantly increased activation and / or stabilization of the antiperspirant aluminum salt results. Therefore, it is preferable that a total amount of free water is from 1 to 90% by weight, preferably from 5 to 80% by weight, preferably from 10 to 70% by weight, more preferably from 12 to 60% by weight. , in particular from 15 to 55 wt .-%, based on the total weight of the compound of formula (AS-I), the at least one antiperspirant aluminum salt, the free water and optionally other ingredients is used.

Furthermore, it is also possible within the scope of the present invention to dry the liquid mixture resulting from the activation and stabilization of the at least one antiperspirant aluminum salt by the compound of the formula (AS-I). The drying of this mixture can be carried out, for example, by means of conventional drying methods, such as spray drying. The powders obtained in this way are excellent storage and have a long shelf life.

With regard to further preferred embodiments, what has been said about the cosmetic antiperspirant agents according to the invention applies mutatis mutandis.

The following examples illustrate the present invention without, however, limiting it to: Examples:

1. HPLC measurements:

To determine the activation of the antiperspirant aluminum salt in the antiperspirant cosmetic agent, the following aqueous solutions are prepared and stored for 4 weeks at room temperature (in% by weight):

* Active ingredient

inventively Such solutions are, inter alia, representative of hydrous antiperspirant emulsions (antiperspirant rollons, antiperspirant sticks, antiperspirant gels, antiperspirant pump sprayers).

After 4 weeks, the activation resulting directly from the polymer distribution of samples V-I and El is determined by size-exclusion chromatography (also called "size exclusion chromatography" or SEC.) For this, the respective sample is first adjusted to the concentration of 1 g of ACH / 25 ml of water are diluted and filtered (0.2 μm filter) .The respective sample is then measured using SEC using a commercially available HPLC system with a refractive index detector, the following parameters being used: flow: 1 ml / min

Temperature: 23 ° C

Eluent: 0.02M HCl

Column: 6.2 x 250 mm, column material: silanized porous silica microspheres (5 μητι).

For each sample, 12 or more peaks are obtained, with the lower retention time peaks for the ACH long chain polymers, the higher retention time peaks for shorter chain length ACH polymers. The peaks obtained for each sample in the chromatogram are integrated, with peaks 2 and 3 (long chain polymers), 4 to 8 (medium chain polymers), 9 to 1 1 (short chain polymers) and 12, and all subsequent peaks (very high) short chain length of the polymers) due to shoulders are integrated together. In the table below, the area fraction of peaks 1 to 8 (long and medium chain length polymers) and the area fraction of peaks 9 to 12 and more (short and very short chain length polymers) in the total area of all the samples obtained in the chromatogram Peaks indicated:

The formula E-1 according to the invention has a higher proportion of short-chain polymers (peaks 9 to 12 or more), ie. H. a better activation and stabilization, than the Comparative Example V-l. Consequently, the addition of 5-sulfosalicylic acid results in improved activation and stabilization of the aluminum salt used.
