Description

Application Field and State of the Art

The invention relates to a cosmetic antiperspirant composition as well as a cosmetic product.

Antiperspirants are generally understood to be substances that reduce the activity of sweat glands and the amount of sweat produced, thereby indirectly reducing body odor.

The mechanism of action of conventional antiperspirant formulations is based on the presence of aluminum salts, such as aluminum chlorohydrate, as active antiperspirant agents. The aluminum salts act as astringents and denaturants. Due to their astringent effect, the sweat ducts constrict. Because of their denaturing effect, the sweat proteins precipitate and form a protein plug at the outer end of the sweat ducts of the sweat glands, thereby reducing the overall amount of sweat that can escape.

Corresponding antiperspirant compositions are known, for example, from the printed publications DE 10 2011 086 019 A1, DE 10 2007 063 352 A1, EP 2 481 392 A2, WO 2001/047476 A2, WO 2003/041674 A1, WO 2005/112879 A1 and WO 2006/066704 A1.

From U.S. Patent 4,089,942, a deodorizing composition is known. The composition may contain ethanol as well as weak organic acids, such as tartaric acid.

A disadvantage of conventional antiperspirant formulations is that the aluminum salts they contain are suspected of causing permanent damage in the human body. Aluminum salts are suspected of triggering breast cancer or Alzheimer's disease.

Although scientific evidence definitively supporting health impairments caused by aluminum-containing cosmetics is not yet available, there is a need for antiperspirant formulations that do not raise medical concerns.

Task and Solution

Therefore, the present invention was based on the object of providing a cosmetic antiperspirant composition as well as a cosmetic product that address the aforementioned needs and avoid the disadvantages known from the prior art.

This task is solved by a cosmetic antiperspirant composition having the features of claim 1, as well as by a cosmetic product according to claim 10. Preferred embodiments are defined in dependent claims 2 to 9. The wording of all claims is hereby incorporated by explicit reference into the content of the present description.

According to a first aspect, the invention relates to a cosmetic antiperspirant composition, i.e., a perspiration- or sweat-inhibiting composition, which contains at least one antiperspirant active ingredient selected from the group consisting of tartaric acid, tartaric acid salts, and mixtures thereof.

The present invention is based on the surprising finding that the hydroxy carboxylic acids or hydroxy carboxylic acid salts, which will be explained in more detail below, are suitable for substituting aluminum salts contained in conventional antiperspirant formulations.

The cosmetic antiperspirant composition advantageously reduces in particular the activity of apocrine sweat glands, which are located especially in the area of the axilla (pyramidal anatomical space between the lateral chest wall and the medial upper arm), the areola, the groin area, the perianal region (circular anal glands), and the pubic region (in women: mons pubis, labia majora; in men: scrotum).

The term "hydroxy carboxylic acid" can, in the sense of the present invention, mean either a single type of hydroxy carboxylic acid or several different types of hydroxy carboxylic acids. Similarly, the term "hydroxy carboxylic acid salt" can, in the sense of the present invention, mean either a single type of hydroxy carboxylic acid salt or several different types of hydroxy carboxylic acid salts.

The following statements regarding the hydroxy carboxylic acid are accordingly also applicable to the hydroxy carboxylic acid salt.

In a preferred embodiment, the cosmetic antiperspirant composition is free from zirconium salts. In other words, it is preferred according to the invention that the cosmetic antiperspirant composition is zirconium salt-free.

According to a further embodiment, the cosmetic antiperspirant composition is free from aluminum, zirconium, and optionally zinc salts.

The antiperspirant composition is aluminum salt-free, that is, free from aluminum salts. In other words, the antiperspirant composition according to the invention is an aluminum salt-free cosmetic antiperspirant composition. The term "aluminum salt" generally refers to aluminum-containing salts within the meaning of the present invention and thus includes both inorganic and organic salts of aluminum, such as aluminum chlorohydrate and aluminum hydroxyacetates, as well as mixed salts of aluminum with other elements, such as zirconium.

In a further embodiment, the antiperspirant composition is free from aluminum compounds. In other words, the antiperspirant composition according to the invention can preferably be an aluminum-free cosmetic antiperspirant composition. The term "aluminum compounds" generally refers in the context of the present invention to compounds of the chemical element aluminum. According to the present invention, the term "aluminum compounds" thus includes not only aluminum salts, but in particular also aluminum-containing complex compounds, such as, for example, an aluminum-zirconium tetrachlorohydrex-glycine complex.

In a further embodiment, the antiperspirant composition, in addition to the at least one antiperspirant active ingredient provided according to the invention, does not contain any additional antiperspirant active ingredient.

At least one antiperspirant active ingredient is selected from the group consisting of tartaric acid, its salts, and mixtures thereof. In other words, the at least one antiperspirant active ingredient is tartaric acid, its salts, and/or mixtures thereof.

According to the invention, it can still be preferred if the cosmetic antiperspirant composition contains only tartaric acid, citric acid, malic acid, gallic acid, their salts and/or mixtures thereof as the antiperspirant active ingredient(s).

According to the invention, the at least one antiperspirant active ingredient is tartaric acid or a tartaric acid salt. The advantages explained according to the invention are particularly evident in the case of tartaric acid or a tartaric acid salt.

The at least one antiperspirant active ingredient constitutes from 2.5 to 40 weight percent, preferably from 3 to 35 weight percent, more preferably from 5 to 30 weight percent, particularly preferably from 8 to 25 weight percent, and most preferably from 10 to 20 weight percent, based on the total weight of the composition. The invention is further based on the surprising finding that the denaturing properties of the at least one antiperspirant active ingredient according to the invention are particularly pronounced at the concentrations mentioned in this paragraph. A further advantageous effect of the antiperspirant active ingredient proportions described in this paragraph is that the addition of preservatives becomes unnecessary.

Tartaric acid can be present in a form selected from the group consisting of D-(-)-tartaric acid, L-(+)-tartaric acid, meso-tartaric acid, their salts, and mixtures thereof. In particular, the tartaric acid can be present in the form of a racemic mixture of D-(-)-tartaric acid (or a salt thereof) and L-(+)-tartaric acid (or a salt thereof).

The cosmetic antiperspirant composition further contains at least one carrier fluid. The term "carrier fluid" is understood in the sense of the present invention to mean a liquid carrier material, particularly a dispersion, solution or suspension medium. The carrier fluid is ethanol and may additionally be selected from the group consisting of isopropanol, 2-methylpropanol-2, water, and mixtures thereof.

The use of ethanol as a carrier fluid is particularly advantageous because ethanol has a strong denaturing effect on protein building blocks, especially at higher concentrations. This allows the sweat-inhibiting properties of the composition according to the invention to be further enhanced. Moreover, ethanol exhibits antibacterial effects, particularly at higher concentrations, thereby enabling bacteria present on the skin that decompose sweat and are causally responsible for body or sweat odor to be killed. In this way, the properties of the composition according to the invention that combat body or sweat odor can be further enhanced. Another advantage of ethanol is that the addition of preservatives is not necessary.

A suitable ethanolic carrier fluid is, for example, the commercially available product sold under the trade name Cosmetol (96% pure). This product contains 96 wt.% ethanol, 2 wt.% isopropanol, and 2 wt.% of 2-methylpropanol-2, each based on the total weight of the product.

Another advantage of using ethanol as a carrier fluid is that it forms a synergistic active complex with the at least one antiperspirant active ingredient according to the invention, whose sweat-inhibiting effect corresponds to that of a water-based, aluminum salt-containing cosmetic formulation.

The inventive composition comprises an ethanol content of 10 to 50 weight percent, particularly 15 to 40 weight percent, preferably 20 to 30 weight percent, based on the total weight of the composition. The synergistic effect of ethanol in combination with the at least one antiperspirant active ingredient provided according to the invention is particularly evident at the concentrations mentioned in this paragraph.

The cosmetic antiperspirant composition, in another embodiment, has a water content of 10 wt.% to 75 wt.%, preferably 35 wt.% to 50 wt.%, based on the total weight of the composition.

In a further embodiment, the cosmetic antiperspirant composition further contains Saccharomyces ferment. This is an end product of fermentation by Saccharomyces, i.e., a yeast sugar ferment. Such a ferment is commercially available, for example, under the trade names Deosent, DeoPlex Clear H5630. Saccharomyces ferment advantageously has a masking or reducing effect on odors. This effect is based on an enzymatic transformation of certain odor components, converting corresponding odor or fragrance substances into larger, heavier compounds which, due to their higher molecular weight, are no longer as easily volatile and therefore no longer perceived as odorous.

Preferably, the Saccharomyces ferment has a content of 0.5 to 5 weight percent, preferably 0.75 to 4 weight percent, more preferably 1 to 3 weight percent, based on the total weight of the composition.

In a further embodiment, the cosmetic antiperspirant composition further contains at least one pH regulator.
