FR 3 060 366 - A1 (54) ANHYDROUS DEODORANT COMPOSITIONS WITH ABSORBER COMBINATION.
(© The present invention relates to anhydrous cosmetic compositions which contain a combination of a highly swelling water-absorbing component and a low-swelling water-absorbing component, an odor-absorbing component and an active ingredient. These compositions have a remarkable deodorant effect as well as improved sensory properties and are also reflected in minimizing sweat stains on textiles. Furthermore, the present invention relates to a cosmetic product containing these anhydrous compositions as well as to the use of this composition or the product for the reduction of body odor caused by perspiration Finally, the present invention relates to the use of a highly swelling water-absorbing component and a water-absorbing component low swelling combined with an odor absorbing component for improving the sensory properties of deodorant compositions a hydrous.
The present invention relates to anhydrous cosmetic compositions, which contain at least one highly swelling water-absorbing component (A), at least one slightly swelling water-absorbing component (B), at least one odor-absorbing component (C) and at least one deodorant active principle (D). The use of the above-mentioned combination in anhydrous deodorant compositions results on the one hand in a dry skin sensation, on the other hand in a reduced formation of sweat spots on the textiles, as well as in a remarkable deodorant effect .
Furthermore, the present invention relates to a cosmetic product comprising the anhydrous cosmetic composition mentioned above, as well as at least one propellant (F).
In addition, the present invention relates to the use of the anhydrous cosmetic composition according to the invention or of the cosmetic product according to the invention for the reduction of the body odor caused by sweating.
Finally, the present invention relates to the use of a combination of at least one highly swelling water-absorbing component (A), at least one slightly swelling water-absorbing component (B) and at least one water-absorbing component. odors (C) for improving the sensory properties of anhydrous deodorant compositions.
Washing, cleaning and taking care of one's own body is a primary human need and modern industry is constantly trying to meet these human needs in various ways. Continuous elimination, or at least reduction, of body odor and underarm sweat is particularly important for daily hygiene. Many special deodorant or antiperspirant body care agents are known in the art, which have been designed for application in regions of the body having a high density of sweat glands, particularly in the axillary region. These are packaged in the most varied forms of distribution, for example in the form of powder, stick, aerosol spray, pump spray, liquid ball application or in the form of gel, cream, gel and flexible impregnated substrates (deodorant wipes).
The prior art cosmetic antiperspirants, used for the reduction of perspiration, contain at least one antiperspirant compound, in particular in the form of aluminum halides and / or hydroxyhalides, zirconium and aluminum. -zirconium. In combination with the acid value of the agent's pH, these compounds can however cause unpleasant skin reactions for some users. In addition, the use of the antiperspirant compounds mentioned above may cause staining on clothing.
There is therefore still a need for cosmetic agents which do not contain any aluminum salt and / or aluminum-zirconium antiperspirant, however which also reduce the formation of sweat stains on textiles. In addition to a good reduction in sweat spots, these agents must also be characterized by a good skin sensation, in particular a dry sensation, a good skin tolerance and must have a simple formula. In addition, these agents must be characterized by high storage stability.
The object of the present invention was to provide a deodorant composition which is characterized by a good skin sensation, by good skin tolerance, by a low degree of soiling for textiles and which is characterized by high stability in storage; in addition, it must reduce the formation of sweat stains on textiles.
Surprisingly, it then turned out that the use of a special combination of water-absorbing and odor-absorbing components in anhydrous cosmetic deodorant compositions results in both minimization of the formation of sweat stains on textiles only by a dry skin sensation. In addition, these compositions are characterized by a high skin tolerance as well as a high stability during storage, and do not cause the formation of undesirable stains on textiles.
The object of the present invention is therefore an anhydrous cosmetic composition containing
a) at least one highly swelling water-absorbing component (A),
b) at least one slightly swelling water-absorbing component (B)
c) at least one odor absorbing component (C) and
d) at least one deodorant active principle (D).
The exclusive use of the highly swelling water-absorbing component (A) allows a high absorption of moisture, and thus, a strong minimization of the formation of sweat stains on textiles. However, the high absorption of moisture implies that the component (A) partially dissolves or swells, and therefore leaves a greasy film on the skin. This film is perceived as unpleasant by consumers. However, the exclusive use of component (B) does not result in an unpleasant skin sensation, but the water absorption capacity of this component is insufficient. Surprisingly, it then turned out that the combination of the components (A) and (B) mentioned above also makes it possible to obtain a high capacity for absorbing water, and thus a reliable minimization of stains on textiles. , that a pleasant skin sensation. Without wishing to be limited to this theory, the addition of the slightly swelling water-absorbing component (B) results in a reduction or the avoidance of the fatty cutaneous sensation caused by the high absorption of large quantities of water by the component (A ), without having a negative effect on the high moisture absorption capacities of the component (A) however. Thus, the combination of the absorbents (A) and (B) in the anhydrous cosmetic agents of the present invention makes it possible not only to obtain a remarkable reduction in sweat stains on textiles, but also to obtain a dry skin sensation during the use of this composition. In addition, the combination of absorbents described above can be included in existing cosmetic formulas without special conditions, without causing incompatibilities and without causing less stability in storage. In addition, minimizing the amount of sweat provides an improved deodorant effect, since the breakdown of sweat by bacteria is avoided. This deodorant effect is further amplified by the use of the odor absorbing component (C) as well as the deodorant active ingredient (D).
In the context of the present invention, the term “anhydrous cosmetic compositions” designates cosmetic compositions which contain free water in a total amount of 0% by weight to 1% by weight, preferably 0 to 0.8% by weight, preferably 0% by weight to 0.5% by weight, in particular 0 to 0.2% by weight, respectively based on the total weight of the cosmetic composition. By “free water” in the sense of the present invention, is meant water which is different from water of crystallization, water of hydration or similar water linked molecularly or to the particles of the components used .
In addition, by “highly swelling water-absorbing component” is meant within the context of the present invention a compound which can absorb 10 to 50 times, in particular 20 to 40 times its own weight in water. Conversely, by “slightly swelling water absorbing component” is meant a compound which can absorb 1 to 9 times its own weight in water. The amount of water which is absorbed by the respective compound can for example be determined using the method described below. An erasing sponge (6.5 cm x 5.5 cm) is soaked with 75 g of a NaCl solution 1% by weight in a Petri dish (diameter 11 cm) by pressure. In addition, 50 g of 1% by weight NaCl solution are added to the sponge. Subsequently, the water absorption of the round black band filter used (diameter 55 mm) is determined in the weighing thereof, placed on the erasing sponge soaked for 30 minutes, then is weighed again after elimination excess filter water by suction using a water pump (for 30 sec.). The difference between the weight of the hardened filter and the weight of the dry filter gives the factor F _f of the water absorption capacity of the filter. Following this, the absorption capacity of the respective compound F _v is determined by the fact of slightly distributing 0.2 g of this compound on a dry black band filter (diameter 55 mm), of depositing drop by drop 2 g of a 1% by weight NaCl solution on the powder and then place the filter on the soaked eraser sponge for 30 minutes. After removing excess water by suction using a water pump (for 30 sec.), The weight of the filter on which the wet compound is located is calculated. As such, care should be taken that the black band filters used to determine the water absorption capacity of the filter and the respective compound are from the same batch. The water absorption capacity of the respective compound F _v can be calculated using the formula F _v = m (filter + wet powder) - m (powder) - m (filter) * F _f , each compound making the subject of a quadruple determination, the average value of which is then calculated.
Furthermore, by the term “deodorant active principle”, it is understood in the context of the present invention a compound which has antimicrobial and / or enzyme inhibitor properties. In addition, this also includes compounds that can cover unpleasant body odors caused by the breakdown of sweat or positively alter the perception of body odors. The components (A) and (B) previously mentioned do not belong to the deodorant active principles according to the invention. Preferably, the deodorant active principles are not aluminum or aluminum-zirconium antiperspirant salts. The preferred anhydrous cosmetic agents of the present invention therefore contain, based on the total weight of the cosmetic composition, 0% by weight of aluminum and / or aluminum-zirconium antiperspirant salts.
Finally, by the term “odor-absorbing component”, it is understood in the context of the present invention a component which can absorb liquid and / or gaseous and / or solid compounds in a reversible and / or irreversible manner, preferably irreversibly.
The indications in% by weight refer herein, unless otherwise indicated, to the total weight of the anhydrous cosmetic composition according to the invention.
The anhydrous cosmetic compositions according to the invention contain, as the first essential component, at least one strongly swelling water-absorbing component (A). In the context of the present invention, it is preferable to use certain compounds as component (A). Preferred embodiments of the present invention are therefore characterized in that the at least one highly swelling water-absorbing component (A) is selected from the group consisting of xanthan gum, gellan gum, cellulose, cellulose ethers, linear sodium polyacrylates, alginic acid and its salts, carrageenan and its salts, agar agar, pectins, guar gum, starch ethers, starch esters, locust bean gum, gelatins, succinoglycan polyvinylpyrrolidone, crosslinked copolymers of acrylamide and acrylic acid, tara gum, as well as their mixtures, in particular of sodium carboxymethylcellulose and / or crosslinked copolymers of acrylamide and acrylic acid. Preferably, sodium salts of alginic acid are used as well as sodium, potassium, magnesium and calcium salts of carrageenan. In addition, sodium carboxymethylcellulose can be used as the cellulose ether. As examples of a suitable starch ester according to the invention, mention may be made of hydroxypropyl starch phosphates as well as hydroxypropyl diamidon phosphates. Succinoglycans are polysaccharides with repeating units of bacterial origin, which respectively consist of seven units of glucose and one unit of galactose. Tara gum (also called Cesalpina Spinosa gum) can be obtained by spraying the seeds of the Caesalpinia spinose plant. The particularly swelling water-absorbing components (A) which are particularly preferred are sodium carboxymethylcellulose (for example sold under the brand Cekol 30000 from the company CP Kelco) and / or crosslinked copolymers of acrylamide and of acrylic acid (for example sold under the brand Aquasorb A 100 from the company Ashland). The use of the above-mentioned component (A), in particular sodium carboxymethylcellulose, results in a particularly good reduction of sweat stains on textiles due to its high capacity for absorbing moisture.
According to the invention, it has proved advantageous that the component (A) is used in the form of a powder with a determined average particle size.
According to the invention, it is therefore preferable for the at least one strongly swelling water-absorbing component (A) to be in the form of particles, in which at least 30% by weight of the component (A) has an average particle size D ₅₀ greater than 10 μm and in which 100% by weight of component (A) has an average particle size D ₅₀ less than 200 μm. The indication of% by weight relates in this respect to the total weight of the component (A). The mean particle size D ₅₀ can for example be determined using dynamic light scattering (DLS). The use of component (A) with the above-mentioned average particle sizes results in particularly good absorption of moisture, without however adversely affecting the storage stability.
In the context of the present invention, it is preferable to use the component (A) in ranges of determined quantities. According to the invention, it is therefore advantageous for the at least one strongly swelling water-absorbing component (A), in particular sodium carboxymethylcellulose and / or crosslinked copolymers of acrylamide and acrylic acid, to be present in a total amount ranging from 1.0 to 40% by weight, preferably from 1.5 to 30% by weight, preferably from 2.0 to 20% by weight, in particular from 3.0 to 15% by weight, based on the total weight of the anhydrous cosmetic composition. The quantity indications previously mentioned relate to the total quantity in component (A). If only a single compound is used as component (A), then these quantity indications relate to the total quantity of the single compound. If, on the other hand, a mixture of different components (A) is used, then the above quantity indications relate to the total amount of the mixture of the different components (A). The use of the above-mentioned total amounts results in a particularly high moisture absorption and thus, a remarkable reduction in sweat stains on textiles. On the other hand, the dry skin sensation obtained by the additional use of component (B) is not negatively influenced, even in the event of absorption of large amounts of moisture by component (A). In addition, the use of the total amounts previously mentioned does not have a negative consequence on the storage stability of the cosmetic composition according to the invention.
The anhydrous cosmetic compositions according to the invention contain, as a second essential component, at least one slightly swelling water-absorbing component (B). According to the invention, certain compounds are preferably used as components (B). In the context of the present invention, it is therefore advantageous that the at least one slightly swelling water-absorbing component (B) is selected from the group consisting of celluloses, silica, modified silica, as well as mixtures of these, in particular from silica and / or hydrophilic cellulose. The cellulose gums previously mentioned in connection with component (A) do not, however, count among the celluloses and microcrystalline celluloses mentioned above. The modified silica can for example be obtained by surface modification using different chemical compounds. The slightly swelling water-absorbing components (B) used in a particularly preferred manner in the context of the present invention are hydrophilic silica with a BET surface area of 250 to 350 m ² / g (for example sold under the brand Aeropearl® 300/30 from the company Evonik) and / or cellulose (for example sold under the name Sensocel OC 30 G from the company CFF). The use of the components (B) mentioned above, in particular the hydrophilic silica provided with a BET surface of 250 to 350 m ² / g and / or cellulose, prevents the formation of a greasy film by the component (A), which results in a dry skin feeling. Because of this, the high moisture absorption capacity of component (A) is not negatively influenced, so that a good reduction in sweat stains on textiles is obtained.
According to the invention, it has proven to be advantageous for component (B) to also be used in the form of a powder with a determined average particle size. The preferred embodiments of the present invention are therefore characterized in that the at least one low-swelling water-absorbing component (B) is in the form of particles, in which at least 30% by weight of the component (B) has an average particle size D ₅₀ greater than 10 μm and in which 100% by weight of the component (B) has an average particle size D ₅ o less than 200 μm. The indication of% by weight relates in this respect to the total weight of the component (B). The average particle size D ₅₀ can for example be determined using dynamic light scattering (DLS dynamic light scattering). The use of component (B) with the above-mentioned average particle sizes results in a particularly dry skin sensation, without adversely affecting the moisture absorption capacity of component (A), however.
In the context of the present invention, it is preferable to use component (B) in ranges of determined quantities. According to the invention, it is therefore advantageous for the at least one slightly swelling water-absorbing component (B), in particular silica and / or hydrophilic cellulose, to be present in a total amount ranging from 1.0 to 40 % by weight, preferably from 1.5 to 30% by weight, preferably from 2.0 to 20% by weight, in particular from 2.0 to 15% by weight, based on the total weight of the anhydrous cosmetic composition . The quantity indications previously mentioned relate to the total quantity in component (B). If only a single compound is used as component (B), then these quantity indications relate to the total quantity of the single compound. If, on the other hand, a mixture of different components (B) is used, then the above quantity indications relate to the total amount of the mixture of the different components (B). The use of the total amounts previously mentioned results in a particularly dry skin sensation, even in the case of absorption of large amounts of moisture by the component (A). In addition, the use of the total amounts previously mentioned does not have a negative consequence on the moisture absorption capacity of the component (A) nor on the storage stability of the cosmetic composition according to the invention.
Preferred embodiments of the present invention include a determined weight ratio of component (A) to component (B). The use of these weight ratios has been found to be particularly advantageous for absorbing moisture, and thus for reducing sweat stains on textiles on the one hand, and for dry skin sensation on the other. go. According to the invention, it is therefore preferable that the anhydrous cosmetic composition comprises a weight ratio of the at least one highly swelling water-absorbing component (A) to the at least one slightly swelling water-absorbing component (B ) from 8: 2 to 2: 8, preferably from 7: 2 to 2: 7, in particular from 7: 3 to 4: 6.

By active carbon derivatives is meant in the context of the present invention active carbon which has been modified using chemical and / or physical processes. In addition, the term “diatoms” is understood to mean unicellular algae, the cell wall of which mainly consists of silicon dioxide. In addition, starch derivatives are understood to mean starches which have been modified using chemical reactions or which have been hydrolyzed using enzymes. The previously mentioned isolated plant components can also be ground and used in powder form.

The quantity indications previously mentioned relate to the total quantity in component (C). If only a single compound is used as component (C), then these quantity indications relate to the total quantity of the single compound. If, on the other hand, a mixture of different components (C) is used, then the indications of quantities above relate to the total amount of the mixture of the different components (C). The use of the total amounts mentioned above results in a particularly high reinforcement of the deodorant effect as well as of the dry skin sensation of the composition according to the invention. In addition, the use of the total amounts mentioned above does not have a negative consequence on the moisture absorption capacity of components (A) and (B), nor on the storage stability of the cosmetic composition. according to the invention.
