Description

The present invention relates to antiperspirant cosmetic compositions with specific water-soluble polysaccharides, which have an improved adsorption of antiperspirant compounds on the skin, a reduced loss of activity and a reduction and / or prevention of staining on textiles.

Furthermore, the present invention relates to the use of antiperspirant cosmetic agents with specific water-soluble polysaccharides for reducing and / or preventing perspiration.

Finally, the present invention relates to the use of specific water-soluble polysaccharides to improve the adsorption of antiperspirant compounds on the skin and to reduce the loss of efficacy of antiperspirant compounds.

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).

With regular use, antiperspirants can lead to clearly visible colored textile stains. Often these are yellow spots, which can not be removed by intensive washing. The staining is based on a complex interaction of prescription constituents of the antiperspirant, sweat and the detergent used. Initially, insoluble aluminum compounds of unsaturated fatty acids are likely to form on and within the fiber. The yellowing usually occurs with a time delay and is at least partially caused by oxidation of unsaturated fatty acids present as insoluble aluminum salts.

Furthermore, the particles of the antiperspirant active substances adsorbed on the skin after the application of the antiperspirant can detach and be absorbed by the textile. Due to the lower amount of desorbed particles of the antiperspirant active on the skin, a loss of efficacy may result in reduced antiperspirant performance. On the other hand, the detachment and coating of the antiperspirant active ingredients on the textile can lead to staining, since the interaction of detergents and particles of the antiperspirant active ingredients applied to the textile gives rise to insoluble compounds. These insoluble compounds form white, hard residues, which usually show up after several soiling and washing cycles on the textile. These white residues are insoluble in water and can not be removed by standard washing procedures. They are particularly noticeable on light or dark colored textiles.

In order to avoid a loss of active ingredient of the antiperspirant and permanent contamination by adsorption of antiperspirant active ingredients applied to the skin on textiles, various ingredients are added in the prior art. A commonly used additive are surfactants, such as in the document WO 2010/097205 A2 described. Also, the choice of oil components can reduce or increase the level of fabric contamination, as in the documents US 5,925,338 A . US Pat. No. 4,511,554 A or US Pat. No. 3,974,270 described.

There is therefore still a need for ingredients in antiperspirants which are able to improve the adsorption of antiperspirant active ingredients applied to the skin in order to effectively reduce and / or prevent the loss of efficacy of the antiperspirant and permanent fouling of textiles.

The present invention has for its object to provide an ingredient in antiperspirant cosmetic agents, which avoids or at least mitigates the disadvantages of the prior art and which is able to improve the adsorption of antiperspirant active ingredients applied to the skin and thus a loss of activity as well Minimize or avoid textile soiling. Furthermore, the ingredient should have no negative impact on the stability of the antiperspirant have cosmetic agents and be used both in propellant-containing and propellant-free formulations.

It has now surprisingly been found that the use of special water-soluble polysaccharides in antiperspirant cosmetic agents leads to an improved adsorption of antiperspirant compounds or antiperspirant active ingredients on the skin. On the one hand, this improved adsorption increases the product performance or the antiperspirant effect and, on the other hand, avoids textile soiling, which can form on textiles as a result of the deposition of insufficiently adsorbed antiperspirant active ingredients. Furthermore, the special water-soluble polymer does not have a negative influence on the product stability and can be used both in propellant-free and in propellant-containing formulations.

• a) mindestens ein wasserlösliches Polysaccharid, ausgewählt aus linearen Homopolymeren von Maltotrioseeinheiten,
• b) mindestens eine schweißhemmende Verbindung in einer Gesamtmenge von 1 bis 40 Gew.-%, bezogen auf das Gesamtgewicht des treibmittelfreien schweißhemmenden kosmetischen Mittels, und
• c) Treibmittel in einer Gesamtmenge von 0 bis 95 Gew.-%, bezogen auf das Gesamtgewicht des schweißhemmenden kosmetischen Mittels.

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

• a) at least one water-soluble polysaccharide selected from linear homopolymers of maltotriose units,
• b) at least one antiperspirant compound in a total amount of 1 to 40 wt .-%, based on the total weight of the blowing agent-free antiperspirant cosmetic agent, and
• c) blowing agent in a total amount of 0 to 95 wt .-%, based on the total weight of the antiperspirant cosmetic agent.

The use of special water-soluble polysaccharides in antiperspirant cosmetic products leads - without wishing to be limited to this theory - to an improved adsorption of the antiperspirant compound after applying the antiperspirant cosmetic agent to the skin. By evaporation of the antiperspirant cosmetic agent, the particular water-soluble polymer forms a film on the skin which entraps the antiperspirant compound thereby reducing or preventing desorption of the antiperspirant compound onto the fabric and thus loss of antiperspirant performance and staining , The film formed is extremely flexible and tear-resistant, thus ensuring reliable containment of the antiperspirant compound as well as reliable adhesion of the film to the skin even during movement. However, due to the water-solubility of the film, rapid release of the entrapped antiperspirant compound and thus excellent antiperspirant effect are ensured at the same time.

Furthermore, the use of the special water-soluble polysaccharides does not lead to a reduced storage stability due to a negative influence of these polysaccharides on the product stability. In addition, these polysaccharides can be used both in propellant-containing and in propellant-free antiperspirant cosmetic agents and thus allow flexible and customized to the customer's formulations.

In addition, the special water-soluble polysaccharides are easily accessible natural raw materials, which are ecologically excellent degradable and thus pose no burden on the environment.

In the context of the present invention, the term "antiperspirant cosmetic agent" is understood to mean a cosmetic agent which is able to reduce or reduce perspiration of the sweat glands of the body.

Furthermore, the term "polysaccharides" in the context of the present invention are to be understood as meaning carbohydrates in which at least 9 monosaccharides or simple sugars are linked via a glycosidic bond. As the glycosidic bond, the chemical bond between the anomeric carbon atom of the first saccharide and a heteroatom, especially an oxygen atom, of the second saccharide is referred to.

In addition, in the context of the present invention, the term "water-soluble polysaccharides" is to be understood as meaning polysaccharides which have a water solubility of at least 7% by weight at 20 ° C., ie. H. at least 7 g of the polysaccharide dissolve in 93 g of water at 20 ° C.

In addition, the term "homopolymers" in the context of the present invention means polymers which are composed exclusively of a single monomeric compound, ie. H. The polymer consists exclusively of identical or identical monomers.

Furthermore, the term "maltotriose units" in the context of the present invention means units which are obtained by α-1,4-glycosidic linkage of three glucose molecules and correspond to the formula (I):

Finally, in the context of the present invention, the term "antiperspirant compound" is understood as meaning a compound which is able to reduce or reduce the perspiration of the sweat glands of the body.

The statement wt .-% relates in the present case, unless stated otherwise, to the total weight of the antiperspirant cosmetic agents used according to the invention without any propellant present.

According to a preferred embodiment of the present invention, the water-soluble polysaccharide is selected from nonionic linear homopolymers of maltotriose units.

Furthermore, it is preferred in the context of the present invention for the maltotriose units of the linear homopolymers to be linked by α-1,6-glycosidic bonds. The term α-1,6-glycosidic bond is understood here to mean the type and position of the linkage of second maltotriose units, where α denotes the type of linkage and 1.6 denotes the position of the carbon atoms participating in the linkage. The water-soluble polysaccharides used according to the invention thus contain the linkage of the maltotriose units shown according to the formula (II):

It may be preferable in the present invention that the water-soluble polysaccharide selected from linear homopolymers of maltotriose units has a weight-average molecular weight M _w of 5,000 to 800,000 Da, preferably 6,000 to 750,000 Da, preferably 7,000 to 600,000 Da, more preferably from 8,000 to 550,000 Da, in particular from 9,000 to 450,000 Da. The average molecular weight M _w can be determined, for example, by gel permeation chromatography (GPC) using polystyrene as an internal standard according to DIN 55672-3 be determined.

Particularly good results with regard to the reduction of the loss of effect of the antiperspirant compound and the reduction or avoidance of textile discolorations and / or textile stains are obtained in the context of the present invention, when the water-soluble polysaccharide is selected from pullulan. The name pullulan refers to a water-soluble linear polysaccharide consisting exclusively of maltotriose units linked by α-1,6-glycosidic bonds and having an average molecular weight of 10,000 to 400,000 daltons. For example, pullulan can from starch and sugar using the fungus Aureobasidium pullulans. In addition, it can also be obtained commercially, for example from the company Hayashibara.

According to a preferred embodiment of the present invention, the water-soluble polysaccharide selected from linear homopolymers of maltotriose units, in a total amount of 0.1 to 15 wt .-%, preferably from 0.2 to 10 wt .-%, preferably from 0.3 to 7 wt .-%, more preferably from 0.4 to 5 wt .-%, in particular from 0.5 to 3 wt .-%, based on the total weight of the blowing agent-free antiperspirant cosmetic agent. Without wishing to be limited by this theory, the use of the abovementioned amounts of the water-soluble polysaccharide selected from linear homopolymers of maltotriose units results in film formation after evaporation of the solvent of the antiperspirant cosmetic agent on the skin and thus inclusion of the antiperspirant compound. This inclusion increases the adsorption of this compound on the skin and effectively prevents transmission to the textile, which can lead to loss of effect as well as textile stains or textile discolorations. The film formed at these levels is extremely flexible and tear resistant, thus ensuring reliable containment of the antiperspirant compound as well as reliable adhesion of the film to the skin even during exercise. Due to the high water solubility of the film formed also a rapid release of the antiperspirant compound and thus an excellent antiperspirant effect is ensured. The use of the amounts mentioned above thus results in a reduced loss of effect of the antiperspirant compound and in a prevention or reduction of textile stains or textile discolorations. Furthermore, when employing the aforementioned amounts of the water-soluble polysaccharide selected from linear homopolymers of maltotriose units, there are no deteriorated storage stabilities or incompatibilities with other ingredients. In addition, these quantities can be easily incorporated into both propellant-free and propellant-containing formulations.

In a further preferred embodiment, the antiperspirant cosmetic agents according to the invention are characterized in that they are formulated as an oil-in-water emulsion and, based on the total weight of the propellant-free antiperspirant cosmetic agent,

• At least one water-soluble polysaccharide selected from linear homopolymers of maltotriose units, in a total amount of from 0.1 to 15% by weight, preferably from 0.2 to 10% by weight, preferably from 0.3 to 7% by weight. %, more preferably from 0.4 to 5 wt .-%, in particular from 0.5 to 3 wt .-%,

contain. It may be provided in the context of the present invention that the embodiment mentioned above is formulated as a propellant-free or as propellant-containing antiperspirant cosmetic agent. In the case of packaging as propellant-containing agent, the aforementioned antiperspirant cosmetic agent is mixed with a propellant, in particular a mixture of propane and butane. In the context of this embodiment, however, the sweat-inhibiting cosmetic agent according to the invention is preferably made up without blowing agent.

A second object of the present invention is the use of an antiperspirant cosmetic agent according to the invention for reducing and / or preventing perspiration. With regard to this use of the antiperspirant cosmetic agents according to the invention, what has been said with respect to the inventive and inventively preferred antiperspirant cosmetic agents applies mutatis mutandis.

Further, a third object of the present invention is the use of at least one water-soluble polysaccharide selected from linear homopolymers of maltotriose units to improve the adsorption of antiperspirant compounds on the skin and to reduce the loss of antiperspirant compounds. By using the special water-soluble polysaccharide selected from linear homopolymers of maltotriose units, the adsorption of the antiperspirant compound on the skin can be increased. This improved adsorption, without wishing to be bound by theory, results from the inclusion of the antiperspirant compound due to film formation of the water-soluble polysaccharide selected from linear homopolymers of maltotriose units, during evaporation of the antiperspirant cosmetic agent solvent. The film formed is extremely flexible and tear-resistant, thus ensuring reliable containment of the antiperspirant compound as well as reliable adhesion of the film to the skin even during movement. In addition, this film is extremely water-soluble, so that a rapid release of the included antiperspirant compound and thus a fast antiperspirant effect is ensured. The improved adsorption of the antiperspirant compound to the skin due to film formation leads to a reduction or avoidance of an active loss as a result of the desorption of the antiperspirant compound from the skin to textiles. Regarding this use of the water-soluble polysaccharide selected from linear homopolymers of maltotriose units, what has been said with respect to the inventive and preferred antiperspirant cosmetic agents according to the invention applies mutatis mutandis.

In addition, a fourth object of the present invention is the use of at least one water-soluble polysaccharide selected from linear homopolymers of maltotriose units for reducing and / or preventing textile discolorations and / or textile stains. The film formed using the particular water-soluble polysaccharide reduces the desorption of the antiperspirant compound from the skin onto the fabric and, consequently, the amount of antiperspirant compound on the fabric. Thus, there is a reduction or avoidance of textile stains due to reactions of the antiperspirant compound with components of the sweat or the detergent on the textile.

The term "textile discoloration" or the term "textile stain" in the context of the present invention means staining of the textile by antiperspirant cosmetic agents, wherein the staining of the textile can be white and / or greasy.

With regard to this use of the water-soluble polysaccharide selected from linear homopolymers of maltotriose units, what has been said with respect to the inventive and inventively preferred antiperspirant cosmetic agents applies mutatis mutandis.

Finally, a fourth subject of the present application is a non-therapeutic cosmetic method for preventing and / or reducing the transpiration of the body, in which an antiperspirant cosmetic agent according to the invention is applied to the skin, in particular to the skin of the armpits. With regard to the non-therapeutic method, mutatis mutandis, the statements made on the inventive and inventively preferred antiperspirant cosmetic agents and on the uses according to the invention apply.
