    Description
    Title of the invention: Anhydrous antiperspirant suspensions with improved stability [0001] The present invention relates to an antiperspirant composition for application by a ball tube, which composition is advantageously usable in applicators of the ball tube type. In addition, the present invention relates to an applicator of the ball-tube type comprising a composition according to the invention, as well as to a non-therapeutic use of a composition according to the invention.
    Washing, cleaning and taking care of your own body is a primary human need. Manufacturers of personal care products are constantly trying to meet these public needs in many ways. The permanent elimination or at least the reduction of body odors are particularly important for daily hygiene. Numerous specific deodorant body care products are known in the state of the art, which products have been developed for use in regions of the body having a high density of sweat glands, in particular in the armpit area and at the level of the armpits. feet.
    Body odors come largely from the bacterial breakdown of different components of sweat on the skin. During bodily deodorization, one can roughly differentiate the active ingredients which absorb (zinc ricinoleate, cyclodextrins, ion exchangers) or cover (fragrances, perfumes) substances with an unpleasant odor already formed, active ingredients which prevent or at least slow down (active inhibitors of germs, prebiotic components and inhibitors of enzymes) the breakdown of sweat and the formation of unpleasant odorous substances. Depending on the mechanism chosen to prevent body odor, it is possible to use, as cosmetic deodorant active principles, odor absorbers, perfumes, deodorant ion exchangers, antimicrobial agents, prebiotic components and enzyme inhibitors. The active ingredients must be present in the compositions, and thus guarantee that the composition can be applied to the skin and that the antiperspirant active ingredient reaches its site of action. Simultaneously, the compositions should be able to be appropriately supplied in a desired dosage form and the compositions should not cause an unpleasant sensation on the skin.
    The compositions can be formulated in very varied dosage forms, for example in the form of powder, stick, aerosol spray, pump spray, ball application of a liquid or gel product, of cream , gel and impregnated flexible substrates (deodorant wipes). The dosage form determines the form and ingredients of the compositions. For example, if the composition is supplied in powder form, its ingredients must form a free-flowing solid; for example, if the composition is provided in the form of a stick, it should form a viscous composition having a creamy texture; and if the dosage form is an aerosol spray or a pump spray, for example, certain antiperspirant active ingredients should not be used. The development of the desired dosage forms must take into account the corresponding boundary conditions.
    A very popular dosage form with consumers is that of the deodorant roller, also called a ball applicator. In this dosage form, a known antiperspirant composition is found in a container comprising a ball which can be brought into contact with the antiperspirant composition inside the container, where, by an induced rotation, a film (consisting of the antiperspirant composition) lying on the surface of the ball can be guided on the outer part of the ball applicator by a slot between the ball and the container, by which the antiperspirant composition can be applied from there.
    In the known compositions used in ball applicators as a dosage form, particulate salts comprising aluminum and / or zirconium are used as highly effective deodorant and antiperspirant active ingredients. The compositions known in ball applicators therefore constitute suspensions. However, suspensions have drawbacks affecting their stability. The solids in the compositions can settle out so that the user must shake the ball applicator before use to ensure even distribution of the ingredients. In addition, the fluids dissociated after sedimentation and / or syneresis, in particular the silicone oil frequently used in these compositions, are very fine and, in the case of a lateral position or in the pear tree position of the ball applicator , reach the outside through the space between the ball and the housing. This leakage problem has not been satisfactorily resolved so far.
    The underlying object of the present invention is to provide an antiperspirant composition which is particularly well suited for use in a ball applicator. In particular, the object of the invention was to provide an antiperspirant composition used in a ball applicator having no tendency to leak or, at least, a reduced tendency to leak.
    The mission which the invention must fulfill is accomplished by the subject of the claim
    1. A first object of the present invention is therefore an antiperspirant composition for application by a ball comprising a) at least one antiperspirant active principle comprising an inorganic or organic salt of aluminum, zirconium or a mixture of these ci, b) a rice starch and c) a hydrophobically modified clay mineral.
    Surprisingly, it has been found that this composition considerably reduces the leakage problem inherent in ball applicators. The advantage associated with the composition according to the invention is also due to a more stable suspension. The antiperspirant composition according to the invention is characterized by a reduced tendency of the solid components to flow and a weaker tendency to syneresis. In addition, the rheological behavior is jointly responsible for the beneficial properties associated with the antiperspirant composition. It is therefore particularly advantageous to use it in ball applicators.
    By application by ball means any application to prevent body odor with the use of a ball applicator. By “ball applicator” is meant any device comprising a housing and a ball through which the antiperspirant composition is released. The term "ball applicator" is used as a synonym for the term "ball deodorant".
    The antiperspirant composition necessarily comprises an antiperspirant active principle comprising an inorganic or organic salt of aluminum and / or zirconium. By this is meant that the antiperspirant composition contains an inorganic or organic salt of aluminum and / or an inorganic or organic salt of zirconium. Furthermore, as a variant, inorganic or organic salts of aluminum or zirconium mixtures can be included in the antiperspirant composition. The antiperspirant active ingredients have no direct influence on the activity of the sweat glands but considerably reduce the secretion of sweat by narrowing the flow pathways. The salts of Al and Zr have the effect of inhibiting perspiration on the surfaces of skin treated by a superficial obstruction of the pathways of the sweat glands, by precipitation of metallic mucopolysaccharide.
    “Rice starch” means any starch obtained from rice. Starch is a reserve carbohydrate which is stored by many plants in the form of starch grains (granules), generally measuring from 1 to 200 µm, in various parts of plants, for example in tubers or roots, seeds, fruits and in the pulp. Starch belongs to the homoglycan family and is a polycondensation product of D-glucose. In this case, the starch consists of three structurally different polymers of Dglucopyranose, namely amylose, amylopectin and a so-called intermediate fraction. The higher plants contain from 0 to 45% by weight of amylose, based on the dry matter. The intermediate fraction, also called abnormal amylopectin, is found structurally between amylose and amylopectin.
    Amylose consists of D-glucose linked al, 4-glycosidically, M w from 50,000 to
    150,000. The resulting chains form double helices in the starch. Amylopectin contains, in addition to the a-1,4 bonds described for amylose, an amount of 4 to 6%, a-1,6 bonds as branching points. The average distance between branch points is approximately 12 to 17 glucose units. The molar mass of 10 7 to 7 × 10 8 corresponds to approximately 10 5 units of glucose, amylopectin therefore belonging to the largest biopolymers. Said ramifications are distributed over the molecule so that a herringbone structure develops with relatively short side chains.
    In addition to the binding and the associated amylopectin and amylose contents as well as the molecular weight, the macroscopic structure of the particles plays an important role in the properties of starch. The origin of the starch significantly determines the size, size distribution and shape of the starch granules. The above chemical and structural differences result in properties that make the selected rice starch particularly suitable for the application in question.
    As can be seen from the examples, the best results are obtained when the rice starch (b) is derived from the plant species Oryza sativa. Starch derived from this plant species has surprisingly the best results. The properties of the structure, chemical composition, size and / or size distribution of the starch grains seem to have particularly advantageous effects with this starch. In a particularly preferred and advantageous embodiment of the present invention, the antiperspirant composition of the present invention therefore comprises a rice starch derived from rice starch from Oryza Sativa.
    According to another preferred embodiment of the present invention, the rice starch (b) is present in the antiperspirant composition in the form of a powder treated with a cationic surfactant, the amount of the cationic surfactant preferably being 0.01 to 1% by weight, more preferably 0.03 to 0.3% by weight, based on the weight of the treated rice starch. The quantities indicated refer to the quantities by weight used in the production of treated rice starch. For example, for a rice starch treated at 1 percent by weight, 1 part by weight of cationic surfactant is treated with 99 parts by weight of rice starch.
    Of course, the production of the treated rice starch can also be carried out in the form of a suspension. Preferred cationic surfactants are alkylammonium halides in which at least one alkyl group contains from 8 to 24 carbon atoms, more preferably from 10 to 20 carbon atoms, most preferably from 14 to 18 carbon atoms . For example, preferred rice starches are treated with cetrimonium chloride.
    Rice starch D.S.A. 7 of Agrana AG is a commercially available rice starch with proven beneficial effects.
    In a preferred embodiment of the present invention, the rice starch (b) is present in the antiperspirant composition in an amount ranging from 0.1 to 10% by weight, preferably 0.2 to 5% by weight, more preferably from 0.4 to 2% by weight, based on the total weight of the antiperspirant composition. Rice starch has advantageous effects in these ranges of quantities. The preferred amount ranges apply to rice starch and processed rice starch.
    The term "clay mineral" must be understood in the context of the present application as generally defined in the specialized documentation. In this regard, reference is made to the definition given by Rômpp ("Rômpp Lexikon Chemie", J. Falbe, M. Regitz (Hrsg.), 10. Auflage, Thieme-Verlag). According to the latter, the vast majority of clay minerals belong to phyllosilicates, also called lamellar silicates, but also to strip silicates. The structure of phyllosilicates can be described by layers of SiO 4 tetrahedra linked to layers of silicate tetrahedra. The layers of tetrahedra are linked to layers of octahedra, the octahedra having different metals, in particular ΓΑ1, Mg, Fe in the center. Depending on the valence of the metals in the center of the octahedron layer (in some cases also, the tetrahedron layer, if Si is not in the center of the tetrahedron), mono- or divalent ions are compensated at the surface the octahedron layer (or the tetrahedron layer) for external neutrality. For some clay minerals, water can infiltrate between layers, so these clay minerals can swell. The tetrahedron layers and the octahedron layers alternate along the C axis of the crystal. In a sequence in which a layer of tetrahedra is always followed by a layer of octahedra, we speak of a clay mineral with two layers; if a layer of octahedra is between two layers of tetrahedra, we speak of a clay mineral with three layers.
    According to a preferred embodiment of the present invention, the clay mineral is a phyllosilicate, that is to say. that the hydrophobically modified clay mineral is preferably a hydrophobically modified phyllosilicate. More preferably, the hydrophobically modified phyllosilicate is a hydrophobically modified three-layer silicate, more preferably a swellable hydrophobically modified three-layer silicate.
    The term “hydrophobically modified clay minerals” is understood to mean clay minerals in which the naturally occurring metal cations are replaced in whole or in part by cations substituted by hydrophobic groups, preferably ammonium cations substituted by long chain alkyl groups. , long chain alkyl groups preferably containing from 5 to 30, particularly preferably from 7 to 25 and most preferably from 10 to 20 carbon atoms.
    The advantage of hydrophobically modified clay minerals is compatibility with organic solvents.
    The production of hydrophobically modified clay minerals includes any contacting of clay minerals with salts comprising cations with hydrophobic groups. For example, the clay minerals can be suspended in a liquid medium, in which cations comprising hydrophobic groups are in dissolved form, the liquid phase being separated after contacting and the clay minerals thus rendered hydrophobic being dried.
    According to a preferred embodiment of the present invention, the hydrophobically modified clay mineral (c) is a hydrophobically modified phyllosilicate, preferably a hydrophobically modified kaolinite, a hydrophobically modified hectorite, a hydrophobically modified halloysite, a hydrophobically modified ilite, a hydrophobically modified beidellite, a hydrophobically modified nontronite, a hydrophobically modified saponite, a hydrophobically modified smectite, a hydrophobically modified montmorillonite or a hydrophobically modified bentonite. The use of a hydrophobically modified bentonite in the antiperspirant composition according to the invention is very particularly advantageous.
    It has been confirmed experimentally that the choice of phyllosilicate has a significant influence on the stability properties of the antiperspirant composition according to the invention. In particular, bentonite has advantageous effects in the antiperspirant composition. Bentonite is a clay mineral containing montmorillonite as the main constituent. This significantly influences the swelling properties of the clay mineral.
    The mechanical properties of clay mineral fluids are influenced by the montmorillonite content. Preferably, a bentonite containing more than 50%, preferably more than 60%, more preferably more than 70%, even more preferably more than 80% of montmorillonite, will be used. A suitable commercially available clay mineral intended for use in the composition according to the invention is the product Bentone 38 V CG.
    According to another preferred embodiment of the present invention, the antiperspirant composition contains the hydrophobically modified clay mineral (c) in an amount ranging from 1 to 10% by weight, preferably from 1.5 to 7, 5% by weight, more preferably 2 to 5% by weight, based on the total weight of the antiperspirant composition. The hydrophobically modified clay mineral is particularly advantageous in these ranges of quantities.
    The composition according to the invention, very particularly a composition comprising hydrophobically modified bentonite with rice starch derived from the plant species Oryza sativa, is surprisingly suitable for reducing the problem of leaks, under- underlying the invention. However, an obvious starting point for finding a solution to the initial mission of the invention would initially be of a constructive nature, that is to say it would be quite obvious to change the arrangement of the ball. in the housing in some way or to optimize the shape of the ball bed in order to considerably reduce the appearance of leakage of liquids from the ball applicator. However, the problem can often not be resolved satisfactorily by constructive measures. On the one hand, the space between the ball and the housing must be wide enough to allow a sufficiently thick film to exit the housing; on the other hand, the space should not be too large, to prevent the problem of leaks from worsening. The fact that an antiperspirant composition can be developed to alleviate or eliminate the leakage problem can, in itself, be considered surprising.
    The best results for accomplishing the mission underlying the invention have been obtained by antiperspirant compositions comprising at least one active principle comprising an inorganic or organic salt of aluminum, zirconium or a mixture thereof, a rice starch derived from the plant species Oryza sativa, and a hydrophobically modified bentonite. This is unpredictable on the bottom, since the types of starch and the types of clay minerals have a number of parameters which can be modified in order to influence and improve the properties of the compositions.
    According to a preferred embodiment of the present invention, the antiperspirant active ingredient (a) is soluble in water. According to another preferred embodiment of the present invention, the antiperspirant active principle (a) is chosen from an aluminum chlorohydrate, preferably aluminum sesquichlorohydrate, chlorohydrex propylene aluminum glycol (PG), chlorohydrex aluminum polyethylene glycol (PEG), aluminum sesquichlorohydrex PG, aluminum sesquichlorohydrex PEG, aluminum dichlorhydrex PG, or aluminum dichlorhydrex PEG or aluminum hydroxide; or is chosen from an aluminum-zirconium hydrochloride, preferably an aluminum-zirconium trichlorohydrate, an aluminum-zirconium tetrachlorohydrate, an aluminum-zirconium pentachlorohydrate or an aluminum-zirconium octachlorohydrate; or is chosen from a glycine-aluminum chlorohydrate-zirconium complex, preferably of aluminum-zirconium trichlorohydrex glycine, of aluminum zirconium tetrachlorohydrex glycine, of aluminum zirconium pentachlorohydrex glycine, of aluminum octachlorohydrex glycine -zirconium, or is chosen from sodium-aluminum chlorohydroxyacetate, aluminum hydrobromide or aluminum chloride. Other preferred antiperspirant active principles are chosen from aluminum hydrochloride, in particular aluminum hydrochloride corresponding to the general formula [A1 2 (OH) 5 C1 1-6 H 2 0] n , preferably [ A1 2 (OH) 5 C1 2-3 H 2 0] n , which may be present in non-activated or activated (depolymerized) form, as well as the aluminum hydrochloride corresponding to the general formula [A1 2 (OH) 4 C1 2 . 1-6 H 2 O] n , preferably [A1 2 (OH) 4 C1 2 2-3 H 2 O] n , which may be present in non-activated or activated (depolymerized) form. Examples of commercially available products are those of the AAZG series from Summit Reheis, in particular Aluminum Zirconium Pentachlorohydrex (AAZG 3108).
    The antiperspirant active ingredients which are particularly preferred according to the invention are chosen from the so-called "activated" aluminum salts, which are also called "enhanced activity" antiperspirant active ingredients (English: enhanced activity) ". Active ingredients of this type are known in the art and are also commercially available. Activated aluminum salts are generally obtained by heat treatment of a relatively dilute solution of the salt (for example, about 10% by weight of salt), aimed at increasing its surface ratio between peaks 4 and 3 in phase chromatography high performance liquid (HPLC). The activated salt can then be dried in powder form, in particular spray-dried. In addition to spray drying, cylinder drying, for example, is also suitable.
    The preferred antiperspirant active ingredients are mainly water-soluble substances. As preferably described in the present invention, the antiperspirant composition according to the invention must be substantially anhydrous. In polar solvents, the water-soluble antiperspirant active ingredients are largely insoluble. In this way, a high concentration of antiperspirant active ingredients can be effective on the skin: the antiperspirant active ingredient in the form of particles is applied to the skin during application, the water-soluble active ingredient then dissolving in sweat and then exerting its effect. Thanks to this mechanism, the antiperspirant effect is favored. According to the invention, the term “water-solubility” is understood to mean a solubility of at least 3% by weight at 20 ° C. - in other words, amounts of at least 3 g of the active antiperspirant substance are soluble in 97 g of water at 20 ° C. According to the invention, the term “water-solubility” is preferably understood to mean a solubility of at least 5% by weight at 20 ° C. - in other words, amounts of at least 5 g of the active antiperspirant substance are soluble in 95 g of water at 20 ° C.
    In the compositions according to the invention, 70 to 95% by weight of the particles have a size greater than 10 μm, 80 to 100% by weight of the particles have a size ranging up to 75 μm and 90 to 100% by weight of the particles have a size of up to 125 µm; most preferably, 75 to 80% by weight of the particles have a size greater than 10 µm, 90 to 100% by weight of the particles have a size of up to 75 µm and 99 to 100% by weight of the particles have a size up to 125 μm, respectively related to the weight of the active antiperspirant principle. By "size", in the case of spherical particles, is meant the diameter and in the case of particles of ellipsoid shape, the arithmetic mean of the longest to shortest axis, the lengths representing the projection under an optical microscope.
    According to another preferred embodiment of the present invention, the antiperspirant active principle (a) is present in the antiperspirant composition in an amount ranging from 5 to 40% by weight, preferably from 10 to 35% by weight, more preferably 15 to 30% by weight, most preferably 18 to 23% by weight, based on the total weight of the antiperspirant composition. The active ingredient has the best effects in these ranges of quantities.
    According to a preferred embodiment of the present invention, the antiperspirant composition d) at least one oil, preferably a silicone oil. Preferably, the silicone oil is chosen from octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, polydimethylsiloxane having mixtures of 10 and 10, viscosity 3 and mixtures, viscosity 3 and mixtures thereof, preferably chosen from mixtures of decamethylcyclopentasiloxane and dodecamethylcyclohexasiloxane, mixtures of hexamethyldisiloxane, octamethyltrisiloxane and decamethyltetrasiloxane, the silicone oil being, most preferably, chosen from decamethylcyclopentasiloxane.
    The viscosity of the polydimethylsiloxane is determined using a falling ball viscometer. With the help of this instrument, using DIN 53015, its viscosity can be determined. To facilitate the determination of the polysiloxanes which can be used as the second siloxane according to the invention in the cosmetic agent, the manufacturer's instructions relating to the viscosity of the polysiloxanes should be used. The polysiloxanes used are all commercially available and are generally classified according to their viscosities measured in Stokes.
    Preferred silicone oils can generally be chosen from dialkylet alkylarylsiloxanes which have a vapor pressure of less than 2.66 Pa (0.02 mm Hg) at 20 ° C and at an ambient pressure of 1013 hPa, such than octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane, dimethylpolysiloxane, low molecular weight phenyltrimethicone and methylphenylpolysiloxane, but also hexamethyldisiloxane, octamethyltrisiloxane and octamethyltrisiloxane In general, cyclic silicone oils are particularly preferred, such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane and dodecamethyl cyclohexasiloxane and mixtures thereof, such as those present for example in commercial products DC 244, 245, 344 and 345 from Dow Coming (vapor pressure at 20 ° C of about 13 to 15 Pa).
    Similarly, particularly preferred are linear silicone oils having from 2 to 10 siloxane units, in particular hexamethyldisiloxane (L 2 ), octamethyltrisiloxane (L 3 ), decamethyltetrasiloxane (L 4 ) as well as mixtures any two and three of L 2 , L 3 and / or L 4 , preferably mixtures such as those present in commercial products DC 2-1184, Dow Corning® 200 (0.65 cSt) and Dow Corning® 200 ( 1.5 cSt) from Dow Coming. Another preferred volatile silicone oil is a low molecular weight phenyltrimethicone having a vapor pressure at 20 ° C. of around 2000 Pa, such as that available from GE Bayer Silicones / Momentive under the name Baysilone Fluid PD 5.
    Silicone oils are carrier oils perfectly suited to the antiperspirant compositions according to the invention, because they combine a pleasant feeling on the skin and a low level of soiling of textiles. Advantageous silicone oils, however, have the disadvantage of low viscosity. In the case of dissociation of the antiperspirant composition, the problem of leaks is particularly important. The advantageous effect of the antiperspirant composition, which is caused by the use of rice starch with the hydrophobically modified clay mineral, in particular rice starch derived from the plant species Oryza sativa, with the Hydrophobically modified bentonite is particularly important when using preferred silicone oils.
    According to another preferred embodiment of the present invention, the oil (d) is present in the antiperspirant composition in an amount ranging from 40 to 95% by weight, preferably from 60 to 85% by weight , more preferably from 70 to 80% by weight, relative to the total weight of the antiperspirant composition. In particular, the silicone oil is present in the antiperspirant composition in an amount ranging from 40 to 95% by weight, preferably from 60 to 85% by weight, more preferably from 70 to 80% by weight, relative to the total weight of the antiperspirant composition.
    According to another preferred embodiment of the present invention, it contains e) a non-volatile oily component as an activator in the antiperspirant composition according to the invention, the non-volatile oily component having, under conditions standard (IUPAC, 2017 version), a vapor pressure below 10 Pa, preferably below 5 Pa at 20 ° C. More preferably, the non-volatile oily component (e) comprises glycerol or an organic carbonate, most preferably propylene carbonate.
    The non-volatile oily component - if it is present in the antiperspirant composition - is present in an amount ranging from 0.9 to 4% by weight, preferably in an amount ranging from 1 to 3% by weight, and most preferably from 1 to 2% by weight, based on the total weight of the antiperspirant composition.
    According to a preferred embodiment of the present invention, the antiperspirant composition is substantially anhydrous. By "substantially anhydrous" is meant according to the invention that the composition has a free water content of at most 7% by weight, based on the total weight of the antiperspirant composition. “Free water” is understood to mean, for the purposes of the present application, water which is not present in the antiperspirant composition in the form of water of crystallization, water of hydration or similar water bound to the molecular level.
    The water content of crystallization, water of hydration or similar water linked to the molecular level, present in the components used, in particular in the antiperspirant active ingredients, does not constitute free water in the sense of this application. Free water is for example water added to the composition according to the invention as a solvent, gel activator or solvent component for other active ingredients. The antiperspirant compositions according to the invention contain, based on their total weight, from 0 to 7% by weight of free water. The preferred antiperspirant compositions according to the invention contain, based on their total weight, from 0 to 6% by weight of free water, preferably from 0 to 5% by weight, particularly preferably from 0 to 4% by weight, most preferably 0 to 3% by weight of free water. The antiperspirant compositions according to the invention must therefore be considered to be substantially anhydrous.
    The preferred antiperspirant compositions according to the invention have a viscosity in the range from 1,000 to 3,500 mPa-s, particularly preferably from 1,500 to 3,000 mPa-s, most preferably from 2,000 to 2,500 MPa-s, respectively measured with a Brookfield viscometer at 23 ° C with a spindle 3 at a shear speed of 10 revolutions per minute.
    According to a preferred embodiment of the present invention, the antiperspirant composition comprises one or more aromatic substances or fragrances, also called perfume. For the purposes of this application, the definition of an aromatic substance corresponds to the definition commonly used by specialists in the field, as given in the Lexicon of chemistry of RÔMPP, ("Rômpp Lexikon Chemie", J. Falbe, M. Regitz (Hrsg.), 10th edition, Thieme-Verlag). In the context of the present invention, the fragrances or the aromatic substances which, based on the total weight of the antiperspirant composition, are present in an amount of less than 0.9% by weight in the anti-composition can only be considered as such. -transpirant and are completely soluble in the non-aqueous support, that is to say in oil.

    In addition, the compositions according to the invention may contain additional deodorizing agents. As deodorant agents, antimicrobial, antibacterial or germicidal substances, antioxidants or odor adsorbents can be used. Suitable antimicrobial, antibacterial or germicidal substances are in particular organohalogen compounds and organohalides, quaternary ammonium compounds, a number of plant extracts. Halogenated phenolic derivatives are preferred, such as, for example, hexachlorophene or Irgasan DP 300 (triclosan,
    2,4,4'-trichloro-2'-hydroxydiphenylether), 3,4,4'-trichloro-carbanilide, chlorhexidine (1, hexamethylene-bis- [5- (4-chlorophenyl)] - biguanide ), chlorhexidine gluconate, benzalkonium halides and cetylpyridinium chloride. In addition, sodium bicarbonate, sodium phenolsulfonate and zinc phenolsulfonate and, for example, the components of linden oil can be used. Less effective germicidal substances, but which act specifically against Gram-positive germs responsible for breaking down sweat, can also be used as deodorant agents. Benzyl alcohol can also be used as a deodorant. The other antibacterial deodorants are lantibiotics, glycoglycerolipids, sphingolipids (ceramides), sterols and other active substances which inhibit the adhesion of bacteria to the skin, such as glycosidases, lipases, proteases, carbohydrates, esters of di- and oligosaccharide fatty acids and alkylated mono- and oligosaccharides. The preferred deodorant active ingredients are long chain diols, for example
    1.2- alkane- (C 5 -Ci 8 ) -diols, glycerolmono- (C 8 -Ci 8 ) -esters of fatty acids or, more preferably, glycerolmono- (C 6 -Ci6) -alkyl ethers, in particular 2-ethylhexylglycerol ether, which are perfectly compatible with the skin and the mucous membranes and effective against bacteria of the genus Corynebacterium, as well as phenoxyethanol, phenoxyisopropanol (3-phenoxy-propan-2-ol), anisic alcohol, 2-methyl-5-phenyl-pentan-1-ol, 1,1-dimethyl-3-phenyl-propan-1-ol, benzyl alcohol, 2-phenylethan-1-ol, 3-phenylpropan l-ol, 4-phenylbutan-l-ol, 5-phenylpentan-l-ol, 2-benzylheptan-l-ol, 2,2-dimethyl-3-phenylpropan-l-ol,
    2.2- dimethyl-3- (3’-methylphenyl) -propan-l-ol, 2-ethyl-3-phenylpropan-l-ol,
    2- ethyl-3- (3’-methylphenyl) -propan-l-ol, 3- (3’-chlorphenyl) -2-ethylpropan-l-ol,
    3- (2'-chlorophenyl) -2-ethylpropan-l-ol, 3- (4'-chlorophenyl) -2-ethylpropan-l-ol, 3- (3 ', 4'-dichlorophenyl) -2- ethylpropan-1-ol, 2-ethyl-3- (2'-methylphenyl) -propan-1-ol, 2-ethyl-3- (4'-methylphenyl) -propan-1-ol, 3- ( 3 ', 4'-dimethylphenyl) -2-ethylpropan-1-ol, the
    2- ethyl-3- (4’-methoxyphenyl) -propan-l-ol, the
    3- (3 ’, 4’-dimethoxyphenyl) -2-ethylpropan-l-ol, 2-allyl-3-phenylpropan-l-ol and 2-n-pentyl-3-phenylpropan-l-ol. Chelating agents can also contribute to the deodorizing effect, by stably complexing the ions of catalytically oxidizing heavy metals (for example iron or copper). Suitable chelating agents are, for example, the salts of ethylenediamintetraacetic acid or nitrilotriacetic acid, as well as the salts of the acid
    -hydroxyethane-1,1 -diphosphonic.
    In addition, the invention was to provide a ball applicator with a lower tendency to leak.
