Description

The invention relates to a stick-deodorant (sweat pencil) or stick-antiperspirant (stick-antiperspirant) based on an oil-in-water dispersion / emulsion for applying water-soluble active ingredients to the skin.

Standard commercial deodorants and antiperspirants are mainly made in the form of sprays or sticks; also available in the form of ball applicators and creams. Many antiperspirant stick preparations are made as an anhydrous suspension stick. This type of preparation leaves behind a pleasant feeling of dryness on the skin of the consumer after application. However, the effective isolation of the active water-soluble antiperspirant components from such preparations is limited (reference: Chemistry and Technology for the Cosmetics and Toiletries Industry, publication by O.F. Williams and W. Schmitt, London: Blackie, 1996, second edition, p. 326) and in most cases, a sensation of freshness, valuable to many consumers, is not achieved. Anhydrous preparations, in particular preparations based on volatile silicone oil, have the disadvantage that dispersed active ingredients easily lead to visible traces of the product on the skin and clothing. In addition, such preparations are relatively more expensive since oily components are more expensive as carriers of active ingredients than water. Compression during application often leads to loss of oil, which reduces the cosmetic value of these drugs to the consumer.

Compared to anhydrous sticks, which are known, for example, from international applications WO 94/24997 A1 and WO 00/67713 A1, emulsion sticks, which are disclosed, for example, in international application WO 98/17238 A1, European patent application EP 281288 A2 , German application DE 2335549, US patent US 4,725,431, European patent applications EP 617952 A1 and EP 291334, have several advantages. Replacing wax and oil components with water makes emulsion sticks more cost-effective to manufacture. Emulsified waxes give a feeling of softness and tenderness on the skin, and, in the end, water-soluble active ingredients of a cosmetic product (i.e., in particular the active ingredients of an antiperspirant) can be more easily excreted on the skin, since they are already present in dissolved form in the aqueous phase emulsions.

International application WO 02/017870 A2 discloses antiperspirant sticks without a water-oil emulsifier or high melting wax, which contain siliconized polyamide as a regulator of consistency or structural component. In accordance with the first claim of European application WO 02/017870 A2, the aqueous phase forms an internal phase, i.e. a dispersed phase, and the claimed gels are water-in-oil emulsions.

WO 02/032914 A1 discloses, with respect to several illustrative embodiments, water-based antiperspirant sticks based on a water-in-oil emulsion that contain acylated cellobiose as a consistency regulator or structural component and contain a high proportion of silicone and hydrocarbon oils that are unfavorable in accordance with the invention, and moreover, do not contain emulsifiers such as oil-in-water or high melting wax.

Since the emulsion sticks of the prior art are made on the basis of a water-in-oil dispersion / emulsion, the water-soluble active ingredients are in the internal, dispersed phase and, after application, must first migrate through the external, lipophilic layer in order to reach their application site action on the skin. Known sticks based on a water-in-oil emulsion thus have disadvantages that are similar to the disadvantages of sticks based on anhydrous suspensions with respect to the availability of the active ingredient.

German application DE 19749819 A1 discloses water-containing and oil-containing, wax-free antiperspirant sticks based on an oil-in-water emulsion. Sticks of this type have properties that do not meet the requirements of a cosmetic product, leave behind unpleasant sticky and visible traces and exhibit resistance that is insufficient for prolonged use. One sample with glycerol monostearate as a B / M emulsifier and octnldodecanol as an oil component has a medium hard consistency and an oily feel on the skin and softens only at 50 ° C.

International application WO 99/59537 A1 discloses water-containing cosmetic sticks that contain wax components with a melting point> 50 ° C, non-ionic water-in-oil emulsifiers, non-ionic oil-in-water emulsifiers, with a HLB hydrophilic-lipophilic balance value greater than than 7, and polyol. Some sticks contain oils that are liquids at 25 ° C, but which, instead of being included at the beginning of the emulsion formation process, as in the sticks of this application, are mixed as a pre-emulsified concentrate, for example a microemulsion or PIT emulsion, during the cooling phase of the stick mass at a temperature of 55 ° C. This type of production is necessary so as not to endanger or even destroy the stability of the dispersion system of lipid or wax crystals. Sticks of this type also have properties that do not meet the requirements of a cosmetic product, can leave unpleasant sticky and visible traces, and show resistance that does not meet the requirements of long-term use.

International application WO 02/083091 A1 discloses structural antiperspirant compositions in the form of microemulsions, which are an oil-in-water microemulsion or a water-in-oil microemulsion or a continuous phase on both sides depending on the type and amount of surfactants, but in which continuous both The hand phase is universally prevailing. Transparent microemulsions condense with an oil-soluble or oil-dispersed “structurant”. The oil-soluble or oil-dispersed structurant is selected from esters or amides of 12-hydroxystearic acid, esters and amides of di- and tricarboxylic acids, sterols, sterol esters such as oryzanol, cellobionic fatty acid esters, sugar esters such as acylated maltose and oil phase condensing agents, which are transversely unbound oil-soluble and oil-dispersed polymers, such as the commercial product Kraton G. Ionic emulsifiers with a hydrophobic value silo-lipophilic balance (HLB) 2-15, preferably with a hydrophilic-lipophilic balance of HLB up to 12 are also included. Polyols are disclosed as possible, but optional components. This source does not disclose the possible values of the solubility parameters of B / M type emulsifiers and oil components selected for each other. The structural differences between these compositions and sticks based on the oil-in-water dispersion / emulsion of the present invention, which are not microemulsions, become especially clear due to the high proportion, namely 19% -66% by weight, relative to the total composition of silicone and (paraffin) hydrocarbon oils, which all illustrative embodiments of the invention disclose, but which are not favorable in accordance with the invention.

Published German patent applications DE 19962878 A1 and DE 19962881 A1 disclose cream-shaped deodorants or antiperspirants based on an oil-in-water emulsion that have a viscosity of at least 50,000 mP at 21 ° C., preferably in the range of 200,000- 1,500.00 MP, that is, they have a viscous to very viscous form. These creams contain wax components with a melting point> 50 ° C, non-ionic water-in-oil emulsifiers, but simple ethylene glycol esters or pentaerythryl esters, non-ionic oil-in-water emulsifiers, with a HLB hydrophilic-lipophilic balance value greater than 7 , and polyol. Being soft creams, they can be applied either using only fingers, which is considered impractical by many consumers, or by pouring the cream into special applicators, which is much more expensive than the stick coat of the deodorant or antiperspirant of the present invention. If, after heating and mixing, the compositions disclosed in the German patent applications DE 19962878 A1 and DE 19962881 A1 were statically cooled, i.e. without stirring, stick-like compositions would be obtained which would have completely unfavorable application properties, such as low heptics and / or insufficient resistance, for example, as a result of phase separation or the formation of aqueous condensate, since emulsifiers and oils are not consistent with each other, as in this invention.

The previously unpublished German patent application DE 102004036689.6 discloses stick-deodorants or stick-antiperspirants in the form of an oil-in-water dispersion containing at least a lipid or oil component with a melting point> 50 ° C, at least one non-ionic an oil-in-water emulsifier with an HLB hydrophilic-lipophilic balance value above 7 within the system of non-ionic oil-in-water emulsifiers with an average HLB hydrophilic-lipophilic balance between 10 and 19; as a consistency regulator and / or water-binding component, at least one non-ionic water-in-oil emulsifier with a HLB hydrophilic-lipophilic balance value of greater than 1.0 and less than / equal to 7.0, which can form liquid crystal structures only with water or with water in the presence of a hydrophilic emulsifier, and at least one oil that is liquid at a temperature of 20 ° C and is not an aroma component or an essential oil, with the maximum deviation between the (average) solubility parameter vs x oil components and (average) solubility parameter of the emulsifier of water-in-oil emulsifiers is or -0.7 (cal / cm ^{3) 0.5} or +0.7 (cal / cm ^{3) 0.5} in the presence of linear saturated fatty alcohol as emulsifier type water-in-oil or part of a water-in-oil emulsifier, respectively, and -0.4 (cal / cm ³ ) ^0.5 or +0.7 (cal / cm ³ ) ^0.5 in the presence of water-in-oil emulsifiers different from linear saturated fatty alcohols, in the absence of linear saturated fatty alcohols as a water-in-oil emulsifier, respectively; at least one water-soluble polyhydroxy-C ₂ -C ₉ alkanol with 2-6 hydroxyl groups and / or at least one water-soluble polyethylene glycol with 3-20 units of ethylene oxide; from 5% to less than 50% by weight of water in relation to the total composition; and at least one deodorizing or antiperspirant agent; where the stick shows a penetration force in the range of 200 to 600 gram-force (g-force) at a depth of 5.000 mm (five millimeters) and a maximum electrical resistance of 300 kOhm (kilo-ohm). It has been discovered, however, that glycerol monostearate and glycerol distearate, the preferred B / M emulsifiers described in German Patent Application DE 10 2004 036 689.6, may present difficulties in large-scale production, especially with regard to consistency.

Therefore, the aim was to develop a deodorant or antiperspirant composition that is suitable as an effective carrier of water-soluble active ingredients and makes it possible to quickly release the active ingredients to the skin.

The next goal was to develop a deodorant or antiperspirant composition with excellent cosmetic care properties.

The next goal was to develop sticks in the form of a deodorant or antiperspirant, which, on the one hand, would have high stability, i.e. hardness, but on the other hand, which would be nice to apply, that is, not too hard, but could be easily distributed on the skin and at the same time allocate the appropriate amount of product.

The next goal was to develop a deodorant or antiperspirant composition that, when applied to the skin, leaves traces of as little as possible sticky and less visible.

The next goal was to develop a deodorant or antiperspirant composition that, when applied to the skin, leaves optimally small visible marks on clothing that is in contact with the treated skin.

The next goal was to develop a deodorant or antiperspirant composition that could be easily washed off the skin.

The next goal was to develop a deodorant or antiperspirant composition with a coefficient of economic efficiency, which is favorable from an economic point of view, based on application.

The next goal was to develop a deodorant or antiperspirant composition that allowed the mass production of persistent deodorant sticks or antiperspirant sticks with a suitable consistency.

Surprisingly and unexpectedly for those skilled in the art, these goals were achieved with a stick-deodorant or stick-antiperspirant in the form of an oil-in-water dispersion / emulsion containing

a) at least one lipid or wax component with a melting point> 50 ° C, which does not include components b) or c),

b) at least one non-ionic oil-in-water emulsifier with an HLB hydrophilic-lipophilic balance value greater than 7 inside a mixture of oil-in-water emulsifiers with an average HLB hydrophilic-lipophilic balance in the range of 10-19,

c) at least one non-ionic water-in-oil emulsifier with a HLB hydrophilic-lipophilic balance value of greater than 1.0 and less than 7.0, selected from among monoesters and diesters of ethylene glycol and mono-, di-, tri- and tetra- pentaerythritol esters with linear saturated and unsaturated fatty acids having 12-30, but especially 14-22 carbon atoms that can be hydroxylated, and mixtures thereof as a regulator of the consistency and / or component of water binding;

d) at least one oil, which is in the form of a liquid at 20 ° C and is not an aroma component or an essential oil at which the maximum deviation of the (average) solubility parameter of all oil components is d) and the (average) solubility parameter of the water-emulsifier in oil or emulsifiers is -0.7 (cal / cm ³ ) ^0.5 or +0.7 (cal / cm ³ ) ^0.5, respectively, in the presence of a linear saturated fatty alcohol with a chain length of at least 8 carbon atoms, and -0.4 (cal / cm ^{3) 0.5} or +0.7 (cal / cm ^{3) 0.5,} respectively, in the presence of emulsifiers of type ode-in-oil non-linear saturated fatty alcohols with a chain length of at least 8 carbon atoms, wherein the linear saturated fatty alcohols with a chain length of at least 8 carbon atoms are absent;

e) at least one water-soluble polyhydroxy-C ₂ -C ₉ alkanol with 2-6 hydroxyl groups and / or at least one water-soluble polyethylene glycol with 3-20 units of ethylene oxide;

f) from 5% to less than 50% by weight of water relative to the total composition;

g) at least one deodorant or antiperspirant active ingredient.

The lipid or wax component with a melting point> 50 ° C forms a gel matrix with oil (oils) and optionally additionally with highly melting lipid or wax components; this gel matrix can absorb a large amount of water and polyols. These structures, which are stabilized by a certain amount of water-in-oil emulsifiers and oil-in-water emulsifiers, leave a fresh, cooling sensation after application due to the water content in them. Here, the emulsifiers are matched to each other so that the stick compositions according to the invention are present in the form of an oil-in-water dispersion / emulsion. The stick compositions of the invention are thus not present as a microemulsion. In order to produce stick compositions of the invention, the aqueous phase and the oil phase must be heated to at least 70 ° C and mixed together or homogenized while hot, i.e. at least at 70 ° C, in order to reach emulsion structure of the invention. A manufacturing method similar to that disclosed in US Pat. No. 4,205,062 (e.g., mixing the oily and aqueous phases at 65 ° C.) does not meet the requirements for a homogeneous stick composition based on an oil-in-water dispersion / emulsion. Not wanting to be bound by this theory, it is believed that oil-in-water emulsifiers, along with some water-in-oil emulsifiers, form laminar liquid crystal phases, which are transferred by some water to the gel hydrophilic phase. This hydrophilic gel phase surrounds the bulk of the aqueous phase. The lipophilic components are, in turn, dispersed within this aqueous bulk phase, surrounded by a lipophilic gel phase, which is formed by water-in-oil emulsifiers with some oil-in-water emulsifiers and with some water.

The active antiperspirant ingredient is dissolved in an external, continuous aqueous phase, resulting in significantly improved and more efficient release of the ingredient compared to known anhydrous suspension sticks and sticks based on a water-in-oil emulsion. The basis in the form of an M / B emulsion of the stick compositions of the invention leads to a significantly improved and more efficient release of the ingredient compared to the known anhydrous suspension sticks and sticks based on a water-in-oil emulsion. The release of the active component can very easily be indirectly determined by measuring the electrical resistance of a particular product. Measuring the electrical resistance of such compositions is also an appropriate way to distinguish between an oil-in-water system and a water-in-oil system. The oil-in-water system exhibits high electrical conductivity and therefore a correspondingly low electrical resistance due to the continuous aqueous phase. The exact organization of the measurement and the measurement procedure are described below (see below). The sticks of the present invention therefore have an electrical resistance of at most 300 kOhm, preferably at most 100 kOhm, and particularly preferably at most 80 kOhm. In contrast, the sticks disclosed in WO 98/17238 A1 exhibit an electrical resistance of more than 3,000 kΩ; therefore, they obviously use a water-in-oil system.

The solidification of deodorant sticks or antiperspirant sticks according to the invention does not occur on the basis of soap gels or gels of fatty acid salts, and fatty acids are alkanoic, alkenic and alkynic acids having at least 4 carbon atoms which may be substituted , for example, hydroxyl groups. In a particularly preferred embodiment, the deodorant sticks or antiperspirant sticks according to the invention do not contain gels based on soaps or gels based on fatty acid salts, in particular free of lithium, sodium, potassium, ammonium, diethanolamine and triethanolamine fatty acid salts . Soap-based sticks are not compatible with the acidic active ingredients of an antiperspirant such as those used in the antiperspirant sticks of the invention.

The curing of deodorant sticks or antiperspirant sticks according to the invention does not occur on the basis of inorganic and / or organic polymer hydrogel formers, such as celluloses, cellulose derivatives, for example, hydroxyalkyl celluloses, polyacrylates, wigum or bentonites. In a particularly preferred embodiment, the deodorant sticks or antiperspirant sticks of the invention are free of gels formed by inorganic and / or organic polymer hydrogel formers.

In addition to favorably isolating the active ingredient, an oil-in-water dispersion / emulsion composition has the following advantages. The first composition can be easily removed from the skin. The second, during or after application to the skin, an oil-in-water therapeutic cream is formed along with skin moisture.

Surprisingly and unexpectedly for those skilled in the art, it was found that the oil components and a water-in-oil emulsifier or a mixture of water-in-oil emulsifiers should be suitable for each other with respect to their solubility parameters in order to form stick compositions with satisfactory hardnesses related with operational indicators. To determine the solubility parameter in the meaning of this invention, reference is made to the publication "Solubility - effects in the product, packaging, penetration and preservation", cited by K. Waughhan in "Cosmetics and Toiletries", Volume 103, October, 1988, p. 47- 69. The values of the solubility parameters published there are given in (cal / cm ³ ) ^0.5 , which are not SI units. For convenience, this non-SI unit will be supported in this specification. Values can be easily translated based on a ratio of 1 cal = 4.1860 J.

A number of solubility parameters tabulated by Wauhan in the publication “Cosmetics and Toiletries”, Volume 103, October 1988, pp. 47-69, were calculated in accordance with the Hildebrand equation (see K. Wauhan: J, Soc. Cosmet Chem., Vol. 36, pp. 319-333 (September / October, 1985) and the Hildebrand equation given therein, and J. Am. Chem. Soc., Vol. 38, pp. 1442-1473 (1916) and J. Hildebrand and R. Scott: Solubility of Non-Electrolytes, Third Edition, Reinhold Publ. Corp., New York, 1949); they are summarized below. Waughkhan mentions that solubility parameters can be calculated not only by using the Hildebran equation, but also, for example, based on the enthalpy of evaporation (Scatchard, J. Am. Chem. Soc., Vol. 38, p. 321 (1916)). All calculation methods can give different solubility parameters, especially if the chemical has an acidic or basic function.

In this invention, it is preferable that the coordination of solubility parameters, oil components and a water-in-oil emulsifier or mixtures of water-in-oil emulsifiers is performed only for the solubility parameter values that have been determined using the same methods. It is especially preferable when the values of the solubility parameter, which were determined using the Hildebrand equation ((see K.D. Waughhan: J. Soc. Cosmet. Chem., Volume 36, p. 319-333 (September / October, 1985)), If there are no available pairs of solubility parameter values that were determined using the same method, it is also possible to apply values that were determined by different methods for the particular combination of the oil component and the water-in-oil emulsifier. even an experimental method However, this is a less preferred option according to the invention (see Table 1).

In the stick compositions of the invention, the (average) integrity solubility parameter of the oils present in the presence of linear saturated fatty alcohols having a chain length of at least 8 carbon atoms deviates, at most, by -0.7 (cal / cm ³ ) ^0.5 or , the largest, at +0.7 (cal / cm ³ ) ^0.5 , preferably the largest, at -0.6 (cal / cm ³ ) ^0.5 or, the largest, at +0.6 (cal / cm ³ ) ^{0, 5} , particularly preferably, the largest, at -0.4 (cal / cm ³ ) ^0.5 or, at most, at +0.5 (cal / cm ³ ) ^0.5 , and in the presence of water-in-oil emulsifiers, which differ from linear saturated fatty alcohols with a chain length of at least 8 carbon atoms, and linear saturated fatty alcohols with a chain length of at least 8 carbon atoms are absent, at most -0.4 (cal / cm ³ ) ^{0 , 5} or, the largest, at +0.7 (cal / cm ³ ) ^0.5 , preferably the largest, at -0.3 (cal / cm ³ ) ^0.5 or, the largest, at +0.6 (cal / cm ³⁾ ) ^0.5 , particularly preferably, the largest, at -0.2 (cal / cm ³ ) ^0.5 or, at most, at +0.5 (cal / cm ³ ) ^0.5 , of the (average) solubility parameter of the emulsifier (s ) type water-in-oil. If mixtures of water-in-oil emulsifiers or oil mixtures are used, then in each case the average solubility parameter of the mixture is considered, in particular the arithmetic average in accordance with the weight fractions of the individual components. In the framework of this invention, it is also possible that the fraction containing up to 20% by weight of oily components that are in a liquid state at 20 ° C, consist of oils whose solubility parameters deviate by more than -0.4 or -0.7 (cal / cm ³ ) ^0.5 or more than +0.7 (cal / cm ³ ) ^0.5, respectively, of the (average) solubility parameter of the emulsifier (emulsifier mixtures) of the water-in-oil type. In a particularly preferred embodiment, there are no oils that are liquid 20 ° C and whose solubility parameter deviates by more than ± 1.0 (cal / cm ³ ) ^0.5 , preferably more than ± 0.7 (cal / cm ³ ) ^0.5 and, particularly preferably, ± 0.5 (cal / cm ³ ) ^0.5 of the (average) solubility parameter of a water-in-oil emulsifier / water-in-oil emulsifiers.

Lipid or Wax Matrix

The lipid or wax matrix of the stick compositions according to the invention includes at least one lipid or wax component with a melting point> 50 ° C, which is not included in non-ionic oil-in-water emulsifiers with a hydrophilic-lipophilic balance HLB greater than than 7, or non-ionic water-in-oil emulsifiers, with a HLB hydrophilic-lipophilic balance value greater than 1.0 and less than or equal to 7.0.

In general, waxes have a hard to brittle consistency, are coarse to finely crystalline, transparent to opaque, but not glassy, and melt at temperatures above 50 ° C without breaking. Only at temperatures slightly above the melting point do they have a low viscosity and exhibit a high degree of temperature-dependent consistency and solubility.

In accordance with the invention, preference is given, for example, to natural plant waxes, for example, candelilla wax, carnauba wax, vegetable wax, sugarcane wax, attalea wax, cork tree bark wax, sunflower wax, fruit waxes such as orange waxes, lemon waxes, grapefruit wax, and animal waxes such as beeswax, shellac wax and spermaceti. For the purposes of the invention, it is particularly preferable to use hydrogenated or hardened waxes. Chemically modified waxes, in particular hard waxes such as, for example, montan wax esters, hydrogenated jojoba waxes and sasol waxes can also be used as a wax component. Synthetic waxes which are also preferred in accordance with the invention include, for example, polyalkylene waxes and polyethylene glycol waxes, C ₂₀ -C ₄₀ dialkyl esters of dimeric acids, C ₃₀ -C ₅₀ alkyl beeswax and alkyl and alkylaryl dimeric fatty acid esters.

A particularly preferred waxy component is selected from at least one ester of saturated monohydroxy-C ₁₆ -C ₆₀ alcohol and saturated C ₈ -C ₃₆ monocarboxylic acid. In accordance with the invention also include lactides, cyclic double esters of α-hydroxycarboxylic acids of the corresponding chain length. The esters of fatty acids and long chain alcohols have already proved to be of particular benefit to the composition according to the invention, due to their excellent sensory properties, important in the preparation of antiperspirant and high stability, important for the whole stick. Esters consist of saturated, branched or unbranched monocarboxylic acids and saturated, branched or unbranched monohydroxy alcohols. In accordance with the invention, it is also possible to use esters of aromatic carboxylic acids or hydroxycarboxylic acids (for example, 12-hydroxystearic acid) and saturated, branched or unbranched alcohols, if the wax component has a melting point> 50 ° C. It is particularly preferable to select wax components from the group of esters of saturated, branched or unbranched alkane carboxylic acids with a chain length of 12 to 24 carbon atoms, and saturated, branched or unbranched alcohols with a chain length of 16 to 50 carbon atoms that have a melting point> 50 ° FROM.

In particular, C _16-36 alkyl stearates and C _18-38 alkyl hydroxystearoyl stearates, C _20-40 alkyl erucates and cetearyl behenates may be beneficial as a wax component. Wax or wax components have a melting point> 50 ° C, preferably> 60 ° C.

A particularly preferred embodiment of the invention contains C ₂₀ -C ₄₀ alkyl stearates as a wax component. This ester is known as Kesterwachs® K82H or Kesterwachs® K80H and is sold by Koster Keunen. It is a synthetic imitation of the fraction of beeswax monoester and is characterized by its hardness, ability to form gels from oils and its wide compatibility with lipid components. This wax can be used as a stabilizer and as a consistency regulator for B / M and M / B emulsions. Kesterwachs offers the advantage that even at low concentrations, it has an excellent ability to gel from oil and thus does not make the stick mass too heavy and allows it to be released evenly. A further particularly preferred embodiment of the invention comprises cetearyl behenate, i.e. a mixture of cetyl behenate and stearyl behenate as a wax component. This ester is known as Kesterwachs® K62 and is sold by Koster Keunen.

In addition, preferred lipid or wax components with a melting point> 50 ° C are triglycerides of saturated and optionally hydroxylated C _12-30 fatty acids, such as hardened triglyceride fats (hydrogenated palm oil, hydrogenated coconut oil, hydrogenated castor oil), glyceryl tribe tribgenin) or glyceryl tri-12-hydroxystearate, also synthetic full esters of fatty acids and glycols or polyols having 2-6 carbon atoms, provided that they have the melting point is> 50 ° C, for example, preferably a triglyceride of C ₁₈ -C ₃₆ acid (Syncrowax® HGL C).

In accordance with the invention, hydrogenated castor oil, available, for example, as a commercial Cutina® HR product, is particularly preferred as a wax component.

In addition, saturated lipid or wax components with a melting point> 50 ° C are saturated linear C ₁₄ -C ₃₆ carboxylic acids, in particular myristic acid, palmitic acid, stearic acid and behenic acid, and mixtures of these compounds, for example Syncrowax® AW 1C (C ₁₈ -C ₃₆ fatty acids) or Cutina® PS 45 (palmitic and stearic acids).

Preferred deodorant sticks and antiperspirant sticks according to the invention are characterized in that the lipid or wax component a) is selected from esters of saturated monohydroxy-C ₁₆ -C ₆₀ alkanol and saturated C ₈ -C ₃₆ monocarboxylic acid, in particular cetyl behenate, stearyl behenate and C ₂₀ -C ₄₀ alkyl stearate, glycerol triesters and saturated linear C ₁₂ -C ₃₀ carboxylic acids that can be hydroxylated, Candelian wax, carnauba wax, beeswax, saturated linear C ₁₄ -C ₃₆ -ka slick acids, and mixtures of the aforementioned substances. Particularly preferred mixtures of lipid and wax components a) are selected from mixtures of cetyl behenate, stearyl behenate, hardened castor oil, palmitic acid and stearic acid. In addition, preferred mixtures of lipid and wax components a) are selected from mixtures of C ₂₀ -C ₄₀ alkyl stearate, hardened castor oil, palmitic acid and stearic acid.

In addition, preferred deodorant sticks or antiperspirant sticks in accordance with the invention are characterized in that the total amount of lipid and wax component (s) a) is 4-20% by weight, preferably 8-15% by weight with respect to the whole composition .

The stick compositions according to the invention include at least one non-ionic oil-in-water emulsifier with a hydrophilic-lipophilic balance HLB greater than 7. These emulsifiers are generally known to those skilled in the art, for example, in " Encyclopedia of Chemical Technology, "Kirk-Otmer, Third Edition, 1979, Volume 8, pp. 913-916. For ethoxylated products, the hydrophilic-lipophilic balance of HLB is calculated in accordance with the formula HLB = (100-L): 5, where L is the weight of the fraction of lipophilic groups, i.e., fatty alkyl and fatty acyl groups, in ethylene oxide addition products, expressed as a percentage by weight.

When selecting non-ionic oil-in-water emulsifiers that are suitable in accordance with the invention, it is particularly preferable to use a mixture of non-ionic oil-in-water emulsifiers in order to optimally adjust the stability of the stick compositions in accordance with the invention.

Here, the individual emulsifier components contribute to the total value of the hydrophilic-lipophilic balance of HLB or the average value of the hydrophilic-lipophilic balance of HLB of a mixture of oil-in-water emulsifiers in accordance with the proportion of their amount to the total number of oil-in-water emulsifiers. According to the invention, the average hydrophilic-lipophilic balance of the HLB mixture of oil-in-water emulsifiers is 10-19, preferably 12-18 and particularly preferably 14-17. In order to achieve such an average value of the hydrophilic-lipophilic balance of HLB, oil-in-water emulsifiers with a hydrophilic-lipophilic balance of HLB from intervals 10-14, 14-16 and, optionally, 16-19 are preferably combined with each other. Mixtures of oil-in-water emulsifiers can of course also contain non-ionic emulsifiers with a hydrophilic-lipophilic balance of HLB in the range of> 7-10 and 19-20; such emulsifier mixtures may also be preferred in accordance with the invention. However, in another preferred embodiment, deodorant sticks or antiperspirant sticks according to the invention may also contain only one oil-in-water emulsifier, with an HLB hydrophilic-lipophilic balance value in the range of 10-19.

Preferred deodorant sticks or antiperspirant sticks according to the invention are characterized in that the non-ionic oil-in-water emulsifier b) is selected from ethoxylated C ₈ -C ₂₄ alkanols with an average of 10-100 molar ethylene oxide per mole ethoxylated With ₈ -C ₂₄ -carboxylic acids with an average of 10-100 mol of ethylene oxide per mole, silicone copolyols with units of ethylene oxide or with units of ethylene oxide and propylene oxide, alkyl mono- and oligoglycosides having 8-22 carbon atoms in the alkyl part, and their ethoxylated ana dens, ethoxylated sterols, partial polyglycerol esters with 2-10 units of glycerol and esterified with 1-4 groups of saturated or unsaturated, linear or branched, optionally hydroxylated C ₈ -C ₃₀ fatty acids, provided that they have a hydrophilic-lipophilic balance value HLB is greater than 7, and mixtures of the above compounds.

The ethoxylated C _8-24 alkanols have the formula R ¹ O (CH ₂ CH ₂ O) _n H, where R ¹ is a linear or branched alkyl and / or alkenyl group having 8-24 carbon atoms and n, the average number of units of ethylene oxide per 1 molecule, denotes 10-100, preferably 10-30 moles of ethylene oxide per 1 mol of caprylic alcohol, 2-ethylhexyl alcohol, capric alcohol, lauryl alcohol, isotridecyl alcohol, myristyl alcohol, cetyl alcohol, palmitoleyl alcohol, stearyl alcohol, isostearyl alcohol , oleyl alcohol, elaidil sp mouth petroselinilovogo alcohol (petroselinyl alcohol), arachidic alcohol, gadoleilovogo alcohol, behenyl alcohol, erucyl alcohol and brassidyl alcohol (brassidyl alcohol) and technical grade mixtures thereof.

With respect to the glycoside group, both monoglycosides in which the cyclic sugar group is linked by a glycosidic bond with a fatty alcohol, and also oligomeric glycosides with an oligomerization degree of up to about 8, but preferably 1-2, are suitable. The degree of oligomerization here is the average value, which is based on the distribution of homologues, which is common for such industrial products. Products available under the Plantacare® brand name contain a glycosidic linked C ₈ -C ₁₆ -alkyl group on the oligoglycoside group, whose average degree of oligomerization is 1-2, preferably 1.2-1.4.

The following table contains various oil-in-water emulsifiers and water-in-oil emulsifiers, and their hydrophilic-lipophilic balance HLB values. The hydrophilic-lipophilic HLB balance values, however, can also be calculated using the Griffin method, as, for example, in ROMPP Chemic Lexikon, especially the online version of November 2003. (November, 2003), and the Fiedler, Kirk-Otmer and Janistin handbook under the keyword "HLB System." As long as there is a contradiction between the hydrophilic-lipophilic balance of HLB substances found in the literature, the values of the hydrophilic-lipophilic balance of HLB, which become the closest to the values of the hydrophilic-lipophilic balance of HLB according to the Griffin method, should be used to represent the invention. If the clear value of the hydrophilic-lipophilic balance of HLB cannot be determined in this way, the value of the hydrophilic-lipophilic balance of HLB established by the emulsifier manufacturer should be used to present the invention. If this is also not possible, then the value of the hydrophilic-lipophilic balance of HLB is determined experimentally.

HLB hydrophilic-lipophilic balance values and chemical designation (from H. Janistyn, Handbuch der Kosmetika und Riechstoffe, Huthig Verlag Heidelberg, 3rd edition, 1978, volume 1, p. 470 and volume 3, p. 68-78) are given below:

Fragrances

Particularly preferred deodorant sticks or antiperspirant sticks according to the invention are those which additionally contain a flavoring component. As components of perfumery products that add aroma, aromatic oils or components of aromatic oils can be used. Aromatic oils of corresponding aromas may be, in the context of the invention, individual aromatic compounds, for example synthetic products of the ester, aldehyde, ketone, alcohol and hydrocarbon ester class. Aromatic compounds of the ester class are, for example, benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate (DMBCA), phenylethyl acetate, benzyl acetate, ethylmethyl phenyl cyclate, alkyl cyclohexylpropyl phosphate, alkylcyclohexylpropyl phosphate, alkylcyclohexylpropyl phosphate, alkylcyclohexyl cyclate, (melusate) and jasmecyclate (jasmecyclate). Among the esters are, for example, benzylethyl ether and ambroxan, among the aldehydes, for example, linear alkanols with 8-18 carbon atoms, citral, citronellal, citronyloxyacetaldehyde, cyclamenaldehyde, lilial and bourgeonal, among ketones, for example, ionones, alpha isomethylionone, and methylcetyl ketone, among the alcohols anethol, citronellol, eugenol, geraniol, linalul, phenylethyl alcohol and terpineol, including hydrocarbons, primarily terpenes such as lemons and pines. Preferably, mixtures of various aromatic substances are used which constitute a suitable aroma mixture.

Such aromatic oils may also contain mixtures of natural aromatic substances, such as are available from plant sources, for example, pine, citrus, jasmine, patchouli, rose or ylang-ylanga oil. Muscat butter, chamomile oil, clove oil, medicinal lemon balm oil, peppermint oil, cinnamon leaf oil, linden flower oil, juniper oil, vetiver oil, frankincense oil, galbanum oil, labdanum oil, as well as oil from orange blossom, neroli oil, orange peel oil and sandalwood oil.

In order to be sensory, aromatic substances must be volatile, in accordance with which, along with the nature of the functional groups and structure of the chemical compound, the molar mass also plays an important role. For this reason, most aromatic substances have a molar mass of up to 200 Da, while a molar mass of 300 Da and above is more an exception. Based on the various volatilization of aromatic substances, the perfume aroma corresponding to an aroma composed of several aromatic substances changes during the evaporation process, whereby the aroma sensation is divided into the “upper note”, “middle note corresponding to the body of the aroma” and “final note” corresponding to drying. " Since sensory perception depends to a large extent on the intensity of the smell, the top note of the perfume product corresponding to the aroma does not consist solely of volatile compounds, while the final note consists of most of the less volatile, i.e. more stable aromatic substances. In the composition of a perfumery product, more easily evaporating aromatic substances can be associated, for example, with certain fixatives, with the help of which their too rapid evaporation is blocked. The subsequent classification of aromatic substances in the “lighter evaporation” corresponding to the “stability” of aromatic substances does not say anything about the sensation of smell and whether aromatic substances are perceived as an upper or middle note.

Persistent aromatic substances that are applicable in the context of this invention are, for example, ether-forming oils such as angelica oil, anise oil, arnica flower oil, basil oil, laurel oil, bergamot oil, champaka flower oil, fir oil , turpentine oil, elemi tree oil, eucalyptus oil, fennel oil, pine oil, galbanum oil, geranium oil, ginger herb oil, guaiac oil, guryun balm, immortelle oil / chasteweed, Ho oil, ginger aslo, iris oil, cayeput oil, essential oil, chamomile oil, camphor oil, ylang-ylang flower oil, cardamom oil, Chinese cinnamon oil, spruce cone oil, copa balm, coriander oil, peppermint oil, caraway oil, caraway oil, lavender oil, lemongrass oil, lime oil, tangerine oil, lemon balm oil, amber oil, myrrh oil, clove oil, neroli oil, Naioli oil, oliban oil, orange oil, various kinds of oregano oil, palmmarose oil, patchouli oil, miroxy oil bosom, fusel oil, peppermint oil, capsicum oil (red) pepper, pine oil, rose oil, rosemary oil, sandalwood oil, celery oil, lavender oil, star anise anise oil, turpentine oil, thuja oil, thyme oil, verbena oil, vetiver oil, juniper oil, wormwood oil, winter green oil, ylang-ylang oil, hyssop oil, cinnamon oil, cinnamon leaf oil, Canadian collinsonia oil, lemon oil and cypress oil.

But also less volatile, respectively solid aromatic substances of natural or synthetic origin can be used in the context of the present invention as stable aromatic substances, respectively mixtures of aromatic substances, that is, aromas. Among these compounds are compounds listed below, as well as mixtures of them: ambrettolide, α-amylzimtaldehyde (α-amylzimtaldehyde), anethole, anisaldehyde, anise alcohol, anisole, anthranilic acid methyl ester, acetophenone, benzylacetone, benzaldehyde, ethyl benzoic acid ester, benzophenone, benzyl alcohol, benzyl acetate, benzyl benzoate, benzyl formate, benzyl valerianate, borneol, bornyl acetate, α-bromostyrene, n-decylaldehyde, n-dodecylaldehyde, eugenol, phengen methyl acetate, eucaliphenol acetate, farnisol, phenyl acetate, farne at, geranyl formate, heliotropin, heptin carboxylic acid methyl ester, heptaldehyde, hydroquinone dimethyl ether, hydroxycinnamic anhydride, hydroxycinnamic alcohol, indole, iron, isoevgenol, isoevgenolmethyl ether, isosafrol, jasmone, camphor, carvacrolum, carvacrol, carvacrol, carvacrol, carvacrol, carvacrol, carvacrol, carvacrol, carvacrol, carvacrol, carvacrol, carvacrol p-methoxyacetophenone, methyl-n-amylketone, methylanthranilic acid methyl ester, p-methylacetofonone, methylchavicol, p-methylquinoline, methyl-β-naphthyl ketone, methyl-n-nonyl acetaldehyde, methyl-n-nonyl ketone, muscon, ethyl β-naphthol β-naphthol methyl ester, nerol, nitrobenzene, n-nonylaldehyde, nonyl alcohol, n-octylaldehyde, p-hydroxy-acetophenone, pentadecanolide, β-phenylethyl alcohol, phenylacetaldehyde-dimethylacetal, phenylacetic acid, pulegloamic acid methyl ether, safole, methyl ether acids, salicylic acid hexyl ester, salicylic acid cyclohexyl ester, santalol, scatol, terpineol, thyme, thymol, γ-andelactone, vanillin, veratrumaldehyde, cinnamaldehyde, cinnamon alcohol, cinnamic acid, cinnamic acid ethyl ester, enzilovy ester of cinnamic acid.

Among the more volatile aromatic substances are more easily volatile aromatic substances of natural or synthetic origin, which can be used both on their own and in the form of mixtures. Examples of more easily volatile aromatic substances are alkyl isothiocyanates (alkyl mustard oils), butanedione, lemons, linalool, linalyl acetate, and propionate, menthol, menton, methyl n-heptenone, fellandren, phenylacetaldehyde, terpinyl acetate, citral, citronellall.

Particularly preferred deodorant sticks or antiperspirant sticks according to the invention are those in which at least one flavoring component is present in a total amount of from 0.00001% to 4% by weight, preferably 0.5% -2% by weight , respectively, in relation to the general compositions.

Penetration Values

In a further, particularly preferred embodiment, the stick compositions according to the invention are characterized by a penetration force in the range of 150-800 gram-force (g-force), preferably in the range of 350-700 gram-force (g-force), particularly preferably in the range of 450 -650 gram-force (g-force), with a penetration depth of 5.000 mm. The value of the penetration force is a measure of the hardness of the stick (or even a composition in the form of a solid cream) and the state at which the maximum force of a certain measuring probe, here a stainless steel cone with an angle of 45 ° (model TA 15), vertically (axially) pierces the mass of antiperspirant which they intend to measure, to a penetration depth of 5.000 mm (five point zero zero zero zero mm) with a penetration rate of 2 mm / s. The penetration force is measured by a TA-XT2i structure analyzer from Stable Micro Systems (Vienna Court, Lammas Road, Godalming, Su rrey GU7 1YL, England). The maximum force is given in gram-force (g-force). Here, the lowest values characterize a softer structure; harder structures have higher penetration strengths. Cream-type structures are often measured at a penetration depth of 10.000 mm (ten point zero, zero, zero mm) in order to obtain more accurate values. This penetration depth cannot usually be measured in masses of solid sticks, since in this case the mass of the stick is often destroyed. Double the depth of penetration means approximately tripling, up to quadrupling, the measured value of the maximum force. Measurements take place at ambient conditions of 30 ° C and 50% relative humidity; sample temperature 23 ° C. Measurements are preferably carried out 3 days and / or 4 weeks after the production of a stick according to the invention.

Antiperspirants with a cream consistency published in German patent applications DE 19962878 A1 and DE 19962881 A1 show penetration forces of 9-15 gram-force (g-force) under the measurement conditions mentioned above.

Electrical resistance

Modern water-based sticks are found almost exclusively in the form of water-in-oil emulsions or emulsions with an aqueous phase as a dispersed phase. In order to clearly and definitely protect the sticks corresponding to the invention from the level of technology, the measurement of electrical resistance serves as a quick and reliable test, since it usually consists in the study of emulsions. The oil-in-water system, due to the continuous aqueous phase, shows a higher electrical conductivity and corresponding lower electrical resistance than the water-in-oil system. In a further, particularly preferred embodiment, an electrical resistance of a maximum of 300 kOhm characterizes the stick structures of the invention. A maximum electrical resistance of 100 kOhm is preferred, a maximum of 80 kOhm is particularly preferred. Resistance is measured with a Voltcraft multimeter, model VC820, with automatic translation of the measurement interval (0-400 Ohm / 40 MΩ (± 1% + 2dgt)) and two micro tips, 1.0 mm measuring antennas made of stainless steel. The distance between the electrodes is fixed on a millimeter scale. The measurement is carried out at room temperature (22 ° C). To do this, the electrodes with micro tips are fixed in parallel, at a distance of 27.0 mm in millimeter scale and connected to a resistance measuring device. Electrical resistance measurements take place directly in water-containing antiperspirant sticks. Therefore, the generally curved surface of the antiperspirant sticks is removed with a knife until a flat cross section is obtained. Immediately after that, the measuring electrodes are thrust vertically, approximately 5 mm into the stick mass. The measured values of the electrical resistance are read after 30 s. The cleaning of the measuring electrodes is carried out using cellulose cloth soaked in alcohol. Under the mentioned measurement conditions, tap water exhibits an electrical resistance of 250 kOhm, and 20% by weight of an aqueous solution of aluminum hydrochloride 3 kOhm and fully distilled water - 1.7 MOhm.
