Title: Process for treating human transpiration using a cation and an anion in presence of a modulator

Description:
This invention relates to a cosmetic method for the treatment of human perspiration and optionally body odors resulting from the perspiration, which includes the use of at least one cation X n+  of valency n, of at least one anion Y m−  of valency m and of at least one modulating agent. 
     This invention in particular relates to a cosmetic method for the treatment of human perspiration and optionally body odors resulting from the perspiration, which includes 
     (i) either the mixing just before use of at least one composition A and of at least one composition B; said compositions A and B being packaged separately followed by the application of the resulting mixture on the surface of the skin; 
     (ii) or the application on the surface of the skin simultaneously or sequentially of at least one composition A and of at least one composition B packaged separately; 
     (iii) or the application on the surface of the skin of a composition comprising in the same support at least one composition A and of at least one composition B;
         said composition A comprising in a cosmetically acceptable medium at least one cation X n+  of valency n;   said composition B comprising in a cosmetically acceptable medium at least one anion Y m−  of valency m;   the mixture of said composition A with said composition B comprising in addition at least one modulating agent.       

     The underarms as well as certain other parts of the body are generally the place of several discomforts that can stem directly or not from perspiration problems. These phenomena often cause unpleasant and uncomfortable sensations which are primarily due to the presence of sweat resulting from perspiration that can, in certain cases, make the skin moist and wet clothing, in particular at the level of the underarms or the back, as such leaving visible traces. Moreover, the presence of sweat can generate the discharging of body odors that are most of the time unpleasant. Finally, during the evaporation thereof, sweat can also leave behind salts and/or proteins on the surface of the skin which can cause white traces on clothing. Such discomforts are to be taken into account including in the case of moderate perspiration. 
     In the cosmetics field, it is as such well known to use a topical application, antiperspirant products containing substances that have for effect to limit and even suppress the sweat flow so as to remedy the problems mentioned hereinabove. These products are in general available in the form of roll-on, sticks, aerosol or spray. 
     The antiperspirant substances are in general comprised of aluminum and/or zirconium hydrochlorides. These substances make it possible to reduce the sweat flow by forming a plug on the sweat channel. 
     However, the use of these substances at high concentrations in order to obtain good effectiveness causes difficulties in terms of the formulation. 
     In addition, it has been observed that the antiperspirant effectiveness of these substances is limited when they are used alone. This implies that these substances need to be applied several times on the skin in order to obtain a satisfactory effective antiperspirant effect. 
     Finally, these antiperspirant substances can also leave traces when they are applied which has the consequence of staining clothing. 
     In order to overcome all of these disadvantages mentioned hereinabove, it has been proposed to seek other effective active substances, that are tolerated by the skin and easy to formulate. 
     It has already been proposed in application US20070196303 to use cations of the calcium type and/or strontium type in the presence of a buffer comprised of an amino acid and of a betaine in order to reinforce the activity of the aluminum hydrochlorides. 
     It has also already been proposed in application WO0010512 to use cations of the calcium type in the presence of an acid solution with an amino acid and/or hydroxy acid base in order to reinforce the activity of aluminum and/or zirconium salts. The presence of aluminum and/or zirconium salts remains mandatory in these antiperspirant formulations. 
     As an alternative to the aluminum and/or zirconium hydrochlorides, it has already been proposed in patent WO2013/013902 an antiperspirant multi-component agent comprising a first component comprised of a cosmetic composition A and a second component comprised of a cosmetic composition B different from the cosmetic composition A, intended to be mixed before application on the skin or to be applied on the skin simultaneously, separately or delayed over time, said cosmetic composition A comprising a multivalent cation halide, and said composition B comprising a non-nitrogen-containing salt of an anion. The application mode is however rather restrictive for the consumer. 
     As such there is therefore a real need to implement on the skin an agent intended for the treatment of human perspiration that does not have all of the disadvantages described hereinabove, i.e. that provides a satisfactory antiperspirant effect, in particular in terms of effectiveness and resistance to sweat, and that is tolerated well by the skin. Furthermore, there is a need for such an agent intended for the treatment of human perspiration, that can be used alone or in association with an additional antiperspirant agent. Finally, such an agent must be able to be formulated in a way that is stable in storage. 
     The Applicant discovered surprisingly that this objective could be achieved by having recourse to a cosmetic method for the treatment of human perspiration and optionally body odors resulting from the perspiration, that includes the use of at least one cation X n+  of valency n, of at least one anion Y m−  of valency m and of at least one modulating agent. 
     This invention therefore relates to a cosmetic method for the treatment of human perspiration and optionally body odors resulting from the perspiration, that includes the use of at least one cation X n+  of valency n, of at least one anion Y m−  of valency m and of at least one modulating agent. 
     When the cation X n+  of valency n, the anion Y m−  of valency m and the modulating agent are formulated in an anhydrous medium, they can be present within the same composition (i.e. a single composition). 
     Alternatively, they can be formulated in two different compositions, one comprising the cation X n+  of valency n (composition A), and the other comprising the anion Y m−  of valency m (composition B). The modulating agent can however be present in the composition A and/or in the composition B. According to an alternative, the modulating agent is not introduced into the composition A or into the composition B, but it is generated during the mixture between the compositions A and B. 
     When the cation X n+  of valency n, the anion Y m−  of valency m and the modulating agent are formulated in an aqueous medium (i.e. comprising an aqueous phase, for example an aqueous solution or an oil-in-water or water-in-oil emulsion), the cation is necessarily formulated in a composition separate from the anion. 
     As such in this embodiment, preferably:
         the cation X n+  of valency n is present in a composition A;   the anion Y m−  of valency m is present in a composition B, the compositions A and B being different, and the composition A and/or B comprising at least an aqueous phase; and   the modulating agent is present in the composition A and/or in the composition B. According to an alternative, the modulating agent is not introduced into the composition A or into the composition B, but it is generated during the mixture between the compositions A and B.       

     Preferably, this invention relates to a cosmetic method for the treatment of human perspiration and optionally body odors resulting from the perspiration, that includes 
     (i) either the mixing just before use of at least one composition A and of at least one composition B, said compositions A and B being packaged separately, followed by the application of the resulting mixture on the surface of the skin; 
     (ii) or the application on the surface of the skin simultaneously or sequentially of at least one composition A and of at least one composition B packaged separately; 
     (iii) or the application on the surface of the skin of a composition comprising in the same support at least one composition A and of at least one composition B;
         said composition A comprising in a cosmetically acceptable medium at least one cation X n+  of valency n;   said composition B comprising in a cosmetically acceptable medium at least one anion Y m−  of valency m;   the mixture of said composition A with said composition B comprising in addition at least one modulating agent.       

     According to a first embodiment, the modulating agent can be present in the composition A and/or in the composition B. 
     According to a second embodiment, it can also not be present in the composition A or in the composition B, but be generated in situ following the mixture of said compositions A and B. 
     Such a method according to the invention is effective in the treatment of human perspiration. Furthermore, the compositions A and B are stable in storage. 
     This invention also relates to a cosmetic composition, in particular for the treatment of human perspiration and optionally body odors resulting from the perspiration, ready-to-use, that includes, in a cosmetically acceptable medium, at least one cation X n+  of valency n, of at least one anion Y m−  of valency m and of at least one modulating agent. This composition is called “ready-to-use composition” in this application. 
     The term “ready to use” means that the composition is applied on the surface of the skin in a very short period of time following the preparation thereof, for example from a few seconds to a few minutes following the preparation thereof. Typically, the time between the mixing of the cation(s) X n+  of valency n, anion(s) Y m−  of valency m and modulator(s) and the application on the skin is from 0 to 30 minutes, preferably from 0 to 10 minutes, preferably from 0 to 1 minute, and preferably from 0 to 30 seconds. 
     The term “antiperspirant agent” means any substance or any composition that has for effect to reduce sweat flow and/or reducing the damp sensation on the skin associated with human sweat and/or to mask human sweat. 
     The term “cosmetically acceptable medium” means a medium compatible with the skin and/or integuments or mucosa thereof, having a pleasant color, odor and texture and not giving rise to unacceptable discomfort (such as tightness), liable to dissuade the consumer from using the composition. 
     Said cosmetically acceptable medium is also a medium that does not leave any traces during the application thereof, and that does not as such stain clothing. 
     Said cosmetically acceptable medium can be anhydrous or include an aqueous phase. Preferably, it comprises an aqueous phase. Preferably in particular, the cosmetically acceptable medium of the ready-to-use composition comprises an aqueous phase.

     The term “sequential” means a successive administration.

     To take texturometric measurements, the formulas are poured when heated into jars 4 cm in diameter and 3 cm at the bottom. Cooling is performed at ambient temperature. The hardness of the formulas produced is measured after waiting 24 hours. The jars containing the samples are characterized by means of texturometric analysis using a texturometer such as that marketed by Rheo TA-XT2, according to the following protocol: a 5 mm diameter stainless steel ball type probe is brought into contact with the sample at a speed of 1 mm/s. The measurement system detects the interface with the sample with a detection threshold equal to 0.005 Newtons. The probe is inserted 0.3 mm into the sample, at a rate of 0.1 mm/s. The measurement apparatus records the progression of the compression force measured over time, during the penetration phase. The hardness of the sample corresponds to the mean of the maximum values of the force detected during penetration, for at least 3 measurements.

     According to a particular embodiment of the invention, the compositions A and/or B (or in the ready-to-use composition) in the form of an emulsion can be prepared according to the reverse phase manufacturing technique. This technique is, in its principle, well known and in particular described in the article “Phase Inversion Emusification”, by Th Förster et al, published in Cosmetics &amp; Toiletries, vol. 106, December 1991, pp 49-52. Its principle is as follows: 
     (i) In the presence of a suitable emulsifying system, with stirring, an oily phase on the one hand and an aqueous phase on the other hand are mixed, said mixture being carried out at a temperature greater than the phase inversion temperature (PIT) of the medium, in such a way as to obtain an emulsion of the water-in-oil type. 
     (ii) The temperature of the emulsion obtained as such is brought to a temperature less than said phase inversion temperature, this though which an ultrafine emulsion of the oil-in-water type is obtained. 
     (iii) Mineral nanopigments are then introduced during the implementation of the step (i) and/or at the end of the step (ii). 
     The suitable systems are emulsifiers of the non-ionic type and are chosen from polyoxyethylenated and/or polyoxypropylenated fatty alcohols (i.e. compounds obtained by a reaction between an aliphatic fatty alcohol, such as behenyl alcohol or cetyl alcohol, with ethylene oxide or propylene oxide or an ethylene oxide/propylene oxide mixture) and the esters of fatty acids and of polyols, optionally polyoxyethylenated and/or polyoxypropylenated (i.e. compounds obtained by a reaction of a fatty acid, such as stearic acid or oleic acid, with a polyol, such as for example an alkyleneglycol or glycerol or a polyglycerol, optionally in the presence of ethylene oxide or propylene oxide or an ethylene oxide/propylene oxide mixture), or mixtures thereof. 
     Moreover, and preferably, the emulsifying system retained will have a global HLB (HLB=Hydrophilic-Lipophilic Balance, in terms of Griffin; see J. Soc. Cosm. Chem. 1954 (vol 5), pp 249-256; balance between the hydrophilic nature and the lipophilic nature of the surfactant) ranging from 9.5 to about 11.5, advantageously close to 10, in such a way as to make it possible to obtain a phase inversion at a temperature less than 90° C. (TIP&lt;90° C.). 
     The content in emulsifying agent(s) is between 0.5 and 40% by weight and preferably between 2 and 10% by weight in relation to the total weight of the emulsion. 
     Oily Phase 
     The compositions A and/or B (or the ready-to-use composition or the single anhydrous composition) may contain at least one non-water-miscible organic liquid phase, known as a fatty phase. This generally includes one or a plurality of hydrophobic compounds rendering said phase non-miscible in water.

     In other words, the initial melting point of the pasty compound may be less than 23° C. The liquid fraction of the pasty compound measured at 23° C. may represent 9% to 97% by weight of the compound. This liquid fraction at 23° C. preferably represents between 15% and 85%, more preferably between 40% and 85% by weight. According to the invention, the melting point is equivalent to the temperature of the most endothermic peak observed in thermal analysis (DSC) as described in the standard ISO 11357-3; 1999. The melting point of a paste or a wax may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name “MDSC 2920” by 45 TA Instruments. 
     The measurement protocol is as follows: a 5 mg sample of pasty compound or wax (according to the case) placed in a crucible is subjected to a first temperature rise from −20° C. to 100° C., at a heating rate of 10° C./minute, and is then cooled from 100° C. to −20° C. at a cooling rate of 10° C./minute and finally subjected to a second temperature rise from −20° C. to 100° C. at a heating rate of 5° C./minute. During the second temperature rise, the variation in the difference in power absorbed by the empty crucible and by the crucible containing the pasty compound or wax sample as a function of temperature is measured. 
     The melting point of the compound is the value of the temperature equivalent to the top point of the peak of the curve representing the variation in the difference in power absorbed as a function of temperature. 
     The liquid fraction by weight of the pasty compound at 23° C. is equal to the ratio of the enthalpy of fusion consumed at 23° C. to the enthalpy of fusion of the pasty compound. 
     The enthalpy of fusion of the pasty compound is the enthalpy consumed by the compound to change from the solid state to the liquid state. The pasty compound is said to be in the solid state when the entire mass thereof is in solid crystalline form. The pasty compound is said to be in the liquid state when the entire mass thereof is in liquid form. 
     The enthalpy of fusion of the pasty compound is equal to the area under the curve of the thermogram obtained using differential scanning calorimeter (DSC), such as the calorimeter sold under the name MDSC 2920 by TA instrument, with a temperature rise of 5° C. or 10° C. per minute, according to the ISO 11357-3:1999 standard. The enthalpy of fusion of the pasty compound is the quantity of energy required to change the compound from the solid state to the liquid state. It is expressed in J/g. The enthalpy of fusion consumed at 23° C. is the quantity of energy required by the sample to change from the solid state to the state presented at 23° C. consisting of a liquid fraction and a solid fraction. 
     The liquid fraction of the pasty compound measured at 32° C. preferably represents 30% to 100% by weight of the compound, preferably 50% to 100%, more preferably 60% to 100% by weight of the compound. If the liquid fraction of the pasty compound measured at 32° C. is equal to 100%, the temperature of the end of the melting range of the pasty compound is less than or equal to 32° C. 
     The liquid fraction of the pasty compound at 32° C. is equal to the ratio of the enthalpy of fusion consumed at 32° C. to the enthalpy of fusion of the pasty compound. The enthalpy of fusion consumed at 32° C. is calculated as for the enthalpy of fusion consumed at 23° C. 
     The pasty compound is preferably chosen from synthetic compounds and plant-based compounds. A pasty compound may be obtained by means of synthesis from plant-based starting materials. The pasty compound is advantageously chosen from:

     Associative polyurethanes may be sequenced in triblock or multiblock form. The hydrophobic sequences may thus be at each end of the chain (for example: triblock copolymer having hydrophilic central sequence) or distributed both at the end and in the chain (multisequenced copolymer for example). These polymers may also be grafted or star polymers. Preferably, associative polyurethanes are triblock copolymers of which the hydrophilic sequence is a polyoxyethylenated chain comprising 50 to 1000 oxyethylenated groups. In general associative polyurethanes comprise a urethane bond between the hydrophilic sequences, hence the name.

The silanol groups may particularly be substituted with hydrophobic groups: a hydrophobic silica is thus obtained. The hydrophobic groups can be trimethylsiloxyl groups, particularly obtained by treating pyrogenic silica in the presence of hexamethyldisilazane. Silicas treated in this way are referred to as “Silica silylate” as per the CTFA (8th edition, 2000).

     Among the lipophilic gelling agents suitable for use, mention may also be made of dextrin and fatty acid esters, such as dextrin palmitates, particularly such as those sold under the names Rheopearl TL® or Rheopearl KL® by CHIBA FLOUR. 
     Use can also be made of polyorganosiloxane type silicone polyamides such as those described in the documents U.S. Pat. Nos. 5,874,069, 5,919,441, 6,051,216 and 5,981,680. 
     These silicone polyamides can belong to the following two families:

     The compositions A and/or B (or the ready-to-use composition or the single anhydrous composition) can furthermore contain one or several suspension agents and/or one or several gelling agents. Some of them can play both roles at the same time. 
     Among the agents that can be used as a suspension agent and/or as a lipophilic gelling agent, mention can be made of clays, in the form of powder or in the form of an oily gel; said clays optionally able to be modified in particular modified montmorillonites clays such as modified hydrophobic bentonites or hectorites such as the hectorites modified by a C10 to C22 ammonium chloride, such as hectorite modified with di-stearyl di-methyl ammonium chloride such as, for example, the product Disteardimonium Hectorite (CTFA name) (reaction product of hectorite and of disteardimonium chloride) sold under the name of Bentone 38 or Bentone Gel by Elementis Specialities. Mention can be made for example of the product Stearalkonium Bentonite (CTFA name) (reaction product of bentonite and stearalkonium chloride quaternary ammonium) such as the commercial product sold under the name TIXOGEL MP 250® by Sud Chemie Rheologicals, United Catalysts Inc. 
     Use can also be made of hydrotalcites, in particular modified hydrophobic hydrotalcites such as for example the products sold under the name of Gilugel by BK Giulini. 
     Mention may also be made of pyrogenic silica optionally with a hydrophobic surface treatment wherein the particle size is less than 1 μm. Indeed, it is possible to modify the surface of the silica chemically, by means of a chemical reaction giving rise to a reduction in the silanol groups present on the silica surface. The silanol groups may particularly be substituted with hydrophobic groups: a hydrophobic silica is thus obtained. The hydrophobic groups can be trimethylsiloxyl groups, particularly obtained by treating pyrogenic silica in the presence of hexamethyldisilazane. Silicas treated in this way are referred to as “Silica silylate” as per the CTFA (8th edition, 2000). They are for example marketed under the references Aerosil R812® by DEGUSSA, CAB-O-SIL TS-530® by CABOT, dimethylsilyloxyl or polydimethylsiloxane groups, particularly obtained by treating pyrogenic silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas treated in this way are referred to as “Silica dimethyl silylate” as per the CTFA (8th edition, 2000). They are for example sold under the references Aerosil R972®, and Aerosil R974® by DEGUSSA, CAB-O-SIL TS-610® and CAB-O-SIL TS-720® by CABOT. 
     The hydrophobic pyrogenic silica particularly has a particle size that may be nanometric to micrometric, for example ranging from approximately 5 to 200 nm. 
     According to a particular form of the invention, the suspension agents or gelling agents can be activated by oils such as propylene carbonate, triethylcitrate. 
     The quantities of these different constituents that can be present in the composition A and/or B (or in the ready-to-use composition or in the single anhydrous composition) are those conventionally used in compositions for the treatment of perspiration. 
     The suspension agents are present preferably in quantities ranging from 0.1% to 5% by weight and more preferably from 0.2 to 2% by weight with respect to the total weight of the composition. 
     The quantities of these different constituents that can be present in the cosmetic compositions A and/or B (or in the ready-to-use composition or in the single anhydrous composition) are those conventionally used in compositions for the treatment of perspiration. 
     Aerosols 
     The compositions A and/or B can also be pressurized and be packaged in an aerosol device, in particular comprising at least one propellant. 
     The propellant used is chosen preferably from dimethylether, volatile hydrocarbons such as propane, isopropane, n-butane, isobutane, n-pentane and isopentane and mixtures thereof, optionally with at least one chlorinated and/or fluorinated hydrocarbon; of the latter, mention may be made of the compounds sold by Dupont de Nemours under the trade names Freon® and Dymel®, and in particular monofluorotrichloromethane, difluorodichloromethane, tetrafluorodichloroethane and 1,1-difluoroethane particularly sold under the trade name DYMEL 152 A® by DUPONT. 
     Carbon dioxide, nitrous oxide, nitrogen or compressed air may also be used as a propellant. 
     Preferably, the propellant is chosen from the volatile hydrocarbons. 
     More preferably, the propellant is chosen from isopropane, n-butane, isobutane, pentane and isopentane and mixtures thereof. 
     The weight ratio between the liquid phase and the propellant gas varies in a ratio from 5/95 to 50/50, preferably from 10/90 to 40/60, and more preferably from 15/85 to 30/70. 
     According to the invention, the propellant concentration generally varies from 5 to 95% by pressurized mass and more preferentially from 50 to 85% by mass in relation to the total mass of the pressurized A and/or B composition. 
     The dispensing means, forming part of the aerosol device, generally consist of a dispensing valve controlled by a dispensing head, in turn comprising a nozzle via which the mixture of the composition A and of the composition B is sprayed. The receptacle containing each pressurized composition A and B may be opaque or transparent. It may be made of glass, polymeric or metal material, optionally coated with a layer of protective varnish. 
     Throughout the description, including the claims, the expression “comprising a” must be understood as being synonymous with “comprising at least one”, unless mentioned otherwise. 
     The expressions “between . . . and . . . ” and “ranging from . . . to . . . ” are to be understood to be inclusive of the limits, unless specified otherwise. 
     In the description and the examples, unless mentioned otherwise, the percentages are weight percentages. The percentages are therefore expressed by weight in relation to the total weight of the composition. The temperature is expressed in degrees Celsius unless mentioned otherwise, and the pressure is the atmospheric pressure, unless mentioned otherwise. 
     The invention is illustrated in more detail by the non-limiting examples presented hereinafter. 
     The examples that follow are used to illustrate this invention. The quantities are indicated as percentages by weight in relation to the total weight of the composition.

     The results show as such that the precipitation reaction between the compositions A1 and B1 on the one hand, and A2 and B1 on the other hand (therefore with a modulating agent according to the invention), is done in a much slower manner than between the comparative 1 compositions A and B1 (without modulating agent).

     For each composition A19, A20 and B5, B6, B7, B8 the protocol is as follows: 
     The phase P2 was introduced into the phase P1 with stirring. Once the mixture was homogeneous, the phase P3 was added with stirring. Then phase P4 was introduced with stirring. The formulas are at least 24 hours. 
     Example 25 
     Method of Application of the Compositions A and B According to the Invention 
     1) Aqueous Formulas: 
     Each aqueous composition A1 to A16, A19 and A20 of the examples hereinabove can be applied with one of the aqueous compositions B1 to B8. 
     For this, the method of application can comprise:
         the mixing just before use of at least one composition A chosen from A1 to A16, A19 and A20, with a compositions B chosen from B1 to B6, followed by the application of the resulting mixture on the surface of the skin;   application on the surface of the skin, at the same time (simultaneously) or one after the other (sequentially), of at least one composition A chosen from A1 to A16, A19 and A20, and of at least one composition B chosen from B1 to B8.       

     The composition A chosen from A1 to A16, A19 and A20, and the composition B chosen from B1 to B8, can be present in two separate supports, or in the same support. 
     2) Anhydrous Formula: 
     Typically, the anhydrous composition of the example 18 already contains the mixture of cation X n+ , of anion Y m−  and of modulating agent, and is directly applied on the skin. 
     EXAMPLE 26 
     Antiperspirant Clinical Effectiveness 
     Method: a gravimetric test was conducted with the compositions A11 and B3 of the example 11 in order to measure their antiperspirant effectiveness, compared to a control formula containing water. In sum, after a “wash-out” period of three weeks, thirty-four subjects were treated for 4 days twice a day on the underarm zone with 400 μl of each composition applied one after the other (composition A11 then composition B3) with a slight massage between the two. Twenty-four hours after the last application, the volunteers were subjected to a sauna at 38° C. and 35% RH (humidity) for forty minutes, during which their underarm sweat was collected using cotton pads that were tared beforehand which were weighed after collection 
     Results: 
     A reduction of 8.9% in the quantity of sweat was observed for the group treated according to the invention compared to the control group with a significance p&lt;0.017. 
     EXAMPLE 27 
     The following compositions are prepared by mixing ingredients of the composition A on one side (i.e. compositions A11 of example 11, or A21 or A22), and a mixture of the ingredients of the composition B (i.e. compositions B3 of example 11 above, or B9 to B11) on the other. 
     Then the composition B is introduced into the composition A with magnetic stirring. 
     The precipitation reaction time is measured as described in examples 1 to 11 above.
