Antiperspirant composition containing at least one complex formed by the combination of at least one anionic species and at least one cationic species and method for treating human perspiration Invention of: Antiperspirant compositions containing at least one complex formed The present invention relates to a complex formed by the combination of at least one anionic species and at least one anionic species and at least one cationic species and method for treating human perspiration. a cationic species for the treatment of human perspiration comprising two suitably selected components which are intended to be mixed before application to the skin, at least one of whose species has no antiperspirant effect at the rate used in the composition. The invention also relates to a method of cosmetic treatment of human perspiration by involving the implementation of the complex as defined above. The armpits as well as certain other parts of the body are generally the place of several discomforts which can come directly or not from the phenomena of perspiration. These phenomena often lead to uncomfortable and uncomfortable sensations which are mainly due to the presence of perspiration resulting from perspiration which can, in some cases, make the skin moist and wet clothes, especially in the armpits or back, leaving visible traces. In addition, the presence of sweat can cause the release of body odors that are mostly unpleasant. Finally, during its evaporation, sweat can also leave salts and / or proteins on the surface of the skin which can cause whitish traces on clothing. Such discomforts are to be taken into account including in the case of moderate perspiration.

In the field of cosmetics, it is thus well known to use, in topical application, antiperspirant products containing substances which have the effect of limiting or even suppressing the flow of sweat in order to remedy the problems mentioned above. These products are generally available in the form of roll-on, sticks, aerosol or spray. The antiperspirant substances generally consist of aluminum salts, such as aluminum chloride and aluminum hydroxyhalides, or complexes of aluminum and zirconium. These substances reduce the flow of sweat by forming a plug at the level of the sweat duct. However, the use of these substances at high concentrations in order to obtain good efficiency causes difficulties in formulation. In addition, it has been found that the antiperspirant effectiveness of these substances is limited when used alone. This implies that these substances need to be repeatedly applied to the skin in order to achieve a satisfactory effective antiperspirant effect. Thus in the case of some users, repeated applications of these substances can lead to irritation of the skin. Finally, these antiperspirant substances can also leave traces during their application which has the effect of staining clothes. To overcome all the disadvantages mentioned above, it has been proposed to use antiperspirant compositions that are effective and properly tolerated by the skin. The limitation of the sweat flow can be achieved by partially obstructing the sweat ducts through the formation of a plug in the sweat duct but also by the formation on the skin surface of a film. Furthermore, international patent applications WO 2002/049590 and WO 2003/105795 describe antiperspirant compositions comprising polymers comprising one or more Bronsted acid groups capable of interacting with aluminum salts in contact with the skin so as to gel them to improve their effectiveness. However, these compositions contain aluminum salts which have the drawbacks described above. In addition, it has been observed that polymers comprising one or more Bronsted acid groups and aluminum salts must be formulated separately to minimize the risks of phase separation occurring by formation of an insoluble complex which may result in decrease in the effectiveness of aluminum salts. Thus, there is therefore a real need to use on the skin an agent intended for the treatment of human perspiration which does not have all the disadvantages described above, that is to say which gives an anti-aging effect. satisfactory perspiring, especially in terms of efficiency and resistance to sweat, tolerated by the skin and which can be easily formulated.

The Applicant has surprisingly discovered that by mixing a component having one or more cationic charges and a component having one or more anionic charges capable of reacting with one another via one or more ionic bonds, at least one Since the components have no antiperspirant effect, it is possible to formulate a complex having a suitable toxicological profile for the skin which gives a satisfactory antiperspirant effect, especially in terms of efficiency and sweat resistance. In other words, the Applicant has found that the combination of a component having one or more cationic charges and of a component having one or more anionic charges capable of reacting with one another by forming one or more ionic bonds, of which at least one of the components does not exhibit an antiperspirant effect, leads to the formation of complexes that are soluble in water or that are in the form of a colloidal dispersion having a particle size generally less than 1 m.

Thus the two compounds are selected so that they are able to react with each other through ionic bonds to form a complex having an antiperspirant activity. Cosmetic compositions comprising such a complex, once applied to the skin, make it possible to limit the flow of sweat. The formation of such a complex resulting from the combination of two compounds which have reacted with one another by forming one or more ionic bonds can be demonstrated by a microscopic study, in particular in white light, polarized light or phase contrast, or thanks to rheological or turbidimetric measurements. The present invention therefore particularly relates to an antiperspirant complex formed from a cosmetic composition A and a cosmetic composition B different from the cosmetic composition A, said cosmetic composition A comprising one or more compounds capable of reacting with a or several compounds of the cosmetic composition B forming one or more ionic bonds to impart an antiperspirant effect, at least one of said compositions A or B having no antiperspirant effect. By complex is meant the species formed by ionic association between the cosmetic composition A and the cosmetic composition B as defined below. The present invention also relates to a cosmetic composition containing a complex as defined above. Likewise, the present invention also relates to the use of a complex as defined above for the treatment of human perspiration, in particular for imparting an antiperspirant effect.

Another object of the present invention is also a method for the cosmetic treatment of human perspiration which consists in applying a composition containing a complex as defined above.

Other objects, features, aspects and advantages of the invention will emerge even more clearly on reading the description and examples which follow. By composition which does not have an antiperspirant effect, is meant, in the sense of the present invention, a composition which, applied on the surface of the skin, does not have the effect of reducing or significantly limiting the flow. sweat. In other words, such a composition, within the meaning of the present invention, has a weak influence on the flow of sweat.

By composition not having the effect of reducing or significantly limiting the flow of sweat, is meant in the sense of the present invention, a composition, which applied to the skin, decreases the sweat flow of a percentage noted R which is less than 10%. The percentage of reduction in the flow rate noted R is established according to the in vivo Bioskin gravimetric test. As an indication, the in vivo Bioskin gravimetric test gives the following scale: - percentage reduction R <10% no efficiency - percentage reduction 10 <R <15% low efficiency - percentage reduction 15 <R <25% average efficiency - percentage reduction 25 <R <35% good efficiency - percentage reduction 35 <R <50% high efficiency - percentage reduction R> 50% very important efficiency 25 Thus, according to the in vivo Bioskin gravimetric test, when the Percentage reduction of the sweat flow R is less than 10% so the composition has no antiperspirant efficacy. Thus, the cosmetic composition A and / or B according to the invention decreases the flow of sweat by a value of less than 10%. According to a first embodiment, the cosmetic composition A comprises one or more compounds capable of reacting with one or more compounds of the cosmetic composition B by means of a cation / anion reaction. According to this embodiment, the or the compounds of the cosmetic composition A and B are selected so that they react by forming one or more ionic bonds of cation / anion type, that is to say by involving a reaction between a compound having at least one cationic charge and a compound having at least one anionic charge. The compound (s) of the cosmetic composition A and B may be chosen from cationic surfactants, anionic surfactants, cationic polymers, anionic polymers, anionic or cationic particles or a mixture of these compounds.
