Definitions
- Anhydrous antiperspirant composition in aerosol form comprising an antiperspirant active agent and a vinylpyrrolidone-derived polymer
- the present invention relates to an anhydrous antiperspirant composition in aerosol form comprising, in a physiologically acceptable, in particular cosmetically acceptable, medium, i) an oily phase comprising:
- At least one antiperspirant active agent chosen from aluminium and/or zirconium salts or complexes
- Another subject of the invention is a cosmetic process for treating human perspiration, and optionally the body odours associated with human perspiration, especially underarm odours, comprising the application of said composition to a surface of the skin.
- the present invention also relates to the use of said cosmetic composition and also to an aerosol device using it.
- the armpits and also certain other parts of the body are generally the site of much discomfort that may arise directly or indirectly from perspiration.
- This perspiration often leads to unpleasant and disagreeable sensations that are mainly due to the presence of sweat resulting from perspiration, which may, in certain cases, make the skin clammy and clothing wet, especially in the region of the armpits or of the back, thus leaving visible marks.
- sweat may also leave salts and/or proteins on the surface of the skin, which thus results in whitish marks on clothing. Such discomfort is noticed, including in the case of moderate perspiration.
- antiperspirant products containing substances that have the effect of limiting or even preventing the flow of sweat in order to overcome the problems mentioned above.
- These products are generally available in the form of roll-ons, sticks, aerosols or sprays.
- Antiperspirant substances are generally composed of aluminium and/or zirconium salts or complexes, such as aluminium chloride and aluminium hydroxyhalides. These substances make it possible to reduce the flow of sweat.
- cosmetic compositions based on these antiperspirant substances generally have a tendency to become transferred onto clothing, leaving unsightly, visible marks.
- antiperspirant compositions containing oils with a refractive index close to those of aluminium salts have been developed.
- the role of such oils is to reduce the whitish appearance of antiperspirant compositions when they are deposited on the skin and, consequently, to make the marks on clothing less white.
- the oils used are generally fatty acid esters such as isopropyl myristate or polydimethylsiloxanes.
- Such compositions have especially been described in patents or patent applications EP 1362885, JP 030951 1 1 and FR 2242969.
- such antiperspirant compositions have the drawback of giving the skin, especially on the armpits, an oily sensation that is unpleasant for the user, and do not make it possible to limit the transfer of antiperspirant products from the skin onto clothing.
- an anhydrous composition in aerosol form containing an oily phase comprising at least one volatile oil, at least one antiperspirant active agent preferably chosen from aluminium and/or zirconium salts or complexes, at least one vinylpyrrolidone-derived polymer and at least one propellant, it was possible to minimize the problems of transfer of antiperspirant compositions onto fabrics while maintaining antiperspirant efficacy.
- the antiperspirant cosmetic composition in aerosol form in accordance with the invention leads to formulations which transfer less onto textiles, thus giving rise to fewer unsightly visible marks on clothing, especially on dark-coloured clothing, compared to a standard antiperspirant composition or an antiperspirant composition containing oils.
- the antiperspirant cosmetic composition makes it possible to significantly reduce the whitish marks on clothing, in particular on dark- coloured clothing.
- the cosmetic composition in aerosol form according to the invention maintains good antiperspirant efficacy.
- vinylpyrrolidone-derived polymers as described below in an antiperspirant composition based on aluminium salts makes it possible to reduce the transfer of unsightly visible marks onto clothing without harming the efficacy of the aluminium salts.
- the vinylpyrrolidone-derived polymers used prove to be compatible with the aluminium salts since they do not form a macroscopically visible precipitate in the composition.
- One subject of the present invention is thus especially an anhydrous composition in aerosol form, containing: i) an oily phase comprising:
- At least one antiperspirant active agent chosen from aluminium and/or zirconium salts or complexes
- the cosmetic composition according to the invention has both good transfer-resistance and antiperspirant properties.
- the present invention also relates to a cosmetic process for treating human perspiration, and optionally body odours associated with human perspiration, which consists in applying to the surface of a human keratin material an effective amount of the cosmetic composition as described previously.
- the process according to the invention is particularly advantageous for treating armpit perspiration, since the composition used does not give an unpleasant oily sensation and transfers less onto clothing, while at the same time efficiently treating perspiration.
- the invention also relates to the use of said composition cosmetically treating human perspiration.
- Other subjects, characteristics, aspects and advantages of the invention will emerge even more clearly on reading the description and the examples that follow.
- physiologically acceptable medium is intended to denote a medium that is suitable for the topical administration of a composition.
- a physiologically acceptable medium is preferentially a cosmetically or dermatologically acceptable medium, i.e. a medium that has no unpleasant colour or appearance, and that is entirely compatible with the topical administration route.

- an aerosol device composed of a container comprising an aerosol composition as defined above and of a means for dispensing said composition.
- the dispensing means which forms a part of the aerosol device, generally consists of a dispensing valve controlled by a dispensing head, which itself comprises a nozzle via which the aerosol composition is vaporized.
- the container containing the pressurized composition may be opaque or transparent. It may be made of glass, polymer or metal, optionally coated with a protective varnish coat.
- the transfer may also be evaluated by observing the residual deposit on the plate of synthetic leather: the fabric is then scanned with a scanner sold under the trade name Scanner Epson V500 (16-bit grey setting, resolution 300 dpi).
- the grey level of the scans is then analyzed using ImageJ software which has a grey level ranging from 0 to 255. The higher the grey level value, the stronger the marks. It is thus sought to obtain the lowest possible grey level values.
- the wear property is considered to be very good when the deposit is unchanged after the fabric has been passed over.
- composition of the artificial sweat is considered to be poor when the deposit is no longer (or only slightly) visible after the fabric has been passed over.
- the tackiness may, where appropriate, also be measured to evaluate the tackiness of the compositions according to the invention. This measurement is then carried out according to the protocol described below:
- the texture analyzer is placed in a glovebox so as to work in a temperature- and humidity-controlled atmosphere.
- the probe applies a force of 400 g on the sample.
- the apparatus then calculates the force required for the probe to separate from the sample. In the case of the experiment, only the maximum force which represents the strength of the tackiness of the formula at this given moment is retained. This type of measurement is carried out every 30 seconds for 320 seconds.
- the evaluation of the tackiness is the following:
- the tackiness is considered to be low when the detachment force is less than 60 g.
- the tackiness is considered to be medium when the detachment force is between 60 g and 120 g.
- the tackiness is considered to be high when the detachment force is greater than 120 g.
