Description

The present invention relates to skin care and / or makeup compositions, intended in particular to impart brightness or a light effect.

By "brightness" or "light effect" is meant according to the invention, the reflection characteristic of light, diffuse and continuous reflection on the skin. Indeed, the skin naturally reflects some of the incident light. The light effect according to the invention makes it possible to increase this reflection, which makes the makeup brighter and more radiant.

Consumers are looking for new cosmetic products with a fluid, fresh, and fine texture associated with a result of care and / or fine makeup, non-powdery, non-marking but nevertheless covering and luminous to perform in the attenuation of defects , in particular the appearance of surface (visible and / or tactile irregularities), and bring brightness to the complexion, external sign of good looks, health and youth.

These fluid textures, particularly sought for oily skin and in hot countries, are nevertheless more difficult to stabilize, especially when they contain a high rate of water and alcohols (for the fresh effect), associated with the presence fillers and pigments (for coverage effect and color effect). This is all the more true for W / O emulsions, which are classic in the field of foundations.

Moreover, these fresh formulas are advantageously lightly loaded in the sense of containing few charges; however it is important that these formulas are covering to hide the defects (dyschromias, spots, irregularities ... of the skin). This is particularly true in Asia, Japan where, while being fresh, light and fine, the textures must provide coverage. It is therefore important to have in these formulas materials that know, without destabilizing and without thickening these textures, bring coverage but also brightness

It is known from the prior art the use of fillers to provide coverage and pigments (including TiO2) which, for the latter, bring color in addition to the coverage. They make it possible to modulate the visual coverage of the skin by the application of a composition (eg foundation) containing said fillers / pigments and thus give consumers the possibility of: - unifying the color of the complexion, even to enhance it when the woman (the man) judges that his natural complexion is not in phase with the image that she (he) wants to give of her (of him), the climate, the season .. .; and / or - to correct the faults that have hindered them forever or that, as they come of age, occur and that they (he) would like to mitigate or hide. Unfortunately these raw materials can mark the face by highlighting the relief and the microrelief of the face. This is all the more unfortunate as age is a factor of accentuation of this microrelief and it is not welcome for these consumers to accentuate the latter by the same foundation that they (they) use to cover and color their face. Moreover, these same raw materials, also have the advantage of bringing dullness to the face but by this very fact can confer a dullness to the complexion.

There remains therefore the need to find new skincare and / or makeup products with fluid texture, fresh and fine, associated with a result of care and / or fine makeup, non-powdery, non-marking but nevertheless covering and bright. The inventors have demonstrated that the use of a dispersion of bismuth oxychloride in an ester or an oil whose solubility parameter at 25 ° C, 5a, is greater than 6 (J / cros) '12, in In particular, a dispersion of bismuth oxychloride in ethyl (2) hexyl hydroxystearate (INCI name ethylhexyl hydroxystearate), hitherto known in anhydrous varnish, gloss, eyeshadow compositions, for its brilliant effect, allowed formulated in an emulsion for application to the skin and containing a high level of water and alcohols, to give the skin luminosity and a fresh effect; the complexion thus finds the freshness and brightness of youth. Compared with the use of nacres or titanium dioxide-type pigments conventionally used for the search for a covering and luminous effect, the effect obtained with the dispersion of bismuth oxychloride used according to the invention is advantageously homogeneous, and without scintillating point.

The use of bismuth oxychloride (Cl 77163) in the form of powder or agglomerates was known in the foundations as a filler intended to provide a certain sensorality (soft touch). This compound could also provide a satin effect, punctual and discontinuous, which in products such as fluids, compacts or even powders can be perceived as a pearly shine and not the desired fade. WO2004 / 041234 also describes lightening and whitening anhydrous compositions comprising Phyllanthus emblica extract (PE) and, as an additive, bismuth oxychloride in the form of a powder or a dispersion to give the composition a dry, soft feel on the skin. the skin.

The dispersion form (Biron Liquid Silver) is described in this application and marketed by the supplier Merck, as a highly shiny, highly glossy raw material, which are not desirable properties for application to the skin of the face, and especially for the complexion. When viewed pure, it is a very silvery and extremely brilliant liquid, indicated and recommended by the supplier for use in compositions such as gloss, varnish and eye shadow, but a priori unsuitable for the expectations a result of complexion makeup.

Thus, to the knowledge of the Applicant, it has never been suggested, and it even appears to be contraindicated, to specifically use a dispersion of bismuth oxychloride in an oily dispersant as defined hereinafter, in cosmetic formulations. in the form of emulsions for topical application to the skin, to impart a light effect, and coverage to the complexion. It is therefore very surprising that we have demonstrated that the use of this dispersion of bismuth oxychloride in ethyl (2) hexyl hydroxystearate could lead to care products and / or makeup including complexion, especially of emulsion type, the ability to provide after application / makeup: a) coverage, b) and especially brightness. The invention thus relates to a cosmetic composition in the form of an emulsion for topical application to keratinous substances, in particular the skin, comprising, in a physiologically acceptable medium: (i) an aqueous phase forming 30 to 70% by weight relative to the total weight of said composition, (ii) at least 5% by weight relative to the total weight of the composition of at least one C2-C8 monoalcohol, and (iii) at least one oxychloride dispersion bismuth (Cl 77163) in an oily dispersant (an oil) chosen from a) monoesters of formula R, wherein R, represents a linear or branched hydrocarbon-based chain containing from 4 to 40 carbon atoms, preferably from 4 to 30 carbon atoms, and preferably 7 to 20 carbon atoms, and R2 represents a branched hydrocarbon chain containing from 3 to 40 carbon atoms, preferably from 10 to 30 carbon atoms, and preferably from 16 to 26 atoms s carbon; b) polar oils whose solubility parameter at 25 ° C, 5a, is greater than 6 (J / cm 3) 12, and mixtures thereof. 10

The invention also relates to a method for preparing an emulsion according to the invention, characterized in that a) is introduced into the fatty phase, a dispersion of bismuth oxychloride comprising 68% to 72% by weight of bismuth oxychloride in 28% to 32% by weight of ethyl (2) hexyl hydroxystearate, relative to the total weight of the dispersion, b) the aqueous phase is prepared separately, and c) the emulsion is strong agitation and at room temperature, in particular using a Rayneri deflocculator and c) the C 2 -C 8 monoalcohol is incorporated with moderate stirring.

The invention also relates to a cosmetic process for the care and / or makeup of keratinous materials, comprising the application, on said keratin materials, in particular on the skin, of a composition according to the invention, for example in the form of a layer of composition or of several composition keys applied to the skin of the face, used alone or in combination with another composition (double-action application), said composition according to the invention being applied before and / or after the application of a care composition or a makeup composition such as a foundation. In particular, the application of said composition on the skin, in particular the face, gives it a luminous effect, good coverage and a fresh effect.

The invention also relates to the use of a dispersion of bismuth oxychloride in an oily dispersant as defined according to the invention, in a cosmetic composition according to the invention, as an agent for giving luminosity to complexion.
