Description

Colored skincare and / or makeup composition FIELD OF INVENTION The present invention relates to the cosmetic field and in particular to colored cosmetic compositions for the care and / or makeup of keratinous materials, in particular of the skin, eyelids, eyebrows or lips. STATE OF THE ART Anhydrous coloured skincare and / or lip makeup products are sought after by consumers for their coverage, hold, and colour properties for a skin and / or lip makeup effect. Coverage is generally achieved with white pigments and / or fillers, notably titanium dioxide, which is used for its high opacity and covering power. Color is provided by colorants, both organic and inorganic, some of which are known to be light-sensitive. This sensitivity can lead to color or hue instability on the surface when the composition is exposed to light. The color or hue on the surface of the composition exposed to light loses intensity and / or saturation; the surface of the composition is also said to fade in light. Therefore, efforts are made to preserve and protect light-sensitive colorants to prevent these variations in hue or color. Unexpectedly, the Applicant demonstrated that the use of zinc oxide particles, particularly in an anhydrous composition containing light-sensitive colorants, protected these colorants and thus promoted the stability of the composition's color and shade. Zinc oxide particles are therefore particularly advantageous, as a replacement for titanium dioxide particles, in the formulation of skincare and / or makeup compositions to provide coverage and, moreover, to protect light-sensitive colorants. The use of these zinc oxide particles thus makes it possible to obtain stable shades, even with light-sensitive pigments, which titanium dioxide could not achieve. DESCRIPTION OF THE INVENTION A first aspect of the invention is therefore a cosmetic composition, preferably anhydrous, for the care and / or makeup of keratinous materials, in particular of the skin, eyelids, eyebrows or lips, comprising, in a physiologically acceptable medium: (i) Zinc oxide particles, and (ii) One or more light-sensitive colouring materials, selected from the group consisting of organic dyes and pigments, composite pigments comprising at least one of said organic dyes or pigments, pearlescent pigments comprising at least one of said organic dyes or pigments, and mixtures thereof. According to a particular and preferred method, the composition of the invention is an anhydrous composition. The present invention also relates to a cosmetic process for the care and / or makeup of keratinous materials, in particular the skin, eyelids, eyebrows or lips, preferably the lips, comprising the application on said keratinous materials of a composition according to the invention. DETAILED DESCRIPTION OF THE INVENTION The present invention therefore relates to a cosmetic composition, preferably anhydrous, for the care and / or makeup of keratinous materials, in particular of the skin, eyelids, eyebrows or lips, comprising, in a physiologically acceptable medium: (i) Zinc oxide particles, and (ii) One or more light-sensitive colouring materials, selected from the group consisting of organic dyes and pigments, composite pigments comprising at least one of said organic dyes or pigments, pearlescent pigments comprising at least one of said organic dyes or pigments, and mixtures thereof. By "anhydrous composition," it is understood, in particular, that water is preferably not deliberately added to the composition of the invention but may be present in trace amounts in the various compounds used in the composition. In particular, the composition according to the invention comprises less than 4% by weight of water, preferably less than 3%, preferably less than 2%, more preferably less than 1%, and even more preferably less than 0.5% by weight of water, relative to the total weight of said composition, or is even completely free of water. According to a particular embodiment, the composition is free of water. According to one embodiment, the composition is fluid or liquid, that is to say, it flows under its own weight at ambient temperature and atmospheric pressure. According to another embodiment, the composition is in the form of a powder, in particular a loose powder. According to another embodiment, the composition is a solid composition. Preferably, the solid composition comprises one or more waxes. By "solid composition", as opposed to liquid or fluid composition or free powder, is meant according to the invention a composition which does not flow under its own weight at ambient temperature and atmospheric pressure. The composition may be in the form of a compact powder, a stick, or a composition packaged in a cup. The term "compacted powder" refers to a solid composition based on powders, distinct from a loose powder. Compacted powder is generally prepared by mixing all the components of the particulate phase and then adding a liquid phase to this mixture while stirring. The mixture is then poured into a cup, a container, or a mold and compacted. Compaction is typically carried out at a pressure of 5 to 25 MPa and results in a reduction in the volume of the compacted composition. PULVERULENT PHASE The powdered phase of the composition includes fillers and pigments. The composition of the invention includes, in particular, zinc oxide particles. Zinc oxide particles Zinc oxide particles are in the form of a white powder and are insoluble in water. Zinc oxide particles can occur in a heterogeneous form, usually hexagonal and cubic in shape. The zinc oxide particles used according to the invention are pigmentary zinc oxide particles, as opposed to zinc oxide nanoparticles used as a mineral sunscreen. The average size of the zinc oxide particles used according to the invention will generally range from 0.1 to 50 pm (micrometers), in particular from 0.1 to 10 pm, or even from 0.1 to 1 m. Particle size can be measured using a laser diffraction distribution method with a Malvern Mastersizer-type device, specifically by measuring the D value.

[0050] , which represents the maximum size that 50% of the particle volume represents. Examples include the commercial references RONACARE ZINC OXIDE from Merck, or the reference A120-ZnO-11 S3 from Kobo, or the reference ZINC OXIDE COSMETICS from Keyser&Mackay / Grillo. According to a particular and preferred mode, zinc oxide particles contain more than 80% by weight of ZnO, in particular more than 95%, 96%, 97%, 98%, or 99% by weight of ZnO, or even 100% of ZnO. The zinc oxide particles used according to the invention may or may not be treated with a lipophilic treatment agent for better dispersion in the oil phase. According to a particular embodiment of the invention, the zinc oxide particles are not treated and they have the INCI name: Zinc oxide. In another particular method, the zinc oxide particles are treated with a lipophilic treatment agent. Zinc oxide particles can also be mixed with a wetting agent to facilitate their dispersion in the composition and thus improve the homogeneity of the composition. According to a particular method, the content of zinc oxide particles in the composition of the invention will generally range from 0.1% to 50% by weight of zinc oxide, in particular from 1% to 30% by weight of zinc oxide, preferably from 2% to 20% by weight of zinc oxide relative to the total weight of the composition. For a compact powder composition (e.g., eyeshadow, face powder), the total zinc oxide particle content will generally range from 1% to 50%, or better yet, from 5% to 40% by weight (of zinc oxide) relative to the total weight of the composition. For an anhydrous solid composition for the skin and distinct from a powder (e.g., complexion corrector), the total content of zinc oxide particles will generally range from 0.5% to 30%, better from 1% to 20% by weight (of zinc oxide) relative to the total weight of the composition. For an anhydrous solid lip composition (e.g., lip balm), the total zinc oxide particle content will generally range from 0.1% to 30%, preferably from 0.5% to 20% (zinc oxide) by weight relative to the total weight of the composition. According to a particular and preferred embodiment of the invention, the composition comprises less than 3% by weight of titanium dioxide relative to the total weight of the composition, in particular less than 1%, or even is free of titanium dioxide. According to an even more preferred method, the composition of the invention is free of titanium dioxide. The composition also includes one or more light-sensitive coloring materials. Light-sensitive coloring materials For the purposes of this invention, "coloring material" means a compound capable of producing a colored optical effect when formulated in sufficient quantity in a suitable cosmetic medium. Coloring materials are conventionally chosen from pigments (insoluble in oils and in the aqueous phase) and dyes (soluble in oils or in the aqueous phase). Colouring materials can be made of mineral, synthetic or natural origin. Depending on the specific method, the coloring materials are of mineral or synthetic origin. The said coloring materials may or may not be treated with a lipophilic treatment agent. A light-sensitive coloring material usable in the compositions of the invention may be chosen from the group consisting of organic dyes and pigments and / or their salts, composite pigments comprising at least one of said organic colorants or pigments, pearlescent pigments comprising at least one of said organic colorants or pigments, and mixtures thereof. Light-sensitive colorants are defined as colorants whose color (e.g., a single colorant) or tint (e.g., a mixture of colorants) in formulation is not stable after exposure to light. Color or tint stability can be observed with the naked eye by a color expert or measured using a spectrocolorimeter by calculating the color difference (AE₀) between two samples (irradiated vs. control). A color or tint that is not light-stable is one that loses intensity and / or saturation. The surface of the composition is also said to decolorize in light. To select light-sensitive colorants suitable for use in the compositions of the invention, the following test (also known as the 'Sun Test') can be used, which aims to identify colorants whose color or tint in formulation is impacted by exposure to light, for example, irradiation for 16 hours: The colouring material is generally pre-dispersed (for pigments) or solubilised (for dyes) in an oil and then the mixture (also called 'pigment paste') is dispersed homogeneously in an oily or greasy base including for example hydrocarbon oils and waxes as described below by way of illustration; The composition obtained in the previous step is then conditioned in two cups, one serving as a control and the other being subjected to irradiation, for example for 16 hours; the irradiation is carried out using a Sun Test XLS type device, at a power of 500W / m2, for 16h, with a Store light reduced IR filter; The hues of the irradiated composition versus the control (non-irradiated) composition are evaluated by an expert colorist who observes and describes the color or hue of each composition or by measuring a color difference AEoo according to the protocol described below; A shade that varies (e.g., loses intensity and / or saturation, fades) in the irradiated condition compared to the control condition (for example, an AEoo measurement greater than 1, especially greater than 3, more particularly greater than 8, or even greater than 10 between the irradiated composition versus the non-irradiated control) indicates that the colouring material in formulation is a light-sensitive colouring material, capable of being used in the present invention in association with zinc oxide particles which will prevent this colouring. The AEoo parameter is evaluated according to the following protocol. The colorimetric parameters of the compositions are measured using a spectrocolorimeter such as a d / 8° spectrocolorimeter (COLOR17800 X Rite). The device is used in specular mode, with a 17mm aperture window, UV is excluded from the light source. Spectral measurements are performed on each sample before and after irradiation. The colorimetric values ​​are calculated in the CIELÀB76 space, in which L* represents the color intensity, a* indicates the green / red color axis and b* the blue / yellow color axis, illuminating D65, observer 10°. Color deviations are calculated to evaluate the colorimetric evolution of the samples between the hue of the irradiated composition versus the control composition: lightness deviation DL*ab, chroma deviation DC*ab, hue deviation DH*ab (ISO / CIE 11664-4:2019) and overall color deviation AEoo determined as defined by the CIE (ISO / CIE 11664-6:2014). As an example for implementing this test, the following oily and greasy base can be used: [Table 1] This mixture is used as a dispersion base (once melted) for bichromatic pigment preparations with equivalent TiO2 (opacifier) ​​and colorant contents. The mixture of "Base + TiO2 pigment paste + colorant pigment paste" is adjusted to achieve a level of color saturation similar to that found in products currently on the market; the texture The pigment concentration is adjusted by adding a polyglycerol ester. Pigment pastes are dispersions of coloring materials in a polyglycerol ester of a known concentration, prepared freshly. For example, 60% of this base is mixed with 5% of a TiO2 pigment paste (3% TiO2 pre-dispersed in the polyglycerol ester), 10% of the Red 28 Lake pigment paste to be tested (3% Red 28 Lake pre-dispersed in the polyglycerol ester), and 25% polyglycerol ester (to bring the composition to 100%). This mixture is heated to 95°C and homogenized using a rotor-stator to ensure good color uniformity. The product is poured at a temperature of approximately 90°C into a mold. The mold is left at room temperature for a few minutes, then placed in the freezer for 5 minutes. At the end, the product is either unmolded or left in its mold and placed to rest for a minimum of 24 hours before undergoing the Sun Test. The protocol steps are followed, and the SunTest is used to assess whether the irradiated tint differs from the control tint. Compositions showing a tint variation indicate that the tested colorant is light-sensitive. The Applicant tested, in particular, the organic dyes and pigments Red 28 Lake, Red 6 Salt, Blue 1 Lake and a mica-based mother-of-pearl coated with Red 6 and showed a variation in shade according to this protocol, with the greatest variation for Red 28 Lake, the most sensitive to light.

Light-sensitive composite pigments usable according to the invention therefore comprise a substrate and at least one of the aforementioned light-sensitive organic colorants or pigment(s).

COSMETIC PROCESS The invention also relates to a cosmetic process for the care and / or makeup of keratinous materials comprising the application, on said keratinous materials, in particular the skin, eyelids, eyebrows, or lips, preferably the lips, of a composition according to the invention. The compositions of the invention are as defined above. In a particular method, the composition applied to the skin is in the form of a compact powder.

Tl an eyeshadow or eyeshadow, or a complexion corrector or concealer, preferably a lip gloss or lip balm. The invention will now be illustrated in the following non-limiting examples. Unless otherwise stated, percentages are expressed as a percentage by weight of ingredient relative to the total weight of the composition. EXAMPLES Example 1: Effect of zinc oxide particles on color protection Several tests were done beforehand to determine the coverage power of zinc oxide particles, compared to titanium dioxide, in order to be able to replace titanium dioxide in formulas, without impacting the desired coverage effect. These results showed that, for equivalent coverage, in an anhydrous solid composition according to the invention, a quantity of zinc oxide particles approximately 3 to 4 times greater than the quantity of titanium dioxide was required for an equivalent coverage result. We tested various organic colorants and pigments (e.g., lacquers) and a mother-of-pearl in a lipstick base as described below: [Table 2] This mixture is used as a dispersion base (once melted) for bichromatic pigment preparations with equivalent TiO2 (opacifier) ​​and colorant contents. The mixture is: "Base + TiO2 Pigment Paste + Pigment Paste of The colorant content is adjusted to achieve a level of color saturation similar to that found in products currently on the market; the texture is adjusted by adding a polyglycerol ester. Pigment pastes are dispersions of colorants in a polyglycerol ester of a known concentration, prepared extemporaneously. To facilitate reading the first line of the table, 60% of this base was mixed with 5% of a TiO2 pigment paste (3% TiO2 pre-dispersed in polyglycerol ester), 10% of the Red 28 Lake pigment paste to be tested (3% Red 28 Lake pre-dispersed in polyglycerol ester), and 25% polyglycerol ester (to bring the composition to 100%). This mixture was heated to 95°C and homogenized using a rotor-stator to ensure good color uniformity. The product was poured at a temperature of approximately 90°C into a mold. The mold was left at room temperature for a few minutes, then placed in the freezer for 5 minutes. Afterward, the product was either unmolded or left in its mold and left to rest for a minimum of 24 hours before undergoing the Sun Test. Color evaluation by Sun Test: The color stability properties of the compositions under light were evaluated according to a 'Sun Test' protocol, in which the compositions are subjected to irradiation for 16 hours. Each composition is poured into two lipstick pots: one control and one that will be irradiated for 16 hours. Irradiation is carried out using a Sun Test XLS type device, at a power of 500W / m2, for 16h, with a Store light reduced IR filter. The hues of each composition tested, compared to the control composition (non-irradiated), are evaluated by a colorist who observes and describes the color variation of each composition. The results are presented in the following table: [Table 3] ZnO *4: The amount of ZnO is multiplied by 4 compared to the amount of TiOZ to obtain the same coverage and achieve a 'same shade' in the examples. These results show that zinc oxide (ZnO) particles have a protective effect against the fading of light-sensitive colorants. Example 2: Formulations The following examples are illustrative and non-limiting examples of the invention, prepared according to methods well known to the cosmetic formulator. 2.1 Liquid anhydrous lip gloss [Table 4] 2.2 Compact Powder [Table 5] The compact powder exhibits good color stability in light. Applied to the skin, it provides good coverage and color payoff. 2.3 Anhydrous lip balm [Table 6] The lipstick exhibits good color stability in light. When applied to the lips, the lipstick provides good coverage and color payoff. 2.4 Anhydrous eyeshadow [Table 7] The eyeshadow, packaged in a small dish, has good colorfastness in the light. Applied to the eyelids, the eyeshadow provides coverage and a pearly effect.
