Description

Title of the invention: Composition with a polyphenol, an aqueous dispersion of wax, a non-ionic surfactant of HLB greater than or equal to 8 and uncoated iron oxide

[0001] The present invention relates to the field of care and / or makeup of keratinous materials, and aims to offer compositions more particularly dedicated to makeup of the skin, in particular of the face, the eye contour, eyelashes or eyebrows.

[0002] Skincare and / or makeup compositions such as foundations are commonly used to provide aesthetic color to the skin, but also to enhance uneven skin tone by concealing blemishes and discoloration, reducing the visibility of surface imperfections such as pores and wrinkles, and masking blemishes, acne marks, and scars. In this respect, coverage and a matte or "soft focus" finish are the main properties sought.

[0003] Compositions designed for applying makeup to keratin fibers, such as eyelashes, like mascaras, aim to increase the thickness and visual perception of eyelashes, and ultimately enhance the appearance of the eyes. These mascaras are classified as aqueous or cream mascaras when formulated with an aqueous base, and as anhydrous mascaras when formulated as a dispersion in an organic solvent. A wide variety of cosmetic effects can be achieved by applying mascara to keratin fibers, particularly eyelashes, such as a volumizing, lengthening, thickening, and, more specifically, a fuller look.

[0004] Makeup compositions of keratinous materials generally include pigments. They most often contain thickening polymers to ensure a homogeneous and stable composition over time. Indeed, the presence of a thickening polymer allows for control of the homogeneity of the composition as well as the homogeneity of the color in the application. However, the presence of such a thickening polymer in the composition significantly increases viscosity and adversely alters the sensory experience during application. In particular, the deposits are thicker and therefore more concentrated on the keratinous material. The absence of a thickening polymer leads to sedimentation of the pigments, which requires the user to shake the composition before each application to re-homogenize it.

[0005] There therefore remains a need to find new skincare and / or makeup compositions for keratinous materials based on pigments, without thickening polymers, These compositions must be homogeneous and stable over time, producing, after application to keratin, both a uniform color and pleasant sensory properties such as the perception of a very thin film. They must not lead to pigment sedimentation, requiring the user to shake the composition before each application to re-homogenize it.

[0006] Unexpectedly, the inventors found that it is possible to achieve these objectives using a composition comprising, in particular in a physiologically acceptable environment: (1) at least one polyphenol comprising at least two different phenol groups, and (2) at least one aqueous dispersion of wax particles (3) at least one non-ionic surfactant with an HLB greater than or equal to 8; and (4) at least one uncoated iron oxide type pigment.

[0007] The inventors also discovered that said polyphenol and said non-ionic surfactant of HLB greater than or equal to 8 interacted by hydrogen bonds to form a coating agent on the keratin material.

[0008] This discovery is the basis of the invention. Objects of the invention

[0009] Thus, a first object of the present invention is a composition comprising, preferably in a physiologically acceptable medium, at least: (1) at least one polyphenol comprising at least two different phenol groups, and (2) at least one aqueous dispersion of wax particles; and (3) at least one non-ionic surfactant with an HLB greater than or equal to 8; and (4) at least one uncoated iron oxide type pigment.

[0010] According to a preferred embodiment of the invention, the composition does not contain a water-soluble or water-dispersible thickening polymer.

[0011] A second object of the present invention is a method of coating keratinous materials consisting of applying to the surface of said materials at least one composition as defined above.

[0012] In the context of the present invention, "keratinous material" includes, in particular, skin such as the face, body, hands, cheeks, eyelids, and the area around the eyes, as well as keratinous fibers such as eyelashes, eyebrows, and hair such as beard hair. The term "keratinous material," as used in the present invention, also extends to synthetic false eyelashes and eyebrows.

[0013] By "physiologically acceptable" is meant compatible with the skin and / or its appendages, which has a pleasant color, odor and feel and which does not generate no unacceptable discomforts (tingling, pulling), likely to deter the consumer from using this composition.

[0014] By "composition not containing water-soluble or water-dispersible thickening or gelling polymer", we mean any composition containing less than 0.1% by weight relative to the total weight of the composition or even free of water-soluble or water-dispersible thickening polymer.

[0015] By "polymer" is meant any molecule comprising in its structure at least one chain formed by at least two identical motifs (monomers), preferably at least 3.

[0016] By "thickening polymer" is meant any polymer capable of increasing the viscosity of the composition.

[0017] By "ambient temperature", we mean 25°C.

[0018] By “atmospheric pressure”, we mean 760 mm of Hg or 101,325 Pascals.

[0019] For the purposes of this invention, "hydrogen bonding interaction" means an interaction involving a hydrogen atom from one of the two reactants and an electronegative heteroatom from the other reactant, such as oxygen, nitrogen, sulfur, and fluorine. In the context of this invention, hydrogen bonds are formed between the hydroxyl (OH) groups of the reactive phenol groups of the polyphenol and the reactive groups (e.g., hydroxyl and / or ethers) of the nonionic surfactant with an HLB greater than or equal to 8, capable of forming hydrogen bonds with those of said phenol groups of the polyphenol.

[0026] Among the natural polyphenols that can be used according to the invention, lignins can also be mentioned.

[0027] Examples of non-flavonoids include curcuminoids such as curcumin or tetrahydrocurcumin; stilbenoids such as astringin, resveratrol or rhaponticin; aurones such as aureusidine; and mixtures thereof.

[0028] Other polyphenols that can be used according to the invention include chlorogenic acid, verbascoside; and coumarins substituted by phenols.

[0032] According to a particular embodiment of the invention, polyphenol X is tannic acid as the commercial product sold under the name Brewtan F® by the company Anijomoto Omnichem Nv.

[0033] Tannic acid will be used more particularly as a polyphenol.

[0034] According to a particular embodiment, the polyphenol(s) of the invention is (are) present in an amount greater than or equal to 0.8% by weight, preferably greater than or equal to 1.0% by weight, and more particularly greater than or equal to 2.0% by weight relative to the total weight of the composition.

[0035] According to a particular embodiment, the polyphenol(s) of the invention (is) present in an amount ranging from 1.0 to 30.0% by weight, and more particularly ranging from 2.0 to 30% by weight relative to the total weight of the composition. Aqueous dispersion of wax particles

[0036] The composition according to the invention comprises at least one aqueous dispersion of wax.

[0037] By aqueous dispersion of wax particles, we mean an aqueous dispersion of wax particles, in which the average size of said wax particles is less than or equal to 30 microns, preferably less than or equal to 10 microns, or even less than or equal to 5 microns.

[0038] According to a particular mode, the particles of the wax dispersion have average dimensions less than or equal to 1 pm, in particular ranging from 0.02 pm to 1 pm.

[0039] The sizes are measured by static light scattering using a commercial particle size analyzer, specifically the Malvern MasterSizer 3000®, which allows for the determination of the particle size distribution across a wide range from 0.01 pm to 1000 pm. The data are processed based on the classical Mie scattering theory. This theory is best suited for size distributions ranging from submicron to multimicron and allows for the determination of an "effective" particle diameter. This theory is notably described in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0040] D

[50] represents the maximum size that 50% of the particles have by volume.

[0041] In the present application, a wax is a lipophilic compound, solid at room temperature (25 °C), with a reversible solid / liquid phase change, having a melting point greater than or equal to 30 °C and up to 120 °C. By bringing the wax to a liquid state (melting), it is possible to make it miscible with oils and to form a microscopically homogeneous mixture, but by returning the temperature of the mixture to room temperature, the wax recrystallizes in the oils of the mixture.

[0042] The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example, the calorimeter sold under the name DSC by METLER. A 15 mg sample of the product placed in a crucible is first heated from 0 °C to 120 °C at a rate of 10 °C / minute, then cooled from 120 °C to 0 °C at a rate of 10 °C / minute, and finally heated a second time from 0 °C to 120 °C at a rate of 5 °C / minute. During the second heating, the change in the difference in power absorbed by the empty crucible and by the crucible containing the product sample is measured as a function of temperature. The melting point of the compound is the temperature value corresponding to the peak of the curve representing the change in the difference in power absorbed as a function of temperature.

[0043] Aqueous wax dispersions are stable dispersions of colloidal wax particles, and are described in particular in "Microemulsions Theory and Practice", LM Prince Ed., Academie Press (1977) pages 21-32.

[0044] Aqueous wax dispersions are also described in application EP0394078 as well as their preparation processes.

[0045] In particular, these wax dispersions can be obtained by melting the wax in the presence of a surfactant, and optionally some water, followed by the gradual addition of hot water with stirring. An intermediate formation of a water-in-oil emulsion is observed, followed by a phase inversion with the final formation of an oil-in-water emulsion. Upon cooling, a stable dispersion of solid colloidal wax particles is obtained. Wax dispersions can also be obtained by stirring the mixture of wax, surfactant, and water using stirring means such as ultrasound, high-pressure homogenizers, or turbines.

[0046] These particles are made of a wax or a mixture of waxes.

[0047] The wax or waxes used in the compositions of the invention are preferably polar.

[0048] By "polar wax" is meant waxes comprising in their chemical structure, in addition to carbon and hydrogen atoms, at least one strongly electronegative heteroatom, such as O, N or P.

[0049] They may, however, include in a minority proportion oily and / or pasty fatty additives and / or a common fat-soluble additive / active ingredient.

[0050] The polar waxes that can be used in the compositions according to the invention are chosen from solid and rigid waxes at room temperature of animal, vegetable, mineral or synthetic origin and mixtures thereof. Preferably, the waxes entering into the composition have a melting point above 45°C, and in particularly above 60°C. The wax can also have a hardness ranging from 0.05 MPa to 15 MPa, and preferably from 6 MPa to 15 MPa. Hardness is determined by measuring the compressive strength at 20°C using the texture tester sold under the name TA-TX2i by RHEO, equipped with a 2 mm diameter stainless steel cylinder moving at a measurement speed of 0.1 mm / s and penetrating the wax to a depth of 0.3 mm. To perform the hardness measurement, the wax is melted at a temperature equal to the wax's melting point + 20°C. The molten wax is poured into a container 30 mm in diameter and 20 mm deep. The wax is recrystallized at room temperature (25°C) for 24 hours, then stored for at least 1 hour at 20°C before the hardness measurement is taken. The hardness value is the measured compressive force divided by the surface area of ​​the texture tester cylinder in contact with the wax.
