Description

Composition with good-looking effect The invention relates to compositions

  topical use, including encapsulated pigments, and their use for the care of the skin and in particular to homogenize the complexion.

  Currently to have on the homogeneity of the complexion, it is necessary to use products which are colored in the mass. However, these products are not synonymous with care products for consumers but they are considered makeup products, and some consumers do not have the time, the desire, the dexterity or even do not always find practical, the superposition of several products, that is to say the application of a care product and a makeup product.

  To differentiate both conventional skincare products and make-up products, it has been sought to have a care product which is not colored but which nevertheless can give a uniform complexion when it is applied to the skin, and whose appearance differentiates both that of care products and that of makeup products.

  The Applicant has found the possibility of obtaining such compositions by combining encapsulated pigments in a specific composition in which these encapsulated pigments remain homogeneously distributed in the composition, and appear in the form of grains visible to the naked eye.

  Thus, the present application relates to a composition for topical application comprising an emulsion and pigments (organic pigments or dyes which are organic pigments) encapsulated having a size ranging from 100 to 1000 pm, dispersed in the emulsion, the emulsion having the colorimetric coordinates in the space L *, a *, b * in light D65: L * between 80 and 100 a * between -15 and +10 b * between -10 and +30.

  By emulsion is meant a composition which comprises at least one aqueous phase and at least one oily phase.

  The colorimetric coordinates are measured on the emulsion when it does not contain the encapsulated pigments.

  The encapsulated pigments for their part have the colorimetric coordinates in the space L *, a *, b * in light D65: L * between 15 and 60 a * between -20 and +70 b * between -50 and + 95.

  Colorimetric measurements L *, a * and b * can be performed using a MINOLTA CHROMAMETER CR400 colorimetric.

  To make the measurements, the test composition is introduced into a pot of 15 ml volume (opening diameter: 3.1 cm, depth: 1.8 cm). The surface of the introduced composition is smoothed by leveling with a glass slide. The colorimeter cell is then brought into contact with this surface and the colorimetric parameters are determined. The emulsions according to the invention are characterized by a clarity L * ranging from 8 to 100, associated with a * ranging from -15 to +10 and b * ranging from -10 to +30.

  The present invention also relates to a composition for topical application in emulsion form comprising at least one aqueous phase and at least one oily phase, comprising encapsulated pigments, said composition comprising an amount of oily phase which is equal to or less than 25% of the total weight of the composition when the emulsion is an oil-in-water emulsion (O / W), and which is equal to or less than 15% of the total weight of the composition when the emulsion is a water-emulsion emulsion. oil (W / O), said composition being free of self-tanning agent and melanogenesis activator,

  The claimed composition is for topical application. By topical application is meant here an external application on keratin materials, and in particular the skin. Since the composition is intended for topical application, it comprises a physiologically acceptable medium. Physiologically acceptable medium means a medium compatible with keratin materials, that is to say the skin, the lips, the scalp, the eyelashes, the eyes, the nails and / or the hair. The composition may constitute in particular a cosmetic or dermatological composition.

  The composition according to the invention can be used in particular for the care of the skin and in particular to homogenize the complexion of the skin. This composition has a double valence: it constitutes at the same time a product of care by bringing for example a hydrating effect, an anti-aging effect, or any other effect of care, and a make-up product by bringing an immediate effect on the homogeneity of the complexion.

  The present application also relates to a cosmetic process for homogenizing the complexion of the skin, comprising applying to the skin, an effective amount of a composition as defined above. Generally, the effective amount of composition applied to the skin is 0.5 to 4 mg / cm 2, more preferably 1 to 3 mg / cm 2, and most preferably 1 to 2 mg / cm 2.

  The present application also relates to the cosmetic use of a composition as defined above, for the care and / or treatment of the skin. Encapsulated pigments Pigments can be all of the same color or can be of different colors, the capsules can contain pigments of the same color or pigments of different colors. In the present application, the term "encapsulated pigments" means pigments which are contained in capsules constituting a shell around the pigment or pigments. As indicated above, the capsules may contain only one kind of pigments and therefore only one color, or several kinds of pigments. The encapsulated pigments have different properties of the coated pigments because they are physically separated from the composition and therefore can not interfere with the other compounds of the composition, whereas this is not the case with coated pigments. These encapsulated pigments are in the form of visible grains and have a size, that is their number average diameter, ranging from 100 to 1000 μm, preferably from 250 to 850 μm. They have the distinction of being of a different color than that of the composition containing them, and to be clearly visible in the composition. The fact that they are visible has the advantage of clearly distinguishing them from the care emulsion and therefore preserving the care characteristics of the product. The pressure exerted during the application of the composition on the skin breaks the capsules, and thus allows the release of the pigment or pigments, imparting color to the skin. The pigments that are encapsulated may be chosen from inorganic pigments and organic pigments, interferential or not, surface-treated or untreated, and mixtures thereof. A pigment is any coloring matter insoluble in cosmetic raw materials known to those skilled in the art. They can be alone (one color) or mixed. The pigments can be of any color, including yellow, black, red, brown, blue and purple.

  Mention may in particular be made, as inorganic pigments, of titanium dioxide, zirconium oxides, cerium oxides, zinc oxides, iron oxides (black, yellow or red), chromium oxides, manganese violet , ultramarine blue, chromium hydrate and ferric blue. All these pigments can be optionally treated or surface-coated.

  Among the organic pigments, mention may be made of carbon black, organic lacquer-type pigments of barium, strontium, calcium or aluminum including those subject to certification by the Food and Drug Administration (FDA) (examples D & C or FD & C) and those exempt from FDA certification as lacquers based on cochineal carmine. The pigments are encapsulated in capsules that must be both flexible and resistant. Thus, they must be resistant to other raw materials present in the composition but flexible enough to be able to break under shear during application to the skin and thus deliver the expected color. These capsules may be in particular of a material which may be chosen from: jojoba esters, cellulose derivatives such as hydroxypropyl methylcellulose, and mixtures containing them, and mixtures thereof.

  As pigments encapsulated by jojoba esters capsules, mention may be made, for example, of the spheres marketed by Floratech (Spheres of jojoba esters) under the trade names Florasomes and described in document US-A-6,432,428, such as those sold under the name US Pat. name Florasomes Jojoba SMS 20% Pigment Custom Brown # 499c.

  Cellulose capsule-encapsulated pigments include, for example, spheres comprising mannitol, cellulose, hydroxypropyl methylcellulose, marketed by Induchem.

  Several types of capsules containing encapsulated pigments made of different encapsulation materials can also be used in the same composition. The percentage of pigments relative to the total weight of the encapsulated pigment (weight of the encapsulated pigment = weight of the capsule + weight of the pigments) can vary to a large extent. The amount of pigments may range, for example, from 10 to 80% by weight, preferably from 20 to 60% by weight and better still from 20 to 50% by weight relative to the total weight of the encapsulated pigment. The composition according to the invention may contain a quantity of encapsulated pigments (weight of the capsule + weight of the pigments) ranging, for example, from 0.01 to 20% by weight, preferably from 0.05 to 15% by weight, better from 0.1 to 10% by weight and more preferably from 0.5 to 5% by weight relative to the total weight of the composition. Emulsion The emulsion before incorporation of the pigments is a white composition having the colorimetric characteristics in the space L *, a *, b * in light D65: L * between 80 and 100 a * between -15 and +10 b * between -10 and +30.

  It is preferably free of skin coloring agents such as self-tanning agents and melanogenesis activators, in particular free of dihydroxyacetone (DHA). The emulsion according to the invention may be more or less fluid and preferably has the appearance of a white cream or an emulsified gel. According to a preferred embodiment, the emulsion has a viscosity greater than 3 poise (0.3 Pa. $), Measured at 25 ° C. with Rheomat 180 with a mobile adapted to the viscosity (generally 3 or 4), preferably a rotation speed of 200 rpm.

  It may be a water-in-oil emulsion (W / O) or an oil-in-water (O / W) emulsion or a multiple emulsion. According to a preferred embodiment of the invention, when the emulsion is an O / W, the percentage of oily phase is preferably less than or equal to 25% of the total weight of the composition (emulsion + pigments) and when the emulsion is an W / O, the percentage of oily phase is preferably less than or equal to 15% of the total weight of the composition.

  The term "oily phase" is understood here to mean the phase containing all the lipophilic compounds, that is to say the oils and other fatty substances, the lipophilic surfactants, the other lipophilic compounds such as active ingredients and lipophilic polymers.

  In addition, it is advantageous for the oils to have a specific polarity which differs depending on the direction of the emulsion. In the O / W emulsions, the mixture of the oils preferably has an overall polarity (8a) 2, 4 and in the W / O emulsions, the mixture of the oils preferably has an overall polarity (8a) of 1.4, ( 8a) being the average parameter reflecting the polarity calculated according to the Hansen solubility parameter theory.
