Description

Title of the invention: Solid care and / or makeup composition comprising zinc sulfide particles FIELD OF THE INVENTION

[0001] The present invention relates to the cosmetic field and in particular to solid cosmetic compositions for the care and / or makeup of keratin materials, in particular the skin, eyelids, eyebrows or lips. STATE OF THE ART

[0002] Solid anhydrous skin or lip care and / or makeup products are sought after by consumers for their coverage and hold properties.

[0003] Coverage is generally provided by white pigments and / or fillers, and titanium dioxide is generally used, which has a high opacifying and covering power. However, there is an increasing search for alternative solutions to titanium dioxide and the Applicant has observed that zinc sulfide particles make it possible to obtain an anhydrous solid composition having good covering properties, good mechanical properties of the stick and good application and sensorial properties. Statement of the invention

[0004] A first aspect of the invention is therefore a solid cosmetic composition for the care and / or makeup of keratin materials, in particular the skin, eyelids, eyebrows or lips, comprising, in a physiologically acceptable medium: i. Zinc sulfide particles, preferably encapsulated and / or surface-treated with a hydrophilic and / or lipophilic treatment agent, ii. One or more oils, and iii. One or more fatty phase structuring agents.

[0005] By "cosmetic composition" is meant any composition for cosmetic purposes, that is to say aesthetic, which can be brought into contact with the superficial parts of the human body and more particularly with keratin materials, in particular human skin and / or lips.

[0006] By "physiologically acceptable medium" is meant any excipient suitable for topical use, in contact with keratin materials, without risk of toxicity, incompatibility, instability and / or allergic response.

[0007] By "keratin materials" according to the invention, we mean the skin and / or its appendages, and more particularly the human skin and / or lips. In particular, this will be the skin of the face and / or neck and / or body, and the lips. The keratin materials in the context of the invention are healthy, that is to say not presenting any disorders or disorders that would be related to a pathological state (“unhealthy” subjects, suffering from a pathology). We will speak indifferently of healthy skin and / or lips or skin and / or lips in the rest of the description.

[0008] According to a particular and preferred embodiment, the composition of the invention is an anhydrous composition.

[0009] The present invention also relates to a cosmetic process for caring for and / or making up keratin materials, in particular the skin, the eyelids, the eyebrows or the lips, preferably the lips, comprising the application to said keratin materials of a composition as defined in the invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention therefore relates to a solid cosmetic composition for the care and / or makeup of keratin materials, in particular the skin, eyelids, eyebrows or lips, comprising, in a physiologically acceptable medium: i. Zinc sulfide particles, preferably encapsulated and / or surface-treated with a hydrophilic and / or lipophilic treatment agent, ii. One or more oils, and iii. One or more fatty phase structuring agents.

[0011] For the purposes of the present invention, the term "solid composition" means a composition which does not flow under its own weight, at 20°C and at atmospheric pressure (760 mm Hg), as opposed to so-called liquid compositions.

[0012] The composition may in particular be in the form of a stick or a composition packaged in a cup.

[0013] The hardness of the compositions of the invention, in particular the sticks, can be measured at 20°C by the so-called "butter wire cutting" method, which consists of transversely cutting a stick of product with a diameter of between 10 and 12 mm, preferably cylindrical in revolution, using a rigid metal wire with a diameter of 250 μm, moving the wire relative to the stick at a speed of 60 mm / min. The hardness of the samples is expressed in Gram force (Gf) and can be measured using a texturometer of the Texturometer TAXT Plus type. For a stick of a composition intended to be applied to the lips, the minimum value obtained is greater than 30 Gf.

[0014] A person skilled in the art will know how to adapt the method for shaping the stick from the composition of the invention according to its hardness. In particular when the hardness is less than 100Gf, shaping the stick by a so-called "back-fill" method, consisting of pouring and cooling the composition directly in the mechanism of the pack, will be preferred over shaping consisting of pouring and cooling the composition in a mold and then inserting the stick into the mechanism.

[0015] Preferably, the composition of the invention is an anhydrous composition.

[0016] By "anhydrous composition" is meant in particular that water is 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%, even more preferably less than 0.5% by weight of water, relative to the total weight of said composition, or even is completely free of water. According to a particular embodiment, the composition is free of water.

[0017] The composition of the invention comprises zinc sulfide particles. Zinc sulfide (ZnS) particles

[0018] Zinc sulfide particles are in the form of a powder, generally white in color, and are partially insoluble in water.

[0019] The zinc sulfide (ZnS) particles used according to the invention are distinct from interference pigments comprising a support which is not ZnS and at least one layer of ZnS on the surface.

[0020] The average size of the zinc sulfide particles used according to the invention will generally range from 0.1 to 10 pm (micrometers), in particular from 0.1 to 5 pm, or even from 0.1 to 2 pm.

[0021] The particle size can be measured according to a laser diffraction distribution method with a device of the Malvem Mastersizer type, in particular by measuring the D

[50] value, which represents the maximum size that 50% by volume of the particles represents.

[0022] Advantageously, the powder contains at least 50% by number of particles having a diameter of 0.1 pm by observation under a scanning electron microscope (SEM)

[0023] The powder is advantageously made up of zinc sulfide particles of essentially spherical or ovoid shape.

[0024] We can cite in particular zinc sulfides marketed by ZEHAO, VENATOR, and TAIZHOU ATS.

[0025] The zinc sulfide particles used according to the invention are preferably encapsulated and / or surface-treated with a treatment agent, in particular with a hydrophilic treatment agent, for example silica and / or a lipophilic treatment agent, such as N-acylated amino acids or their salts, dextrin esters, silicone agents, metallic soaps, lecithin and its derivatives, waxes, fatty esters, and phospholipids. According to a particular embodiment, the zinc sulfide particles are treated at least with silica.

[0026] These treatments make it possible to make the zinc sulfide particles inert and / or allow better dispersion of the treated particles in the fatty phase of the composition of the invention. It also aims to protect the zinc sulfide particle from any contact with a solvent medium at the time of manufacture of the composition but also at the time of application of the composition to the skin.

[0027] According to a particular and preferred embodiment, the zinc sulfide particles are treated with silica and / or a lipophilic treatment agent.

[0028] The treatment with silica is carried out by any method known to those skilled in the art, and advantageously by an anhydrous method.

[0029] According to another particular and preferred embodiment, the zinc sulfide particles are treated successively with silica, then a lipophilic treatment agent.

[0030] According to another particular embodiment of the invention, the zinc sulfide particles are not treated and they have the INCI name: ZINC SULFIDE.

As “lipophilic treatment agent” which can be used according to the invention, mention may in particular be made of N-acylated amino acids or their salts, dextrin esters, silicone agents, metallic soaps, lecithin and its derivatives, waxes, fatty esters, and phospholipids.

[0032] The Applicant carried out several upstream tests to determine the covering power of zinc sulfide particles, compared to titanium dioxide, in order to be able to replace titanium dioxide in formulas, without impacting the desired covering effect. These results showed that, for an equivalent covering power, in an anhydrous solid composition according to the invention, a quantity of zinc sulfide particles 1.1 to 2 times greater than the quantity of titanium dioxide was required for an equivalent covering result.

[0033] According to a particular embodiment, the content of zinc sulfide particles in the composition of the invention will generally range from 0.05% to 30% by weight of zinc sulfide, in particular from 0.1 to 20% by weight, in particular from 1% to 15% by weight of zinc sulfide, preferably from 2% to 10% by weight of zinc sulfide relative to the total weight of the composition.
