Description

Technical Field

[0001] This invention relates to the field of cosmetics, and more particularly to solid cosmetic compositions for use in the care and / or makeup of skin, eyelids, eyebrows or lips. Background Technology

[0002] Solid, waterless care and / or cosmetic products for the skin or lips are sought after by consumers for their coverage and long-lasting properties.

[0003] Opacity is typically provided by white pigments and / or fillers, and titanium dioxide is widely used due to its high opacity and high opacity. However, there is a growing demand for alternatives to titanium dioxide, and the applicant has observed that zinc sulfide particles can yield anhydrous solid compositions with good opacity, good rod-like mechanical properties, and good applicability and sensory properties. Summary of the Invention

[0004] Therefore, a first aspect of the present invention is a solid care and / or cosmetic composition for keratin materials, particularly for skin, eyelids, eyebrows, or lips, said composition comprising, in a physiologically acceptable medium: (i) Zinc sulfide particles, preferably zinc sulfide particles encapsulated and / or surface-treated with hydrophilic and / or lipophilic treatment agents, (ii) one or more oils, and (iii) One or more aliphatic phase structuring agents.

[0005] The term "cosmetic composition" means any composition intended for cosmetic purposes (i.e., aesthetic purposes) that can come into contact with the surface parts of the human body, more particularly with keratinized materials, especially with human skin and / or lips.

[0006] The term "physiologically acceptable medium" means any excipient suitable for topical application that poses no risk of toxicity, incompatibility, instability, or allergic reactions when in contact with keratinous materials.

[0007] The term "keratinous material" according to the invention refers to skin and / or its appendages, more particularly human skin and / or lips. Specifically, it relates to the skin of the face and / or neck and / or body, and the lips. In the context of the invention, keratinous material is healthy, i.e., does not exhibit a disease or condition that is part of a pathological condition ("unhealthy" subject, subject suffering from a pathological condition). Throughout this specification, healthy skin and / or lips, or skin and / or lips, may be used interchangeably.

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

[0009] The present invention also relates to a cosmetic method for caring for and / or applying keratin materials, particularly for skin, eyelids, eyebrows or lips, preferably lips, comprising applying the composition of the present invention to the keratin material. Detailed Implementation

[0010] Therefore, the present invention relates to keratin materials, particularly solid care and / or cosmetic compositions for skin, eyelids, eyebrows, or lips, said compositions comprising, in a physiologically acceptable medium: (i) Zinc sulfide particles, preferably zinc sulfide particles encapsulated and / or surface-treated with hydrophilic and / or lipophilic treatment agents, (ii) one or more oils, and (iii) One or more aliphatic phase structuring agents.

[0011] According to a particular embodiment, the composition comprises less than 3% by weight of titanium dioxide relative to the total weight of the composition, particularly less than 1% by weight of titanium dioxide, or even contains no titanium dioxide.

[0012] In the context of this invention, the term "solid composition" means a composition that does not flow under its own weight at 20°C and atmospheric pressure (760 mm Hg), as opposed to a so-called liquid composition.

[0013] The composition may be in the form of a rod or a composition packaged in a cup.

[0014] The hardness of the compositions of the present invention (particularly rods) can be measured at 20°C using the so-called "fil àcouper le beurre" method, which involves moving a rigid metal wire with a diameter of 250 μm relative to the rod at a speed of 60 mm / min, transversely cutting product rods with a diameter between 10 and 12 mm, preferably cylindrical. The hardness of the sample is expressed in grams per force (gf) and can be measured using a texture analyzer (e.g., a TAXT Plus texture analyzer). For composition rods intended for application to the lips, the minimum value obtained is greater than 30 gf.

[0015] Those skilled in the art will be able to adjust the rod-forming method using the composition of the present invention according to its hardness. In particular, when the hardness is less than 100 gf, it is preferable to use the "back-fill" method to form the rod, which involves pouring and cooling the composition directly into the packaging assembly, rather than forming it by pouring and cooling the composition in a mold and then inserting it into the assembly.

[0016] The compositions of the present invention are preferably anhydrous compositions.

[0017] The term "anhydrous composition" specifically means that water is not intentionally added to the composition of the present invention, but may be present in trace amounts in the various ingredients used in the composition. In particular, the composition according to the invention contains less than 4% by weight, preferably less than 3% by weight, more preferably less than 2% by weight, more preferably less than 1% by weight, and even more preferably less than 0.5% by weight of water relative to the total weight of the composition, or even no water at all. In one particular embodiment, the composition is water-free.

[0018] The composition of the present invention comprises zinc sulfide particles.

[0019] Zinc sulfide (ZnS) granules Zinc sulfide granules are in powder form, usually white, and partially insoluble in water.

[0020] The zinc sulfide (ZnS) particles used in this invention differ from interference pigments that comprise a non-ZnS carrier and at least one surface ZnS layer. They also differ from phosphorescent (photoluminescent) pigments, which comprise ZnS pigments activated by a metal (e.g., copper or silver) (also known as metal-doped pigments).

[0021] Therefore, according to the present invention, the term "zinc sulfide particles" refers to white particles, which are different from interference pigments or phosphorescent (photoluminescent) pigments.

[0022] The average size of the zinc sulfide particles used in this invention is typically 0.1 to 10 μm (micrometers), particularly 0.1 to 5 μm, or even 0.1 to 2 μm.

[0023] The size of the particles can be measured using laser diffraction particle size distribution method with a Malvern Mastersizer type device, in particular by measuring the D

[50] value, which represents the maximum size of 50% of the particle volume.

[0024] Advantageously, the powder contains at least 50% of particles with a diameter of 0.1 μm as observed by scanning electron microscopy (MEB).

[0025] Advantageously, the powder consists of zinc sulfide particles that are substantially spherical or oval in shape.

[0026] Zinc sulfide sold by ZEHAO, VENATOR, and TAIZHOU ATS may be specifically mentioned.

[0027] The zinc sulfide particles used according to the invention are preferably encapsulated and / or surface-treated with a treatment agent, particularly with a hydrophilic treatment agent (e.g., silica) and / or a lipophilic treatment agent (e.g., N-acylated amino acids or their salts, dextrin esters, organosilicon reagents, metal soaps, lecithin and its derivatives, waxes, fatty esters and phospholipids). In a particular embodiment, the zinc sulfide particles are treated with at least silica.

[0028] These treatments render the zinc sulfide particles inert and / or allow for better dispersion of the treated particles in the fatty phase of the compositions of the present invention. They are also intended to protect the zinc sulfide particles from any contact with solvent media during composition preparation and when the composition is applied to the skin.

[0029] In a particular and preferred embodiment, the zinc sulfide particles are treated with silica and / or a lipophilic treatment agent.

[0030] Silica treatment is carried out by any method known to those skilled in the art, and advantageously by anhydrous methods.

[0031] According to another particular and preferred embodiment, the zinc sulfide particles are treated sequentially with silica and then with a lipophilic treatment agent.

[0032] According to another particular embodiment of the invention, the zinc sulfide particles are untreated and have the INCI name ZINCSULFIDE.

[0033] According to another particular embodiment, the zinc sulfide particles are treated with a lipophilic treatment agent. As a "lipophilic treatment agent" that can be used according to the invention, N-acylated amino acids or their salts, dextrin esters, organosilicon reagents, metal soaps, lecithin and its derivatives, waxes, fatty esters, and phospholipids may be specifically mentioned.

[0034] The applicant has conducted numerous tests to determine the hiding power of zinc sulfide particles compared to titanium dioxide, thereby enabling the substitution of titanium dioxide in formulations without compromising the desired hiding power. These results indicate that, for equivalent hiding power, an amount of zinc sulfide particles 1.1 to 2 times greater than the amount of titanium dioxide is required in the anhydrous solid composition according to the invention to achieve equivalent hiding power.

[0035] According to a particular embodiment, the content of zinc sulfide particles in the composition of the present invention is typically from 0.05% to 30% by weight of zinc sulfide relative to the total weight of the composition, particularly from 0.1% to 20% by weight of zinc sulfide, particularly from 1% to 15% by weight of zinc sulfide, preferably from 2% to 10% by weight of zinc sulfide.

[0036] 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, particularly less than 1% by weight of titanium dioxide relative to the total weight of the composition, or even contains no titanium dioxide.
