Description

Title of the invention: Solid cosmetic composition technical field

[0001] This description relates to a solid cosmetic composition based on natural or naturally derived waxes. It also relates to a preparation process and a process for the treatment or makeup of keratinous materials that uses this composition. Previous technique

[0002] Synthetic waxes are products obtained from petroleum. Paraffins constitute a first category of synthetic waxes: they are hydrocarbon compounds derived from petroleum. They have a solid to semi-solid consistency at room temperature. They are generally characterized by a melting point between 40 and 90°C, excellent oxidation and temperature stability, odor neutrality, and clarity.

[0003] Other synthetic waxes can be obtained by chemical synthesis from petroleum derivatives. These include polymers, which generally have a higher melting point than paraffins.

[0004] These properties of texture, visual appearance and olfactory neutrality make synthetic waxes products in high demand for many applications such as the manufacture of cosmetic products and in particular the manufacture of solid cosmetic products, for example poured into pots or pans or in the form of sticks.

[0005] However, the synthetic waxes currently available on the market pose problems in terms of environmental protection and safety.

[0006] Indeed, paraffins, including MOSH (mineral oil saturated hydrocarbons) and / or MOAH (mineral oil aromatic hydrocarbons), are suspected of toxicity, in particular of carcinogenic effect, so that regulations now require limiting their concentration in food products.

[0007] Furthermore, due to their origin, paraffins contribute negatively to the increase of anthropogenic carbon dioxide. In addition, synthetic waxes are not biodegradable and induce bioaccumulation in the environment.

[0008] This is why many sectors are looking for ecological, biodegradable and sustainable substitute products to replace synthetic waxes.

[0009] Natural or naturally derived waxes of vegetable or animal origin, such as beeswax, candelilla or carnauba wax, offer a renewable alternative to synthetic waxes, in particular paraffins.

[0010] In the context of the invention, an ingredient "of natural origin" means an ingredient that is either "natural" or "derived from natural" as defined below, and in accordance with the definition given by ISO 16128.

[0011] For the purposes of this application, a "natural" ingredient means an ingredient of plant or animal origin that has not undergone any chemical transformation. In the field of cosmetics, a natural ingredient may have undergone physical modifications, such as extraction by traditional mechanical means. Its naturalness index is 1, meaning that it consists solely of natural components.

[0012] For the purposes of this application, a "naturally derived" ingredient is defined as an ingredient of plant or animal origin that has undergone chemical transformations, meaning that its natural state has been altered to make it suitable for use in cosmetics. A naturalness index can be calculated for these ingredients. An ingredient will be considered "naturally derived" if its naturalness index is greater than 0.5, meaning that more than 50% of its constituent components are derived from nature. The naturalness index of an ingredient with less than 50% of its constituent components being derived from nature will be 0.

[0013] Calculating the naturalness index of an ingredient, where applicable in the presence of wax, falls within the general knowledge of a person skilled in the art. The naturalness index calculation is generally established and provided by the raw material supplier. For the same ingredient, with a given chemical structure, it is therefore possible to obtain different naturalness indices, depending on the preparation process of said ingredient.

[0014] However, in many applications, natural or naturally derived waxes cannot completely replace paraffins or other synthetic waxes.

[0015] Recent scientific work has investigated the possibility of substituting paraffins in lipstick formulations with mixtures of naturally derived lipids, specifically a mixture of linear C35-C38 alkenones from algal resources. However, low stability was observed (Huynh, A. et al. Evaluation of alkenones, a renewablely sourced, plant-derived wax as a structuring agent for lipsticks. Int. J. Cosmet. Sci. 42, 146-155 (2020)).

[0016] Other scientific studies have recently shown that in the field of lipsticks, the substitution of synthetic waxes of petroleum origin with waxes of vegetable origin poses problems of product stability, of the solidity of the lipstick, exudation, incompatibilities and / or oxidation, which increasingly demanding consumers are not prepared to deal with, (de Clermont-Gallerande et al. Substitution of synthetic waxes by plant-based waxes in lipsticks, OCL, 2022, 29, 19).

[0017] Thus, this study shows that when the composition obtained with vegetable waxes is solid, it has too low hardness values ​​which result in too frequent breakage during application in the case of sticks.

[0018] Furthermore, the stability over time is not satisfactory. This can result in the appearance of an exudation phenomenon, polymorphism, a change in the appearance of the surface of the product such as the appearance of inhomogeneities of appearance, with the presence of matte surface area(s), or film-forming area(s), or even an evolution of the sensory experience during application over time (decrease in meltability, in glide).

[0019] Furthermore, natural plant-based waxes with a high melting point, i.e., approximately 80°C, do not allow for sufficiently sensorial textures: they are very rigid, lack flexibility, and the sensation upon application to the skin or lips is unpleasant. Finally, plant-based waxes with a melting point below 80°C do not allow for sufficient structuring of the composition to mold lipsticks into sticks.

[0020] There is therefore a real need to find natural or natural-derived substitute products, in particular plant-derived, ecological and sustainable ones to replace paraffins.

[0021] A solid cosmetic composition based on natural or naturally derived ingredients, particularly plant-derived ingredients, has now been developed, whose physicochemical characteristics, including hardness, texture, and / or melting point, are very close to those obtained with existing synthetic waxes. In particular, this solid composition, free of petroleum-based synthetic waxes, does not present problems of stability, strength (i.e., excessive breakage in the case of sticks), exudation, incompatibilities, and / or oxidation.

[0022] Thus, according to a first aspect, the invention relates to a solid cosmetic composition comprising: - a lipophilic gelling agent selected from functionalized castor oils, in particular a castor oil polymer functionalized with isophorone diisocyanate, and - at least 3.5% by weight of at least one natural wax or wax derived from natural sources; - at least one non-volatile polar oil; - less than 3% by weight of mineral and / or synthetic wax, preferably less than 1% by weight of mineral and / or synthetic wax, preferably the composition being free of mineral and / or synthetic wax, the percentages being expressed in relation to the total weight of the solid cosmetic composition. SOLID

[0023] According to the invention, the term "solid composition" refers to a composition exhibiting, at a temperature of 20°C and atmospheric pressure (760 mm Hg), a hardness greater than 30 Nm-1, preferably greater than 40 Nm-1, and preferably between 55 Nm-1 and 315 Nm-1. The hardness can be measured at 20°C using the "butter cutter" method, which assesses the firmness of a lipstick by measuring, in particular, its resistance to cutting the product into a stick. This measurement is performed 24 hours after formulation, using a texture analyzer (TAXTPlus, MicroStable Systems, UK) equipped with a 5 kg force cell and its Butter Cutter A / BC probe (Swantech, MicroStable Systems, UK). It allows the maximum resistance force of the stick during the penetration of the butter-cutting wire to a depth of 9 mm at a speed of 1.6 mm / s.To ensure the reproducibility of the measurements, the analysis is repeated on 6 sticks, and the relative difference between measurements must not exceed 10%, ideally 5%. For each type of product, a reference (target) range is established to guarantee the mechanical properties of the stick. For example, for a stick with a diameter of 12.7 mm (0.0127 m), a hardness expressed in Nm-1 is calculated by multiplying the hardness expressed in grams by a factor of 0.01 (where 1 g = 0.01 N) and dividing the result by the diameter 0.0127 m.

[0024] The solid composition according to the invention will generally have a hardness greater than or equal to 50g for a stick in a guided pack, because the latter has its base held in the packaging when the user uses it and it therefore resists breakage more during use.

[0025] The solid composition according to the invention will generally have a hardness greater than or equal to 70g, in particular greater than or equal to 90g, for example ranging from 100g to 400g, and preferably ranging from 140g to 300g and even more preferably ranging from 175g to 250g for a stick in an unguided pack.

[0026] Such compositions (corresponding in particular to cast sticks in a standard format of approximately 12.7 mm) exhibit adequate stability and hardness: the stick is sufficiently rigid and solid, does not break during application, and is thus compatible with packaging in stick form or another solid form and with application by friction on the surface to be treated and / or made up; they They are also characterized by ease of application such as good glide, good deposit from the first application and a comfortable texture.

[0027] The solid cosmetic composition may in particular be in the form of a stick or a composition packaged in a cup.

[0028] The solid cosmetic composition may be a skincare cosmetic composition of keratinous materials, a perfumer, or a makeup composition of keratinous materials. ANHYDROUS

[0029] Preferably the solid cosmetic composition of the invention is anhydrous.

[0030] 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 may comprise 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 may even be completely free of water. According to a particular embodiment, the composition is free of water.

[0031] POLYMERIC LIPOPHILIC GELDING AGENT DERIVED FROM CASTOR OIL

[0032] The term "lipophilic gelling agent" according to the invention means a compound capable of gelling the oil phase of a composition. The term "polymeric lipophilic gelling agent" means a polymer capable of gelling the oil phase of a composition, said polymer being defined as a relatively large molecule, in particular with a weight-average molecular weight of 2,000 daltons or more, composed of the reaction products of smaller repeating chemical units. The term "oil phase" means lipophilic compounds such as oils, waxes, butters, and pastes.

[0033] According to a particular embodiment, the composition of the invention comprises at least one castor oil polymer functionalized with isophorone diisocyanate. Preferably, the castor oil is of natural origin, otherwise known as 'bio-based'. The naturally sourced castor oil has the following composition, shown in Table 1:

[0034] Table 1: Oleic acid 7.4% Linoleic acid 3.1% Linolenic acid 1.9% Ricinoleic acid 87.0% Dihydroxystearic acid 0.6% Total 100%

[0035] The lipophilic gelling agent selected from the functionalized castor oils obtained exhibits improved adhesion properties on keratinous materials, film-forming properties and stability.

[0036] One example is the castor oil polymer functionalized with isophorone diisocyanate. It has a naturalness index of 0.91. While not bound by any specific theory, the inventors believe that the gel formation is based on supramolecular chemistry: the polymer molecules associate with each other through hydrogen bonds. These bonds are weak and reversible.

[0037] Such a castor oil polymer functionalized with isophorone diisocyanate can be obtained according to the following chemical reaction described in US patent 5707612: | O OH I 8 I : That OH | I

[0038] The stoichiometric use of two moles of castor oil for one mole of isophorone diisocyanate gives a preferred embodiment indicated above.

[0039] The lipophilic gelling agent is marketed by ALZO INC. under the trade name POLYDERM PPLCCO®. Its chemical name is castor oil polymer with 3-isocyanatomethyl-3,5,5-trimethylcyclohexyl isocyanate and its INCI name is Castor oil / IPDI Copolymer with a CAS number 68955-90-8.

[0040] The lipophilic gelling agent with the INCI name: CASTOR OIL / IPDI COPOLYMER or & CASTOR OIL / IPDI COPOLYMER, CAPRYLIC / CAPRIC TRIGLYCERIDE, is marketed under the name ESTOGEL E® or ESTOGEL M® by the company POLYMEREXPERT, preferably ESTOGEL M®. It is a lipophilic gelling agent, more than 90% bio-based, intended for polar to medium-polar oils.

[0041] The composition of the invention shall generally comprise from 0.9% to 50%, in particular 2% to 40%, preferably even from 4% to 12% by weight of the functionalized lipophilic gelling agent, the percentages being expressed by weight relative to the total weight of the composition. WAXES

[0042] The term "wax" refers to a lipophilic fatty compound, solid at room temperature (15-25 °C) and atmospheric pressure (760 mmHg), whose solid / liquid phase change is reversible. Waxes generally have a melting point above 30 °C (which can reach up to 200 °C) and exhibit an anisotropic crystalline structure in the solid state. At its melting point, the wax becomes miscible with oils and can form a microscopically homogeneous mixture. When the mixture is cooled to room temperature, the wax can be recrystallized in the oils of the mixture. NATURAL WAXES OR WAXES DERIVED FROM NATURAL PRODUCTS

[0043] Advantageously, the waxes used in the composition according to the invention are natural or natural waxes, solid at room temperature (i.e. at a temperature ranging from 15 to 25°C approximately).

[0044] In the context of the invention, waxes of natural origin are selected from natural or naturally derived waxes. As previously defined, natural or naturally derived waxes are waxes of vegetable or animal origin. In particular, mineral waxes are not natural or naturally derived waxes within the meaning of this application.

[0045] Naturally derived ingredients may be cosmetic ingredients obtained through defined chemical and / or biological processes aimed at chemically modifying them. They may be chemical compounds or chemical substances produced by a living organism, i.e., found in nature. For the purposes of this invention, ingredients of natural origin are considered to include ingredients such as waxes, butters, or oils derived from plants, or products resulting from the hydrogenation or esterification of naturally derived oils, preferably of vegetable origin.

[0046] The combination of natural or naturally derived waxes according to the invention makes it possible to structure the composition, in particular hot-poured solid compositions in stick form, in a cup, or in any type of container. The waxes used in the compositions according to the invention may be hydrocarbon-based. The waxes used in the compositions according to the invention are of natural origin, preferably of vegetable origin.

[0047] By "derived from" is meant an ingredient that has undergone a chemical modification.

[0048] The natural or naturally derived waxes used in the compositions according to the invention can be obtained from the hydrogenation of oils of natural origin, preferably vegetable such as castor oil (The wax of natural origin is then hydrogenated castor oil).

[0049] In particular, the natural or naturally derived waxes used in the compositions according to the invention have a melting point above 55°C, preferably between 58°C and 95°C, preferably between 58°C and 92°C at atmospheric pressure.

[0050] In particular, the wax of natural origin may be chosen from the group including beeswax, sunflower wax, carnauba wax, candelilla wax, cottonseed wax, rice bran wax, berry wax, Chinese insect wax, kapok wax, sugar cane wax, jojoba wax, shellac wax, the wax derived from nature may be chosen from the group including lanolin and its alcohol derivatives, acetylated, esterified, polyethoxylated natural waxes or a mixture thereof.

[0051] Naturally derived waxes may also be vegetable ester waxes selected from the group comprising the mixture of jojoba esters, polyglycerin-3, Acacia decurrens flower wax, and sunflower seed wax, said mixture being marketed by Gattefosse under the trade name Acticire®; the mixture of sunflower wax and hydrogenated castor oil marketed by Brasca under the trade name ABWAX REVOWAX; jojoba esters marketed by Floratech under the trade names Floraesters 60 or Floraesters 70; alkyl esters or hydrogenated alkyl esters marketed by Sophim under the trade name Phytowax, such as, for example, hydrogenated lauroyl oleate esters marketed under the name Phytowax Olive 12L44; and tribehenin marketed by Croda under the trade name Syncrowax. HRC-PA(RB).

[0052] In a particular embodiment, the natural or naturally derived wax of vegetable origin may be chosen from:

[0053] - sunflower wax alone or combined with hydrogenated castor oil, or

[0054] - candelilla wax

[0055] or a mixture thereof.

[0056] For example, the naturalness index of sunflower wax is 1, the naturalness index of candelilla wax is 1, the naturalness index of sunflower wax combined with castor oil is 0.99.

[0057] The mixture may therefore include sunflower wax combined with hydrogenated castor oil, sunflower wax combined with candelilla wax, candelilla wax combined with hydrogenated castor oil or sunflower wax combined with hydrogenated castor oil and candelilla wax.

[0058] In a particular embodiment, sunflower wax alone or combined with hydrogenated castor oil, candelilla wax or one of their mixtures represents between 50% and 99%, preferably between 70% and 99% and even more preferably between 80% and 99% by weight of said mixture relative to the total weight of wax(s).

[0059] When the solid cosmetic composition is in the form of a product poured into a cup, it may comprise from 3.5% to 12% by weight, preferably between 4% and 6% by weight of at least one natural or naturally derived wax according to the invention, relative to the total weight of the composition.

[0060] When the solid cosmetic composition is in the form of a stick, it may comprise from 3.5% to 20% by weight, preferably between 7% and 17% by weight of at least one natural or naturally derived wax according to the invention, relative to the total weight of the composition.

[0061] Preferably the total wax content is between 7% and 20%, preferably between 8% and 18% and more preferably between 10% and 14% by weight, relative to the total weight of the solid cosmetic composition.

[0062] In a particular embodiment, the composition of the invention has a weight ratio between the lipophilic gelling agent / natural or natural wax, preferably of vegetable origin, of between 0.01-2, preferably between 0.1 to 1 and, more preferably, between 0.5-0.7, for example around 0.67.

[0063] The solid cosmetic compositions according to the invention may further comprise other ingredients, in particular additional solid fats, especially pasty fats. MINERAL OR SYNTHETIC WAX

[0064] Preferably, the solid cosmetic compositions according to the invention comprise less than 3% by weight of mineral and / or synthetic wax, in particular less than 1% by weight, the percentages being expressed by weight relative to the total weight of the composition, and even better the composition is free of mineral and / or synthetic wax.

[0065] By "synthetic wax" is meant a wax that is not natural or derived from nature.

[0066] Among the mineral waxes, we can mention in particular montan wax, ceresins, ozokerites, microcrystalline waxes, mineral paraffins.

[0067] Among synthetic waxes, we can mention in particular:

[0068] - synthetic beeswax, such as for example those marketed by Koster Keunen under the trade name Kester Wax K82H, or one of their mixtures;

[0069] - polyethylene wax, such as that marketed by New Phase Technologies under the name Performalène 400 (P400) or by Jeen International Corporation under the name Jeenate 3H,

[0070] - a mixture of high molecular weight linear polyethylene and copolymer ethylene / propylene, marketed by Safi-Alcan under the trade name Lipwax® PZ80-20,

[0071] - a synthetic wax such as that marketed by Sasol under the name Sasol Wax C80;

[0072] - mixtures of synthetic waxes and vegetable waxes, such as for example a mixture of synthetic wax and carnauba wax (Copernica cerifera) marketed by Strahl & Pitsch under the name Smart wax 202, a mixture of synthetic wax, Candelilla wax and carnauba wax (Copernica cerifera) marketed by Strahl & Pitsch under the name Smartwax 7743S,

[0073] - Fischer Tropsch waxes such as those marketed by Cirebelle under the name Cirebelle 303, or one of their mixtures. PASTY

[0074] The solid cosmetic compositions according to the invention may include an additional pasty fatty substance.

[0075]

[0076] By "pasty fat" in the context of the present invention, we mean a lipophilic fatty compound with reversible solid / liquid phase change having in the solid state an anisotropic crystalline organization, and comprising at a temperature of 23 °C a liquid fraction and a solid fraction.

[0077] In other words, the initial melting temperature of the pasty fat can be below 23°C. The liquid fraction of the pasty fat measured at 23°C can represent 9 to 97% by weight of the pasty fat. This liquid fraction at 23°C preferably represents between 15 and 85%, and even more preferably between 40 and 85% by weight.

[0078] For the purposes of this invention, the melting point corresponds to the temperature of the most endothermic peak observed in dynamic thermal scanning (DSC) as described in ISO 11357-3; 1999. The melting point of a pasty fat can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name "MDSC 2920" by TA Instruments.

[0079] The measurement protocol is as follows:

[0080] A 5 mg sample of pasty fat placed in a crucible is subjected to The crucible is first heated from -20 °C to 100 °C at a rate of 10 °C / minute, then cooled from 100 °C to -20 °C at a rate of 10 °C / minute, and finally subjected to a second heating from -20 °C to 100 °C at a rate of 5 °C / minute. During this second heating, the difference in power absorbed by the empty crucible and the crucible containing the pasty fat sample is measured as a function of temperature. The melting point of the pasty fat is the temperature value corresponding to the peak of the curve representing the difference in power absorbed as a function of temperature.

[0081] The liquid fraction by weight of the pasty fat at 23 °C is equal to the ratio of the enthalpy of fusion consumed at 23 °C to the enthalpy of fusion of the pasty fat. The enthalpy of fusion of the pasty fat is the enthalpy consumed by the fat to change from a solid to a liquid state. The pasty fat is said to be in a solid state when its entire mass is in crystalline solid form. The pasty fat is said to be in a liquid state when its entire mass is in liquid form.

[0082] The enthalpy of fusion of the pasty fat is equal to the curve of the thermogram obtained using a differential scanning calorimeter (DS C), such as the calorimeter sold under the name MDSC 2920 by TA instrument, with a temperature rise of 5 or 10 °C per minute, according to ISO 11357-3:1999.

[0083] The enthalpy of fusion of the pasty fat is the amount of energy required to change the pasty fat from a solid to a liquid state. It is expressed in J / g.

[0084] The enthalpy of fusion consumed at 23 °C is the amount of energy absorbed by the sample to pass from the solid state to the state it presents at 23 °C consisting of a liquid fraction and a solid fraction.

[0085] The liquid fraction of the pasty fat measured at 32 °C preferably represents 30 to 100% by weight of the pasty fat, preferably 50 to 100%, and preferably 60 to 100% by weight of the pasty fat. When the liquid fraction of the pasty fat measured at 32 °C is equal to 100%, the temperature at the end of the melting range of the pasty fat is less than or equal to 32 °C.

[0086] The liquid fraction of the pasty fat measured at 32 °C is equal to the ratio of the enthalpy of fusion consumed at 32 °C to the enthalpy of fusion of the pasty fat. The enthalpy of fusion consumed at 32 °C is calculated in the same way as the enthalpy of fusion consumed at 23 °C.

[0087] The pasty fat is preferably chosen from synthetic fats and fats of vegetable origin. A pasty fat can be obtained synthetically from starting materials of vegetable origin.

[0088] A compound of this type is in particular a mixture of sterol esters, such as the cholesterol and lanosterol ester mixture available from the manufacturer CRODA under the trade name Super Sterol Ester®,

[0089] - lanolin and its derivatives,

[0090] - mixtures of beeswax and octyldodecanol such as that marketed under the name Zenibee Cream by the company Zenitech, - the esters, - vegetable butters such as mango butter, shea butter, cocoa butter, cottonseed butter, avocado butter, or one of their mixtures.

[0091] Among the esters, the following may be used in particular: - esters of an oligomeric glycerol, in particular diglycerol esters, especially adipic acid and glycerol condensates, in which part of the hydroxyl groups of the glycerols have reacted with a mixture of fatty acids such as stearic acid, capric acid, stearic acid and isostearic acid and 12-hydroxystearic acid, in particular those marketed under the Softisan 649 brand by the company Sasol, - arachidyl propionate marketed under the brand name Waxenol 801 by Alzo, - phytosterol esters such as the product with the INCI name "bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate" marketed under the name Plandool-G by Nippon Fine Chemical Co, and "Phytosteryl / behenyl / octyldodecyl / isostearyl lauroyl glutamate" marketed under the name Eldew-PS308 by Ajinomoto, - fatty acid triglycerides and their derivatives, for example the mixture of stearyl heptanoate and stearyl caprylate marketed under the name DUB solid by the company Stéarinerie Dubois, - pentaerythritol esters, - non-crosslinked polyesters resulting from polycondensation between a C4-C50 linear or branched dicarboxylic acid or polycarboxylic acid and a C2-C50 diol or polyol, - aliphatic esters of ester resulting from the esterification of an aliphatic hydroxycarboxylic acid ester by an aliphatic carboxylic acid such as cetyl lactate marketed under the name ceraphyl 28 by the company ISP (International Speciality Products), - polyesters resulting from the esterification, by a polycarboxylic acid, of an aliphatic hydroxycarboxylic acid ester, said ester comprising at least two hydroxyl groups such as the products Risocast DA-H ®, and Risocast DA-L ®, or one of their mixtures.

[0092] Among the additional pasty fats, preference will be given to phytosterol esters such as the product with the INCI name "bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate" marketed under the name Plandool-G by Nippon Fine Chemical Co, "Phytosteryl / behenyl / octyldodecyl / isostearyl lauroyl glutamate" marketed under the name Eldew-PS308 by Ajinomoto, or a mixture of these.

[0093] The compositions may include additional fats having a melting point between 25°C and 55°C. The fat having a melting point between 25°C and 55°C is selected from hydrogenated oils solid at 25°C or fatty esters solid at 25°C and mixtures thereof.

[0094] Among the solid hydrogenated oils at 25°C, we can mention hydrogenated castor oil, hydrogenated palm oil, hydrogenated tallow, hydrogenated coconut oil such as for example that available under the trade name hydrobase 32-34 by the company Prod'Hyg.

[0095] Among the solid fatty esters at 25°C, we can mention propylene glycol myristate, myristyle myristate and cetyl alcohol.

[0096] The fatty constituent having a melting point between 25°C and 55°C is preferably hydrogenated coconut oil.

[0097] According to embodiments, the cosmetic compositions according to the invention comprise less than 3% by weight of pasty fats of mineral and / or synthetic origin, in particular less than 1% by weight, the percentages being expressed by weight relative to the total weight of the composition.

[0098] Preferably, cosmetic compositions are free from pasty fats of mineral and / or synthetic origin.

[0099] Among the pasty fats of mineral and / or synthetic origin, we can mention vaselines, also called petrolatum.

[0100] - vinyl polymers, in particular olefin homopolymers and copolymers, homopolymers and copolymers of hydrogenated dienes, linear or branched oligomers, homo or copolymers of alkyl (meth)acrylates preferably having an alkyl group at C8-C30, homo and copolymer oligomers of vinyl esters having alkyl groups at C8-C30, homo and copolymer oligomers of vinyl ethers having alkyl groups at C8-C30, - liposoluble polyethers resulting from the polyetherification between one or more diols at C2-C100, preferably at C2-C50, According to embodiments, the solid cosmetic compositions according to the invention comprise less than 3% by weight of silicone and / or fluorinated pasty fats, in particular less than 1% by weight, the percentages being expressed by weight relative to the total weight of the composition.

[0101] Preferably, cosmetic compositions are free from silicone and / or fluorinated pasty fats. POLAR NON-VOLATILE OIL

[0102] For the purposes of the present invention, "oil" means a compound which has a lipophilic character and which, when introduced at a rate of at least 1% by weight into water at 20°C, is not at all soluble in water, or soluble to a rate of less than 10% by weight, relative to the weight of oil introduced into the water.

[0103] For the purposes of the present invention, a polar non-volatile oil may be natural or derived from nature.

[0104] The term "non-volatile oil" means an oil which has a boiling point generally above 300°C under 760 mm Hg (101325 Pa) and which has little or no vapor pressure.

[0105] The composition according to the invention may comprise one or more non-volatile oils miscible with each other.

[0106] The definition of the solubility parameters in the three-dimensional HANSEN solubility space is described in the article by CM HANSEN: “The three dimensional solubility parameters” J. Paint Technol. 39, 105 (1967).

[0107] According to this Hansen space: - ôD characterizes the London dispersion forces arising from the formation of induced dipoles during molecular collisions; - ôP characterizes the DEBYE interaction forces between permanent dipoles as well as the KEESOM interaction forces between induced dipoles and permanent dipoles; - ôh characterizes specific interaction forces (such as hydrogen bonds, acid / base, donor / acceptor, etc.)

[0108] These three parameters can be treated as the coordinates of a point in three dimensions in Hansen space. The closer the solvents are in this three-dimensional space, the more likely they are to dissolve in one another. They are based on the affinity of the molecules for each other, "like dissolves like".

[0109] The parameters ôD, ôP, ôh are expressed in (MPa)l / 2, unit equivalent to (J / cm3)l / 2.

[0110] The Hansen solubility parameters are calculated using HSPiP software version V5.3.06 from a chemical structure; the method selected in the software is Y-MB or Yamamoto-Molecular Break.

[0111] This software is available for download from the official Hansen parameters and HSPiP software website at www.hansen-solubility.com.

[0112] The Log Kow or LogP, is a measure of the differential solubility of molecules in water and in octanol; P is the octanol / water partition coefficient.

[0113] LogP = Log(Coct / Ceau).

[0114] This value allows us to understand the hydrophilic or lipophilic nature of the molecule.

[0115] If the LogP is positive and very high, the molecule in question is much more soluble in octanol than in water, reflecting its lipophilic character; conversely, if the LogP is negative, this means that the molecule in question is hydrophilic. A LogP of zero means that the molecule is soluble in both solvents.

[0116] Preferably, the oils used according to the present invention have a LogP greater than 0.

[0117] For the purposes of this invention, "polar oil" means an oil whose chemical structure is essentially formed, or even made up, of carbon and hydrogen atoms, and comprising at least one strongly electronegative heteroatom such as an oxygen, nitrogen, silicon or phosphorus atom.

[0160] The term “lipophilic gelling agent”, in the context of this application, refers to a substance capable of solidifying or gelatinizing the oil present in the composition of the invention.

[0161] Among the lipophilic gelling agents used, we can mention in particular organic or mineral polymeric or molecular lipophilic gelling agents.

[0162] Another type of organic polymeric lipophilic gelling agent other than sucrose polyester consists of dextrin esters. Examples include dextrin and fatty acid esters, such as dextrin palmitate.

[0163] Another type of organic polymeric lipophilic gelling agent consists of glyceryl esters. One example is the diester of eicosadiotic acid and glycerol esterified with behenic acid. It is notably available under the trade name NOMCORT® HK-G from NISSHIN OILLIO.

[0164] As a lipophilic mineral gelling agent, one can cite fumed silica, possibly with a hydrophobic surface treatment, whose particle size is less than 1 pm. It is indeed possible to chemically modify the surface of silica by a chemical reaction that reduces the number of silanol groups present on the silica surface. In particular, silanol groups can be substituted by hydrophobic groups, resulting in hydrophobic silica. The hydrophobic groups can be: - trimethylsiloxyl groups, which are notably obtained by treating fumed silica in the presence of hexamethyldisilazane. Silicas treated in this way are designated "Silica silylate" according to the CTFA (8th edition, 2000).For example, they are marketed under the references Aerosil R812® by DEGUSSA, and CAB-O-SIL TS-530® by CABOT. These are dimethylsilyloxyl or polydimethylsiloxane groups, obtained in particular by treating fumed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. Silicas treated in this way are called "Silica dimethyl silylate" according to the CTFA (8th edition, 2000). For example, they are marketed under the references Aerosil R972® and Aerosil R974® by DEGUSSA, and CAB-O-SIL TS-610® and CAB-O-SIL TS-720® by CABOT.

[0165] Hydrophobic pyrogenated silica has in particular a particle size that can be nanometric to micrometric, for example ranging from about 5 to 200 nm.

[0169] Examples of poly(ester-amides) terminated by an ester (ETPEA) are those identified by the INCI name polyamide-8 which are "Ethylenediamine bis-stearyl dibenzoate dimer copolymers ethylenediamine / neopentyl glycol / stearyl" and available, for example, under the trade name Oloecraft® LP-20-PA-MV from the Croda company.

Examples include an N-acylglutamic acid diamide with a straight-chain alkyl group, such as dibutyl lauroyl glutamide, and an N-acylglutamic acid diamide with a branched-chain alkyl group, such as dibutyl ethylhexanoyl glutamide. Dibutyl lauroyl glutamide is commercially available as GP-1 and dibutyl ethylhexanoyl glutamide is commercially available as EB-21, both marketed by Ajinomoto.

[0174] Among lipophilic gelling agents, sucrose and fatty acid esters, dextrin esters and glyceryl esters are preferred. FILMOGEN

[0175] The composition according to the invention may also include at least one film-forming polymer.

[0176] Among the film-forming polymers that can be used in the compositions of the present invention, we can mention synthetic polymers, of radical type or of polycondensate type, polymers of natural origin, and their mixtures.

[0178] Radical-type film-forming polymers may include vinyl polymers or copolymers, in particular acrylic polymers.

[0179] Vinyl film-forming polymers can result from the polymerization of ethylenically unsaturated monomers having at least one acid group and / or esters of these acid monomers and / or amides of these acid monomers.

[0185] Particularly preferred esters of (meth)acrylic acid are alkyl (meth)acrylates.

[0186] According to the present invention, the alkyl group of the esters can be either fluorinated or perfluorinated, that is to say that part or all of the hydrogen atoms of the alkyl group are substituted by fluorine atoms.

[0187] Examples of amides of acid monomers include (meth)acrylamides, and in particular N-alkyl (meth)acrylamides, especially alkyl in C2-C12. Among the N-alkyl (meth)acrylamides, examples include N-ethyl acrylamide, Nt-butyl acrylamide, Nt-octyl acrylamide and N-undecylacrylamide.

[0188] Vinyl film-forming polymers can also result from the homopolymerization or copolymerization of monomers selected from vinyl esters and styrenic monomers.

[0203] According to one embodiment, the film-forming polymer can be a polymer solubilized in a liquid fatty phase comprising organic oils or solvents (the film-forming polymer is then said to be a liposoluble polymer).

[0204] As an example of a liposoluble polymer, one may cite copolymers of vinyl ester (the vinyl group being directly linked to the oxygen atom of the ester group and the vinyl ester having a saturated hydrocarbon radical, linear or branched, of 1 to 19 carbon atoms, linked to the carbonyl of the ester group) and at least one other monomer which may be a vinyl ester (different from the vinyl ester already present), an α-olefin (having from 8 to 28 carbon atoms), an alkyl vinyl ether (whose alkyl group comprises from 2 to 18 carbon atoms), or an allylic or methallylic ester (having a saturated hydrocarbon radical, linear or branched, of 1 to 19 carbon atoms, linked to the carbonyl of the ester group).

EXAMPLES

[0242] Protocol

[0243] The lipstick formulations in Table 2 were prepared as follows: The polar non-volatile oils are dispersed under stirring (150 rpm) in a beaker in a water bath at 95°C. When present, the functionalized castor oil, used as the sole lipophilic gelling agent, is dispersed in the polar oils at 95°C for 30 minutes until completely dispersed. Then, maintaining the temperature at 95°C and stirring, the waxes are added and allowed to disperse until a completely homogeneous mixture is obtained; then the film-forming agents and finally the pastes are added. This yields the completely molten white body in the form of a homogeneous and clear mixture into which the pigments, previously ground in polyglyceryl 3 diisostearate (Cithrol PG32IS marketed by Croda), are incorporated. The following is then added: Now, set the temperature to 95°C and agitate (150 rpm). Add the fillers, mother-of-pearl, active ingredients, fragrance, and antioxidants (if present). Pour into molds at 85°C.

[0244] Place the molds at -20°C for 10 minutes then unmold.

[0248]

[0249] The lipstick formulations were subjected to breakage tests on lips. The results of these tests are excellent, as none of the 20 lipsticks in Example 1 of the invention formulated with functionalized castor oil broke. The 20 lipsticks in comparative example 1, in which functionalized castor oil was replaced by polar non-volatile oil (caprylic / capric triglyceride), the formula being otherwise identical to that of example 1, were all broken during the test. None of the 20 lipsticks in comparative example 2, in which functionalized castor oil was replaced by ABWAX REVOWAX wax, the formula otherwise being identical to that of example 1, were broken. Exudation tests were also carried out. Exudation is a seepage phenomenon resulting in the appearance of oily deposits rising to the surface of the anhydrous product in the form of micro-pitting, droplets, or patches oily. For this test, 12 lipsticks are positioned at different temperatures (27°C, 30°C, 35°C and 45°C) and are examined after 1h, 4h and 24h of waiting to see if any oozing is visible.

[0250] No exudation phenomenon was observed with the lipsticks of example 1 of the invention formulated with functionalized castor oil, just like those formulated with comparative example 2 in which the functionalized castor oil was replaced by ABWAX REVOWAX wax.

[0251] In contrast, an exudation phenomenon was observed with the lipsticks in comparative example 1, in which the functionalized castor oil was replaced by the polar non-volatile oil (caprylic / capric triglyceride). Indeed, droplets of oil appeared on the surface of the stick and did not disappear after returning to room temperature, indicating the instability of these sticks.

[0252] Sensory tests were carried out on 25 trained volunteers to evaluate the glide. The results of these tests are excellent, as the lipsticks of Example 1 of the invention, formulated with functionalized castor oil, exhibit very good glide upon application.

[0253] The lipsticks of comparative example 1 in which functionalized castor oil has been replaced by polar non-volatile oil (caprylic / capric triglyceride) exhibit a glide similar to that felt for the lipsticks of example 1 of the invention.

[0254] On the other hand, the lipsticks in comparative example 2, in which functionalized castor oil has been replaced by ABWAX REVOWAX wax, exhibit a significantly reduced glide.

[0255] Stability tests were performed on the lipsticks. Different lipstick sticks were incubated at different temperatures (4°C, 20°C, 40°C, and 45°C). The lipsticks were then observed on days 1, 15, 30, and 60. The lipsticks of Example 1 of the invention, formulated with functionalized castor oil, retained their good hold, smoothing effect, and shine throughout the incubation period.

[0256] The results of butter-cutting wire measurements are presented in Table 3. Example 1 of an invention Comparative example 1 Comparative example 2 Measurement test wire for butter (g) 192 g 162 g 232 g

[0257] [Table 3]

[0258] Hardness is measured at 20°C using the so-called "butter wire" method, which consists of assessing the firmness of a lipstick by measuring, in particular, its resistance The product's resistance is measured when cut into sticks. This measurement is taken 24 hours after formulation, using a texture analyzer (TAXTPlus, MicroStable Systems, UK) equipped with a 5 kg load cell and its Butter Cutter A / BC probe (Swantech, MicroStable Systems, UK). It measures the maximum resistance force of the stick when the butter-cutting wire penetrates to a depth of 9 mm at a speed of 1.6 mm / s. To ensure reproducibility, the analysis is repeated on 6 sticks, and the relative difference between measurements should not exceed 10%, ideally 5%.

[0259] The solid composition according to the invention has adequate stability and hardness: the stick is sufficiently rigid and solid, does not break during application and is thus compatible with packaging in stick form or in another solid form and with application by friction on the surface to be treated and / or made up; it is also characterized by ease of application such as good glide, good deposit from the first application and a comfortable texture.
