Description

Title of the invention: LIQUID COSMETIC COMPOSITION COMPRISING SILICONE OILS AND HYDROCARBON-BASED OILS, AND THEIR PROCESSES. FIELD OF THE INVENTION

[0001] This disclosure relates, in general, to the field of cosmetic and personal care products and, in particular, to liquid cosmetic compositions for applying makeup to the skin or lips. This disclosure further relates to a method of applying makeup to the skin or lips. CONTEXT OF THE INVENTION

[0002] Among the various cosmetic products, lipsticks are one of the most popular makeup items, perceived as providing the user with increased confidence and enhanced appearance. The formulations can be in various forms, from liquid to solid, such as sticks or those poured into pots. Traditional liquid lipsticks often require several applications throughout the day to compensate for their relatively short staying power. In addition to not being long-lasting, they also tend to transfer color, with the risk of leaving marks on glasses, cups, or even clothing. Therefore, some users prefer long-lasting lipsticks, which eliminate the need for frequent touch-ups.This type of lipstick, particularly liquid formulas, typically contains film-forming polymers and a significant amount of volatile oils, which ensure the film's durability on the lips. However, such long-lasting formulas have the drawback of being sticky and / or leaving a feeling of dryness or tightness on the lips. Consequently, such liquid formulas can be considered less comfortable than others. Some liquid lipsticks on the market use non-volatile oils and emollients to counteract the tightness and dryness and to further moisturize the lips. However, in many cases, the buildup of the cosmetic formula leaves a heavier, or even, in some cases, a cardboard-like feeling on the lips, and the film's durability can often be compromised.Thus, lipstick users are constantly searching for products that offer better makeup effects on the lips, combined with long-lasting and comfortable application.

[0003] Therefore, there is a need for an effective and stable liquid cosmetic composition with improved properties, in particular a composition that is long-lasting and comfortable to wear. Summary of the invention

[0004] One aspect of this disclosure proposes a liquid cosmetic composition for skin or lip makeup, the composition comprising: (a) a non-volatile, non-polar hydrocarbon-based oil in an amount of 15% to 25% by weight relative to the total weight of the composition; (b) a volatile, non-polar hydrocarbon-based oil in an amount of 30% to 50% by weight relative to the total weight of the composition; (c) a mixture of at least one volatile silicone oil and at least one non-volatile silicone oil, in which the volatile silicone oil is in an amount of 2% to 10% by weight relative to the total weight of the composition; and the non-volatile silicone oil is in an amount of 2% to 5% by weight relative to the total weight of the composition; (d) a trimethylsiloxysilicate; and (e) a lipophilic gelling agent.

[0005] Another aspect of this disclosure proposes a kit comprising (a) the composition as described herein; (b) a container; and (c) an applicator.

[0006] Another aspect of the present disclosure proposes a method for applying makeup to the skin or lips, comprising applying to said skin or lips the composition as described herein.

These definitions should be read in light of the rest of the disclosure and understood as by a person skilled in the art. The terms used herein have meanings recognized and known to persons skilled in the art; however, for For reasons of convenience and completeness, specific terms and their meanings are set out below.

[0011] The terms "include" and "comprising" are used in an inclusive and open sense, meaning that additional elements (or steps) may be included. They are not intended to be interpreted as "consisting solely of" or as excluding other elements or steps.

[0012] The term "including" is used to mean "including, but not limited to". "Including" and "including, but not limited to" are used interchangeably.

[0013] The term “INCI” is an abbreviation for International Nomenclature of Cosmetic Ingredients, which is a system of names provided by the International Nomenclature Committee of the Personal Care Products Council to identify ingredients of cosmetic or personal care products.

[0014] The term “long-lasting,” as used herein, refers to its generally accepted meaning in the art. Generally, it designates the property of a composition indicating that the composition is retained on a surface, such as the lips or skin, after application, and that the color of the composition remains the same or substantially the same as at the time of application, for a prolonged period of time. Long-lasting properties can be evaluated by any method known in the art for evaluating such properties. For example, the long-lasting property can be evaluated by a test involving the application of a composition to the skin or lips and evaluating the color and retention of the composition after a specified or prolonged period.For example, the color of a composition can be evaluated immediately after application to the skin or lips, and these characteristics can then be re-evaluated and compared after a predetermined or extended period. For lip compositions, "long-lasting" typically means that the composition remains on the lips for at least 4 hours to approximately 24 hours.

[0015] The term "anhydrous", as used here, refers to a composition comprising less than 5% by weight of water, or even less than 2% by weight of water, or even less than 1% by weight of water relative to the total weight of the composition, or even being free of water.

[0047] Trimethylsiloxysilicate

[0048] The composition, according to embodiments herein, comprises an MQ type silicone resin, in particular trimethylsiloxysilicate.

[0049] More generally, the term "resin" refers to a compound with a three-dimensional structure. "Silicone resins" are also called "siloxane resins." Thus, for the purposes of this disclosure, polydimethylsiloxane is not a silicone resin.

[0050] The nomenclature of silicone resins is known as "MDTQ", the resin being described according to the various siloxane monomer motifs it comprises, each of the letters "MDTQ" characterizing a type of motif.

[0051] The letter “M” represents the monofunctional motif of formula RlR2R3SiOi / 2, the silicon atom being bonded to a single oxygen atom in the polymer comprising this motif.

[0052] The letter “D” designates a difunctional RlR2SiO2 / 2 motif in which the silicon atom is bonded to two oxygen atoms.

[0053] The letter “T” represents a trifunctional motif of formula RlSiO3 / 2.

[0054] These resins are described, for example, in Encyclopedia of Polymer Science and Engineering, vol. 15, John Wiley and Sons, New York, (1989), pp. 265-270, and US 2 676 182, US 3 627 851, US 3 772 247, US 5 248 739 or US 5 082 706, US 5 319 040, US 5 302 685 and US 4 935 484.

[0055] In the motifs M, D and T defined above, R, namely RI and R2, represents a hydrocarbon-based radical (in particular alkyl) containing from 1 to 10 carbon atoms, a phenyl group, a phenylalkyl group or a hydroxyl group.

[0056] Finally, the letter “Q” designates a tetrafunctional SiO4 / 2 motif in which the silicon atom is bonded to four oxygen atoms, which are themselves bonded to the rest of the polymer.

[0057] Various silicone resins with different properties can be obtained from these different motifs, the properties of these polymers varying according to the type of monomers (or motifs), the nature and number of the R radical, the length of the polymer chain, the degree of branching and the size of the side chains.

[0058] Examples of MQ type silicone resins include alkyl siloxysilicates of formula [(Rl)3SiOi / 2]x(SiO4 / 2)y(MQ motifs) in which x and y are integers from 50 to 80, and such that the RI group represents a radical as defined above, and is preferably an alkyl group containing from 1 to 8 carbon atoms or a hydroxyl group, more preferably a methyl group.

[0059] Silicone resin can be used in powder form or dissolved in a solvent. Examples of solid silicone resins of type MQ are of type trimethylsiloxysilicate include those sold under the reference BELSIL® TMS 803, by Wacker, SR 1000 by Momentive Performance Materials, and Silsoft™ 74 FLUID by Momentive Performance Materials.Examples of silicone resins carried in a solvent can be cited as Koboguard® MQ65TMF (mixture of trimethylsiloxysilicate and methyl trimethicone) sold by Kobo; KF-7312J (mixture in cyclopentasiloxane), KF-7312K, KF-7312L (mixture in dimethicone), KF-7312T (mixture in trimethicone), X-21-5249 (mixture in cyclopentasiloxane), X-21-5249L (mixture in dimethicone), X-21-5250, X-21-5250L (mixture in cyclopentasiloxane and dimethicone, respectively), X-21-5595, X-21-5616 (mixtures in isododecane), KF-9021, KF-9021L (mixtures in cyclopentasiloxane and dimethicone, respectively), sold by Shin-Etsu; Silsoft 74, Silshine 151 (mixtures in isododecane) from Momentive Performance Materials; Xiameter RSN-0749v Resin, Dow Corning 749 Fluid (mixtures in cyclopentasiloxane), Dow Corning 593 Fluid (mixture in dimethicone) from Dow Corning.

The lipophilic gelling agent may in particular be chosen from silica, such as hydrophobic treated pyrogenic silica and hydrophobic silica aerogel; from clays, such as hydrophobic hectorites and hydrophobic bentonites; or mixtures thereof.

[0064] In one embodiment, the lipophilic gelling agent comprises at least one of the following: silica selected from pyrogenic silica and silica aerogel, or mixtures thereof; clays selected from hydrophobic hectorites and hydrophobic bentonites, or mixtures thereof. In one embodiment, the lipophilic gelling agent comprises at least one of the following: silica selected from pyrogenic silica, including hydrophobic treated pyrogenic silica, and silica aerogel, including hydrophobic silica aerogel, or mixtures thereof; and clays selected from hydrophobic hectorites and hydrophobic bentonites, or mixtures thereof.In another embodiment, the lipophilic gelling agent comprises at least one of the following: treated hydrophobic pyrogenic silica, hydrophobic silica aerogel, hydrophobic hectorites, hydrophobic bentonites or mixtures thereof, wherein the lipophilic gelling agent is preferably in a range of 0.5% to 16% by weight relative to the total weight of the composition.

[0065] Pyrogenic silica

[0066] The silica, according to embodiments herein, can be selected from pyrogenic silica and / or silica aerogel. Suitable pyrogenic silica includes silica having a treated hydrophobic surface. It is in fact possible to chemically modify the surface of the silica by a chemical reaction generating a reduced number of silanol groups present on the silica surface. In particular, it is possible to substitute silanol groups with hydrophobic groups, and a hydrophobic silica is then obtained.

[0067] Hydrophobic groups can be: • trimethylsiloxyl groups, which are obtained in particular by treating sublimed silica in the presence of hexamethyldisilazane. The silicas thus treated are called "Silica silylate" according to the CTFA (8th edition, 2000). • dimethylsilyloxyl or polydimethylsiloxane groups, which are obtained in particular by treating sublimed silica in the presence of polydimethylsiloxane or dimethyldichlorosilane. The silicas thus treated are called "Silica dimethyl silylate" according to the CTFA (8th edition, 2000).

[0068] Accordingly, in one embodiment, the composition comprises hydrophobically treated pyrogenic silica.

[0069] Silica aerogels

[0070] Silica aerogels, according to embodiments described herein, are porous materials obtained by replacing (by drying) the liquid component of a silica gel with air. They are generally synthesized via a sol-gel process in a liquid medium and then usually dried by extraction from a supercritical fluid, most commonly supercritical CO2. This type of drying avoids the contraction of the pores and the material. The sol-gel process and the various drying methods are described in detail in Brinker, CJ, and Scherer, GW, Sol-Gel Science: New York: Academie Press, 1990.

[0071] In one embodiment, the composition comprises a hydrophobic silica aerogel. The hydrophobic silica aerogel particles usually have a specific surface area per unit mass (SM) of 500 to 1500 m2 / g, preferably 600 to 1200 m2 / g and even better 600 to 800 m2 / g, and a size expressed as volume mean diameter (D[0,5]), of 1 to 1500 pm, in particular 1 to 1000 pm, preferably 1 to 100 pm.

[0072] In one embodiment, the hydrophobic silica aerogel particles have a size expressed as volume-average diameter (D[0.5]) ranging from 1 to 30 pm, preferably from 5 to 25 pm. In a preferred embodiment, the particles hydrophobic silica aerogels have a size expressed in volume mean diameter (D[0,5]) ranging from 5 to 20 pm and more preferentially from 5 to 15 pm.

[0073] The specific surface area per unit mass can be determined using the nitrogen absorption method called BET (BRUNAUER-EMMET-TELLER) described in "The Journal of the American Chemical Society", vol. 60, page 309, February 1938, corresponding to the international standard ISO 5794 / 1 (Annex D). The BET specific surface area corresponds to the total specific surface area of ​​the particles considered.

[0074] The particle size of silica aerogel can be measured by static light scattering using a commercially available particle size analyzer such as the Malvern MasterSizer 2000. The data are processed based on Mie scattering theory. This theory, which is accurate for isotropic particles, allows for the determination of an "effective" particle diameter in the case of non-spherical particles. This theory is described in particular in the publication by Van de Hulst, H.C., "Scattering by Small P Articles," chapters 9 and 10, Wiley, New York, 1957.

[0075] In some embodiments, the hydrophobic silica aerogel particles can have a specific surface area per unit mass (SM) ranging from 600 to 800 m2 / g and a size expressed in volume mean diameter (D[0,5]) ranging from 5 to 20 pm and more preferably from 5 to 15 pm.

[0076] The expression "hydrophobic silica", as used here, refers to any silica whose surface is treated with silylation agents, for example, with halogenated silanes, such as alkylchlorosilanes, siloxanes, in particular dimethylsiloxanes, such as hexamethyldisiloxane, or silazanes, so as to functionalize the OH groups with Si-Rn silyl groups, for example, trimethylsilyl groups.

[0077] With regard to the preparation of surface-modified hydrophobic silica aerogel particles by silylation, reference may be made to US Patent No. 7,470,725. Preferably, surface-modified hydrophobic silica aerogel particles with trimethylsilyl groups may be used.

[0078] Hydrophobic silica aerogels, according to embodiments herein, include for example the aerogel marketed under the name VM-2260 (INCI name Silica silylate), by the company Dow Corning, whose particles have an average size of about 1000 microns and a specific surface area per unit mass ranging from 600 to 800 m2 / g.

[0079] The aerogel marketed under the name VM-2270 (INCI name Silica silylate), by the company Dow Corning, is preferably used in various embodiments here, the particles of which have an average size ranging from 5-15 microns and a specific surface area per unit mass ranging from 600 to 800 m 2 / g.

[0080] The lipophilic gelling agent, according to the present embodiments, is selected from hydrophobic treated pyrogenic silica, hydrophobic silica aerogel, or mixtures thereof, preferably in a range of 0.5% to 8% by weight, more preferably in a range of 0.5% to 2% by weight relative to the total weight of the composition. In one embodiment, the composition comprises the lipophilic gelling agent, preferably in an amount of 1% to 1.8% by weight relative to the total weight of the composition.

[0081] Clays

[0109] Waxes

[0110] For the purposes of this invention, "wax" means a lipophilic compound which is solid at room temperature, having a melting point greater than or equal to 40 °C, and less than or equal to 120 °C, more particularly less than or equal to 90 °C.

[0111] For the purposes of the invention, the melting temperature (or melting point) corresponds to the temperature of the most endothermic peak observed in thermal analysis (DSC) as described in ISO 11357-3; 1999.

[0112] The melting point of a solid fatty compound can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name "DSC 2000" by TA Instruments with the "TA Universal Analysis" software.

[0113] The measurement protocol is as follows:

[0114] A 5 mg sample of wax is placed in a crucible and subjected to an initial temperature rise from -20 °C to 120 °C at a heating rate of 10 °C / minute, then cooled from 120 °C to -20 °C at a cooling rate of 10 °C / minute, and finally subjected to a second temperature rise from -20 °C to 120 °C at a heating rate of 5 °C / minute. During the second temperature rise, the melting point of the solid fat is measured, which corresponds to the temperature of the most endothermic peak of the observed melting curve.

[0115] More particularly, the wax can be chosen from polar waxes, in particular alcohol waxes; esters such as waxes of animal or vegetable origin, such as beeswax, lanolin, sunflower, candelilla, carnauba, rice bran, lignite, hydrogenated jojoba oil; waxes resulting from the hydrogenation of esters obtained from C6-C22 fatty alcohols of vegetable origin and vegetable oil; waxes of formula R1COOR2 in which RI and R2 represent linear, branched or cyclic aliphatic chains whose number of atoms varies from 10 to 50, which may contain a heteroatom, in particular oxygen, and whose melting temperature varies from 40 to 120 °C; partial or total agents, preferably total, of a C16-C30 saturated carboxylic acid with glycerol, such as glyceryl tristearate or glyceryl tribehenate, glyceryl trihydroxystearate, and mixtures thereof.

[0116] We can also mention non-polar hydrocarbon waxes (i.e. made up solely of carbon and hydrogen atoms), resulting from the transformation of petroleum, such as, for example, polyethylene waxes, polymethylene waxes (synthetic wax, Fischer-Tropsch), alone or in mixtures.

[0117] Pasty compounds

[0118] For the purposes of this invention, "pasty compound" means a lipophilic compound comprising, at room temperature, a liquid fraction and a solid fraction. Thus, a pasty compound may have an initial melting point below 25 °C.

[0119] The melting point of the paste-like compound is determined according to the same principle as that detailed above for waxes. However, in the case of a paste-like compound, the measurement protocol is as follows:

[0120] A 5 mg sample of a paste-like compound placed in a crucible is subjected to a first temperature increase from -20 °C to 100 °C at a heating rate of 10 °C / minute, then cooled from 100 °C to -20 °C at a cooling rate of 10 °C / minute, and finally subjected to a second temperature increase from -20 °C to 100 °C at a heating rate of 5 °C / minute. The melting point of the paste-like compound is the temperature value corresponding to the peak of the curve representing the variation of the difference in absorbed power as a function of temperature.

[0121] It should be noted that the liquid fraction by weight of the paste-like compound at room temperature is equal to the ratio between the enthalpy of fusion consumed at room temperature and the enthalpy of fusion of the paste-like fat. The enthalpy of fusion of the paste-like compound is the enthalpy consumed by the latter to change from the solid to the liquid state. The paste-like compound is said to be in the solid state when all of its mass is in crystalline solid form. The paste-like compound is said to be in the liquid state when Its entire mass is in liquid form. The enthalpy of fusion of the paste-like compound is the amount of energy required to change the paste-like compound from a solid to a liquid state. It is expressed in J / g. The enthalpy of fusion of the pasty fat substance is equal to the area under the curve of the resulting thermogram.

[0122] Preferably, the paste-like compounds, also called hydrocarbon-based paste-like compounds, are selected from petroleum jelly; vegetable butters, such as in particular mango, shea, cupuacu, murumuru, cocoa, babassu or jojoba butters; fully or partially hydrogenated vegetable oils, such as, for example, hydrogenated soybean oil, hydrogenated coconut oil, hydrogenated rapeseed oil, mixtures of hydrogenated vegetable oils such as products bearing the INCI name hydrogenated vegetable oil, partially hydrogenated olive oil; hydrogenated castor oil esters and Cl6-C22 fatty acids, bis-diglyceryl-2 polyacyladipate; products bearing the INCI name hydrogenated coco-glycerides;dilinoleic alcohol and / or dilinoleic acid dimer esters, for example products bearing the following INCI names: bis-behenyl / isostearyl / phytosteryl dimer dilinoleyl dimer dilinoleate, phytosteryl / isostearyl / cetyl / stearyl / behenyl dimer dilinoleate), hydrogenated castor oil dimer dilinoleate, or mixtures thereof.

[0123] According to a preferred embodiment of the present invention, the amount of solid fatty compound, if present in the composition, is at most 2% by weight, more particularly at most 1% by weight, relative to the total weight of the composition. Preferably, the composition according to the invention does not comprise any solid fatty compound.

[0166] The viscosity of the compositions was measured using a Lamy Rheology Rheomat RM 200 type rheometer with a 3-spindle at a speed of 200 rpm, at room temperature (25 °C) and under atmospheric pressure (760 mmHg). The measurement was taken after 10 minutes of spindle rotation within the composition, at a shear rate of 200 rpm. Example 1 Examples of work

[0167] The liquid cosmetic compositions in accordance with this disclosure provided in Table 1 were prepared as described below.

[0168] Preparation of liquid cosmetic composition;

[0169] Before the preparation of the compositions, the phase A ingredients were subjected to a grinding process.

[0170] The ingredients of phase A were mixed with a portion of the phase B1 ingredient and the phase B2 ingredients by passing them three times through a triple roller mill at room temperature to obtain the first mixture. In a separate container, the ingredients of phase C were mixed with the remaining portion of the phase B1 ingredient to obtain the second mixture. The phase D ingredients and the first mixture were added sequentially to the second mixture under constant stirring. The mixture was stirred for 5 minutes to obtain a homogenized liquid cosmetic composition.

[0171] The compositions are prepared at room temperature (25 °C).

[0173] As observed in Table 1 above, all compositions were stable according to the protocols mentioned above, and proved easy to apply with good sliding properties.

[0174] The viscosities of each of these compositions were found to be between 0.6 and 1.3 Pa.s.

[0175] The composition deposits were precise and were found not to migrate into the fine lines around the lips.

[0176] The deposits were also observed to be matte, comfortable, non-sticky, non-drying to the lips, with good staying power and very little transfer. Example 2 Comparative Examples

[0177] The liquid cosmetic compositions provided in Table 2 were prepared by a process as described previously in Example 1.

[0179] Composition C (6) was not stable after 2 weeks at 50 °C and released oil. Furthermore, the deposit resulting from the composition was not long-lasting.

[0180] Composition C (7) was observed to be a thick cream. The composition was less easy to apply and was found to dry quickly. The residue left a drying sensation on the lips and was uncomfortable.

[0181] Consequently, it is observed that the comparative examples (Table 2) obtained unsatisfactory results, with stability problems that can be attributed to a discrepancy in the use of ingredients and the weight percentages of ingredients such as volatile and non-volatile silicone oils. Therefore, it is essential to maintain the ingredients, as disclosed herein, within the desired ranges to obtain a stable liquid cosmetic composition with the desired cosmetic properties.
