Abstract
Description
[Technical Field]
[0001] The present invention relates to a composition in the form of a reverse-phase (water in oil) emulsion comprising a first non-volatile oil selected from ethylcellulose and fatty alcohols, a second non-volatile hydrocarbon oil of ether or carbonate type, and at least one nonionic hydrocarbon surfactant. The present invention also relates to a method for applying and / or caring for a human keratinous substance, particularly the lips, to which the composition is applied. [Background technology]
[0002] For several years, makeup compositions containing ethylcellulose have been developed that offer a primary alternative to the presence of large amounts of ethanol, which can be used as a solvent for ethylcellulose and may cause long-term skin or lip sensitivity problems. This is because, for example, ethylcellulose is no longer soluble in ethanol but exhibits certain solubility parameters, and is particularly soluble in fatty alcohols, natural oils, and C6-C6 alcohols. 30 One of the desired objectives of (Patent Document 1) was to describe anhydrous compositions dissolved in a solvent selected from triglycerides or glycol esters. These compositions exhibit good adhesion and limited migration.
[0003] The compositions produced in emulsion form were subsequently described in (Patent Document 2), for example, in relation to an oil-in-water emulsion particularly comprising ethylcellulose, at least one liquid fatty alcohol, and at least one non-volatile silicone or fluorinated oil. The compositions thus obtained are easy to apply, provide a cooling effect upon application, and the resulting deposits are non-sticky, do not move significantly, and are glossy and thus persistent.
[0004] However, instead, for some time, the trend in cosmetics has been towards the development of compositions that contain more natural products and thus, in particular, fewer synthetic compounds such as silicones. Simply replacing these oils with hydrocarbon-based compounds, such as ester oils, for example, does not make it possible to achieve the desired objectives, such as its gloss and wear resistance over a long period. Specifically, silicone oils are known to be particularly effective in this regard. Furthermore, from the above-mentioned international application, it is exemplified that the replacement of silicone or fluorinated oils with triglycerides does not give a homogeneous composition. Furthermore, the resulting composition has been found to be difficult to apply, and as a result, a homogeneous makeup of the lips cannot be obtained.
[0005] Therefore, there is still a need for a composition in the form of an emulsion containing ethyl cellulose, which in particular limits the use of synthetic oils such as silicone oils and can be applied as a shiny deposit that retains its gloss even without it for a long time, especially for lip makeup. It is very clear that such a result must be achieved without harming the application properties of the composition or the application properties of the resulting deposit, such as mobility, etc.

Summary of the Invention
Means for Solving the Problems
[0007] These and other objects are achieved by the present invention, which is - ethyl cellulose; - saturated or unsaturated, straight-chain or branched C 10 ~C 26At least one first non-volatile oil selected from fatty alcohols and which is liquid at 25 °C and atmospheric pressure (1.013×10 5 Pa); and - at least one second hydrocarbon oil selected from ethers of the formula ROR', carbonates of the formula RO(CO)OR' (wherein the R and R' groups may be the same or different and are saturated or unsaturated, branched or unbranched hydrocarbon-based groups containing up to 16 carbon atoms, preferably C3 - C 16 groups) and mixtures thereof, and which is liquid at 25 °C and atmospheric pressure (1.013×10 5 Pa); and - at least one non-ionic hydrocarbon surfactant, A composition in the form of a water-in-oil emulsion containing.
[0008] The present invention also relates to a method of applying makeup and / or caring for human keratin substances, particularly the skin and lips and more particularly the lips, which consists of applying a composition as described above.
[0009] The composition according to the invention is more particularly in the form of a gel. This has the advantage of being easy to apply as a thick deposit on the lips, yet still being comfortable, not overly sticky or non-sticky, and having an associated cooling sensation. The resulting deposit is shiny and retains its shine for a long time; it provides a moisturizing effect and gives a volumizing effect (a plump appearance) to the lips. It also exhibits satisfactory non-smudging properties.
Mode for Carrying Out the Invention
[0010] Gloss Measurement Protocol To obtain a film of controlled thickness, the sample was spread over the entire contrast card (Erichsen type 24 / 5) with black and white areas using an automatic spreader (Elcometer 4340 Applicator) calibrated to a thickness of 100 μm (Elcometer 3520 / 101; 50, 100, 150, 200 μm, reference K0003520M101).
[0011] Spread the film across both the black and white areas of the contrast card. The black area of the contrast card allows for monitoring the uniformity of the spread; the white area of the contrast card is used to measure the gloss of the film.
[0012] Gloss measurements are performed using a Mini Gloss Meter 60°, BykGardner, which is calibrated to 60° before measurement.
[0013] To prevent damage to the film, two self-adhesive rings (Crowns DTM, 22mm diameter, ref. G022363M) are placed on each end of the gloss meter. Gloss is measured at various times. After application at 20°C and 50% relative humidity, gloss is measured immediately at T0, at T30min, at T1h, at T1h30, and at T24h.
[0014] Protocol for measuring the rheological properties of gels Measurements are performed using a stress-controlled rheometer (ARG2 from TA Instruments). The measurement geometry used is a smoothed (sanded) cone / plate with a diameter of 35 mm and an angle of 2°. A sinusoidal stress is applied to the sample by increasing the amplitude at a frequency of 1 Hz over a stress range of 0.1 to 1000 Pa. The resistance of the sample to the applied strain allows for the acquisition of a consistency G* curve as a function of stress τ and a solid / liquidity curve δ. The main data recovered are plateau G* (concentration) and phase angle δ (solid / liquidity).
[0015] The composition is provided more specifically in the form of a gel, and its G* coefficient (coefficient of viscoelasticity) is 10 to 1000 Pa for a phase angle of 40° to 70°, more specifically 50 to 1000 Pa for a phase angle of 40° to 65°, preferably 40° to 60°, and actually even further 80 to 1000 Pa. The viscoelastic properties (G* and δ) are measured with a stress-controlled rheometer, and the values are taken when the viscoelasticity is plateauing at 25°C.
[0016] Protocol for measuring viscosity Viscosity measurements are generally performed at 25°C using a Rheomat RM 100 viscometer equipped with a No. 4 spindle. The measurement is taken after rotating the spindle in the composition for 10 minutes at a shear rate of 200 revolutions per minute (rpm).
[0017] Generally, the compositions according to the present invention exhibit a viscosity of 5 to 50 Pa.s, preferably 7 to 30 Pa.s.
[0018] Protocol for measuring adhesive strength The composition is deposited onto several stainless steel dishes to a depth of 100 μm and leveled as quickly as possible. The dishes are dried at ambient temperature for 1 hour.
[0019] The device used is a TA.XT2i texture analyzer. A clamp mounted on this device grips a 6mm diameter AU4G cylinder, and its end is bonded to a smooth, grayish-white synthetic skin piece of the same diameter and 2mm thick.
[0020] Never perform multiple measurements at the same location on the deposit.
[0021] The parameters for the compressibility test with holdover time are as follows: approach speed (or pre-speed): 1 mm / s; speed (starting from contact detection): 0.1 mm / s; force (and corresponding pressure): 0.283 N (i.e., 0.01 MPa); waiting time: 3 s; return speed (or post-speed): 0.1 mm / s.
[0022] The adhesive force is characterized by the amount of peeling work measured during unloading (tensile phase), which corresponds to the integral of the curve under the time axis. This work is expressed as a positive value in joules / square meter.
[0023] As shown above, the compositions according to the present invention can be applied to human keratinous substances, particularly to the skin or lips. These compositions include physiologically acceptable media, i.e., media suitable for application to the skin and / or physical development on its surface, which consequently exhibit pleasant color, pleasant scent and pleasant feel, and do not cause any unacceptable discomfort (stinging, stiffness) that would cause consumers to stop using the composition.

When the three hydroxyl groups are completely substituted, the degree of substitution for each anhydroglucose unit becomes 3, or in other words, the content of alkoxy groups, particularly ethoxy groups, becomes 54.88%.
[0026] The ethylcellulose polymer used in the cosmetic composition according to the present invention preferentially has a degree of substitution of ethoxy groups in the range of 2.5 to 2.6 per unit of anhydroglucose, in other words, contains an ethoxy group content in the range of 44% to 50%.

[0093] Further nonionic surfactants may be selected from, in particular, (poly)oxyalkylened alkyl- and polyalkyl esters; (poly)oxyalkylened alcohols; (poly)oxyalkylened ethers; (poly)oxyalkylened sorbitan alkyl- and polyalkyl esters; (poly)oxyalkylened or non-(poly)oxyalkylened sorbitan ethers; alkyl- and polyalkyl glycosides or polyglycosides, in particular alkyl- and polyalkyl glucosides or polyglucosides; (poly)oxyalkylened (poly)glycerol alkyl- and polyalkyl esters; (poly)oxyalkylened or non-(poly)oxyalkylened (poly)glycerol alkyl- and polyalkyl ethers; and mixtures thereof. These compounds, more specifically, contain at least one C8-C 30It contains alkyl radicals; the oxyalkylene units are C2-C3, preferably ethylene oxide units. The number of oxyalkylene units, more specifically oxyethylene units, and also the number of (poly)glycerol units varies as a function of the desired HLB value.
[0094] If they are present, the content of additional nonionic surfactants is favorably less than the content of the first surfactant. Their content is very obviously determined in order to maintain the water-in-oil emulsion.
[0095] More specifically, if any of the compositions are included, the content of further nonionic surfactants corresponds to 0.01% to 1% by mass, preferably 0.1% to 1% by mass, based on the total mass of the compositions.
[0096] More specifically, the content of the additional nonionic surfactant corresponds to 1% to 50% by mass, more favorably 1% to 25% by mass, relative to the mass of the first surfactant.
[0097] Preferably, the composition lacks further nonionic surfactants.
[0098] Further anionic surfactants The compositions according to the present invention may optionally include at least one further anionic, more specifically hydrocarbon-based, surfactant.
[0099] Anionic surfactants include alkyl sulfates, alkyl ether sulfates, carboxylates, amino acid derivatives, sulfonates, isethionates, taurates, sulfosuccinates, alkyl sulfoacetates, phosphates and alkyl phosphates, polypeptides or C 10 ~C 30 They can be selected from metal salts of fatty acids.
[0100] More specifically, these compounds are in the form of alkali metal salts, such as sodium or potassium, or primary or secondary, especially C2-C4, such as amines or alkanolamines.
[0101] These compounds generally contain 10 to 30 carbon atoms, particularly 10 to 20 carbon atoms, in their longest hydrocarbon chains, and are saturated or unsaturated and linear, branched or cyclic. They may further contain up to 20 oxyalkylene units, preferably up to 15 units (particularly oxyethylene units).
[0102] If the composition contains any of the anionic surfactants, the content of any further anionic surfactants is such that the composition is in the form of a water-in-oil emulsion.
[0103] More specifically, if any of the compositions are included, the content of further anionic surfactants is 1% by mass or less, more specifically 0.4% by mass or less, and more specifically 0.3% by mass or less, relative to the mass of the composition. For example, the content of further anionic surfactants may be 0.01% to 1% by mass, relative to the total mass of the composition.
[0104] More specifically, the content of the anionic surfactant corresponds to 1% to 50% by mass, more favorably 1% to 25% by mass, relative to the mass of the first surfactant.
[0105] Preferably, the composition lacks further anionic surfactants.
[0106] coloring agent According to a specific embodiment of the present invention, the composition according to the present invention comprises at least one colorant that is synthetic, natural, or of natural origin.
[0107] The colorants may be selected from coated or uncoated pigments, water-soluble dyes, and lipid-soluble dyes.
[0108] pigment The term "pigment" is understood to mean white or colored and inorganic or organic particles that are insoluble in the medium in which they are found and are intended to color and / or opaque the resulting composition and / or deposits.
[0109] Inorganic pigments and pearlescent luster agents According to certain embodiments, the pigments used in the present invention are selected from inorganic pigments.
[0110] The term "inorganic pigment" means any pigment that satisfies the definition in the chapter on inorganic pigments in Ullmann's Encyclopaedia. Among the inorganic pigments used in this invention, examples include zirconium oxide or cerium oxide and also zinc oxide, iron oxide (black, yellow, or red) or chromium oxide, manganese violet, ultramarine blue, chromium hydrate and ferric blue, titanium dioxide or metal powders, such as aluminum powder and copper powder. The following inorganic pigments may also be used: Ta2O5, Ti3O5, Ti2O3, TiO, ZrO2 as a mixture with TiO2, ZrO2, Nb2O5, CeO2, ZnS.
[0111] The diameter of the pigment is generally greater than 100 nm, and may be in the range of 10 μm at most, preferably 200 nm to 5 μm, and more preferably 300 nm to 1 μm.
[0112] According to a particular embodiment of the present invention, the diameter of the pigment is characterized in that D
[50] is greater than 100 nm and can be as close to 10 μm as possible, preferably 200 nm to 5 μm, and more preferably 300 nm to 1 μm.
[0113] This diameter is measured by static light scattering using a commercially available particle size analyzer of the Master Sizer 3000® type from Malvern, which allows for the determination of the particle size distribution of all particles over a wide range, from 0.01 μm to 1000 μm. The data is processed based on standard Mie scattering theory. This theory is most appropriate for diameter distributions ranging from less than μm to multimicronic; this makes it possible to determine the "effective" particle size. This theory is described in particular in the publication by Van de Hulst, HC, Light Scattering by Small Particles, Chapters 9 and 10, Wiley, New York, 1957.
[0114] D
[50] represents the maximum diameter of 50 volume percent of the particles.
[0115] In the scope of the present invention, the inorganic pigment is more specifically iron oxide and / or titanium dioxide. More specifically, examples include titanium dioxide and iron oxide coated with aluminum stearoyl glutamate, for example, sold by Miyoshi Kasei under reference code NAI®.
[0116] In the present invention, an inorganic pigment that can be used is also a pearlescent pigment.
[0117] The term “pearlescent pigment” should be understood to mean any colored or colorless particles of any shape that exhibit a coloration effect through light interference, which may or may not have iridescence, and are produced or synthesized in the shells of certain mollusks.
[0118] The pearlescent pigments can be selected from pearlescent pigments such as titanium mica coated with iron oxide, titanium mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with organic dyes, and bismuth oxychloride-based pearlescent pigments. They may also be mica particles in which at least two continuous layers of metal oxides and / or organic dyes are superimposed on their surface.
[0119] Examples of pearlescent luster agents include natural mica coated with titanium dioxide, iron oxide, natural pigments, or bismuth oxychloride.
[0120] The pearlescent agent may, more specifically, exhibit a yellow, pink, red, reddish-brown, orange, brown, gold, and / or copper color or a glint of these colors.
[0121] Among the pigments that can be used in accordance with the present invention, there may be those that have optical effects different from simple conventional coloring effects, i.e., the unified and stabilized effects produced by conventional colorants such as monochromatic pigments. Within the scope of the present invention, the term “stabilized” means that there is no effect of the color changing in various ways with respect to the observation angle or in response to temperature changes.
[0122] For example, the material may be selected from particles having a metallic sheen, goniochromatic colorants, photodiffractive pigments, thermochromic colorants, optical glossants, and even fibers, particularly photointerference fibers. Naturally, these various materials can be combined to exhibit two effects simultaneously, and even novel effects according to the present invention.
[0123] According to another specific embodiment of the present invention, the composition comprises at least one pigment coated with at least one lipid-soluble or hydrophobic compound.
[0124] This type of pigment is particularly advantageous. As long as they are treated with hydrophobic compounds, they exhibit a dominant affinity for the oily phase, which can then transport them.
[0125] The coating may also include at least one further non-lipophilic compound.
[0126] Within the meaning of the present invention, "coating" of a pigment according to the present invention generally refers to the whole or partial surface treatment of a pigment by a surface material that is absorbed onto, adsorbed onto, or bonded to the pigment.
[0127] Surface-treated pigments can be prepared according to surface treatment techniques with chemical, electrical, mechanochemical, or mechanical properties well known to those skilled in the art. Commercially available products may also be used.
[0128] Surface treatment agents can be absorbed onto, adsorbed onto, or adhered to pigments by evaporation of the solvent, chemical reactions, and the formation of covalent bonds.
[0129] According to one alternative, the surface treatment consists of a pigment coating.
[0130] The coating may amount to 0.1% to 20% by mass, and particularly 0.5% to 5% by mass, of the total mass of the coated pigment.
[0131] The coating may be produced by, for example, selectively heating and simply mixing solid particles and a liquid surface treatment agent while stirring, before incorporating the particles into other ingredients of a makeup or care composition, thereby adsorbing the liquid surface treatment agent onto the surface of the solid particles.
[0132] The coating may be produced, for example, by chemically reacting a surface treatment agent with the surface of solid pigment particles to create a covalent bond between the surface treatment agent and the particles. This method is described in particular in U.S. Patent No. 4,578,266.
[0133] Chemical surface treatment may consist of diluting a surface treatment agent with a volatile solvent, dispersing a pigment in this mixture, and then slowly evaporating the volatile solvent, thereby depositing the surface treatment agent onto the surface of the pigment.
[0134] If the pigment includes an oil-lipid or hydrophobic coating, this is preferably present in the fatty phase of the composition according to the present invention.
[0135] According to certain embodiments of the present invention, pigments may be coated in accordance with the present invention with at least one compound selected from silicone-based surface treatment agents; fluorine-based surface treatment agents; fluorosilicone-based surface treatment agents; metal soaps; N-acyl amino acids or salts thereof; lecithin and its derivatives; isopropyltriisostearyl titanate; isostearyl sebacate; natural plant-based or animal-based waxes; polar synthetic waxes; fatty esters; phospholipids; and mixtures thereof.
[0136] According to certain embodiments of the present invention, pigments can be coated with hydrophilic compounds.
[0137] The hydrophilic compound, which enables surface treatment of the pigment to optimize its dispersion in the aqueous phase, is more specifically selected from biological polymers, carbohydrates, polysaccharides, polyacrylates, or polyethylene glycol derivatives.
[0138] Examples of biomacromolecules include polymers based on carbohydrate-type monomers.
[0139] More specifically, these include biosaccharide gums; chitosan and its derivatives, such as butoxychitosan, carboxymethylchitosan, carboxybutylchitosan, chitosan gluconate, chitosan adipate, chitosan glycolate, chitosan lactate, etc.; chitin and its derivatives, such as carboxymethylchitin or chitin glycolate, etc.; cellulose and its derivatives, such as cellulose acetate, etc.; microcrystalline cellulose; sodium hyaluronate; soluble proteoglycans; galactoarabinan; glycosaminoglycans; glycogen; sclerotium gum; dextran; starch and its derivatives, such as distarch phosphate, etc.; and mixtures thereof.

[0143] The pigments may also be in the form of composite pigments, as described in European Patent No. 1184426. These composite pigments may, in particular, consist of particles comprising an organic pigment and an inorganic core that is at least partially coated with at least one binder resulting in the fixation of the organic pigment to the core.
[0144] Pigments can also be lakes. The term "lake" is understood to mean an insoluble dye adsorbed on insoluble particles, and the resulting aggregate remains insoluble during use.
[0145] Examples of inorganic substrates for adsorbing dyes include alumina, silica, sodium calcium borosilicate, or calcium aluminum borosilicate and aluminum.
[0146] Among organic dyes, cochineal carmine is one example.

[0148] Of particular note is that organic pigments can also be coated. In this case, one can refer to the corresponding explanation given for inorganic pigments.
[0149] water soluble dye According to a specific embodiment of the present invention, the colorant is a water-soluble dye.
[0150] For the purposes of this invention, the term "water-soluble dye" means any natural or synthetic, generally organic compound that is soluble in an aqueous phase or a water-miscible solvent and is coloring.

More specifically, these compounds are obtained from fruits such as grapes, blackberries, and plums, or from vegetables such as red cabbage, red radish, or purple sweet potato. Therefore, they are basically responsible for the lilac, red, blue, and purple colors of flowers, fruits, leaves, seeds, and roots.

Advantageously, the melting point is 90°C or lower, more specifically 80°C or lower, and preferably 70°C or lower.
[0161] The melting point of solid fatty substances can be measured using a differential scanning calorimeter (DSC), such as the DSC Q100 sold by TA Instruments with TA Universal Analysis software.
[0162] The measurement protocol is as follows: A sample of approximately 5 mg of solid fatty material is placed in a "hermetic aluminum capsule" crucible.
[0163] The sample is subjected to a first temperature increase, which is expanded from 20°C to 120°C at a heating rate of 2°C / min up to 80°C, then the sample is left at an isothermal temperature of 100°C for 20 minutes, then cooled from 120°C to 0°C at a cooling rate of 2°C / min, and finally subjected to a second temperature increase, which is expanded from 0°C to 20°C at a heating rate of 2°C / min.
[0164] The melting point of a solid fatty substance is the value of the peak of the most endothermic observed on the melting curve, which represents the variation in the absorbed power difference as a function of temperature.

[0188] Regular additional cosmetic ingredients The compositions according to the present invention may also include any of the following common cosmetic ingredients, which can be selected from fillers; lipid-soluble thickeners, which may or may not be hydrophobic, such as silica; clays, which may or may not be hydrophobic, which may or may not be hydrophobic; antioxidants; lipid-soluble or hydrophilic film-forming polymers other than ethylcellulose; fragrances; preservatives; neutralizing agents, buffering agents; sunscreens; sweeteners; vitamins; free radical scavengers; scavengers; and mixtures thereof.
[0189] Needless to say, those skilled in the art will take care in selecting these optional additional components and / or amounts such that the advantageous properties of the composition according to the present invention are not adversely affected or substantially adversely affected.
[0190] Preparation of this composition The emulsion is obtained by using means that are conventional to those skilled in the art for preparing water-in-oil emulsions.
[0191] Therefore, an aqueous phase and an oily phase of the emulsion are prepared on the one hand, and these two phases thus obtained are brought into contact with each other while stirring thoroughly to obtain a homogeneous composition; preferably the aqueous phase is introduced into the oily phase.
[0192] Typically, ethylcellulose is brought into contact with a first oil, and then, preferably, after a homogeneous mixture is obtained, other compounds in the oily phase, including optional solid compounds of the type of wax or paste, are added.
[0193] Depending on their properties, colorants may be present in the aqueous or lipid-soluble phase, or even a combination of these two possibilities, and can be added at the time the emulsion is obtained.
[0194] The temperature at which the oily phase is prepared typically varies between 25°C and 110°C, preferably between 70°C and 90°C, depending on the properties of its constituent components.
[0195] The aqueous phase is generally prepared at a temperature of 40-90°C.
[0196] Similarly, the mixing of the two phases takes place, more specifically, at temperatures below 100°C, and generally below 90°C. For example, emulsions are formed at temperatures between 40 and 90°C.
[0197] Once the emulsion is obtained, it is conventionally cooled or cooled, preferably while stirring, to a temperature suitable for sealing in a suitable container.
[0198] Application method Another subject of the present invention is a method for applying makeup and / or care for the lips, comprising the application of the above-described composition.
[0199] The compositions according to the present invention can be scooped up and applied by any suitable means, or otherwise by fingers, whether or not an applicator is used which includes, for example, an applicator head that is at least partially flocked.
[0200] Throughout this specification, including the claims, the phrase “comprising a” should be understood to mean “comprising at least one” unless otherwise specified.
[0201] The expressions "between ~ and ~" and "the range from ~ to ~" should be understood to mean including the endpoints unless otherwise specified.
[0202] Furthermore, the total amount of the components of this composition corresponds to 100% by mass of this composition.
