Description

Title of the invention: Composition comprising ethyl cellulose, a mono-alcohol, a volatile hydrocarbon oil, a non-volatile alkane oil, a mono- or diester of fatty acid and polyglycerol and a dialkyl carbonate Technical field

[0001] The present invention aims to provide for the field of care and / or makeup of keratin materials such as the skin, in particular areas of the face, in particular the eyelids or cheeks. It also relates to a process for care and / or makeup of human keratin materials, such as the skin, in particular areas of the face, in particular the eyelids or cheeks in which said composition is applied.

[0002] Cosmetic makeup compositions are commonly used to provide an aesthetic color to keratin materials such as skin, but also to beautify irregular skin by hiding spots and dyschromia, reducing the visibility of relief imperfections such as pores and wrinkles. Many formulations have been developed to date.

[0003] The vast majority of eyeshadows or blushes on the cosmetics market are products in the form of powders whose shine is provided exclusively by reflective particles, in particular interference pigments such as mother-of-pearls having a natural substrate such as mica or a synthetic substrate such as a borosilicate or a synthetic fluorphlogopite. This type of composition does not make it possible to obtain a sufficiently intense shine.

[0004] Among other current makeup formulations, there are - anhydrous creams with a high content of fatty substances such as oils or waxes such as the commercial product Longwear Cream Eyeshadow® by Chanel; - compact powders with a high binder content made from oils such as Chanel Longwear Powder Eyeshadow® and Ombre Première Cruise Gloss Top Coat Eyeshadow®; - hot-poured solid anhydrous formulas, particularly in the form of crayons based on ester oils and waxes, such as the commercial product Jumbo Crayon® from Nyx;

[0005] - gloss-type formulas such as the commercial product Eye Gloss Smudger® from Yves Saint-Laurent, similar to lip glosses, colored or not, and generally containing a high content of hydrogenated polyisobutene.

[0006] In all these types of anhydrous galenics, the shiny effect is provided by the oils (esters, silicones, hydrogenated polyisobutene, isododecane), in the presence or absence of reflective particles such as pearls or glitter. Despite providing good shine, these products tend to produce an uncomfortable sticky effect, migrate easily into the creases of the eyelid or transfer and therefore have little staying power over time.

[0007] There are also liquid aqueous formulas in the form of a more or less gelled oil-in-water emulsion, such as the commercial products Eye Tint Liquid Eyeshadow® by Georgio Armani, Ombre Première Laque® by Chanel and Glitter & Glow Liquid Eyeshadow® by Stila Styles, which are based on a high content of oils and pearls. However, the wet shine appearance provided by the water when applying these products generally disappears after a few moments, leaving only a particulate shine due to the pearls after drying, the residual deposit of the formula being matte.

[0008] To date, the only category of cosmetic products with a fast-drying, transfer-free, high-shine deposit without the aid of reflective particles is nail polish. But these products are not suitable for application to the face, particularly on the eyelids or cheeks. Indeed, such products could lead to tolerance problems and would produce a film after application with a strong, uncomfortable rigidity.

[0009] There remains a need to find new compositions for the care and / or makeup of keratin materials, in particular eyeshadows or blushers making it possible to obtain intense shine without necessarily resorting to reflective particles, having good staying power over time, with a very low sticky effect or even no sticky effect and not transferring or migrating into the folds of the eyelid, very quickly after application.

[0010] During its research, the applicant unexpectedly discovered that these objectives could be achieved with an anhydrous composition for the care and / or makeup of keratin materials such as the skin, in particular areas of the face, in particular the eyelids or cheeks, comprising, preferably in a physiologically acceptable medium: (a) ethylcellulose; and (b) at least one mono-alcohol, linear or branched, containing 2 to 6 carbon atoms, and

[0011] c) at least one monoester or diester of linear or branched C12-C18 carboxylic acid and polyglycerol comprising from 2 to 6 units, preferably 2 or 3 glycerol units; and

[0012] d) a liquid fatty phase comprising (i) at least one volatile hydrocarbon oil; and (ii) at least one non-volatile alkane oil; and iii) at least one non-volatile ester oil chosen from C16-C22 dialkyl carbonates of formula R'COOR2 in which R1 and R2, independently, denote a linear or branched alkyl radical having from 1 to 16 atoms such that the total number of carbon atoms present in the radicals R1 and R2 is from 16 to 22; said composition being in the form of a gel whose G* modulus (viscoelastic modulus) is between 100 and 3000 Pa for a phase angle between 30 and 60°.

[0013] This discovery is the basis of the invention.

[0014] The present invention relates to an anhydrous composition for the care and / or makeup of keratin materials such as the skin, in particular areas of the face, in particular the eyelids or cheeks, comprising, preferably in a physiologically acceptable medium: (a) ethylcellulose; and (b) at least one mono-alcohol, linear or branched, containing 2 to 6 carbon atoms, and

[0015] c) at least one monoester or diester of linear or branched C12-C18 carboxylic acid and polyglycerol comprising from 2 to 6 units, preferably 2 or 3 glycerol units; and

[0017] The invention relates to a process for coating keratin materials such as the skin, in particular areas of the face, in particular the eyelids or cheeks, characterized in that it comprises the application to the keratin materials of a composition as defined above.

[0018] The invention relates more particularly to a process for making up and / or caring for keratin materials such as the skin, in particular areas of the face, in particular the eyelids or cheeks, characterized in that it comprises the application to the skin of a composition as defined above. Definitions

[0019] In the context of the present invention, by “keratin materials” is meant the skin, in particular areas of the face, more particularly the eyelids or cheeks.

[0020] By "physiologically acceptable" is meant compatible with the skin and / or its appendages, which has a pleasant color, odor and feel and which does not generate unacceptable discomfort (tingling, tightness) likely to deter the consumer from using this composition.

[0021] For the purposes of the present invention, the term "anhydrous" means a composition comprising a content of less than or equal to 5.0% by weight of water, preferably less than or equal to 2.0%, more preferably less than or equal to 1.0% by weight, even more preferably less than or equal to 0.5% by weight relative to the total weight of said composition or even free of water. Where appropriate, such small quantities of water may in particular be provided by ingredients of the composition which may contain residual quantities thereof. Ethylcellulose

[0023] Ethylcellulose is an ethyl ether of cellulose, comprising a chain made up of [3-anhydroglucose] units linked together by acetal bonds. Each anhydroglucose unit has three replaceable hydroxyl groups, all or part of these hydroxyl groups being able to react according to the following reaction: RONa + C2H5Cl → ROC2H5 + NaCl, where R represents a cellulose radical. Total substitution of the three hydroxyl groups would lead, for each anhydroglucose unit, to a degree of substitution of 3, in other words, to an alkoxy, in particular ethoxy, content of 54.88%.

[0024] The ethylcellulose polymers used in a cosmetic composition according to the invention are preferably polymers having a degree of substitution in ethoxy groups ranging from 2.5 to 2.6 per anhydroglucose unit, in other words comprising a content of ethoxy groups ranging from 44% to 50%.

[0069] Preferably, the compositions of the invention have: 1) a stickiness value less than or equal to 0.01 Ns, preferably less than or equal to 0.005 N.s; and 2) a gloss greater than or equal to 50 gloss units at 60°, preferably ranging from 60 to 85 gloss units; and 3) a setting time of the surface of the film formed by the composition on the keratin material or a synthetic substrate, preferably less than 1 minute, more preferably less than or equal to 30 seconds. A) Tights measurement protocol

[0070] The composition is deposited in the form of a film in a silicone mold 2.5 cm wide and 5.5 cm long (for example, of the Silikomart 20.026.00.0060 SF026® cake mold type). 1.7 + / - 0.02 g of the composition is weighed into the silicone mold. The product is spread using a flat spatula, such as, for example, a spatula of the Labo Moderne, BC3219 Spatule® type, so as to obtain a homogeneous layer over the entire bottom of the mold. The mold with the product is stored in a space protected from drafts, such as a cupboard drawer, and left to dry for 24 hours.

[0071] The film is carefully removed from the silicone mold and placed flat on a flexible sheet of the Supplale® type such as, for example, the commercial reference Soudotique PG SARL® or DFSUP10075® beige.

[0072] The assembly is positioned on the platform of a MicroSystem TA.XT Plus® Stable Texturometer equipped with a 5kg sensor, an SMS P / 5S® spherical traction mobile and Exponent Connect® software. The parameters of the compression tests with maintenance over time are as follows:

[0073] Approach speed (or pre-speed): 0.5 mm / s; Speed ​​(from contact detection): 0.1 mm / s; Force (and corresponding pressure): 0.01 Newtons; Depth of insertion: 0.15 mm; Hold time: 5 seconds; Withdrawal speed (or post-speed): 2 mm / s.

[0074] Four successive measurements are carried out by positioning the film so that the measurement points are equally distributed over the surface of the film, avoiding the most irregular areas. For each test, the curve measuring the force exerted on the mobile as a function of time is plotted.

[0075] The adhesive is characterized by the detachment work measured during unloading (tensile phase).

[0076] The adhesiveness value of the composition, expressed in newton-seconds (Ns), corresponds to the average of the area values ​​of the four adhesive force measurements as a function of time during the movement of the mobile (the area delimited between the curve of points measured during the upward movement of the mobile – negative force values ​​– and the x-axis, until this curve reaches a zero force value). B) Gloss measurement protocol

[0077] The sample is spread as a 50.8pm film on a Byko Chart 2A® or Penopac IA® type contrast card from BYK using an automatic film spreader of the Byko-Drive XL® type from BYK equipped with a film spreading bar such as a variable slit height square 5353® from BYK, set for a slit height of 50.8pm.

[0078] The contrast card is placed on the applicator platform and the 50.8 pm slit-side bar is placed on the contrast card, at the level of the information zone to be filled in. Approximately 2g of product is deposited just in front of the bar. The automatic applicator and the movement of the bar are started so as to ensure the deposition of a regular film of the expected thickness.

[0079] The film is left to dry at 25°C for 15 minutes.

[0080] The gloss of the film applied to the black areas of the contrast map is measured with an angle of incidence of 60°; this is expressed in gloss units.

[0081] The gloss unit is a measurement scale of a glossmeter (e.g., Konica Minolta's Rhopoint IQ-S®), established from a reference standard of highly polished black glass, with a defined refractive index and specular reflectance of 100 gloss units at a given angle, with the minimum point set at 0 for a perfectly matte surface. This scale is suitable for most coatings and non-metallic materials such as paint and plastic.

[0082] The measurement can be repeated over time to assess the gloss retention. C) Protocol for assessing the setting time

[0083] When the product is applied in a thin layer (on skin or on a synthetic surface), the surface of the deposit sets slightly, by forming a very thin, flexible but non-sticky film, which prevents the product from being transferred to another surface. This can be likened to a drying time.

[0084] 0.05g + / -0.01g of the sample is deposited on the inner surface of the forearm, which is then spread quickly (in 2-3 seconds) in a thin layer with the finger to form a film of homogeneous thickness over a surface of approximately 8 cm2.

[0085] The stopwatch is started and the surface solidification of the deposit is evaluated every 10 seconds or so by lightly pressing the pulp of the index finger on it and then observing the presence or absence of any trace of product that has transferred onto the index finger.

[0086] The freezing time is the time at which no further transfer of product from the forearm to the index finger is observed. D) Rheological properties of the product

[0087] According to a preferred embodiment, the composition is in the form of a gel whose modulus G* (viscoelastic modulus) is between 100 and 3000 Pa for a phase shift angle of between 30 and 60°, more particularly between 500 and 2800 Pa, for a phase shift angle of between 30 and 50°.

[0088] Gels, like all polymerized systems, exhibit viscoelastic behavior.

[0089] This type of behavior can be characterized from fining or relaxation experiments, or by dynamic tests where a sinusoidal stress (or strain) is applied. In the present case, the viscoelastic properties (G* and delta) are measured with an imposed stress rheometer and the values ​​are taken on the viscoelastic plateau at 25 °C.

[0090] The measurements are carried out using an imposed stress rheometer (ARG2® from TA Instruments). The measurement geometry used is the sandblasted cone-plate of 35 mm diameter with an angle of 2°. The sample is stressed with sinusoidal stresses of increasing amplitude at a frequency of 1 hertz, over a stress range from 0.1 to 1000 Pa. The resistance opposed by the sample to the imposed deformation makes it possible to obtain the curves of the consistency G* and the solid / liquid character ô as a function of the stress r. The main data collected are the G* at the plateau (consistency) and the phase shift angle delta (solid / liquid character). Pigments

[0091] According to a particular embodiment of the invention, the composition additionally comprises at least one pigment.

[0092] The term “pigments” means white or colored particles, mineral or organic, insoluble in an aqueous medium, intended to color and / or opacify the composition and / or the resulting deposit. These pigments may be white or colored, mineral and / or organic. They may be coated or not coated with a surface treatment agent,

[0093] Preferably, the composition comprises at least 0.01% by weight of pigment(s), more preferably from 0.1 to 3% by weight of pigment(s), in particular from 0.2 to 1% by weight and preferably from 0.2 to 0.5% by weight of pigment(s), relative to the total weight of said composition.

[0094] According to a particular embodiment, the pigments used according to the invention are chosen from mineral pigments.

[0095] By "mineral pigment" is meant any pigment that meets the definition of the Ullmann encyclopedia in the inorganic pigment chapter.

The following mineral pigments may also be used: Ta2O5, Ti3O5, Ti 2O3, TiO, ZrO2 in mixture with TiO2, ZrO2, Nb2O5, CeO2, ZnS.

[0096] The size of the pigment useful in the context of the present invention is generally greater than 100 nm and can range up to 10 qm, preferably from 200 nm to 5 qm, and more preferably from 300 nm to 1 qm.

[0097] According to a particular embodiment of the invention, the pigments have a size characterized by a D

[50] greater than 100 nm and up to 10 qm, preferably from 200 nm to 5 qm, and more preferably from 300 nm to 1 qm.

[0098] The sizes are measured by static light scattering using a commercial particle size analyzer, the Master Sizer 3000® 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 are processed based on the classical Mie scattering theory. This theory is best suited for size distributions ranging from submicron to multimicron, and it allows for the determination of an "effective" particle diameter. This theory is notably described in Van de Hulst, H.C., "Light Scattering by Small Particles," Chapters 9 and 10, Wiley, New York, 1957.

[0099] D

[0100] In the context of the present invention, the mineral pigments are more particularly iron oxides and / or titanium dioxide, coated or uncoated.

[0101] As mineral pigments which can be used in the invention, mention may also be made of: mother-of-pearl.

[0102] By “mother-of-pearl”, one must understand colored particles of any shape, iridescent or not, in particular, produced by certain molluscs in their shell or synthesized and which exhibit a color effect by optical interference.

[0103] The nacres can be selected from pearlescent pigments, such as titanium mica coated with an iron oxide, titanium mica coated with bismuth oxychloride, titanium mica coated with chromium oxide, titanium mica coated with an organic dye, as well as pearlescent pigments based on bismuth oxychloride. They can also consist of mica particles on the surface of which at least two successive layers of metal oxides and / or organic coloring materials are superimposed.

[0104] Examples of mother-of-pearls that may also be mentioned include natural mica coated with titanium oxide, iron oxide, natural pigment or bismuth oxychloride.

[0105] Among the mother-of-pearls available on the market, we can cite the TIMICA®, FLAMENCO® and DUOCHROME® mother-of-pearls (based on mica) marketed by the company ENGELHARD, the TIMIRON® mother-of-pearls marketed by the company MERCK, the PRESTIGE® mica-based mother-of-pearls marketed by the company ECKART and the SUNSHINE® synthetic mica-based mother-of-pearls marketed by the company SUN CHEMICAL.

[0106] Mother-of-pearl may in particular have a yellow, pink, red, bronze, orange, brown, gold and / or copper colour or reflection.

[0107] By way of illustration of the mother-of-pearls that can be used in the context of the present invention, we can, in particular, mention the gold-colored mother-of-pearls, in particular, marketed by the company ENGELHARD, under the name of Brillant gold 212G® (Timica), Gold 222C® (Cloisonne), Sparkle Gold® (Timica), Gold 4504® (Chromalite) and Monarch Gold 233X® (Cloisonne); the bronze mother-of-pearls, in particular, marketed by the company MERCK under the name Bronze fine® (17384) (Colorona) and Bronze® (17353) (Colorona) and by the company ENGELHARD under the name Super bronze (Cloisonne); orange mother-of-pearls, in particular, marketed by the company ENGELHARD under the name Orange 363C® (Cloisonne) and Orange MCR 101® (Cosmica) and by the company MERCK under the name Passion Orange® (Colorona) and Matte Orange (17449) ® (Microna);brown-tinted mother-of-pearl, in particular, marketed by the company ENGELHARD under the name Nu-Antique Copper 340XB® (Cloisonne) and Brown CL4509® (Chromalite); copper-reflecting mother-of-pearl, in particular, marketed by the company ENGELHARD under the name Copper 340A® (Timica); red-reflecting mother-of-pearl, in particular, marketed by the company MERCK under the name Sienna fine® (17386) (Colorona); yellow-reflecting mother-of-pearl, in particular, marketed by the company; ENGELHARD under the name Yellow (4502) ® (Chromalite); red mother-of-pearl with a gold sheen, in particular, marketed by ENGELHARD under the name Sunstone G012® (Gemtone); pink mother-of-pearl, in particular, marketed by ENGELHARD under the name Tan Opale G005® (Gemtone); black mother-of-pearl with a gold sheen, in particular, marketed by ENGELHARD under the name Nu Antique Bronze 240 AB® (Timica), blue mother-of-pearl, in particular, marketed by MERCK under the name Matte Blue® (17433) (Microna), white mother-of-pearl with a silver sheen, in particular, marketed by MERCK under the name Xirona Silver® and orange-pinkish-golden-green mother-of-pearl, in particular, marketed by MERCK under the name Indian Summer® (Xirona) and their mixtures.

[0108] Among the pigments usable according to the invention, one can also mention those with an optical effect different from a simple conventional hue effect, that is to say, unified and stabilized such as produced by conventional coloring materials, such as, for example, monochromatic pigments. For the purposes of the invention, "stabilized" means devoid of any effect of color variability with the angle of observation or in response to a change in temperature.

[0109] For example, this material can be chosen from metallic-reflecting particles, goniochromatic coloring agents, diffracting pigments, thermochromic agents, optical brighteners, and, in particular, interference fibers. Of course, these different materials can be combined in such a way as to provide the simultaneous manifestation of two effects, or even a new effect according to the invention.

[0110] The particles with a metallic sheen that can be used in the invention are in particular chosen from:

[0111] - particles of at least one metal and / or at least one metal derivative,

[0112] - particles comprising an organic or mineral substrate, single-material or multi- materials, covered at least partially by at least one layer with a metallic sheen comprising at least one metal and / or at least one metallic derivative, and

[0113] - mixtures of said particles.

[0114] Among the metals that may be present in said particles, there may be mentioned for example Ag, Au, Cu, Al, Ni, Sn, Mg, Cr, Mo, Ti, Zr, Pt, Va, Rb, W, Zn, Ge, Te, Se and their mixtures or alloys. Ag, Au, Cu, Al, Zn, Ni, Mo, Cr, and their mixtures or alloys (for example, bronzes and brasses) are preferred metals.

[0115] By “metal derivatives” is meant compounds derived from metals, in particular, oxides, fluorides, chlorides and sulfides.

[0116] As an illustration of these particles, mention may be made of aluminum particles, such as those marketed under the names STARBRITE 1200 EAC® by the SIBERLINE company and METALURE® by ECKART company.

[0117] Mention may also be made of metallic copper powders or mixtures of alloys, such as the references 2844 marketed by the company RADIUM BRONZE, metallic pigments, such as aluminum or bronze, such as those marketed under the names ROTOSAFE 700® from the company ECKART, particles of aluminum coated with silica marketed under the name VI-SIONAIRE BRIGHT SILVER® from the company ECKART and particles of metallic alloy, such as bronze powders (copper and zinc alloy) coated with silica marketed under the name Visionaire Bright Natural Gold® from the company Eckart.

[0118] It may also be particles comprising a glass substrate such as those marketed by the company NIPPON SHEET GLASS under the names ML CROGLASS METASHINE®.

[0119] The goniochromatic coloring agent may be selected, for example, from interference multilayer structures and liquid crystal coloring agents.

[0120] Examples of symmetrical interference multilayer structures that can be used in compositions produced in accordance with the invention are, for example, the following structures: Al / SiO2 / Al / SiO2 / Al, pigments having this structure being marketed by the company DUPONT DE NEMOURS; Cr / MgF2 / Al / MgF2 / Cr, pigments having this structure being marketed under the name CHROMAFLAIR® by the company FLEX; MoS2 / SiO2 / Al / SiO2 / MoS2; Fe2O3 / SiO2 / Al / SiO2 / Fe2O3, and Fe2O3 / SiO2 / Fe2O3 / SiO2 / Fe2O3, pigments having these structures being marketed under the name SICOPEARL® by the company BASF; MoS2 / SiO2 / mica-oxide / SiO2 / MoS 2 ; Fe2O3 / SiO2 / mica-oxide / SiO2 / Fe2O3; TiO2 / SiO2 / TiO2 and TiO2 / Al2O3 / TiO2; SnO / TiO2 / SiO2 / TiO2 / SnO; Fe2O3 / SiO2 / Fe2O3; SnO / mica / TiO2 / SiO2 / TiO2 / mica / SnO, pigments having these structures being marketed under the name XIRONA® by the company MERCK (Darmstadt).For example, these pigments may be the silica / titanium oxide / tin oxide structure pigments marketed under the name XIRONA MAGIC® by MERCK, the silica / brown iron oxide structure pigments marketed under the name XIRONA INDIAN SUMMER® by MERCK and the silica / titanium oxide / mica / tin oxide structure pigments marketed under the name XIRONA CARRIBEAN BLUE® by MERCK. Mention may also be made of the INFINITE COLORS pigments from SHISEIDO. Depending on the thickness and nature of the different layers, different effects are obtained. Thus, with the Fe2O3 / SiO2 / Al / SiO2 / Fe2O3 structure, the color goes from gold-green to gray-red for SiO2 layers of 320 to 350 nm; from red to gold for SiO2 layers of 380 to 400 nm; from violet to green for SiO2 layers from 410 to 420 nm; from copper to red for SiO2 layers from 430 to 440 nm.

[0131] The coating may represent from 0.1% to 20% by weight, and in particular from 0.5% to 5% by weight. % by weight of the total weight of the coated pigment.

[0132] The coating can be carried out for example by adsorption of a liquid surface agent on the surface of the solid particles by simple mixing with stirring of the particles and said surface agent, optionally hot, prior to the incorporation of the particles into the other ingredients of the makeup or care composition.

[0133] The coating can be carried out for example by chemical reaction of a surfactant with the surface of the solid pigment particles and creation of a covalent bond between the surfactant and the particles. This method is notably described in US patent 4,578,266.

[0167] According to one embodiment, a composition of the invention may advantageously be in the form of a care and / or makeup composition for keratin materials such as the skin, in particular areas of the face, in particular the eyelids or cheeks.

[0168] Thus, according to a sub-mode of this embodiment, a composition of the invention can advantageously be presented in the form of a base composition for makeup.

[0169] A composition of the invention may advantageously be in the form of a makeup composition for the skin and in particular for the face. It may thus be an eyeshadow or a blush.

[0170] Such compositions are in particular prepared according to the general knowledge of those skilled in the art.

[0171] The invention is illustrated in more detail by the examples and figures presented below. Unless otherwise indicated, the quantities indicated are expressed as a mass percentage.

[0172] Examples 1 (invention) and examples 1a and 1b (outside the invention): eyeshadows

[0173] Composition 1 according to the invention as well as compositions outside the invention 1a, 1b were prepared according to the preparation protocols described below.

[0174] [Tableauxl] Ingredients Example 1% by weight Example la% by weight Example 1b % by weight ETHYLCELLULOSE (AQUALON EC N7 PHARM®-ASHLAND) 20 20 20 DICAPRYLYL CARBONATE (CETIOL CC®- BASF) 10 10 NEOPENTYL GLYCOL DICAPRATE (ESTEMOL N-01, NISSHIN OILLIO) 10 POLYGLYCERYL-3 DIL SOSTEARATE (LAMEFORM TGI® - BASF) 30 30 30 SQUALANE (NEOSSANCE SQUALANE®-AMYRIS) 10 0 10 ALCOHOL 15 15 15 ISODODECANE QSP 100 QSP 100 QSP 100 Preparation protocol

[0175] In a beaker, the non-volatile ester oil (dicaprylyl carbonate or neo-pentylglycol dicaprate), the Polyglyceryl-3 Diisosterate were introduced, then the ethyl cellulose was added. The mixture was then homogenized under deflocculating stirring, so as to deagglomerate and thoroughly wet the polymer. At this stage, a thick, creamy-white suspension was obtained. The alcohol was added, then homogenized under deflocculating stirring until a more or less transparent, colorless to pale yellow gel was formed. The isododecane and, if necessary, the squalane were slowly added in a steady stream so as to allow their gradual integration into the gel. Once all of these solvents had been introduced, stirring continued until a homogeneous gel was obtained.

[0176] The following characteristics of each composition were evaluated at 25°C for each of examples 1 (invention) and countertype examples outside the invention 1a, 1b according to the measurement protocols as detailed previously:

[0177] - the sticky value

[0178] - shine at 60°, 15 min, 2 hours and 7 hours after application

[0179] - the freezing time

[0180] The results are shown in the table below.

[0181] [Tables2] Measured characteristics Tack value (Newtons.seconds) Gloss 60° (gloss units) Setting time (seconds) at 15 minutes at 2 hours at 7 hours Example 1 (invention) with Dicaprylyl carbonate and squalane 0.4+ / -0.1 72 + / -4 72 + / -2 70 + / -4 20 Example 1a (not invention) with Dicaprylyl Carbonate without squalane 0.7+ / -0.1 81 + / -2 80 + / -2 79+ / -1 30 Example 1b (not invention) with Neopentylglycol Dicaprate and squalane Not measurable: film tears 65 + / -3 63 + / -6 59 + / -6 80

[0182] The results showed that Example 1 of the invention comprising Ethyl cellulose, Polyglyceryl-3 Diisostearate, ethanol, isododecane, squalane and as non-volatile ester oil dicaprylyl carbonate produces after application a film with an intense shine for 7 hours, satisfactory adhesion, low tack and a short film surface setting time of less than or equal to 30 seconds.

[0183] The results showed that the counter-type example outside the invention, not containing squalane, produced a stickier film after application with a longer surface setting time. They thus confirm the technical contribution of squalane to reducing the film's stickiness.

[0184] The results showed that the counter-type example 1b, containing Neopentylglycol Dicaprate as a non-volatile ester oil, produced a less glossy film with a significantly longer surface setting time. Furthermore, example 1b failed to demold because it tore due to a lack of cohesion, making it impossible to measure its stickiness.
