Description

Title of the invention: Compact powder without talc and free mica, based on perlite, at least one spherical filler, non-volatile oils, an amorphous hydrocarbon sequence copolymer and a particulate colorant

[0001] The present invention relates to a solid composition in the form of a compact powder, in particular comprising a physiologically acceptable medium, in particular for coating keratinous materials, more particularly for makeup and / or care of keratinous materials, such as skin, said compact powder being prepared by a wet process.

[0002] Skin care and / or makeup compositions are generally used to give an attractive color to the skin, such as the face, but also to mask skin imperfections, such as redness, marks, fine lines and wrinkles.

[0003] The aforementioned powders are primarily used to add color, a matte finish, and, for those specifically designed for facial skin, to improve the hold of foundation or, if used alone, to provide coverage (face powder, eyeshadow, blush). These formulations are particularly appreciated by users due to their lightness, softness, and non-sticky or non-greasy feel.

[0004] Generally, these compositions combine a predominant powder phase with a binding phase, most often a liquid oil phase. The powder phase consists primarily of fillers combined with pigments, the quantity of which is adjusted to provide the desired makeup effect, which is generally color-based.

[0005] To obtain a composition in compacted solid form, it is known from the prior art to use compacted makeup powders formed by a mixture of powders with a fatty binder and shaped for example by compression.

[0006] However, these compact powders have the particular disadvantage of being fragile. Thus, as the percentage of pigments increases within the product, its manufacture and compaction become complicated, if not impossible, to achieve on an industrial scale, given the quality and productivity requirements. Furthermore, significant quantities of powdered phase in the compact powder do not provide satisfactory sensory properties when the powder is taken from its packaging and / or when it is applied to the skin. It is also difficult for the formulator to achieve good adhesion of the product to the skin. To overcome these drawbacks, if we increase the amount of oily binder, this composition will tend to wax, that is to say, to harden during use until it prevents removal.

[0007] Among the qualities sought in compact makeup powders, we can mention: - good cohesion and homogenization of the composition, - good impact resistance, - a good texture, - an appropriate hardness, - good adhesion to the skin, - good product application regardless of the applicator (in terms of sufficient quantity of product), - Comfortable application without drying the skin, - good powder retention properties, - good sensory properties at the time of sampling, - good sensory properties at the time of product application.

[0008] It is known in the prior art to manufacture such compositions by using volatile organic solvents (isodecane, isopropanol) implemented in a wet preparation process called a "WET PROCESS," to inject one or more powders of a given color into a respective cup. These solvents allow the powder to become fluid and form a slurry, which is then shaped in a cup and subsequently evaporates.

[0009] Compact powders obtained by this wet process technique have already been proposed in patent EP2928448B1; said powders comprising: - an oil phase greater than or equal to 20% by weight, relative to the total weight of the composition, - a powdery phase greater than or equal to 40% by weight, relative to the total weight of the composition, comprising at least one spherical filler and at least one lamellar filler; the spherical filler(s) and the lamellar filler(s) being present at a respective total weight content such that the weight ratio of the spherical filler(s) to the lamellar filler(s) is greater than or equal to 0.01, preferably between 0.02 and 15.

[0010] A compact powder containing at least: was also proposed in patent application EP3595620 - an oily phase in an amount of at least 20% by weight relative to the total weight of the composition; said oily phase comprising at least one non-volatile, non-phenylated silicone oil; and - a powdered phase in an amount of at least 40% by weight relative to the total weight of the composition; said powdered phase comprising at least mica particles; and - at least one amorphous hydrocarbon sequenced copolymer; said composition not containing any untreated silicone talc particles and being capable of being obtained by a wet preparation process comprising at least the following steps: (i) the oily phase, the amorphous hydrocarbon sequence copolymer, the powdered phase and at least one volatile solvent are mixed to form a slurry; and (ii) the mud is injected into a container (bucket or mold) and shaped by compaction, in particular pressing and / or suction to obtain the composition in powder form.

[0011] These wet-processed compositions include a high quantity of lamellar fillers comprising free mica and talc to maintain good injectability in the manufacturing process and, after evaporation of the volatile solvent, to obtain satisfactory product deposition, cohesion, and impact resistance. The presence of talc in combination with free mica tends to produce compact powders with glossy or satin effects. The applicant observed during its research that reducing or removing the free talc and / or mica from these compact powders to obtain a matte finish affected the deposition, cohesion, and / or sensory properties.

[0012] There remains a need to find new compact powders obtained by wet process, without talc and without mica in free form, having both good injectability in the wet manufacturing process, and after evaporation of the volatile solvent, good product deposition, good cohesion, good matte finish and good sensory appeal.

[0013] The applicant unexpectedly discovered that these objectives could be achieved with a solid composition in the form of a compact powder, including a physiologically acceptable medium and containing at least: (a) an oil phase in an amount of at least 10.0% by weight relative to the total weight of the composition; said oil phase comprising at least one non-volatile oil and b) a powdered phase in an amount of at least 40% by weight relative to the total weight of the composition; said powdered phase comprising at least: i) perlite; and (ii) at least one spherical charge selected from mineral charges, naturally occurring organic charges, and mixtures thereof; and iii) at least one particulate coloring agent; and (c) at least one amorphous hydrocarbon sequenced copolymer; and (d) at least one pigment; said composition not containing talc particles or mica particles in free form and said composition being capable of being obtained by a wet preparation process comprising at least the following steps: 1) The oily phase, the amorphous hydrocarbon sequence copolymer, the powdered phase, and at least one volatile solvent are mixed to form a slurry; and (2) the slurry is injected into a container and shaped by compaction, in particular pressing and / or suction to obtain the composition in the form of a compact powder.

[0014] This discovery is the basis of the invention. Objects of the invention

[0015] Thus, a first object of the present invention is a solid composition in the form of a compact powder, in particular comprising a physiologically acceptable medium and containing at least: (a) an oily phase in an amount of at least 10% by weight relative to the total weight of the composition; said oily phase comprising at least one non-volatile oil and b) a powdered phase in an amount of at least 40% by weight relative to the total weight of the composition; said powdered phase comprising at least: i) perlite; and (ii) at least one spherical charge selected from mineral charges, naturally occurring organic charges, and mixtures thereof; and iii) at least one particulate coloring agent; and (c) at least one amorphous hydrocarbon sequenced copolymer; and (d) at least one pigment; said composition not containing talc particles or mica particles in free form and said composition being capable of being obtained by a wet preparation process comprising at least the following steps: 1) The oily phase, the amorphous hydrocarbon sequence copolymer, the powdered phase, and at least one volatile solvent are mixed to form a slurry; and (2) the slurry is injected into a container and shaped by compaction, in particular pressing and / or suction to obtain the composition in the form of a compact powder.

[0016] A second object of the present invention is a method of coating keratinous materials, in particular skin, and more particularly a method of making up and / or caring for said keratinous materials, comprising applying to them the composition as defined above. Definitions

[0017] In the context of the present invention, "keratinic material" means in particular the skin (face, cheeks, eyelids).

[0018] 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 discomforts (tingling, pulling), likely to deter the consumer from using this composition.

[0019] The term "talc particle" refers to particles of hydroxylated magnesium silicate with the molecular formula Mg3Si4Oio(OH)2, known as talc, belonging to the phyllosilicate chemical family. This talc particle may be untreated or surface-treated, i.e., uncoated or surface-coated, for example, with a surface treatment agent selected from silicones, amino acids, fluorinated derivatives, or any other substance that promotes dispersion and compatibility of the filler within the composition.

[0020] Mica is the name of a family of minerals, belonging to the silicate group, specifically the phyllosilicate subgroup, composed primarily of aluminum and potassium silicate. It is characterized by its layered structure (phyllosilicates), which most often gives rise to flakes and its metallic luster.

[0021] By "free form mica" is meant any natural or synthetic mica not bound to one or more chemical compounds in a composite structure such as nacres comprising mica as a substrate on which are coated metallic oxides such as titanium dioxide, iron oxides, tin oxides.

[0022] By "composition not containing talc particles" is meant any composition containing less than 1.0% by weight relative to the total weight of the composition, or less than 0.5% by weight, or less than 0.1% by weight or even free of talc particles.

[0023] By "composition not containing mica particles in free form", we mean any composition containing less than 1.0% by weight relative to the total weight of the composition, or even less than 0.5% by weight, or even less than 0.1% by weight or even free of mica particles in free form.

[0024] For the purposes of the present invention, the following definitions apply: - By "solid," we mean the state of the composition at room temperature (25°C) and atmospheric pressure (760 mm Hg), that is, a composition of high consistency that retains its shape during storage. Unlike so-called fluid compositions, it does not flow under its own weight. It is advantageously characterized by a hardness as defined below. - by "compact powder", a mass of product whose cohesion is ensured by less so, partly due to compaction or, preferably, pressing during manufacturing. In particular, by performing a measurement with a TA.XT.plus Texture Analyser® sold by Stable Micro Systems, the compacted powder according to the invention can advantageously exhibit a compressive strength between 0.1 and 1 kg, notably between 0.2 and 0.8 kg, referred to the surface area of ​​the mobile used (in this case, 7.07 mm²). This strength is measured by moving a flat-ended cylindrical mobile, SMS P / 3, in contact with the powder, over a distance of 2 mm and at a speed of 0.5 mm / second; more generally, this powder can be obtained by compaction, or preferably by pressing.

[0025] The composition according to the invention advantageously comprises a dry extract content greater than or equal to 95%, better to 98%, or even equal to 100%.

[0026] For the purposes of the present invention, “dry extract content” means the non-volatile matter content.

[0027] The quantity of dry extract (abbreviated DA) of a composition according to the invention is measured using a commercial halogen moisture analyzer, the "HALOGEN MOISTURE ANALYZER HR 73®", from Mettler TOLEDO. The measurement is based on the weight loss of a sample dried by halogen heating and therefore represents the percentage of residual material once the water and volatile matter have evaporated. This technique is fully described in the documentation for the apparatus supplied by Mettler TOLEDO.

[0028] The measurement protocol is as follows:

[0029] Approximately 2 g of the composition, hereinafter referred to as the sample, is spread onto a metal dish which is then placed in the halogen dryer mentioned above. The sample is then subjected to a temperature of 105 °C until a constant weight is obtained. The wet mass of the sample, corresponding to its initial mass, and the dry mass of the sample, corresponding to its mass after halogen heating, are measured using a precision balance.

[0030] The experimental error related to the measurement is on the order of plus or minus 2%. The dry extract content is calculated as follows: Dry Extract Content (expressed as % by weight) = 100 x (Dry Mass / Wet Mass). Powdered phase

[0031] The powdered phase comprises at least: i) perlite; and (ii) at least one spherical charge chosen from among mineral charges, organic charges of natural origin; and iii) at least one particulate coloring agent.

[0032] A solid composition according to the invention has a powder phase content greater than or equal to 40% by weight, and more particularly ranging from 50 to 85% by weight, preferably from 60 to 80% by weight, relative to its total weight of the composition. Perlite

[0033] The perlites usable according to the invention are generally aluminosilicates of volcanic origin and have the following composition - 70.0-75.0% by weight of silica SiO2 - 12.0-15.0% by weight of aluminium oxide oxide A12O3 - 3.0-5.0% sodium oxide Na2O2 - 3.0-5.0% potassium oxide K2O - 0.5-2% iron oxide Fe2O3 - 0.2-0.7% magnesium oxide MgO - 0.5-1.5% calcium oxide CaO - 0.05 - 0.15% titanium oxide TiO2.

[0034] Preferably, the perlite is ground, dried, and then calibrated in a first step. The resulting product, called Perlite Ore, is gray in color and approximately 100 µm in size. The Perlite Ore is then expanded (1000°C / 2 seconds) to produce 30 more or less white particles. When the temperature reaches 850-900°C, the water trapped within the material's structure vaporizes, causing the material to expand relative to its original volume.

[0035] The expanded perlite particles according to the invention can be obtained by the expansion process described in US patent 5,002,698. 35

[0119] According to a preferred form, the composition according to the invention comprises at least one emulsifying non-ionic surfactant of HLB less than or equal to 8.

[0120] For the purposes of the present invention, "emulsifying surfactant" means an amphiphilic surfactant compound, that is to say, having two parts of different polarity. In general, one part is lipophilic (soluble or dispersible in an oil phase), and the other is hydrophilic (soluble or dispersible in water). Emulsifying surfactants are characterized by their HLB (Hydrophilic-Lipophilic Balance) value, where HLB is the ratio of the hydrophilic to the lipophilic part of the molecule. The term HLB is well known to those skilled in the art and is described, for example, in "The HLB System: A Time-Saving Guide to Emulsifier Selection" (published by ICI Americas Inc., 1984). For nonionic emulsifying surfactants usable according to the invention, the HLB generally ranges from 3 to 8. The HLB of the surfactant(s) used according to the invention can be determined by the Griffin method or the Da Vies method.

[0121] The surfactant or emulsifying surfactant(s) may be present in a content ranging from 0.05 to 5% by weight, in particular from 0.05 to 1% by weight relative to the total weight of the composition.

[0124] The cosmetic composition according to the invention is obtained by a wet process comprising the following steps: - the oily phase, the amorphous hydrocarbon sequenced copolymer, the powdered phase and at least one volatile solvent are mixed to prepare a slurry. - the said slurry is injected and then shaped in a container by compaction, in particular pressing and / or aspiration to obtain the final compact powder.

[0125] Preferably, a drying step of the molded mud in the container is also carried out. Mixing stage

[0126] In this step, the components of the oily phase, the components of the powdery phase and the volatile solvent(s) are mixed to prepare the slurry which is a thick suspension of the powdery materials in the liquid formed by the oily phase and the volatile solvent(s).

[0127] According to a first variant, the components of the powder phase and those of the oily phase are first mixed together and then, in a second step, the volatile solvent(s) are added to the mixture obtained.

[0128] According to a second variant, the components of the oily phase and the volatile solvent(s) are first mixed together and then, in a second step, the components of the powdered phase are added to the mixture obtained.

[0129] According to a particular embodiment of the invention, the quantity of oily phase and the quantity of powdery phase are such that the weight ratio of oily phase / powdery phase varies from 20 / 80 to 45 / 55, preferably from 25 / 75 to 40 / 60.

[0130] Volatile organic solvents can be selected from water, C2-C4 monoalcohols such as ethanol and isopropanol, ethers such as dicaprylyl ether, volatile cyclic or linear silicone oils, and hydrocarbons such as isoparaffins like isododecane. Preferably, isoparaffins such as isododecane will be used.

[0131] According to the present invention, the mixing with the powdered phase can be carried out with any type of mixer such as a Lodige type mixer.

[0132] According to a particular embodiment of the invention, the mixed powder can also undergo grinding, for example with an Alpine type pin mill or a cutting robot.

[0133] According to a particular embodiment of the invention, the mixing of volatile solvents can be carried out in any suitable container such as a bowl. It can also be carried out in a planetary mixer. The required dispersion time is not limited and may depend on certain factors such as the type of mixer. For example, if a planetary mixer is used, the dispersion time can vary from 15 to 20 minutes.

[0134] The total quantity of oily phase, powdered phase and volatile solvent is not limited. According to a particular embodiment of the invention, the weight ratio of the total quantity of oily phase and powdered phase to the quantity of volatile solvent(s) can be 5 / 1, preferably 3 / 1, and more preferably 2 / 1.

[0135] If necessary, degassing can be carried out during the mixing step. The oil phase, the powder phase, and the volatile solvent(s) can be mixed in a vacuum chamber. The degassing time may depend on certain factors such as the pressure in the vacuum chamber. It can vary from 15 to 20 minutes. It is preferable to agitate the mud for effective degassing. Formatting stage

[0136] In this step, the slurry is injected and then shaped in a container such as a bucket or mold by compaction, in particular pressing and / or suction. Preferably, this is done by

[0137] A cup or a bowl can be used as a container. The container may have small openings that allow only the solvent to escape by suction.

[0138] Examples of methods for pouring the sludge into the container include injection through the top of the container (“top injection”) or injection through the back of the container (“back injection”).

[0139] According to the so-called “top injection” method, the slurry is poured into the container from above. This method is particularly suitable for the preparation of compact, multicoloured powders.

[0140] According to the so-called “back injection” method, the sludge is injected from the bottom of the container by means of a suitable mechanism for introducing it into the container. In particular, a machine called the Pilot Back Injection machine sold by NANYO CO.LTD is used.

[0141] This injection method is suitable for a wide range of pressed makeup powders and is particularly well-suited for obtaining complex-shaped pressed powders. The powder introduced into the container is molded by compression and / or suction. Preferably, compression and suction are carried out simultaneously.

[0142] Compaction, in particular pressing, can be carried out by applying pressure to the slurry in the container by mechanical means such as a press with a flat or uneven surface (possibility of a textured surface). Suction can be carried out, for example, by reducing the pressure in the container by vacuum. Compaction, in particular pressing and suction, can be repeated several times. If necessary, vibration can be applied to the container and / or the press. Drying stage

[0143] In this step, the molded slurry is dried to obtain a compact powder free of volatile solvent or containing a very small amount of volatile solvent. By drying, the remaining volatile solvent(s) can be completely removed. The drying temperature and time depend on several factors, such as the components of the composition and the type of volatile solvent used. For example, drying can be carried out at a temperature of 60 to 100°C for a period of 1 to 12 hours. cosmetic process

Préparation des phases A et B

[0172] The ingredients of phase A and the pigments of phase B were weighed in a large stainless steel bowl.

[0173] Phase A was ground in a robot cutter: 1 time for 15 seconds at 1500 rpm and then 3 times for 1 minute at 3000 rpm. 2. Incorporation of phase C:

[0174] The ingredients of phase C (excluding isododecane) were heated (in a water bath at 75°C). When phase C was melted, it was stirred using a deflocculator until a vortex formed (approximately 300 rpm) and then introduced under stirring via the lid of the food processor: once a minute at 1500 rpm.

[0175] The whole was ground in the Robot-coupe: 1 time 1 minute at 1500rpm, then 2 times 2 minutes at 3000rpm and 1 time 1 minute at 3000rpm. 3. Preparation of the slurry:

[0176] The previously obtained mixture was diluted in a large quantity of isododecane to obtain the desired viscosity of the "powder / solvent" mixture. This paste was injected from the bottom (back injection) into the cups using a Pilot Back Injection machine sold by NANYO CO.LTD. 4. Mud injection:

[0177] The back injection machine allowed the powder-solvent mixture, or slurry, to be injected from the bottom of the cup while simultaneously aspirating some of the dilution solvent. Throughout the injection process, the injection mold was kept under vacuum to allow the removal of isododecane, which was aspirated and collected in the vacuum trap. This vacuum facilitated the filling and homogenization of the cup.

[0178] The bottom-injected parts were then placed in a ventilated oven at 45°C until their weight stabilized. The product was then considered dry.

[0179] Example: the and Id obtained by a conventional dry process (outside the scope of this invention)

[0180] The compositions of examples le and Id, identical to compositions la and 1b without isododecane, were prepared in the following manner:

[0181] Protocol for preparing compositions le and Id by conventional dry process 1. Preparation of phases A and B

[0182] The ingredients of phase A and the pigments of phase B were weighed in a large stainless steel bowl.

[0183] Phase A was ground in a robot cutter: 1 time for 15 seconds at 1500 rpm and then 3 times for 1 minute at 3000 rpm. 2. Incorporation of phase C:

[0184] The ingredients of phase C, excluding isododecane, were heated in a bain-marie at 75°C. When phase C was melted, it was stirred using a deflocculator until a vortex formed (approximately 300 rpm) and then introduced under agitation via the lid of the robot-cutter: 1 time per minute at 1500 rpm.

[0185] The whole was ground in the Robot-coupe: 1 time 1 minute at 1500rpm, then 2 times 2 minutes at 3000rpm and 1 time 1 minute at 3000rpm.

[0186] 3. Compacting the powder by traditional press:

[0187] The bulk mixture was loaded, respecting a determined weight, into a container, which was itself placed in a support of the same dimensions. A fabric was placed on its surface, followed by an impression the same dimensions as the container. The assembly, thus installed, was pressed at a pressure of 40 kgf / cm² to form an eyeshadow in the form of a compacted powder.

[0188] This allowed us to obtain the examples le (composition la with a classic pressing) and composition Id (composition 1b with a classic pressing). Impact resistance measurement: Principle of measurement

[0189] The device for performing such a measurement, called the Machine per l'imballaggio - Drop test, sold by the company Co Pack (ITALY), made it possible to perform drop tests on solid compositions in compact powder form to measure their impact resistance. The drop height was 30 cm. Using a ruler, the size of the support holding the compact (according to the size of the container) was fixed, and then the compact was dropped using compressed air, which actuated the opening of the support. The number of drops required to break up the powder was measured.

[0190] The test was carried out on 5 cups. The drop test was considered satisfactory when the average number of drops was greater than or equal to 10. Measurement of pick-up / pay-off at the foam applicator

[0191] EQUIPMENT - Caressa® foam applicator (refl001486 - Kahn) - Supplale Support (manufacturer IDEMISTUPETROCHEMICAL, composition: collagen sheet with artificial relief glued onto a fabric) - powder sample already used at least once and not visually damaged - heated plate (ref PCMF400x600 - EKIUM). Principle of measurement

[0192] A piece of supplale is placed on the heating plate to temper it to 32°C. The product is taken up by making 3 transverse movements while holding the applicator parallel to the surface of the powder and perpendicular to the direction of movement.

[0193] Next, the product was applied to the supplale by making three transverse movements while holding the applicator parallel to the surface of the supplale and perpendicular to the direction of movement. The application area was approximately 3.5 cm in length and width of the applicator.

[0194] The result obtained was then noted on a scale of 0 to 5 according to the intensity relative to pre-established limits. 5 is equivalent to very good 4 is equivalent to good 3 is equivalent to medium 2 is equivalent to mediocre 1 is equivalent to low 0 is equivalent to impossible.

[0195] A difference of 1 is considered significant. Pick-up / pay-off measurement with a brush

[0203] A difference of 1 is considered significant. Assessment of Matity

[0204] A protocol for evaluating mattifying the product was implemented on a panel of 10 experienced individuals. Mattifying the product was evaluated in bulk while it was in its container, and then on the skin after application.

[0205] The panel gives a score from 0 to 5. 0 corresponds to a shiny powder. 5 corresponds to a matte powder. Sensory Assessment

[0206] An evaluation protocol was implemented on a panel of 10 experienced individuals, and the result concerning: - the texture of the powder, - the sensory experience, and in particular the softness to the touch, the creaminess, the smoothness when scooping, - the application (quantity taken, ease of application, adhesion to the application), - the makeup result: uniformity, powdery effect, coverage, colour effect, matte finish, comfort throughout the day, hold and ease of removal of a composition according to the invention evaluated by the same persons. Results

[0207] The panel gives a score from 0 to 10. 0 corresponds to a powder that does not meet any of the above parameters. 10 corresponds to a powder satisfying all the above parameters.

[0208] The results of the comparative tests are shown in the table below:
