Description

Title of the invention: DRY COMPOSITION CAPABLE OF BEING PRESSED, AND ITS USES technical field

[0001] The present invention relates to a dry composition capable of being pressed, to a method of preparing a cosmetic composition, as well as to the cosmetic composition and its use.

[0002] The present invention finds applications particularly in the field of cosmetics, especially in hygiene and care of the skin and / or mucous membranes and / or hair.

[0003] In the description below, references in brackets ([ ]) refer to the list of references presented at the end of the text. State of the art

[0004] Makeup removers are personal hygiene products used daily, or even twice daily, because they allow the removal of impurities and traces of makeup present on the skin and eyes.

[0005] Makeup removers are generally packaged in bottles, possibly with a pump, or in other containers. They are usually in the form of milk, lotion, micellar water, or even oil. Apart from oil, these products are mostly water-based.

[0006] However, environmental concerns are becoming increasingly important in the cosmetics industry. Therefore, for ecological reasons, efforts are currently underway to reduce the amount of water in these types of cosmetic products, both to decrease the amount of water transported and to reduce the amount of packaging.

[0007] Thus, one of the ways to reduce the amount of water in cosmetic products is to formulate them in solid and / or dry form, to be diluted or reconstituted by the consumer at home to obtain the finished product.

[0008] Generally speaking, the limitation of these products lies in their appearance after dilution. Indeed, the texture of the finished product is often different from the texture of an equivalent conventional product. Furthermore, the sensory experience of the product is often inferior to that of an equivalent conventional product.

[0009] Thus, there remains a strong demand for products in dry form, making it possible to reduce the quantities of single-use plastic and water used during packaging and transport, while retaining the sensory properties of a classic makeup remover product and respecting good eco-design.

[0010] Description of the invention

[0011] The present invention is specifically designed to address these needs and drawbacks of the prior art.

[0012] The inventors of the present product have indeed developed a solid or dry product which, when reconstituted by the consumer by adding water at a temperature between approximately 15°C and 50°C, presents a wide range of textures, including innovative textures, as well as sensory properties as satisfactory as conventional products.

[0013] In particular, the inventors have succeeded in developing, from a mixture in the form of powders or granules, and after reconstitution with water, a cosmetic composition having a texture that allows it to be spread on the skin. The inventors have also developed, from this mixture of powders or granules, a compact solid form that is sufficiently solid to be transported while remaining soluble enough to transform into a cosmetic composition having a texture that allows it to be spread on the skin after the addition of water.

[0014] The galenic formulation developed by the inventors also offers the following advantages: - A wide range of dosage forms once the final product is reconstituted by adding water, including a gel texture, a foamy gel texture, a white opaque gel resembling milk, and a syrupy, honey-like texture, likely to satisfy a wide range of consumers, - Industrialization facilitated by improved flow of ingredients, particularly in powder or granule form, and reduced stickiness during compaction, - improved sensory experience compared to micellar water during makeup removal, providing greater glide and comfort. - Removal of makeup products, even waterproof, from the face, eyes and lips, to be used with or without rinsing, - greater respect for the environment by not transporting water to the store, - a reduction in shelf space in stores. Thus, a first object of the invention relates to a dry composition capable of being pressed, comprising: - at least one polyol in powder form, - at least one surfactant, - at least one powdered gelling agent, - optionally, at least one internal lubricator, - optionally, at least one preservative, - optionally, at least one buffering and pH regulating agent, - optionally, at least one fragrance, said dry composition capable of being pressed having flow properties corresponding to a Carr index less than or equal to 25 and a Hausner ratio less than or equal to 1.34.

[0015] For the purposes of this invention, "dry composition" means a composition that is free of water and uncompacted, i.e., before the compaction step. Because the composition is uncompacted, it possesses the flow properties defined above and is therefore distinct from a solid product. As such, the dry composition can be in any suitable form, such as a powder or granules.

[0016] For the purposes of this invention, "polyol" means any organic compound comprising at least one hydroxyl group (-OH), provided that the compound is in powder form. Advantageously, within the scope of this invention, polyols allow the dry composition to be pressed into a compact tablet that is sufficiently solid for transport, while remaining soluble to give the reconstituted product, after the addition of water, a dosage form that may be a gel texture, such as micellar jelly, a foamy gel texture, a white opaque gel resembling milk, or a syrupy texture like honey. These may include, for example, polyols of the glycitol class. At least one polyol may be selected from erythritol, sorbitol, and mannitol. Advantageously, the composition may include erythritol and sorbitol as polyols.Advantageously, the concentration of at least one polyol in the dry composition can be chosen to obtain the aforementioned technical effect, depending on the other components of the composition. In particular, the concentration can be between 1 and 90% by weight relative to the total weight of said composition, for example between 10 and 80%, or between 20 and 70%, or between 30 and 50%, or between 40 and 45%.

[0017] For the purposes of this invention, "surfactant" means any compound that modifies the surface tension between two surfaces. This compound may be in the form of a powder, a liquid, or a solid that can be ground into a powder before being mixed with the other ingredients of the dry composition. It is preferably in powder form. Regardless of its form, the surfactant can be mixed with the other ingredients, namely the polyol and the gelling agent, and optionally any additional ingredients, despite its flow characteristics at the time of mixing. The surfactant may, if necessary, be ground or granulated before mixing to obtain a dry composition exhibiting the aforementioned flow properties, namely a Carr index of 25 or less and a Hausner ratio of 1.34 or less. Advantageously, within the scope of the invention, the surfactant allows for the cleansing and / or removal of makeup from the skin and / or hair by forming micelles, even in the case of waterproof makeup, despite a low concentration of surfactants in the composition of the invention. At least one surfactant can be selected from among cocamidopropyl betaine, sodium cocoyl glutamate, sodium methyl cocoyl taurate, sodium cocoyl glycinate, and sodium cocoyl isethionate. Advantageously, the concentration of at least one surfactant in the dry composition can be chosen to achieve the aforementioned technical effect, depending on the other components of the composition.In particular, the concentration may be between 0.0001 and 45% by weight relative to the total weight of said dry composition, particularly when the reconstituted cosmetic composition is a rinse-off product, or between 0.0001 and 10%, particularly when the reconstituted cosmetic composition is a leave-on product, for example between 0.10 and 9.0%, or between 0.10 and 8.8%, or between 0.20 and 7.0%, or between 0.30 and 5.0%, or between 0.40 and 4.5%, or between 7.0 and 8.8%.

[0018] For the purposes of this invention, "gelling agent" means any compound that gives a preparation a gel-like consistency, provided that this compound is in powder form. Advantageously, within the scope of the invention, the flow and compression properties of the gelling agent reduce the stickiness imparted by polyols and surfactants so that the dry composition flows in a manner suitable for industrial production during ingredient mixing, and prevents it from sticking to instruments during compaction. Furthermore, advantageously, the gelling agent can prevent the formula from becoming soapy. Advantageously, the concentration of at least one gelling agent in the dry composition can be chosen to obtain the aforementioned technical effect, depending on the other components of the composition.In particular, the concentration may be between 1 and 90% by weight relative to the total weight of said composition, for example between 10 and 80%, or between 20 and 70%, or between 30 and 50%, or between 40 and 45%.

[0019] After mixing the aforementioned ingredients, and optionally the optional ingredients, the dry composition suitable for pressing exhibits flow properties corresponding to a Carr index less than or equal to 25 and a Hausner ratio less than or equal to 1.34. This can be obtained by simply mixing the various ingredients, possibly with the optional ingredients, or by carrying out one or more granulation steps of all or part of the ingredients, before or after their mixing, separately or together. Thus, the dry composition according to the invention can be in the form of a powder or granules.

[0020] The Carr index can be measured by any means known to a person skilled in the art, for example with a GranuPack® (Granutools) according to the procedure described in Assia Saker's thesis, "Critical Study of Some Experimental Techniques for Evaluating the..." Powder flowability. Process engineering. University of Lorraine, 2018. French. ffNNT: 2018LORR0314ff. fftel-02130382 ([1]) using the following formula: Carr index = ptassee

[0021] The Hausner ratio can be calculated by any means known to a person skilled in the art, for example with a GranuPack® (Granutools) according to the procedure described in the thesis of Assia Saker ([1]), using the following formula: Hausner ratio =

[0022] The Carr index and the Hausner ratio are parameters commonly used by persons skilled in the art to evaluate the flowability of a substance, according to the table below, taken from the thesis of Assia Saker ([1]):

[0023] [Tables 1] Flowability Hausner Ratio Carr Index (%) Excellent, free flow 1.00-1.11 <10 Good 1.12-1.18 11-15 Fair 1.19-1.25 16-20 Passable 1.26-1.34 21-25 Poor, cohesive powder 1.35-1.45 26-31 Very poor 1.46-1.59 32-37 Very poor >1.60 >38

[0024] At least one gelling agent may, for example, be chosen from starches such as hydroxypropyl starch phosphate, distarch phosphate, sodium carboxymethyl starch, modified potato starch, rice starch such as Oryza sativa, or sodium hydroxypropyl starch phosphate, sclerotium gum, alginic derivatives such as alginic acid, sodium alginate or algin, xanthan gum, gum arabic, Sterculia urens gum, Chondrus crispus powder (carrageenan), gelane gum, guar gum, konjac such as konjac glucomannan, cellulose derivatives such as ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropyl methylcellulose or methylcellulose, cellulose, acacia senegal gum, gum of cyamopsis tetragonoloba (guar), tragacanth gum, acacia gum, glucomannan, galactomannan, and mannan.

[0025] For the purposes of this invention, "internal lubricant" means any compound that increases the internal sliding of the molecules of a mixture over one another. Advantageously, when present, the internal lubricant, by virtue of its combination with the other components and in the indicated proportions, allows to obtain a compact tablet that is sufficiently solid for transport, while remaining soluble enough to form a gel upon the addition of water. At least one internal lubricant may be selected from magnesium stearate, aluminum stearate, and zinc stearate. Advantageously, the concentration of at least one internal lubricant in the dry composition may be chosen to achieve the aforementioned technical effect, depending on the other components of the dry composition. In particular, when present, the concentration may be between 0.0001% and 5.0% by weight relative to the total weight of said composition.

[0026] Advantageously, at least one buffering and pH-regulating agent, when present, allows the pH of the reconstituted product to be controlled for use and storage for 6 months in the bathroom, at values ​​between 0 and 5% by weight relative to the total weight of said composition, for example, between 0.1 and 4.5%, or between 0.5 and 4.0%, or between 0.7 and 3.0%. The buffering agent may, for example, be chosen from citric acid and sodium citrate. Advantageously, the concentration of at least one buffering agent in the dry composition may be chosen to obtain the aforementioned technical effect, depending on the other components of the composition. In particular, the concentration may be between 0 and 2.0% by weight relative to the total weight of said composition, for example, approximately 1.0%.

[0027] Advantageously, at least one preservative, when present, increases the microbiological and / or chemical stability of the dry composition and / or the compressed solid product and / or the cosmetic composition once reconstituted. At least one preservative may be selected, for example, from sodium benzoate, potassium sorbate, sorbic acid, and sodium dehydroacetate. For example, the composition may include sodium benzoate and potassium sorbate as preservatives. Advantageously, the concentration of at least one preservative in the dry composition may be selected to achieve the aforementioned technical effect, depending on the other components of the composition. In particular, when present, the concentration may be between 4.2 and 6.0% by weight relative to the total weight of said composition, for example, between 4.4 and 6.0%, or between approximately 4.4 and 5.5%.

[0028] Advantageously, the at least one fragrance can be any fragrant material with olfactory characteristics compatible with use in cosmetics, of natural and / or synthetic origin. It can thus impart a pleasant scent to the cosmetic composition once it has been reconstituted. It can also improve the shaping and / or compaction of the dry composition by binding the powders to obtain a solid product and / or prevent the solid product from crumbling. Since the fragrance can be solubilized in a solvent for perfumery raw materials, a granulation step is carried out before or after mixing with the Other ingredients. The fragrance may be any fragrance known to those skilled in the art, for example, honey, aloe vera, vanilla, floral, coconut, or exotic fruit; this list is not exhaustive. Depending on whether or not it is present in the dry composition, the fragrance concentration may range from 0% (not included if the fragrance is not present) to 7% by weight relative to the total weight of said composition, for example, between 0.0001% and 5.0%, or between approximately 0.0001% and 2.5%.

[0029] Advantageously, at least one disintegrating agent can be any ingredient that accelerates the reconstitution time of the dry composition in water, compared to the same dry composition without the disintegrating agent. The time saving can be approximately at least 10%, or at least 20%, or at least 30%, or at least 40%, or at least 50%, or at least 60%, compared to the time required for reconstitution of the same dry composition without the disintegrating agent. This may include, for example, at least one disintegrating agent chosen from citric acid, a combination of citric acid and monosodium citrate, a combination of citric acid, monosodium citrate, sodium bicarbonate and gum arabic, guar gum, sodium bicarbonate, a combination of sodium bicarbonate and gum arabic, croscarmellose sodium, sodium starch glycolate and polyplasdone crospovidone.Depending on whether or not it is present in the dry composition, the concentration of the disintegrating agent can be between 0 (not included if the disintegrating agent is not present) and 5% by weight relative to the total weight of said composition, for example between 0.0001 and 5.0%, or between 0.3 and 4.5%, or between 0.5 and 4.0%, or between approximately 0.5 and 2.0%.

[0030] Advantageously, the dry composition can be obtained by mixing the different ingredients. As previously stated, the process for preparing this composition may further include one or more granulation steps of all or part of the ingredients, before or after their mixing, separately or together. Particle granulation consists of increasing the size of the particles in order to obtain agglomerates. Traditional reasons for granulating a material include improving flow and storage properties, increasing the intrinsic density of the particles, reducing dust formation, or decreasing material segregation. Thus, the granulation step can allow for better flow of the powders, separately or together. The granulation step can be carried out by any method and means known to those skilled in the art, for example, by means of a granulator.The granulation stage(s) take place before or after the compaction stage. Thus, the mixture responds favorably to the compression method. Advantageously, the ingredients and their varying concentrations in the dry composition allow for a flow rate suitable for industrial implementation, possibly after one or more granulation stages. granulation can be carried out using dry and / or wet methods. The granulation step can be performed by any method and means known to those skilled in the art, such as those described in Amal TITA-GOLDSTEIN's thesis, "Shaping Powders by Compression: Influence of Process and Formulation on Controlling In-Use Properties." Thesis, 2013 ([2]). For example, when granulation is performed using powders, it can be carried out using a roller compactor combined with grinding or a tablet press combined with grinding. Alternatively, when granulation is carried out from a mixture of powder and liquid, it can be carried out by means of a vertical granulating mixer and drying, a horizontal granulating mixer and drying, a twin-screw extrusion and drying, an oscillating or centrifugal granulator and drying, or a fluidized bed.In the preparation of the dry composition, the granulation step(s) take place before the compaction step.

[0031] Optionally, the composition may include ingredients not mentioned above, in order to improve properties already stated, or to obtain new ones. For example, bicarbonate and / or citric acid may be included to obtain effervescent properties of the cosmetic composition once it has been reconstituted.

[0032] A second object of the invention relates to a solid product obtained by pressing (also called compacting or compressing) the dry composition as defined above. The composition can be pressed by any suitable means, either directly onto the composition in powder form or after one or more granulation steps. The pressing can be carried out by any means known to those skilled in the art, for example, using a tablet press. Optionally, a granulation step can be performed after the compaction step to obtain a solid product in the form of granules. The shape and size of the solid product can be chosen according to requirements, for example, tablets, granules, beads, or sticks. The thickness and / or circumference of the product can, for example, be between 0.5 cm and 5 cm, and its surface area can, for example, be between 1 cm² and 20 cm².Advantageously, the solid product of the invention may have sufficient hardness or mechanical strength to prevent breakage during handling or subsequent production steps, or to avoid being too brittle for transport. The hardness of a solid product can be determined by any method known to those skilled in the art, such as measuring the intensity of the force applied diametrically to it to cause its rupture by crushing, or calculating the tensile strength of the product according to the recommendations of the United States Pharmacopeia Convention (USP 1217, May 1, 2012, pp. 868-870 [3]). Advantageously, the in. The ingredients and their varying concentrations in the dry composition prevent them from sticking to the equipment during compression, thus enabling optimized industrial implementation of the compression process while producing a compact product that is sufficiently robust for transport. Advantageously, the solid product is in tablet form.

[0033] Another object of the invention relates to a method for preparing a cosmetic composition, comprising diluting the solid product or the dry composition as defined above in 1 to 50 times its weight in water, for example, in 10 to 50 times, or in 20 to 40 times. The dilution can be carried out in water, with or without stirring. Advantageously, this can be done by the consumer by placing the solid product in a container designed for this purpose, adding water at a temperature between approximately 15°C and 50°C directly to the solid product or the dry composition, and then optionally shaking the container. Optionally, a dissolution time may be necessary to ensure complete dilution. The water can be any water suitable for cosmetic, skincare, or personal hygiene use.This could include tap water, purified water, floral water, spring water, thermal water, seawater, or mineral water.

[0034] Another object of the invention relates to a cosmetic composition comprising from 1 to 50% by weight of a solid product or a solid composition as defined above, and from 50 to 99% by weight of water, relative to the total weight of said composition. The cosmetic composition is a textured composition, that is to say, one that has a texture different from that of water, which may be, as indicated above, a gel texture, for example, a micellar jelly, a foamy gel texture, a white opaque gel resembling milk, or a syrupy texture like honey. Optionally, the cosmetic composition may be effervescent if the composition in powder form contains ingredients that enable effervescence once the cosmetic composition is reconstituted.For example, the cosmetic composition may have a texture adapted to a chosen use such as shower gel, facial cleansing gel, facial makeup remover gel, shampoo, and hand wash gel.

[0035] Another object of the invention relates to the use of the cosmetic composition for cleansing and / or removing makeup from the skin, mucous membranes, and / or hair. For example, the use may be in a form chosen from that of a shower gel, a body wash, particularly for the face and / or lips, a facial makeup remover, a shampoo, and a hand wash. Advantageously, it may be used with or without rinsing.

[0036] Other advantages may also become apparent to a person skilled in the art upon reading the Examples below are given for illustrative purposes.

[0039] The powders shown in Tables 2 to 7 are mixed to obtain the composition in powder form. The composition is then optionally compacted to obtain a tablet. Finally, water is added to the tablet, or directly to the powder or granules if there has been no compaction, to reconstitute the textured cosmetic composition in the form of a micellar gel.
