Description

Title of the invention: COLOURED SKIN COMPOSITIONS CONTAINING BIS-ETHYLHEXYLOXYPHENOL METHOXYPHENYL TRIAZINE AND A COLORING AGENT FIELD OF INVENTION

[0001] This disclosure relates to skin colour compositions comprising 2,4-bis-{[4-(2-ethylhexyloxy)-2-hydroxy]-phenyl}-6-(4-methoxyphenyl)-1,3,5-triazine (INCI name: bis-ethylhexyloxyphenol me-thoxyphenyl triazine) and at least one colouring agent, as well as processes for manufacturing and using such compositions. DISCUSSION OF THE CONTEXT

[0002] Radiation with wavelengths between 290 nm and 400 nm allows the human epidermis to tan, while radiation with wavelengths between 290 and 320 nm, called UVB rays, hinders the development of a natural tan. Exposure is also likely to cause a detrimental alteration of the biomechanical properties of the epidermis, resulting in the appearance of wrinkles leading to premature skin aging (i.e., photoaging).

[0003] UVA rays with a wavelength between 320 and 400 nm penetrate the skin more deeply than UVB rays. UVA rays cause immediate and persistent tanning of the skin. Daily exposure to UVA rays, even for a short period under normal conditions, can damage collagen and elastin fibers, resulting in changes in the skin's microrelief, the appearance of wrinkles, and uneven pigmentation (spots, uneven skin tone).

[0004] Numerous studies show the need for effective protection against UVA and UVB to prevent sunburn, photoaging, and the like.

[0005] In order to obtain a high protection product, it is generally necessary to combine a large number of sunscreens and / or a large quantity of UV filters to achieve high levels of filtration efficiency.

[0006] However, high levels of UV filters do not lend themselves to the easy development of compositions with a stabilized and pleasant texture.

[0007] In certain makeup products, it is also desirable to offer UV protection in addition to a coloring or optical effect when applied to the skin. Colored skin compositions may include mineral UV filters, such as titanium dioxide or zinc oxide, in order to obtain a They offer UV protection; however, mineral UV filters impart a white cast when applied to the skin and significantly impact the ability to achieve a wide range of shades (colors) or optical effects. Colored skin compositions may also utilize organic UV filters, such as octocrylene, octinoxate, and avobenzone; however, organic UV filters often leave an unpleasant, greasy texture when applied to the skin.

[0008] There remains in art a need for improved skin colour compositions which offer UV protection efficacy and a wide range of shades (colours) or optical effects without having a greasy and unpleasant texture.

[0009] Therefore, one aspect of the present disclosure is a skin colour composition which has UV protection and good colour stability in light without a greasy and unpleasant texture. Summary of the invention

[0010] This disclosure relates to skin colour compositions comprising at least one colouring agent and bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT or bemotrizinol). Preferably, the bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is present in the compositions in an amount effective in improving the photostability of the colouring agent.

[0011] This disclosure also relates to processes for treating, caring for, protecting, improving the appearance and / or making up the skin, including the application of skin colour compositions of this disclosure to the skin in sufficient quantity to treat the skin, care for it, improve its appearance and / or make it up.

[0012] This disclosure also relates to methods for improving the photostability of the coloring agent in skin colour compositions comprising at least one coloring agent, the methods comprising the addition of bis-ethylhexyloxyphenol methoxyphenyl triazine to the compositions during the formation of the compositions in an amount sufficient to improve the photostability of at least one coloring agent.

[0013] This disclosure also relates to processes for manufacturing skin-colored compositions comprising combining bis-ethylhexyloxyphenol methoxyphenyl triazine and at least one coloring agent in the compositions during composition formation. Preferably, bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) is added to the compositions in an amount effective in improving the color photostability of at least one coloring agent.

[0014] This disclosure also relates to methods for improving the color intensity stability and / or color shade stability in light of skin colour compositions comprising at least one colouring agent, the methods including the addition of bis-ethylhexyloxyphenol methoxyphenyl triazine (BEMT) to the skin colour compositions during the formation of the compositions in an amount sufficient to improve the color intensity stability and / or color shade stability of the compositions in light.

[0015] It must be understood that both the preceding general description and the des The detailed description that follows is only exemplary and explanatory and does not limit disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0016] In the following description and the claims annexed thereto, it shall be understood that the terms used have their ordinary and usual meanings in the art, unless otherwise specified.

[0017] “Approximately” as used here means to within 10% of the number indicated (for example "approximately 10%" means from 9% to 11% and "approximately 2%" means from 1.8% to 2.2%.

[0018] “A” or “an” as used here means “at least one”

[0023] “Non-volatile”, as used here, means having a flash point greater than approximately 115 °C.

[0024] “Polymer” as used herein means a compound that is made up of at least two monomers.

[0025] “Exempt” or “substantially exempt” or “devoid of” as used herein This means that although it is preferable for no quantity of the specific component to be present in the composition, it is possible for very small quantities of it to be present in the compositions of the disclosure, provided that these quantities do not materially affect at least one, preferably most, of the advantageous properties of the compositions of the disclosure. Thus, for example, "oil-free" means that an effective quantity (i.e., greater than trace amounts) of oil(s) is omitted from the composition (i.e., about 0% by weight), "substantially oil-free" means that oil(s) is / are present in quantities not exceeding 0.1% by weight, and "oil-free" means that oil(s) is / are present in quantities not exceeding 0.25% by weight, relative to the total weight of the composition.The same nomenclature applies to all other ingredients identified throughout the application and in this paragraph, such as, for example, specific UV filters and / or surfactants (the compositions in the disclosure that are "free of oxybenzone and / or octinoxate," "substantially free of oxybenzone and / or octinoxate," and "devoid of oxybenzone and / or octinoxate," as well as "free of surfactants," "substantially free of surfactants," and "devoid of surfactants" have meanings consistent with the discussion in this paragraph), even if they are not specifically mentioned for each identified ingredient. The examples of the use of such language, such as those in this paragraph, are intended to be provided by way of example, not limitation.

[0026] “UV Filters” as used herein means approved sunscreen active agents by a government regulatory agency such as the Food and Drug Administration (FDA) in the United States or the European Commission in Europe and includes avobenzone, octocrylene, benzophenones, benzotriazoles and merocyanines, as well as mineral UV filters such as zinc oxide (ZnO) and titanium dioxide (TiO2).

[0027] “Anhydrous” as used here means that the compositions of the disclosure contain less than 3% water, which means that the compositions can also contain less than 2% water, and less than 1% water, as well as be "free of water", "substantially free of water" and "devoid of water", as defined above.

[0028] “Skin” as used herein means the nails (fingernails and / or toenails), the skin such as that of the body, face and around the eyes, scalp and mucous membranes such as the lips.

[0029] “Physiologically acceptable” means compatible with the skin and exhibiting a pleasant colour, smell and feel, and does not cause unacceptable discomfort (tingling or pulling) that would discourage a consumer from using the composition.

[0030] “UV protection efficiency” or “filtration efficiency” in the context of the this disclosure is evaluated from one or more elements among FPS, FPUVA, critical wavelength and UVA-I / UV ratio.

[0031] The "SPF" (Sun Protection Factor) measures the level of protection against erythema provided by a composition. The SPF value corresponds to the ratio between the minimum erythematous dose (MED) measured on skin covered with the composition and the MED measured on bare skin. The term "SPF" is known in the art of sunscreens and is defined, for example, in "A new substrate to measure sunscreen protection factors throughout the ultraviolet spectrum," J. Soc. Cosmet. Chem., 40, 127-133 (May / June 1989).

[0032] The evaluation of the SPF (Sun Protection Factor) can be carried out, for example, in vitro with a spectrophotometer from Labsphere (North Sutton, NH, USA). In such an evaluation, the plate is the material onto which the composition under test is applied. Polymethyl methacrylate (PMMA) plates can be used for such an evaluation. An example of an acceptable protocol is currently undergoing ISO accreditation under the name ISO Committee Draft 23675.

[0033] The evaluation of the sun protection factor (SPF) can also be performed in vivo in accordance with ISO 24444:2019 “Cosmetics-Sun protection test methods-In-vivo determination of the sun protection factor (SPF).” It can also be determined in accordance with FDA protocols, as described in the document “Labeling and Effectiveness Testing; Sunscreen Drug Products for Over-the-Counter Human Use” published in the US Federal Register on 07 / 05 / 2011 (https: / / www.federalregister.gov / d / 2011-14766); 21 CFR Part 352 Subpart D § 352.72, updated and revised by the 2011 publication in the Federal Register.

[0034] “UVA protection factor” refers to a characteristic index assessing the UVA protection provided by a composition. For example, the UPFAP index can be measured in vivo according to the "PPD" (Persistent Pigment Darkening) method of the ISO-24442:2022 protocol, measuring the skin color observed 2 to 4 hours after exposure to UVA. It can also be determined in accordance with FDA protocols, as described again in 21 CFR Part 352 Subpart D § 352.72 as mentioned above in relation to the SPF.

[0035] UVA protection can also be assessed in vitro using the Labsphere® spectrophotometer under conditions such as those mentioned above in relation to the SPF. ISO 24443:2021 describes such an in vitro procedure.

[0036] FDA broad-spectrum test procedures, particularly "critical wavelength" test procedures, are also available in 21 CFR Part 352 Subpart D § 352.72. In addition, broad-spectrum test procedures include the determination of the UVA1 / UV ratio as described in "Sunscreen Drug Products for Over-the-Counter-Human-Use" published in the Federal Register https: / / www.federalregister.gov / documents / 2019 / 02 / 26 / 2019-03019 / sunscreen-drug-products-for-over-the-counter-human-use. "In the assay described in the monograph, known as the Boots adaptation of the Diffey / Robson test method, a ratio is generated between the protection offered by the sunscreen product against UVA1 (340-400 nm) and the protection against total UV radiation (UVB and UVA at 290-400 nm) calculated from the absorbance curve. This UVA1 / UV ratio would represent the product's score in the in vitro test."

[0037] According to this disclosure, the compositions in this disclosure preferably have one or more of the following properties:

[0038] The compositions have a critical wavelength, as determined by FDA critical wavelength procedures, of at least 370 nm;

[0039] The compositions have an FPS value of at least 15, preferably at least 30, preferably at least 50 and preferably at least 70;

[0040] The compositions have an FPUVA / FPS ratio of at least 1 / 3, and preferably of at least 2 / 5 and / or

[0041] The compositions have a UVA1 / UV ratio of 0.7 or more, preferably 0.75 or more, and preferably 0.8 or more.

[0042] The "makeup result" as used herein refers to the visual impact of a composition when applied to a keratinous material such as the skin. The makeup result may relate to the apparent color of the product after application to a keratinous material or to an optical effect such as shine, the blurring of fine lines and imperfections, or a concealing effect on pores or defects after application of the product to the keratinous material.

[0043] “Long-lasting” as used herein refers to compositions where the colour or other apparent properties remain the same or substantially the same as at the time of application, as seen with the naked eye, after a prolonged period or After a specific stress event, such as immersion in water or friction, "longevity" can be assessed by evaluating longevity properties using any method known in the art for evaluating such properties. For example, longevity can be assessed by a test involving the application of a composition to a keratinous material such as skin and evaluating the color of the composition after an extended period. For instance, the color of a composition can be evaluated immediately after application to a keratinous material such as skin, and these characteristics can then be re-evaluated and compared after a certain time. Furthermore, these characteristics can be evaluated against other compositions, such as commercially available ones.Longevity can also be assessed using in vitro processes on non-keratinous substrates such as polymethyl methacrylate (PMMA), in which properties such as colour, transparency or in vitro FPS can be evaluated before and after a period or stress factor such as immersion in water, incubation at high temperatures or the application of an abrasive technique.

[0044] “Natural” as in the expression “natural compound” means any compound derived directly from a natural substance such as a plant without having undergone chemical modification.

[0045] “Compound of natural origin” means any compound derived from a natural compound which has undergone one or more chemical modifications, for example by organic synthesis reaction, without the properties of the natural compound having been modified.

[0046] “Synthetic compound” means any compound that is neither a natural compound nor a composed of natural origin.

[0047] “Room temperature” means approximately 20 to 25 °C.

[0048] “Atmospheric pressure” means 760 mmHg, that is about 105 pascals.

[0049] “UV filter” and “sunscreen agent” are used interchangeably in the present request.

[0050] The expressions "UV effectiveness", "UV protection" and "UV effectiveness" are used interchangeably in this application.

[0051] The compositions and processes of this disclosure may include, consist of, or consist essentially of the essential elements and limitations of the disclosure described herein, together with any additional or optional ingredients, components, or limitations described herein or otherwise useful. For example, the UV (ultraviolet) absorbing system of the compositions of the disclosure may "consist essentially of" bis-ethylhexyloxyphenol methoxyphenyl triazine alone, or bis-ethylhexyloxyphenol methoxyphenyl triazine in combination with zinc, titanium, and / or cerium oxides, and / or optionally one or more organic UV filters.

[0052] Similarly, the color protection system against UV rays (“color protection system”) of the disclosure compositions may “consist essentially of” bis-ethylhexyloxyphenol methoxyphenyl triazine.

[0053] For the purposes of this disclosure, the "fundamental novel property" associated with the compositions, components, and processes that "consist essentially of" the identified ingredients or actions is "color intensity stability and color hue stability in light." The concept of "color intensity" and / or "color stability" includes the ability to achieve a wider color range and / or greater color intensity, partly due to improved stability.

[0054] “Color intensity stability” as used here means stability against the de Visible discoloration (fading) of the composition's color over time. Color intensity stability can be visually assessed by comparing the color intensity immediately after application of the color composition of this disclosure to the skin (i.e., within 5 minutes of application) with the color intensity of the composition on the skin after a predetermined time (e.g., 6 hours) after application. The color intensity stability of the skin-colored composition of this disclosure prior to application can also be visually assessed by comparing an initial determination of the color intensity (time = T0) with a determination at a later date after exposure of the composition to light for a predetermined time (e.g., 2 months) at a predetermined temperature (e.g., 25°C or 45°C).

[0055] “Color shade stability” as used here means stability against the Visible color change of the composition over time (e.g., from a reddish color to an orange color due to yellowing). Shade stability can be visually assessed using the same protocols discussed above regarding color intensity stability, either before or after application of the composition to the skin.

[0056] Color intensity stability or color shade stability can also be evaluated using a colorimeter or chromatometer such as a CR-400 or CR-410 chromatometer sold by Konica Minolta, designed to quantitatively measure the color of an object or substrate, or of a product applied to a substrate. The evaluation of color stability using a colorimeter or chromatometer is designed to quantitatively report color changes via a color evaluation system such as L*, a*, or b*. In such cases, color stability can be determined or reported as an overall color change, a change in an individual quantitative value (L*, a*, or b*), or a combination of color values.

[0057] The compositions of this disclosure may be in any suitable form for use as a personal care composition, such as a stick, paste, cream, anhydrous composition, emulsion (oil-in-water, water-in-oil, multiple emulsion such as oil-in-water-in-oil), including in nanoemulsion form, gel, liquid, solid, foam, spray, etc. These compositions may be used for any purpose in colored skin products such as, for example, foundation, lip balms, lipsticks, concealers, eyeshadows, pressed powders, etc.

[0058] Reference is made herein to trade names of materials including, but not limited to, materials such as polymers and optional components. The materials are not intended to be limited by the materials described and referenced by a particular trade name herein.Equivalent materials (for example, those obtained from a different source under a different name or catalogue (reference) number) to those referenced by a trade name may be substituted for and used in the processes described and claimed herein.

[0059] Unless otherwise stated, all percentages and ratios are calculated by weight. Unless otherwise stated, all percentages are calculated on the basis of the total weight of a composition. All component or composition levels refer to the active level of that component or composition and are understood to exclude impurities, for example, residual solvents or by-products, which may be present in commercially available sources.

[0060] All US patents or patent applications disclosed herein are expressly incorporated by reference in their entirety. COLOURED SKIN COMPOSITIONS Coloring agent

[0141] A person skilled in the art shall ensure that the optional additional additives are chosen and / or their quantity so that the advantageous properties of the composition as disclosed are not, or are not substantially, compromised by the envisaged addition.

[0142] It goes without saying that the composition of the invention must be cosmetically or dermatologically acceptable, that is to say, it must contain a physiologically acceptable, non-toxic carrier. The composition may be in any pharmaceutical form normally used in the cosmetic and dermatological fields that is suitable for topical administration as indicated above.

[0143] These auxiliary additives may be present in the composition in a proportion of 0% to 99% (such as 0.01% to 90%) relative to the total weight of the composition and furthermore such as 0.1% to 50% by weight (where appropriate), including all intermediate ranges and sub-ranges. Examples of product shapes

[0144] As mentioned above, the skin colour compositions of this disclosure may be in any form suitable for use as a personal care composition, and may be used for any purpose associated with such skin colour products. Specific examples of products and forms of— Skin colour mulations include, but are not limited to, the following. 1. Sticks and solid compositions (e.g., solid lipsticks and foundation):

[0145] According to preferred embodiments, the compositions of this disclosure may be solid (for example, in stick form). "Solid" includes, in particular, a composition whose hardness can be measured using the "cheese wire" method. These compositions may contain little or no water (for example, be anhydrous, "free of," "substantially free of," "devoid of" water), contain little or no oil (for example, be "free of," "substantially free of," "devoid of" oil), be in the form of an emulsion (for example, an oil-in-water or water-in-oil emulsion), etc.

[0146] The hardness of a composition may, for example, be expressed in grams-force (gf). The composition of this disclosure may, for example, have a hardness ranging from 20 gf to 2000 gf, such as from 20 gf to 900 gf, and furthermore such as from 20 gf to 600 gf, including all intermediate ranges and sub-ranges.

[0147] The measurement of hardness can be illustrated by the following two examples. First, the "cheese-cutting wire" method noted above, which consists of cutting a composition into a stick 12.4 mm in diameter and measuring its hardness at 20 °C using a DFGHS 2 tensile testing machine from Indelco-Chatillon Co. or a similar machine at a speed of 100 mm / minute. The hardness value obtained by this method is expressed in grams as the shear force required to cut a stick under the above conditions. According to this method, the hardness of compositions according to this disclosure, which may be in stick form, may, for example, range from 120 gf to 270 gf, preferably from 170 gf to 220 gf, for a stick sample 12.4 mm in diameter.

[0148] If desired, another hardness test is carried out using a probe penetration method in the composition, in particular with a texture analyzer (for example, the Stable Micro Systems PLUS-UPGRADE texture analyzer equipped with a stainless steel cylinder 28 mm high and 2 mm in diameter). The hardness measurement can be carried out at 20 °C at the center of 5 samples of the composition. The cylinder is introduced into each composition sample at a preliminary speed of 2 mm / s, then at a speed of 0.5 mm / s, and finally at a post-speed of 10 mm / s, the total displacement being 2 mm. The recorded hardness value is that of the first maximum peak before the observed drops in value.

[0149] The hardness of the composition of such preferred embodiments is preferably such that the compositions are self-supporting and can easily disintegrate to form a satisfactory deposit on keratinous materials. Furthermore, this hardness can to provide good impact resistance to the compositions disclosed here, which can be molded or cast, for example, in stick or capsule form.

[0150] According to preferred embodiments, solid compositions (for example, sticks) can be prepared by incorporating any of the ingredients mentioned herein together with sufficient quantities of thickening agents to thicken the aqueous and / or oily phases of the compositions in order to make them "solid". These thickening agents are well known in the art and include, for example, oil-phase gelling agents, aqueous-phase gelling agents, waxes, thixotropic agents, fillers and the like, as well as mixtures of two or more of these ingredients. 1. Fluid compositions (e.g., liquid lipsticks, liquid foundation, nail polish):

[0151] According to preferred embodiments, the compositions of this disclosure may be fluid. "Fluid" specifically means a composition that is not solid at room temperature (25 °C) and whose viscosity can be measured. The term "fluid" means a liquid composition that flows under its own weight at room temperature (25 °C) and atmospheric pressure. Advantageously, a fluid composition according to this disclosure has a complex stiffness modulus G* of less than 1000 Pa, preferably less than 400 Pa, and preferably less than 200 Pa. Preferably, the composition has a viscosity at 25 °C of between 0.1 and 25 Pa·s, and preferably between 0.5 and 22 Pa·s.These compositions may contain little or no water (e.g., be anhydrous, "free of", "substantially free of", "devoid" of water), contain little or no oil (e.g., be "free of", "substantially free of", "devoid" of oil), be in the form of an emulsion (e.g., oil-in-water or water-in-oil emulsion), etc.

[0152] A suitable method for measuring viscosity is generally carried out at 25 °C, using a Rheomat RM 180 viscometer equipped with a No. 3 or No. 4 rod, depending on the work recommendations, the measurement being carried out after 10 minutes of rotation of the rod in the composition (after which a stabilization of the viscosity and the speed of rotation of the rod is observed), at a speed of 200 rpm.

[0153] According to preferred embodiments, fluid compositions can be prepared by incorporating any of the ingredients mentioned herein, including insufficient quantities of thickening agents to thicken the aqueous and / or oily phases of compositions so that they remain fluid and do not become "solid".

[0154] For nail compositions (e.g. nail polishes) in particular, suitable solvents may be present such as, for example, organic solvents that are liquid at room temperature like ketones such as me- ethyl ketone, methyl isobutyl ketone, diisobutyl ketone, isophorone, cyclohexanone or acetone; alcohols, such as ethanol, isopropanol, diacetonic alcohol, 2-butoxyethanol or cyclohexanol; glycols, such as ethylene glycol, propylene glycol, pentylene glycol or glycerol; propylene glycol ethers, such as propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate or dipropylene glycol mono(n-butyl) ether; short-chain esters (having a total of 2 to 7 carbon atoms), such as ethyl acetate, methyl acetate, propyl acetate, n-butyl acetate or isopentyl acetate; Alkanes, such as decane, heptane, dodecane, or cyclohexane; and mixtures thereof. Short-chain esters (having a total of 2 to 8 carbon atoms) are the most preferred. 1. Pastes (e.g., lip gloss)

The term "gel crossing point" (Sol / Gel point) means the point at which G" (loss modulus) intersects G' (storage modulus), expressed as a percentage of strain. This is the point at which a composition transitions from a mostly solid to a mostly liquid state. An example of a method for determining a gel crossing point is to use a TA Instruments Discovery HR-2 rheometer with a 40 mm parallel plate geometry on a flat stainless steel Peltier plate.The test can be performed at 25 °C with an angular frequency test parameter of 1.0 rad / s and a logarithmic sweep: % strain from 0.1 to 1000.0 %. 5 points per decade. 1. Foam

[0158] According to preferred embodiments, the compositions of this disclosure are in the form of a foam, that is, they comprise a gaseous phase dispersed in a condensed phase. "Foam" means a system comprising two or more phases in which a gas is dispersed into a condensed phase (liquid, gelled liquid, and / or solid) to form a foam structure. In some embodiments, the foam is a two-phase system having a gaseous phase dispersed in a liquid or gelled phase. The term foam is intended to exclude conventional sprays. By "conventional spray," we mean a system in which minute particles or droplets of liquid and / or solid are suspended in a gaseous phase. According to preferred embodiments, foam compositions can be prepared by incorporating any of the ingredients mentioned herein.

[0159] According to some embodiments, the foam, after being expelled from a container onto the palm of a user, will appear as an opaque mass of a certain visible thickness. If left undisturbed on the user's palm, the opaque mass can retain its shape and appearance, without substantial visible change, for a period ranging from approximately two seconds to several hours or more. According to some embodiments, the opaque mass can retain its shape and appearance for at least approximately 10 seconds. According to some other embodiments, the opaque mass can retain its shape and appearance for a period of at least one minute, such as at least two minutes, such as at least five minutes, such as at least ten minutes. During these periods, a substantial portion of bubbles or bubble cells may remain ("residual bubbles").The residual bubbles can be polydisperse or relatively monodisperse. According to some other embodiments, the foam may include at least a certain fraction of residual bubbles of dispersed gas ranging from about 0.25 mm to about 5 mm, such as from 0.5 mm to about 5 mm, such as from 1 mm to about 5 mm.

[0160] The size of the residual bubbles can be determined using, for example, a DFA100 foam analyzer (KRÜSS GmbH Wissenschaftliche Laborgerate). Approximately five grams of product can be dispensed into the glass tube of the foam analyzer. An image can be acquired using the camera integrated into the instrument one minute after the product has been dispensed.

[0162] According to preferred embodiments, compact powder compositions can be prepared by incorporating any of the ingredients mentioned herein. “Compact powder” means a mass of product whose cohesion is ensured at least partially by compaction or pressing during manufacturing. In particular, by taking a measurement using a TA.XT.plus texture analyzer sold by Stable Micro Systems, the compact powder according to this disclosure can advantageously have a compressive strength of between 0.1 and 2.5 kg, and in particular between 0.2 and 1.0 kg, relative to the surface area of ​​the spindle used. (in this case 7.07 mm2). The measurement of this resistance is carried out by moving a cylindrical pin with a flat head SMS P / 3 over a distance of 1.5 mm and at a speed of 0.5 mm / sec.

[0163] For preferred compact powders, the compositions preferably contain little or no water (e.g., anhydrous, "free of," "substantially free of," "devoid of" water). Preferably, these compact powders also contain a high solids content of 90% or more, preferably 95% or more, or preferably 97% or more. The "solids content" refers to the content of non-volatile matter and can be measured using a commercial halogen dryer, the Mettler Toledo "HR 73 Halogen Dryer." The measurement can be based on the weight loss of a sample dried by halogen heating and thus represents the percentage of residual material after the water and volatile matter have evaporated. This technique is described in detail in the machine documentation supplied by Mettler Toledo.

[0164] According to preferred embodiments, the compact powders in accordance with this disclosure preferably contain a powder phase in an amount greater than or equal to 35% by weight relative to the total weight of the composition, preferably greater than or equal to 40% by weight, preferably greater than or equal to 45% by weight.
