Description

Title of the invention: Solid skincare and / or makeup composition technical field

[0001] The present invention relates to the field of cosmetics. In particular, the invention relates to a solid cosmetic composition for the care and / or makeup of keratinous materials, in particular of the skin, eyelids, eyebrows or lips, and a cosmetic process implementing it. State of the art

[0002] In the field of cosmetics, consumers are increasingly looking for solid products, particularly anhydrous ones, for the care and / or makeup of the skin or lips.

[0003] Two properties are particularly valued, namely: (i) Coverage: Coverage refers to a cosmetic product's ability to conceal skin imperfections, such as blemishes, redness, or scars. A product with good coverage provides an even and smooth complexion, giving the skin a natural and flawless appearance; and (ii) Mechanical strength: Mechanical strength refers to a product's physical resistance as a solid. For example, a makeup stick such as a lipstick must be able to withstand pressure during application without breaking or deforming. Furthermore, it must maintain its shape and consistency despite variations in temperature and humidity. These mechanical properties are essential for ensuring ease of use and product longevity.

[0004] The coverage of a cosmetic product is achieved through the use of white pigments and / or fillers. Among the pigments widely used in cosmetics, titanium dioxide is a particularly noteworthy example. This inorganic pigment, used in powder form in numerous applications, is valued for its exceptional white color and its many other properties, such as its opacifying properties.

[0005] With the evolution of regulations, more and more studies are focusing on the safety of pigments for humans and the environment.

[0006] Although the use of titanium dioxide in products for topical application is not prohibited, manufacturers, particularly in cosmetics, are always looking for new compounds that can offer an alternative to the ubiquitous use of titanium dioxide that is suitable for use on the skin and hair.

[0007] In other words, manufacturers are looking for solutions to replace all or part of the titanium dioxide, particularly in existing formulations.

[0008] Prior art describes the use of other inorganic compounds, such as bismuth oxychloride or zinc oxide, to replace titanium dioxide in solid cosmetic compositions. However, the addition of these inorganic compounds intended to replace titanium dioxide tends to disrupt the balance of solidity, sensory properties, and coverage of the solid cosmetic compositions.

[0009] Furthermore, the necessary quantity of organic compounds to be added to solid cosmetic compositions in order to obtain a covering and opacifying power similar to that of titanium dioxide may lead to additional constraints and in particular to modifications of the shade of the cosmetic compositions.

[0010] There is therefore a need for an alternative solution to replace all or part of the titanium dioxide in solid cosmetic compositions while exhibiting satisfactory structural, application, sensorial, coverage and tint properties. Summary of the invention

[0011] To meet this need, the invention proposes a new cosmetic composition, preferably anhydrous, in solid form for the care and / or makeup of keratinous materials, comprising, in a physiologically acceptable medium: (i) Particles of bismuth oxychloride; (ii) Boron nitride particles; and (iii) At least one wax; characterized in that it comprises less than 3% by weight of titanium dioxide relative to the total weight of the composition and that it has a hardness of at least 30 Nm1.

[0012] Advantageously, the combination of bismuth oxychloride particles and boron nitride particles makes it possible to replace all or part of the titanium dioxide in a cosmetic composition while allowing said cosmetic composition to have good structural, application, sensorial, tinted and covering properties.

[0013] More particularly, for a given solid cosmetic composition comprising titanium dioxide, the combination of bismuth oxychloride particles and boron nitride particles in place of all or part of the titanium dioxide advantageously makes it possible to obtain similar structural, application, sensorial, tint and coverage properties.

[0014] According to one embodiment, the cosmetic composition according to the invention also comprises particles of at least one other inorganic compound selected from zinc oxide, cerium oxide, calcium carbonate, tricalcium phosphate, calcium sulfate, zinc, magnesium or lithium stearate, magnesium carbonate and hydrocarbonate, magnesium myristate, zinc sulfate, barium sulfate, zinc sulfide, aluminum powder, calcined clay, tricalcium phosphate, kaolin, mica, silver, and combinations thereof.

[0015] Advantageously, the addition of particles of at least one other inorganic compound, in addition to the particles of bismuth oxychloride and boron nitride particles, makes it possible to improve the application properties, i.e. to obtain a regular film on the skin, while improving the opacity of the cosmetic composition according to the invention.

[0016] The invention also relates to a method of preparing the composition according to the invention, including in particular a step a) of preparing a mixture comprising particles of bismuth oxychloride, particles of boron nitride and optionally particles of at least one other inorganic compound.

[0017] Preferably, the preparation of step a), intended to replace titanium dioxide, has a clarity measured on a black background defined by a parameter L* greater than 88 and an opacity greater than 82%.

[0018] Finally, the present invention also relates to a cosmetic process for the care and / or makeup of keratinous materials, in particular the skin, eyelids, eyebrows or lips, preferably the lips, comprising the application on said keratinous materials of a cosmetic composition as defined in the invention.

[0019] Other features and advantages will become apparent from the detailed description of the invention and the purely illustrative and in no way limiting examples of the scope of the invention. Detailed description of the invention Definitions

[0020] For the purposes of this invention, "charges" means particles of any shape, colorless or white, of mineral or organic, natural or synthetic nature, which are in a form (platelet, spherical or oblong), insoluble and dispersed in the medium of the composition.

[0021] For the purposes of this invention, "wax" refers to a lipophilic compound, solid at room temperature (approximately 25°C), with a reversible solid / liquid phase change, a melting point above approximately 40°C and up to 200°C, and an anisotropic crystalline structure in the solid state. Generally, the size of the wax crystals is such that the crystals diffract and / or diffuse light, giving the composition containing them a cloudy, more or less opaque appearance. By heating the wax to its melting point, it can be made miscible with oils and form a microscopically homogeneous mixture, but by lowering the mixture's temperature back to room temperature, the wax recrystallizes within the oils of the mixture, detectable both microscopically and macroscopically (opalescence). For a definition of waxes, see, for example, PD Dorgan, Drug and Cosmetic Industry, December 1983, pp. 30-33.

[0022] For the purposes of this invention, "non-polar wax" means a hydrocarbon wax and / or a silicone wax.

[0023] For the purposes of this invention, "nonpolar hydrocarbon wax" means a wax comprising only carbon and hydrogen atoms and not comprising heteroatoms such as oxygen, nitrogen, silicon or phosphorus.

[0024] For the purposes of this invention, "nonpolar siliconized wax" means a wax comprising a silicon heteroatom

[0025] For the purposes of this invention, "polar wax" means a wax comprising at least one heteroatom such as oxygen, nitrogen, silicon or phosphorus.

[0026] By "anhydrous composition" in the sense of the invention, it is understood in particular that water is preferably not deliberately added to the composition according to the invention but may be present in trace amounts in various compounds used in said composition.

[0027] For the purposes of this invention, "solid composition" means a composition exhibiting, at a temperature of 20°C and atmospheric pressure (760 mm Hg), a hardness greater than 30 Nm1, preferably greater than 40 Nm*. Hardness can be measured at 20°C using the "butter cutter wire" method, which assesses the firmness of a solid product by measuring, in particular, its resistance to cutting. This measurement is performed 24 hours after formulation, using a texture analyzer (TAXTPlus, MicroStable Systems, UK) equipped with a 5 kg load cell and its Butter Cutter A / BC probe (Swantech, MicroStable Systems, UK). This method measures the maximum resistance force of the solid product when the butter cutter wire penetrates to a depth of 9 mm at a speed of 1.6 mm / s.To ensure the reproducibility of the measurements, the analysis is repeated on six solid products, and the relative difference between measurements should not exceed 10%, ideally 5%. For each type of product, a reference (target) range is established to guarantee the mechanical properties of the solid cosmetic composition. The solid cosmetic composition according to the invention will generally have a hardness greater than or equal to 70g, in particular greater than or equal to 90g, for example, ranging from 100g to 400g, and preferably from 140g to 300g, and even more preferably from 175g to 250g. Such compositions... (corresponding in particular to cast sticks in standard format of approximately 12.7mm), exhibit adequate stability and hardness: the stick is sufficiently rigid and solid, does not break during application and is thus compatible with packaging in stick form or in another solid form and with application by friction on the surface to be treated and / or made up; they are also characterized by ease of application such as good glide, good deposit from the first application and a comfortable texture.

[0028] For the purposes of this invention, "pasty fat" refers to a lipophilic fatty compound with a reversible solid-liquid phase change, exhibiting an anisotropic crystalline structure in the solid state, and comprising, at a temperature of 23 °C, a liquid fraction and a solid fraction. In other words, the initial melting temperature of the pasty fat may be lower than 23 °C.

[0029] The liquid fraction of the pasty fat measured at 23 °C can represent 9 to 97% by weight of the pasty fat. This liquid fraction at 23 °C preferably represents between 15 and 85%, and even more preferably between 40 and 85% by weight. For the purposes of the invention, the melting temperature corresponds to the temperature of the most endothermic peak observed in differential scanning calorimetry (DSC) as described in ISO 11357-3; 1999. The melting point of a pasty fat can be measured using a differential scanning calorimeter (DSC), for example, the calorimeter sold under the name "MDSC 2920" by TA Instruments.

[0030] The measurement protocol is as follows:

[0031] A 5 mg sample of pasty fat placed in a crucible is subjected to The crucible is first heated from -20 °C to 100 °C at a rate of 10 °C / minute, then cooled from 100 °C to -20 °C at a rate of 10 °C / minute, and finally subjected to a second heating from -20 °C to 100 °C at a rate of 5 °C / minute. During this second heating, the difference in power absorbed by the empty crucible and the crucible containing the pasty fat sample is measured as a function of temperature. The melting point of the pasty fat is the temperature value corresponding to the peak of the curve representing the difference in power absorbed as a function of temperature.

[0032] The liquid fraction by weight of the pasty fat at 23 °C is equal to the ratio of the enthalpy of fusion consumed at 23 °C to the enthalpy of fusion of the pasty fat. The enthalpy of fusion of the pasty fat is the enthalpy consumed by the fat to change from a solid to a liquid state. The pasty fat is said to be in a solid state when its entire mass is in crystalline solid form. The pasty fat is said to be in a liquid state when its entire mass is in liquid form.

[0033] The enthalpy of fusion of the pasty fat is equal to the curve of the thermogram obtained using a differential scanning calorimeter (DS C), such as the calorimeter sold under the name MDSC 2920 by TA instrument, with a temperature rise of 5 or 10 °C per minute, according to ISO 11357-3:1999.

[0034] The enthalpy of fusion of the pasty fat is the amount of energy required to change the pasty fat from a solid to a liquid state. It is expressed in J / g.

[0035] The enthalpy of fusion consumed at 23 °C is the amount of energy absorbed by the sample to pass from the solid state to the state it presents at 23 °C consisting of a liquid fraction and a solid fraction.

[0036] The liquid fraction of the pasty fat measured at 32°C preferably represents 30 to 100% by weight of the pasty fat, preferably 50 to 100%, and preferably 60 to 100% by weight of the pasty fat. When the liquid fraction of the pasty fat measured at 32°C is equal to 100%, the temperature at the end of the melting range of the pasty fat is less than or equal to 32°C.

[0037] The liquid fraction of the pasty fat measured at 32 °C is equal to the ratio of the enthalpy of fusion consumed at 32 °C to the enthalpy of fusion of the pasty fat. The enthalpy of fusion consumed at 32 °C is calculated in the same way as the enthalpy of fusion consumed at 23 °C.

[0263] Preferably, the boron nitride particles, bismuth oxychloride particles and optionally the particles of at least one other inorganic compound from the preparation of step a) have a coating as defined above.

[0264] According to another embodiment, the bismuth oxychloride particles and optionally the particles of at least one other inorganic compound from the preparation in step a) do not have a coating.

[0265] According to one embodiment, the bismuth oxychloride and boron nitride particles represent at least 50% by weight relative to the weight of the mixture of bismuth oxychloride, boron nitride and at least one other inorganic compound particles of the preparation of step a).

[0268] Advantageously, the content of the mixture of bismuth oxychloride particles and boron nitride particles compared to the mixture of bismuth oxychloride particles, boron nitride and at least one other inorganic compound from the preparation of step a) is essential to exhibit characteristics similar to titanium dioxide, in particular satisfactory clarity and opacity.

[0276] Clarity measured on a black background, defined by an L* parameter greater than 88, and opacity greater than 82% are important parameters for evaluating the compatibility of the preparation in step a) with the cosmetic composition according to the invention. Indeed, it is essential, in order to offer an alternative to the use of titanium dioxide, that the preparation in step a) have a clarity measured on a black background, defined by an L* parameter greater than 88, and an opacity greater than 82%. Otherwise, the quantity of preparation in step a) to be added to the composition according to the invention would be too large to obtain coverage and opacity equivalent to that of titanium dioxide, thus creating an imbalance in the cosmetic composition with a significant degradation of the texture, sensory properties, and makeup result: poorer application and uneven application.

[0282] According to one embodiment, the pigment paste from step b) is mixed with at least one wax in liquid form, preferably under agitation.

[0283] Preferably, the wax from step b) is heated to a temperature between 80 and 100°C, more preferably 95°C.

[0284] According to a particular embodiment, the pigment paste from step b) is mixed with a composition comprising at least one wax and optionally at least one oil and / or at least one pasty fat as defined above.

[0287] Preferably, step d) includes the implementation of the following steps: dl) Pouring the mixture from step c) into a suitable mold, preferably at a temperature between 85 and 90°C; d2) Cooling of said mold, preferably in the freezer.

[0288] According to one embodiment, the cosmetic composition according to the invention is obtained by implementing any one of the aforementioned embodiments of the process. Examples

[0289] Example 1: Effect of bismuth oxychloride particles and boron nitride particles on the structure and application and sensory properties of the composition according to the invention

[0290] It has been demonstrated that in order to achieve satisfactory covering and opacifying power, in a solid cosmetic composition, preferably anhydrous, a quantity of bismuth oxychloride particles and boron nitride particles 3 to 4 times greater than the quantity of titanium dioxide was required to obtain an equivalent covering result.

[0291] For the implementation of the protocol in example 1, all the cosmetic compositions are presented in the form of a stick.

[0292] In this example, the control formulation has a lower concentration of titanium dioxide than the concentration of boron nitride and bismuth oxychloride particles in references B and C.

[0293] The addition of this quantity of bismuth oxychloride and / or boron nitride particles tends to destructure the stick, making the deposit on the lips less homogeneous and less covering.

[0294] Surprisingly, the inventors have, in order to compensate for the deleterious effects of bismuth oxychloride particles on the structure of the stick, the covering power of the stick and the homogeneity of the stick, used boron nitride particles.

[0297] Protocol for preparing compositions;

[0298] The compositions are prepared according to the following procedure: a) Preparation of a mixture comprising particles of bismuth oxychloride, particles of boron nitride and optionally particles of at least one other inorganic compound.

[0299] Once the mixing of each particle was carried out in accordance with Table 1, several tests were performed in order to measure the covering and opacifying power of the preparation of step a).

[0300] To this end, the measurement of the clarity defined by the parameter L* and the opacity of these 6 references was carried out according to the following protocol: Preparation of 1 L sample -Disperse 20% by mass of the pigment to be tested in 80% by mass of MARASTAR SR 910 E21 resin -Homogenize the sample by manually stirring with a spatula for 5 minutes -Pass the resulting dispersion through the EXAKT 50i three-cylinder, 1-1 gap -Place the film onto the BYK contrast card using an automatic applicator BYK Byko Drive XL and a 50g dumbbell -Allow the sample to air dry for 30 minutes at room temperature -Verify that the dry thickness is 35 + / - 5pm using a micrometer (palmer)

[0301] Measurement of L* and C on the following samples;

[0302] The parameter L* is determined by measurement using an Xrite CI62 colorimeter on white background and black background.

[0303] Opacity C is determined by measurement using an Xrite CI62 colorimeter on white background and black background.

[0304] The results of the measurement of clarity defined by the parameter L* and opacity are presented in Table 3 below, in particular for references E and F. [Tables 3] Preparation of step a) of reference E Preparation of step a) of reference F Particles INCI name: Bismuth oxychloride Trade name: Pearl Glo SFPG1099 Manufacturer / distributor name: SUN CHEMICALS % by weight 37 10 Particles INCI name: Boron nitride Trade name: PHUP 3000-02 Lexfeel 700 EX LO MB Manufacturer / distributor name: SAINT GOBAIN INOLEX % by weight 60 85 Particles INCI name: Calcium carbonate Trade name: PHUP 3000-02 Manufacturer / distributor name: OMYASKIN KOSTENLO SES MUSTEK % by weight 3 Particles - 5 INCI name: Kaolin Trade name: Kaolin Whitex % by weight Clarity measured on a black background as defined by parameter L* 89.26 89.99 Opacity in % 89.59 86.17

[0305] The preparation of step a) is then dispersed in the dispersant described in Table 1 and mixed with the colouring materials, thus forming a so-called pigment paste.

[0306] The pigment paste is then mixed with the white body at 95°C. Said white body being prepared in the following manner: We weigh and add all the ingredients to a melter under light stirring at 60 to 100 rpm which is heated to 96°C until a transparent liquid without solid particles is obtained.

[0307] The white body comprising a major part of the oils, pasty fats, modified hectorite, preservatives and waxes is weighed and heated to 95°C. Stirring allows homogenization immediately after heating.

[0308] Then the pigment pastes are added. The mixture is passed through a rotor-stator for good homogenization in the medium.

[0309] Additional fillers and / or film-forming agents and / or volatile oils are then added where present, the whole being homogenized before pouring at a temperature between 85 and 90° C. The mold is left to rest at room temperature for 10 minutes before being placed in the freezer for 5 minutes.

[0310] The sticks are unmolded and left to rest at room temperature in their packaging (stick).

[0311] Evaluation of the properties of the sticks obtained _;

[0312] For the implementation of this example, the sticks obtained are evaluated in order to characterize the following parameters: 1 - the structure of the stick, particularly its hardness; and 2- the application and sensory properties, in particular the homogeneity of the deposit and the glide during application.

[0313] The hardness properties of the different sticks are measured at 20°C using the so-called "butter wire" method, which consists of evaluating the firmness of a lipstick by measuring, in particular, its resistance to cutting the product into a stick. This measurement is carried out 24 hours after formulation, using a texture analyzer (TAXTPlus, MicroStable). Systems, UK) equipped with a 5 kg load cell and its Butter Cutter A / BC probe (Swantech, MicroStabil UK). This allows for the measurement of the maximum resistance force of the stick during the penetration of the butter cutter wire to a depth of 9 mm at a speed of 1.6 mm / s. To ensure the reproducibility of the measurements, the analysis is repeated on 6 sticks, and the relative difference between measurements should not exceed 10%, ideally 5%.

[0314] The value obtained for a lipstick stick is generally between 70g and 400g, knowing that for the composition according to the invention, we are looking for a hardness as close as possible to reference A (control) while presenting satisfactory characteristics of solidity, sensoriality, homogeneity and opacity.

[0315] The results of the hardness measurement are described in Table 4 below. [Tables 4] Reference A (control) B (not in invention) C (not in invention) D (according to the invention) E (according to the invention) F (according to the invention) Hardness (g) measured 1 day after manufacture of the stick 180 245 95 114 110 102

[0316] In addition, each stick was tested by a panel of experienced stick users (n=4) in order to evaluate all the sticks on the following parameters: *Sensory experience: Perception felt after applying the stick to the skin; uncomfortable, tight lipstick film, felt 0 / 10; light, comfortable film, does not pull, not drying, 10 / 10 *Homogeneity: Regularity of the stick film deposited on the skin after application, very heterogeneous and discontinuous 0 / 10, regular and continuous 10 / 10 * Application: Easy to obtain a smooth, even film on the skin; lipstick is stiff, dry, and rough (0 / 10); smooth, non-sticky, and soft (10 / 10) *Opacity: Colored stick film that hides the skin, transparent film 0 / 10, covering and opaque film 10 / 10.

[0317] The results of the study are described below: [Tables 5] References: Sensory quality, Homogeneity, Applications, Opacity, Average A (control) 9 9 8 10 9 B (outside invention) 7 5 7 5 6 C (outside the invention) 8 5 4 7 6 D (according to the invention) 7 7 5 8 6.75 E (according to the invention) 9 7 7 9 8 F (according to the invention) 9 7 6 9 7.75

[0318] These results show that the use of boron nitride particles in a composition containing bismuth oxychloride particles, replacing titanium dioxide and in sufficient quantity to obtain equivalent coverage, compensates for the adverse effects of bismuth oxychloride particles on the structure, and more specifically on homogeneity. Furthermore, this example also demonstrates that adding another inorganic compound, such as kaolin and calcium carbonate, balances the perceived characteristics of the studied parameters, such as sensory appeal and makeup results, with homogeneity of application, ease of application, and coverage of solid cosmetic compositions.

[0319] Table 6 below presents a summary of user panel comments for all sticks in this example. [Tableauxô] References Comments A This stick offers good sensory and makeup results. B This stick has a high rigidity; however, the makeup result is not satisfactory. Indeed, this stick has a greasy and oily feel upon application, and the makeup result—ease of application and evenness of application—is degraded. C This stick is quite soft, resulting in a larger deposit. Consequently, this stick offers better coverage with a thick (and not thin as desired) finish, but it is not evenly applied. It is not easy to apply. D This stick offers improved coverage compared to references B and C. The stick has an intermediate rigidity, falling between references B and C. Although satisfactory, the evenness of application and ease of application are not as good as those of reference A. This stick offers satisfactory tactile feel and opacity, with a tint and texture similar to those obtained with reference AF. This stick offers satisfactory tactile feel and opacity, with a tint and texture similar to those obtained with reference A.

[0320] Example 2: Measuring the shade of different lipstick sticks

[0321] For the purposes of this example, lipstick sticks G, H and I are sticks made from the same white body as described in example 1.

[0322] The objective of this example is to replace the titanium dioxide present in the control stick with bismuth oxychloride particles and boron nitride particles.

[0323] All the sticks were prepared following the same protocol as that described in example 1.

[0324] Several tests were carried out beforehand to determine the covering and opacifying power of the preparation comprising the mixture of bismuth oxychloride particles and boron nitride particles and at least one other inorganic compound, in order to be able to replace titanium dioxide in formulas, without impacting the desired coverage effect.

[0325] All the sticks are prepared following the same protocol as described in example 1.

[0326] The compositions of the different sticks used in this example are described in Table 7 below. [Paintings?] Ingredients Composition G (control) % Composition H (according to the invention) % Composition I (according to the invention) % White body - composition described in Table 2 63 63 63 Pigment INCI Name: Titanium Dioxide Trade Name: Titanium Dioxide W877 Manufacturer / Distributor Name: SENSIENT COSMETIC 5.21 Mixture 1 - 16 - Mixture 2 - - 16 Colorants 21.370 14.4 14.4 Dispersant INCI Name: pentaerythrityl adi-pate / caprate / caprylate / heptanoate Trade Name: Lexfeel 700 EX LO MB Manufacturer / Distributor Name: INOLEX QSP100 QSP100 QSP100

[0327] Mixture 1 consisting of: - 5% of zinc oxide particles by weight relative to the weight of mixture 1; - 35% bismuth oxychloride particles by weight relative to the weight of mixture 1; and - 60% boron nitride particles by weight relative to the weight of mixture 1.

[0328] Mixture 2, for its part, consists of: - 3% calcium carbonate particles by weight relative to the weight of the mixture 1; - 35% bismuth oxychloride particles by weight relative to the weight of mixture 1; and - 60% boron nitride particles by weight relative to the weight of mixture 1.

[0329] Method for measuring the colorimetric coordinates of lipsticks

[0330] Each lipstick composition is applied in eight successive passes on a contrast card with a black background.

[0331] Using a spectrophotometer, measurement of colorimetric coordinates on the L*a*b* CIE 1976 chromatic space.

[0332] DC Definition: The AC deviation is a measure of the difference in chromaticity between two colors and is calculated as follows: ACAM(aA(*A2 )+ bA* 2)

[0333] A DC of less than 2 means that the variation in shade between the references is not perceptible to the human eye

[0334] The results of the colorimetric coordinate measurement are described in Table 8 below. [Tables 8] DC on a black background / DC on a black background of composition G (control) Composition H (according to the invention) 1.57 Composition I (according to the invention) 1.92

[0335] The results demonstrate that the use of bismuth oxychloride particles and boron nitride particles and optionally at least one other inorganic compound makes it possible to effectively replace titanium dioxide without affecting the shade despite a higher content within the cosmetic composition according to the invention.

[0336] Example 3: Coverage and opacity of a mixture of bismuth oxychloride particles and boron nitride particles in dispersion state before incorporation into a lipstick formulation:

[0337] Several tests were carried out to determine the covering and opacifying power of the mixture comprising particles of bismuth oxychloride, boron nitride particles and optionally at least one other inorganic compound, compared with titanium dioxide, in order to be able to replace titanium dioxide in formulas, without impacting the desired coverage effect.

[0338] The measurement of clarity defined by the parameter L* and of opacity is carried out according to the same protocol as that described in example 1.

[0339] For the performance of the tests, 2 compositions were used, and are presented in Table 9.

[0340] The results presented in this example demonstrate that preparations J and K exhibit a clarity defined by a parameter L* and a satisfactory opacity to offer an alternative to the use of titanium dioxide in solid cosmetic compositions.
