Film-forming compositions and lip makeup products containing them

[0001] Cross-reference of related applications

[0002] This application claims priority to Chinese Patent Application No. 202411549638.0, filed on October 31, 2024, entitled “Film-forming Composition and Lip Makeup Product Containing the Thereof,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the field of cosmetic technology, specifically relating to a film-forming composition and a lip makeup product containing the same. Background Technology

[0004] Lipstick and other lip makeup products are cosmetics primarily applied to the lips to enhance or alter their color, and are an important type of makeup. The main ingredients of lip makeup products can include colorants, fillers, waxes, oils, pearlescent agents, fragrances, and preservatives. Colorants contain pigments or dyes, dispersed in a homogeneous carrier formed by waxes and other oil components, allowing lip makeup products to present different shades.

[0005] Lip makeup products can generally be divided into glossy lip makeup products and matte lip makeup products according to their gloss level. Although existing glossy lip makeup products can achieve a glossy effect, the colorants (such as pigments) in glossy lip makeup products are miscible with the oil components. When lips with glossy lip makeup products come into contact with smooth objects (such as glasses, the back of the hand, etc.), the colorants in the makeup products are easily left on the surface of the smooth objects along with the oil components, resulting in phenomena such as transfer and fading. Summary of the Invention

[0006] To address the aforementioned problems, this application provides a film-forming composition and a lip makeup product comprising the same. When applied to a lip makeup product formulation, this film-forming composition can rapidly form an oil film and exhibits good film-forming properties, thereby helping to reduce phenomena such as transfer and color fading in lip makeup products.

[0007] A first aspect of this application provides a film-forming composition comprising the following components:

[0008] Phenyl silicone oil: includes two or more of diphenyl polydimethylsiloxane, trimethylpentaphenyltrisiloxane, phenyl polytrimethylsiloxane, and trimethylsiloxaneoxyphenyl polydimethylsiloxane; the viscosity of phenyl silicone oil at 25°C is 50 mPa·s to 500 mPa·s;

[0009] Film-forming agent: including at least one of hydrogenated polyisobutylene and polyisobutylene; and the viscosity of the film-forming agent at 75°C is 1500 mPa·s to 2500 mPa·s;

[0010] The mass ratio of the phenyl silicone oil to the film-forming agent is (2-5):1.

[0011] Not intended to be limited by any theory or interpretation, the film-forming composition of this application, having the above-described composition and with the viscosity and mass ratio of phenyl silicone oil and film-forming agent within the aforementioned suitable range, can interact to form an oil film when applied to a lip makeup product formulation system, exhibiting a good film-forming effect. Therefore, when a lip makeup product using this film-forming composition is applied to the lips, a portion of the oil phase can quickly form a long-lasting and stable high-gloss oil film on the surface. Thus, when the lips come into contact with a smooth object (e.g., a glass, the back of a hand), only an oil film will remain on the object's surface; the colorant in the product will not adhere to the object's surface with the oil film, thereby achieving a non-stick and non-fading effect. It is particularly noteworthy that selecting phenyl silicone oil and film-forming agent components with suitable viscosity ranges plays a crucial role in film-forming time and effect. The film-forming composition of this application, using the aforementioned phenyl silicone oil and film-forming agent within suitable viscosity ranges, when applied to a lip makeup product formulation system, can shorten the film-forming time to less than 1 minute and achieve a good film-forming effect.

[0012] In any embodiment of this application, the viscosity of the phenyl silicone oil at 25°C is 150 mPa·s to 350 mPa·s.

[0017] In any embodiment of this application, the mass ratio of film-forming aid to film-forming agent is (0.1-0.5):1, preferably (0.2-0.4):1.

[0018] In any embodiment of this application, phytosterols or their derivatives are selected from one or more of the following: bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate, phytosterol / isostearyl / cetearyl alcohol / behenol di-linoleate, phytosterol macadamia oleate, phytosterol isostearate, phytosterol oleate, phytosterol isostearol di-linoleate, and bis-behenol / phytosterol di-linoleate.

[0019] In any embodiment of this application, the film-forming composition comprises the following components:

[0020] Phenyl silicone oil: composed of diphenyl polydimethylsiloxane, trimethylpentaphenyltrisiloxane, trimethylsiloxane-oxyphenyl polydimethylsiloxane, and phenyl polytrimethylsiloxane; and the viscosity of phenyl silicone oil at 25°C is 150 mPa·s to 350 mPa·s;

[0021] Film-forming agent: composed of hydrogenated polyisobutylene, VP / hexadecene copolymer and acrylate copolymer; and the viscosity of the film-forming agent at 75°C is 1800 mPa·s~2200 mPa·s;

[0022] Film-forming aid: is bis-benzyl alcohol / isostearyl alcohol / phytosterol dimeric linoleic acid dimeric linoleate; and the dynamic viscosity of the film-forming aid at 60°C is 450 mPa·s~550 mPa·s.

[0023] In any embodiment of this application, the mass ratio of phenyl silicone oil, film-forming agent, and film-forming aid is (2.5-4):1:(0.2-0.4).

[0024] A second aspect of this application provides a lip makeup product, comprising the film-forming composition of the first aspect.

[0025] In any embodiment of this application, the mass percentage of the film-forming composition is 80% to 94% based on the total mass of the lip makeup product.

[0026] In any embodiment of this application, the lip makeup product may further include at least one of the following: lip makeup product waxes, fillers, colorants, oils, pearlescent agents, fragrances, preservatives, emulsifiers, dispersants, and thickeners. Attached Figure Description

[0028] To make the purpose, technical solution, and beneficial technical effects of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the embodiments described in this specification are merely for explaining this application and are not intended to limit it.

[0029] For simplicity, this application only explicitly discloses some numerical ranges. However, any lower limit can be combined with any upper limit to form a range not explicitly stated; and any lower limit can be combined with other lower limits to form a range not explicitly stated, just as any upper limit can be combined with any other upper limit to form a range not explicitly stated. Furthermore, although not explicitly stated, every point or individual value between the endpoints of the range is included within that range. Therefore, each point or individual value can be used as its own lower or upper limit and combined with any other point or individual value or with other lower or upper limits to form a range not explicitly stated.

[0030] In the description of this application, it should be noted that, unless otherwise stated, "above" and "below" include the stated number, and "multiple" in "one or more" means two or more.

[0031] The foregoing description of this application is not intended to describe every disclosed implementation or method. Instead, the following description provides more specific examples of exemplary embodiments. Throughout the application, guidance is provided through a series of embodiments that can be used in various combinations. The examples listed are representative only and should not be construed as exhaustive.

[0032] As described in the background art, the colorants (such as pigments) in glossy lip makeup products are miscible with oil components. When the lips with glossy lip makeup products come into contact with a smooth object (such as a glass, the back of a hand, etc.), the colorants are easily left on the surface of the smooth object along with the oil components, resulting in phenomena such as sticking to the cup and fading.

[0033] In view of this, the inventors, through in-depth research and extensive experimentation, have provided a film-forming composition and a lip makeup product containing the same.

[0034] The first aspect of this application provides a film-forming composition comprising phenyl silicone oil and a film-forming agent.

[0035] The aforementioned phenyl silicone oil includes two or more of the following: diphenyl polydimethylsiloxane, trimethylpentaphenyltrisiloxane, phenyl polytrimethylsiloxane, and trimethylsiloxaneoxyphenyl polydimethylsiloxane. The viscosity of this phenyl silicone oil at 25°C is 50 mPa·s to 500 mPa·s, for example, it can be 50 mPa·s, 100 mPa·s, 150 mPa·s, 200 mPa·s, 250 mPa·s, 300 mPa·s, 350 mPa·s, 400 mPa·s, 450 mPa·s, 500 mPa·s, or within any range of two of the aforementioned values.

[0036] The aforementioned film-forming agent includes at least one of hydrogenated polyisobutylene and polyisobutylene. The viscosity of this film-forming agent at 75°C is 1500 mPa·s to 2500 mPa·s, for example, it can be 1500 mPa·s, 1600 mPa·s, 1700 mPa·s, 1800 mPa·s, 1900 mPa·s, 2000 mPa·s, 2100 mPa·s, 2200 mPa·s, 2300 mPa·s, 2400 mPa·s, 2500 mPa·s, or within any range of two of the aforementioned values.

[0037] In the film-forming composition of this application, the mass ratio of phenyl silicone oil to film-forming agent can be (2 to 5):1, for example, it can be 2:1, 3:1, 4:1, 5:1, or within any range of two of the above ratios.

[0038] In the embodiments of this application, the viscosity of each material has a meaning known in the art and can be determined by equipment and methods known in the art. For example, it can be determined with reference to the testing standard GB / T265-1988.

[0039] In the embodiments of this application, the viscosity of the phenyl silicone oil can be controlled in various ways. For example, the viscosity of the phenyl silicone oil can be adjusted by controlling the components of the phenyl silicone oil, the content of each component in the phenyl silicone oil, and the viscosity of each component in the phenyl silicone oil, so that the viscosity of the phenyl silicone oil meets the above-mentioned range. Those skilled in the art can select appropriate control methods as needed, and this application does not limit them.

[0040] In the embodiments of this application, the viscosity of the film-forming agent can be controlled in various ways. For example, the viscosity of the film-forming agent can be adjusted by controlling the components of the film-forming agent, the content of each component in the film-forming agent, and the viscosity of each component in the film-forming agent, so that the viscosity of the film-forming agent meets the above-mentioned range. Those skilled in the art can select appropriate control methods as needed, and this application does not limit them.

[0041] Not intended to be limited by any theory or interpretation, the film-forming composition of this application, having the above-described composition and with the viscosity and mass ratio of phenyl silicone oil and film-forming agent within the aforementioned suitable range, can interact to form an oil film when applied to a lip makeup product formulation system, exhibiting a good film-forming effect. Therefore, when a lip makeup product using this film-forming composition is applied to the lips, a portion of the oil phase can quickly form a long-lasting and stable high-gloss oil film on the surface, with a film-forming time of less than 1 minute. Thus, when the lips come into contact with a smooth object (such as a glass, the back of a hand, etc.), only an oil film will remain on the object's surface; the colorant in the product will not adhere to the object's surface with the oil film, thereby achieving a non-sticky and non-fading effect.

[0042] In some embodiments, the viscosity of the phenyl silicone oil at 25°C can be 150 mPa·s to 350 mPa·s, for example, it can be 150 mPa·s, 180 mPa·s, 200 mPa·s, 250 mPa·s, 280 mPa·s, 300 mPa·s, 350 mPa·s, or within the range of any two of the above values.

[0043] In some embodiments, the viscosity of the film-forming agent at 75°C can be 1800 mPa·s to 2200 mPa·s, for example, it can be 1800 mPa·s, 1900 mPa·s, 2000 mPa·s, 2100 mPa·s, 2200 mPa·s, or within the range of any two of the above values.

[0044] Not intended to be limited by any theory or explanation, when the viscosity of phenyl silicone oil and / or film-forming agent meets the above range, the film-forming composition of this application can be applied to the formulation system of lip makeup products, which can further shorten the film-forming time.

[0045] In some embodiments, the mass ratio of phenyl silicone oil to film-forming agent can be (2.5 to 4):1, for example, it can be 2.5:1, 3:1, 3.5:1, 4:1, or within any range of two of the above ratios.

[0046] When the mass ratio of phenyl silicone oil to film-forming agent is within the aforementioned suitable range, the film-forming composition of this application, when applied to a lip makeup product formulation system, ensures rapid film formation and, while maintaining a good film-forming effect, exhibits excellent spreadability and moisturizing properties. This not only achieves a non-transferable and long-lasting effect but also enhances the skin feel of the lip makeup product.

[0047] In some embodiments, the film-forming agent may also include one or more of the following: acrylic (ester) copolymers, VP / hexadecene copolymers, VP / eicosene copolymers, trimethylsiloxysilicates, polymethylsilsesquioxanes, polypropylsilsesquioxanes, acrylic (ester) / polytrimethylsiloxane methacrylate copolymers, hydrogenated polycyclopentadiene, hydrogenated (styrene / methylstyrene / indene) copolymers, ethylene / propylene / styrene copolymers, butene / ethylene / styrene copolymers, bis-hydroxyethoxypropyl polydimethylsiloxane / IPDI copolymer urethane, bis-PEG-15 polydimethylsiloxane / IPDI copolymers, bis-hydroxypropyl polydimethylsiloxane / SMDI copolymers, polyurethanes, polyesters, and glycerol hydrogenated rosinates.

[0048] In some embodiments, the film-forming composition may further include a film-forming aid. The film-forming aid may be a phytosterol or a derivative thereof, and the viscosity of the film-forming aid at 60°C may be 300 mPa·s to 700 mPa·s, for example, 300 mPa·s, 400 mPa·s, 500 mPa·s, 600 mPa·s, 700 mPa·s, or within any two of the above values.

[0049] In some embodiments, the viscosity of the film-forming aid at 60°C can be 450 mPa·s to 550 mPa·s, for example, it can be 450 mPa·s, 480 mPa·s, 500 mPa·s, 520 mPa·s, 550 mPa·s, or within the range of any two of the above values.

[0050] Not intended to be limited to any particular theory or explanation, the film-forming aids selected from the above-mentioned types and possessing specific viscosities, when applied to the film-forming system, not only ensure film-forming time and effect but also make the oil film reproducible and result in a three-dimensional, full-bodied film. Therefore, when a lip makeup product using the film-forming composition of this application is applied to the lips, and the lips come into contact with a smooth object (such as a glass, the back of a hand, etc.), the oil film on the surface remains. At this point, the residual oil phase on the lips can quickly form a new oil film under the action of the film-forming aids, thus achieving film reproducibility. In this way, even if the lips come into contact with a smooth object multiple times, a glossy effect can still be maintained. This allows the lips to maintain a three-dimensional, full, and moisturized visual effect for a long time.

[0051] In some embodiments, the mass ratio of film-forming aid to film-forming agent can be (0.1 to 0.5):1, for example, it can be 0.1:1, 0.2:1, 0.3:1, 0.4:1, 0.5:1, or within any two of the above ratios.

[0052] In some embodiments, the mass ratio of film-forming aid to film-forming agent may be (0.2 to 0.4):1, for example, it may be 0.2:1, 0.25:1, 0.3:1, 0.35:1, 0.4:1, or within any range of two of the above ratios.

[0053] When the mass ratio of film-forming aid to film-forming agent is within the above-mentioned appropriate range, the reproducibility of the oil film can be made more durable and the three-dimensional fullness of the film can be optimized.

[0054] In some embodiments, phytosterols or their derivatives may be selected from one or more of the following: bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleate, phytosterol / isostearyl / cetearyl alcohol / behenol di-linoleate, phytosterol macadamia oleate, phytosterol isostearate, phytosterol oleate, phytosterol isostearol di-linoleate, and bis-behenol / phytosterol di-linoleate.

[0055] In some embodiments, the film-forming composition comprises phenyl silicone oil, a film-forming agent, and a film-forming aid.

[0056] The aforementioned phenyl silicone oil is composed of diphenyl polydimethylsiloxane, trimethylpentaphenyltrisiloxane, trimethylsiloxane-oxyphenyl polydimethylsiloxane, and phenyl polytrimethylsiloxane. Furthermore, the viscosity of this phenyl silicone oil at 25°C is 150 mPa·s to 350 mPa·s.

[0057] The aforementioned film-forming agent is composed of hydrogenated polyisobutylene, VP / hexadecene copolymer, and acrylate copolymer. Furthermore, the viscosity of this film-forming agent at 75°C is 1800 mPa·s to 2200 mPa·s.

[0058] The aforementioned film-forming aid is bis-benzyl alcohol / isostearyl alcohol / phytosterol dimeric linoleic acid dimeric linoleate. Furthermore, the viscosity of this film-forming aid at 60°C is 450 mPa·s to 550 mPa·s.

[0059] In some embodiments, the mass ratio of phenyl silicone oil, film-forming agent, and film-forming aid may be (2.5–4):1:(0.2–0.4).

[0060] In some embodiments, the viscosity of diphenyl polydimethylsiloxane at 25°C can be 3000 Pa·s to 7000 mPa·s, for example, it can be 3000 mPa·s, 4000 mPa·s, 5000 mPa·s, 6000 mPa·s, 7000 mPa·s, or within the range of any two of the above values.

[0061] In some embodiments, the viscosity of trimethylpentaphenyltrisiloxane at 25°C can be 165 cst to 185 cst, for example, it can be 165 cst, 170 cst, 175 cst, 180 cst, 185 cst, or within the range of any two of the above values.

[0062] The viscosity of trimethylsiloxane-oxyphenyl polydimethylsiloxane at 25°C is 15 mm. 2 / s~25mm 2 / s, for example, can be 15mm 2 / s, 18mm 2 / s, 20mm 2 / s, 25mm 2 / s, or within the range of any two of the above values.

[0063] The viscosity of phenyl polytrimethylsiloxane at 25°C can be 22 mPa·s to 28 mPa·s, for example, it can be 22 mPa·s, 24 mPa·s, 26 mPa·s, 28 mPa·s, or within any two of the above values.

[0064] The viscosity of bis-behenol / isostearyl / phytosterol di-linoleyl alcohol di-linoleic acid ester at 60°C can be 450 mPa·s to 550 mPa·s, for example, 450 mPa·s, 480 mPa·s, 500 mPa·s, 520 mPa·s, 550 mPa·s, or within any two of the above values.

[0065] The viscosity of hydrogenated polyisobutylene at 100°C is 600 cst to 800 cst, for example, it can be 600 cst, 620 cst, 650 cst, 680 cst, 700 cst, 720 cst, 750 cst, 780 cst, 800 cst, or within any two of the above values.

[0066] According to the above embodiments, the viscosity of each component of the phenyl silicone oil, film-forming aid, and film-forming agent is within a suitable range, which allows the phenyl silicone oil, film-forming aid, and film-forming agent to have suitable viscosity. This is beneficial for further improving the film-forming effect of the film-forming composition.

It is understood that after the lip makeup products of this application embodiment are applied to the lips, a portion of the oil phase can rapidly form a long-lasting and stable high-gloss oil film on the surface within 1 minute. Thus, when the lips come into contact with a smooth object (such as a glass, the back of a hand, etc.), only an oil film will remain on the surface of the object, and the colorant in the product will not adhere to the object surface with the oil film, thereby achieving a non-sticky and non-fading effect.

[0094] (1) Heat and stir phase A at 92℃~98℃ to dissolve phase A and obtain a first liquid, wherein phase A includes a film-forming composition, isohexadecane, synthetic wax, sorbitan oleate and tocopherol acetate.

[0095] (2) Add phase B to the first liquid at 92℃~98℃ and stir until phase B is completely dissolved to obtain the second liquid, wherein phase B is ethylhexylglycerol.

[0096] (3) The second liquid is mixed with the C phase and stirred evenly, and then ground to disperse the pigment particles in the C phase to obtain the first mixture, wherein the C phase includes silachlorite, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosslinked polymer and pigment.

[0097] (4) The first mixture is heated and stirred at 92℃~98℃ to obtain the second mixture.

[0098] (5) Stir the second mixture with phase D at 82℃~88℃ to obtain a paste of mixture, where phase D includes butanediol and fragrance.

[0099] (6) Stir the mixture and degas it under vacuum to obtain a semi-finished lipstick.

[0100] (7) Filter the material and seal it to obtain lipstick.

[0101] Based on the total mass of the lipstick raw materials as 100%, the film-forming composition contains 88.79% by mass, isohexadecane 2.80% by mass, synthetic wax 3.77% by mass, sorbitan olive oil ester 0.10% by mass, tocopheryl acetate 0.15% by mass, ethylhexylglycerin 0.20% by mass, silachlorite 1.00% by mass, vinyl polydimethylsiloxane / polymethylsiloxane silsesquioxane crosspolymer 1.60% by mass, pigment 1.39% by mass, butanediol 0.05% by mass, and fragrance 0.15% by mass.

[0102] The composition and related parameters of the film-forming composition are shown in Table 1.

[0103] Examples 2-18

[0104] The lipsticks of Examples 2-18 were prepared by adjusting the composition and related parameters of the film-forming composition according to Table 1. The preparation process of the lipsticks of Examples 2-18 was the same as that of Example 1.

[0105] Comparative Examples 1-6

[0106] According to Table 1, the composition and related parameters of the film-forming composition were adjusted to prepare lipsticks of Comparative Examples 1 to 6. The preparation process of lipsticks of Comparative Examples 1 to 6 was the same as that of Example 1.

[0107] Test section

[0108] (1) Tack test

[0109] a. Tack test on smooth skin surface

[0110] The lipstick was applied to the subject's lips, and a stopwatch was started immediately. After 1 minute, the lips with lipstick were gently touched to the skin of the arm, and the traces on the skin were observed to assess the degree of lipstick transfer.

[0111] b. Glass surface sticking test

[0112] Apply the lipstick to the subject's lips and immediately start the stopwatch. After 1 minute, use a clean, transparent glass to gently press the lips with the glass and then observe the marks on the glass to assess the degree of lipstick transfer.

[0113] (2) Film formation time test

[0114] After the lipstick was evenly applied to the subject's lips, a stopwatch was immediately started. Three parallel experiments were designed for each example or control group of lipstick, with each experiment conducted at specific time points. The specific procedures were as follows:

[0115] In the first parallel experiment, 10 seconds after the start of the timer, the lips coated with lipstick were gently touched to the skin of the arm, and any pigment residue was observed on the skin surface. The second parallel experiment performed the same test at 20 seconds. The third parallel experiment performed the same test at 1 minute.

[0116] Through the above operations, the amount of pigment residue remaining on the lower lip after contact with the skin of the arm was recorded at each time point. The shortest time with no pigment residue on the skin surface was taken as the film-forming time of the lipstick.

[0117] (3) Reproduction test

[0118] After evenly applying the lipstick to your lips, immediately start a stopwatch. Stop the timer after one minute and gently touch your lips, still coated with lipstick, to your arm to check for any pigment residue. If no residue remains, repeat the process after one minute, touching your arm again to check for any remaining pigment. Repeat this process three times. If no pigment residue remains, the lipstick is reproducible.

[0119] The test results of each embodiment and comparative example are shown in Table 2.

[0120] In Table 1, "√" indicates that the corresponding substance has been added, and " / " indicates that the corresponding substance has not been added or the corresponding parameter has not been tested.

[0121] Table 2

[0122] In Table 2, "non-stick" indicates that no sticking occurred in both the sticking test on smooth skin and the sticking test on glass. "Sticking" indicates that sticking occurred in both the sticking test on smooth skin and the sticking test on glass.

[0123] As can be seen from Tables 1 and 2, the film-forming composition of this application has a specific composition, and the viscosity and mass ratio of phenyl silicone oil and film-forming agent are within a specific range. When applied to lipstick systems, it can effectively shorten the film-forming time to within 1 minute and achieve a better film-forming effect, making the lipstick non-sticky and colorfast.

[0124] Furthermore, as can be seen from Examples 1-8, when the viscosity of the phenyl silicone oil in the film-forming composition, the viscosity of the film-forming agent, and the mass ratio of phenyl silicone oil to the film-forming agent are within a suitable range, the film-forming time can be further shortened. As can be seen from Examples 1-8, 9-16, and 17-18, adding an appropriate amount of film-forming aid with suitable viscosity to the film-forming composition can ensure the reproducibility of the lipstick while maintaining the film-forming time and effect.

[0125] In contrast, the viscosity of the phenyl silicone oil in Comparative Examples 1-2 is outside the range of this application; the viscosity of the film-forming agent in Comparative Examples 3-4 is outside the range of this application; and the mass ratio of phenyl silicone oil to film-forming agent in Comparative Examples 5-6 is outside the range of this application. Therefore, Comparative Examples 1-6 not only have longer film-forming times but also significantly inferior film-forming effects compared to Examples 1-18, all exhibiting sticking phenomena in the sticking cup test. For example, referring to Figure 1, the lipstick of Example 1, after being applied to the lips for 1 minute and coming into contact with the skin of the arm, only left a colorless oil film on the surface of the arm. However, the lipstick of Comparative Example 2, after being applied to the lips for 1 minute and coming into contact with the skin of the arm, left pigment residue on the surface of the arm, forming a noticeable colored lip print.

[0126] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
