Description

Technical Field

[0001] The present application belongs to the technical field of cosmetics, and specifically relates to a film-forming composition and a lip makeup product containing the same. Background Art

[0002] Lip makeup products such as lipstick are cosmetics that are mainly applied to the lips to increase the luster of the lips or change the color of the lips. They are one of the important makeup products. The raw materials of lip makeup products can mainly include colorants, fillers, waxes, oils, pearlescent agents, flavors and preservatives. Colorants contain pigments or dyes, which are dispersed in a uniform carrier formed by waxes and other oil components, which can make lip makeup products present different tones.

[0003] Lip makeup products can be generally divided into glossy lip makeup products and matte lip makeup products according to their glossiness. Although existing glossy lip makeup products can present a glossy effect, the colorant (such as color powder, etc.) in the glossy lip makeup products is miscible with the oil component. When the lips coated with the glossy lip makeup products come into contact with smooth objects (such as glass cups, backs of hands, etc.), the colorant in the makeup products is easy to remain on the surface of the smooth objects together with the oil component, resulting in cup staining, color fading, etc. Summary of the invention

[0004] To solve the above problems, the present application provides a film-forming composition and a lip makeup product containing the same. The film-forming composition is applied to the lip makeup product formula system, can quickly form an oil film, and has a good film-forming effect, thereby helping to reduce the phenomenon of cup sticking and color fading of the lip makeup product.

[0005] The first aspect of the present application provides a film-forming composition, comprising the following components:

[0006] Phenyl silicone oil: including two or more of diphenyl polydimethylsiloxane, trimethyl pentaphenyl trisiloxane, phenyl polytrimethylsiloxane, trimethylsiloxyphenyl polydimethylsiloxane; the viscosity of phenyl silicone oil at 25°C is 50mPa·s to 500mPa·s;

[0007] Film-forming agent: comprising 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;

[0008] The mass ratio of the above-mentioned phenyl silicone oil to the film-forming agent is (2-5):1.

[0009] It is not intended to be limited to any theory or explanation. The film-forming composition of the present application has the above composition, and the viscosity and mass ratio of the phenyl silicone oil and the film-forming agent are within the above-mentioned suitable range. It is applied to the lip makeup product formula system, and can interact to form an oil film, and has a good film-forming effect. Thus, after the lip makeup product using the film-forming composition is applied to the lips, part of the oil phase can quickly form a durable and stable high-gloss oil film on the surface.

[0026] In order to make the application purpose, technical solution and beneficial technical effect of the present application clearer, the present application is further described in detail in conjunction with the embodiments below. It should be understood that the embodiments described in this specification are only for explaining the present application, not for limiting the present application.

[0027] For simplicity, this application only explicitly discloses some numerical ranges. However, any lower limit can be combined with any upper limit to form an unclearly recorded range; and any lower limit can be combined with other lower limits to form an unclearly recorded range, and any upper limit can be combined with any other upper limit to form an unclearly recorded range. In addition, although not clearly recorded, each point or single value between the range endpoints is included in the range. Thus, each point or single value can be combined with any other point or single value as its own lower limit or upper limit or with other lower limits or upper limits to form an unclearly recorded range.

[0028] In the description of the present application, it should be noted that, unless otherwise specified, “above” and “below” are inclusive of the number, and the “multiple” in “one or more” means two or more than two.

[0029] The above application content of the present application is not intended to describe each disclosed embodiment or each implementation in the present application. The following description more specifically illustrates exemplary embodiments. In many places throughout the application, guidance is provided by a series of examples, which can be used in various combinations. In each example, enumeration is only used as a representative group and should not be interpreted as exhaustive.

[0030] As described in the background technology, the colorant (such as toner, etc.) in the glossy lip makeup product is soluble in the oil component. When the lips coated with the glossy lip makeup product come into contact with a smooth object (such as a glass, the back of the hand, etc.), the colorant is easily retained on the surface of the smooth object together with the oil component, resulting in cup staining, color fading, etc.

[0031] In view of this, the inventors, after in-depth research and extensive experiments, provide a film-forming composition and a lip makeup product containing the same.

[0032] In a first aspect, the present application provides a film-forming composition, comprising phenyl silicone oil and a film-forming agent.

[0033] The phenyl silicone oil comprises two or more of diphenyl polydimethylsiloxane, trimethyl pentaphenyl trisiloxane, phenyl polytrimethylsiloxane, and trimethylsiloxyphenyl polydimethylsiloxane. The viscosity of the phenyl silicone oil at 25° C. is 50 mPa·s to 500 mPa·s, for example, 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 is within the range of any two of the above values.

[0034] The film-forming agent includes at least one of hydrogenated polyisobutylene and polyisobutylene. The viscosity of the film-forming agent at 75° C. is 1500 mPa·s to 2500 mPa·s, for example, 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 is within the range of any two of the above values.

[0035] In the film-forming composition of the present application, the mass ratio of phenyl silicone oil to film-forming agent can be (2-5):1, for example, 2:1, 3:1, 4:1, 5:1, or within the range of any two of the above ratios.

[0036] In the examples of the present application, the viscosity of each material has a well-known meaning in the art and can be measured by equipment and methods known in the art. For example, it can be measured with reference to the test standard GB / T265-1988.

[0037] In the embodiments of the present application, the viscosity of the phenyl silicone oil can be regulated in a variety of ways. For example, the viscosity of the phenyl silicone oil can be adjusted to meet the above range by adjusting the components of the phenyl silicone oil, the content of each component in the phenyl silicone oil, the viscosity of each component in the phenyl silicone oil, etc. Those skilled in the art can select a suitable regulation method as needed, and the present application is not limited thereto.

[0038] In the embodiments of the present application, the viscosity of the film-forming agent can be regulated in a variety of ways. For example, the viscosity of the film-forming agent can be adjusted to meet the above range by adjusting the components of the film-forming agent, the content of each component in the film-forming agent, the viscosity of each component in the film-forming agent, etc. Those skilled in the art can select a suitable regulation method as needed, and the present application does not limit this.

[0039] Without intending to be limited by any theory or explanation, the film-forming composition of the present application has the above composition, and the viscosity and mass ratio of the phenyl silicone oil and the film-forming agent are within the above appropriate range. When applied to the lip makeup product formula system, they can interact to form an oil film and have a good film-forming effect. Therefore, after the lip makeup product using the film-forming composition is applied to the lips, part of the oil phase can quickly form a durable and stable high-gloss oil film on the surface, and the film-forming time is within 1 minute. In this way, after the lips come into contact with a smooth object (such as a glass, the back of the hand, etc.), only an oil film will be left on the surface of the object, and the colorant in the product will not be stained with the oil film on the surface of the object, thereby achieving the effect of not sticking to the cup and not fading.

[0040] In some embodiments, the viscosity of phenyl silicone oil at 25°C can be 150mPa·s to 350mPa·s, for example, 150mPa·s, 180mPa·s, 200mPa·s, 250mPa·s, 280mPa·s, 300mPa·s, 350mPa·s, or within the range of any two of the above values.

[0041] In some embodiments, the viscosity of the film-forming agent at 75° C. may be 1800 mPa·s to 2200 mPa·s, for example, 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.

[0042] Without intending to be limited by any theory or explanation, when the viscosity of the phenyl silicone oil and / or the film-forming agent meets the above range, the film-forming composition of the present application is applied to the lip makeup product formula system to further shorten the film-forming time.

[0043] In some embodiments, the mass ratio of phenyl silicone oil to film-forming agent can be (2.5-4):1, for example, 2.5:1, 3:1, 3.5:1, 4:1, or within the range of any two of the above ratios.

[0044] When the mass ratio of phenyl silicone oil to film former is within the above-mentioned suitable range, the film-forming composition of the present application is applied to the lip makeup product formula system to ensure rapid film formation and good ductility and moisturizing properties while maintaining a good film-forming effect. In this way, not only can the effect of not sticking to cups and not fading be achieved, but also the skin feel of lip makeup products can be improved.

[0045] In some embodiments, the film former may also include one or more of acrylic acid (ester) copolymers, VP / hexadecene copolymers, VP / eicosene copolymers, trimethylsiloxysilicate, polymethylsilsesquioxane, polypropylsilsesquioxane, acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymers, hydrogenated polycyclopentadiene, hydrogenated (styrene / methylstyrene / indene) copolymers, ethylene / propylene / styrene copolymers, butylene / ethylene / styrene copolymers, bis-hydroxyethoxypropyl polydimethylsiloxane / IPDI copolymer urethane, bis-PEG-15 polydimethylsiloxane / IPDI copolymer, bis-hydroxypropyl polydimethylsiloxane / SMDI copolymer, polyurethane, polyester, and glyceryl hydrogenated rosin ester.

[0046] 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 the range of any two of the above values.

[0047] In some embodiments, the viscosity of the film-forming aid at 60°C can also be 450mPa·s to 550mPa·s, for example, 450mPa·s, 480mPa·s, 500mPa·s, 520mPa·s, 550mPa·s, or within the range of any two of the above values.

[0048] Without intending to be limited by any theory or explanation, the film-forming aid selected from the above-mentioned types and having a specific viscosity acts on the film-forming system, which not only ensures the film-forming time and film-forming effect, but also makes the oil film reproducible and makes the film body three-dimensional and plump. Thus, the lip makeup product using the film-forming composition of the present application is applied to the lips, and after the lips come into contact with a smooth object (such as a glass, the back of the hand, etc.), the oil film on the surface is left on the surface of the smooth object. At this time, the oil phase remaining on the lips can quickly form a new oil film under the action of the film-forming aid, thereby achieving the reproduction of the oil film. In this way, even if the lips come into contact with the smooth object many times, the glossy effect can still be maintained. In this way, the lips can maintain a three-dimensional, plump and moist visual effect for a long time.

[0049] In some embodiments, the mass ratio of the film-forming aid to the film-forming agent can be (0.1-0.5):1, for example, 0.1:1, 0.2:1, 0.3:1, 0.4:1, 0.5:1, or within the range of any two of the above ratios.

[0050] In some embodiments, the mass ratio of the film-forming aid to the film-forming agent can also be (0.2-0.4):1, for example, 0.2:1, 0.25:1, 0.3:1, 0.35:1, 0.4:1, or within the range of any two of the above ratios.

[0051] When the mass ratio of the film-forming aid to the 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.

[0052] In some embodiments, the phytosterols or their derivatives may be selected from one or more of bis-behenyl alcohol / isostearyl alcohol / phytosteryl dimer linoleyl dimer linoleate, phytosterol / isostearyl alcohol / cetyl alcohol / stearyl alcohol / behenyl alcohol dimer linoleate, phytosteryl macadamia oleate, phytosteryl isostearate, phytosteryl oleate, phytosteryl isostearyl dimer linoleate, and bis-behenyl alcohol / phytosterol dimer linoleate.

[0063] The viscosity of hydrogenated polyisobutylene at 100° C. is 600 cst to 800 cst, for example, 600 cst, 620 cst, 650 cst, 680 cst, 700 cst, 720 cst, 750 cst, 780 cst, 800 cst, or within the range formed by any two of the above values.

[0064] According to the above embodiment, the viscosity of each component of the phenyl silicone oil, the film-forming aid and the film-forming agent is within a suitable range, so that the phenyl silicone oil, the film-forming aid and the film-forming agent have a suitable viscosity, which is conducive to further improving the film-forming effect of the film-forming composition.

[0104] The composition and related parameters of the film-forming composition were adjusted according to Table 1 to prepare lipsticks of Comparative Examples 1 to 6. The preparation process of the lipsticks of Comparative Examples 1 to 6 was the same as that of Example 1.

[0105] Test Section

[0106] (1) Cupping test

[0107] a. Smooth skin surface cup test

[0108] Apply lipstick paste to the subject's lips and immediately start a stopwatch to start timing. After 1 minute, gently touch the lips with lipstick to the arm skin, then observe the marks on the skin and assess the degree of cup staining.

[0109] b. Glass surface cupping test

[0110] Apply lipstick paste to the subject's lips and immediately start a stopwatch to start timing. After 1 minute, use a clear and clean glass cup to gently press the lips, then observe the marks on the cup and evaluate the degree of cup staining.

[0111] (2) Film formation time test

[0112] After the lipstick paste is evenly applied on the lips of the test subject, a stopwatch is immediately started to time. For each lipstick in the embodiment or the comparison group, three parallel experiments are designed, and each experiment is tested at a specific time point. The specific operation is:

[0113] In the first parallel experiment, 10 seconds after the start of the timing, the lips with lipstick were gently touched to the arm skin to observe whether there was any color powder residue on the skin surface. The second parallel experiment was carried out at 20 seconds. The third parallel experiment was carried out at 1 minute.

[0114] Through the above operation, the residual color powder after the lipstick on the lower lip contacts the arm skin at each time point is recorded. The shortest time when no color powder remains on the skin surface is taken as the film-forming time of the lipstick.

[0115] (3) Reproduction test

[0116] After applying the lipstick evenly on the lips, start the stopwatch immediately and stop the timer after 1 minute. Then gently touch the lips with lipstick to the skin of the arm to observe whether there is any color powder remaining on the skin surface. If there is no color powder remaining on the skin surface, gently touch the lips with lipstick to the skin of the arm again after 1 minute to observe whether there is any color powder remaining on the skin surface. Repeat this 3 times. If there is no color powder remaining on the skin surface, the lipstick is reproducible.

[0117] The test results of each embodiment and comparative example are shown in Table 2.

[0121] In Table 1, “√” may indicate that the corresponding substance is added, and “ / ” may indicate that the corresponding substance is not added or the corresponding parameter is not tested.

[0122] Table 2

[0123]

[0124] In Table 2, "no cup sticking" may indicate that no cup sticking occurs in both the smooth skin surface cup sticking test and the glass surface cup sticking test. "Cup sticking" may indicate that cup sticking occurs in both the smooth skin surface cup sticking test and the glass surface cup sticking test.

[0125] From Table 1 and Table 2, it can be found that the film-forming composition of the present application has a specific composition, and the viscosity and mass ratio of the phenyl silicone oil and the film-forming agent are within a specific range. When applied to a lipstick system, it can effectively shorten the film-forming time to within 1 minute, and achieve a better film-forming effect, so that the lipstick does not stick to the cup or fade.

[0126] In addition, it can be seen from Examples 1 to 8 that 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 the phenyl silicone oil to the film-forming agent are within an appropriate range, the film-forming time can be further shortened. It can be seen from Examples 1 to 8, Examples 9 to 16, and Examples 17 to 18 that adding an appropriate amount of a film-forming aid with an appropriate viscosity to the film-forming composition can make the lipstick reproducible while ensuring the film-forming time and film-forming effect.

[0127] In contrast, the viscosity of the phenyl silicone oil in Comparative Examples 1 to 2 is not within the scope of the present application, the viscosity of the film-forming agent in Comparative Examples 3 to 4 is not within the scope of the present application, and the mass ratio of the phenyl silicone oil to the film-forming agent in Comparative Examples 5 to 6 is not within the scope of the present application. Therefore, Comparative Examples 1 to 6 not only have a longer film-forming time, but also have a film-forming effect that is far inferior to that of Examples 1 to 18, and all of them have a cup-sticking phenomenon in the cup-sticking test. For example, see Figure 1 The lipstick of Example 1 was applied to the lips for 1 minute, and after contacting the arm skin, only a colorless oil film was left on the arm skin surface. However, the lipstick of Comparative Example 2 was applied to the lips for 1 minute, and after contacting the arm skin, toner remained on the arm skin surface, forming an obvious colored lip print.

[0128] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
