Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cosmetics, and particularly relates to a film-forming composition and a lip cosmetic product comprising the same. BACKGROUND

[0002] Lip cosmetic products such as lipsticks are one of important cosmetics, which are mainly applied on lips to increase the color of lips or change the color of lips. The raw materials of the lip cosmetic products can mainly include colorants, fillers, waxes, oils, pearl agents, fragrances, and preservatives, etc. The colorants containing pigments or dyes are dispersed in a uniform carrier formed by waxes and other oil components, so as to make the lip cosmetic products present different color tones.

[0003] The lip cosmetic products can be generally divided into glossy lip cosmetic products and matte lip cosmetic products according to their glossiness. Although the existing glossy lip cosmetic products can present a glossy effect, the colorants (such as color powder, etc.) in the glossy lip cosmetic products are soluble with the oil components. When the lips with the glossy lip cosmetic products are contacted with smooth objects (such as a glass cup, a back of a hand, etc.), the colorants in the cosmetic products are easily left on the surface of the smooth objects together with the oil components, resulting in cup-staining, color-falling, and the like. SUMMARY

[0004] To solve the above problems, the present application provides a film-forming composition and a lip cosmetic product comprising the same. The film-forming composition is applied in the formulation system of the lip cosmetic product, can quickly form an oil film, and has a good film-forming effect, thereby being beneficial to reduce the cup-staining, color-falling, and the like of the lip cosmetic product.

[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 exemplary embodiments are illustrated more specifically in the following description. In many places throughout the application, guidance is provided by a series of embodiments, which can be used in various combinations. In each instance, the enumeration is only representative of a group, and should not be interpreted as exhaustive.

[0030] As described in the background, the colorant (e.g. color powder, etc.) in the lip gloss product is soluble with the oil component, and when the lip coated with the lip gloss product is in contact with a smooth object (e.g. glass cup, back of hand, etc.), the colorant is easy to stay on the surface of the smooth object together with the oil component, resulting in cup staining, color dropping, etc.

[0031] In view of this, the inventors have made in-depth research and a large number of experiments, and provide a film-forming composition and a lip cosmetic product comprising the same.

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

[0033] The phenyl silicone oil includes two or more of diphenyl dimethicone, trimethyl pentaphenyl trisiloxane, phenyl trimethyl siloxane, and trimethyl siloxane phenyl dimethicone. 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 within a range defined by any two of the aforementioned 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 within a range defined by any two of the aforementioned values.

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

[0036] In the embodiments of the present application, the viscosity of each material has the meaning known in the art and can be determined by devices and methods known in the art. For example, the viscosity can be determined according to the test standard GB / T 265-1988.

[0037] In the embodiments of the present application, the viscosity of the phenyl silicone oil can be regulated in various ways. For example, the viscosity of the phenyl silicone oil can be regulated by regulating 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, and the like, so that the viscosity of the phenyl silicone oil satisfies the aforementioned range. Those skilled in the art can select a suitable regulation method according to the needs, which is not limited in the present application.

[0038] In the embodiments of the present application, the viscosity of the film-forming agent can be regulated in various ways. For example, the viscosity of the film-forming agent can be regulated by regulating 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, and the like, so that the viscosity of the film-forming agent satisfies the aforementioned range. Those skilled in the art can select a suitable regulation method according to the needs, which is not limited in the present application.

[0039] Without intending to be bound 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 in the above suitable range, which can interact to form an oil film when applied to the lip makeup product formulation system, and has 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 persistent and stable high-gloss oil film on the surface, and the film-forming time is within 1 minute. In this way, when the lips come into contact with a smooth object (such as a glass cup, the back of a hand, etc.), only an oil film will be left on the surface of the object, and the colorant in the product will not be transferred to the surface of the object with the oil film, thereby achieving the effects of not staining the cup and not discoloring.

[0040] In some embodiments, the viscosity of the phenyl silicone oil at 25°C can be 150 mPa s to 350 mPa s, for example, 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 a range formed by any two of the above values.

[0041] In some embodiments, the viscosity of the film-forming agent at 75°C can be 1800 mPa s to 2200 mPa s, for example, can be 1800 mPa s, 1900 mPa s, 2000 mPa s, 2100 mPa s, 2200 mPa s, or within a range formed by any two of the above values.

[0042] Without intending to be bound 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 applied to the lip makeup product formulation system can further shorten the film-forming time.

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

[0044] When the mass ratio of the phenyl silicone oil and the film-forming agent is in the above suitable range, the film-forming composition of the present application applied to the lip makeup product formulation system can ensure that the film-forming is quickly completed, and has good extensibility and moisturizing degree on the premise of maintaining good film-forming effect. In this way, not only the effects of not staining the cup and not discoloring can be achieved, but also the skin feel of the lip makeup product can be improved.

[0045] In some embodiments, the film-forming agent can further include one or more of acrylic copolymer, VP / hexadecene copolymer, VP / eicosene copolymer, trimethyl siloxy silicate, polymethylsilsesquioxane, polypropylsilsesquioxane, acrylic / polytrimethylsiloxane methacrylate copolymer, hydrogenated polycyclopentadiene, hydrogenated (styrene / methylstyrene / indene) copolymer, ethylene / propylene / styrene copolymer, butene / ethylene / styrene copolymer, bis-hydroxyethoxypropyl dimethicone / IPDI copolymer urethane, bis-PEG-15 dimethicone / IPDI copolymer, bis-hydroxypropyl dimethicone / SMDI copolymer, polyurethane, polyester, glyceryl hydrogenated rosin acid ester.

[0046] In some embodiments, the film-forming composition can further include a film- forming aid. The film-forming aid can be phytosterols or derivatives thereof, and the film- forming aid can have a viscosity of 300 mPa-s to 700 mPa-s at 60°C, for example, 300 mPa-s, 400 mPa-s, 500 mPa-s, 600 mPa-s, 700 mPa-s, or within a range between any two of the aforementioned values.

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

[0048] Without being bound by any theory or explanation, the film-forming aid selected from the aforementioned types and having a specific viscosity acts on the film-forming system, not only ensuring the film-forming time and film-forming effect, but also making the oil film reproducible and the film body three-dimensional and plump. Thus, when the lip makeup product using the film-forming composition of the present application is applied to the lips, and the lips are in contact with a smooth object (e.g., a glass cup, a back of a 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 rapidly 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 are in contact with the smooth object multiple times, the gloss effect can be maintained. In this way, the lips can maintain a three-dimensional and plump 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 a range between any two of the aforementioned values.

[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, can be 0.2: 1, 0.25: 1, 0.3: 1, 0.35: 1, 0.4: 1, or within a range between any two of the above values.

[0051] When the mass ratio of the film forming aid to the film forming agent is within the above suitable range, the reproducibility of the oil film can be more durable, and the three-dimensional fullness of the film body can be optimized.

[0052] In some embodiments, the phytosteryl or its derivative can be selected from one or more of the following: bis-behenyl / isostearyl / phytosteryl dimer dilinoleate, phytosteryl / isostearyl / cetyl / stearyl / behenyl dimer dilinoleate, phytosteryl macadamia nut oilate, phytosteryl isostearate, phytosteryl oleate, phytosteryl isostearyl dimer dilinoleate, bis-behenyl / phytosteryl dimer dilinoleate.

[0064] According to the above embodiments, the viscosity of each component of the phenyl silicone oil, the film forming aid, and the film forming agent is within a suitable range, which can result in a suitable viscosity of the phenyl silicone oil, the film forming aid, and the film forming agent.

[0105] Test Part

[0106] (1) Cupping Test

[0107] a. Smooth skin surface cupping test

[0108] The lipstick paste is applied to the lips of the subject, and immediately a stopwatch is started to begin timing. After 1 min, the lips with the lipstick are gently touched to the skin of the arm, and then the traces on the skin are observed to evaluate the degree of cupping.

[0109] b. Glass surface cupping test

[0110] The lipstick paste is applied to the lips of the subject, and immediately a stopwatch is started to begin timing. After 1 min, a clean transparent glass cup is used to gently press the lips, and then the traces on the cup are observed to evaluate the degree of cupping.

[0111] (2) Film formation time test

[0112] After the lipstick paste is evenly applied to the lips of the subject, a stopwatch is immediately started to begin timing. For each example or comparative example of lipstick, 3 parallel experiments are designed respectively, and each experiment is tested at a specific time point. The specific operation is as follows:

[0113] The first parallel experiment gently touches the lips with the lipstick to the skin of the arm at 10 s after the timing starts, and the presence or absence of color powder residues on the skin surface is observed. The second parallel experiment performs the same test at 20 s. The third parallel experiment performs the same test at 1 min.

[0114] Through the above operation, the color powder residues after the lips with the lipstick are contacted with the skin of the arm at each time point are recorded. The shortest time without color powder residues on the skin surface is taken as the film formation time of the lipstick.

[0115] (3) Reproducibility test

[0116] After the lipstick paste is evenly applied to the lips, a stopwatch is immediately started to begin timing, and the timing is stopped at 1 min. The lips with the lipstick are gently touched to the skin of the arm, and the presence or absence of color powder residues on the skin surface is observed. If there are no color powder residues on the skin surface, the lips with the lipstick are gently touched to the skin of the arm again after 1 min, and the presence or absence of color powder residues on the skin surface is observed. This is repeated 3 times. If there are no color powder residues on the skin surface all the time, the lipstick has reproducibility.

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

[0118]

[0120]

[0121] In Table 1, "√" can represent that the corresponding substance is added, and " / " can represent that the corresponding substance is not added or the corresponding parameter is not tested.

[0122] Table 2

[0123]

[0124] In Table 2, "no cupping" can represent that no cupping phenomenon occurs in both the smooth skin surface cupping test and the glass surface cupping test. "Cupping" can represent that cupping phenomenon occurs in both the smooth skin surface cupping test and the glass surface cupping test.

[0125] It can be found from Table 1 and Table 2 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, which can effectively shorten the film-forming time when applied to a lipstick system, so that the film-forming time is within 1 min, and a good film-forming effect is achieved, so that the lipstick does not cup and does not discolor.

[0126] In addition, it can be seen from Examples 1-8 that when the viscosity of the phenyl silicone oil, the viscosity of the film-forming agent, and the mass ratio of the phenyl silicone oil and the film-forming agent in the film-forming composition are within a suitable range, the film-forming time can be further shortened. It can be seen from Examples 1-8, Examples 9-16, and Examples 17-18 that the addition of an appropriate amount of a film-forming aid with suitable viscosity in 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 1-2 is not within the range of the present application, the viscosity of the film-forming agent in Comparative Examples 3-4 is not within the range of the present application, and the mass ratio of the phenyl silicone oil and the film-forming agent in Comparative Examples 5-6 is not within the range of the present application. Thus, Comparative Examples 1-6 not only have a long film-forming time, but also have a film-forming effect far inferior to Examples 1-18, and all produce cupping phenomenon in the cupping test. For example, referring to Figure 1 , the lipstick of Example 1 is applied to the lips for 1 min, and after contacting with the arm skin, only a colorless oil film is left on the surface of the arm skin. However, the lipstick of Comparative Example 2 is applied to the lips for 1 min, and after contacting with the arm skin, there is color powder residue on the surface of the arm skin, forming a clear colored lip print.

[0128] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements are all encompassed within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
