Description

Technical Field

[0001] This application belongs to the field of cosmetic technology, specifically relating to an oil-in-water type glossy lip cosmetic and its preparation method. Background Technology

[0002] In recent years, lip glosses and lip tints have made breakthroughs in both product texture and efficacy due to their pursuit of refined sensory experience and deep integration of biotechnology and natural ingredients.

[0003] Oil-based lip glosses and lip stains, while providing high shine, lack the synergistic effect of water-based ingredients and cannot contain currently popular moisturizing actives, resulting in weaker moisturizing longevity and a less refreshing feel. After use, lips are prone to dryness, becoming dry and rough due to lack of moisture; at the same time, a tight feeling may occur, as if the lips are covered by a tight film.

[0004] Water-in-oil lip glosses and lip stains, due to their limited oil content (usually below 25%), rely primarily on a small amount of oil in the water-based base for shine, making it difficult to achieve high gloss and full luster. Furthermore, due to the limited oil content, their water-locking ability is also limited, making them only suitable for basic daily moisturizing. In addition, because the outer phase is water-based and hydrophilic, they are prone to turning white upon contact with water, severely affecting the appearance of lip makeup.

[0005] In theory, water-in-oil systems can incorporate water-based components to provide hydration while also containing a high oil content to provide gloss. However, during the actual product development process, the applicant discovered that increasing gloss requires maximizing the oil content in the formula, but increasing the oil content in water-in-oil systems poses a challenge to emulsification stability. Furthermore, compared to all-oil formulations, the aqueous phase in water-in-oil formulations interferes with the film-forming properties and non-stick durability of the oil phase, making it very difficult to achieve a non-stick effect. While increasing the amount of oil-based film-forming agents can ensure film formation and non-stick durability, excessive oil-based agents, in turn, exacerbate the difficulty of emulsification. Therefore, it is difficult to obtain a product that offers both moisturizing effects and gloss and non-stick properties comparable to all-oil formulations. Summary of the Invention

[0006] To address the aforementioned issues, this application provides an oil-in-water type glossy lip cosmetic that incorporates oil-in-water emulsification technology into the traditional lip gloss system. This overcomes the shortcomings of both all-oil and water-in-oil systems, and also solves the challenges posed by oil-in-water emulsification to system stability and non-stickiness. Ultimately, this results in a lip cosmetic that demonstrates significant superior performance in terms of moisturizing, gloss, and non-stickiness.

[0007] The first aspect of this application provides an oil-in-water type glossy lip cosmetic, comprising, by weight percentage: 75%–90% oil phase and 10%–25% water phase; wherein, the oil phase comprises: High-gloss oil composition: The high-gloss oil composition has a mass percentage of 45%~50% in the cosmetic; the high-gloss oil composition is a composition of phenyl silicone oil and hydrogenated polyisobutylene, wherein the phenyl silicone oil contains at least trimethylpentaphenyltrisiloxane and trimethylsiloxane-oxyphenyl polydimethylsiloxane, and the sum of the mass percentages of trimethylpentaphenyltrisiloxane and trimethylsiloxane-oxyphenyl polydimethylsiloxane in the cosmetic is at least 25%; Emulsifying composition: The emulsifying composition has a mass percentage of 4.5% to 6.5% in the cosmetic; the emulsifying composition comprises isodecyl neopentanoate and lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane, and the mass ratio of isodecyl neopentanoate to lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane is (4~6):1; Film-forming composition: The film-forming composition has a mass percentage of 8%~12% in the cosmetic; the film-forming composition contains VP / hexadecene copolymer and acrylic (ester) copolymer, wherein the mass ratio of VP / hexadecene copolymer to acrylic (ester) copolymer is (3.5~4.5):1, and the viscosity of VP / hexadecene copolymer and acrylic (ester) copolymer at 25°C is 37500cP~47500cP and 300cP~360cP, respectively.

[0008] Compared to existing technologies, the oil-in-water glossy lip cosmetic provided in this application uses oil as the continuous phase. Through the formation of a uniform glossy film on the lip surface by oily components with high refractive index, it produces a bright, mirror-like effect similar to that of all-oil formulas, satisfying consumers' demands for "glossy lips" and "glass lips." Simultaneously, the constructed oil-in-water system possesses the moisturizing properties and refreshing, watery feel lacking in all-oil formulas, and avoids the staining and whitening issues associated with water-in-oil glossy products. Of particular note is the synergistic effect of the two key components in the formulation of this application: (1) By using innovative emulsifying compositions, the emulsification stability of high-gloss oils and aqueous phases during preparation and the long-term storage stability after preparation are achieved, so that the product can obtain extremely high gloss while ensuring stability.

[0009] Increasing the content of phenyl silicone oil and hydrogenated polyisobutylene with high refractive index in products can effectively improve product gloss. However, both of these types of oils are difficult to be compatible with water. As the content increases, the difficulty of emulsification increases, which is manifested in the difficulty of emulsification or the poor stability of the emulsion formed. In environments with slightly higher storage temperatures or drastic temperature changes, it is easy to lose its emulsified structure.

[0010] The formulation of this application uses an emulsified composition of isodecyl neopentanoate and lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane in a mass ratio of (4~6):1. This emulsifies the poorly compatible phenyl silicone oil with water to form a water-in-oil structure with good storage stability. This allows the total content of phenyl silicone oil and hydrogenated polyisobutylene in the formulation to be as high as 45%~50%, and the total oil phase content to be as high as 75%~90%, achieving high brightness comparable to all-oil products.

[0011] (2) By combining an innovative film-forming composition with phenyl silicone oil that has excellent colorant isolation effect, a thin and stable color-locking film is formed, giving the product excellent film-forming properties and non-stick cup durability.

[0012] Film-forming agents are key ingredients in achieving a non-transferable effect in lip cosmetics. When a lip product is applied to the lips, the solvent evaporates, and the film-forming agent forms a uniform thin film on the lip surface. This film locks in the colorant, preventing the lip color from contacting external objects, and also has waterproof and oil-proof properties, effectively preventing lip makeup from staining objects it comes into contact with—this is the non-transferable effect. In this application's formulation, hydrogenated polyisobutylene, in addition to enhancing gloss, can itself form a film on the skin surface. In some all-oil formulations, using only phenyl silicone oil and hydrogenated polyisobutylene is sufficient to achieve basic film-forming and non-transferable effects. However, compared to all-oil formulations, the added aqueous phase in the water-in-oil system of this application interferes with the film-forming effect and the durability of the non-transferable effect. If the film-forming effect of the water-in-oil formulation is ensured by adding an oily film-forming agent, excessive oily film-forming agents, in turn, affect the stability of the water-in-oil emulsion. Therefore, the non-transferable effect of water-in-oil lip products is often inferior to that of all-oil formulations.

[0013] This application uses a composition comprising a VP / hexadecene copolymer and an acrylic (ester) copolymer as a film-forming agent. Although VP / hexadecene copolymer and acrylic (ester) copolymer are two conventional film-forming agents in the art, they have different viscosities at different degrees of polymerization, thus affecting their film-forming effect. The applicant has discovered that by selecting a VP / hexadecene copolymer with a viscosity of 37500 cP to 47500 cP and an acrylic (ester) copolymer with a viscosity of 300 cP to 360 cP, and composing the film-forming composition at a mass ratio of (3.5 to 4.5):1, and adding sufficient amounts of trimethylpentaphenyltrisiloxane and trimethylsiloxane-oxyphenyl polydimethylsiloxane, which have excellent colorant isolating effects, unexpectedly excellent non-stick properties can be obtained. The VP / hexadecene copolymer film is soft and dense, while the acrylic (ester) copolymer film has better hardness and abrasion resistance; the film formed by the synergistic effect of the two has both a soft and lightweight feel and high stability. Compared to other oils, trimethylpentaphenyltrisiloxane and trimethylsilaneoxyphenyl polydimethylsiloxane not only have higher brightness but also a stronger effect in isolating colorants. A film-forming composition of VP / hexadecene copolymer and acrylate copolymer, together with trimethylpentaphenyltrisiloxane and trimethylsilaneoxyphenyl polydimethylsiloxane oils with a total content of 25% or more, forms a color-locking film, which significantly improves the film-forming properties and the durability of the non-stick effect of the product.

[0014] Optionally, in the high-gloss oil composition provided in this application, the mass ratio of phenyl silicone oil to hydrogenated polyisobutylene is (4~8):1.

[0015] Optionally, in the water-in-oil glossy lip cosmetic provided in this application, the phenyl silicone oil further comprises diphenyl polydimethylsiloxane and / or phenyl polytrimethylsiloxane.

[0016] Optionally, in the water-in-oil glossy lip cosmetic provided in this application, the film-forming component further includes glyceryl hydrogenated pinoresinate; the mass ratio of VP / hexadecene copolymer, acrylic (ester) copolymer, and glyceryl hydrogenated pinoresinate is (3.5~4.5):1:2. Glyceryl hydrogenated pinoresinate alone has weaker film-forming ability than VP / hexadecene copolymer and acrylic (ester) copolymer, but it also has certain thickening and emulsifying effects. The further addition of glyceryl hydrogenated pinoresinate to the formulation of this application assists the main film-forming agents VP / hexadecene copolymer and acrylic (ester) copolymer in film formation, which can adjust the product texture, making the film layer more moisturizing and improving lip smoothness.

[0017] Optionally, in the water-in-oil glossy lip cosmetic provided in this application, the oil phase further includes a wax composition, the wax composition comprising 6% to 8% by mass in the cosmetic, and the wax composition comprising one or more of VP / eicosene copolymer, dextrin palmitate, and synthetic wax. The wax content also affects the emulsion stability and skin feel of the water-in-oil glossy lip cosmetic of this application. Excessive wax content will cause the emulsion to undergo significant changes in state during temperature variations in the preparation process, which is not conducive to the formation of a stable emulsion; insufficient wax content will result in a product with an overly oily and not refreshing finish.

[0018] Optionally, in the water-in-oil glossy lip cosmetic provided in this application, the oil phase may further include one or more of colorants, dispersants, thickeners, and oil-soluble preservatives.

[0019] Optionally, in the water-in-oil glossy lip cosmetic provided in this application, the aqueous phase includes one or more of deionized water, active ingredients, moisturizers, and water-soluble preservatives; wherein the mass percentage of deionized water in the cosmetic is 9% to 16%.

[0020] Optionally, in the water-in-oil glossy lip cosmetic provided in this application, the aqueous phase further includes one or more of active ingredients, moisturizers, and water-soluble preservatives.

[0021] Optionally, the oil-in-water type glossy lip cosmetics provided in this application include lip gloss or lip stain.

[0022] The second aspect of this application provides a method for preparing a water-in-oil glossy lip cosmetic, comprising the following steps: Preparing phase A: mixing a wax composition with a film-forming composition, melting at 80°C~90°C, dispersing evenly, adding a high-gloss oil composition, an emulsifying composition, a colorant, a dispersant, a thickener, and an oil-soluble preservative, and mixing evenly at 70°C~80°C to obtain phase A; Preparing phase B: mixing deionized water with a moisturizer, an active ingredient, and a water-soluble preservative evenly at 70°C~80°C to obtain phase B; Preparing the mixture: adding phase B to phase A, homogenizing at 5000rpm~6000rpm for 5min~20min; Filling: maintaining 70°C~80°C for filling, cooling, to obtain the water-in-oil glossy lip cosmetic.

[0029] 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.

[0030] In view of the aforementioned deficiencies in the prior art, this application provides an oil-in-water type glossy lip cosmetic and its preparation method, the prepared lip cosmetic having the excellent properties of high gloss, strong moisturizing and long-lasting non-stickiness.

[0031] The first aspect of this application provides an oil-in-water type glossy lip cosmetic, comprising, by weight percentage: 75%–90% oil phase and 10%–25% water phase; wherein the oil phase comprises: a high-gloss oil composition: the high-gloss oil composition comprises 45%–50% by weight in the cosmetic; the high-gloss oil composition is a composition of phenyl silicone oil and hydrogenated polyisobutylene, wherein the phenyl silicone oil comprises at least trimethylpentaphenyltrisiloxane and trimethylsiloxane-oxyphenyl polydimethylsiloxane, and the sum of the weight percentages of trimethylpentaphenyltrisiloxane and trimethylsiloxane-oxyphenyl polydimethylsiloxane in the cosmetic is at least 25%; an emulsifying composition: the emulsifying composition comprises 4.5%–6.5% by weight in the cosmetic; the emulsifying composition comprises a composition of isodecanyl pentanoate and lauryl PEG-10 tris(trimethoxy)silylethyl polydimethylsiloxane, wherein isodecanyl pentanoate and the lauryl PEG-10 The mass ratio of tri(trimethoxy)silyl ethyl polydimethylsiloxane is (4~6):1; the film-forming composition: the mass percentage of the film-forming composition in the cosmetic is 8%~12%; the film-forming composition contains VP / hexadecene copolymer and acrylic (ester) copolymer, the mass ratio of VP / hexadecene copolymer and acrylic (ester) copolymer is (3.5~4.5):1, and the viscosity of VP / hexadecene copolymer and acrylic (ester) copolymer at 25°C is 37500cP~47500cP and 300cP~360cP, respectively.

[0032] As an example, based on the total mass of water-in-oil glossy lip cosmetics, the mass content of the oil phase can be 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, or 90%.

[0033] As an example, based on the total mass of water-in-oil glossy lip cosmetics, the mass content of the aqueous phase can be 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, 21%, 22%, 23%, 24%, or 25%.

[0034] As an example, the high-gloss oil composition in cosmetics can be 45%, 45.5%, 46%, 46.5%, 47%, 47.5%, 48%, 48.5%, 49%, 49.5%, or 50% by weight.

[0035] As an example, the sum of the mass percentages of trimethylpentaphenyltrisiloxane and trimethylsiloxaneoxyphenylpolydimethylsiloxane in the cosmetic product may be 25%, 26%, 27%, 28%, 29%, 30%, 31%, 32%, 33%, 34%, or 35%.

[0036] As an example, the mass percentage of the emulsified composition in the cosmetic can be 4.5%, 4.8%, 5%, 5.2%, 5.5%, 5.8%, 6%, 6.2%, or 6.5%.

[0037] As an example, the mass ratios of isodecyl neopentanoate and lauryl PEG-10 tris(trimethoxy)silylethyl polydimethylsiloxane are 4:1, 4.1:1, 4.2:1, 4.3:1, 4.4:1, 4.5:1, 4.6:1, 4.7:1, 4.8:1, 4.9:1, 5.0:1, 5.2:1, 5.5:1, 5.8:1, 6:1, 6.2:1, 6.5:1, 6.8:1, 7:1, 8:1, 9:1, and 10:1.

[0038] As an example, the mass percentage of the film-forming composition in the cosmetic can be 8%, 9%, 10%, 11%, or 12%.

[0039] As an example, the mass ratio of the VP / hexadecene copolymer to the acrylate copolymer can be 3.5:1, 3.6:1, 3.7:1, 3.8:1, 3.9:1, 4.0:1, 4.1:1, 4.2:1, 4.3:1, 4.4:1, or 4.5:1.

[0040] As an example, the viscosity of the VP / hexadecene copolymer at 25°C can be 37500 cP, 38500 cP, 39500 cP, 40000 cP, 41500 cP, 42500 cP, 43500 cP, 44500 cP, 45500 cP, 46500 cP, or 47500 cP.

[0041] As an example, the viscosity of acrylate copolymers at 25°C can be 300 cP, 310 cP, 320 cP, 330 cP, 340 cP, 350 cP, or 360 cP.

[0042] By using the above-mentioned specific formulation of a high-gloss oil composition (specific phenyl silicone oil content ≥25%), a specific ratio of emulsifying composition (isodecyl neopentanoate and lauryl PEG-10 trisiloxane compounded at (4~6):1), and a specific viscosity and ratio of film-forming composition (VP / hexadecene copolymer and acrylic (ester) copolymer compounded at (3.5~4.5):1), the water-in-oil emulsification technology can be successfully integrated into the traditional lip gloss / lip stain system. This innovative combination works synergistically to ensure a high oil phase content (75%~90%) to achieve the high gloss of a full-oil system, while using the emulsifying composition to solve the stability problem of high content of difficult-to-emulsify oil and water phase; and through the synergistic film formation of the film-forming composition and high content of phenyl silicone oil, it effectively resists the interference of water phase on film-forming properties, thus achieving a non-stick effect comparable to or even surpassing the full-oil formula, while also possessing the water-like moisturizing advantages of the water-in-oil system, ultimately overcoming the traditional challenges of stability and non-stick performance of the water-in-oil system.

[0043] In some embodiments, the mass ratio of phenyl silicone oil to hydrogenated polyisobutylene in the high-gloss oil composition is (4~8):1.

[0044] As an example, the mass ratio of phenyl silicone oil to hydrogenated polyisobutylene can be 4:1, 4.5:1, 5:1, 5.5:1, 6:1, 6.5:1, 7:1, 7.5:1, or 8:1.

[0045] The mass ratio of phenyl silicone oil to hydrogenated polyisobutylene is controlled at (4~8):1. This not only ensures that the high-refractive-index phenyl silicone oil dominates, providing the system with a mirror-like full gloss, but also, with an appropriate amount of hydrogenated polyisobutylene as an excellent spreader and co-stabilizer, it can assist the phenyl silicone oil in uniform film formation and improve the skin feel. It can also work synergistically with the emulsion composition to ensure that the high-content oil and water phase form a stable water-in-oil structure. Thus, while achieving a gloss comparable to the whole oil system, it avoids the problem of poor emulsification stability caused by high oil content.

[0046] In some embodiments, the phenyl silicone oil also comprises diphenyl polydimethylsiloxane and / or phenyl polytrimethylsiloxane.

[0047] By combining different phenyl silicone oils, the skin feel, compatibility, and stability of the product can be further optimized while ensuring high gloss. Diphenyl polydimethylsiloxane and phenyl polytrimethylsiloxane also belong to the high refractive index phenyl silicone oil family and are effective supplements or partial substitutes for the main components such as trimethylpentaphenyltrisiloxane. Their introduction can adjust the viscosity and polarity of the entire high-gloss oil composition, making it more compatible with the emulsifying composition, film-forming composition, and other oil phase components. This helps to form a finer and more stable emulsion system, and synergistically contributes to the overall excellent performance of full gloss, smooth application, and long-lasting moisturization in the final makeup effect.

[0048] In some embodiments, the film-forming composition further comprises glyceryl hydrogenated rosinate.

[0049] In some embodiments, the mass ratio of VP / hexadecene copolymer, acrylate copolymer and glyceryl hydrogenated rosinate is (3.5~4.5):1:2.

[0050] As an example, the mass ratio of VP / hexadecene copolymer, acrylate copolymer and glyceryl hydrogenated rosinate can be 3.5:1:2, 3.8:1:2, 3.9:1:2, 4:1:2, 4.1:1:2, 4.2:1:2, 4.3:1:2, 4.4:1:2, or 4.5:1:2.

[0051] Glyceryl hydrogenated rosinate, a natural derivative ester with plasticizing and film-forming properties, can effectively regulate the flexibility and adhesion of polymer films formed by VP / hexadecene copolymers and acrylic (ester) copolymers, making the final color-locking film thinner, more adherent, and less prone to cracking. This directly enhances the durability of the non-stick effect. At the same time, its own moisturizing properties, combined with the water phase in the oil-in-water system, further enhance the long-lasting moisturizing effect on the lips, allowing the product to achieve excellent non-stick effects while avoiding the dryness that may result from a full-oil formula.

[0052] In some embodiments, the oil phase further comprises a wax composition, wherein the wax composition comprises 6% to 8% by mass in the cosmetic, and the wax composition comprises one or more of VP / eicosene copolymer, dextrin palmitate, and synthetic wax.

[0053] As an example, the wax composition in cosmetics can be 6%, 6.5%, 7%, 7.5%, or 8% by mass.

[0054] The wax composition with the above-mentioned specific mass percentage content and ingredients can construct a flexible network structure in the system, significantly enhancing the stability of the water-in-oil emulsion and preventing oil-water separation during high-temperature storage or transportation. At the same time, they can moderately enhance the structural strength of the system, giving the product a rich cream texture, avoiding excessive greasiness caused by high oil content, making the makeup effect more sophisticated in addition to high gloss, and indirectly assisting in achieving the non-sticky effect by reinforcing the overall structure and working synergistically with the film-forming agent.

[0055] In some embodiments, the oil phase also includes one or more of colorants, dispersants, thickeners, and oil-soluble preservatives.

[0056] As an example, an oil-soluble preservative may be at least one of ethylhexylglycerin and p-hydroxyacetophenone.

[0057] In some embodiments, the content of oil-soluble preservatives in water-in-oil glossy lip cosmetics is 0% to 1.5%.

[0058] As an example, the content of oil-soluble preservatives in water-in-oil glossy lip cosmetics can be 0%, 0.1%, 0.2%, 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, and 1.5%.

[0059] As an example, the content of colorant in water-in-oil glossy lip cosmetics can be 1.2% to 3% (e.g., 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3%). The colorant can be any colorant commonly used in cosmetics, including but not limited to: CI73360, CI19140, CI15850, CI77499, CI77491, CI77891, CI77492, etc.

[0060] As an example, the content of dispersant in water-in-oil glossy lip cosmetics can be 8-12%. The dispersant can be any composition that is commonly used in cosmetics and has a dispersing effect, including but not limited to: isododecane, polydimethylsiloxane, isohexadecane, propylene glycol dibenzoate, diisostearyl malate, etc.

[0061] As an example, the content of thickener in water-in-oil glossy lip cosmetics can be 0-2%. The thickener can be any type of thickener commonly used in cosmetics or any combination of thickening agents, including but not limited to: distearate, lithium dimethylammonium montmorillonite, silachlor, hydropyrite, etc.

[0062] Colorants impart vibrant color to the lips; dispersants effectively prevent pigment sedimentation, ensuring even color distribution and pure gloss; thickeners work synergistically with the wax composition to further optimize the system structure, enhance emulsion stability, and improve the luxurious feel during application; while oil-soluble preservatives precisely target the oil phase for preservation, ensuring the hygiene and safety of high-oil-content formulations.

[0063] In some embodiments, the aqueous phase comprises deionized water, which has a mass percentage of 9% to 16% in the cosmetic.

[0064] As an example, the mass percentage of deionized water in cosmetics can be 9%, 9.5%, 10%, 10.5%, 11%, 11.5%, 12%, 12.5%, 13%, 13.5%, 14%, 14.5%, 15%, 15.5%, or 16%.

[0065] Limiting the deionized water content in the aqueous phase to 9%~16% achieves a "water-in-oil" structure and balances moisturizing, stability, and makeup effect. This amount of deionized water is sufficient to dissolve water-soluble moisturizers and active ingredients, providing lips with a long-lasting hydration lacking in all-oil formulas, thus overcoming their drying properties. Simultaneously, this aqueous phase ratio ensures adequate hydration while avoiding excessive water that could disrupt the continuity of the high-gloss oil phase. This allows the emulsion composition to effectively encapsulate the oil phase, maintaining long-term system stability and preventing interference with film formation and non-stickiness due to excessive water. Ultimately, this ensures the product's superior performance in moisturizing, shine, and staying power.

[0066] In some embodiments, the aqueous phase also includes one or more of an active ingredient, a humectant, and a water-soluble preservative.

[0067] In some embodiments, the water-soluble preservative is present in the water-in-oil glossy lip cosmetic at a concentration of 0.3% to 1.5%.

[0068] As an example, the content of water-soluble preservatives in water-in-oil glossy lip cosmetics can be 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, and 1.5%.

[0069] As an example, water-soluble preservatives include at least one of 1,2-hexanediol and phenoxyethanol.

[0070] As an example, the content of active ingredients in water-in-oil glossy lip cosmetics can be 0.5% to 2%; the active ingredients can be selected from one or a combination of several of the following: Myrothamnus flabellifolia leaf / stem extract, acetylated sodium hyaluronate, sodium hyaluronate, sodium hyaluronate crosspolymer, hydrolyzed sodium hyaluronate, peony seed oil, peony root extract, squalane, aloe vera leaf juice, and collagen.

[0071] As an example, the content of moisturizer in water-in-oil glossy lip cosmetics can be 0-8%.

[0072] As an example, the total content of oil-soluble and water-soluble preservatives in water-in-oil glossy lip cosmetics can be 0.3% to 3% (e.g., 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1.0%, 1.1%, 1.2%, 1.3%, 1.4%, 1.5%, 1.6%, 1.7%, 1.8%, 1.9%, 2.0%, 2.1%, 2.2%, 2.3%, 2.4%, 2.5%, 2.6%, 2.7%, 2.8%, 2.9%, 3.0%). Various oil-soluble and water-soluble preservatives commonly used in cosmetics can be selected, or compositions with preservative effects can be selected, including but not limited to: ethylhexylglycerin, 1,2-hexanediol, p-hydroxyacetophenone, phenoxyethanol, etc.

[0073] The aforementioned water-soluble ingredients (such as moisturizers like sodium hyaluronate and active ingredients like plant extracts) can be directly carried and precisely delivered to the lips by the aqueous phase, effectively solving the fundamental shortcoming of the all-oil system's inability to deeply hydrate, thus providing a long-lasting moisturizing feel. At the same time, the addition of water-soluble preservatives specifically protects the aqueous phase from microbial contamination, working synergistically with oil-soluble preservatives to build a complete preservative system, ensuring that the product has excellent shine and non-stick properties while also providing safe and stable moisturizing and nourishing functions.

[0074] In some implementations, glossy lip cosmetics include lip gloss or lip stain.

[0075] The second aspect of this application provides a method for preparing the water-in-oil glossy lip cosmetic described in the first aspect, comprising the following steps: Preparation of Phase A: The wax composition and the film-forming composition are mixed and melted at 80℃~90℃ (e.g., 80℃, 85℃, 90℃), and dispersed evenly. A high-gloss oil composition, an emulsifying composition, a colorant, a dispersant, a thickener, and an oil-soluble preservative are added and mixed evenly at 70℃~80℃ (e.g., 70℃, 75℃, 80℃) to obtain Phase A; Preparation of phase B: Deionized water, humectant, active ingredient, and water-soluble preservative are mixed evenly at 70℃~80℃ (e.g., 70℃, 75℃, 80℃) to obtain phase B; Preparation of the mixture: Add phase B to phase A and homogenize at a speed of 5000 rpm to 6000 rpm (e.g., 5000 rpm, 5500 rpm, 6000 rpm) for 5 min to 20 min; Filling: Maintain a filling temperature of 70℃~80℃ (e.g., 70℃, 75℃, 80℃), then cool to obtain an oil-in-water type glossy lip cosmetic.

[0076] Phase separation preparation (phases A and B) and maintaining the temperature at 70℃~80℃ ensures complete melting of the wax and film-forming agent, and full compatibility of each component, laying the foundation for the formation of a stable system. Adding phase B (aqueous phase) to phase A (oil phase) and combining it with high-speed homogenization (5000~6000rpm) can form a delicate and stable water-in-oil emulsion. This ensures that the high oil content can tightly encapsulate the aqueous phase, reducing the difficulty of emulsification. The process of maintaining 70℃~80℃ for filling and then cooling avoids the problems of air bubbles being introduced and affecting gloss when filling at low temperatures. The cooling process also promotes perfect film formation of the film-forming agent, ultimately ensuring that the product simultaneously achieves excellent performance in terms of mirror gloss, long-lasting non-stick properties, and deep moisturizing.

See Table 15 for details. Table 15

[0107] The preparation steps of the lip cosmetic product in Comparative Example 10 are the same as those in Example 1.

[0108] Test section I. Stability Testing 1. Emulsion stability test In the preparation process of the lip cosmetics in Examples 1-5 and Comparative Examples 1-7, after the preparation of the mixture and before filling, it was observed whether the mixture formed a uniform and stable water-in-oil emulsion: without oil-water separation, water seepage, or gloss.

[0109] 2. Storage stability test The lip cosmetics prepared in Examples 1-5 and Comparative Examples 1-7 were placed in environments of 4°C (low temperature) and 45°C (high temperature) and stored for 6 months to observe whether the material remained uniform and stable.

[0110] The stability test results of Examples 1-5 and Comparative Examples 1-7 are shown in Table 16: Table 16 Stability Test Results

[0111] The stability test results show that: Examples 1-5 used an emulsifying composition consisting of isodecyl neopentanoate and lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane in a mass ratio of (4-6):1, and a film-forming composition consisting of VP / hexadecene copolymer with a viscosity of 37500 cP-47500 cP and acrylic (ester) copolymer with a viscosity of 300 cP-360 cP in a mass ratio of (3.5-4.5):1. Combined with more than 25% of trimethylpentaphenyltrisiloxane and trimethylsiloxaneoxyphenyl polydimethylsiloxane, which have excellent isolating colorant effects, the difficult-to-complicate high-gloss oil composition was successfully emulsified with the aqueous phase to form a water-in-oil structure. With the content of high-gloss high-quality composition as high as 45-50% and the total oil phase content as high as 75-90% in the formulation, not only was a good oil-water emulsification effect achieved in the preparation process, but it also had good storage stability under high and low temperature environments.

[0112] In contrast, Comparative Examples 1-3 did not use the emulsifying composition defined in this application: using only isodecyl pentanoate or lauryl PEG-10 tris(trimethoxy)silylethyl polydimethylsiloxane alone, or replacing isodecyl pentanoate and lauryl PEG-10 tris(trimethoxy)silylethyl polydimethylsiloxane in equal amounts with two other commonly used emulsifiers for constructing water-in-oil systems, none of these methods could successfully emulsify the high-content, high-gloss oil system of this application with the aqueous phase into a homogeneous mixture, resulting in obvious oil-water separation during preparation. This indicates that the emulsifying composition of isodecyl pentanoate and lauryl PEG-10 tris(trimethoxy)silylethyl polydimethylsiloxane in a mass ratio of (4-6):1 as defined in this application is not a conventional choice in the art, but it has outstanding emulsifying effects in the water-in-oil glossy lip cosmetic formulation system of this application.

[0113] In order to compensate for the adverse effects of not using the film-forming composition provided in this application on film formation and non-stick cup performance, Comparative Examples 8 and 9 attempted to improve the film formation effect by increasing the content of the film-forming agent. However, further increasing the content of the oily film-forming agent in the water-in-oil system with high oil content exacerbated the difficulty of emulsification, resulting in oil-water separation in the materials of Comparative Examples 8 and 9. Therefore, the conventional method of increasing the content of the film-forming agent to improve film formation and non-stick cup performance is not feasible in the formulation system of this application.

[0114] II. Human Efficacy Testing Human efficacy testing was conducted on the lip cosmetics prepared in Examples 1-5 and Comparative Examples 4-8, including gloss, non-transfer effect, and moisturizing effect. Comparative Examples 1-3 and 9-10 exhibited significant water-oil separation during preparation, making it impossible to obtain a uniform and stable cosmetic material; therefore, they were unsuitable as test samples and were not subject to human efficacy testing. A total of 50 subjects participated in the testing, divided into 10 groups of 5 subjects each. The 10 groups of subjects used 10 batches of lip cosmetics prepared in Examples 1-5 and Comparative Examples 4-8, respectively. The lip gloss, non-transfer transfer rate, and lip skin moisture content change rate in the test results disclosed in this application are the average values ​​of the test results of 5 subjects in the same group using the same batch of lip cosmetics.

[0115] 1. Glossiness test after makeup application After cleansing their lips, subjects used a VISIA 7 (Canfield, USA) & ipp skin analyzer to test the glossiness of their lips. The software accompanying the analyzer was used to obtain the lip gloss value before makeup application. Then, subjects applied lip makeup products to their lips, and the VISIA 7 (Canfield, USA) & ipp skin analyzer was used again to test lip gloss. The software accompanying the analyzer was used to obtain the lip gloss value after makeup application. The rate of change in lip gloss before and after makeup application was calculated. Lip gloss change rate (%) = [(lip gloss value after makeup application - lip gloss value before makeup application) / lip gloss value before makeup application] × 100%.

[0116] 2. Non-stick cup effect test 2.1 Instant Non-Staining Test: The non-staining effect of the product was tested using image analysis. A skin analyzer, VISIA 7 (Canfield, USA) & ipp, was used to test the transfer rate of lip cosmetics on the subjects' lips. Subjects applied the lip cosmetic product to clean lips, and the color difference ΔE (T1-T0) between the lips immediately after application and the lips before application was calculated. Then, the lips were gently touched to a mirror surface for 2.0 seconds, and the color difference ΔE (T2-T1) between the lips at this time and the lips immediately after application was calculated. The instant transfer rate (%) was calculated as: [ΔE(T2-T1) / ΔE(T1-T0)] × 100%. (Where ΔE: color difference value; T0: baseline skin parameters before product application in the test area; T1: skin parameters after product application in the test area; T2: skin parameters after the transfer test in the test area). The testing and judgment rules are as follows: the lower the transfer rate of the test sample, the better the non-stick effect. If the transfer rate does not exceed 20%, the product can be considered to have a non-stick effect.

[0117] 2.2 Non-stickiness test (test method same as 2.1): Subjects applied lip makeup product to clean lips, and the color difference ΔE'(T1'-T0') between the lips immediately after applying the lip makeup product and the lips before application was calculated. After living normally for 2 hours without special treatment of the lips, drinking water or eating, the lips were gently touched to the surface of a mirror for 2.0 seconds, and the color difference ΔE'(T2'-T1') between the lips at this time and the lips immediately after applying the lip makeup product was calculated. The transfer rate (%) after 2 hours was calculated as [ΔE'(T2'-T1') / ΔE'(T1'-T0')]×100%.

[0118] Figure 1 The images show the lip comparisons of some subjects after using the lip cosmetics of Examples 1, 2, and 3, respectively, and the immediate transfer test. It can be seen that the lips have a full and high gloss immediately after makeup application, and the gloss of the lips is not significantly affected after the transfer test. Figure 2The images show the cosmetic residue left on the mirror surface after some subjects used the lip cosmetics of Example 1 and Comparative Example 6, respectively. It can be seen that in the cup transfer test of Example 1, very little lip makeup was left on the mirror surface, while in the cup transfer test of Comparative Example 6, more lip makeup was left on the mirror surface.

[0119] 3. Moisturizing effect test After cleansing their lips, subjects used a Corneometer to measure the moisture content of their lip skin, recording it as the baseline skin moisture content. Then, subjects applied lip makeup products to their lips, and the moisture content of their lip skin was measured immediately after application and again 4 hours later using a Corneometer, recording the skin moisture content T0 and T4h values. The rate of change in skin moisture content immediately after makeup application and the rate of change in skin moisture content 4 hours after makeup application were calculated. Immediate skin moisture content change rate (%) = [(Skin moisture content T0 value - Baseline skin moisture content) / Baseline skin moisture content] × 100%. 4-hour skin moisture content change rate (%) = [(Skin moisture content T4h value - Baseline skin moisture content) / Baseline skin moisture content] × 100%.

[0120] The results of the above human efficacy tests are shown in Table 17 below: Table 17 Results of Human Efficacy Testing

[0121] Examples 1-5 used an emulsified composition of isodecanyl valerate and lauryl PEG-10 tris(trimethoxy)silyl ethyl polydimethylsiloxane in a mass ratio of (4-6):1, and a film-forming composition of VP / hexadecene copolymer with a viscosity of 37500 cP-47500 cP and acrylate copolymer with a viscosity of 300 cP-360 cP in a mass ratio of (3.5-4.5):1, combined with more than 25% of trimethylpentaphenyltrisiloxane and trimethylsiloxane, which have excellent colorant isolating effects, to prepare a water-in-oil glossy lip cosmetic. After using the product, the subjects experienced a significant increase in lip gloss, with an immediate increase of 120%-140%. In the non-transferability test, the immediate transfer rate and the transfer rate 2 hours after application were both significantly lower than 20%, indicating that the product has excellent film-forming properties and a significant and long-lasting non-transfer effect. In addition, the rate of change in moisture content of the lip skin of the subjects was significantly higher than that of the control at both the immediate and 4-hour tests, and the rate of change in moisture content after 4 hours was still about 15%. It can be concluded that the products of Examples 1 to 5 all have a 4-hour moisturizing effect.

[0122] Comparative Example 4 used VP / hexadecene copolymer with a viscosity of 37500 cP~47500 cP alone; Comparative Example 5 used acrylic (ester) copolymer with a viscosity of 300~360 cP alone; Comparative Example 6 replaced VP / hexadecene copolymer and acrylic (ester) copolymer with two other commonly used film-forming agents in cosmetics, trimethylsiloxysilicate and ethylene / propylene / styrene copolymer; Comparative Example 7 used VP / hexadecene copolymer and acrylic (ester) copolymer with different viscosity characteristics; Comparative Example 10, while keeping the total mass of phenyl silicone oil unchanged, reduced the content of trimethylpentaphenyltrisiloxane and trimethylsiloxyphenyl polydimethylsiloxane, and increased the content of diphenyl polydimethylsiloxane and phenyl polytrimethylsiloxane. The film-forming properties of Comparative Examples 4-7 and 10 all decreased, manifested as an increase in immediate transfer rate or 2-hour transfer rate. The non-stick performance (especially its durability) was significantly worse than in Examples 1-5, and the film-forming effect could not be improved by increasing the content of the film-forming agent (as verified in Comparative Examples 8-9, further increasing the content of the oily film-forming agent led to the destruction of the water-in-oil emulsion structure and instability of the material). This indicates that the film-forming composition composed of VP / hexadecene copolymer with a viscosity of 37500 cP to 47500 cP and acrylic (ester) copolymer with a viscosity of 300 to 360 cP, in a mass ratio of (3.5 to 4.5): 1, combined with sufficient amounts of phenyl silicone oil trimethylpentaphenyltrisiloxane and trimethylsiloxane-oxyphenyl polydimethylsiloxane, which have excellent isolating colorant effects, achieved unexpected film-forming properties and non-stick effects.

[0123] 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.
