Description

Technical Field

[0001] The present application relates to the field of color cosmetics technology, and more specifically, to an oil-in-water mirror-finished moisturizing long-lasting lip glaze and a preparation method thereof. Background Art

[0002] Lip gloss is a kind of makeup cosmetics, usually used to provide gloss and color to the lips. It combines the color saturation of lipstick and the glossiness of lip gloss, achieving a new advancement in makeup.

[0003] Currently, the lip glazes on the market can be divided into matte lip glaze, velvet lip glaze and mirror lip glaze based on the makeup feel. Among them, compared with matte lip glaze and velvet lip glaze, mirror lip glaze is more moisturizing. After applying on the lips, it will form a film naturally, presenting a mirror-like gloss effect, which can make the lips look naturally plump.

[0004] However, general mirror lip glaze is a pure oil formula system, which is sticky and not refreshing after application. Summary of the invention

[0005] In order to improve the freshness of the mirror lip glaze on the skin, the present application provides an oil-in-water mirror moisturizing long-lasting lip glaze and a preparation method thereof.

[0006] In the first aspect, the present application provides an oil-in-water mirror-finish moisturizing long-lasting lip glaze, which adopts the following technical solution: An oil-in-water mirror-finish moisturizing long-lasting lip glaze, which is an oil-in-water emulsified system; The aqueous phase includes polyacrylate cross-linked polymer-6, a hydrophilic emulsifier, a moisturizer, a pigment and a preservative; The oil phase includes emollients, lipophilic emulsifiers, color powders and thickeners: The oil-in-water mirror-finish moisturizing long-lasting lip glaze is composed of the following components calculated by weight percentage: Polyacrylate cross-linked polymer-6 0.1~1%; Hydrophilic emulsifier 1.1-10.5%; Lipophilic emulsifier 0.2-2%; Moisturizer 5-13%; Thickener 1-5%; Emollients 26-55%; Emulsifying thickener 0.5-3%; Pigment 1-3%; Color powder 0.5-5%; Preservatives 0.5-1%; Aromatherapy agent 0.05-0.1%; Water is the balance.

[0007] By adopting the above technical scheme, the oil-in-water emulsification technology is used to evenly disperse the oil phase and then wrap it in the water phase, so that the lip glaze is prepared into a stable oil-in-water emulsification system. On the one hand, when the lip glaze is applied, the first thing it contacts is the water phase, which can make the skin feel light and non-sticky. Then the water molecules in the water phase are absorbed by the skin, the moisturizer can lock the moisture of the lips, and the oil phase is evenly spread on the skin surface, gradually forming a glossy film, which can create a full and plump lip makeup effect. On the other hand, the oil phase is toned with lipophilic color powder, and the water phase is toned with hydrophilic pigments. The polyacrylate cross-linked polymer-6 in the water phase has a good thickening and suspension effect, which can not only effectively and stably disperse the pigment, but also help the pigment in the lip glaze to stay on the skin and improve the lasting effect of the lip glaze, but also reduce the particle size of the emulsion, which is conducive to the skin absorbing water molecules, and the moisturizer locks the moisture of the lips, thereby improving the moisturizing property of the lip glaze.

[0008] At the same time, the compounding of hydrophilic emulsifier and lipophilic emulsifier can expand the effective volume due to the difference in HLB value (hydrophilic-lipophilic balance), so that the two emulsifiers can be adsorbed on the interface, forming a directional arrangement to form a tight interface film, effectively preventing emulsion aggregation and improving the stability of the emulsification system. Therefore, the lip glaze prepared by it has the advantages of high stability, refreshing skin feel, long-lasting makeup effect and high moisturizing property.

[0009] Preferably, calculated by weight percentage of the oil-in-water mirror-finish moisturizing long-lasting lip glaze, the hydrophilic emulsifier is composed of a mixture of 1-10% polysorbate-60 and 0.1-0.5% inulin lauryl carbamate.

[0011] By adopting the above technical scheme, polysorbate-60 is selected as the main emulsifier, and it is matched with inulin lauryl carbamate with large steric hindrance, cetyl PEG / PPG-10 / 1 polydimethylsiloxane and sorbitan isostearate, the stability of the water-in-oil emulsion system can be improved, and the particle size of the formed water-in-oil emulsion system can be effectively reduced. It does not change after 30 days of high and low temperature cycle storage, and the skin feels refreshing, and the makeup-lasting effect and moisturizing effect are excellent.

[0012] Preferably, the oil-in-water mirror-finish moisturizing long-lasting lip glaze is composed of the following components calculated by weight percentage: Polyacrylate cross-linked polymer-6 0.1~1%; Polysorbate-60 1-10%; Cetyl PEG / PPG-10 / 1 polydimethylsiloxane 0.1-1%; Sorbitan isostearate 0.1-1%; Inulin lauryl carbamate 0.1-0.5%; Butanediol 1-3%; Glycerol 2-5%; Diglycerol 2-5%; Disteardimethylammonium hectorite 1-5%; Diphenyl polydimethylsiloxane 10-20%; Diisostearyl malate 10-20%; Bis-diglyceryl polyacyl adipate-2 5-10%; C10-30 acid cholesterol / lanosterol mixed ester 1-5%; Emulsifying thickener 0.5-3%; Pigment 1-3%; Color powder 0.5-5%; Preservatives 0.5-1%; Aromatherapy agent 0.05-0.1%; Water is the balance.

[0013] By adopting the above technical scheme, the above raw materials are mixed in a specific ratio to prepare a lip glaze with a water-in-oil emulsion system. The lip glaze has a light and non-sticky feel, a stable structure, and a small particle size. It can spread on the skin surface to form a uniform and shiny film layer, hydrate and lock in moisture for the skin, and has excellent makeup-lasting effect and hydrating and moisturizing effect.

[0014] Preferably, calculated based on the weight percentage of the oil-in-water mirror-finish moisturizing long-lasting lip glaze, the weight percentage of polyacrylate cross-linked polymer-6 is 0.17-0.25%.

[0015] By adopting the above technical solution, adding polyacrylate cross-linked polymer-6 into the lip glaze formula according to the above preferred amount can improve the pigment dispersion and effectively reduce the emulsion particle size. Therefore, the obtained lip glaze has the characteristics of refreshing skin feel, long-lasting makeup and excellent moisturizing performance.

[0016] Preferably, calculated by weight percentage of the oil-in-water mirror moisturizing long-lasting lip glaze, the weight percentage of polysorbate-60 is 4-8%, the weight percentage of cetyl PEG / PPG-10 / 1 polydimethylsiloxane is 0.3-0.7%, the weight percentage of sorbitan isostearate is 0.3-0.7%, and the weight percentage of inulin lauryl carbamate is 0.2-0.4%.

[0017] Preferably, the emulsifying thickener is composed of the following components by weight percentage: Polyacrylamide 0-10%; Sodium polyacrylate 10-20%; Isohexadecane 20-30%; Laureth-7 20-30%; Water 40-50%.

[0018] By adopting the above technical scheme, the above raw materials are added to the lip glaze formula according to the above preferred dosage, and the prepared lip glaze has the effects of high gloss, refreshing skin feel, not easy to fall off and moisturizing, and can create a full and plump lip makeup effect to meet consumer needs.

[0019] In a second aspect, the present application provides a method for preparing an oil-in-water mirror-finish moisturizing long-lasting lip glaze, using the following technical solution: A method for preparing an oil-in-water mirror-finish moisturizing long-lasting lip glaze, comprising the following steps: S1: homogenously mix polyacrylate cross-linked polymer-6 and 15-25 wt% water at 85-90° C. and 3000-4000 r / min for 5-10 min to obtain a transparent gel; S2: After the remaining water and pigment are stirred and mixed at 25-35°C and 30-40 r / min for 8-10 minutes, the transparent gel is added and stirred and mixed for 8-10 minutes to obtain a colored gel; S3: After mixing the moisturizer and the preservative, add them to the colored gel, stir and mix them at 30-40 r / min for 8-10 minutes, then add the hydrophilic emulsifier, stir and mix them for 8-10 minutes to obtain an aqueous phase; S4: mixing and dissolving the emollient and the lipophilic emulsifier at 85-90° C. to obtain a base material; 15-25 wt% of the base material is mixed with the color powder and the thickener and ground to a particle size of 10-40 μm, then added to the remaining base material, mixed and dissolved, and cooled to 25-35° C. to obtain an oil phase; S5: Add the oil phase to the water phase at a stirring speed of 40 to 50 r / min and a homogenizing speed of 3000 to 4000 r / min, and homogenize and mix for 8 to 10 minutes. Then, add the emulsifying thickener, and homogenize and mix for 4 to 5 minutes. Stop the homogenization, and then add the fragrance, and stir and mix for 8 to 10 minutes to obtain an oil-in-water mirror moisturizing long-lasting lip glaze.

[0020] By adopting the above technical scheme, polyacrylate cross-linked polymer-6 and 15-25wt% of water are first prepared into a transparent gel, and then mixed with a pigment aqueous solution and a hydrophilic emulsifier, the dispersion stability of the pigment in the water phase can be effectively improved to obtain a toned water phase. Then, 15-25wt% of the base material is first mixed with the color powder and a thickener and ground to 10-40μm, and then mixed with the remaining base material, the dispersion stability of the color powder in the oil phase can be effectively improved to obtain a toned oil phase. Therefore, the present application can stably and evenly color the water phase and the oil phase by controlling the mixing steps and amounts of the raw materials, and then add the colored oil phase to the water phase for homogeneous stirring and mixing. The oil phase can be evenly dispersed in the water phase and wrapped by the water phase, and finally an emulsifier stabilizer and isohexadecane are added to form a water-in-oil emulsion system with a stable structure and a small particle size. The lip glaze produced has a refreshing and non-sticky feel, can form a long-lasting glossy film layer on the skin surface, hydrate and shrink the skin, and create a high-gloss and full pouty lip makeup.

[0021] In summary, this application has the following beneficial effects: 1. Since polyacrylate cross-linked polymer-6 has a thickening and suspending effect, the pigment is stably dispersed in the water phase. After the water-in-oil lip glaze contacts the skin, the pigment in the water phase can be stably attached to the skin surface, which is beneficial to improving the lasting effect of the lip glaze; 2. In this application, polysorbate-60, cetyl PEG / PPG-10 / 1 polydimethylsiloxane, sorbitan isostearate and inulin lauryl carbamate are preferably used in combination, which can improve the strength of the interface film and the stability of the water-in-oil emulsion system, which is beneficial to the preparation of a lip glaze that is refreshing, not easy to fall off and moisturizing; 3. The method of the present application controls the mixing amount and steps of the raw materials so that the oil phase of the color powder can be evenly dispersed in the water phase of the pigment to form oil droplets with stable structure and small particle size. Therefore, the obtained lip glaze has the effects of watery mirror, refreshing skin feel, moisturizing and not easy to come off, which can meet the consumer's demand for high-quality lip glaze products.

[0025] Example 1 A water-in-oil mirror-finish moisturizing long-lasting lip glaze, the components and their corresponding weights (kg) are shown in the following table.

[0026] The preparation method of the above-mentioned oil-in-water mirror-finish moisturizing long-lasting lip glaze comprises the following steps: S1: Polyacrylate cross-linked polymer-6 and 15 wt% water were homogenously mixed at 85°C and 3000 r / min for 5 min to obtain a transparent gel; S2: After the remaining water and pigment are stirred and mixed at 25°C and 30 r / min for 8 minutes, the transparent gel is added and stirred and mixed for 8 minutes to obtain a colored gel; S3: After mixing butylene glycol, glycerin, diglycerin and preservatives, add them to the colored gel, stir and mix at 30 r / min for 8 minutes, then add polysorbate-60 and inulin lauryl carbamate, stir and mix for 8 minutes to obtain an aqueous phase; S4: diphenyl dimethicone, diisostearyl malate, cetyl PEG / PPG-10 / 1 dimethicone, sorbitan isostearate, bis-diglyceryl polyacyl adipate-2 and C10-30 acid cholesterol / lanosterol mixed ester are mixed and dissolved at 85° C. to obtain a base material; 15 wt % of the base material is mixed with the color powder and disteardimethylammonium hectorite and ground to a particle size of 10 μm, then added to the remaining base material, mixed and dissolved, and cooled to 25° C. to obtain an oil phase; S5: Add the oil phase to the water phase at a stirring speed of 45 r / min and a homogenizing speed of 3000 r / min. After homogenizing and mixing for 8 minutes, add the emulsifying thickener first, and homogenize and mix for 4 minutes. Stop the homogenization, and then add the fragrance. Stir and mix for 8 minutes to obtain an oil-in-water mirror moisturizing long-lasting lip glaze.

[0027] In the embodiment of the present application, the emulsifying thickener is composed of a mixture of 10% polyacrylamide, 10% sodium polyacrylate, 20% isohexadecane, 20% laureth-7 and 40% water.

[0028] Embodiment 2-3 A water-in-oil mirror-finish moisturizing long-lasting lip glaze, which is different from Example 1 in that the components and their corresponding weights (kg) are shown in the following table.

[0029] The oil-in-water mirror moisturizing long-lasting lip glazes prepared in Examples 1 to 3 were tested for efficacy evaluation of brightness, skin feel, long-lasting properties, and moisturizing properties. The test results are shown in the following table.

[0030] By analyzing the data in the above table, it can be seen that the water-in-oil mirror moisturizing long-lasting makeup lip glaze prepared in Examples 1 to 3 has a brightness of up to 7.8 to 8.1 points, a skin feel of up to 8.1 to 8.8 points, a long-lasting makeup of up to 8.6 to 8.9 points, and a moisturizing property of up to 7.8 to 8.5 points. The reason for this may be that the increase in the content of polyacrylate cross-linked polymer-6 can effectively improve the dispersion stability of the pigment and reduce the particle size of the emulsion, thereby improving the comprehensive efficacy of the lip glaze. However, it can be seen from Examples 2 and 3 that the efficacy of 0.25% polyacrylate cross-linked polymer-6 and 0.23% polyacrylate cross-linked polymer-6 is similar. This shows that in the total raw materials for the preparation of the water-in-oil mirror moisturizing long-lasting makeup lip glaze of the present application, when the weight percentage of polyacrylate cross-linked polymer-6 is 0.17 to 0.25%, the prepared lip glaze can form a water-light mirror film layer on the lips, and the skin feels refreshing, is not easy to remove makeup, and has high moisturizing properties.

[0031] Embodiments 4 to 7 A water-in-oil mirror-finish moisturizing long-lasting lip glaze is different from Example 1 in that the hydrophilic emulsifier, the lipophilic emulsifier and water and their corresponding weights (kg) are shown in the following table.

[0034] Compared with Examples 6 and 7, the skin feel scores, makeup lasting scores and moisturizing scores of Examples 1, 4 and 5 are all significantly increased. The reason for this may be that the use of polysorbate-60 as the main emulsifier, combined with inulin lauryl carbamate with large steric hindrance, the resulting water-in-oil emulsion system has high stability and small oil droplet size, thereby improving the comprehensive efficacy of the lip glaze. This shows that in the total raw materials for preparing the water-in-oil mirror moisturizing long-lasting makeup lip glaze of this application, when the hydrophilic emulsifier is composed of a mixture of polysorbate-60 and inulin lauryl carbamate, and the lipophilic emulsifier is composed of a mixture of cetyl PEG / PPG-10 / 1 polydimethylsiloxane and sorbitan isostearate, the freshness, makeup lasting effect and moisturizing effect of the lip glaze can be improved.
