Description

Technical Field

[0001] The invention belongs to the technical field of cosmetics, and particularly relates to a moisturizing and brightening lip glaze and a preparation method thereof. Background Art

[0002] Lip gloss is a cosmetic product that is usually used to provide shine and color to the lips. It combines the color saturation of lipstick with the gloss of lip gloss. Some lip glosses also have long-lasting properties, which can maintain the makeup effect for a long time without fading easily. Lip glosses with moisturizing and brightening effects contain moisturizing ingredients such as vitamin E and natural oils such as jojoba oil or sweet almond oil, which can help keep the lips hydrated and prevent dryness. Lip gloss combines the saturated color of lipstick and the bright texture of lip gloss, achieving a new advancement in makeup.

[0003] As a cosmetic, lip gloss often encounters some common technical problems during use, which will affect the product experience and effect. (1) Lip staining: Lip gloss with high color saturation may stain the lips, that is, leave a pigment on the lips that is difficult to remove. This is because in order to improve the color rendering and durability, the proportion of certain ingredients in the lip gloss will be increased accordingly, which may cause lip staining. (2) Drying: Matte or semi-matte lip glosses require a higher content of colorants to achieve rich colors, which may cause lips to dry out. In order to ensure the long-lasting makeup effect, the proportion of moisturizing ingredients will be relatively low. (3) Slow film formation: Some mirror or glossy lip glosses may have a slow film formation process, which will affect the final makeup effect, such as the appearance of mottled or gradient effects that are too obvious. (4) Tingling or discomfort: Some people may feel slight tingling or discomfort when using lip gloss. This may be due to minor wounds on the lip skin or the lip gloss contains slightly irritating ingredients, such as alcohol. Although alcohol has a bactericidal and cleansing effect, it may cause discomfort to sensitive skin. (5) Difficult to apply evenly: Some lip glosses may not be easy to apply evenly, especially mirror lip glosses, which may require certain skills to apply properly, otherwise the surface will be uneven or the film will form unevenly.

[0004] The invention patent with publication number CN109431956A discloses a matte lip glaze and its preparation process. Through the compounding effect of a mixture of undecane and tridecane, a skin feel regulator, modified mica powder, lauroyl lysine, and sunflower seed wax, the lip glaze is relatively light and thin after application, can fully fit the lips, and has a matte texture, high color, and is conducive to film formation, giving the lip glaze a non-fading and long-lasting effect. Although the product is relatively light and thin after application, the uniformity of application is not ideal, and the lip glaze color is easily unevenly distributed on the lips, and there are patches of color differences, especially in places where the lips are dry or have dead skin.

[0005] Therefore, there is an urgent need for a lip glaze with moisturizing, brightening effects and good application uniformity. Summary of the invention

[0006] The invention aims to provide a moisturizing and brightening lip glaze and a preparation method thereof.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A moisturizing and brightening lip glaze comprises the following components in percentage by mass: 10-22% of bis-diglyceryl polyacyl adipate-2, 3-15% of polyglyceryl-2 isostearate / dilinoleate copolymer, 0.5-5% of cetyl PEG / PPG-10 / 1 polydimethylsiloxane, 7-10% of modified powder, 1-2% of plant extract, 0.5-3% of sorbitan isostearate, 0.3-3% of hydroxyethyl acrylate / sodium acryloyldimethyl taurate copolymer, 0.01-5% of colorant, 0.01-0.1% of flavor, 0.01-0.5% of preservative, 0.5-3% of emulsifier, 15-50% of emollient, 3.5-13% of humectant, 0.001-0.5% of skin conditioner, and water as the balance.

[0009] Furthermore, the emollient comprises the following components in parts by mass: 8-20 parts of diisostearyl malate, 3-10 parts of diphenylsiloxyphenyl trimethicone, 2-10 parts of octyldodecanol, and 2-10 parts of isononyl isononanoate.

[0010] Furthermore, the moisturizing agent includes the following components in parts by mass: 3-10 parts of dipropylene glycol and 0.5-3 parts of 1,2-pentanediol.

[0011] The present invention adds a specific composition of emollients and humectants to the lip glaze, and the two work together to lock in moisture and moisturize the skin, so that the skin can absorb sufficient moisture and effectively lock in the moisture, thereby achieving the purpose of long-lasting moisturizing.

[0012] Further, the skin conditioning agent is sodium hyaluronate.

[0013] Furthermore, the preparation method of the modified powder is:

[0014] (1) mixing titanium dioxide, mica powder and kaolin to obtain mixed micro powder;

[0015] (2) Using a mixer to stir 10 parts by weight of the mixed micro powder, under high-speed stirring conditions, using a spray can to spray 0.2-0.5 parts by weight of dimethyl silicone oil into the mixer, mixing evenly, drying for 2 hours, and naturally cooling to obtain a modified powder.

[0016] Furthermore, the mass ratio of titanium dioxide, mica powder and kaolin is (1.2-1.5):1:(0.6-0.8).

[0017] Ingredients in emollients, such as diisostearyl malate and octyldodecanol, have high viscosity, which will make the lip glaze thicker as a whole. Although ingredients such as isononyl isononanoate can provide good spreadability, it is difficult for the lip glaze to spread naturally when it stays on the lips, making the lip glaze's application uniformity unsatisfactory. The present invention attempts to add powder to the system to improve the application uniformity of the lip glaze, but the effect is not ideal. By modifying the powder, its compatibility in the system is improved, thereby improving the application uniformity of the lip glaze.

[0018] Furthermore, the preparation method of the plant extract is:

[0019] (1) Weighing fresh jasmine petals, grinding them, adding 8 to 10 times the weight of the petals with a 60 to 70% ethanol aqueous solution, heating and refluxing for extraction for 1 to 2 hours, extracting 2 to 3 times, filtering, combining the extracts, concentrating under reduced pressure, and freeze-drying to obtain a jasmine extract;

[0020] (2) weighing fresh petals of Malva sylvestris, grinding them, and subjecting them to supercritical extraction at 55° C.-60° C. and 35-40 MPa for 100-120 min to obtain a Malva sylvestris extract;

[0021] (3) Grind the petals of corn poppy, add water 8-10 times the weight of the petals of corn poppy to obtain a mixed solution, add Lactobacillus paracasei to the mixed solution, the active concentration of Lactobacillus paracasei in the mixed solution is 107-108 CFU / mL, perform anaerobic fermentation at a temperature of 35-40°C and a fermentation time of 8-10 hours, sterilize, filter, concentrate and dry to obtain a corn poppy extract;

[0022] (4) The jasmine flower extract, the mallow extract and the corn poppy extract are mixed to obtain a plant extract.

[0023] Furthermore, in step (4), the mass ratio of jasmine extract, mallow extract and poppy extract is 1: (1.5-1.7): (0.3-0.6).

[0024] Furthermore, the mass percentage of the plant extract in the total mass of the emollient and the humectant is greater than 4%.

[0025] The present invention promotes the water-locking and moisturizing effect of moisturizers and emollients by adding plant extracts to the lip glaze, and can improve the long-lasting water-locking effect of the lip glaze. The plant extract contains natural moisturizing factors, which work synergistically with moisturizers and emollients to enhance the moisturizing ability of the skin. When the mass percentage of the plant extract in the total mass of the emollients and moisturizers is greater than 4%, the color retention of the lip glaze can be improved. Because the plant extract helps to maintain the healthy state of the lips and reduces the decolorization caused by dryness, it can effectively help the long-lasting retention of the color of the lip glaze.

[0026] Furthermore, the emulsifier is polysorbate-60, polyglyceryl-2 dipolyhydroxystearate and soybean lecithin in a mass ratio of 1:(1.2-1.5):(0.6-0.8).

[0027] After adding the modified powder to the system of the present invention, the moisturizing lip glaze will agglomerate or the paste will delaminate when used for a long time after opening. In the present invention, the storage stability of the lip glaze can be improved by adding an emulsifier in a specific ratio.

[0028] The present invention also provides a method for preparing the moisturizing and brightening lip glaze, comprising the following steps:

[0029] (1) Mixing plant extract, moisturizer, skin conditioner and water, and heating to 45-50° C. to form a first mixture; heating colorant to 70-75° C. and keeping the temperature; fully mixing preservative and flavor to form a second mixture; and mixing the remaining components to form a third mixture;

[0030] (2) Mix the heat-insulated colorant with the third mixture and homogenize them into a uniform texture. Then cool the temperature to 40-45° C., add the first mixture, and mix thoroughly until the texture is fine. Continue to add the second mixture, mix thoroughly, and cool to room temperature to obtain a moisturizing and brightening lip glaze.

[0031] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0032] 1. The present invention adds a specific composition of emollients and humectants to the lip glaze, and the two work together to lock in moisture and keep the skin moisturized.

[0033] 2. The present invention attempts to add powder to the system to improve the uniformity of lip glaze application, but the effect is not ideal. By modifying the powder, its compatibility in the system is improved, thereby improving the uniformity of lip glaze application.

[0034] 3. The present invention promotes the water-locking and moisturizing effect of moisturizers and emollients by adding plant extracts to the lip glaze. When the mass percentage of the plant extracts in the total mass of the emollients and moisturizers is greater than 4%, the color retention of the lip glaze can be improved.

[0035] 4. After adding the modified powder to the system of the present invention, the moisturizing lip glaze will agglomerate or the paste will delaminate after long-term use after opening. In the present invention, the storage stability of the lip glaze can be improved by adding an emulsifier in a specific ratio. DETAILED DESCRIPTION

[0093] Performance Testing

[0094] Test samples: Examples 1-2 and Comparative Examples 1-9 were selected as test samples.

[0095] 1. Moisturizing effect test

[0096] Test subjects: Healthy female white-collar workers aged 18-35 with mixed skin from the same region were selected and divided into 11 groups, with 10 people in each group.

[0097] Test method: 1. Test the moisture content of the lip skin of each subject in each group, recorded as A; the amount applied by each subject is: 0.2g of the test sample is applied in an area of ​​1cm×2cm. After 3 hours, the test sample on the lips of each subject is wiped off with a tissue, and the moisture content of the lip skin in the area where the test sample was applied is tested, recorded as B. The change in the moisture content of the lip skin of each subject (i.e. BA) is recorded, and the change in each group is averaged, recorded and analyzed. The average change in the moisture content of the lip skin is calculated as (BA) / A*100%.

[0098] 2. Test subjects: Healthy female white-collar workers aged 18-35 with mixed skin from the same region were selected and divided into 11 groups, with 10 people in each group.

[0099] After washing the face with water, the subjects applied the lip gloss on the lips and scored the uniformity of the lip gloss. After 2 hours, 5 scorers scored the color of the subjects' lips, and the average of the 5 scorers was taken as the color retention score of the group of samples. The scoring range is 0-10 points, and the higher the score, the better the uniformity of the application; the better the color retention, that is, the better the durability.

[0100] 3. Place the test samples in the following four environments for observation to test the stability of the lip glaze.

[0101] Normal temperature: The sample is placed at 25°C, 60% RH (relative humidity) for 30 days.

[0102] Cold resistance: -10℃ for 10 days.

[0103] Hot and cold cycle: -10℃, 25%RH; 25℃, 60%RH; 38℃, 75%RH, 24h at each temperature, 6 cycles in total.

[0104] High temperature acceleration: The test conditions are 50℃±1℃, 25%RH±5%RH for 30 days.

[0105] If the test sample has no obvious change, it is recorded as passed; if it is delaminated or thinned, it is recorded as failed.

[0106] The results are shown in Table 1.

[0107] Table 1 Performance test results

[0108]

[0109] From the above performance test results, it can be seen that the lip glazes of Examples 1-2 have good moisturizing effect, high color retention, and high stability, especially the comprehensive performance of Example 1 is the most outstanding, which is mainly due to the synergistic effect between the components.

[0110] However, the comparative examples did not adopt the necessary technical solutions, resulting in the corresponding performance tests being significantly worse than those of the embodiments. Comparative Examples 2-4 changed the emollients and moisturizers in the lip glaze, and the water-locking and moisturizing effects decreased. The amount of plant extract added in Comparative Example 1 was reduced, and the color retention of the lip glaze was poor. The preparation method of the modified powder in Comparative Examples 5-7 was changed, and the application uniformity of the lip glaze was not ideal. The emulsifier in Comparative Examples 8-9 was changed, and the storage stability of the lip glaze was poor. The above experimental results further prove the importance of the technical solution defined in the present invention for its technical effect.

[0111] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
