Description

Technical Field

[0001] The invention relates to the technical field of cosmetics, and in particular to a brightening eye shadow and a preparation method thereof. Background Art

[0002] Eye shadow is a cosmetic that shapes the eye contour and enhances the eyes. In daily life, in order to modify the eye shape and show the three-dimensional beauty of the face, it is inevitable to apply various eye shadows on the eye skin. Eye shadow mainly includes three categories: eye shadow powder, eye shadow cream and eye shadow liquid. Among them, eye shadow powder has the highest popularity due to its convenience.

[0003] In the prior art, eye shadow powder is generally made by evenly pouring eye shadow powder into an eye shadow tray mold, and using a powder pressing machine to compact the eye shadow powder to form an eye shadow powder. Eye shadow powder has the advantages of fine powder quality, easy powder collection, and easy ductility. However, the eye shadow powder obtained by the pressing and molding production process has a low overall hardness. Once it is impacted by external force, it is easy to cause the eye shadow powder to break, especially the brightening eye shadow with a large amount of pearl powder added is more likely to loosen and break.

[0004] In order to reduce the powder breakage caused by external impact of brightening eye shadow, the overall hardness of eye shadow is generally further improved by adding adhesives to eye shadow powder. Existing adhesives are generally surfactants, such as stearate / stearic acid system and sorbitan sesquioleate. Surfactants can not only make the powder and pigment evenly mixed, but also can be fully mixed with various raw materials, which is extremely convenient to use. However, existing studies have shown that surfactants have an irritating effect on the skin and can cause damage to the skin. Long-term use and penetration into the human body can also cause endocrine disorders in the human body. In view of the above situation, natural extracts are now increasingly favored as adhesives for cosmetics on the market. Summary of the invention

[0005] In order to reduce the burden on the eye skin when using eye shadow, the present application provides a brightening eye shadow and a preparation method thereof. After studying the eye shadow, the present application found that adding camellia seed oil, peony seed oil, comfrey root extract, and rice bran wax adhesive to the eye shadow formula can improve the drop resistance of the eye shadow while ensuring that the eye shadow has good ductility and adhesion, thereby reducing the problem of eye shadow flying powder.

[0006] In the first aspect, the present application provides a brightening eye shadow using the following technical solution:

[0007] Skin feel regulator: 1% to 3%;

[0008] Pearlescent agent: 30% to 40%;

[0009] Emollient: 15% to 25%;

[0010] Preservatives: 0.1% to 0.5%;

[0011] Rice bran wax adhesive: 2% to 5%;

[0012] Camellia oil: 0.5%~1.0%;

[0013] Peony seed oil: 0.3%-0.6%;

[0014] Lithospermum officinale root extract: 0.3% to 0.8%;

[0015] The balance is filler;

[0016] The filler is compounded by modified rice starch and mica in a mass ratio of (2-3):(3-4).

[0017] In the above technical solution, rice bran wax is used as the adhesive for brightening eye shadow, which can improve the hardness of eye shadow powder on the basis of avoiding the stimulation of surfactant to the skin. The new eye shadow is more resistant to falling and the safety of brightening eye shadow is improved. At the same time, rice bran wax has an activating effect on glutathione reductase and promotes the production of cholesterol and ceramide. The use of rice bran wax adhesive can also help improve the softness of the skin.

[0018] The compounding of the rice bran wax adhesive, camellia seed oil, peony seed oil and lithospermum root extract in the above-mentioned mass percentages can significantly improve the problem that the eye shadow is too hard and inconvenient to remove powder when only the rice bran wax adhesive is added, and the pearlescent agent and filler in the eye shadow can be bonded together just right without being loose or tight, so that the brightening eye shadow has a certain degree of drop resistance and appropriate hardness, and it is easier to remove powder. At the same time, it also improves the adhesion of the brightening eye shadow to the eye skin, improves the moisturizing degree of the brightening eye shadow, and significantly reduces the flying powder of the brightening eye shadow, thereby improving the user experience of the brightening eye shadow in many aspects.

[0019] In the above technical scheme, camellia seed oil contains fatty acids, triglycerides, trace elements, minerals, etc. necessary for the skin, and has the effect of promoting skin metabolism and restoring skin elasticity. It can also promote blood circulation and achieve the purpose of reducing swelling; peony seed oil is rich in vitamins, niacin, carotene, unsaturated fats, etc., and has a good nutritional effect on the skin, which can greatly improve the function of the skin epidermal cell circulatory system, promote the blood circulation of the skin capillaries, and has certain reducing swelling and anti-aging effects; lithospermum root extract has a promoting effect on tissue protease activity, has the effect of enhancing the metabolism of skin cells, and has an anti-aging effect; the combination of these three substances can promote the blood circulation ability of the skin around the eyes, achieve the purpose of eliminating edema of the eyes, and reduce the burden of applying eye shadow on the skin around the eyes.

[0020] In the above technical scheme, the rice starch and mica are compounded according to the above ratio, and the rice starch and mica particles are evenly bonded together, which improves the overall permeability of the brightening eye shadow and avoids the clogging of the pores of the eye skin when the eye shadow is applied on the eye skin. The rice starch can also absorb excess oil secreted by the eye skin, promote the fusion of the brightening eye shadow and the eye skin, further improve the lasting effect of the brightening eye shadow, and make the brightening eye shadow have a refreshing feeling when used.

[0021] Preferably, the skin feel regulator is a compound of HDI / trimethylol hexyl lactone cross-linked polymer and methyl methacrylate cross-linked polymer in a mass ratio of 1:1 to 2.

[0022] In the above technical solution, the skin feel regulator prepared according to the above ratio has the effect of better moisturizing the eye skin, preventing the floating powder phenomenon after eye makeup, and making the eye makeup effect more lasting.

[0023] Preferably, the emollient is a compound of phenyl trimethicone: caprylic / capric triglyceride: diisostearyl malate in a mass ratio of 20: (10-15): (5-9).

[0024] In the above technical solution, the emollient compounded according to the above ratio makes the texture of the brightening eye shadow more refreshing, further reducing the burden on the skin caused by applying the eye shadow to the eyes.

[0025] Preferably, the pearlescent agent is a combination of one or more of synthetic fluorphlogopite, titanium dioxide, iron oxides, tin oxide, and sodium calcium borosilicate.

[0026] In the above technical solution, the pearlescent agent compounded by the above ingredients can better and evenly bond with other ingredients in the brightening eye shadow. When the brightening eye shadow is applied on the eyelid, it can further improve the fit of the eye shadow and reduce the falling of the pearlescent agent.

[0027] Preferably, the mass ratio of the synthetic fluorphlogopite, titanium dioxide, iron oxides, and sodium calcium borosilicate is 11:12:3:9.

[0028] In the above technical solution, the pearlescent agent configured according to the above ratio has a more colorful and bright luster effect, and can have different lusters when viewed from different angles. The luster is delicate and further enhances the eyes.

[0029] Preferably, the method for preparing rice starch comprises the following steps:

[0030] 1) passing the dried prefabricated rice starch through a 40-80 mesh sieve, adding water to prepare a 30%-50% suspension, and adjusting the pH value to 8.0-8.5 with a 3% NaOH solution to obtain a prefabricated starch suspension;

[0031] 2) the starch suspension is stirred at a constant temperature of 180-220 r / min at 30-35° C., and 3% (w / w, based on dry rice starch) sodium alginate is added dropwise, and the addition is completed within 2 hours to obtain a modified starch suspension;

[0032] 3) adjusting the pH value of the modified starch solution to 5-6.5 with 3% HCl solution, drying in an oven at 40-45° C., grinding and passing through a 180-200 mesh sieve to obtain rice starch.

[0033] In the above technical scheme, the 30% to 50% suspension refers to the mass ratio of dry prefabricated rice starch and water being (3 to 5): 10, the 3% NaOH solution is prepared according to the mass ratio of NaOH and water, and the 3% HCl solution is prepared according to the volume ratio of concentrated hydrochloric acid and water. The rice starch prepared according to the above steps has better ductility than ordinary rice starch, and also has a certain hydrophobicity, which avoids the brightening eye shadow from absorbing moisture from the air during long-term placement, increases the service life of the brightening eye shadow, and reduces the amount of preservatives added in the brightening eye shadow. When the brightening eye shadow is applied to the eyelids, the brightening eye shadow will not fall off due to the discharge of skin moisture. At the same time, the discharge of skin oil can be absorbed by the rice starch, so that the brightening eye shadow and the eye skin are better integrated together, further improving the durability of the eye shadow when applied to the eyelids.

[0034] Preferably, the method for preparing rice starch further comprises placing the rice starch obtained in step 3) in a drying oven at 160-180° C. for dry heat treatment for 20-60 min, and cooling at room temperature to obtain modified rice starch.

[0035] In the above technical solution, the hydrophobic effect and oil absorption effect of the modified rice starch after drying are further improved. The refreshing experience during use is further improved without destroying the powder quality, and the ductility of the brightening eye shadow is further improved.

[0036] In a second aspect, the present application provides a method for preparing a brightening eye shadow, which adopts the following technical solution:

[0037] A method for preparing a brightening eye shadow comprises the following steps:

[0038] Step 1: Mix camellia seed oil, peony seed oil, lithospermum root extract and emollient at 70-85° C., and let stand at 70-85° C. for 0.3-0.5 h to obtain a phase A preform;

[0039] Step 2: Grind the filler, skin feel regulator, and rice bran wax binder for 1 to 1.5 hours to obtain a phase B preform;

[0040] Step 3: Mix the preform of phase A and the preform of phase B, and disperse them evenly at 80-85° C. to obtain the preform of phase C;

[0041] Step 4: Heat the phase C preform to 70-90°C, add pearlescent agent, and evenly disperse to obtain eye shadow powder;

[0042] Step 5: Pour the eye shadow powder evenly into the aluminum pan mold, press and demould to get the brightening eye shadow.

[0043] In the above technical scheme, the brightening eye shadow prepared according to the above steps can retain the original gloss of the pearlescent agent to the maximum extent, avoiding the destruction of the original gloss of the pearlescent agent in too many preparation steps. At the same time, the pearlescent agent can be more evenly distributed in the brightening eye shadow, making the prepared brightening eye shadow have a delicate and attractive gloss.

[0044] Preferably, the phase A preform in step 3 is added in 2 to 3 times, and is crushed at 2000 to 2800 r / min for 30 to 60 seconds after each addition.

[0045] In the above technical solution, the phase B preform is added in 2 to 3 times, which can further evenly disperse the components, and the rice bran wax adhesive can contact with other components to the maximum extent. The prepared brightening eye shadow has a higher hardness and is more resistant to falling.

[0046] Preferably, in step 4, the pearlescent agent is added in 2 to 3 times, and homogenized at 2000 to 3000 r / min for 10 to 20 seconds after each addition.

[0047] In the above technical solution, the pearlescent agent is added into the C phase preform in 3 to 5 times, and the pearlescent agent is more evenly dispersed in the eye shadow powder, which further reduces the falling of the pearlescent agent when the brightening eye shadow is applied to the skin, and the gloss of the prepared brightening eye shadow is more delicate and charming.

[0048] In summary, the present application includes at least one of the following beneficial technical effects:

[0049] 1. The compounding of camellia seed oil, peony seed oil, comfrey root extract and rice bran wax adhesive ensures that the various raw materials can be evenly dispersed in the brightening eye shadow, further improving the adhesion of the brightening eye shadow to the skin, enhancing the anti-fall performance of the brightening eye shadow while improving the moisturizing degree of the brightening eye shadow, reducing the problem of flying powder of the brightening eye shadow, and combined with the skin care effects of camellia seed oil, peony seed oil and comfrey root extract themselves, the brightening eye shadow has a long-lasting makeup effect and eliminates eye edema, and relieves the damage caused by makeup to the eye skin.

[0050] 2. The modified rice starch and mica are compounded in a mass ratio of (2:3) to (3:4). The rice starch and mica particles are evenly bonded together, which improves the overall permeability of the brightening eye shadow and avoids clogging of the pores of the eye skin when the eye shadow is applied on the eye skin. The rice starch can also absorb excess oil secreted by the eye skin, promote the fusion of the brightening eye shadow and the eye skin, further improve the lasting effect of the brightening eye shadow, and make the brightening eye shadow have a refreshing feeling when used.

[0051] 3. Compared with ordinary rice starch, rice starch treated by a special process has better ductility and certain hydrophobicity, which prevents the brightening eye shadow from absorbing moisture from the air during long-term storage, increases the service life of the brightening eye shadow, and reduces the amount of preservatives added in the brightening eye shadow. When the brightening eye shadow is applied to the eyelids, it will not fall off due to the discharge of skin moisture. At the same time, the discharge of skin oil can be absorbed by rice starch, making the brightening eye shadow and the eye skin better integrated, further improving the durability of the eye shadow when applied to the eyelids.

[0052] 4. The pearlescent agent composed of synthetic fluorphlogopite, titanium dioxide, iron oxide and sodium calcium borosilicate in a mass ratio of 11:12:3:9 has a more colorful and bright luster effect. It has different luster when viewed from different angles. The luster is delicate and further enhances the look of the eyes. DETAILED DESCRIPTION
