Description

Technical Field

[0001] The invention relates to a lip cosmetic, in particular to a lip cosmetic made of kudzu root powder as a main material and a preparation method thereof. Background Art

[0002] Existing lip cosmetics, including lip balm, lipstick, lip gloss, lip gloss, lip glaze, etc., have complex raw materials and contain a variety of substances. They may contain unhealthy ingredients such as lanolin, wax, artificial pigments, preservatives, antioxidant BHA, preservatives, etc.; the lanolin composition is complex and can easily cause allergic reactions, such as chapped and peeling lip mucosa, itchy or slightly painful lips, etc., and it can also adsorb dust, bacteria, viruses and some heavy metal ions in the air on the lip mucosa. The artificial pigments in them may be converted into mutagens under ultraviolet radiation, causing cancer; the preservatives and antioxidant BHA in them are carcinogens; and the preservatives in them can cause breast tumors. When eating food, the human body will consume these harmful substances attached to or contained in lip cosmetics into the human body, causing health problems.

[0003] Moreover, the color of lip cosmetics is usually related to the amount of heavy metals such as lead, cadmium, cobalt, manganese, chromium, and copper in the lip cosmetics. The darker the color, the higher the heavy metal content. Heavy metals can cause potential harm to the brain and nervous system, causing anemia, abdominal pain, acute renal failure, and brain neuropathy, which seriously affect human health. In addition, due to the artificial synthesis and heavy metal raw materials contained in lip cosmetics, harmful wastewater and waste gas are generated in the existing lip cosmetics production process, causing environmental pollution.

[0004] Healthy lipsticks are disclosed in the prior art, for example, the formula and preparation process of a healthy lipstick with application number CN201810954911.6 discloses that the raw materials of the healthy lipstick are: diisostearyl malate, tri(ethylhexanoin)glyceryl, bis-diglycerol polyacyl adipate-2, ozokerite, beeswax, octyldodecanol, polyglycerol-2, triisostearate, polyethylene, microcrystalline wax, macadamia ternifolia seed oil, phytosterol (vitamin E), avocado tree (BUTYROSPERMUM PARKII) oil, phytosterols, honey extract, phenoxyethanol, CI 77891, CI 45380, CI77492. Although the above-mentioned lipstick raw materials use natural and safe raw materials, all raw materials strictly adopt the national pharmaceutical standard extraction method to achieve a healthy lipstick that everyone can use and eat.

[0005] However, the ingredients used in the raw materials of the above-mentioned lipsticks, such as diisostearyl malate, triethylhexanoin, bis-diglyceryl polyacyladipate-2, and ozokerite, are all artificial synthetic ingredients, which may cause skin sensitivity or allergic reactions, and the production and decomposition process of the above-mentioned ingredients will also impose a burden on the environment; in addition, even if the above-mentioned ingredients pass the regulatory safety assessment, long-term use of lipsticks containing such synthetic ingredients may also pose certain health risks.

[0006] Therefore, existing lip cosmetics, especially colored lip cosmetics, are still unhealthy to the human body during use and unfriendly to the environment during the preparation and decomposition processes.

[0007] Moreover, even if natural raw materials are used in lip cosmetics, the prior art does not use kudzu root powder as the main raw material of lipstick, mainly because when kudzu root powder is used as the main material, it cannot be formed after being gelatinized with water alone, and the final product is soft and collapsed and cannot be used; and if kudzu root powder is directly combined with other ingredients, the amount of oil must be increased, and the finished product is not only soft and collapsed, rough and granular, but also the high oil content will cause the oil color in the pigment to separate, and it is impossible to uniformly dissolve, and it is impossible to obtain a complete molding and uniform quality product. The above problems limit the application of kudzu root powder, resulting in the difficulty of preparing lip cosmetics using kudzu root powder as the main raw material of lip cosmetics in the prior art.

[0017] In the aforementioned lip cosmetics made with kudzu root powder as the main ingredient, the salt is edible salt, and the mesh number of the edible salt is 80-100 meshes.

[0018] The preparation method of the lip cosmetics comprises the following steps: mixing edible plant juice and kudzu root powder, ripening the mixture, and then uniformly mixing the mixture with salt, oil, beeswax and edible pigment in proportion.

[0019] The aforementioned method for preparing lip cosmetics specifically comprises the following steps:

[0020] A. Mix kudzu root powder and edible plant juice evenly, heat in a water bath to 70℃~90℃, stir and ripen to obtain product A;

[0021] B. Mix the natural food coloring and product A evenly to obtain product B;

[0022] C. Add salt to product B and mix well to obtain product C;

[0023] D. Heat the oil in a water bath to 40℃~50℃, add it to product C and stir evenly, then heat it in a water bath to 40℃~50℃ and stir evenly to obtain product D.

[0024] E. Melt the solid beeswax into liquid in a water bath, add it to product D, heat it in a water bath to 40℃~50℃, stir evenly to obtain liquid lip cosmetics;

[0025] F. Put the liquid lip cosmetics into a mold, let it stand and freeze it to obtain solid lip cosmetics.

[0026] In the aforementioned method for preparing lipstick, in the step F, the freezing temperature is -10°C to -5°C, and the freezing time is 10 to 20 minutes.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention uses kudzu root powder as the main raw material of the lip cosmetics of the present invention. The kudzu root isoflavones and other substances in the kudzu root powder have multiple beneficial effects on the human body, such as lowering blood lipids, lowering blood pressure, lowering blood sugar, and promoting gastrointestinal motility. In addition, the kudzu root powder contains a large amount of mucus and starch, which can form a protective skin film to prevent the invasion of external bacteria.

[0029] The edible plant juice used as auxiliary material, vitamins, flavonoids, alkaloids and other plant active factors, carotenoids, lutein and other plant nutrients in the edible plant juice have multiple physiological promoting effects on humans and have auxiliary effects on human health;

[0030] The floral juice used in edible plant juice also has special aroma and efficacy. For example, the aroma of gardenia, rose, jasmine, mint, chrysanthemum, cassia seed, tangerine peel, etc. has the effect of calming the mind, soothing emotions, and helping sleep.

[0031] The kudzu root powder is mixed with edible plant juice with a concentration of more than 30% to obtain a viscous and moldable base material, which is conducive to the molding of lip cosmetics, and the various ingredients are highly integrated, and the finished product is delicate and smooth; the kudzu root powder also contains a unique sweet smell, which combined with the fragrant smell in the edible plant juice can increase the rich fragrance of the lip cosmetics and improve the diversity of lip cosmetics.

[0032] The invention can selectively add the amount of natural edible pigment according to the demand to prepare lip cosmetics without color or with multiple colors, and is suitable for a wide range of people.

[0033] If natural edible pigments are combined with kudzu root powder, a variety of colors can be added to lip cosmetics, and it is healthy and burden-free. Moreover, after kudzu root powder is combined with edible plant juice, it has the characteristics of a gel and has high viscosity. It can be combined with natural edible pigments to improve the coagulation stability of natural edible pigments, thereby allowing lip cosmetics to maintain pure color for a long time.

[0034] The lipstick raw material of the present invention also uses salt. The combination of salt and kudzu root powder can improve the viscosity of kudzu root powder, making it more stable when combined with other ingredients. The combination of salt with edible plant juice and natural edible pigment can enhance the freshness, color brilliance, stability and durability of lip cosmetics, thereby improving the storage life and service life of lip cosmetics. The salt used is edible salt, the main component of which is sodium chloride, which is a neutral inorganic salt and has an effective sterilization and anti-inflammatory effect on the skin.

[0035] No water is added during the preparation process of the lip cosmetics of the present invention. Since kudzu root powder belongs to starch products, the present invention utilizes the characteristics of kudzu root powder of starch, such as low gelatinization temperature, high transparency, strong viscosity and stability, to directly mix with edible plant juice, stir and mature evenly, and obtain a basic material with high viscosity and formability, which provides a raw material basis for subsequent processes, thereby facilitating the preparation of a lip cosmetic product with high formability.

[0036] The temperature of water bath aging is controlled between 70°C and 90°C, at which the kudzu root isoflavones and other substances in the kudzu root powder and the various vitamins and nutrients in the edible plant juice will not be decomposed, reduced or lost; and at this temperature, the kudzu root after aging not only achieves the effects of high transparency, bright color, texture, viscosity, strong stability, etc., but also can fully retain the sweet fragrance of the kudzu root and the color, fragrance and taste of the edible plant juice, giving full play to the role of the kudzu root as a natural thickener, stabilizer, adhesive and skin care agent, which is helpful to the molding degree of the prepared lip cosmetics, ensuring the original color and pure fragrance of the lip cosmetics, so that the finally prepared lip cosmetics are completely molded, smooth in surface, moderately soft and tough, bright and beautiful, fragrant and elegant, highly moisturizing and delicate, and rich in various ingredients beneficial to the human body.

[0037] During the process of adding the oil, the oil is heated in a water bath twice to 40°C to 50°C, so that the oil and other materials can be mixed more quickly and evenly, avoiding coagulation and the decomposition, reduction and loss of vitamins and nutrients.

[0038] Moreover, during the preparation process of the lip cosmetics of the present application, no waste water or waste gas is generated, the preparation process is environmentally friendly, and the released water is also an organic fertilizer that is beneficial to the soil.

[0039] Since the ingredients of lip cosmetics are all edible natural plant ingredients, the raw materials are easy to obtain and the cost is low; moreover, when the lip cosmetics are decomposed, they will not damage the environment and are environmentally friendly and pollution-free.
