Description

Technical Field

[0001] The present application relates to the technical field of cosmetics, and in particular to a cellulite firming cream and a preparation method thereof. Background Art

[0002] At present, the skin care products on the market are mainly divided into two basic types: water-in-oil and oil-in-water. Water-in-oil skin care products have better spreadability, do not feel greasy when used, and have a refreshing feeling, but their shortcomings are also obvious: first, the moisturizing effect is not as good as that of oil-in-water; secondly, because the water phase is in the external phase, it is easier to play, and the moisturizing effect is not sustained enough; in addition, if there are too many active ingredients and the ionicity is too strong, the water-in-oil product is either difficult to thicken, or even if it is thickened, it will be too thick because too many thickening ingredients are added, and the skin feel is very poor and easy to rub mud. Oil-in-water skin care products have a smooth appearance and excellent lubrication. Because its water phase is in the internal phase, the water is slowly released. Therefore, except for the difference in emulsifiers, the moisturizing property of oil-in-water products is significantly stronger than that of water-in-oil products when other ingredients are the same. Furthermore, the ionicity brought by the addition of highly active ingredients has less effect on oil-in-water, and it is easier to add higher content of active ingredients to oil-in-water, which can better make functional products and get better skin feel. Therefore, the oil-in-water system is more suitable for making highly moisturizing and highly effective products.

[0003] In the prior art, in order to prevent skin sagging, loss of elasticity, wrinkles, etc. and keep the skin young, people have proposed anti-aging products mixed with various ingredients such as hydrolyzed collagen, hyaluronic acid, peptides, retinol and its derivatives. However, if these ingredients are used in large quantities, many problems will arise in terms of the actual anti-aging effect, skin feel and safety. For example, the molecular weight of hydrolyzed collagen is too large and it is not easy to penetrate the human skin barrier to reach the dermis; hyaluronic acid cannot essentially slow down the loss of collagen; peptides and retinol have certain irritation and safety risks to the skin, etc.

[0004] Currently, most skin tightening products on the market rely on chemical synthetic ingredients. Although they have certain firming effects, long-term use may bring side effects, such as irritation and potential health risks. Natural plant extracts are gradually gaining attention due to their low toxicity and good biocompatibility, but there are still challenges in improving their stability and permeability. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present application provides a cellulite firming cream and a preparation method thereof. The cellulite firming cream prepared in the present application is mild and non-irritating, has high stability, and has good moisturizing effect. It also has firming and anti-wrinkle effects, and can effectively improve skin elasticity, thereby making the skin firmer.

[0006] In a first aspect, the present application provides a cellulite firming cream, which adopts the following technical solution: A cellulite firming cream, comprising a water phase, an oil phase and an additive phase, wherein the water phase, by weight, comprises the following preparation materials: Carbomer 980 0.4-0.5 parts, chlorphenesin 0.09-0.11 parts, preservative A 0.09-0.11 parts, deionized water 70-72 parts; the oil phase, by weight, includes the following raw materials: stearic acid 4.8-5.3 parts, monoglyceride 2.8-3.1 parts, emulsifier 5.3-5.7 parts, 1618 alcohol 5.8-6.3 parts, 26# white oil 7.7-8.2 parts; the additive phase, by weight, includes the following raw materials: anti-allergic agent 0.03-0.04 parts, moisturizing anti-aging agent 0.03-0.04 parts, sodium hydroxide aqueous solution with a mass concentration of 20% 0.4-0.6 parts, thermal sensitizer 0.14-0.16 parts, preservative B 0.5-0.6 parts, flavor 0.2-0.3 parts.

[0007] By adopting the above technical scheme, the thermal agent such as vanillyl butyl ether, as a thermal agent derived from natural plants, mainly promotes blood circulation, accelerates microcirculation and stimulates subcutaneous fat metabolism. Vanillyl butyl ether is an oil-soluble thermal agent that can produce a mild and lasting pyrogenic effect. It stimulates the microcirculation of small blood vessels under the skin and promotes capillary blood circulation, thereby helping the skin to restore health and vitality. Carbomer 980 is a polyacrylic acid cross-linked polymer with high viscosity, high transparency and short rheology. It can form a high-viscosity gel at a very low concentration. Its main functions include thickening, suspension, emulsification and skin protection. Chlorphenesin has good moisturizing properties and can effectively moisturize the skin and maintain the moisture balance of the skin. This is very important for firming creams because moisturizing is the key to maintaining skin elasticity and firmness. Its main functions include moisturizing, antifungal and enhancing product stability. Monoglyceride, also known as dihydroxypropyl octadecanoate, is a chemical substance prepared by esterification of C16-C18 long-chain fatty acids with glycerol and is often used as an emulsifier. As an oily substance, 26# white oil can form an oil film on the skin, thereby blocking the evaporation of skin moisture and enhancing the moisturizing effect of the moisturizer. 1618 alcohol can reduce the interfacial tension between the oil phase and the water phase, allowing the two originally immiscible substances to blend better together. In the firming cream, it helps to form a stable emulsified system to prevent the product from being unstable, such as stratification and precipitation. The role of stearic acid in the firming cream mainly includes moisturizing, emulsification, lubrication and anti-aging. Anti-allergic agents (such as dipotassium glycyrrhizinate and Runfuyi) work together to reduce skin inflammation and allergic reactions. Dipotassium glycyrrhizinate is anti-inflammatory and anti-allergic by inhibiting the increase of white blood cells and preventing the release of histamine, while Runfuyi (the main ingredient is oat kernel extract) helps protect the skin from free radical damage with its antioxidant, moisturizing and soothing properties, maintain the skin's moisturizing system, and reduce skin discomfort. Moisturizing and anti-aging agents (such as Runfugan and Moist PM-II): The main ingredient of Moist PM-II is glyceryl glucoside, which has the effect of deep hydration and long-lasting moisturizing, and is suitable for use in dry environments. Moist PM-II also provides excellent moisturizing and anti-aging properties. The combination of the two enhances the moisturizing and anti-aging capabilities of the product, ensuring that the skin remains hydrated and firmed after use. In summary, these components, through their respective effects and their synergistic effects, jointly enhance the moisturizing, firming and anti-wrinkle effects of the cellulite firming cream, while ensuring the mildness and stability of the product.

[0008] Preferably, the anti-allergic agent is prepared by mixing Run Fu Yi and dipotassium glycyrrhizinate in a mass ratio of 1:2.

[0009] By adopting the above technical solution, dipotassium glycyrrhizinate: This is an effective anti-inflammatory and anti-allergic ingredient that reduces skin inflammation and allergic reactions by inhibiting the increase of leukocytes and preventing the release of histamine. This allows the product to reduce irritation to the skin during use and is particularly suitable for sensitive skin. Runfuyi: The main ingredient is oat kernel extract, which has a variety of skin care benefits. It not only has antioxidant properties, which can help protect the skin from damage by free radicals, but also has excellent moisturizing and soothing properties, which helps to maintain the skin's hydration and reduce skin discomfort. When these two ingredients are mixed in a mass ratio of 1:2, they can play the following roles and synergistic effects in the cellulite firming cream: The combination of dipotassium glycyrrhizinate and Runfuyi can more effectively reduce skin inflammation and allergic reactions and improve the overall anti-allergic performance of the product. The moisturizing properties of Runfuyi combined with the anti-inflammatory effects of dipotassium glycyrrhizinate can keep the skin moisturized while anti-allergic, and prevent skin dryness caused by anti-allergic. The soothing properties of Runfuyi and the anti-inflammatory effects of dipotassium glycyrrhizinate work together to comprehensively relieve skin discomfort and make the skin more comfortable and healthy after use. In summary, the mixture of Runfuyi and dipotassium glycyrrhizinate in a mass ratio of 1:2 in the cellulite firming cream can not only effectively reduce skin inflammation and allergic reactions, but also provide good moisturizing and soothing effects, thereby comprehensively improving the skin care performance of the product.

[0010] Preferably, the emulsifier is prepared by mixing glyceryl stearate and PEG-100 stearate in a mass ratio of 1:1.

[0011] By adopting the above technical scheme, glyceryl stearate has good emulsifying properties and can effectively mix the oil phase and the water phase to form a stable emulsion. In addition, it can increase the viscosity of the product and improve the skin feel. It is generally considered to be a mild emulsifier with low skin irritation. PEG-100 stearate is an efficient O / W (oil-in-water) emulsifier that can disperse oil more evenly in water and improve the stability of the emulsion. It also has good permeability and hydrophilicity, which helps the active ingredients to penetrate into the skin better. It is also considered to be a mild emulsifier for the skin with low irritation. When glyceryl stearate and PEG-100 stearate are mixed in a mass ratio of 1:1, they can play a synergistic effect in the following aspects: the mixed use of the two emulsifiers can significantly improve the emulsification efficiency, make the mixing of the oil phase and the water phase more stable, and prevent the occurrence of stratification. The thickening effect of glyceryl stearate combined with the hydrophilicity of PEG-100 stearate can make the product form a thin and easily absorbed protective film on the skin, improving the comfort during use. Mixed emulsifiers can enhance the overall stability of the product, extend the shelf life of the product, and ensure that there will be no deterioration during storage and use. The efficient penetration performance of PEG-100 stearate combined with the mildness of glyceryl stearate can help active ingredients such as anti-allergic agents, moisturizing and anti-aging agents to better penetrate into the deep layers of the skin and exert their effects. In summary, the use of glyceryl stearate and PEG-100 stearate in a 1:1 mass ratio can not only significantly improve the emulsification effect and product stability, but also improve skin feel and promote the penetration of active ingredients. It is an important component of the cellulite firming cream formula.

[0012] Preferably, the moisturizing and anti-aging agent is composed of Runfugan and Moist PM-II was mixed in a mass ratio of 1:2.

[0013] By adopting the above technical solution, Runfugan: The main ingredient is glyceryl glucoside, which has the effect of deep hydration and long-lasting moisturizing, and is particularly suitable for use in dry environments. It can penetrate into the bottom layer of the skin, replenish moisture, form a moisturizing barrier, prevent moisture loss, and keep the skin hydrated for a long time. Moist PM-II is a highly effective moisturizing and anti-aging ingredient that provides excellent moisturizing effects while also having anti-aging properties. It forms a protective film on the skin's surface, locking in moisture, reducing the appearance of fine lines and wrinkles, and improving skin's elasticity and firmness. When MoistPM-II is mixed in a mass ratio of 1:2, their synergistic effect can significantly enhance the moisturizing and anti-aging effects of the product: the deep hydration ability of Runfugan is Combined with the long-lasting moisturizing effect of Moist PM-II, it can fully moisturize the skin from the inside out, keeping the skin hydrated for a long time. The anti-aging properties of Moist PM-II and the moisturizing effect of Runfugan promote each other, not only reducing the appearance of fine lines and wrinkles, but also improving the overall elasticity and firmness of the skin. The two ingredients work together to form an effective protective film on the skin surface, locking in moisture while resisting external environmental damage to the skin and maintaining the skin's health. In summary, Runfugan and Runfugan in moisturizing anti-aging agents are Moist PM-II is scientifically formulated to work in an excellent synergistic way, providing comprehensive moisturizing and anti-aging care for the skin, keeping it hydrated, firm and youthful.

[0014] Preferably, the preservative A is imidazolidinyl urea.

[0015] Preferably, the preservative B is phenoxyethanol.

[0016] Preferably, the thermal sensitizer is vanillyl butyl ether.

[0017] Preferably, the essence is one of eucalyptus essential oil, rose essential oil and vanilla essential oil.

[0018] In a second aspect, the present application provides a method for preparing a cellulite firming cream, using the following technical solution: As a general technical concept, the present application also provides a method for preparing the above-mentioned cellulite firming cream, comprising the following steps: S91. Add 1 / 3 of deionized water into the reactor according to the mass fraction, turn on the homogenizer and slowly add Carbomer 980 into the deionized water. After the dispersion is complete, turn off the homogenizer, add the remaining deionized water, chlorphenesin and preservative A, start heating and stirring to obtain an aqueous phase; S92, when the water phase is heated to 50-55° C., add the oil phase materials into the oil pan in sequence according to the mass fractions and start heating and stirring to obtain the oil phase; S93, according to the mass fraction, when the temperature of the water phase and the oil phase reaches 80°C, stop heating, pump the oil phase into the water phase and homogenize for 5-10 minutes, then cool to 60-65°C, add 20% sodium hydroxide water into the reactor, stir and keep warm under vacuum for 20 minutes; S94. After the heat preservation is completed, when the temperature is cooled to 44-45°C, the remaining materials are added into the reactor according to the mass fractions, stirred until completely dispersed, and then cooled to 32-35°C, the materials are discharged to obtain the cellulite firming cream.

[0019] In summary, the present application includes at least one of the following beneficial technical effects: 1. Gentle formula without irritation: The addition of anti-allergic agents (such as dipotassium glycyrrhizinate and Runfuyi) effectively reduces skin inflammation and allergic reactions, ensuring the mildness of the product. Dipotassium glycyrrhizinate exerts anti-inflammatory and anti-allergic effects by inhibiting the increase of white blood cells and preventing the release of histamine, while Runfuyi further protects the skin from free radical damage with its antioxidant, moisturizing and soothing properties, maintains the skin's moisturizing system, and reduces skin discomfort.

[0020] 2. High stability: Through the scientific proportion of water phase, oil phase and additive phase, the product has good physical and chemical stability. For example, the synergistic effect of 1618 alcohol and emulsifiers and other ingredients ensures the long-term stability of the product.
