Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cosmetics, more particularly, it relates to a liquid makeup fixing cream and a preparation method thereof. BACKGROUND

[0002] As a special liquid product in the cosmetic market, the liquid makeup fixing cream is also a color cosmetic product integrating moisturizing, nourishing and makeup fixing. It is mainly used to relieve problems such as powder sticking and floating. Its core function is to make the makeup more closely adhere to the skin through moisturizing and water-locking technology, to replace the traditional skincare steps and improve the fit of the base makeup. The liquid makeup fixing cream spray presents a spray texture, can quickly penetrate the skin and form a protective film after use, and has the functions of moisturizing and water-locking.

[0003] At present, the related liquid makeup fixing cream spray product generally has a pure water formula system. Such a system has a short moisturizing time, and the face will appear dry after use. In this case, the problem can only be solved by adding oil to the formula. However, after adding oil to the general pure water formula, the material will first appear stratification. If other means are used to solve this problem, a corresponding thickening agent can be added to the water phase to increase the viscosity to ensure that the stability of the material will not stratify.

[0004] However, the above technology often leads to poor atomization effect, resulting in large droplet size of the spray, which not only reduces the coverage range of the spray and requires multiple re-spraying to achieve the desired effect, but also makes it difficult for the mixed raw material components to uniformly adhere to the skin surface. In addition, large droplets can block pores or cause local irritation, especially for people with sensitive skin.

[0005] Therefore, there is an urgent need to propose a solution to solve the above technical problems. SUMMARY

[0006] In order to improve the atomization effect of the liquid makeup fixing cream spray product when applied, to bring excellent moisturizing effect, and to ensure that the phenomenon of dryness and patchy powder sticking does not easily occur, the present application provides a liquid makeup fixing cream and a preparation method thereof.

[0007] In a first aspect, the present application provides a liquid makeup fixing cream, which adopts the following technical solution: A liquid makeup fixing cream is made of raw materials containing the following weight parts: 95-105 parts of water; 4-25 parts of a moisturizing agent; 0.1-2 parts of a skin conditioning agent; 0.5-1 part of an antioxidant; 0.2-5 parts of polyglyceryl-10 laurate; 1.1-12 parts of an emollient; The emollient is a combination of one or more of caprylic / capric triglyceride, isononyl isononanoate and dimethicone.

[0008] By adopting the above technical scheme, in the liquid stick cream, the polyhydroxy structure of polyglyceryl-10 laurate can reduce the liquid surface tension, promote the formation of uniform and fine mist droplets, enhance the skin coverage, and has solubilizing and stabilizing effects, which can prevent the separation of oil phase (emollient) and water phase in the formula, and ensure uniform distribution of components during spraying; at the same time, the hydrophilic structure of polyglyceryl-10 laurate can absorb moisture, and can also form a hydration film with the humectant, reduce transdermal water loss, and has high mildness. In the emollient, caprylic / capric triglyceride has good skin compatibility, can enhance the hydration degree of stratum corneum, and its light oil characteristics can improve the extensibility, help the spray spread quickly to form a film, and avoid local accumulation of powder; isononyl isononanoate can adjust the viscosity of the formula, make the spray feel light and not sticky, reduce the oil light, and together with polyglyceryl-10 laurate, it can stabilize the emulsion system and avoid uneven spraying; dimethicone can reduce liquid resistance, make the atomization more delicate, and form a breathable silicone film to effectively lock water. Using a combination of one or more of caprylic / capric triglyceride, isononyl isononanoate and dimethicone as an emollient, and compounding with polyglyceryl-10 laurate, not only can form a double water-locking network, but also can ensure uniform dispersion of spray components, and the spray droplet size is significantly reduced, which can significantly improve the atomization effect of liquid stick cream spray product application, to bring excellent moisturizing effect, and further ensure that the phenomenon of dry and uneven powder is not easy to occur.

[0009] Preferably, the emollient is composed of the following weight parts of raw materials: Caprylic / capric triglyceride 1-10 parts; Isononyl isononanoate 0.1-2 parts.

[0010] By adopting the above technical scheme, the light property of caprylic / capric triglyceride and the low viscosity property of isononyl isononanoate synergistically reduce the overall viscosity of the formula, and can adapt to the spray device, which is beneficial to achieve better uniform and delicate atomization effect, and also can form a complementary moisture-stable film with polyglyceryl-10 laurate, thereby achieving excellent "instant skin sticking-long-term moisturizing-stable makeup" triple effect, and finally obtaining a liquid stick cream with better application quality.

[0011] Preferably, the humectant is a combination of one or more of glycerin, butylene glycol, propylene glycol and 1,2-pentanediol.

[0012] The humectant is composed of the following weight parts of raw materials: Glycerin 1-10 parts; Butanediol 1-10 parts; 1,2-pentanediol 2-5 parts.

[0013] By adopting the above technical scheme, glycerol has strong hygroscopicity, adsorbs moisture in the environment through hydrogen bonding, increases the water content of the stratum corneum, relieves dryness and tightness, and cooperates with polyglyceryl-10 laurate to form a hydration film, prolonging the moisturizing time; the small molecular polyol structure of butanediol quickly penetrates, supplements the deep layer of skin moisture, reduces the sticky feeling of the formula, and also acts as a solvent to promote the dissolution and absorption of other active ingredients; 1,2-pentanediol can enhance the hydration capacity of the stratum corneum, assist in dissolving poorly soluble ingredients, improve the stability of the formula, and also has the functions of moisturizing and preservative enhancement, reducing the risk of sensitivity; the selection of the above moisturizing agents can form a "water absorption-locking-protection" triple network, and through the gradient effect of polyols, it realizes three-dimensional moisturizing from the epidermis to the deep layer, making the spray texture refreshing and easy to absorb, and thus obtaining a liquid body balm with better application quality.

[0014] Preferably, the skin conditioning agent is one or a combination of several of betaine, trehalose, erythritol, acetylchitosamine, galactose yeast cell lysate filtrate, and sodium lactate.

[0015] By adopting the above technical scheme, the skin conditioning agent can bring the effects of barrier repair, soothing and anti-sensitivity, and microecological balance, not only can promote the penetration efficiency of the moisturizing component, prolong the hydration time, but also can cooperate with polyglyceryl-10 laurate and emollients to stabilize the mixing system together, ensure the realization of excellent spray effect, and through enhancing the lipid structure between keratinocytes, repairing the damaged skin barrier due to environmental stimulation, reducing transdermal water loss, improving skin tolerance, regulating the bacterial flora environment on the skin surface, and inhibiting the excessive proliferation of harmful bacteria, etc. to ensure the excellent stability of the application effect of the liquid body balm.

[0016] Preferably, the antioxidant is one or a combination of several of p-hydroxyacetophenone, ferulic acid, tea polyphenol, ethylhexylglycerin, proanthocyanidin, and tocopherol.

[0017] By adopting the above technical scheme, the antioxidant can cooperate with polyglyceryl-10 laurate and emollients to enhance stability, maintain the stability of the mixing system, and capture free radicals generated by ultraviolet rays and environmental pollution, block the oxidation chain reaction, reduce the degradation of collagen and elastic fibers, and delay skin aging; the above types of antioxidants are suitable for the preparation of liquid body balm, and can bring the above excellent effects, and thus obtain a liquid body balm with excellent stability in application quality.

[0018] Preferably, the raw materials also add 0.5-3 parts by weight of functional additives, the functional additives consist of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid, and the weight ratio of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid is (3.2-5.8):1.

[0019] By adopting the above technical solution, the high molecular network structure of sodium hyaluronate salicylate can reduce the surface tension of the liquid, and cooperate with polyglyceryl-10 laurate to form uniform small droplets, thereby enhancing the spray diffusion; as a small molecule solubilizer, sodium pyrrolidone hydroxy acid can quickly capture moisture from the air to form a stable hydration layer, reduce the problem of uneven particle size caused by droplet evaporation, and further improve the atomization stability; when sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid are used together as functional additives, sodium hyaluronate salicylate forms a breathable moisturizing film on the skin surface, and sodium pyrrolidone hydroxy acid quickly penetrates into the stratum corneum to supplement water, forming a "surface water locking-deep water supplementing" double-effect barrier. At the same time, the combination of the two can significantly reduce the surface tension of the spray droplets, making the spray droplet size distribution more concentrated and less likely to cause spray droplet adhesion, thereby significantly improving the atomization effect. Therefore, by adding functional additives composed of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid, the overall application effect of the liquid body lotion can be significantly improved.

[0020] Preferably, the weight ratio of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid is 4.5:1.

[0021] By adopting the above technical solution, the above weight ratio of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid is used together, and the effect of the two is excellent, and a stable action system can be formed with polyglyceryl-10 laurate and emollients, thereby ensuring that the liquid body lotion has stable and good application quality.

[0022] In a second aspect, the present application provides a preparation method of a liquid body lotion, which adopts the following technical solution: A preparation method of a liquid body lotion, comprising the following steps: (1) Prepare raw materials containing water, moisturizing agent, skin conditioner, antioxidant, polyglyceryl-10 laurate and emollient according to the ratio; (2) Put the emollient in step (1) into a container and stir, then add the moisturizing agent, skin conditioner, antioxidant and polyglyceryl-10 laurate under stirring, mix, then add water and continue stirring, and finally perform high-pressure homogenization to obtain the liquid body lotion.

[0023] By adopting the technical scheme, the preparation method is simple in operation, suitable for large-scale industrial production, and each raw material is added step by step, which is beneficial to quality control and can ensure that the raw materials are fully combined, so that the liquid body lotion with excellent quality and stability is obtained.

[0024] In summary, the present application has the following advantages: 1. The present application uses polyglyceryl-10 laurate and emollients, which not only forms a double water-locking network, but also ensures uniform dispersion of spray components, and significantly reduces the particle size of spray droplets; when caprylic / capric triglyceride and isononyl isononanoate are used as emollients, the overall effect is better; therefore, the atomization effect of the liquid body lotion spray product can be significantly improved when applied, so as to bring excellent moisturizing effect, and to ensure that the phenomenon of dry and patchy powder is not easy to occur; 2. The present application adds a functional additive composed of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid, which not only forms a breathable moisturizing film on the skin surface with sodium hyaluronate salicylate and quickly penetrates into the stratum corneum with sodium pyrrolidone hydroxy acid to supplement water, forming a "surface water-locking-deep water-supplying" double-effect barrier, but also makes the spray droplet size distribution more concentrated, and is not easy to produce spray droplet adhesion, thereby bringing significant improvement in atomization effect, which is beneficial to obtain liquid body lotion with better application quality.

[0044] Comparative Example 4 A liquid stick cream, which differs from Example 10 in that polyglyceryl-10 laurate and emollients are not used in the raw materials.

[0045] Performance Test Test samples: The liquid stick creams obtained in Examples 1-16 are selected as test samples 1-16, and the liquid stick creams obtained in Comparative Examples 1-4 are selected as control samples 1-4.

[0046] Test method: (1) Average particle size of spray droplets test: The laboratory needs to control the temperature at 25°C and the humidity at 55%, avoid air flow interference, put the liquid stick cream into a special container for atomization instrument, the spray rate is 0.5 mL / min, the nozzle pressure of the atomization instrument is 0.5 MPa, use a laser particle size analyzer to record the particle diameter in real time, take the average value of the distribution as the average particle size of the spray droplets.

[0047] (2) Spray uniformity test: The laboratory needs to control the temperature at 25°C and the humidity at 55%, avoid air flow interference, put the liquid body cream into the special container of the atomizer, the spray rate is 0.5 mL / min, the nozzle pressure of the atomizer is 0.5 MPa; place three films with a size of 1 cm x 1 cm in the spray range, after spraying for 2 min, measure the deposition amount of the liquid body cream on the film, take the average value of the difference between the deposition amounts of the three films, and record it as the average deposition difference, and the larger the average deposition difference, the worse the distribution uniformity of the atomized liquid body cream.

[0048] (3) Moisturizing effect test: The laboratory needs to control the temperature at 25°C and the humidity at 55%, avoid air flow interference, select 10 subjects with healthy skin, aged 35-55, randomly divide them into 20 groups, half male and half female; use the liquid body cream for spray test, the amount used per person is 0.2 mL, after 1 h of use, use the Tewameter TM 300 probe of the German CK skin tester to measure the change value of the transdermal water loss, the change value of the transdermal water loss = (the water loss of the subject after 1 h of use - the initial value of the water loss of the subject before use) / the initial value of the water loss of the subject before use, take the average value of the test of two people in each group.

[0049] After the above tests are performed on the test samples 1-16 and the control samples 1-4, the test results are recorded in Table 4.

[0050] Table 4 Test results of test samples 1-16 and control samples 1-4 In combination with Examples 1-3 and Comparative Examples 1-3 and Table 4, it can be seen that by using the emollient composed of caprylic acid / capric acid triglyceride and isononyl isononanoate in combination with polyglyceryl-10 laurate, the spray droplet size of the liquid body cream during application can be significantly reduced, and the spray uniformity can be significantly improved, thereby the moisturizing effect can be significantly improved; if either of the emollient and polyglyceryl-10 laurate is used alone, although it can improve the corresponding effect, the improvement is limited, and the sum of the improvement effects brought by the two respectively is far less than the excellent improvement effect brought by the combination of the two; therefore, the emollient and polyglyceryl-10 laurate can have excellent synergistic effect in the liquid body cream, thereby significantly improving the atomization effect of the liquid body cream spray product during application, to bring excellent moisturizing effect, thereby ensuring that the phenomenon of dry and patchy powder is not easy to occur.

[0051] It can be seen from the combination of Examples 1, 4-5 and Examples 8-9 and Table 4 that if any one of caprylic / capric triglyceride and isononyl isononanoate is used alone as an emollient, the liquid body lotion will have obvious performance loss in the average particle size of spray droplets, the average difference in deposition amount and the change in transdermal water loss amount after the above tests, and thus the combination of caprylic / capric triglyceride and isononyl isononanoate as an emollient can bring more prominent corresponding effect.

[0052] It can be seen from the combination of Examples 1 and Examples 10-14 and Table 4 that the addition of the functional adjuvant composed of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid can further improve the atomization effect of the liquid body lotion spray product in application and bring better and excellent moisturizing effect. It can be seen from the combination of Examples 15-16 and Table 4 that if sodium hyaluronate salicylate or sodium pyrrolidone hydroxy acid is used alone, the improvement effect is effective, and from the performance of the average particle size of spray droplets, the average difference in deposition amount and the change in transdermal water loss amount measured above, the combination of sodium hyaluronate salicylate and sodium pyrrolidone hydroxy acid can bring a significant improvement effect of 1+1>2. It can be seen from the combination of Comparative Examples 3-4 and Table 4 that if the emollient and polyglyceryl-10 laurate are not used in the liquid body lotion, the improvement effect of the functional adjuvant will have obvious loss, and thus they have a synergistic effect, and thus a liquid body lotion with better application quality can be obtained.

[0053] The specific embodiments are merely an explanation of the present application, which is not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the Patent Law.
