Technical Field

[0001] The invention relates to the field of cosmetics, and in particular to an oil-controlling and soothing foundation liquid and a preparation method thereof. Background Art

[0002] There are many types of foundations on the market with different functions, which can easily make it difficult for consumers to choose. At the same time, with the worsening of environmental pollution and the faster pace of life, modern people have more oil and sebaceous gland problems on their skin surface than in the past, and their skin thickness has become thinner, and the number of people with sensitive skin has gradually increased. More and more urban people have skin sensitivity problems due to work pressure. Analysis of the purchasing behavior of consumers with sensitive skin found that they will pay more attention to the cost-effectiveness and immediate effect of soothing and repairing foundation.

[0003] Therefore, there is an urgent need in this field to develop a new type of liquid foundation that has both oil-control and soothing effects to solve the main problems of consumers with sensitive skin. Summary of the invention

[0004] The purpose of the present application is to provide an oil-controlling and soothing foundation liquid and a preparation method thereof, which can simultaneously achieve the effects of oil control and soothing.

[0005] In the first aspect, the present application provides an oil-controlling soothing liquid foundation, which adopts the following technical solution: An oil-controlling and soothing liquid foundation, characterized in that it comprises the following components in percentage by mass: 20-50% of an oil phase, 5-20% of a powder phase, 20-50% of an aqueous phase, and 1-10% of an effective ingredient phase; the oil phase comprises a skin conditioning agent A, the powder phase comprises a skin conditioning agent B, the aqueous phase comprises a skin conditioning agent C, and the effective ingredient phase comprises a skin conditioning agent D; Among them, the skin conditioner A is composed of butyl avocado oleate and tocopherol, the skin conditioner B is composed of yeast fermentation products and lauroyl lysine, the skin conditioner C is adenosine, and the skin conditioner D contains CalmYang composite plant anti-allergic agent.

[0006] By adopting the above-mentioned technical scheme, the liquid foundation of the present application compounds the skin conditioners in the oil phase, powder phase, water phase and functional ingredient phase, and has a good oil control and anti-allergy effect by inhibiting the activity of 5α-reductase, promoting skin barrier regeneration and inhibiting the synergistic effect of inflammatory factors. The experiment of the present application also confirmed that it will not cause allergic reactions and has a good oil control effect.

[0007] Optionally, the weight percentages of the skin conditioners are: skin conditioner A 0.1-1%, skin conditioner B 0.1-1%, skin conditioner C 0.01-0.1%, and skin conditioner D 0.1-2%.

[0008] By adopting the above technical solution and using an appropriate amount of skin conditioners, the effects of the skin conditioners can be better coordinated to achieve oil control and soothing effects.

[0009] Optionally, the oil phase further comprises an emulsifier, an emollient, a film former and a thickener.

[0010] Optionally, the emulsifier consists of a mixture of PEG-10 dimethicone, bis-PEG / PPG-14 / 14 dimethicone and dimethicone.

[0011] By adopting the above technical solution, double-PEG / PPG-14 / 14 polydimethylsiloxane and polydimethylsiloxane are compounded, and the emulsifying ability of the emulsifier is stronger, which can lock in the effective ingredients, achieve water-oil balance, and reduce oil secretion and allergic reactions.

[0012] Optionally, the film former is composed of a mixture of trimethylsiloxysilicate, acrylate / polytrimethylsiloxane methacrylate copolymer and polydimethylsiloxane.

[0013] By adopting the above technical solution, the acrylate / polytrimethylsiloxane methacrylate copolymer is compounded with polydimethylsiloxane to reduce the content of the acrylate / polytrimethylsiloxane methacrylate copolymer, the stickiness and heaviness of the skin feel can be reduced, the water-oil balance can be achieved, and the oil secretion and allergic reactions can be reduced.

[0014] Optionally, the powder phase further comprises a dispersant, an emollient, a colorant and a thickener.

[0015] Optionally, the aqueous phase further comprises a solvent, a humectant, a chelating agent and a stabilizer.

[0016] Optionally, the functional ingredient phase further comprises a preservative, an emollient, a skin feel regulator and a stabilizer.

[0017] Optionally, the skin conditioner D further comprises human pluripotent stem cell exosomes.

[0018] By adopting the above technical solution, pluripotent stem cell exosomes are added to the skin conditioner, which can form a thin film on the skin surface to lock in moisture, keep the skin hydrated, prevent moisture loss, and effectively relieve excessive oil secretion from sebaceous glands and prevent allergic reactions.

[0019] In a second aspect, the present application provides a method for preparing an oil-controlling and soothing foundation liquid, using the following technical solution: Step 1: Add the raw oil phase into the main pot in different batches; Step 2: Mix the raw powders evenly, grind them 3 times, put them into the main pot, and heat the main pot to 78-82℃; Step 3: Add the raw material water phase into the water phase pot and heat to dissolve at 78-82°C; Step 4: Keep the temperature at 78-82°C, slowly pour the water phase into the main pot (mixture of powder phase and oil phase), homogenize at 2500-3000rpm, and after adding the materials, homogenize at 4500-5000rpm for 8-10min; Step 5: Cool down to below 45°C, add the active ingredient phase raw materials, and homogenize at 4500-5000rpm until the appearance and color of the material are uniform; Step 6: Match colors, vacuum, and serve.

[0020] By adopting the above technical solution, each phase is mixed evenly in steps, especially by mixing the oil phase and the powder phase first, so that the colorant can be fully mixed and dispersed, and polydimethylsiloxane and the like can carry more colorant, thereby achieving oil control and soothing effects.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. It can play a good effect on the anti-allergy and allergy prevention of sensitive skin and the treatment of hormone-dependent dermatitis; 2. Has long-lasting oil control effect; 3. It is especially suitable for oily and sensitive skin, promoting the regeneration of the epidermal barrier and significantly improving the damage of the sebum membrane and the disorder of skin flora. DETAILED DESCRIPTION

[0022] The present application is described below by way of examples, but the present application is not limited thereto. The experimental methods shown in the following examples are conventional methods unless otherwise specified. The reagents and materials shown without indicating the manufacturer are conventional products that can be purchased commercially.

[0023] Example 1 An oil-controlling and soothing liquid foundation comprises the following components by weight percentage: Oil phase: Powder phase: Aqueous phase: Effective ingredient phase (its skin conditioning agent is also called "CalmYang complex plant anti-allergic agent"): A method for preparing an oil-controlling and soothing liquid foundation comprises the following steps: Step 1: Add raw materials 1-2 in the oil phase into the main pot, stir and dissolve raw materials 3-7 in advance and then add them into the main pot, then add raw materials 8-10 into the main pot; Step 2: Mix raw materials 11-18 in the powder phase evenly, grind 3 times, put into the main pot, and heat the main pot to 78-82℃; Step 3: Add raw materials 19-24 in the water phase into the water phase pot and heat to dissolve at 78-82°C; Step 4 (emulsification): Keep the temperature at 78-82°C, slowly pour the water phase into the main pot (mixture of powder phase and oil phase), homogenize at 2500-3000rpm, add all the materials for about 1min, then homogenize at 4500-5000rpm for 8-10min; Step 5: Cool down to below 45°C, add 25-29 of the active ingredient phase raw materials, and homogenize at 4500-5000rpm for 3-5min until the appearance and color of the material are uniform; Step 6: Match colors, vacuum, and serve.

[0024] Example 2 An oil-control soothing liquid foundation, which differs from Example 1 in that: the skin conditioning agent 29 of the functional ingredient phase also contains human pluripotent stem cell exosomes (the preparation method refers to Example 1 of CN110123838B), accounting for 1% of the mass of the skin conditioning agent of the functional ingredient (reducing the corresponding amount of water), and the rest is the same as Example 1.

[0025] Comparative Example 1 The difference from Example 1 is that the skin conditioning agent is not contained in the oil phase, and the reduced content is supplemented by a solvent. The rest is the same as Example 1.

[0026] Comparative Example 2 The difference from Example 1 is that the skin conditioning agent is not contained in the powder phase, and the reduced content is supplemented by a solvent. The rest is the same as Example 1.

[0027] Comparative Example 3 The difference from Example 1 is that the water phase does not contain a skin conditioning agent, and the reduced content is supplemented by a solvent. The rest is the same as Example 1.

[0028] Comparative Example 4 The difference from Example 1 is that the skin conditioning agent among the effective ingredients is not contained, and the reduced content is supplemented by a solvent. The rest is the same as Example 1.

[0029] Comparative Example 5 The difference from Example 1 is that the oil phase film former does not contain polydimethylsiloxane, but only contains 1% of acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer.

[0030] Comparative Example 6 The difference from Example 1 is that the oil phase emulsifier does not contain polydimethylsiloxane, and only contains 1% of bis-PEG / PPG-14 / 14 polydimethylsiloxane.

[0031] Performance Testing 1. Oil control effect test 80 test volunteers were selected, with 10 people in each group, to evaluate the long-term 28-day skin oil content of Examples 1-2 and Comparative Examples 1-6, and calculate T0 and T 28d The average value and difference of skin oil content are measured, and relevant judgments are made based on the difference.

[0032] T0 detection: the subject came, washed the entire face with clean water, wiped the skin with dry tissue after washing, sat in the laboratory at 21±1℃ and 50±10%RH for 20 minutes, and the laboratory technician measured the skin oil index of the subject with the skin oil content tester Sebumeter SM 815; T 28d Testing: Laboratory technicians instruct subjects to use the product according to the test requirements and product usage instructions. The test samples are used continuously for 28 days. The subjects use it every other day, and the oil content is tested according to the T0 method 28 days after use.

[0033] Table 1 Long-term oil control test results Combining Example 1 and Example 2 with Table 1, it can be seen that the pluripotent stem cell exosomes in the present application can form a thin film on the skin surface, lock in moisture, keep the skin hydrated, prevent moisture loss, and effectively relieve excessive oil secretion from sebaceous glands.

[0034] Combining Example 1 and Comparative Example 5 with Table 1, it can be seen that the acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer in the film-forming agent of Comparative Example 5 is not compounded with polydimethylsiloxane, and the oil secretion change rate is significantly greater than that of Example 1, indicating that the oil secretion of Comparative Example 5 is higher than that of Example 1. This may be because the increase in the content of acrylic acid (ester) / polytrimethylsiloxane methacrylate copolymer will cause the skin to feel sticky and heavy, and excessive oil secretion occurs after the water-oil imbalance.

[0035] Combining Example 1 and Comparative Example 6 with Table 1, it can be seen that the bis-PEG / PPG-14 / 14 polydimethylsiloxane in the emulsifier of Comparative Example 6 is not compounded with polydimethylsiloxane, and the oil secretion change rate is significantly greater than that of Example 1, indicating that the oil secretion of Comparative Example 6 is higher than that of Example 1, which may be because the emulsification ability of the uncompounded emulsifier is insufficient, the effective ingredients cannot be locked, and excessive oil secretion occurs after the water-oil imbalance.

[0036] Combining Example 1 and Comparative Examples 1-4 and Table 1, it can be seen that the oil secretion change rate of Comparative Examples 1-4 is significantly greater than that of Example 1, indicating that the absence of any skin conditioning agent will lead to a decrease in synergistic effect, and it is impossible to effectively inhibit the activity of 5α-reductase and promote skin barrier regeneration, resulting in excessive oil secretion.

[0037] 2. Allergy-relieving effect detection Human skin patch test, trial method according to: "Cosmetic Safety Technical Specifications" (2015 edition). Select a suitable patch tester, use the closed patch test method, put 8 groups of samples (corresponding to Examples 1-2 and Comparative Examples 1-6) into the patch tester, the control hole is blank, use the palm of your hand to gently press it to evenly apply it on the skin, wait for 10 minutes, then cover the sample and the blank control on the inner side of the forearm of the subject where the irritant has been applied, remove the patch tester and wait for 30 minutes, observe the skin reaction after the indentation disappears, observe the skin reaction according to the standards in Table 2 after 24h and 48h, and record the observation results.

[0038] Table 2 Classification criteria for adverse skin reactions in skin occlusive patch tests Table 3 Human skin patch test results It can be seen from Examples 1-2 and Comparative Examples 1-4 and Table 3 that the liquid foundation prepared by the present application does not cause allergic reactions, and all of them are negative; this indicates that the skin conditioning agents in the oil phase, powder phase, water phase and functional ingredient phase are compounded, and a good anti-allergic effect is achieved by inhibiting the activity of 5α-reductase, promoting skin barrier regeneration and inhibiting the synergistic effect of inflammatory factors; at the same time, it can also be seen that the anti-allergic ability of the liquid foundation is significantly reduced without the skin conditioning agent in any phase, which is far less than the excellent effect brought by the four compoundings.

[0039] It can be seen from Example 1 and Comparative Examples 5-6 and Table 3 that the lack of polydimethylsiloxane in the film former and emulsifier causes the skin to feel sticky and heavy, leading to an imbalance of water and oil, and the skin barrier function may be damaged, making allergic reactions more likely to occur.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent implementations or changes made according to the present application should be included in the protection scope of the present application.
