[0002] As time goes by, extreme environments appear from time to time on Earth, and the skin is also suffering from damage caused by seasonal and environmental changes. Recently, the efficacy of cosmetics has gradually become diversified, with whitening, sun protection, moisturizing, anti-aging, anti-dullness and concealer products being continuously updated.

[0003] However, research on consumer skin problems found that 40%-50% of consumers believe that dry skin is the main problem of their body skin. Dryness can cause rough skin, enlarged pores, reduced metabolism, melanin immersion, and in severe cases, fine lines, cracks, and peeling.

[0038] In order to make the invention purpose, technical scheme and beneficial technical effect of the present application clearer, the present application is further described in detail below in conjunction with the embodiments. It should be understood that the embodiments described in this specification are only for explaining the present application, not for limiting the present application.

[0039] For simplicity, only some numerical ranges are explicitly disclosed herein. However, any lower limit can be combined with any upper limit to form an unambiguous range; and any lower limit can be combined with other lower limits to form an unambiguous range, and any upper limit can be combined with any other upper limit to form an unambiguous range. In addition, although not explicitly stated, each point or single value between the range endpoints is included in the range. Thus, each point or single value can be combined with any other point or single value as its own lower limit or upper limit or with other lower limits or upper limits to form an unambiguous range.

[0040] In the description herein, when a composition is described as containing, comprising or including specific components, or when a process is described as containing, comprising or including specific process steps, it is expected that the composition of the present application also consists essentially of or consists of the components, and the process of the present application also consists essentially of or consists of the process steps.

[0041] The use of the terms "including," "comprising," "containing," and "having" should generally be interpreted as open ended and non-limiting unless expressly stated otherwise.

[0042] In the description of this article, it should be noted that, unless otherwise specified, “above” and “below” are inclusive of the number itself, and the “multiple” in “one or more” means more than two.

[0043] The above-mentioned summary of the invention of the present application is not intended to describe each disclosed embodiment or each implementation in the present application. The following description more specifically illustrates exemplary embodiments. In many places throughout the application, guidance is provided by a series of examples, which can be used in various combinations. In each example, enumeration is only used as a representative group and should not be interpreted as exhaustive.

[0044] Many moisturizing compositions have poor long-term moisturizing effects. For example, only the moisturizing effect within 8 hours is tested, and the moisturizing effect of 2-8 hours shows a downward trend. It can be inferred that the long-term moisturizing effect needs to be improved. For example, the moisturizing composition is mainly water, which only has a short-term moisturizing effect. The composition does not mention water-locking substances, and the moisturizing mechanism is single and not comprehensive. For example, only the active ingredients of the extract are used to achieve a single-dimensional moisturizing effect, and the moisturizing effect is average.

[0045] In view of this, the inventors have conducted a lot of experimental research and demonstration, and provided a moisturizing composition and its application, a foundation liquid and its preparation method in the present application. In the embodiment of the first aspect of the present application, the moisturizing composition is provided, comprising the following components in parts by weight:

[0046] Thermal agent, 1 part; and the following, all based on 1 part of thermal agent: film-forming agent, 0.4-10 parts; oil, 2-20 parts; polyol, 4-60 parts; wherein the thermal agent includes one or a combination of ginger extract and cinnamon extract; the film-forming agent includes one or more of tremella polysaccharide, water-soluble chitosan, lactobacillus fermentation lysate and lotus placenta extract.

[0047] The moisturizing composition provided in the present application includes a certain ratio of thermal sensing agent, film-forming agent, oil and polyol, which can replenish intercellular lipids, soften the skin, promote the absorption of active substances, accelerate the proliferation and differentiation of keratinocytes (HACAT cells) in epidermal cells, secrete natural moisturizing factors, make the water and oil between cells in a balanced state, and form a soft film on the skin surface to reduce the loss of water and oil between cells. Multiple dimensions such as cell level, skin water content and water loss rate work together to maintain water-oil balance to improve the moisturizing effect.

[0048] Furthermore, the present application limits the types of thermal agents and film-forming agents. The inventors found that the thermal agents of the present application are selected from one or a combination of ginger extract and cinnamon extract, and the film-forming agents are selected from one or more of tremella polysaccharides, water-soluble chitosan, lactobacillus fermentation lysate and lotus placenta extract. Compared with other plant extracts such as cinnamon extract and other film-forming substances such as kelp extract, the types of thermal agents and film-forming agents of the present application can play a better synergistic role in the formula of the present application, and the moisturizing effect is significantly improved.

[0049] At the same time, compared with the combination of any two or three of the components, the combination of the four substances in the moisturizing composition of the present application not only has better long-term moisturizing effect, but also has better anti-wrinkle, anti-dullness, makeup lasting effect, product extensibility and skin feel when applied to liquid foundation, thereby improving the overall use effect of the moisturizing product.

[0050] Moisturizing Mechanism During epidermal differentiation, natural moisturizing factor (NMF) is formed by degrading histidine-rich filaggrin. NMF mainly includes amino acids, carboxylpyrrolidone acid, lactic acid, urea, glucose and mineral ions. It exists between cells and acts as an "adhesive" to absorb water molecules and prevent skin moisture loss. There are also many water-controlling structures in the skin. In addition to the stratum corneum, there are also hydration-related water transport proteins such as aquaporin-3 and tight junction proteins. These proteins form a sealing layer that can block the gaps between cells, thereby controlling the loss of water from cells to the outside.

[0051] The thermal agent of the present application is also called a heat-generating agent. Adding a thermal agent to cosmetics can make the product produce a strong sense of heat on the skin, promote blood circulation, make the human body feel comfortable, and promote the proliferation and differentiation of keratinocytes in epidermal cells to promote the secretion of natural moisturizing factors. The film-forming agent of the present application has viscosity and can form a soft film, forming a film on the surface of the skin to prevent water loss and increase the moisture content of the epidermis. The oil of the present application can soften the skin and enable active ingredients to enter the skin to play a role. At the same time, it replenishes intercellular lipids, improves skin softness, relieves the tightness caused by dryness, and prevents water loss, achieving the effect of nourishing the skin with oil. The polyol of the present application has a small molecular weight and strong permeability. It can easily enter keratinocytes, absorb moisture from the surrounding environment, increase the water content of the stratum corneum, and play an exogenous moisturizing effect.

[0052] The present application can also optimize the weight percentages of the thermal sensitizer, film former, oil and polyol to obtain a composition with better moisturizing effect. In some embodiments, the moisturizing composition includes the following components in weight percentages: thermal sensitizer, 1 part; and, based on 1 part of thermal sensitizer: film former, 1.5 to 4 parts; oil, 5 to 7 parts; polyol, 12 to 25 parts.

[0053] In some embodiments, the oil comprises one or a combination of jojoba fat and GTCC.

[0054] In some embodiments, the polyol includes one or more of 1.3-butanediol, 1.2-pentanediol, glycerol, and dipropylene glycol.

[0055] It is not intended to be limited by any theory or explanation, especially the combination of the above-mentioned types of thermal agents, film-forming agents, oils and polyols has a better effect and can obtain a more ideal moisturizing effect. For example, after replacing the thermal agent in the present application with cinnamon extract, the film-forming agent with marine algae such as kelp extract, and the oil with macadamia seed oil polyglycerol-6 ester tris-ester, the moisturizing effect obtained is not as good as the composition of the present application. It can be seen that the formula of the moisturizing composition of the present application is a combination with good matching effect carefully selected by the inventor after a large number of experimental studies.

[0056] In some embodiments, the moisturizing composition satisfies at least one of the following characteristics:

[0057] a. The thermal agent includes ginger extract and cinnamon extract in a mass ratio of 1:(2-5);

[0058] b. The film-forming agent comprises Tremella polysaccharide, water-soluble chitosan, Lactobacillus fermentation lysate and lotus placenta extract in a mass ratio of 1:(0.2-1):(0.5-1.5):(2-5), optionally 1:(0.8-1.0):(0.5-1.5):(2-4);

[0059] c. The oil includes jojoba fat and GTCC in a mass ratio of 1:(0.5-4), and 1:(0.6-3.5) is optional;

[0060] d. The polyol includes 1.3-butanediol, 1.2-pentanediol, glycerol and dipropylene glycol in a mass ratio of 1:(0.5-1):(0.5-1):(1-1.5).

[0061] The inventors have found that when the thermal sensitizing agent, film-forming agent, oil and polyol are within the above ratio range, the moisturizing effect is more excellent.

[0062] For example, when the thermal agent includes ginger extract and cinnamon extract in a mass ratio of 1:(2-5), compared with a single ginger extract or cinnamon extract, the thermal agent within the above mass ratio range can significantly improve cell vitality and increase the content of cell moisturizing factor HA, and only a small amount is required to achieve the effect of a single large dose of ginger extract or cinnamon extract, with significant moisturizing effect.

[0063] When the film-forming agent includes Tremella polysaccharide, water-soluble chitosan, lactobacillus fermentation lysate and lotus placenta extract in a mass ratio of 1:(0.2-1):(0.5-1.5):(2-5), the film-forming agent composition within this mass ratio range can form a soft film on the skin surface in a shorter time. The soft film has better compatibility with the skin and can be more gentle and non-irritating while improving the moisturizing effect.

[0064] When the oil includes jojoba fat and GTCC in a mass ratio of 1: (0.5-4), the mixed oil has a better moisturizing effect than a single oil, and can adapt to more different types of skin, and can also reduce the amount of oil added.

[0065] In an embodiment of the second aspect of the present application, there is provided a use of the moisturizing composition provided in the first aspect of the present application in cosmetics or skin care products, wherein the addition amount of the moisturizing composition is 5% to 15% of the total mass of the cosmetics or skin care products.

[0066] In an embodiment of the third aspect of the present application, a liquid foundation is provided, comprising the moisturizing composition provided in the first aspect of the present application.

[0067] In some embodiments, the liquid foundation includes: 5% to 15% of a moisturizing composition; and: 10% to 20% of an emulsifier and a silicone polymer, 5% to 15% of disteardimonium hectorite, 1% to 5% of fruit fat, 3% to 9% of isoparaffin, 1% to 5% of an inorganic salt, 1% to 5% of a preservative, 15% to 25% of a color powder, and 20% to 45% of water.

[0068] Without intending to be limited by any theory or explanation, the moisturizing composition combined with the above-mentioned types of components can form a liquid foundation with good moisturizing effect, anti-wrinkle, anti-dullness, long-lasting effect, extensibility and skin feel.

[0069] In some embodiments, the liquid foundation satisfies at least one of the following characteristics:

[0070] e. Emulsifiers and silicone polymers include one or more of PEG-10 dimethicone, lauryl PEG-9 polydimethylsiloxyethyl dimethicone, dimethicone and cyclopentasiloxane;

[0071] f. Fruit fats include one or more of avocado oil, mango oil and grape seed oil;

[0072] g. isomeric alkanes include one or a combination of isohexadecane and isododecane;

[0073] h. Inorganic salts include one or more of sodium chloride, potassium chloride and sodium sulfate;

[0074] i. Preservatives include one or more of phenoxyethanol, chlorphenesin and potassium benzoate;

[0075] j. The color powder includes one or more of zinc oxide, color powder and titanium dioxide.

[0076] In an embodiment of the fourth aspect of the present application, there is provided a method for preparing the liquid foundation according to the third aspect of the present application, comprising:

[0077] Mixing the emulsifier and the silicone polymer, disteardimonium hectorite, fruit fat, isoparaffin and color powder to obtain a first mixture;

[0078] Dissolving an inorganic salt, a moisturizing composition and a preservative in water to obtain a second mixture;

[0079] The second mixture is mixed evenly with the first mixture to obtain a liquid foundation.

[0080] In some embodiments, a method for preparing a liquid foundation comprises: stirring an emulsifier and a silicone polymer, disteardimethylammonium hectorite, fruit fat, isoparaffin, and a color powder at a rotation speed of 4000 to 6000 rpm / min for 5 to 20 minutes to obtain a first mixture;

[0081] dissolving an inorganic salt, a moisturizing composition and a preservative in water to obtain a second mixture;

[0082] The second mixture and the first mixture are stirred at a rotation speed of 3000-4000 rpm min for 5-10 min to obtain a liquid foundation.

[0083] Example

[0084] The following examples more specifically describe the disclosure of the present application, which are intended for illustrative purposes only, as it will be apparent to those skilled in the art that various modifications and variations are possible within the scope of the disclosure of the present application. Unless otherwise stated, all parts, percentages, and ratios reported in the following examples are by weight, and all reagents used in the examples are commercially available or synthesized according to conventional methods and can be used directly without further processing, and the instruments used in the examples are commercially available.

[0085] Example 1

[0086] This embodiment discloses a moisturizing composition, comprising the following components in parts by weight:

[0087] 2 parts of ginger extract, 27 parts of 1.3-butylene glycol, 5 parts of lotus placenta extract and 9 parts of water-soluble GTCC.

[0088] The specific formulas of the moisturizing compositions of various embodiments and comparative examples are shown in Table 1 below.

[0089] Table 1:

[0092]

[0093] Test Section

[0094] a.Hacat cell viability test

[0095] Keratinocytes are the main components of epidermal cells and play an important role in maintaining the normal structure and function of the skin. Keratinocytes are "bricks", the connections between cells are "rebars", and the lipids between cells are "mortar". This structure forms a natural protective barrier for human skin. This "wall" can not only block bacteria and dust from the outside, but also block some short-wave ultraviolet rays UVB from entering the skin and destroying skin cells. While blocking external invasion, it can also lock in skin moisture, prevent water loss, and play a moisturizing role.

[0096] MTT test principle: The yellow salt MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) can be reduced to blue formazan by succinate dehydrogenase secreted by the mitochondria of normal living cells. Formazan is a water-insoluble precipitate that can be dissolved by DMSO and has a significant absorption peak at 570nm, while dead cells do not have this effect. Therefore, the MTT method is often used to test cell viability and characterize cell proliferation.

[0097] Test method: In a 96-well plate cell culture dish, 4 -10 5 cells / ml were inoculated in DMEM medium containing 10% serum, and a total of 100ul was cultured for 24h, with a cell density of about 55%-70%. The medium was discarded and rinsed twice with sterile buffer solution for later use. The drug was administered, and the sample to be tested was diluted twice with serum-free medium and cultured for another 24h. 20ul MTT was added, cultured in the dark for 2h, the medium was discarded, 100ul isopropanol was added, 100rpm, 30min, and the absorbance of each well was measured at 570nm. The blank control group was replaced by serum-free medium without adding the sample to be tested. The measurement was performed in parallel 6 times, and the results were averaged. Cell activity calculation method:

[0098] Cell viability 100% = sample absorbance / blank control group absorbance * 100%

[0099] The heat-sensing agent ginger extract, cinnamon extract, and a mixture of ginger extract and cinnamon extract were respectively taken for cell viability test. The test results are as follows Figure 1 shown.

[0100] from Figure 1 It can be seen that compared with the blank group, the HACAT cell activity of the sample with added thermal agents was significantly improved, indicating that the thermal agents ginger extract, cinnamon extract, ginger extract and cinnamon extract can promote cell proliferation.

[0101] b. HA content determination

[0102] The sample with the concentration corresponding to about 85% of the cell viability was taken to test the HA content in HACAT cells. The test results are shown in Table 2. The test method is to place the cells in a 24-well plate at 10 4 -10 5 cells / ml were inoculated in a DMEM medium containing 10% serum, and a total of 500ul was cultured for 24 hours, and the cell density was about 55-70%. The medium was discarded and rinsed twice with a sterile buffer solution for later use. After administration and culturing for 24 hours, the cells were transferred to a 1.5ml centrifuge tube and centrifuged at 12000rpm for 10 minutes, and the supernatant was reserved for testing.

[0103] Table 2:

[0104]

[0105]

[0106] As can be seen from Table 2, the thermal agent not only promotes cell proliferation, but also promotes the increase of HA content of cell moisturizing factor, increases the moisture content of the skin, and has a significant moisturizing effect. In particular, the mixed extract of cinnamon and ginger can significantly increase the HA content of cells with a small amount.

[0107] c. Clinical moisturizing composition moisturizing effect test

[0108] Test indicators: Instrument used TM300, Courage & Khazaka, Germany, tests the transepidermal water loss (TEWL) of the skin. The skin water loss data is indirectly measured through two pairs of sensors inside the probe, and the unit is g / m 2 h. The larger the value, the higher the transepidermal water loss rate per unit time. Figure 2 (part) and shown in Table 3 below.

[0109] Table 3:

[0110]

[0111]

[0112] Use the instrument CM825, Courage & Khazaka, Germany, tests the moisture content of the skin. Based on the different dielectric constants of water and other substances, the moisture content of the stratum corneum is measured through the change in capacitance. The larger the value of the moisture content of the stratum corneum, the higher the moisture content of the stratum corneum. The test results are as follows Figure 3 (part) and shown in Table 4 below.

[0113] Table 4:

[0114]

[0115]

[0116] Test method: The left side of the subject's face was treated with a product containing the new moisturizer, and the right side was treated with a product without the new moisturizer. The only difference between the two products was whether the moisturizer was added. The moisturizer weight ratio in the product without moisturizer was replaced by deionized water. The face of the subject was tested before the subject used the product and after using the product for 28 days. The subject lived a normal life during the entire test process. Before each test, the subject was required to sit quietly in a constant temperature and humidity room with a temperature of 21±1℃ and a relative humidity of 50±10% for 20 minutes.

[0117] From the above test results, it can be seen that the transepidermal water loss of the embodiment is significantly reduced, and the skin water content is significantly increased, indicating that this moisturizing composition has a significant moisturizing effect. At the same time, it is analyzed that Comparative Examples 1 and 3 affect transepidermal water loss, and Comparative Examples 2 and 4 affect the skin water content. Therefore, the four components of the moisturizing composition complement each other and work together to achieve a moisturizing effect. The lack of one of the four will affect the moisturizing ability. Comparative Examples 5 and 6 have poor synergistic effects and poor moisturizing effects due to their different types.

[0118] d. Skin feel clinical test

[0119] The moisturizing compositions of different embodiments and comparative examples were added to a flawless long-lasting liquid foundation, and healthy women aged 20-45 years old from the company were randomly selected for a test period of 28 days. The liquid foundation was used for normal makeup every day, and the skin feel of the liquid foundation was evaluated during use. At the same time, the VISIA device was used to detect wrinkle changes on subjects with wrinkles. The blank group did not add this highly moisturizing composition, and replaced the volume ratio with water. The evaluation standard is 1-5 points, the results are averaged, and integers are retained. The larger the value, the better the effect; the smaller the floating powder value, the better. The skin feel test results are shown in Table 5. See the wrinkle test results. Figure 4 .

[0120] The formulated flawless long-lasting makeup foundation comprises the following components in parts by weight: Phase A: 2.4 parts by weight of PEG-10 polydimethicone, 1.6 parts by weight of lauryl PEG-9 polydimethylsiloxyethyl polydimethicone, 1 part by weight of polydimethicone, 9.4 parts by weight of cyclopentasiloxane, 7 parts by weight of disteardimonium hectorite, 2 parts by weight of avocado tree (Butyrospermum Parkii) fruit fat, and 6 parts by weight of isohexadecane; Phase B: 31.6 parts by weight of water, 1.5 parts by weight of sodium chloride, 7 parts by weight of a moisturizing composition, and 1 part by weight of phenoxyethanol; Phase C: 4.5 parts by weight of zinc oxide and 15 parts by weight of color powder.

[0121] The preparation method of a flawless long-lasting makeup liquid foundation comprises: stirring phase A and phase C at a rotation speed of 5000 rpm / min for 10 minutes to obtain a first mixture; heating phase B to 70-80°C to completely dissolve it to obtain a second mixture; stirring the second mixture and the first mixture at a rotation speed of 3000 rpm / min for 10 minutes to mix them evenly, cooling them to room temperature, and degassing to obtain a liquid foundation.

[0122] Table 5:

[0123]

[0124]

[0125] As can be seen from the data in the table, the foundation liquid with the moisturizing composition can increase the skin feel and ductility of the facial base makeup product, improve the floating powder situation so that the product is not easy to remove makeup, and has a significant moisturizing effect. The lack of obvious anti-dullness effect may be related to the formula system, and the formula needs to be adjusted. Taking the photos of the above 4 subjects as an example, the wrinkles of many subjects were significantly improved, indicating that the moisturizing composition of the present application can also improve the wrinkle situation, so that the makeup product has a certain skin care effect, and achieve the "makeup to nourish the skin" effect currently expected by consumers.
