Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cosmetics, in particular to a lyophilized foundation liquid and a preparation method thereof. BACKGROUND

[0002] Foundation is a common makeup product, mainly used for modifying facial skin, covering blemishes, evening out skin tone, and also protecting the skin to some extent, and is the "foundation" of makeup. There are various types of foundation, from texture, form to function, which are classified differently to meet different skin types and makeup needs.

[0003] Common types of foundation include foundation liquid, foundation cream, powder cake, air cushion foundation, etc. Among them, foundation liquid is popular among consumers because of its excellent makeup holding ability and concealing effect. In the prior art, a flawless whitening foundation liquid is disclosed, which comprises the following raw materials: bee lyophilized powder, vitamin E, capric acid triglyceride, vaseline, beeswax, mineral oil, silicone oil, isooctyl palmitate, amino acid, kaolin, precipitated calcium carbonate, deionized water, preservative, essence. The obtained foundation liquid has no irritation to the skin, and after use, it feels comfortable and soft, and has no greasy feeling, and has obvious effects of covering blemishes and brightening skin color.

[0004] However, the water content of the above components is limited, and the product shape tends to be a thick emulsion with high viscosity, which is too thick and heavy, and is not easy to spread when applying makeup, and is not easy to spread evenly, and is not smooth enough, and is prone to makeup dissolution. SUMMARY

[0005] In order to improve the problem that the viscosity of the foundation liquid is too high and not easy to spread evenly, the present application provides a lyophilized foundation liquid and a preparation method thereof.

[0006] The present application provides a lyophilized foundation liquid, which adopts the following technical scheme: A lyophilized foundation liquid, comprising A component and B component, characterized in that the A component comprises: potassium magnesium fluosilicate 2.2-2.8%, filler 7-9%, lauroyl lysine 0.8-1.2%, titanium dioxide 7.5-8.5%, CI 77492 0.2-0.4%, CI 774910.10-0.15%, CI 77499 0.01-0.02%, water balance, butanediol 9-11%, xanthan gum 0.02-0.08%, thickening agent 0.1-0.2%, trehalose 0.8-1.2%, polysorbate-60 0.3-0.7%, emulsifier a 1.2-1.7%, phenyl trimethicone 1.8-2.2%, isononyl isononanoate 1.7-2.3%, preservative 0.8-1.1%; In the B component: water balance, butanediol 8-12%, preservative 0.8-1.2%, magnesium sulfate 0.7-1.3%, emollient 10-14%, lithium montmorillonite 0.3-0.7%, phenyl trimethyl siloxane 1.8-2.3%, isododecane 4.7-5.3%, trimethyl siloxy silicate 2.8-3.2%, emulsifier b 2.2-2.8%, PEG-10 dimethicone 1.3-1.7%.

[0007] By adopting the above technical scheme, potassium magnesium fluosilicate is used as a skin feel regulator, high-refraction soft-focus powder, which improves the smoothness and spreadability of the foundation, reduces the frictional feeling during application, makes the foundation easier to push, and improves the uniformity of the pores after freeze-drying. The filler provides a soft-focus feeling, reduces stickiness, and lauroyl lysine has lubricating and dispersing effects, allowing the powder to adhere more evenly to the skin surface and improving the skin feel. Titanium dioxide physically covers up, brightens the skin color, and hides uneven skin color and imperfections by scattering light, improving the whiteness and concealing power of the foundation.

[0008] CI 77492 / CI 77491 / CI 77499 toning pigments (toning iron yellow, iron red, iron black) are used to match the natural color tone of different skin colors and match the skin undertone. Butanediol as a small molecule humectant can absorb environmental moisture and lock in skin moisture, while enhancing the solubility of other ingredients. Xanthan gum and thickening agent adjust the viscosity of the system, prevent stratification of ingredients, and make the texture more stable. Trehalose as a freeze-drying protective agent can form a protective film on the skin surface, reducing water loss. Polysorbate-60 and emulsifier a help mix the water and oil phases to form a stable emulsion. Phenyl trimethyl siloxane and isononyl isononanoate as silicone and fatty acid ester oils, synergistically cooperate to improve the smoothness of the foundation, moisturize the skin, reduce the dry feeling during application, and make the makeup more comfortable.

[0009] In the B component, water and butanediol are used as moisturizing and dispersing solvents to provide a solubilizing environment and basic moisturization. Preservative preservative synergist, supplementing the preservative efficacy of phase A, magnesium sulfate as an electrolyte stabilizer, enhancing the polar head binding force of emulsifier b, preventing freeze-thaw demulsification, and synergizing with lithium montmorillonite to adjust the viscosity of the system, enhance the stability of the emulsion, and prevent oil and water stratification. Emollients enhance skin moisturization, prevent powder from sticking to dry skin, lithium montmorillonite organic clay thickening, impart thixotropy, and prevent powder sedimentation. Phenyl trimethyl siloxane as a high-adhesion silicone oil improves the makeup retention and skin feel of the foundation.

[0010] Isododecane spreads quickly and evaporates rapidly, promoting quick film formation and leaving a clean skin feel, reducing the greasy feeling. Trimethylsiloxysilicate can form a thin film on the surface of the skin, improving the hold and transfer resistance of the foundation (reducing makeup transfer). Emulsifier b enhances water-oil compatibility, PEG-10 dimethicone is a hydrophilic silicone that can balance the smoothness and moisturizing properties of silicone components, improving compatibility with the skin.

[0011] The A and B components are stored separately and mixed when used, which can reduce the interaction between the components and improve product stability and freshness. Silicone components give the foundation a smooth and clean skin feel, avoiding heavy and sticky feeling; lauroyl lysine and the like enhance powder dispersibility and reduce powder sticking. By compounding thickening agents (xanthan gum, montmorillonite), emulsifiers (polysorbate-60, emulsifiers a / b) and magnesium sulfate, it is ensured that the A and B components form a stable emulsion after mixing, which is not prone to stratification or deterioration.

[0012] Preferably, in the A component, by weight percentage: potassium magnesium fluorosilicate 2.5%, filler 8%, lauroyl lysine 1%, titanium dioxide 8%, CI 77492 0.3%, CI 77491 0.13%, CI 77499 0.01%, water 61.91%, butanediol 10%, xanthan gum 0.05%, thickening agent 0.1%, trehalose 1%, polysorbate-60 0.5%, emulsifier a 1.5%, phenyl trimethicone 2%, isononyl isononanoate 2%, preservative 1%; In the B component: water 61.5%, butanediol 10%, preservative 1%, magnesium sulfate 1%, emollient 12%, lithium montmorillonite dimethicone 0.5%, phenyl trimethicone 2%, isododecane 5%, trimethylsiloxysilicate 3%, emulsifier b 2.5%, PEG-10 dimethicone 1.5%.

[0013] By using the above technical scheme, the values of each component of the A component and the B component are further limited. The components cooperate with each other at these values, and the freeze-dried foundation liquid obtained has excellent moisturizing properties. Multiple components synergistically cooperate to improve the uniformity of the foundation, so that the foundation has good viscosity, which helps to adhere to the skin, keep the skin moist, and prolong the makeup holding property and skin feel of the foundation.

[0014] Preferably, in the A component: the filler is HDI / PPG / polycaprolactone cross-linked polymer and silica, and the amount ratio of HDI / PPG / polycaprolactone cross-linked polymer and silica is 5-6:1.

[0015] By adopting the technical scheme, the HDI / PPG / polycaprolactone cross-linked polymer is spherical microparticles, has smooth surface and certain elasticity, can reduce the friction between the powder and the skin when being applied, makes the product more easily pushed, and avoids the dry feeling of traditional powder. Moreover, the particle size of the HDI / PPG / polycaprolactone cross-linked polymer matches the skin texture (such as fine lines and pores), can physically fill the concave and convex parts, visually fade the fine lines and hide the pores, and plays the role of instant smoothing makeup effect modification. The silica has a porous structure, has oil absorption and moisture absorption, and can quickly absorb the excess oil and sweat on the surface of the skin. The surface of the silica is inert and has anti-aggregation effect, can uniformly disperse other powders in the formula, prevents the aggregation of particles to form lumps, and ensures that the product has delicate texture and no particle feeling.

[0016] The HDI / PPG / polycaprolactone cross-linked polymer and the silica are synergistically compounded, the HDI / PPG / polycaprolactone cross-linked polymer provides a flexible and elastic film as a basic filling layer, is attached to the dynamic changes of the skin, and the silica provides hard and solid microparticles for instant and deep physical filling. The two realize instant and long-lasting filling and soft focus effect, can fill the static texture, and can also adapt to the dynamic changes of the face without cracking. Moreover, the HDI / PPG / polycaprolactone cross-linked polymer is a waterproof, sweat-resistant and anti-friction basic barrier, the silica absorbs oil and controls oil, reduces the off makeup and dissolved makeup caused by oil secretion. The two jointly act, significantly improve the long-lastingness and environmental factor resistance of the product.

[0017] Preferably, in the A component: the thickening agent is hydroxyethyl cellulose, disodium hydrogen phosphate, sodium dihydrogen phosphate and polysorbate-60, and the amount ratio is 980-995:4.5-5.5:1:4.5-5.5.

[0018] By adopting the technical scheme, the hydroxyethyl cellulose provides basic viscosity and rheological property, the molecular chain is fully stretched in water to form a three-dimensional network structure, wraps water molecules and other components, and significantly improves the consistency of the system. The disodium hydrogen phosphate and the sodium dihydrogen phosphate stabilize the pH value of the system, the thickening ability of the hydroxyethyl cellulose is sensitive to pH, the buffer effect of the disodium hydrogen phosphate and the sodium dihydrogen phosphate quickly adjusts the + / OH- concentration, locks the pH in the best thickening interval of the hydroxyethyl cellulose, and ensures the stability of the thickening effect. The polysorbate-60 is an emulsifying dispersant, reduces the surface tension of water, helps the hydroxyethyl cellulose particles to quickly wet and disperse, avoids clumping, and ensures uniform thickening.

[0019] The components cooperate synergistically, the phosphate buffer stabilizes the pH, ensures that the hydroxyethyl cellulose molecular chain is fully stretched, maintains the best thickening efficiency, the polysorbate-60 reduces the surface tension, promotes the rapid dissolution of hydroxyethyl cellulose, avoids local viscosity unevenness, the polysorbate-60 emulsifies the oil phase, the hydroxyethyl cellulose reticular structure fixes the liquid droplets, the phosphate stabilizes the pH to avoid emulsion demulsification, the lubricity of the polysorbate-60 neutralizes the dryness of the hydroxyethyl cellulose, the pseudoplastic rheological property of the hydroxyethyl cellulose ensures that the system is thick but not sticky, and finally realizes the effects of fine texture, easy to apply, no layering, and stable storage.

[0020] Preferably, in the A component: the emulsifier a is PEG-100 stearate, glyceryl stearate, and the dosage ratio is 0.8-1.2:1; The preservative is phenoxyethanol and caprylyl glycol, and the dosage ratio is 1.8-1.9:1.

[0021] By adopting the above technical scheme, PEG-100 stearate belongs to a hydrophilic emulsifier, has strong emulsifying capacity, enhances the affinity of the emulsion and the water phase, glyceryl stearate belongs to an oleophilic emulsifier, reduces the oil-water interfacial tension, and can increase the system thickness in the emulsion.

[0022] PEG-100 stearate and glyceryl stearate cooperate to achieve complementation, glyceryl stearate is suitable for a high oil phase but lacks hydrophilicity; PEG-100 stearate is suitable for a high water phase but lacks oleophilicity. After the two are compounded, the oil droplets are uniformly dispersed and stable for a long time.

[0023] The oleophilic end of glyceryl stearate anchors the oil phase to form a rigid skeleton, the hydrophilic end of PEG-100 stearate penetrates into the water phase to provide flexible extension, and the two interweave at the oil-water interface to form a more dense and stronger composite interface film, which brings a refreshing skin feeling with fine texture and smooth application.

[0024] Phenoxyethanol has strong stability, broad-spectrum antibacterial property, and weak fungal inhibition capacity, caprylyl glycol assists in antibacterial property, enhances fungal inhibition, and has moisturizing and thickening effects. The mixture of the two complements the antibacterial spectrum, covers more microorganisms, synergistically enhances the antibacterial efficiency, improves the system stability, and prolongs the shelf life.

[0025] Preferably, in the B component: the emollient is cyclohexasiloxane and cyclopentasiloxane, and the dosage ratio is 1:1.82-1.88.

[0026] The emulsifier b is lauryl PEG-9 polydimethylsiloxyethyl dimethicone and tocopherol (vitamin E).

[0027] By adopting the above technical scheme, the viscosity of cyclopentasiloxane is low, the fluidity is good, the texture is light, and the compatibility with oil and active ingredients (such as vitamins) is good; the viscosity of cyclohexasiloxane is lower than that of cyclopentasiloxane, and the volatility is stronger, which can quickly take away the sticky feeling on the surface of the skin, and the fluidity is excellent, which can help other components (such as powder and oil) to be more evenly distributed on the surface of the skin, avoiding local accumulation.

[0028] The two are mixed and the skin feels complementary, the evaporation speed of cyclopentasiloxane is moderate, the residual silicone film can provide continuous smoothness, and avoid skin tightness due to excessive evaporation; cyclohexasiloxane has stronger volatility, which can quickly disperse the slight residual feeling of cyclopentasiloxane, reduce the problem of "excessive silicon feeling", reduce stickiness, improve powder spreadability, and make the makeup more natural.

[0029] Preferably, the B component further comprises a microcapsule, and the wall material of the microcapsule is soybean protein, sea buckthorn seed oil, ceramide, and dioctyl carbonate, and the core material is oat peptide, daisy extract, betaine, and hydroxypropyl methyl cellulose.

[0030] By adopting the above technical scheme, in the wall material, the soybean protein molecule contains polar groups such as amino and carboxyl groups, which can form a dense film at the oil-water interface through hydrogen bonding and hydrophobic interaction, serving as the skeleton of the microcapsule to prevent leakage of the core material. Sea buckthorn seed oil is rich in unsaturated fatty acids, which can improve the flexibility of the capsule wall and prevent dryness and brittle fracture. Dioctyl carbonate is a light oil that reduces the hydrophilicity of the wall material, preventing the core material (such as oat peptide and betaine) from dissolving prematurely when exposed to water, thereby extending the storage stability. Ceramide is embedded in the membrane structure formed by soybean protein, enhancing the compatibility of the wall material with the stratum corneum of the skin and having the functions of moisturizing and repairing the skin barrier.

[0031] In the core material, oat peptide can penetrate the surface layer of the skin, promote the synthesis of moisturizing factors in the stratum corneum, alleviate dryness-induced makeup removal, and has a soothing effect to reduce the irritation of powder to the skin. Daisy extract contains flavonoids, polyphenols and other antioxidant ingredients, which can scavenge free radicals and inhibit oxidative damage to the skin caused by external stimuli, thereby assisting in maintaining the durability of the makeup (reducing dullness). Betaine absorbs environmental moisture through osmotic pressure balance and forms a moisturizing film on the surface of the skin, preventing the accumulation of powder and unevenness caused by dry skin. Hydroxypropyl methyl cellulose acts as a dispersion stabilizer for the core material, preventing oat peptide and extract from settling due to density differences, and increasing the viscosity of the core material solution, which facilitates the encapsulation of the wall material.

[0032] The obtained microcapsules, in use, the wall material gradually swells or breaks, the core material is slowly released, oat peptide, betaine instant moisturizing (avoid dry when makeup), daisy extract continuous antioxidant (reduce makeup dull). The ceramide in the wall material is homologous with the skin lipid, which can reduce the friction feeling of the microcapsules and the skin, make the makeup smoother, the slow release of the core material avoids the one-time contact of high-concentration active ingredients with the skin, reduces the skin feeling burden, and achieves the effects of long-acting skin care and optimized skin feeling.

[0033] Preferably, the mass ratio of the daisy extract, betaine and hydroxypropyl methyl cellulose is 1:0.5-0.6:0.1-0.2.

[0034] By adopting the above technical solution, the mass ratio of the daisy extract, betaine and hydroxypropyl methyl cellulose is further limited within a certain range, and the obtained core material has excellent comprehensive effect. The daisy extract has anti-inflammatory and soothing effect, which can reduce the redness and discomfort of the skin caused by barrier fragility or external stimulation; the betaine maintains the moisturizing state of the skin to enhance the barrier tolerance; the daisy extract and the betaine are complementary in moisturizing and anti-inflammatory, the daisy extract specifically improves the inflammatory reaction, and the overall repair effect is improved. The hydroxypropyl methyl cellulose forms a high-viscosity three-dimensional hydrophilic colloid network after dissolution, which wraps and protects the activity of the daisy extract and the betaine, so that the daisy extract and the betaine are combined closely, the degradation of the two before storage or use is reduced, the stability of the active ingredients is indirectly ensured, and the moisturizing and soothing effects are more durable.

[0035] In a second aspect, the application also provides a preparation method of the freeze-dried foundation liquid, comprising the following steps: A component preparation method: (1) Powder preparation: uniformly stir potassium magnesium fluosilicate, filler, lauroyl lysine, titanium dioxide, CI 77492, CI 77491 and CI 77499 in a powder mixing pot to obtain a mixture A; (2) Emulsion preparation: mix water, butylene glycol, xanthan gum, thickening agent and trehalose in an emulsifying pot and heat to 80-85 DEG C to obtain a mixture B; (3) Emulsion preparation: mix water, butylene glycol, xanthan gum, thickening agent and trehalose in an emulsifying pot and heat to 80-85 DEG C to obtain a mixture B; (3) Add the mixture A to the mixture C and stir to obtain a mixture D; (4) Freeze the mixture D in a-40 DEG C freezer, and then freeze in a freeze-drying equipment for 24 h until the water content of the powder is less than or equal to 3%, and obtain a freeze-dried powder ball; B component preparation method: (1) In the emulsifying pot, the water balance, butanediol, preservative, magnesium sulfate, emollient are mixed and heated to 80-85℃ to obtain mixture E; (2) The lithium montmorillonite of distearyl dimethyl ammonium, phenyl trimethyl siloxane, isododecane, trimethyl siloxy silicate, emulsifier b, PEG-10 dimethicone are heated and stirred uniformly in the oil pot at 60-65℃ to obtain mixture F; Mixture F is slowly added to the emulsifying pot under stirring conditions to obtain mixture G.

[0036] By adopting the above technical scheme, the powder phase is prepared to obtain uniformly dispersed powder, avoiding agglomeration, ensuring uniform particle size of the powder, and improving efficiency. The emulsion is prepared to obtain uniform and stable emulsion, ensuring that the emulsion does not separate.

[0037] Controlling the temperature of the water phase / oil phase and the stirring speed ensures uniform oil droplet particle size of the emulsion. When mixed with the powder phase later, the powder can be uniformly adsorbed on the surface of the oil droplets or dispersed in the water phase, and a powder ball with consistent structure is formed after freeze-drying.

[0038] Preferably, when in use, mixture G of component B is poured onto the freeze-dried powder ball of component A (B:A mass ratio is 5-6:1), and the freeze-dried powder ball is emulsified with mixture G to form a uniform emulsion, which can be used.

[0039] By adopting the above technical scheme, the reasonable proportion of component A and component B is set to form a fine emulsion, ensuring that there are no obvious powder particles and the texture is smooth, avoiding excessive moisturizing leading to oiliness.

[0040] In summary, the present application has the following beneficial effects: 1. The filler in the present application provides a soft focus effect and reduces stickiness. Lauroyl lysine has lubricating and dispersing effects, which can make the powder more uniformly adhere to the skin surface and improve the skin feel.

[0041] 2. The phenyl trimethyl siloxane and isononyl isononanoate in the present application are used as siloxane and fatty acid ester oils, which cooperate with each other to improve the smoothness of the foundation, moisturize the skin, reduce the dry feeling during application, and make the makeup effect more comfortable.

[0042] 3. The enhanced emulsifier b in the present application has a strong polar head bonding force, which prevents freeze-thaw demulsification. In addition, it cooperates with lithium montmorillonite of distearyl dimethyl ammonium to adjust the viscosity of the system and enhance the stability of the emulsion, preventing oil and water from separating.

[0091] Comparative Example 5 A lyophilized foundation liquid, which is different from Example 1 in that no emulsifier b is added.

[0092] Performance test test The lyophilized foundation liquids prepared by Examples 1-12 and Comparative Examples 1-5 are subjected to performance tests; Skin moisture content test: the skin moisture content at week 0 is set as MMV0, the skin moisture content at week 4 is set as MMV4, the skin moisture content change value is ΔMMV, ΔMMV = MMV4-MMV0.

[0093] Test instrument: Cutometer@ dual MPA 580 of Germany CK, the probes used for testing include: Corneometer CM825 (moisture test probe), Cutometer MPA 580 (skin elasticity test probe).

[0094] Skin elasticity test: the skin elasticity value at week 0 is set as ΔA0, the skin elasticity value at week 4 is set as ΔA4, the skin elasticity change value is ΔA, ΔA = ΔA4-ΔA0; Anti-migration performance: 0.40 g of foundation liquid (total amount) was dropped on the skin of the human arm, respectively, and evenly spread, and then left to dry naturally for 6 min. Three regions were pressed with a paper towel at the same force, and the weight increment of the three paper towels (foundation migration amount) was weighed with an analytical balance, respectively. The migration rate = migration amount / total amount x 100%, and the test results are shown in Table 1.

[0095] Table 1 Test data of examples and comparative examples Skin feel and soft focus effect: select women with an average age of 25±5 years old, each of whom applies the foundation liquid to the arm, and evaluates the coverage, spreadability, oil control, and durability, and ranks the scores from best to worst (i.e. the best score is 5, and the next scores are 4, 3, 2, and 1, respectively). The scores of all the evaluators are added up to calculate the average value, and the test results are shown in Table 2.

[0096] Table 2 Test data of examples and comparative examples As can be seen from Table 1, the freeze-dried foundation liquid prepared in Examples 1-3 has good comprehensive performance, wherein the ΔMMV of Example 1 is 20.3658, the ΔA is 0.1356, and the migration rate is 6.75%. In addition, in the scoring results, the coverage of Example 1 is 4.12, the spreadability is 4.26, the oil control is 4.35, and the durability is 4.39. It can be seen that the freeze-dried foundation liquid prepared in the present application improves the smoothness and spreadability of the foundation, reduces the friction feeling during application, makes the foundation easier to push open, and the combination of various components provides hydration and moisturization, and makes the makeup effect more comfortable.

[0097] Examples 4-5 also include microcapsules. As can be seen from Table 1, the ΔMMV of Example 4 is 28.6547, the ΔA is 0.4536, and the migration rate is 0.98%. In addition, in the scoring results, the coverage of Example 1 is 4.71, the spreadability is 4.81, the oil control is 4.86, and the durability is 4.92. It shows that during use, the wall material of the microcapsule gradually swells or breaks, the core material is slowly released, the oat peptide and betaine provide instant moisturization, the daisy extract provides continuous antioxidant effect, achieves long-acting skin care, and optimizes the skin feel.

[0098] From Table 1, it can be seen that the scores of △MMV, △A, migration rate, as well as concealing power, extensibility, oil control power and persistence of Examples 6-7 are obviously poorer than those of Examples 4-5, but better than those of Examples 1-3, and the corresponding test effects of Example 8 are better than those of Examples 6-7, but poorer than those of Examples 4-5, indicating that the chrysanthemum extract and betaine form a complement in moisturizing and anti-inflammatory, the chrysanthemum extract improves the overall repair effect, the hydroxypropyl methyl cellulose forms a three-dimensional hydrophilic colloid network with high viscosity after dissolution, which wraps and protects the activity of the chrysanthemum extract and betaine, so that the chrysanthemum extract and betaine are combined closely, indirectly ensuring the stability of the active ingredients, and making the moisturizing and soothing effects more persistent.

[0099] Examples 9-10 change the mass ratio of chrysanthemum, mesoporous silica nanospheres and silk fibroin nanofibers, and Examples 11-12 do not add mesoporous silica nanospheres and silk fibroin nanofibers respectively in the preparation method of chrysanthemum extract. From Table 1, it can be seen that the scores of △MMV, △A, migration rate, as well as concealing power, extensibility, oil control power and persistence of Examples 11-12 are obviously poorer than those of Examples 4-5, but better than those of Examples 1-3, and the corresponding test effects of Example 10 are better than those of Examples 11-12, but poorer than those of Examples 4-5, indicating that the mesoporous silica nanospheres load the chrysanthemum extract with a porous structure, the slow-release effect prolongs the antioxidant and soothing effect of chrysanthemum, and the mesoporous silica nanospheres not only have oil control and adsorption regulation, but also have skin feel optimization effect; the silk fibroin nanofibers are adsorbed on the surface of the mesoporous silica nanospheres, have long-acting moisturizing and water-locking effects, and improve the skin feel and texture, and repair the skin barrier.

[0100] From Table 1, it can be seen that the scores of △MMV, △A, migration rate, as well as concealing power, extensibility, oil control power and persistence of Comparative Examples 1-5 are obviously poorer than those of Examples 1-3, indicating that the fillers provide a soft focus effect and reduce stickiness, the thickening agent adjusts the viscosity of the system, prevents ingredients from stratifying, makes the texture more stable, the emulsifier a helps the water phase and the oil phase to mix, forms a stable emulsion, the emollient enhances the moisturizing degree of the skin, avoids the powdering of the foundation due to dry skin, and the emulsifier b enhances the compatibility of the water and oil phases, and improves the compatibility with the skin.
