The original application claimed priority as follows: CN2022112171867, filed on October 1, 2022. Technical Field

[0002] This invention relates to a water-in-oil emulsion, its preparation method, its application, its film, and cosmetic products containing it. Background Technology

[0003] Colored cosmetics refer to cosmetics containing a certain amount of pigments or other similar powders, applied to the skin, lips, and other human body surfaces by methods such as rubbing or spraying, to provide a certain degree of skin blemish correction or physical sun protection. These cosmetics do not have particularly limited product textures, including wax-based, oil-gel, and cream types. Their skin-correcting and sun-protective functions are closely related to the dispersibility of the pigments and require the pigments to remain on the skin surface for a certain period of time. Therefore, film-forming properties are one of the key factors affecting the performance of colored cosmetics.

[0004] Film-forming agents in cosmetics refer to the formation of a continuous and uniform thin film on the skin surface, possessing certain softness, extensibility, abrasion resistance, and water resistance. When applied to cosmetics, film-forming agents can improve the product's water and sweat resistance, increase its oil control, control its spreadability and rheology, thereby improving ease of application, enhancing the uniformity of film formation during application, allowing cosmetic powders to spread more evenly, and maintaining the film thickness on the skin for a longer period. Studies have shown that film-forming agents can improve the film-forming ability and water resistance of cosmetics during application, thus improving the makeup's staying power.

[0005] In cosmetics, film-forming agents refer to the formation of a continuous, uniform thin film on the skin surface, possessing certain softness, extensibility, abrasion resistance, and water resistance. When film-forming agents are applied to tinted makeup products that correct facial imperfections, they can alter the rheological properties of the product during application, increasing its stability. This not only improves the product's water and sweat resistance, oil control, and spreadability and rheology, thus enhancing ease of application, but also improves the uniformity of film formation during makeup application, allowing the makeup powder to spread more evenly and maintain a longer-lasting film thickness on the skin. Studies have shown that film-forming agents can improve the film-forming ability and water resistance of makeup during application, thereby enhancing its staying power.

[0006] Traditional film-forming agents used in cosmetics are mainly silicone resins, polyacrylates, and polyurethanes, which are high molecular weight polymers obtained by the repeated polymerization of monomers. These polymer molecules have repeating units and are large molecules. When dispersed and diluted in volatile solvents, the gaps between polymer molecules are relatively large, and the intermolecular forces are weak. Individual molecules curl up and occupy a small space. After the solvent evaporates, the gaps between polymer molecules shrink, the intermolecular forces strengthen, and the polymer molecules begin to overlap, align, and entangle, ultimately forming a three-dimensional network structure that forms a thin film on the skin surface. This type of polymer film has a certain degree of hardness and brittleness; therefore, it is prone to breakage when excessively dried.

[0007] Wax is a general term for hydrophobic substances with varying degrees of luster, smoothness, and plasticity. It can also be considered a substance containing specific organic thermoplastic groups, with melting points ranging from 35-95℃. Based on their origin, they can be classified into plant waxes, animal waxes, mineral-based natural waxes, and chemically synthesized waxes. They can form a continuous hydrophobic film on the skin, and compared to traditional polymers, they belong to the small-molecule film-forming agent category. However, wax-formed films exhibit high continuity, low porosity, and low oxygen permeability, resulting in a sticky feel and poor breathability when forming a film on the skin.

[0008] Studies have shown that the orderly arrangement of rod-shaped amphiphilic molecules in liquid crystals, along with their birefringence of light, creates unique visual effects in colored cosmetics. Thermotropic liquid crystals, in particular, exhibit vibrant colors that change with temperature in color-enhancing cosmetics. Furthermore, the formation of the liquid crystal structure reduces van der Waals forces between dispersed droplets, thereby reducing droplet aggregation and making the emulsion system more stable. The lamellar liquid crystal structure is also similar to the lipid layer structure of the stratum corneum of real skin. When applied to the skin, lamellar liquid crystals exhibit better affinity and improve skin hydration while reducing transepidermal water loss. Therefore, thermotropic liquid crystals show promise in the cosmetic field, but the application of their unique lamellar films in film-forming systems has not yet been explored.

[0009] Sterols and their derivatives are thermotropic liquid crystal substances. For example, phytosterols, also known as plant sterols, belong to the plant steroidal compounds. The main components of phytosterols include sitosterol, brassosterol, stigmasterol, rapeseed sterol, and corresponding alkanols, all with a cyclopentane-perhydrophenanthrene backbone structure. Phytosterol derivatives, also known as phytosterol esters, are obtained by esterification of phytosterols with higher fatty acids. They retain the physiological activity of phytosterols and have a wider range of applications.

[0010] However, the liquid crystal phase behavior of sterols and their derivatives is greatly affected by temperature. When the external temperature is lower than the melting point temperature (Tcn, where c represents crystal) of the sterol derivatives, the sterol derivatives will spontaneously crystallize in the water-in-oil system, aggregate and precipitate from the system, affecting the uniformity of the system and the texture of the product.

[0011] Therefore, how to effectively apply sterols and their derivatives to water-in-oil systems to improve the film-forming properties of cosmetics is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0012] To address the aforementioned technical problems, this invention provides a water-in-oil emulsion, its preparation method, applications, films, and cosmetic products containing the same. The water-in-oil emulsion of this invention can form a liquid crystal structure arranged in a spatially ordered manner according to a certain direction. It exhibits low film continuity, hydrophobicity, the flexibility of a wax film, excellent breathability, and some migration resistance of a polymer film while improving brittleness. Furthermore, it can also improve the brittleness of a uniform and continuous three-dimensional network film formed on the skin, enhancing flexibility and uniformity.

[0013] Compared with traditional polymer film-forming agents, this invention uses sterols and their derivatives (such as phytosterols and their derivatives, cholesterol and their derivatives) as film-forming agents, utilizing the orderly arrangement of small molecules to form consistent stability (or crystallization), thus effectively solving the brittleness problem that polymer film-forming agents bring when improving the consistent stability of the film.

[0014] Compared with traditional wax film formation, sterols and their derivatives (such as phytosterols and their derivatives, cholesterol and their derivatives) have a similar molecular size to wax, but their structure is more irregular. Therefore, the molecular arrangement is less continuous after film formation, resulting in higher porosity and oxygen permeability, which improves the stickiness and impermeability problems caused by the high continuity of wax films.

[0015] During the research and development process, the inventors discovered that traditional film-forming agents form a three-dimensional network structure on the skin surface by intertwining large polymer molecules. In contrast, sterols and their derivatives (such as phytosterols and their derivatives, cholesterol and their derivatives), due to their molecular structure characteristics, aggregate to form films, arranged in an orderly manner in a certain direction in space (liquid crystal). This results in low film continuity, hydrophobicity, and the flexibility of wax films, but with improved continuity (better breathability). It also possesses some migration resistance of polymer films but with reduced brittleness, making it more environmentally friendly than film-forming agents based on plastic polymers.

[0016] During the research and development process, the inventors also discovered that the solid-state crystallization phenomenon under low-temperature conditions is a challenge for the application of sterols and their derivatives (such as phytosterols and their derivatives, cholesterol and their derivatives) in water-in-oil systems. Based on this, the present invention employs the following technical solution to address this technical problem.

[0161] Effect Example

[0162] The emulsions prepared using the formulations in the above examples and comparative examples were subjected to the following index measurements.

[0163] (1) Evenness of application

[0164] Twenty Asian women aged 20-50 years were included as participants.

[0165] The subject's left forearm and palm were placed flat on a table. Using the pad of the right middle finger, 0.5g of each of the examples and comparative examples of water-in-oil emulsion cosmetics were applied to the skin of the inside of the left wrist along the ulna, and then spread horizontally once. The fingerprints from the applied water-in-oil emulsion cosmetics were visually evaluated.

[0166] Twenty participants underwent sensory evaluations across the following five phases.

[0167] 5: The surface looks very uniform.

[0168] 4: The surface appears to be basically uniform.

[0169] 3: The surface appears relatively uniform.

[0170] 2: The surface appears slightly uneven.

[0171] 1: The surface appears uneven.

[0172] The specific data of the water-in-oil emulsions prepared in Examples 5, 6, 7, 10, and 15 are shown in Table 11.

[0173] Table 11

[0174] As shown in Table 11, the water-in-oil emulsions prepared in Examples 5, 6, 7, 10, and 15 can at least ensure that they appear basically uniform on the skin surface.

[0175] Based on the above experimental scoring example, the results, expressed as the average assessment scores of 20 subjects over 8 hours, are shown in Table 12 below.

[0176] Table 12

[0177] Based on the table above, we can see that: ① The oil-in-water emulsion of the present invention has good uniformity when applied to the skin, and can achieve at least 2 points (the surface appears slightly uneven).

[0178] ② For formulations containing sterols and / or sterol derivatives but without polymers, the application uniformity is generally good; however, with the increase in the amount of sterols and / or sterol derivatives, the application uniformity does not change significantly or decreases slightly.

[0179] ③ For formulations containing sterols and / or sterol derivatives and polymers, the application uniformity is generally good. With the increase of polymer content, the application uniformity does not change significantly or decreases slightly.

[0180] ④ For formulations that do not contain sterols and / or sterol derivatives but contain polymers, the uniformity of application gradually decreases as the amount of polymer increases.

[0181] (2) Migration resistance

[0182] Index definition: The ability of a film to maintain uniformity and adhesion under certain pressure (directly determined by adhesion).

[0183] Testing Methods: Twenty Asian women aged 20-50 years were selected as subjects. The formulations used in the examples and comparative studies were employed for evaluation.

[0184] Subjects did not apply any cosmetic products. After cleansing their faces with water, they applied makeup with their fingers, using 0.16ml for the entire face.

[0185] In a normal room temperature environment, subjects were subjected to a pressing test on their faces, which were coated with water-in-oil emulsion cosmetics, every 2 hours.

[0186] The pressing method is as follows: After covering your face with a plain tissue in both hands, gently press once on each cheek, nose, and forehead area.

[0187] The assessment method involved subjects observing the pressed tissue and conducting sensory evaluations based on the following five stages.

[0188] 5: Does not get stained or hardly gets stained with color.

[0189] 4: Slightly stained with color.

[0190] 3: Some parts are stained with color.

[0191] 2: It is stained with a lot of color.

[0192] 1: It is stained with a great many colors.

[0193] The specific detection data for Example 2B are shown in Table 13.

[0194] Table 13

[0195] As shown in Table 4, the water-in-oil emulsion prepared in Example 2B exhibits excellent migration resistance.

[0196] Based on the above experimental scoring example, the results, expressed as the average assessment scores of 20 subjects at the above three sites within 8 hours, are shown in Table 14 below.

[0197] Table 14

[0198] Based on the table above, we can see that: ① The oil-in-water emulsion of this invention has good evenness when applied to the skin, and can achieve at least 2 points (more color transfer).

[0199] ② For formulations containing sterols and / or sterol derivatives but without polymers, their anti-migration ability is excellent; as the amount of sterols and / or sterol derivatives increases, the uniformity of application does not change significantly or decreases slightly; the formulations in this invention can still maintain a high level of anti-migration ability when the content of sterols and / or sterol derivatives is high (e.g., 39.5%), while at the same amount, the anti-migration ability of formulations without sterols and / or sterol derivatives but containing polymers decreases to a lower level.

[0200] ③ For formulations containing sterols and / or sterol derivatives and polymers, their anti-migration ability is good. With the increase of polymer content, their anti-migration ability does not change significantly or decreases slightly.

[0201] ④ For formulations that do not contain sterols and / or sterol derivatives but contain polymers, their anti-migration ability gradually decreases as the amount of polymer increases.

[0202] (3) Membrane durability

[0203] Indicator definition: The ability of a film to maintain uniformity and adhesion over a long period of time, and to still meet the definition of a film over a long period of time; here, the definition of a film means that after a period of time, it still has the characteristics of abrasion resistance, water resistance, and oil control.

[0204] Experimental Methods: Twenty Asian women aged 20-50 years were selected as subjects. Using the formulations of the examples and comparative examples, matte lipstick and eyeliner were applied side-by-side along the ulna direction to the skin on the inside of the subjects' left wrists, forming two colored bands, each with an area of ​​1cm × 10cm.

[0205] Use your fingertips to apply the oil-in-water emulsion cosmetic evenly in horizontal sections, covering both color bands.

[0206] After the first layer of cosmetic has been applied to the color band and formed a stable film, gently wipe it off with your index fingertip.

[0207] Twenty participants underwent sensory evaluations across the following five phases.

[0208] 5 points: The color is not damaged.

[0209] 4 points: The color is slightly damaged.

[0210] 3 points: Few colors or damage.

[0211] 2 points: Many colors are damaged.

[0212] 1 point: The color is basically damaged.

[0213] The specific data of the water-in-oil emulsions prepared in Examples 5, 6, 7, 10, and 15 are shown in Table 15.

[0214] Table 15

[0215] As shown in Table 15, the water-in-oil emulsions prepared in Examples 5, 6, 7, 10, and 15 exhibit excellent stability after film formation.

[0216] Based on the above experimental scoring example, the results, expressed as the average evaluation scores of 20 subjects, are shown in Table 16 below.

[0217] Table 16

[0218] Based on the table above, we can see that: ①The water-in-oil emulsion of the present invention forms a film on the skin with good durability, which can reach at least 2 points.

[0219] ② For formulations containing sterols and / or sterol derivatives but without polymers, the resulting films exhibit good durability, and the amount of sterols and / or sterol derivatives has little effect on the durability of the films.

[0220] ③ For formulations containing sterols and / or sterol derivatives and polymers, the film formed has better durability. However, the durability of the film decreases slightly with the increase of polymer content.

[0221] ④ For formulations that do not contain sterols and / or sterol derivatives but contain polymers, the durability of the film formed is relatively poor compared to formulations containing sterols and / or sterol derivatives. As the amount of polymer increases, the durability of the film formed tends to decrease.

[0222] (4) Uniform peeling

[0223] After each group of samples was coated onto artificial leather to form a film, the roughness difference before and after 30 folds was measured. At the same time, the peeling weight was measured after the tape was applied to evaluate the product's conformability.

[0224] Experimental methods: 1. Apply the sample to artificial leather using a 25 μm four-sided coater and dry it for 60 min under constant temperature and humidity (temperature: 21±1 ℃; humidity: 50±5%) to form a film; 2. The roughness R2 of the sample after film formation was determined using the Visioscan® VC98 (Courage & Khazaka, Germany, abbreviated as VC98) active skin surface analysis system; Instrument Principle: The instrument uses a built-in ring-shaped UVA light to irradiate the skin, eliminating the influence of surface reflections. A special built-in sensor chip receives the light reflected from the stratum corneum, obtaining a texture image of the skin surface. Internal processing software converts the acquired image into a grayscale image, displayed in 255 grayscale pixels (0 for black, 255 for white). Parameters characterizing the skin condition are derived based on the comparison of the grayscale value of each pixel. Darker colors represent wrinkles, lighter colors represent bumps, and white represents shed keratin. Image analysis software provides parameters evaluating the skin surface condition, including wrinkle depth, wrinkle area and volume, overall skin roughness, smoothness, and uniformity. R² is derived from Rm or Rmax: Within the measurement length, the contour line is divided into five equal segments. The vertical distance between the highest peak and the deepest trough on each segment is calculated, which is the difference between the largest and smallest grayscale values ​​on that segment. The maximum value among these five segments is the R² value.

[0225] 3. After folding the artificial leather coated with the sample 30 times (each fold should be made with uniform force and in the same direction, and the angle of each fold should be consistent), the roughness R2 of the sample after folding should be measured using VC98. 4. Cut 5cm lengths of 3M tape, weigh it, and use the 3M tape to adhere to a sample (this sample is applied to artificial leather and folded 30 times) at the creases with the same direction and force. (Effective adhesive area: 5cm long and 2.5cm wide). After peeling off the 3M tape, weigh it again and calculate the weight difference. Use a VC98 meter to measure the sample after tape application.

[0226] 5. In the above experimental method, each sample is tested twice in parallel to eliminate outlier data and obtain the average value.

[0227] Experimental evaluation criteria

[0228] 1) Use the weight of the folded and adhered material to control the fit; the less the better.

[0229] 2) The roughness uniformity of R2 after folding is used to characterize the degree of uniform peeling; the larger the value, the less uniform the peeling.

[0230] The conformability data are shown in Table 17: Table 17

[0231] Based on the table above, we can see that: ① The water-in-oil emulsions in this invention can form films well. After being applied to artificial leather and folded 30 times, the weight difference at the crease after being peeled off with 3M tape can be kept within 10%, or even up to 0.5%, which is significantly better than "formulations that do not contain sterols and / or sterol derivatives and contain polymers".

[0232] ② For formulations containing sterols and / or sterol derivatives but without polymers, the film-forming effect is excellent. As the amount of sterols and / or sterol derivatives increases, the peeling weight increases significantly. When the amount of sterols and / or sterol derivatives reaches 39.5%, the peeling weight remains at a low level. However, at the same amount, formulations that "do not contain sterols and / or sterol derivatives but contain polymers" have a peeling weight as high as 20%-100%. When the type of sterols and / or sterol derivatives is phytosterol macadamia oleate, the peeling weight is relatively lower.

[0233] ③ For formulations containing sterols and / or sterol derivatives and polymers, the film-forming effect is excellent. The polymer can partially replace sterols and / or sterol derivatives. The peeling weight is basically the same as that of "formulations containing sterols and / or sterol derivatives and without polymers". With the increase of polymer content, the peeling weight increases slightly.

[0234] The data on uniform peeling are shown in Table 18: Table 18

[0235] Based on the table above, we can see that: ① The oil-in-water emulsions in this invention can form films well. After being applied to artificial leather and forming a film, the difference in roughness R2 before and after 30 folds can be kept within 162%, or even up to 3.5%.

[0236] ② For formulations containing sterols and / or sterol derivatives but without polymers, the film-forming effect is excellent. As the amount of sterols and / or sterol derivatives increases, the roughness and uniformity of R2 deteriorates significantly. When the type of sterols and / or sterol derivatives is phytosterol macadamia oleate, the film-forming effect is relatively better.

[0237] ③ For formulations containing sterols and / or sterol derivatives and polymers, the film-forming effect is excellent. The polymer can partially replace sterols and / or sterol derivatives. The roughness and uniformity of R2 are basically equivalent to those of formulations containing sterols and / or sterol derivatives but without polymers. With the increase of polymer content, the roughness and uniformity of R2 deteriorates slightly. Under certain formulation conditions, such as "phytosterol macadamia oleate + trimethylsiloxysilicate" (10% by mass in the formulation, with a mass ratio of phytosterol macadamia oleate to trimethylsiloxysilicate of 5:5), the two produce a significant synergistic film-forming effect.

[0238] (5) Toughness

[0239] Experimental objective: To investigate the toughness of different emulsion film-forming materials.

[0240] Test method: (Sample application amount: 100μm four-sided applicator; fracture criterion: crack width ≥50μm)

[0241] a. Use A4 paper to place the four-sided coating tool at the same height as the elastic band (the elastic band length of all samples is the same). Apply the different test emulsions evenly to the elastic band using a 100μm four-sided coating tool. Place the samples coated on the elastic band in a 40℃ oven for 2 hours and then take them out for later use.

[0242] b. After drying, clamp the elastic band on a universal stretching machine, record the original length of the elastic band, and then test it with VC98.

[0243] c. Slowly stretch the elastic band. Stop stretching when both visual inspection and the VC98 probe confirm that cracks begin to appear in the elastic band. Record the stretching length at which cracks appear. Continue stretching after cracks appear, stretching the elastic band to 3 times its original length. Record the stretching length again and test with the VC98. Finally, remove the elastic band from the universal tensile testing machine. Test each sample twice in parallel to eliminate abnormal data and obtain the average value.

[0244] For samples that fractured before stretching, the following experimental steps were used: a. Use A4 paper to place the four-sided coater at the same height as the elastic band (the elastic band length of all samples should be consistent and the weight of the corresponding blank elastic band for each sample should be weighed). Apply the different test emulsions evenly to 100μm using the four-sided coater (for samples that are difficult to coat, add hand coating to record the coating amount and convert the coating amount into thickness, the thickness after conversion is 100μm). Place the coated elastic band in a 40℃ oven for 2 hours and then take it out for use.

[0245] b. After drying, weigh the elastic band and clamp it on a universal stretching machine. Take a picture with a VC98 and record the original length of the elastic band.

[0246] c. Slowly stretch the elastic band. Stop stretching when you can visually inspect and use the VC98 probe to confirm that there are obvious cracks in the elastic band. (A- For samples where only the edge of the elastic band is broken before stretching, stop stretching until the middle of the elastic band is also broken. B- For samples where both the edge and middle of the elastic band are broken before stretching, you can directly stretch the elastic band to 3 times its original length.) Then take a picture with the VC98 probe to confirm the state of the crack and record the stretching length when the crack appears.

[0247] d. Continue stretching after the initial crack appears, stretching the elastic band to 3 times its original length. Take a picture with a VC98 and record the stretched length. Then remove the elastic band from the universal tensile testing machine and weigh it. Test each sample twice in parallel to eliminate abnormal data and obtain the average value.

[0248] Experimental evaluation criteria: 1) The sample did not break before stretching: the elongation at break is used to characterize toughness, and the higher the elongation, the better the toughness.

[0249] Elongation at break = (Change in elastic length when the sample breaks / Original length of the elastic band) 100%

[0250] 2) Fracture before stretching: The toughness is characterized by the percentage of the residual weight of the sample after stretching by 3 times the elastic band relative to the original weight. The higher the percentage, the better the toughness.

[0251] Toughness = (Residual weight of sample after 3 times deformation and stretching / Original weight) 100%

[0252] Original weight = Elastic band application area x Application thickness x Density (each sample has its own density)

[0253] Original weight = Weight after applying elastic band - Weight before applying elastic band

[0254] The toughness data are shown in Table 19: Table 19

[0255] Note: In the above table The labeled examples and comparative examples show samples that fractured before stretching; none. The labeled examples and comparative examples show that the samples did not break before being stretched.

[0256] Based on the table above, we can see that: ① The water-in-oil emulsions in this invention can form films well, and the films formed have good toughness; for films that are not broken before stretching, their elongation at break can reach 52%; for films that are broken before stretching, the residual weight of the sample after stretching with an elastic band by 3 times the deformation can account for up to 90% of the original weight.

[0257] ② For formulations containing sterols and / or sterol derivatives but without polymers, the toughness of the resulting film is closely related to the type of sterols and / or sterol derivatives: when the sterols and / or sterol derivatives are selected from phytosterols or phytosterol / behenol / octyldodecyl lauroyl glutamate, the toughness of the resulting film gradually decreases with increasing amounts of sterols and / or sterol derivatives; when the sterols and / or sterol derivatives are selected from phytosterol macadamia oleate, the toughness of the resulting film first decreases and then increases with increasing amounts of sterols and / or sterol derivatives; when the type of sterols and / or sterol derivatives is phytosterol macadamia oleate, the toughness of the resulting film is relatively better.

[0258] ③ For formulations containing sterols and / or sterol derivatives and polymers, the resulting film has good toughness. The polymer can partially replace sterols or sterol derivatives. As the amount of polymer increases, the toughness of the resulting film tends to approach that of the polymer film.

[0259] ④ For formulations that do not contain sterols and / or sterol derivatives but contain polymers, the toughness of the resulting film gradually decreases as the amount of polymer increases; in particular, for the polymer trimethylsiloxysilicate, the resulting film breaks before stretching when its amount increases to more than 10%.

[0260] (6) Film formation

[0261] "Film formation" is defined as the formation of a uniform and continuous thin film after application.

[0262] Testing method: A panel of 20 cosmetic professionals applied the sample to their arms and visually inspected the dried film surface after 30 minutes to evaluate its continuity and uniformity and determine the film formation.

[0263] Scoring criteria: 1) All examples meet the criteria of excellent or good film formation; 2) Scoring is based on actual experience.

[0264] Experimental evaluation criteria: 3 points: Excellent film formation.

[0265] 2 points: Good film formation.

[0266] 1 point: Almost no film formation.

[0267] The results, expressed as the average score of the 20 professional review panel members, are shown in Table 20 below.

[0268] Table 20

[0269] Based on the table above, we can see that: ① The water-in-oil emulsion in this invention has good film-forming properties, and the film formed when applied to the arm has excellent continuity and uniformity.

[0270] ② For formulations containing sterols, the film-forming effect can be comparable to that of using only the polymer as a film-forming agent.

[0271] (7) Water resistant

[0272] Index definition: The ability of a thin film to maintain uniformity and adhesion after contact with water, which is positively correlated with the hydrophobicity of the thin film.

[0273] Experimental method: A panel of 20 cosmetic professionals applied the sample to their arms and allowed it to dry. Then, they kept it under running water for 30 seconds to observe the integrity of the film. They then rubbed the surface with their fingers and observed the integrity of the film again.

[0274] Scoring criteria: 5 points: The membrane showed no change in integrity under the action of water flow and finger friction, demonstrating excellent water resistance.

[0275] 4 points: Under the action of water flow, the integrity of the membrane remains unchanged. After being rubbed with a finger, the integrity of the membrane changes slightly, indicating good water resistance.

[0276] 3 points: Under the action of water flow, the integrity of the membrane changes slightly. After rubbing with a finger, the integrity of the membrane changes significantly, but it is acceptable and the water resistance is good.

[0277] 2 points: Under the action of water flow, the integrity of the membrane changes significantly, but it is acceptable. After rubbing with a finger, the integrity of the membrane changes more significantly, and the water resistance is slightly poor.

[0278] 1 point: Under the action of water flow, the integrity of the membrane changes significantly. When rubbed with a finger, the integrity of the membrane is almost destroyed, and its water resistance is very poor.

[0279] 0: Under the action of water flow, the membrane integrity is almost destroyed, and it has no water resistance.

[0280] The results, expressed as the average score of the 20 members of the professional review panel, are shown in Table 21 below.

[0281] Table 21

[0282] Based on the table above, we can see that: ① The water-in-oil emulsion in this invention forms a film with good water resistance on the skin, reaching at least 2 points (with slightly poor water resistance).

[0283] ② For formulations containing sterols and / or sterol derivatives but without polymers, the water resistance of the resulting films is generally good. However, the water resistance decreases slightly with the increase of the amount of sterols and / or sterol derivatives.

[0284] ③ For formulations containing sterols and / or sterol derivatives and polymers, the water resistance of the resulting films is generally good. However, as the amount of polymer increases, the water resistance of the resulting films decreases slightly.

[0285] ④ For formulations that do not contain sterols and / or sterol derivatives but contain polymers, the water resistance of the resulting film gradually decreases as the amount of polymer increases.

[0286] (8) Sweat resistant

[0287] The "sweat resistance" index is defined as the ability of a film to maintain uniformity and adhesion after contact with sweat, and is positively correlated with the hydrophobicity of the film.

[0288] Experimental method: Twenty members of the cosmetics professional review panel applied the lotion from the examples and comparative examples to their arms and allowed it to dry. Then, they used a misting bottle to spray artificial sweat onto the membrane, spraying 10 times continuously until the artificial sweat evenly covered the membrane surface. They pressed the membrane surface with a tissue, removed the sweat, and observed the integrity of the membrane. They rubbed the surface with their fingers and observed the integrity of the membrane again.

[0289] Sweat resistance rating: 5 points: After removing sweat and rubbing with fingers, the integrity of the membrane remained unchanged, demonstrating excellent sweat resistance.

[0290] 4 points: After removing sweat, the integrity of the membrane remained unchanged. After rubbing with a finger, the integrity of the membrane changed slightly, indicating good sweat resistance.

[0291] 3 points: After removing sweat, the integrity of the membrane changed slightly. After rubbing with fingers, the integrity of the membrane changed significantly, but it was acceptable. The sweat resistance was good.

[0292] 2 points: After removing sweat, the integrity of the membrane changed significantly, but it was acceptable. After rubbing with fingers, the integrity of the membrane changed more significantly, and its sweat resistance was slightly worse.

[0293] 1 point: After the sweat is removed, the integrity of the membrane changes significantly. When rubbed with a finger, the integrity of the membrane is almost destroyed, and its sweat resistance is very poor.

[0294] 0: After sweat is removed, the membrane integrity is almost completely destroyed, and it has no sweat resistance.

[0295] The results, expressed as the average score of the 20 members of the professional review panel, are shown in Table 22 below.

[0296] Table 22

[0297] Based on the table above, we can see that: ① The water-in-oil emulsion in this invention forms a film on the skin with good sweat resistance, which can reach at least 2 points (slightly poor sweat resistance).

[0298] ② For formulations containing sterols and / or sterol derivatives but without polymers, the resulting films exhibit good sweat resistance, and the sweat resistance does not change significantly with increasing amounts of sterols and / or sterol derivatives.

[0299] ③ For formulations containing sterols and / or sterol derivatives and polymers, the resulting films exhibit good sweat resistance. However, as the amount of polymer increases, the sweat resistance of the resulting films decreases slightly.

[0300] ④ For formulations that do not contain sterols and / or sterol derivatives but contain polymers, the sweat resistance of the resulting film gradually decreases as the amount of polymer increases.

[0301] (9) Stability

[0302] "Stability" is defined as the stability of a water-in-oil system at 5-40℃ for one week, including its viscosity, appearance (uniformity, fineness), and odor.

[0303] Test method: The example sample was placed in a transparent glass bottle and placed at 5℃, 25℃, and 40℃ for one week respectively (the worst evaluation result under the three temperature conditions was taken as the final result; that is, if any temperature condition showed a poor stability rating, the example was judged to have poor stability). One quality personnel evaluated its appearance and odor, and measured the viscosity value after one week, comparing it with the initial viscosity value. Viscosity decrease = (initial viscosity value - viscosity value after one week) / initial viscosity value 100%, stability is determined based on the evaluation results.

[0304] Experimental evaluation criteria: O: Viscosity decreases by less than 20%, with no change in appearance or odor, and good stability.

[0305] △: Viscosity decreased by 20%-30%, and there were slight changes in appearance and odor, which are within acceptable range and the stability is qualified.

[0306] X: Viscosity decreases by more than 30%, appearance and odor change significantly, and stability is poor.

[0307] The results are shown in Table 23 below.

[0308] Table 23

[0309] Based on the table above, we can see that: ①The water-in-oil emulsion in this invention has good stability. Under the above conditions, the viscosity decreases by less than 30% after one week.

[0310] ② For formulations containing sterols and / or sterol derivatives but without polymers, their stability is good, and there is no significant change in stability as the amount of sterols and / or sterol derivatives increases.

[0311] ③ For formulations containing sterols and / or sterol derivatives and polymers, the stability is generally good. With the increase of polymer content, the stability does not change significantly; however, with the increase of the total amount of "sterols and / or sterol derivatives and polymers", the stability decreases slightly.

[0312] ④ For formulations that do not contain sterols and / or sterol derivatives but contain polymers, their stability decreases slightly as the amount of polymer increases.

[0313] From the above, we can see that (1) Examples 1P-4P, 8P-9P, 11P-14P and Examples 1-4, 8-9, 11-14 all used sterols and / or sterol derivatives as film-forming agents. The latter, based on the former, specifically selected the types of aqueous phase, oil phase, emulsifier, and powder. The resulting water-in-oil emulsions achieved excellent results in film formation, stability, migration resistance, water resistance, sweat resistance, film durability, and coating uniformity. Compared with Comparative Examples 1-21, which only used polymers as film-forming agents, the present invention can achieve comparable or even better results.

[0314] Taking Example 1P and Example 1 as examples, Example 1, based on Example 1P, specifically selected "6.5% aloe vera water, 3% sorbitol, and 0.5% magnesium sulfate" as the aqueous phase, "40% C9-12 alkyl, 10% hydrogenated polyisobutylene, 9% silylated silica, 5% hydrogenated methyl rosinate, 10% caprylic / capric triglyceride, and 3% phenyl polytrimethylsiloxane" as the oil phase, "polyglycerol-6 polyricinoleate" as the emulsifier, and "8.5% titanium dioxide, 1% boron nitride, and 0.5% lutein" as the powder. The water-in-oil emulsion prepared in Example 1 can achieve the following effects: excellent film formation, qualified stability, good anti-migration properties (partial color staining), good water and sweat resistance, good film durability (slight color damage), and good spreadability (the surface looks relatively uniform).

[0315] (2) Examples 5, 6, 7, 10 and 15 use sterols and / or sterol derivatives as film-forming agents. The resulting water-in-oil emulsions can achieve excellent coating uniformity, migration resistance and film durability, as well as excellent uniform peeling, conformability, toughness, film formation, water resistance, sweat resistance and stability.

[0316] The formulations of Examples 2B and 16 are the same, both using sterols and / or sterol derivatives as film-forming agents. Example 2B can achieve good migration resistance (slight staining), and Example 16 further verifies that it has good migration resistance. It also achieves excellent results in terms of coating uniformity, film durability, uniform peeling, adherence, toughness, film formation, water resistance, sweat resistance and stability.

[0317] Examples 16-27, 52-55, and 62 also used sterols and / or sterol derivatives as film-forming agents, further verifying that the water-in-oil emulsions prepared using the formulation of the present invention achieved excellent results in terms of coating uniformity, migration resistance, film durability, uniform peeling, adherence, toughness, film formation, water resistance, sweat resistance, and stability.

[0318] (3) Examples 25-a to 51-b and 56-61 use “sterol and / or sterol derivative + polymer” as film-forming agent, and the two components achieve synergistic film-forming effect in the system.

[0319] With the same amount of film-forming agent, the formulation of the present invention can achieve comparable or even better results. Taking Comparative Example 16, Example 25-a, Example 31-a, and Example 40-a as examples, the film-forming agents are respectively "polymer (1 part)", "sterol + polymer (0.25 parts + 0.75 parts)", "sterol derivative + polymer (0.25 parts + 0.75 parts)", and "sterol and sterol derivative + polymer (0.25 parts + 0.75 parts)". Compared with Comparative Example 16, Examples 31-a and 40-a can achieve comparable film-forming and stability effects, and the uniformity of peeling, adherence, toughness, migration resistance, water resistance, sweat resistance, film durability, and application uniformity can achieve comparable or even better results.

[0320] As the amount of film-forming agent increases, the uniformity of peeling and the adherence tend to decrease. The uniformity of application, migration resistance, water resistance, sweat resistance, film durability and stability are slightly reduced, but the film-forming performance is less affected. As the amount of polymer increases, the toughness of the formed film tends to approach that of the polymer film.
