[0002] This application claims priority to U.S. Provisional Application No. 63 / 387,848, filed on December 16, 2022, entitled "MICELLAR BI-PHASE MAKEUP SPRAY IN A NON-AEROSOL FINE MIST PACKAGING", and French Application No. FR2303507, filed on April 7, 2023. The entire contents of these applications are incorporated herein by reference. Technical Field
[0003] The present invention relates to a makeup removing composition, and more particularly to a non-aerosol spray micellar bi-phase makeup removing composition. Background Art
[0004] Removing heavy makeup has always been a challenge and a pain point for consumers, especially for waterproof mascaras, long-lasting foundations, and longer-lasting lip products. Typical makeup removing products are unable to effectively remove heavy makeup, thus requiring repeated tugging and rubbing on the skin and / or delicate eye area, which can cause irritation. Some oil-based makeup removing products can easily remove makeup, but they can cause discomfort and greasiness to the skin. In addition, many commercially available makeup removing products require the use of wipes or pads for application, and can be cumbersome and result in product waste due to the saturation or dripping of the pads.
[0005] Spray-type products are easier to apply and can be applied more evenly, and then manually rubbed without wipes / pads, thus avoiding tugging on sensitive tissues. The main drawback of existing spray formulations is that they contain large amounts of oils, which can create a greasy feeling and leave the skin feeling far from the fresh and clean effect that most consumers desire. Other undesirable components in current makeup removing products include alcohols (which can cause dry skin), as well as sulfate-based surfactants, silicones, VOC propellants, and other synthetic components, which are less appealing to consumers seeking products containing natural components.
[0006] Therefore, there is a need for a composition in spray form that will provide easy and efficient makeup removal, leaving the skin feeling clean and fresh after use, and without the use of silicones, alcohols, and sulfates. Summary of the Invention

[0055] "Keratin matrix" and "keratin tissue" each include, but are not limited to, skin, hair, and nails.
[0056] "Cosmetically acceptable" means a vehicle that is compatible with any horny substrate.
[0057] "Silicone-free" means that, based on the total weight of the makeup remover composition, it contains less than 5% by weight, or less than 4% by weight, or less than 3% by weight, or less than 2% by weight, or less than 1% by weight, or less than 0.1% by weight of silicone, such as silicone polymers, for example selected from dimethicone and other silicone oils, and silicone elastomers.
[0058] "Stability" is demonstrated by one or both of naked-eye or microscopic examination. For the purposes of this article, a composition shows physical stability, does not show phase instability, and maintains two stable phases that are mixed essentially only by agitation. In various embodiments, the compositions of the present invention remain stable at a temperature of about 4°C to about 45°C for at least one month, or at least two months or longer, or any value, range, or sub-range therebetween. In some embodiments, the makeup remover composition is stable at 25°C for at least one month, or at least two months, or at least three months or longer, or any value, range, or sub-range therebetween. In some embodiments, the makeup remover composition is stable at 37°C for at least one month, or at least two months, or at least three months or longer, or any value, range, or sub-range therebetween. As disclosed and exemplified herein, the makeup remover composition is stable at 4°C for at least one month, or at least two months, or at least three months or longer, or any value, range, or sub-range therebetween. And as disclosed and exemplified herein, the makeup remover composition remains stable through at least 10 freeze-thaw cycles.
[0059] According to the present disclosure, the compositions of the present invention overcome the disadvantages of the prior art and provide unexpected benefits, including easy overall makeup removal, easy removal of liquid foundation, leaving the skin feeling clean, fresh, soft, and smooth, easy removal of mascara (ordinary and waterproof types) by gentle wiping, and leaving no greasy feeling or residue.
[0060] In some embodiments, the makeup remover composition is a silicone-free, alcohol-free two-phase makeup remover in a spray-form product that is non-aerosol and produces a fine mist, wherein the aqueous phase is proven to be a micellar technology and the ingredients are mainly natural or nature-based. In some embodiments, the makeup remover composition is a two-phase system having 50% oil and 50% water (by mass).
[0061] In various embodiments, the makeup removing composition is shaken or stirred immediately before application to form an emulsion. In some embodiments, the makeup removing composition of the present invention exhibits phase separation after shaking. In some embodiments, upon stirring, the makeup removing composition forms a milky white single phase, which separates back into three or more distinct phases over a period of up to 24 hours. In some embodiments, the makeup removing composition of the present invention exhibits phase separation after shaking, wherein after stopping stirring, a slow initial phase separation is shown to achieve a sufficiently uniform emulsion before dispensing. In some embodiments, the makeup removing composition of the present invention shows clear container walls with very few visible droplets to the naked eye after stopping stirring, with substantially no adhering or trailing layer on the container walls and no or very few visible droplets at any phase interface. In some embodiments, the makeup removing composition shows excellent ability to remove long-lasting mascara and long-lasting foundation.
[0062] Spray delivery of the makeup removing composition allows for more contact time of the composition on the skin, most effectively removing makeup. The optimized oil-to-water ratio within the ranges disclosed and exemplified herein provides an ideal makeup removing effect for all types of cosmetics. The optimized water content as disclosed and exemplified herein eliminates residues on the skin, especially compared to anhydrous, highly oily and silicone-containing compositions. The optimized combination and composition of hydrocarbons of different chain lengths in the oil phase provide an ideal makeup removing effect, especially for waterproof cosmetics, most especially waterproof mascara.
[0063] Compared to a reference product containing a propellant, silicone, alcohols and other less desirable ingredients, the makeup removing composition according to the present disclosure differs from the reference in that it is dispensed as a fine mist without using an aerosolizing propellant upon leaving the aerosol package, providing a pleasant mist and enhanced stability. Due to the lack of silicone, the makeup removing composition addresses the greasiness and oiliness after use, which are the main areas of negative reviews for competing products. In addition, the makeup removing composition does not contain irritating chemicals (silicone, alcohols, parabens, fragrances, sulfates). Compared to traditional micelles without a spray, the spray form of the makeup removing composition is most effective in removing makeup. This biphasic nature removes all types of cosmetics at once, including long-lasting mascara. In addition, as exemplified herein, compared to 100% anhydrous competing formulations, the aqueous phase of the makeup removing composition is micellar, showing loosening of heavy makeup and no greasy residue, and further enhancing the cleaning ability. The makeup removing composition is gentle on the skin, non-irritating to the skin and eyes, and provides a clean skin surface to reduce the need for rinsing after application, thereby reducing water consumption.
[0064] Through expert evaluation of the makeup removal effect, the makeup removal composition according to the present disclosure shows comparable performance to competing silicone-containing anhydrous compositions in removing liquid foundation and is excellent in removing eye and lip cosmetics. Consumer tests also show that the makeup removal composition is more popular than the competing benchmark and does not leave any greasy residue. And the makeup removal composition is also rated highly efficient in removing mascara and is gentle on the skin. In vitro tests prove that the composition does not adversely affect the skin condition, and the osmotic pressure data together with the clinical tests indicate that the makeup removal composition is non-irritating to the eyes.
[0065] According to various embodiments, the makeup removal composition according to the present disclosure comprises: an oil blend comprising one or more branched or straight-chain liquid alkanes having a carbon chain length of C11 to C20, the branched or straight-chain liquid alkanes comprising isocetane and isododecane, and one or more emollient esters; at least one polymeric thickener for water-based systems; at least one polyglycerol nonionic surfactant; and water, in a biphasic micellar system comprising an oil phase and an aqueous phase, the aqueous phase comprising water present in an amount of about 30 wt% to about 70 wt% of the makeup removal composition, wherein the water and the oil are present in a water-to-oil ratio of about 1.5:1 to about 1:1.5. The removal of the composition can be accomplished by wiping without the need for rinsing or washing as is typically required for compositions loaded with oils and surfactants such as the benchmark.

[0155] Table 13: Stability Test
[0156]
[0157] Example 7: Osmotic Pressure Test
[0158] Table 14: Osmotic Pressure
[0159]
[0160] The osmotic pressure of the aqueous phase was tested according to Var 9, where the aqueous phase also contained a colorant, a fragrance, and 0.02% hydroxyethyl cellulose. Briefly, the equipment used included an automatic osmometer: OSK 40BU201 (Ogawa-seiki), and the test protocol included preparing the composition; shaking 20 times and allowing to stand for at least 8 hours (e.g., overnight); extracting the aqueous phase and measuring the osmotic pressure with an osmometer (unit of measurement: mOsm / l, number of molecules per liter of test material).
[0161] Therefore, there is a close transfer relationship between the tested compositions and Var 9 and INV 1 (the latter two only vary in oil / water concentration). It is understood in the art that based on the knowledge that the osmotic pressure value of tears is in the range of 260 - 290 and the closer the osmotic pressure (mOsm / l) of the product is to this range, the milder the product is to the eyes, the osmotic pressure can be used as an indirect way to evaluate whether the preparation may be irritating to the eyes. Therefore, since the value of 315 mOsm / l is close to the osmotic pressure of tears, it is concluded empirically that the listed preparations are suitable for use as eye makeup removers around the eyes without causing discomfort. These results have been confirmed in clinical studies, which have shown that the study subjects did not report skin irritation or mention any eye irritation. According to various embodiments, the osmotic pressure is from about 260 to about 350 mOsm / l, and in some embodiments from about 300 to about 330 mOsm / l.
[0162] Although consumer tests have shown that the compositions of the present invention are generally non-irritating to the skin and eyes, this osmotic pressure test more specifically shows whether it is mild to the eyes, which is a key part of the makeup removal process.
[0163] Example 8: CMC surface tension test
[0164] Using Var 9 of the present invention, the critical micelle concentration was evaluated to demonstrate the concentration of surfactant in the bulk phase above which aggregates of surfactant molecules, micelles, begin to form. The measurement of CMC surface tension was carried out on a tensiometer. Now referring to Figure 1 , the curve shows a decrease in the slope of the surface tension, enters a plateau and the surface tension becomes constant. The intersection of the decreasing slope and the surface tension plateau indicates the presence of micelles. The shape of the curve demonstrates that the aqueous phase of the present invention 1 tested is micellar.
[0165] Example 9: In vitro study: Evaluation of the effect of makeup removal dissolving atomizing spray on skin barrier function in vitro using biophysical tests and zein protein model
[0166] The purpose of this experiment was to demonstrate the effect of the makeup remover on stratum corneum (SC) lipids and proteins, and to demonstrate the effect of different formulation components (i.e., surfactants, humectants, etc.) on the mildness potential of the cleanser.
[0167] This study also demonstrated the performance of the compositions of the present invention (INV 1) in DSC, TEWL and zein tests.
[0168] The mildness of the makeup removal dissolving atomizing spray INV 1 was evaluated in vitro. In summary, INV 1 falls within the target mildness region (roughly delimited by the light green rectangle), where it neither disturbs lipids (DSC) nor increases water loss (TEWL).
[0169] Permeation of water vapor through the SC (in vitro TEWL)
[0170] The surface of the SC sample was cleaned with isooctane and placed in the sample holder for TEWL. The sample holder was then immersed in Evian water to wet the SC and dried in the ambient atmosphere for at least 1 hour. The surface of the SC sample was pre-wetted with a mixture solution of 10 μl of water and n-propanol (8:2) per sample, and then conditioned in a glove box under a controlled atmosphere (30 °C, 30% RH) for 8 hours. The control TEWL measurement value "T0" was recorded. Then the SC sample was immersed in a detergent formulation diluted 4-fold (25%) with water for 2 hours, gently stirred on a shaker, washed three times in succession with water rinses, and the sample was left at room temperature for at least 4 hours to ensure drying. Then the SC sample was placed in a temperature and humidity control chamber and equilibrated at 30 °C and 30% RH. After equilibration overnight, the TEWL measurement value "T1" was recorded.
[0171] Measure the water flow through the SC sample located above the water tank. The measurement was carried out in a glove box maintained at 30 °C and 30% RH using a hygrometry probe connected to a robotic sample holder and a data acquisition system Dermalab. The hygrometry probe includes two humidity sensors at different heights in a cylindrical probe chamber, so that the humidity gradient can be measured and used to calculate the flux of water vapor. The measurements were carried out before and after processing each sample, so each sample served as its own control to ensure robust measurements.
[0172] Reference Figure 2 And Table 15, which provides the test results shown below. Due to the high inherent variability of the SC matrix, the results are expressed as the relative change in TEWL for each sample: Δ(TEWL) = (T1 - T0) / T0 × 100%. A positive change corresponds to a diffusion effect (weakening of the barrier function), and a negative value corresponds to an occlusion effect. The average value is represented by an open square for reference.
[0173] Evaluation of intercellular SC lipid disorder by DSC
[0174] After the TEWL measurement, the same samples were used for DSC analysis after re-equilibration at 75% RH and 25 °C for 4 hours.
[0175] The DSC pan was placed on an analytical balance and weighed. The SC sample was removed from the glove box / temperature and humidity chamber and the sample was removed from the sample holder. Two pieces of SC were rolled together and placed in the weighed DSC pan and sealed using a press. The weight of the DSC pan was recorded and subjected to DSC analysis.
[0176] Measurements were carried out using an aluminum-sealed pan, heating from 10 °C to 110 °C at a rate of 5 °C / min.
[0177] Reference Figure 2 and Table 15, which provides the test results as shown below. The linear combination of the measured displacements of the T2 and T3 transitions for each treatment was used as the measure of post-treatment SC lipid disorder: ΔT 有效值 = 0.7ΔT m (T2) + 0.3ΔT m (T2). The T2 transition was given a higher weight because, by accepted understanding, it is the primary criterion for lipid disorder; the contribution of T3 was also included.
[0178] Protein solubility was evaluated by the zein test
[0179] The irritation of surfactants was evaluated by using the zein solubility test, where zein is a yellow corn protein similar to keratin present in the skin, has limited solubility in water, and is denatured (dissolved) by surfactants. The ability of surfactants to denature and dissolve zein is related to their skin irritation potential. Soluble zein was measured using a spectrophotometer by the modified Lowry method. Absorbance is related to the solubility of zein and can thus be considered as a measure of the irritation potential or irritancy of the product. The irritation of the analyzed samples was graded, and a 1.5% sodium lauryl sulfate (SLS) solution was used as a positive control for comparison. The irritation data of the samples were expressed as a percentage of the SLS score.
[0180] The percentage of zein score calculated for the corresponding blank is provided in Table 15 below. The ranking of the samples based on the irritation (zein score %) analyzed relative to SLS is shown in Figure 2 . Now refer to Figure 2 , which shows that the zein score is a function of the DSC and TEWL scores, as explained above. The zein score for Invention 1 was 48, just below the cusp of strong protein denaturation and falling into the upper right corner of the plotted rectangle, indicating that it is within the range considered a mild formulation. The zein scores for the compositions according to the present disclosure were from about 88 to about 13, which was accomplished by using the surfactants according to the present disclosure and avoiding irritating surfactants that would cause lipid disorder and high zein solubility.
[0181] A cleaner map was plotted based on three mildness tests
[0182] The results of the three above-mentioned tests (TEWL, DSC, and zein) can be conveniently combined in a single graph to visually represent the performance of each formulation based on these three metrics. In the following graph, the abscissa shows the effect on the barrier property related to water penetration (TEWL), and the ordinate shows the effect on lipid order (DSC). The light green rectangle corresponds to the target mildness region where neither SC penetration nor lipid disorder occurs. The zein score is represented by the color of the data points, with a red shade indicating a high score (strong protein dissolution / denaturation) and a green shade indicating a low score (little protein dissolution / denaturation).

[0185] Example 10: Clinical Study: Study A
[0186] A clinical study was conducted to compare the makeup remover of the present invention with a commercially available benchmark and other commercially available spray and non-spray makeup removers.
[0187] Clinical Study A: Comparison 1 is a continuous mist that glides over the skin and immediately dissolves all makeup upon contact without leaving the skin feeling tight or dry. This droplet-free, ultra-fine mist is the secret of Comparison 1 to easily remove full makeup. The formulation has calming jojoba and brightening rosehip oil to soothe the skin, and the fragrance notes of green tea, cucumber, and rose to refresh the skin. The composition of the present invention was evaluated relative to this competitive benchmark.
[0188] Method ■ Blind sequential univariate design ■ 2 products ■ INV 1 ■ Comparison 1 ■ Recruited online and arranged in person ■ Used for 5 days, with online surveys and videos taken after using each product
[0189] Recruitment criteria ■ N = 37, women ■ Age 18 - 55 years old ■ Current users remove makeup 5 days or more per week – in any form ■ Cannot use only makeup removal wipes ■ Must be a user of waterproof mascara (can be a dual user, but agrees to use WP for 10 days), and long-lasting foundation and / or lipstick ■ Willing to use spray makeup remover ■ Users in the mass and / or luxury markets ■ All skin types: oily, dry, normal, combination ■ All skin tones ■ All ethnicities ■ Standard safety screening
[0190] Exclusions: ■ Users who only use makeup removal wipes ■ Allergies or known sensitivity to skin care products or cosmetics ■ Currently receiving care from a facial dermatologist ■ Very / extremely sensitive skin and eyes ■ Prone to severe acne ■ Have had facial surgery in the past 3 months ■ Pregnancy or lactation
[0191] Test: INV 1 relative to Comparison 1: ReferenceFigure 3 This graph details the consumer's sensory experience journey and reports the overall feeling based on the tests conducted in the above-mentioned clinical study. The specific data points are described in Table 16.
[0192] Referring again to Figure 3 it is noted that there are significant differences in the amount and nature of the oil content in these compositions. Comparison 1 is anhydrous, containing silicone oil / silicone and a strong surfactant. INV 1 shows an overall satisfactory user experience journey, with the opportunity to improve the amount of rubbing required for complete removal. Comparison 1 is similar to INV 1 before and during the use journey. However, Comparison 1 is less satisfactory and less popular after use because it makes the skin feel clean, leaves no residue, and requires washing the face after application, which is unusual.
[0193] As shown, INV 1 is superior to Comparison 1 in terms of product consistency and shows a very large advantage in the post-use feeling. Consumers prefer this product over the top benchmark Comparison 1 because the formulation INV 1 of the present invention has a clean appearance, makes the skin feel comfortable (no face washing is required afterwards), and is gentle on the face.
[0194] Users consider both products to be effective, gentle on the skin, and provide a quick removal method. It is worth noting that although the overall performance of the present invention and the comparison is proven to be comparable, the main benefit of the present invention is the surprisingly effective removal in a water-based composition that does not require rinsing after use but leaves the skin without a greasy or oily feeling.

[0199] Comparison 1 and INV 1 were evaluated. The target N = 18 white female volunteers; aged 18 - 60 years, medium to long eyelashes, no drooping eyelids, and the test product was Maybelline Colossal Big Shot Ultra Black Waterproof Mascara.
[0200] All subjects applied the cosmetics in the same manner according to a standard procedure including prior cleansing. The removal of mascara for all subjects was completed through the same standard procedure.
[0201] The invention 1 mentioned in this embodiment contains the same preparation in a specific package (SP).
[0202] The different actuators result in a great difference in the volunteers' experience. Comparison 1 (aerosol spray) is a light mist that looks as if nothing has been applied to the face. Sometimes, the volunteers even ask if there is anything. INV 1 has a stronger wetting effect during application. The subjects can feel the product on their faces, indicating that it is delivered to the skin.
[0203] Dry - hand emulsification is the key to making the spray makeup remover work best. After making the first round of circular motions around the eyelashes, it is obvious that the product decomposes immediately. Comparison 1 spray decomposes slightly faster due to the amount of oil in it. The two products look and are reported to feel different on the skin. Comparison 1 has an oily feeling / oily appearance on the face. Due to the large mist, oily particles are left around the hairline, making the hair greasy (which may or may not be acceptable to consumers). Once applied, INV 1 has a very wet appearance, decomposes easily during emulsification, is easily removed overall, and has very little resistance on the eyelashes during removal with a cotton pad because the product itself does not slide much (not noticed by consumers).
[0204] In summary, when emulsified with dry hands, both makeup remover sprays perform efficiently. Comparison 1 performs slightly better than the market - leading Comparison 2. INV 1 performs similarly to Comparison 2 and Comparison 3. The biphasic and spray formulations use different removal methods. However, in general, both products are highly efficient waterproof mascara removers.

[0206]
[0207] Example 12: Clinical study C: Mascara removal; Evaluation of removal effect
[0208] Tests were conducted to demonstrate the performance of the new packaging options of INV 1. The target N = 6 white female volunteers; aged 18 - 60 years, medium - long eyelashes, no drooping eyelids, test products INV 1, INV 1CP, and Comparisons 1 - 7, and Maybelline Colossal Big Shot ultra - black waterproof mascara.
[0209] The invention 1 mentioned in this embodiment includes the same preparation in different packages (SP and CP).
[0210] According to the standard procedure including prior cleansing, all subjects applied cosmetics in the same way. The mascara removal for all subjects was completed through the same standard procedure.
[0211] In summary, compared to the original prototype makeup remover INV 1CP, the makeup removing effect of INV 1 with a spray device similar to Inv 8 is much lower. The original prototype is a highly efficient heavy makeup mascara remover. However, after INV 1 replaced the pump, the efficiency dropped to a medium level. The formula is the same, but the impact of the amount of product sprayed onto the target area is different. The pump of INV 1 sprays everywhere around the face, but it is not close enough to the eyes to achieve proper saturation for removal, so the effect is lower. Two competing products, Inv 5 and 6 makeup remover sprays, perform like medium to highly efficient heavy makeup mascara removers. Inv 8 is slightly more efficient than Inv 7, with a difference of 1 makeup remover cotton (median).

[0213]
[0214] Example 13: Clinical Study D: Mascara removal; Evaluation of removal effect
[0215] Tests were conducted to demonstrate the performance of new packaging options of INV 1 with specific different actuators (CP, HDM, and OP). The target N = 6 white female volunteers; aged 18 - 60 years, medium to long eyelashes, no drooping eyelids, test products INV 1, INV 1CP, INV1HDM, and INV1OP, and comparisons 1 - 7.
[0216] The invention 1 mentioned in this example includes the same preparation in different packages (SP, CP, HDM, and OM).
[0217] According to the standard procedure including prior cleaning, all subjects applied cosmetics in the same way. The mascara removal of all subjects was completed through the same standard procedure.
[0218] In summary, when emulsified with dry hands, both makeup remover sprays perform efficiently. Comparison 1 performs slightly better than the market - leading makeup remover Comparison 2. The 2 test formulas (INV 1HDM & INV 1OM) perform similarly to the biphasic products Comparison 2 and Comparison 3. The biphasic and spray formulations use different removal methods. However, in general, both products are highly efficient waterproof mascara removers.

[0220]
[0221] These results provide evidence that the fine mist spray packaging produces the same high efficiency in a biphasic composition having an aqueous phase and an oil phase as a competing product (Comparison 1) having a 100% oil composition.
[0222] Example 14: Clinical Study E: Evaluation of the atomizing spray pump container of the present invention (INV 1) relative to a reference aerosol (Comparison 1) (propellant-based) spray
[0223] A study was conducted to explore consumers' feelings and preferences for the formulation and packaging by evaluating the entire product experience journey, including application, texture, feel, final appearance, durability, and removal.
[0224] Method: A 14-day home use test was conducted; 42 female users aged 18 - 30 years, with a mix of different ethnicities, skin types, and skin tones, users of both mass and luxury brand cosmetics had a 4-day active period, and the INV1 and Comparison 1 products were tested in two consumer markets using a randomized sequential one-way design; a product usage protocol was provided, including specific instructions for product application, makeup, and mascara removal; the subjects provided responses to questions regarding product application and sensory experience.
[0225] The results are listed in Table 20 below.
[0226] Test: INV 1 relative to Comparison 1: Reference Figure 4 , and the chart details the experience journey of consumers using the dispensing atomizing pump of INV 1 and the aerosol spray device of Comparison 1.
[0227] Refer again to Figure 4 , noting that there are significant differences in the amount and nature of the oil content in these compositions, where Comparison 1 is anhydrous, including silicone oil / silicone and strong surfactants, and INV 1 dispensed in the atomizing pump showed an overall satisfactory user experience, and both products showed opportunities for improvement in the initial oily feel on the face and on the skin upon direct application.
[0228] Users found both products to be effective, gentle on the skin, and provided a quick removal method. Notably, the overall performance of the present invention and the comparative dispensing containers was proven to be comparable, and the main benefit of the present invention is the elimination of the use of aerosol propellants and an overall reduction in the use of silicone and surfactants without compromising effectiveness.
