Description

Technical Field

[0001] This technology involves multi-layered makeup protective cosmetics, etc. Background Technology

[0002] As consumers, they hope that their makeup will not smudge due to sweat or friction with clothing.

[0003] For example, Patent Document 1 discloses a method for providing a topical application agent for preventing makeup from fading. This method significantly improves the durability and secondary adhesion of makeup by applying a second layer of makeup to eye makeup materials, which are mainly used for eyeliner, mascara, eyebrow pencil, etc., for use around the eyes, eyelashes, and eyebrows (claim 1).

[0004] In addition, Patent Document 2 proposes a water-based or water-in-oil type spray cosmetic, characterized in that (A) it contains a specific water-soluble thickener and is filled in a pump-type spray container with an aperture of Φ0.25 to Φ0.55 (claims 1, 3, paragraph

[0024] , [Table 1]).

[0005] For example, Patent Document 3 provides a skin cosmetic material, particularly in the form of a lotion or cream, which can be used on top of a makeup foundation to moisturize the skin. It has excellent long-term stability and will not cause the foundation to deform even when applied to a strip of cheek. It also has excellent moisturizing effects over time (paragraphs

[0001] and

[0002] ).

[0006] For example, Patent Document 4 proposes a multi-layered makeup protective cosmetic, which, according to claim 1, contains ingredients (A) to (C), where (A) is an oil-soluble film-forming agent, (B) is 40 to 95% by mass of water, and (C) is a volatile oil agent, and is sprayed onto the makeup for use.

[0012] Patent Document 4: WO2020 / 175398 Summary of the Invention

[0013] The problem that the invention aims to solve

[0014] The main objective of this invention is to provide a multi-layered makeup protective material that forms a film quickly and has a non-sticky feel, preventing the spray nozzle or spray mouth from becoming clogged over time.

[0015] Methods for solving problems

[0016] Through in-depth research, the inventors discovered that by preparing a composition containing (A) an oleophilic resin, (B) ethanol, (C) a metal salt, and (D) a low-viscosity, non-volatile oil, a multi-layered makeup protective material can be provided. This material exhibits good film-forming speed and a non-sticky feel, preventing clogging of the spray nozzle or spray applicator over time. Thus, the present invention was completed. The present invention is as follows.

[0017] This invention provides a multi-layered makeup protective material containing component (A) an oleophilic resin, component (B) ethanol, component (C) a metal salt, and component (D) a kinematic viscosity of less than 300 mmHg at 25°C. 2 Low viscosity, non-volatile oil agent per second.

[0018] Invention Effects

[0019] According to the present invention, a multi-layered makeup protective material is provided, which has a good film-forming speed and a non-sticky feel during use, and can prevent the spray nozzle or spray nozzle from becoming clogged over time. Detailed Implementation

[0020] The preferred embodiments for implementing this technology are described below. It should be noted that the embodiments described below represent an example of a representative implementation of this technology and are not intended to narrowly interpret the scope of this technology. It should be noted that, unless otherwise specified, percentages in this specification refer to mass percentages (mass / mass%). Furthermore, the upper (and lower) limits and lower (and higher) limits of each numerical range (~) can be arbitrarily combined as needed.

[0021] 1. About this technology

[0022] The inventors have conducted in-depth research on multilayer protective compositions containing oily resins that offer expected makeup protection. Because this technology involves multilayer compositions, the appearance of the compositions differs from that of the cosmetics in Patent Documents 1-3, and the concept or direction of the composition naturally differs significantly.

[0023] Regarding multi-layered makeup protective cosmetics using oil-soluble film-forming silicone resins, the inventors have discovered that multi-layered compositions further incorporating 40-95% water and volatile oils into the oil-soluble film-forming silicone resin exhibit good mist fineness and makeup protection, but feel sticky after application. Furthermore, with continued use of spray containers, lipophilic resin precipitates near the outlet, causing clogging of the spray nozzle. The present invention proposes that while using volatile oils in the composition results in good film-forming speed during use, the spray nozzle will eventually become clogged. Moreover, the inventors have found that, as shown in Reference Example 1 below [Examples], even compositions further incorporating ethanol containing lipophilic resin, ethanol, water, and volatile oils still experience clogging of the spray nozzle over time.

[0024] Therefore, the main objective of this technology is to provide a multi-layered makeup protective material that forms a film quickly and has a non-sticky feel, preventing the spray nozzle or spray tip from becoming clogged over time.

[0025] Furthermore, through in-depth research, the inventors discovered that by formulating a composition containing an oleophilic resin, ethanol, a metal salt, and a low-viscosity non-volatile oil, a multi-layered makeup protective cosmetic material with a non-sticky feel and preventing long-term clogging of the spray nozzle or spray applicator can be provided (Examples 1-28). Moreover, this technology has the following excellent advantages: even without the use of volatile oils, it exhibits a good film-forming speed of the oleophilic resin (Examples 1-4, etc.). Furthermore, this technology also has the following excellent advantages: even when containing medium-to-high viscosity non-volatile oils different from the low-viscosity non-volatile oils, it can provide a multi-layered makeup protective cosmetic material with a good film-forming speed and an excellent non-sticky feel during use, while preventing long-term clogging of the spray nozzle or spray applicator (Examples 25 and 26). Furthermore, this technology offers the following advantages: even when containing volatile oils, it provides an excellent non-sticky feel, prevents clogging of the spray nozzle or spray tip over time, and produces a multi-layered makeup protective cosmetic with good film-forming speed during use (Examples 27 and 28). It should be noted that the compositions of this technology can be used as cosmetics or topical skin agents, and the ingredients, composition, and amounts detailed below may be appropriately employed.

[0026] This technology provides multi-layered cosmetics with makeup protection effects. These cosmetics can be topical agents or compositions. Furthermore, this technology offers the following advantages: users can use it on top of regular makeup, on the skin before makeup application, or during makeup application, preventing or inhibiting makeup from fading and providing makeup protection. Additionally, it prevents secondary adhesion to clothing and masks. Moreover, even when mixed with foundation, blush, eyeshadow, or applied after spraying onto makeup brushes, cotton pads, or other makeup application methods, it can still prevent or inhibit makeup from fading and provide makeup protection. Therefore, this technology meets the needs of consumers who want to improve the durability of specific makeup applied to the skin or face using handheld makeup products. Furthermore, this technology can be appropriately applied or used to achieve the desired makeup look or during or after makeup application, depending on the makeup application situation, method, repair (makeup touch-up), steps, techniques, or skills. It should be noted that this technology prevents makeup from adhering to clothing or masks that come into contact with the skin during makeup application, thus providing makeup protection. While various application methods are possible, from the perspective of makeup protection, it is preferable to apply it to the makeup itself, to the skin before applying makeup, or during the makeup application process.

[0027] Furthermore, the inventors have discovered that by using lipophilic resins, a film with excellent blocking effect against atmospheric particles such as pollen, PM2.5, and yellow sand can be easily formed (Patent Document 4: WO2020 / 175398). As shown in the [Examples] below, by using a multi-layered composition containing at least a lipophilic resin on makeup, makeup can be prevented from fading for a long time. This technology, when used on skin before or after makeup application, can be used not only to protect makeup but also as a composition for protecting the skin from air pollution, pollen, PM2.5, and atmospheric particles. In addition, this technology has the following advantages: various particles are less likely to adhere to the skin surface or makeup surface using the skin protection composition related to this technology.

[0028] The following is a detailed description of this technology.

[0029] 2. The multi-layered makeup protection cosmetic involved in this embodiment

[0030] This embodiment provides a multi-layered makeup protective material containing component (A) an oleophilic resin, component (B) ethanol, component (C) a metal salt, and component (D) a low-viscosity, non-volatile oil. The low viscosity of component (D) is preferably a kinematic viscosity of less than 300 mmHg at 25°C. 2 / s. This results in a non-sticky feel and prevents clogging of the spray nozzle or spray tip over time. Furthermore, it offers the advantage of a fast film-forming speed during use.

[0031] In addition to makeup protection, makeup protectants can also be used as skin protection compositions or skin protection cosmetics. Furthermore, makeup protectants can be used for protective measures against atmospheric particles such as PM2.5 and pollen, or for anti-adhesion applications.

[0032] This embodiment is preferably used by spraying it on the face. This embodiment can spray out a fine mist, so it is easy to form an even film on the face or makeup, which is also good from the point of view of makeup protection.

Furthermore, in this embodiment, the mass ratio (C) / (A) of component (C) to component (A) is preferably 0.02 to 20. In this embodiment, the mass ratio (A) / (D) of component (A) to component (D) is preferably 0.01 to 6. Furthermore, in this embodiment, it is preferable to also contain a volatile oil agent. In addition, this embodiment may also contain a medium-to-high viscosity non-volatile oil agent.

[0034] The following provides a detailed description of the multi-layered makeup protective cosmetic material according to this embodiment. It should be noted that there are no particular limitations on the ingredients used in this embodiment, as long as they are generally applicable to cosmetics or topical skin agents.

[0035] <2-1. Oleophilic resins>

[0036] The lipophilic resin used in this embodiment (hereinafter also referred to as "component (A) lipophilic resin" or "component (A)") is not particularly limited as long as it can generally be used in cosmetics or topical skin agents. Preferably, it is a lipophilic resin that can be dissolved in oils or swell and disperse uniformly in oils, and can be used in general cosmetics or topical skin agents. From the viewpoint of makeup protection effect, a lipophilic resin is preferred. More preferably, this lipophilic resin is an oil-soluble film-forming lipophilic resin, which is soluble in oils such as volatile oils and can form a film. It is even more preferably a resin that can be used in general cosmetics or topical skin agents.

[0037] In this specification, the term "resin" in "lipophilic resin" refers to an adhesive substance obtained from tree bark, encompassing polymeric compounds, including natural resins, semi-synthetic resins, and synthetic resins, regardless of their origin, and is commonly used in cosmetics or topical skin preparations. The term "lipophilic" in "lipophilic resin" refers to its property of being soluble in oils or swelling and uniformly dispersed in oils.

[0038] As component (A), the lipophilic resin is not particularly limited, but examples include polymethylsilsesquioxane, polypropylsilsesquioxane, trimethylsiloxysilicic acid, trifluoroalkyl dimethyltrimethylsiloxysilicic acid, (trimethylsiloxysilicic acid / polydimethylsiloxane alcohol) crosspolymer, (polydimethylsiloxane / vinyltrimethylsiloxysilicic acid) crosspolymer, (polydimethylsiloxane / vinylpolydimethylsiloxane) crosspolymer, (vinyldimethyl / trimethylsiloxysilicic acid / polydimethylsiloxane) crosspolymer, (vinyldimethyl / trimethylsiloxysilicic acid stearyl polydimethylsiloxane) crosspolymer, etc., and other organosilicon resins; (styrene / acrylate) copolymers, (cyclohexyl methacrylate / ethyl methacrylate) copolymers, etc. (Meth)acrylic resins such as (meth)acrylic acid copolymers; (meth)acrylic acid-organosilicon graft polymers such as (acrylate / polydimethylsiloxane) copolymers and (acrylate / polytrimethylsiloxymethacrylate) copolymers; dextrin fatty acid esters such as dextrin isostearate; α-olefin / vinylpyrrolidone copolymers such as (VP / eicosene) copolymers; organosiliconized polysaccharide compounds such as pullulan tris(trimethylsiloxy)silylpropylcarbamate; pullulan fatty acid esters such as cardamomylated pullulan and palmitoylated pullulan; rosin-modified phenolic resins, rosin esters, and other rosin acid resins; candle resins; vinyl acetate resins; saturated or unsaturated hydrocarbon resins such as polybutene resins, polyisoprene resins, and hydrogenated resins; polyurethane resins, etc. These components (A), when combined with the components described below, can achieve good film-forming speed, a non-sticky feel, and prevent clogging of the spray nozzle or spray nozzle over time. One or more of these components (A) may be selected, preferably in combination. It should be noted that "(meth)acrylic acid" refers to "acrylic acid" and / or "methacrylic acid", and "(meth)acrylate" refers to acrylate and / or methacrylate.

[0039] As for component (A), the lipophilic resin, from the viewpoint of makeup protection effect and the fineness of the mist during application, it is preferably selected from one or more of silicone resins, (meth)acrylic resins, (meth)acrylic-silicone graft polymers, and dextrin fatty acid esters, more preferably from one or more of silicone resins, (meth)acrylic resins, and (meth)acrylic-silicone graft polymers, with silicone resins being the most preferred. In this embodiment, one of the examples of lipophilic resins can be used alone, but if two or more are used in combination, the makeup protection effect and the fineness of the mist during application are even better, and therefore more preferred. In addition, in order to improve the non-sticky feel and makeup protection effect, two or more of the silicone resins selected from the above-mentioned polymethylsilsesquioxanes can be used in combination, for example, polymethylsilsesquioxane and trimethylsiloxysilicic acid can be used in combination.

[0040] The lipophilic resin in component (A) is preferably selected from one or more of the following: polymethylsilsesquioxane, trimethylsiloxysilicic acid, (acrylate / polydimethylsiloxane) copolymer, trifluoroalkyl dimethyltrimethylsiloxysilicic acid, (polydimethylsiloxane / vinyltrimethylsiloxysilicic acid) crosspolymer, (trimethylsiloxysilicic acid / polydimethylsiloxane alcohol) crosspolymer, (polydimethylsiloxane / vinylpolydimethylsiloxane) crosspolymer, (styrene / acrylate) copolymer, (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer, and dextrin isostearate; more preferably selected from (polydimethylsiloxane / vinylpolydimethylsiloxane) crosspolymer, polymethylsilsesquioxane, trimethylsiloxysilicic acid, (acrylate / polydimethylsiloxane) copolymer, and trifluoroalkyl dimethylsiloxysilicic acid. The cross-linked polymer is selected from one or more of the following: dimethyltrimethylsiloxane, (polydimethylsiloxane / vinyltrimethylsiloxane), (trimethylsiloxane / polydimethylsiloxane), (styrene / acrylate), (cyclohexyl methacrylate / ethylhexyl methacrylate), and dextrin isostearate. More preferably, the cross-linked polymer is selected from one or more of the following: (polydimethylsiloxane / vinylpolydimethylsiloxane), polymethylsilsesquioxane, trimethylsiloxane, (acrylate / polydimethylsiloxane), trifluoroalkyldimethyltrimethylsiloxane, (polydimethylsiloxane / vinyltrimethylsiloxane), and (trimethylsiloxane / polydimethylsiloxane). As a result, the makeup protection effect and the fineness of the mist during use are better, the film formation speed is good and it has a non-sticky feel. It is also easy to avoid clogging of the spray nozzle or spray nozzle over time.

[0041] It should be noted that it is more preferable that the lipophilic resin of component (A) contains at least trimethylsilyloxysilicic acid, in which case the trimethylsilyloxysilicic acid can be combined with other lipophilic resins or different organosilicon resins.

[0042] Furthermore, among the lipophilic resins in component (A), from the viewpoint of makeup protection, film-forming lipophilic resins are preferred. Film formation refers to dissolving the lipophilic resin in a volatile oil to form a resin liquid, uniformly coating the resin liquid onto a glass plate with a certain thickness (e.g., 400 μm), and allowing the volatile oil to evaporate to form a film.

[0043] As an example of a film-forming lipophilic resin used in this embodiment, a film-forming resin can be appropriately used from the examples of lipophilic resins and compounds described in "Component (A) Lipophilic Resin" above. Preferably, film-forming silicone resins, film-forming (meth)acrylic resins, film-forming (meth)acrylic-silicone graft polymers, and film-forming dextrin fatty acid esters are used; more preferably, film-forming silicone resins, film-forming (meth)acrylic resins, and film-forming (meth)acrylic-silicone graft polymers are used. From the viewpoint of being able to form a more effective, non-sticky film resistant to sweat or sebum, film-forming silicone resins are preferred. One or more of these resins can be used.

This makes it easier to obtain better makeup protection effect, better mist fineness, non-sticky feel, clogging prevention effect, and film-forming speed. It should be noted that the above-mentioned components (A) and (B) can be combinations of examples of their respective preferred components, such as "a combination of an oleophilic resin (e.g., an organosilicon resin) and ethanol". In addition, "containing a mass ratio (B) / (A)" can be "using a mass ratio (B) / (A)".

[0054] <2-3. Metal Salts>

[0055] The metal salt of component (C) used in this embodiment (hereinafter also referred to as "metal salt of component (C)" or "component (C)") is not particularly limited as long as it can be commonly used in cosmetics or topical skin agents. Inorganic acid metal salts and organic acid metal salts are examples, and one or more of them can be used. This further improves film-forming speed, non-sticky feel, clogging prevention effect, makeup protection effect, and mist fineness, particularly enhancing film-forming speed, non-sticky feel, and clogging prevention effect.

[0062] <2-4. Low-viscosity non-volatile oils>

[0063] The low-viscosity, non-volatile oil used in this embodiment is not particularly limited as long as it is generally used in cosmetics or topical skin agents, and is unrelated to the properties of solid oils, semi-solid oils, or liquid oils derived from natural oils (animal oils, vegetable oils, oils derived from microorganisms, etc.) or synthetic oils. This results in improved film-forming speed, a non-sticky feel, clogging prevention, makeup protection, and mist fineness, particularly enhancing film-forming speed, non-sticky feel, and clogging prevention.

[0064] The term "non-volatile oil" in this specification can refer to oils that can be used in cosmetics or topical skin agents and are commercially available or purchased as non-volatile oils or non-volatile oils.

For example, it can be obtained by filling components (A) to (D) and water, as well as other suitable ingredients, into a container (e.g., a container with a dispenser, a container with a nozzle, a spray container, a finger spray container, a mist spray container, or other non-aerosol containers; aerosol containers, etc.). The components used in this embodiment can be mixed before filling, and this mixing can be done under appropriate heating (e.g., 80-95°C). In addition, the components used in this embodiment can be filled into multiple containers such as water layer containers, oil layer containers, and powder containers to form a two-component or three-component multi-component combination product. Furthermore, this embodiment can be combined with tools such as containers and coating tools. This combination can be a kit or a reagent kit. When it is a multi-component product, the user can mix the water layer components, oil layer components, powder components, etc., in the required proportions before spraying. Alternatively, this embodiment can also be made into an aerosol form using a spray agent, but from the viewpoint of ease of use by spraying onto the face, it is preferable to use a spray container that does not use a spray agent.

It may also contain powder or the like to form three or more layers. Furthermore, the multi-layered makeup protection cosmetic of this embodiment is ideally in the following state: it can be well dispersed by mixing before use with a spray, and this dispersed state can be maintained for a certain period of time. On the other hand, if left for a certain period of time, it will revert to a multi-layered form or undergo layer separation.

[0110] The multi-layered makeup protectant of this embodiment maintains good dispersion for a certain period of time after mixing, thereby enabling it to be sprayed into fine mist particles. Furthermore, this embodiment can be in a multi-layered form, exhibiting excellent spray properties and film formation due to the incorporation of an oleophilic resin, forming a combination of the aforementioned components (A) to (D) and water. In addition, this embodiment has the advantage that even without the addition of an emulsifier, the spray particles are fine, thus it can also be used as a makeup protectant without emulsifiers or with reduced emulsifier content.

[0111] Furthermore, this embodiment also has the following advantages: by combining the above-mentioned components (A) to (D), a film with high water resistance and sebum resistance due to the lipophilic resin can be formed on the applied makeup, and a long-lasting and excellent makeup protection effect can also be achieved. In addition, this embodiment can spray fine mist particles onto the entire face, forming a film with high water resistance and hydrophobicity on the entire face.

[0112] Furthermore, the viscosity (mPa·s) of the composition (preferably cosmetic) of this embodiment is preferably 1500 mPa·s or less over 1 minute when measured at 25°C using a type B viscometer and rotor No. 2 at 6 rpm, and more preferably 1000 mPa·s or less, which results in excellent mist coarseness, and is therefore more preferred.

[0132] [Multi-layered makeup protection cosmetics: Examples 1-28, Comparative Examples 1-5, and Reference Example 1]

[0133] Multi-layered makeup protectants with the compositions shown in Tables 1-3 were prepared using the following methods. They were evaluated and judged according to the evaluation methods and judgment criteria shown below, and the results are combined and shown in the table.

[0140] The compounds used in Tables 1-3 are shown below.

[0141] <Oleophilic resins>

[0142] The lipophilic resin content listed in Tables 1-3 refers to the amount of solids. The following commercially available products are added to each composition; this is the amount of solids in this case.

[0143] In addition, when commercially available products are uniformly dispersed by dissolving or swelling with an oil, a lipophilic oil is used. Furthermore, a lipophilic resin is one that dissolves after adding a solid component to 100 mL of an oil (temperature 10–20°C) of a volatile oil to a concentration of 10% and stirring. For example, a substance that can be dissolved using any oil (e.g., polydimethylsiloxane) as a solvent for the commercially available product described as component (A) can be considered a lipophilic resin. The following compounds are lipophilic resins. Furthermore, when a resin solution or a commercially available resin solution is dissolved using the same oil as described above, the film-forming property described in <2-1. Lipophilic Resins> is determined. As a result, film formation was observed in all of the following compounds, thus confirming them as lipophilic resins with film-forming properties. It should be noted that the following compounds can be used as lipophilic resins in Examples 1–6 (Examples 29–34) after Example 29, where the content of the lipophilic resin in the examples is the amount of the solid component.

[0177] It should be noted that (1) to (25) can also be filled into a container with a nozzle in a random order and shaken vigorously to obtain the composition (multi-layer makeup protection cosmetic).

[0178] <How to use the composition>

[0179] The composition used in this experiment was sprayed onto the face where foundation, eyeshadow, blush, and other makeup had been applied. After shaking the composition used in this experiment 10 times, it was sprayed 10 times onto the entire face where makeup had been applied. When evaluating the composition used in this experiment, the following evaluation method was used, for example, the evaluation method for "(2) non-sticky feel" was used, and the evaluation was performed 5 minutes (dry) after spraying.

[0180] (Evaluation Method)

[0181] Ten cosmetics evaluation professionals sprayed various multi-layer makeup protectants onto the entire face 10 times during a test involving foundation and eye makeup. The evaluations were conducted in five stages based on the following criteria: (1) speed of makeup film formation, (2) non-sticky feel, (3) clogging prevention effect, (4) makeup protection effect, and (5) fineness of the mist. For items (1), (2), and (5), evaluations were conducted during and immediately after use. For item (4), the makeup's durability was evaluated 8 hours after use, following normal daily activities. For item (3), the amount of spray at the start of use and at the end of use were compared. The average score from all evaluators was then calculated, and a final judgment was made according to the following criteria.

[0182] Evaluation Criteria

[0183] (1) Cosmetic film formation speed: How fast the cosmetic film forms after application.

[0184] (Rating): (Evaluation Result)

[0185] 4 points: A cosmetic film forms within 5 minutes after application.

[0186] 3 points: A cosmetic film forms within 5 to 7 minutes after application.

[0187] 2 points: A cosmetic film forms within 7 to 9 minutes after application.

[0188] 1 point: A cosmetic film forms within 9 to 10 minutes after application.

[0189] 0 points: No makeup film forms even 10 minutes after application.

[0190] It should be noted that after shaking the container with the nozzle filled with the composition 10 times, the composition is sprayed onto a glass plate (5cm×5cm) 10 times, and the film formation of the composition applied to the glass plate is observed.

[0191] (2) Non-sticky feel: Does it feel sticky after 5 minutes of application to the skin?

[0192] (Rating): (Evaluation Result)

[0193] 4 points: Not sticky at all.

[0194] 3 points: Almost not sticky.

[0195] 2 points: Slightly sticky

[0196] 1 point: Slightly sticky.

[0197] 0 points: Extremely sticky.

[0198] (3) Clog prevention effect: Stored at 5℃, sprayed 5 times a day at 5℃, the average spray mass of 5 sprays after the 30th day is proportional to the average spray mass of 5 sprays at the beginning of the test (N=3 average).

[0199] (Rating): (Evaluation Result)

[0200] 4 points: above 95%

[0201] 3 points: Below 95% to above 80%

[0202] 2 points: Below 80% to above 65%

[0203] 1 point: Below 65% to above 50%

[0204] 0 points: below 50%

[0205] (3) Clog Prevention Effect: Specifically, the composition used in the experiment was filled into three nozzle-equipped containers as described above, and three nozzle-equipped containers filled with the same composition were prepared and stored at 5°C for 10–12 hours. After storage, the spray mass (mg) of each container sprayed into the beaker after 5 sprays at 5°C was measured. The total amount used for the three containers was calculated, and the average spray mass (mg) of each container at the start of the experiment (day 1) was calculated based on this total amount. After the start of the experiment, the three containers were kept at 5°C and sprayed 5 times a day at 5°C. At the end of day 30, the spray mass (mg) of the sprayed into the beaker after 5 sprays was measured, and the average spray mass (mg) of each container at the end of the experiment (day 30) was calculated in the same manner as at the start of the experiment (N = 3 average). Then calculate the ratio of the average spray mass from 5 sprays at the end of the test to the average spray mass from 5 sprays at the beginning of the test (that is, [average spray mass per container at the end of the test / average spray mass per container at the beginning of the test] × 100 (%)). A score within the following evaluation result range (ratio) is used to evaluate the composition used in the test. The less clogging of the spray nozzle or spray tip caused by the composition used, and the smaller the difference between the spray mass at the end of the test and the spray mass at the beginning of the test, the closer the evaluation result is to 100%.

[0206] (4) Makeup protection effect: Whether the makeup has come off after 8 hours after application.

[0207] (Rating): (Evaluation Result)

[0208] 4 points: The makeup did not come off at all 8 hours after application.

[0209] 3 stars: The makeup barely came off 8 hours after application.

[0210] 2 points: The makeup slightly faded 8 hours after application.

[0211] 1 point: Makeup started to wear off 8 hours after application.

[0212] 0 points: Makeup severely peeled off 8 hours after application.

[0213] (5) Fineness of the mist: Does the mist feel fine when applied?

[0214] (Rating): (Evaluation Result)

[0215] 4 points: The mist particles are very fine.

[0216] 3 points: The fog particles are medium to fine.

[0217] 2 points: The fog particles are slightly large.

[0218] 1 point: The mist particles form water droplets on the skin.

[0219] 0 points: Not sprayed out in a mist-like manner

[0220] Judgment Criteria

[0221] (Average score): (Judgment)

[0222] 3.5 points or above: ◎ (Excellent)

[0223] 2.5 points or higher but lower than 3.5 points: ○ (Good)

[0224] 1.5 points or higher but less than 2.5 points: △ (Slightly unacceptable)

[0225] Below 1.5 points: × (Not allowed)

[0226] The compositions of Examples 1-28 and Reference Example 1 are multi-layered makeup protectants consisting of an upper oil layer and a lower water layer.

[0227] The compositions of Examples 1 to 28 have a viscosity of 1000 mPa·s or less at 25°C. It should be noted that the viscosity of the composition was measured using a Type B viscometer described in "Viscosity of the Composition of this Embodiment (mPa·s)" above after shaking the composition 10 times and allowing it to stand.

[0228] As shown in Tables 1-3, the compositions of this technology (Examples 1-28, Reference Example 1) can be gently and delicately sprayed onto the entire face, thus without damaging the applied makeup. Even ordinary users can easily form a moderately thick and evenly thick makeup film on the entire face. Furthermore, the compositions of this technology do not smudge even after being applied to the face for up to 8 hours, thus exhibiting high sebum resistance and excellent skin protection. Additionally, these compositions preferably contain volatile oils, and when water is included, the water content is preferably in the range of approximately 50-85% by mass, which can be adjusted to 1-95% by mass.

[0229] Furthermore, the protective compositions of this technology (Examples 1-28) contain component (A) an oleophilic resin (film-forming resin), component (B) ethanol, component (C) a metal salt, and component (D) a low-viscosity, non-volatile oil agent. Therefore, they exhibit excellent performance in terms of mist fineness, makeup protection effect, film-forming speed, non-sticky feel, and clogging prevention. Additionally, the preferred mass ratio of (B) / (A) is in the range of 1 to 200, and a more preferred range is 2 to 100. Furthermore, the preferred mass ratio of (C) / (A) is in the range of 0.1 to 20, and a more preferred range is 0.2 to 10. Furthermore, the preferred mass ratio of (A) / (D) is in the range of 0.01 to 6, and a more preferred range is 0.1 to 3.

[0230] Furthermore, protective compositions containing hydrophilic resins, volatile oils, and water are not preferred due to their stickiness and heavy feel (see Patent Document 4), but the protective composition of Reference Example 1, which contains component (C) metal salt, achieved a non-sticky feel (◎ (Excellent)). However, the protective composition of Reference Example 1 did not exhibit a clogging prevention effect. In addition, the compositions of Comparative Examples 1 to 5 did not achieve a makeup protection effect, and other evaluations were also unsatisfactory.

[0231] The protective composition of this technology (e.g., Example 1) compared to the protective composition of Reference Example 1 shows that by changing the volatile oil to component (D) a low-viscosity non-volatile oil, the clogging prevention effect changes from "× (not possible)" to "◎ (excellent)," achieving a very superior result. Furthermore, by combining a low-viscosity non-volatile oil and a volatile oil, the clogging prevention effect is not reduced, and excellent results are also achieved in terms of mist fineness, makeup protection effect, non-sticky feel, and clogging prevention effect of the spray nozzle or spray tip.

[0232] Additionally, for low-viscosity (25°C: kinematic viscosity) non-volatile oils, use 100mm. 2 When using a non-volatile oil with a viscosity of / s or less (Example 25), excellent results were obtained in terms of mist fineness, makeup protection effect, non-sticky feel, and clogging prevention effect. Furthermore, even when a higher viscosity non-volatile oil was further blended into the low viscosity non-volatile oil, excellent results were still obtained in terms of mist fineness, makeup protection effect, non-sticky feel, and clogging prevention effect of the spray nozzle or spray tip. This is likely because the overall kinematic viscosity of the combined non-volatile oils was significantly reduced to below 300 mm. 2 / s or approximately 100mm 2 / s or less.

[0233] In summary, the protective composition of this technology, containing component (A) an oleophilic resin (film-forming resin), component (B) ethanol, component (C) a metal salt, and component (D) a low-viscosity non-volatile oil, exhibits excellent results in terms of mist fineness, makeup protection effect, non-sticky feel, and anti-clogging effect on the spray nozzle or spray mouthpiece. Furthermore, by further containing water and / or volatile oil, very excellent results are achieved in terms of mist fineness, makeup protection effect, non-sticky feel, and anti-clogging effect on the spray nozzle or spray mouthpiece.
