Embodiments for Carrying Out the Invention

[0012] Hereinafter, preferred embodiments for carrying out the present technology will be described. The embodiments described below show an example of typical embodiments of the present technology, and the scope of the present technology is not construed narrowly thereby. In the present specification, percentages are expressed by mass (mass / mass%) unless otherwise specified. Also, the upper limit value (hereinafter) and the lower limit value (above) of each numerical range (~) can be arbitrarily combined as desired.

[0013] 1. Regarding the present technology

[0014] The inventor has intensively studied a multi-layer protective composition that is expected to have a makeup protective effect and contains an oily resin. Since the present technology is a multi-layer composition, the appearance state of the composition is different from that of cosmetics such as Patent Documents 1 to 3, and the concept or direction of the combination of the composition is naturally greatly different.

[0015] The inventor has studied a multi-layer makeup protective cosmetic using an oil-soluble film-forming silicone resin. A multi-layer composition obtained by further blending 40 to 95% of water and a volatile oil agent with the oil-soluble film-forming silicone resin has a good fineness of mist and makeup protective effect, but has a sticky feeling after application. When continuously using a spray-type container, the lipophilic resin precipitates near the discharge port, causing clogging of the injection port or injection nozzle. The inventor considered that although the film-forming speed is good when using a volatile oil agent in the composition, on the other hand, it causes clogging of the injection port or injection nozzle over time. And the inventor found that even a composition containing a lipophilic resin, ethanol, water and a volatile oil agent, further blended with ethanol as shown in Reference Example 1 of [Examples] below, still causes clogging of the injection port or injection nozzle over time.

[0016] Therefore, the main object of the present technology is to provide a multi-layer makeup protective cosmetic that has a good film-forming speed when used, has a good feeling of use without stickiness, and can prevent clogging of the injection port or injection nozzle over time.

[0017] As a result of intensive studies, the present inventor has found that by using a composition containing a lipophilic resin, ethanol, a metal salt, and a low-viscosity non-volatile oil agent, it is possible to provide a multi-layer makeup protective cosmetic that has a good feel without stickiness and can prevent clogging of the injection port or injection nozzle over time (Examples 1 to 28). Moreover, this technology also has the excellent advantage that even when a volatile oil agent is not used, the film-forming speed of the lipophilic resin can be made good (Examples 1 to 4, etc.). Furthermore, even when this technology further contains a non-volatile oil agent with medium to high viscosity different from the low-viscosity non-volatile oil agent, it has an excellent advantage that the film-forming speed during use is good, it has an excellent feel without stickiness, and it can prevent clogging of the injection port or injection nozzle over time, and it can also provide a multi-layer makeup protective cosmetic (Examples 25 and 26). And even when this technology further contains a volatile oil agent, it has an excellent advantage that it can provide a multi-layer makeup protective cosmetic that has an excellent feel without stickiness, can prevent clogging of the injection port or injection nozzle over time, and has a good film-forming speed during use (Examples 27 and 28). Incidentally, the composition of this technology may be used as a cosmetic or a topical skin preparation, and the components, configurations, contents, etc. described in detail below may be appropriately adopted.

[0018] Furthermore, the present technology can provide a multi-layered cosmetic having a makeup protection effect, and the cosmetic may be a topical skin preparation or composition. And the present technology also has the advantage that it can be used on makeup as the user usually does, on the skin before applying makeup, or during makeup application. It can prevent or suppress the breakdown of ordinary makeup and has a makeup protection effect. Also, it has the effect of preventing secondary adhesion to clothing and masks. Furthermore, even by mixing and applying it with cosmetics such as foundation, blush, and eyeshadow, or sprinkling it on a cosmetic applicator such as a brush or sponge and then applying the cosmetic, the breakdown of ordinary makeup can be prevented or suppressed, and it has a makeup protection effect. Therefore, the present technology can meet the demands of consumers who want to improve the makeup hold of individual and specific makeup applied to the skin or face using their own cosmetics. Also, the present technology can be appropriately applied or used according to the makeup situation, method, touch-up (makeup retouch), procedure, technique, or technology, etc., for the desired makeup, when applying the desired makeup, or after makeup application. Incidentally, the present technology may obtain a makeup protection effect by directly spraying it on clothing, masks, etc. that touch the skin during makeup application to prevent secondary adhesion of makeup to clothing, masks, etc. Although it can take various usage forms, from the viewpoint of the makeup protection effect, it is preferably used on makeup, on the skin before applying makeup, or during makeup application.

[0019] In addition, the present inventor has obtained the finding that by using a lipophilic resin, it is easy to form a film having an excellent barrier effect against particles in the air polluted by, for example, pollen, PM2.5, and yellow sand (Patent Document 4: WO2020 / 175398). As shown in the following [Examples], since using a multilayer composition containing at least a lipophilic resin for makeup prevents makeup from collapsing for a long time, this technology can be used on the skin before applying makeup or after applying it, and in addition to protecting makeup, it can also be used as a composition for protecting the skin against air pollution, preventing pollen, countering PM2.5, and countering atmospheric particles. Further, this technology also has the advantage that various particles are less likely to adhere to the surface of the skin or the surface of makeup using the skin protection composition according to this technology.

[0020] Hereinafter, this technology will be described in detail.

[0021] 2. Multilayer makeup protective cosmetic according to this embodiment This embodiment preferably provides a multilayer makeup protective cosmetic containing component (A) a lipophilic resin, component (B) ethanol, component (C) a metal salt, and component (D) a low-viscosity non-volatile oil agent, and the low viscosity of the component (D) preferably has a kinematic viscosity at 25°C of less than 300 mm 2 / s. Thereby, it is possible to exhibit a good feeling of use without stickiness and an effect of preventing clogging of the injection port or injection nozzle over time. Furthermore, there is also an advantage that the film-forming speed at the time of use is good. In addition, the makeup protective cosmetic can be used as a composition for protecting the skin or a cosmetic for protecting the skin instead of protecting makeup. Further, the makeup protective cosmetic may be used for protective measures against or prevention of adhesion of particles in the air such as PM2.5 and pollen.

[0022] This embodiment is preferably used by spraying on the face. Since this embodiment can spray a fine mist, it has the advantage of easily forming a uniform film on the face or makeup, which is also good from the viewpoint of makeup protection.

[0023] In this embodiment, it is preferable that the component (A) lipophilic resin is a silicone resin. Also, in this embodiment, it is preferable that the component (C) is an inorganic acid metal salt which is a salt of an alkali metal or an alkaline earth metal. Also, in this embodiment, it is preferable that the component (D) is one or more selected from the group consisting of silicone oil, ester oil, and hydrocarbon oil. Also, in this embodiment, it is preferable to further contain water and / or a volatile oil agent. Also, in this embodiment, it is preferable that the content mass ratio (B) / (A) of the component (B) to the component (A) is 1 to 200. Also, in this embodiment, it is preferable that the content mass ratio (C) / (A) of the component (C) to the component (A) is 0.02 to 20. In this embodiment, it is preferable that the content mass ratio (A) / (D) of the component (A) to the component (D) is 0.01 to 6. Also, in this embodiment, it is preferable to further contain a volatile oil agent. Also, in this embodiment, a medium- to high-viscosity non-volatile oil agent may be further contained.

[0024] Hereinafter, the multi-layer makeup protective cosmetic according to this embodiment will be described in detail. Note that each component used in this embodiment is not particularly limited as long as it can be normally used in cosmetics or external skin preparations.

[0025] <2-1. Lipophilic Resin> 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 be normally used in cosmetics or external skin preparations, but has the property of being soluble in an oil agent or swelling and uniformly dispersing in an oil agent, and a lipophilic resin that can be used in normal cosmetics or external skin applications is preferable. The lipophilic resin is preferable from the viewpoint of the makeup protection effect. The lipophilic resin is more preferably an oil-soluble film-forming lipophilic resin, and the oil-soluble film-forming lipophilic resin is soluble in an oil agent such as a volatile oil and can form a film, and a resin that can be used in normal cosmetics or external skin preparations is even more preferable.

[0026] In this specification, the "resin" in "lipophilic resin" means a substance that includes an adhesive substance obtained from tree bark and a polymer compound, and includes those that can be usually used in cosmetics or external skin preparations regardless of their origin, such as natural resins, semi-synthetic resins, and synthetic resins. The "lipophilicity" of the "lipophilic resin" in this specification refers to the property of being soluble in an oil agent or swelling and uniformly dispersing in an oil agent.

[0027] Component (A) The lipophilic resin is not particularly limited. For example, silicone resins such as polymethylsilsesquioxane, polypropylsilsesquioxane, trimethylsiloxysilicic acid, trifluoroalkyl dimethyl trimethylsiloxysilicic acid, (trimethylsiloxysilicic acid / dimethiconol) copolymer, (dimethylsilicone / vinyltrimethylsiloxysilicic acid) copolymer, (dimethylsilicone / vinyldimethylsilicone) copolymer, (vinyldimethyl / trimethylsiloxysilicic acid / dimethylsilicone) copolymer, (vinyldimethyl / trimethylsiloxysilicic acid stearyldimethylsilicone) copolymer; (meth)acrylic resins such as (styrene / acrylates) copolymer, (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer; (meth)acrylic-silicone graft polymers such as (acrylates / dimethylsilicone) copolymer, (acrylates / polytrimethylsiloxysilicate methacrylate) copolymer; dextrin fatty acid esters such as dextrin isostearate; α-olefin / vinylpyrrolidone copolymers such as (VP / eicosene) copolymer; silicone-modified polysaccharide compounds such as tri(trimethylsiloxy)silylpropylcarbamic acid pullulan; pullulan fatty acid esters such as myristoylated pullulan, palmitoylated pullulan; rosin acid resins such as rosin-modified phenol resin, rosin ester; candelilla resin; vinyl acetate resin; saturated or unsaturated hydrocarbon resins such as polybutene resin, polyisoprene resin, and hydrogenated resins thereof; polyurethane resin, etc. By combining these components (A) with the components described below, the film-forming speed, good usability without stickiness, and prevention of clogging of the injection port or injection nozzle over time are likely to be improved. One or more of these components (A) can be selected, and it is preferable to combine a plurality of them. Note that "(meth)acrylic acid" means "acrylic acid" and / or "methacrylic acid", and "(meth)acryl" means acrylic and / or methacryl.

[0028] As the lipophilic resin in component (A), from the viewpoints of makeup protection effect and fineness of mist during use, one or more selected from the group consisting of silicone resins, (meth)acrylic resins, (meth)acrylic-silicone graft polymers, and dextrin fatty acid esters are preferable, one or more selected from the group consisting of silicone resins, (meth)acrylic resins, and (meth)acrylic-silicone graft polymers are more preferable, and among them, silicone resins are preferable. In this embodiment, one selected from the examples of the lipophilic resin may be used alone, but using two or more in combination is more preferable because it is more excellent in makeup protection effect and fineness of mist during use. Further, in order to make the non-greasy feeling of use and the makeup protection effect better, two or more selected from the group consisting of silicone resins such as polymethylsilsesquioxane described above may be used in combination. For example, polymethylsilsesquioxane and trimethylsiloxysilicic acid may be used in combination.

[0029] Among the lipophilic resins of component (A), one or more selected from the group consisting of polymethylsilsesquioxane, trimethylsiloxysilicic acid, (acrylates / dimethicone) copolymer, trifluoroalkyl dimethyl trimethylsiloxysilicic acid, (dimethicone / vinyltrimethylsiloxysilicic acid) cross-polymer, (trimethylsiloxysilicic acid / dimethiconol) cross-polymer, (dimethicone / vinyldimethicone) cross-polymer, (styrene / acrylates) copolymer, (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer, and dextrin isostearate are preferred. Further, one or more selected from the group consisting of (dimethicone / vinyldimethicone) cross-polymer, polymethylsilsesquioxane, trimethylsiloxysilicic acid, (acrylates / dimethicone) copolymer, trifluoroalkyl dimethyl trimethylsiloxysilicic acid, (dimethicone / vinyltrimethylsiloxysilicic acid) cross-polymer, (trimethylsiloxysilicic acid / dimethiconol) cross-polymer, (styrene / acrylates) copolymer, (cyclohexyl methacrylate / ethylhexyl methacrylate) copolymer, and dextrin isostearate are more preferred. Further, one or more selected from the group consisting of (dimethicone / vinyldimethicone) cross-polymer, polymethylsilsesquioxane, trimethylsiloxysilicic acid, (acrylates / dimethicone) copolymer, trifluoroalkyl dimethyl trimethylsiloxysilicic acid, (dimethicone / vinyltrimethylsiloxysilicic acid) cross-polymer, and (trimethylsiloxysilicic acid / dimethiconol) cross-polymer are even more preferred. Thereby, the makeup protection effect and the fineness of the mist during use are better, the film-forming speed is good, and it has a good feeling of use without stickiness, and it is also easy to obtain an effect of preventing clogging of the injection port or injection nozzle over time. It is more preferable that the lipophilic resin of component (A) contains at least trimethylsiloxysilicic acid. At this time, trimethylsiloxysilicic acid may be combined with other lipophilic resins or silicone resins different from this.

[0030] Furthermore, among the component (A) lipophilic resins, from the viewpoint of the makeup protection effect, a film-forming lipophilic resin is preferred. Film formation refers to a process in which a resin solution obtained by dissolving a lipophilic resin in a volatile oil agent is uniformly applied to a glass plate at a certain thickness (for example, 400 μm, etc.), and after the volatile oil agent is volatilized, a film is formed.

[0031] As examples of the film-forming lipophilic resin used in this embodiment, among the examples of the lipophilic resins and compounds described in the above-mentioned "component (A) lipophilic resin", resins capable of forming a film can be appropriately employed. Among these, film-forming silicone resins, film-forming (meth)acrylic acid resins, film-forming (meth)acrylic-silicone graft polymers, and film-forming dextrin fatty acid esters are preferred, and further, film-forming silicone resins, film-forming (meth)acrylic acid resins, and film-forming (meth)acrylic-silicone graft polymers are more preferred. Among these, from the viewpoint of being able to form a film that is more resistant to sweat and sebum and less sticky, a film-forming silicone resin is preferred. One or more selected from these can be used.

[0032] In this embodiment, a commercially available product can be used as the component (A). For example, KF7312J (solid content: 50%, solvent: cyclopentasiloxane, manufactured by Shin-Etsu Chemical Co., Ltd.), KF-9021 (solid content: 50%, solvent: cyclopentasiloxane, manufactured by Shin-Etsu Chemical Co., Ltd.), BY11-018 (solid content: 30%, solvent: cyclopentasiloxane, manufactured by Toray Dow Corning Co., Ltd.), KP541 (solid content: 60%, solvent: isopropanol, manufactured by Shin-Etsu Chemical Co., Ltd.), SR-1000 (manufactured by Momentive Performance Materials Japan), KP545 (solid content: 30%, solvent: cyclopentasiloxane, manufactured by Shin-Etsu Chemical Co., Ltd.), KP575 (solid content: 30%, solvent: cyclopentasiloxane, manufactured by Shin-Etsu Chemical Co., Ltd.), BELSIL TMS 803 (manufactured by Asahi Kasei Wacker Silicone Co., Ltd.), BELSIL RG 90 (solid content: 20%, solvent: isododecane, manufactured by Asahi Kasei Wacker Silicone Co., Ltd.), BELSIL RG 100 (solid content: 20%, solvent: decamethylcyclopentasiloxane, manufactured by Asahi Kasei Wacker Silicone Co., Ltd.), DOWSIL FC-5004DM (1.5 cSt) Silicone Resin Gum (solid content: 40%, solvent: dimethicone, manufactured by Toray Dow Corning Co., Ltd.), SILFORM FLEXIBLE RESIN (manufactured by Momentive Performance Materials Japan), XS66-B8226 (solid content: 50%, solvent: cyclopentasiloxane, manufactured by Momentive Performance Materials Japan), Oppanol B-100 (manufactured by BASF), Unifilma HVY (manufactured by Chiba Flour Milling Co., Ltd.), etc. can be mentioned. One or more selected from these can be used.

[0033] The content of the above-mentioned component (A), the lipophilic resin (preferably a film-forming lipophilic resin), is not particularly limited in the total mass of the cosmetic. However, from the perspective of the makeup protection effect, the preferable lower limit is preferably 0.01% or more, more preferably 0.05% or more, still more preferably 0.1% or more, even more preferably 0.5% or more, and even more preferably 1% or more. Also, from the perspective of a non-greasy feeling in use, the preferable upper limit is preferably 15% or less, more preferably 10% or less, still more preferably 8% or less, even more preferably 5% or less. Further, as a preferable numerical range of the content of the above-mentioned component (A), the lipophilic resin, in the total mass of the cosmetic, it is preferably 0.01 to 10%, and more preferably 0.05 to 8%. By setting it within this range, while having a makeup protection effect, a non-greasy feeling in use and an effect of preventing clogging of the injection port or injection nozzle over time are good, and it is also easy to favorably adjust the film-forming speed when used.

[0034] Also, when using a combination of two or more different lipophilic resins, the content of the above-mentioned component (A) described above may be the total content of the component (A). In the case of a combination of two different lipophilic resins, the content mass ratio ((a):(b)) is preferably 10 to 1:1 to 10, more preferably 5 to 1:1 to 5, still more preferably 2 to 1:1 to 2. It is preferable that the above-mentioned (a) is trimethylsiloxysilicic acid, and the above-mentioned (b) is a lipophilic resin other than this or a silicone-based resin different from this.

Also, the content of the silicone-based resin is not particularly limited in the total mass of the composition. However, the preferable lower limit and upper limit of the content of the lipophilic resin described above can be appropriately adopted. As a more preferable numerical range, it is preferably 0.01 to 10%, and more preferably 0.05 to 8%.

[0036] Also, the content of trimethylsiloxysilicic acid and / or polymethylsilsesquioxane is not particularly limited in the total mass of the composition. However, the preferable lower limit and upper limit of the content of the above-mentioned lipophilic resin can be appropriately adopted. As a more preferable numerical range, it is preferably 0.01 to 10%, more preferably 0.05 to 8%. By combining both trimethylsiloxysilicic acid and polymethylsilsesquioxane, a non-greasy feeling of use and a better makeup protection effect can be achieved.

[0037] <2-2. Ethanol> Component (B) ethanol used in this embodiment is not particularly limited as long as it can be normally used in cosmetics or external skin preparations. Ethanol is a solvent soluble in water and a component with volatility at normal temperature (aqueous volatile component). Thereby, a refreshing feeling can be obtained during spray use, and the film-forming speed, non-greasy good feeling of use, and makeup protection effect can be improved.

[0038] The content of component (B) ethanol is not particularly limited. However, in the total mass of the composition (preferably cosmetics), from the viewpoints of non-greasy feeling of use, makeup protection effect, clogging prevention effect, and film-forming speed, 0.1% or more is preferable, 0.5% or more is more preferable, 1% or more is further preferable, 3% or more is more preferable, 5% or more is further preferable.

[0039] Furthermore, with respect to the component (B) relative to the component (A) in the present embodiment, the content mass ratio (B) / (A) in the total mass of the composition (preferably a cosmetic) is not particularly limited. However, as a preferable lower limit value, from the viewpoints of the film-forming speed and the non-greasy feeling in use, it is preferably 0.1 or more, more preferably 0.3 or more, still more preferably 0.5 or more, even more preferably 1 or more, more preferably 1.5 or more, and still more preferably 2 or more. Also, as a preferable upper limit value, from the viewpoint of the clogging prevention effect of the ejection port or the ejection nozzle, it is preferably 400 or less, more preferably 300 or less, still more preferably 200 or less, even more preferably 100 or less, more preferably 50 or less, still more preferably 25 or less, more preferably 10 or less, and still more preferably 5 or less. As a more preferable numerical range, it is preferably 0.1 to 300, and still more preferably 1 to 200. Thereby, it is easy to obtain a better makeup protection effect, a better fineness of the mist, a non-greasy feeling in use, a clogging prevention effect, and a film-forming speed. Note that the component (A) and the component (B) may each be a combination of examples of preferable components, and may be, for example, "ethanol with respect to a lipophilic resin (for example, a silicone-based resin)". Also, the "content mass ratio (B) / (A)" may be the "usage mass ratio (B) / (A)".

[0051] The kinematic viscosity (mm 2 / s) at 25°C in this specification can be measured with the B-type viscometer and its measurement conditions shown below. The kinematic viscosity (mm 2 / s) at 25°C can be calculated by viscosity (mPa·s) / density (g / cm 3 ). The viscosity (mPa·s) in this specification can be determined by measuring the average value for 1 minute at 25°C with a B-type viscometer, rotor No. 2, and 6 rpm.

Note that the component (A) and the component (D) may each be an example of a suitable component, and may be, for example, "a lipophilic resin (such as a silicone-based resin) with respect to a low-viscosity non-volatile oil agent (such as a low-viscosity non-volatile silicone oil)".

Further, this embodiment is excellent in sprayability and film formation even in the multi-layer form, which is due to blending a lipophilic resin and making it a combination of the above components (A) to (D) and water. Further, this embodiment has the advantage that it can be provided as a makeup protective cosmetic free of emulsifier or with reduced emulsifier because the spray particles are fine even without blending an emulsifier.

[0079] Moreover, by combining the above components (A) to (D) in this embodiment, a film having high water resistance and sebum resistance due to the lipophilic resin can be formed on the applied makeup, and it is also possible to have an excellent makeup protective effect in terms of persistence.

[0096] (Manufacturing method) (A) Oil layer: (1) to (10), (17) to (23) are uniformly heated (90 to 95°C) and mixed. (B) Aqueous layer: (11) to (16), (24), (25) are uniformly mixed. (C) A container with a push-type spray nozzle (spray orifice diameter φ0.3 mm: container for non-aerosol) is filled in the order of the aqueous layer of (B) and the oil layer of (A) to obtain a composition (multi-layer makeup protective cosmetic). Incidentally, (1) to (25) can be filled into a container with a spray nozzle in any order, and shaken strongly to obtain a composition (multi-layer makeup protective cosmetic).

[0097] <Regarding the method of using the composition> The composition used in this test is sprayed onto the face with base makeup such as foundation and makeup such as eyeshadow and blush. After shaking the composition used in this test 10 times, it is sprayed 10 times onto the entire face with makeup and applied to the face. When evaluating the composition used in this test, in the following evaluation methods, for example, in the case of the evaluation method of "((b) Non-greasy feeling of use)", the evaluation is carried out 5 minutes (dried) after spraying.

[0098] (Evaluation method) Ten professional cosmetic evaluation panelists sprayed this product 10 times onto the entire face with foundation and eye makeup for each multi-layer makeup protective agent in the test examples, and evaluated " (a) Speed of forming a makeup film", " (b) Non-greasy feeling of use", " (c) Effect of preventing eye clogging", " (d) Makeup protection effect", " (e) Fineness of mist" according to the following evaluation criteria on a 5-point scale and scored. For items (a), (b) and (e), the evaluation was carried out during and immediately after use. For item (d), the subjects were asked to live a normal life after use, and the makeup retention after 8 hours was evaluated. For item (c), the spray amount at the start of use and the spray amount at the end of use were compared. Then, the average score of all panelists was calculated and judged according to the following judgment criteria.

[0099] [Evaluation criteria] (a) Speed of forming a makeup film: Whether the makeup film is formed quickly after application (Score) : (Evaluation result) 4 points: The makeup film is formed within 5 minutes after application 3 points: The makeup film is formed within 5 to 7 minutes after application 2 points: The makeup film is formed within 7 to 9 minutes after application 1 point: The makeup film is formed within 9 to 10 minutes after application 0 points: The cosmetic film is not formed even 10 minutes after application. In addition, after shaking the container with a spray nozzle filled with the composition 10 times, the composition was sprayed 10 times onto a glass plate (5 cm × 5 cm), and the film formation of the composition applied on the glass plate was observed.

[0100] (b) Non-sticky feeling of use: Whether a sticky feeling is felt 5 minutes after application to the skin (Rating): (Evaluation result) 4 points: There is no stickiness at all. 3 points: There is almost no stickiness. 2 points: There is a slight stickiness. 1 point: There is a bit of stickiness. 0 points: There is a very sticky feeling.

[0101] (c) Clogging prevention effect: Stored at 5°C, discharged 5 pushes per day at 5°C, and the average discharge mass of 5 pushes at the end of the 30th day is the following ratio to the average discharge mass of 5 pushes at the start of the test (N = 3 average) (Rating): (Evaluation result) 4 points: 95% or more 3 points: Less than 95% to 80% or more 2 points: Less than 80% to 65% or more 1 point: Less than 65% to 50% or more 0 points: Less than 50%

[0102] (C) Clogging prevention effect: Specifically, the compositions used in the test are filled into three containers with the above spray nozzles respectively, and three containers with spray nozzles filled with the same composition are prepared. These are stored at 5°C for 10 to 12 hours. After storage, for each container, the discharge mass (mg) sprayed into the beaker when pushed 5 times under a 5°C environment is measured. Calculate the total amount when using three containers, and calculate the average discharge mass (mg) at the start of the test (day 1) per container from this total amount. After the start of the test, these three containers are continuously stored at 5°C and pushed out 5 times every day under a 5°C environment. Taking the 30th day as the end day, measure the discharge mass (mg) sprayed into the beaker when pushed out 5 times at the end of the 30th day, and calculate the average discharge mass (mg) at the end of the test (30th day) per container in the same way as at the start of the test (N = 3 average). Then, calculate the ratio of the average discharge mass of 5 pushes at the end of the test to the average discharge mass of 5 pushes at the start of the test (that is, [average discharge mass per container at the end of the test / average discharge mass per container at the start of the test] × 100 (%)), and the score corresponding to the ratio falling within the range of the following evaluation results is the evaluation of the composition used in the test. The less clogging of the injection port or injection nozzle caused by the composition used, the smaller the difference between the discharge mass at the end of the test and the discharge mass at the start of the test, and the closer it is to 100% of the evaluation result.

[0103] (D) Makeup protection effect: Whether the makeup has collapsed 8 hours after application (Score): (Evaluation result) 4 points: No collapse of makeup is observed 8 hours after application 3 points: Almost no collapse of makeup is observed 8 hours after application 2 points: Slight collapse of makeup is observed 8 hours after application 1 point: Collapse of makeup is observed 8 hours after application 0 point: Severe collapse of makeup is observed 8 hours after application

[0104] (F) Fineness of mist: Whether the fineness of the mist is felt during application (Score): (Evaluation result) 4 points: The mist particles are very fine 3 points: The mist particles are moderately fine 2 points: The mist particles are slightly large 1 point: The mist particles are large and form water droplets on the skin 0 point: It does not spray in a mist form

[0105] [Judgment criteria] (Average score of evaluation): (Judgment) 3.5 points or more: ◎ (Excellent) 2.5 points or more and less than 3.5 points: ○ (Good) 1.5 points or more and less than 2.5 points: △ (Slightly poor) Less than 1.5 points: × (Poor)

[0106] The compositions of Examples 1 to 28 and Reference Example 1 were multi-layer makeup protectants divided into two layers, an upper oil layer and a lower water layer. The compositions of Examples 1 to 28 had a viscosity of 1000 mPa·s or less at 25°C. Regarding the viscosity measurement of the compositions, after shaking the compositions 10 times and then allowing them to stand, the viscosity was measured using a B-type viscometer described in "Viscosity (mPa·s) of the compositions of the present embodiment).

[0107] As is clear from the results in Tables 1 to 3, the compositions of the present technology (Examples 1 to 28, Reference Example 1) can spray finely and evenly over the entire face, so they do not damage the applied makeup. Even for ordinary users, there is an advantage that it is easy to form a makeup film with an appropriate film thickness and uniformity over the entire face. In addition, the compositions of the present technology have the advantage of high sebum resistance because no makeup breakdown is observed even after 8 hours of application to the face, and it is considered that they also have a high skin protection effect. Further, these compositions preferably contain a volatile oil agent, and when they contain water, the water content is preferably in the range of about 50 to 85% by mass, and it is considered possible to adjust it to 1 to 95% by mass.

[0108] And the protective compositions of the present technology (Examples 1 to 28) contain component (A) a lipophilic resin (film-forming resin), component (B) ethanol, component (C) a metal salt, and component (D) a low-viscosity non-volatile oil agent, and are excellent in terms of the fineness of the mist during spraying, the makeup protection effect, the speed of film formation, the non-greasy feeling in use, and the clogging prevention effect. Also, the preferred mass ratio of (B) / (A) for use is in the range of 1 to 200, and the more preferred range is considered to be in the range of 2 to 100. Also, the preferred mass ratio of (C) / (A) for use is in the range of 0.1 to 20, and the more preferred range is considered to be in the range of 0.2 to 10. Also, the preferred mass ratio of (A) / (D) for use is 0.01 to 6, and the more preferred range is considered to be in the range of 0.1 to 3.

[0109] Also, in the case of a protective composition containing a hydrophilic resin, a volatile oil agent, and water, the lack of greasiness and the lack of a burden feeling are not preferable (see Patent Document 4), but in the protective composition of Reference Example 1 containing component (C) a metal salt, a non-greasy feeling in use of "◎ (excellent)" was obtained. However, in the protective composition of Reference Example 1, the clogging prevention effect was not exhibited. Also, in the compositions of Comparative Examples 1 to 5, the makeup protection effect was not obtained, and the other evaluations were also not good.

[0110] The protective composition of the present technology (for example, Example 1) is compared with the protective composition of Reference Example 1, and by changing the volatile oil agent to component (D) a low-viscosity non-volatile oil agent, the clogging prevention effect has changed from "× (not acceptable)" to "◎ (excellent)", and has come to exhibit an extremely excellent effect. Furthermore, by including a combination of a low-viscosity non-volatile oil agent and a volatile oil agent, the clogging prevention effect does not decrease, and extremely excellent results are obtained in terms of the fineness of the mist during spraying, the makeup protection effect, the non-greasy feeling in use, and the clogging prevention effect of the injection port or injection nozzle.

[0111] Also, regarding the low viscosity (kinematic viscosity at 25°C) of the non-volatile oil agent, 100 mm 2When the non-volatile oil agent in the following (Example 25) was used, excellent results were obtained in terms of the fineness of the mist during spraying, the makeup protection effect, the non-greasy feeling during use, and the clogging prevention effect. Also, even when a non-volatile oil agent with a higher viscosity than this was further blended with the low-viscosity non-volatile oil agent and used, excellent results were obtained in terms of the fineness of the mist during spraying, the makeup protection effect, the non-greasy feeling during use, and the clogging prevention effect of the injection port or injection nozzle. This is because the kinematic viscosity of the entire non-volatile oil agent combined with multiple components was much lower than 300 mm 2 / s or became about 100 mm 2 / s or less.

[0112] From the above, the protective composition of the present technology contains component (A) lipophilic resin (film-forming resin), component (B) ethanol, component (C) metal salt, and component (D) low-viscosity non-volatile oil agent, and was excellent in terms of the fineness of the mist during spraying, the makeup protection effect, the non-greasy feeling during use, and the clogging prevention effect of the injection port or injection nozzle. Furthermore, by further containing water and / or volatile oil agent, it was possible to obtain a very excellent product in terms of the fineness of the mist during spraying, the makeup protection effect, the non-greasy feeling during use, and the clogging prevention effect of the injection port or injection nozzle.
