Description

Spray-type cosmetics

[0001] This invention relates to a spray-type cosmetic.

[0002] Including UV absorbers in cosmetics is an important element in protecting the skin from ultraviolet radiation. While oil-soluble UV absorbers such as ethylhexyl methoxycinnamate are widely used, the use of water-soluble UV absorbers such as phenylbenzimidazole sulfone has also been considered in recent years. To date, various cosmetic compositions have been proposed that have UV protection effects by using both oil-soluble and water-soluble UV absorbers. These include, for example, a sunscreen composition containing (a) a water-soluble UV absorber, (b) an oil-soluble UV absorber, (c) polyoxyethylene polyoxypropylene decyltetradecyl ether, and (d) water (see, for example, Patent Document 1), and a two-layer cosmetic composition containing a water-soluble UV absorber having a sulfonic acid group, a basic substance, water, and 40 parts by mass or more of polyhydric alcohol per 100 parts by mass of the total amount of the aqueous phase, and a specific amount of oil-soluble UV absorber and liquid oil in the oil phase, with a mass ratio of 2.5:97.5 to 50:50 and a powder content of 5% by mass or less.

[0003] Furthermore, spray-type cosmetics, which are used by spraying them in a mist form, are used in lotions, hair mists, and makeup protectants because the contents can be easily applied to the application area. In recent years, spray-type cosmetics containing UV absorbers have also been proposed. For example, a two-layer type sunscreen cosmetic containing an organic UV absorber, a volatile silicone oil, a lipophilic powder with an average particle size of 5.0 to 20 μm, and polyvinylpyrrolidone has been proposed (see, for example, Patent Document 3), and a mist-type sunscreen cosmetic characterized by containing specific amounts of a UV absorber, a nonpolar oil, a monoester oil, a diester oil, and a film-forming resin with a silicone chain as its main skeleton has been proposed (see, for example, Patent Document 4).

[0004] Japanese Patent Publication No. 2019-108317, Japanese Patent Publication No. 2019-112451, Japanese Patent Publication No. 2023-085020, Japanese Patent Publication No. 2022-153914

[0005] However, spray-type cosmetics that do not contain water or ethanol, or have a high proportion of oil, have the problem of being sticky. In particular, for cosmetics that require reapplication (spraying) as needed to maintain UV protection, non-sticky usability is extremely important. Furthermore, in spray-type cosmetics, it is very important to continuously dispense the contents uniformly from the start to the end of use in order to exhibit excellent UV protection.

[0006] Specifically, the technology disclosed in Patent Document 1, while excellent in terms of stability over time, sometimes lacked sufficient non-stickiness due to the high amount of surfactant in the total composition. Furthermore, spray application was not considered. The technology disclosed in Patent Document 2, while excellent in terms of UV protection, sometimes lacked sufficient uniform discharge during use and non-stickiness. Furthermore, spray application was not considered. The technology disclosed in Patent Document 3, sometimes lacked sufficient UV protection and non-stickiness. Furthermore, uniform discharge over time was not considered. The technology disclosed in Patent Document 4, while excellent in terms of UV protection, sometimes lacked sufficient non-stickiness. Furthermore, uniform discharge over time under high-temperature conditions was not considered.

[0007] Therefore, the main objective of the present invention is to provide a spray-type cosmetic that is excellent in terms of UV protection effect, uniform dispensing during use, and non-stickiness.

[0008] The inventors diligently studied spray-type cosmetics that are easy to reapply in order to maintain their UV protection effect. However, they found that the non-uniformity of the contents during spraying (for example, variations in the average particle size of emulsion droplets in an emulsified state) resulted in variations in the UV protection effect on the applied surface. Furthermore, they found that the non-uniform discharge of the contents occurred during the use of the spray-type cosmetic (from the start to the end of use) (for example, in an emulsified state, the phase separation of the aqueous phase and the oil phase occurred quickly, making it impossible to maintain the emulsified state, resulting in variations in the discharge amount of the aqueous and oil layers). Therefore, in order to solve the above problems, we conducted further intensive studies and found that by providing a spray-type cosmetic containing 0.005 to 0.25% by mass of a nonionic surfactant with an HLB of 12 or higher, a water-soluble ultraviolet absorber, water, a monohydric lower alcohol, an oil-soluble ultraviolet absorber, and a liquid oil, and with the total amount of water and monohydric lower alcohol being 40% by mass or more of the total amount of the cosmetic, it is possible to uniformly dispense the contents from the start to the end of use, and a spray-type cosmetic with excellent ultraviolet protection effect and non-stickiness can be obtained, thus completing the present invention.

By setting the content within this range, superior UV protection effect, uniform dispensing during use, non-stickiness, and makeup breakdown are achieved.

[0047] The ester oil content of component (F) of the present invention is not particularly limited, but as a lower limit, from the viewpoint of UV protection effect, it is preferably 3% or more, more preferably 5% or more, even more preferably 10% or more, and particularly preferably 15% or more in the total amount of cosmetic composition.

This range provides superior UV protection, uniform dispensing during use, non-stickiness, and makeup breakdown prevention.

[0053] In addition to the above-mentioned components (A) to (F), the spray-type cosmetic composition of the present invention may contain components commonly used in cosmetics, quasi-drugs, pharmaceuticals, etc., to the extent that they do not impair the effects of the present invention. That is, the spray-type cosmetic composition of the present invention may contain surfactants, oils, water-soluble polymers, oil-soluble polymers, film-forming agents, resins, polyhydric alcohols, humectants, antibacterial agents, powders, fragrances, deodorants, salts, chelating agents, pH adjusters, cooling agents, plant extracts, vitamins, beauty ingredients, etc., other than the above-mentioned components.

[0054] Examples of polyhydric alcohols include glycols such as propylene glycol, 1,3-propanediol, 1,3-butylene glycol, dipropylene glycol, and polyethylene glycol; glycerols such as glycerin, diglycerin, and polyglycerin; and sugar alcohols such as sorbitol, maltitol, and glucose.

[0055] <Atomized Cosmetic Composition> The state of the atomized cosmetic composition of the present invention is not particularly limited, but it is preferable that it separates into layers when left to stand, and it is more preferable that it separates into two layers. The state of layer separation is not particularly limited, but in the case of a two-layer separation, examples include an aqueous layer and an oil layer, an aqueous layer and an emulsion layer, an oil layer and an emulsion layer, etc. In the present invention, a two-layer separation state of an aqueous layer and an oil layer, or an aqueous layer and an emulsion layer is preferred, and a two-layer separation state of an aqueous layer and an emulsion layer is more preferred. Here, in the present invention, the time required for layer separation to occur when left to stand (standing time) is not particularly limited, but for example, layer separation can be confirmed after 24 hours.

[0056] The spray-type cosmetic composition of the present invention is preferably shaken before use (especially immediately before use). Shaking helps to make the cosmetic composition uniform, allowing it to exhibit effects such as UV protection and uniform dispensing during use more effectively. Furthermore, in the case of a spray-type cosmetic composition that separates into layers when left standing, shaking is preferable because it allows the entire composition to form a uniform dispersion system from the separated state. For example, in the case of a two-layer separation state of an aqueous layer and an emulsion layer, shaking before use allows the emulsion constituting the emulsion layer to disperse into the aqueous layer, resulting in a uniform dispersion system.

[0057] Furthermore, the spray-type cosmetic of the present invention is preferably used by spraying it onto the face. The spray-type cosmetic of the present invention has the advantage of being able to be sprayed in a fine mist, which allows it to be applied evenly to the face or over makeup without causing irritation. This advantage is also favorable from the viewpoint of cosmetics that require reapplication (spraying) as needed to maintain their UV protection effect. In the present invention, it is preferable to use it over makeup, as it is possible to reapply it without disturbing the makeup even when sprayed over makeup. It is even more preferable to spray it onto the face after applying base makeup such as makeup base, foundation, concealer, and face powder, or makeup such as eyebrow pencil, eyeshadow, eyeliner, blush, highlighter, contouring, and lipstick.

[0058] The viscosity of the spray-type cosmetic of the present invention, when used by spraying it in a mist form, is preferably 1000 mPa·s or less, more preferably 500 mPa·s or less, even more preferably 200 mPa·s or less, even more preferably 100 mPa·s or less, and particularly preferably 50 mPa·s or less, measured at 25°C using a B-type viscometer, rotor No. 2, 6 rpm, and an average value over 1 minute. This range ensures excellent fineness of the mist.

[0059] The uses of the spray-type cosmetic composition of the present invention are not particularly limited, but from the viewpoint of excellent usability such as non-stickiness, it can be suitably used as a cosmetic composition for the skin (including the scalp), and furthermore, since it can provide ultraviolet protection, it can be suitably used as a cosmetic composition for sunscreen purposes.

[0060] The method for manufacturing the spray-type cosmetic composition of the present invention is not particularly limited and can be manufactured by known methods. For example, components (A) to (F) and other components as appropriate can be filled into a container (e.g., a non-gas (non-aerosol) container such as a container with a spray nozzle, a spray container, a finger spray container, a mist spray container; an aerosol container, etc.). The components may be mixed before filling, and may be mixed under appropriate heating (e.g., 70 to 90°C). Alternatively, the components used in this embodiment may be filled into multiple containers such as a water layer container, an oil layer container, and a powder container to form a multi-component combination product such as a two-component or three-component type. The combination may be a set or a kit. In the case of a multi-component product, the user can mix the water layer component, oil layer component, powder component, etc. in desired proportions before spraying. Furthermore, the spray-type cosmetic composition of the present invention can be used in aerosol form using a propellant, but it is preferable to be a non-gas type because it can be sprayed in a good mist form without using a propellant. As a non-gas type container, for example, a container with a spray nozzle can be used. As for the nozzle diameter, a spray container with a diameter of approximately φ0.1 to 0.6 mm (preferably φ0.2 to 0.5 mm) can be used.

[0075] As is clear from the results in Tables 1 to 3 above, the spray-type cosmetics (sunscreens) of Examples 1 to 17 of the present invention were superior to Comparative Examples 1 to 10 in terms of UV protection effect, uniform dispensing during use, lack of stickiness, and no makeup breakdown. Furthermore, as shown in Figure 1, in Example 1, no coalescence or separation of droplets was observed up to 5 minutes after dispensing, and no non-uniformity of the contents was observed. After shaking the spray-type cosmetics of Examples 1 to 17 10 times and letting them stand, the viscosity was measured using a B-type viscometer as described in "Viscosity of the Cosmetics of This Embodiment (mPa·s)" above, and the viscosity at 25°C was 1000 mPa·s or less. The viscosity of the spray-type cosmetics from Examples 1 to 17 onward (i.e., Examples 18 and onward, described later) was measured using the same procedure. After use, the spray-type cosmetics of Examples 1 to 17 were allowed to stand, and layer separation was observed, with a two-layer separation state of an aqueous layer and an emulsion layer being observed.

[0076] On the other hand, in Comparative Example 1, which did not contain component (A), and in Comparative Examples 3 to 5, which used a nonionic surfactant with an HLB of less than 12 instead of component (A), satisfactory uniform dispensing during use was not obtained. As shown in Figure 2, in Comparative Example 1, droplet coalescence progressed over time, and non-uniformity of the contents was observed. In Comparative Example 2, in which the content of component (A) exceeded 0.25%, satisfactory non-stickiness was not obtained. In Comparative Example 6, which did not contain component (C), satisfactory uniform dispensing over time, non-stickiness, and no makeup breakdown were not obtained. In Comparative Example 7, which did not contain component (D), satisfactory uniform dispensing over time and non-stickiness were not obtained. In Comparative Example 8, in which the total amount of components (C) and (D) was less than 40% of the total amount of cosmetic, satisfactory uniform dispensing during use, non-stickiness, and no makeup breakdown were not obtained. In Comparative Example 9, which did not contain ingredient (E), satisfactory UV protection was not obtained. In Comparative Example 10, which did not contain ingredient (F), satisfactory UV protection, uniform dispensing during use, and lack of stickiness were not obtained.

[0077] Based on the above, a spray-type cosmetic containing the following components (A) to (F): (A) 0.005 to 0.25% by mass of a nonionic surfactant with an HLB of 12 or higher, (B) a water-soluble ultraviolet absorber, (C) water, (D) a monohydric lower alcohol, (E) an oil-soluble ultraviolet absorber, and (F) a liquid oil, wherein the total amount of component (C) and component (D) is 40% by mass or more of the total amount of the cosmetic, is excellent in terms of ultraviolet protection effect, uniform discharge during use, and non-stickiness. In particular, it was found that it exhibits excellent uniform discharge during use even when stored for a certain period under high temperature conditions.
