Description

[Technical field]

[0001] The present invention relates to a sunscreen cosmetic composition, more specifically to a sunscreen cosmetic composition that is excellent in usability and causes little harm to the skin, and that achieves high UV protection without incorporating a large amount of UV protection agent by blending silica having a specific particle size with a powder having a specific particle size and made of a specific material. [Background technology]

[0002] Protecting the skin from the harmful effects of ultraviolet rays is one of the important issues in skin care and body care, and various UV care cosmetics have been developed to minimize the adverse effects of ultraviolet rays on the skin. Sunscreen cosmetics, which are one type of UV care cosmetics, are cosmetics intended to protect the skin from the harmful effects of ultraviolet rays by covering the skin with a coating film containing ultraviolet absorbing agents and ultraviolet scattering agents, thereby absorbing or scattering UVA and UVB rays and reducing the amount of ultraviolet rays that reach the skin (Non-Patent Document 1).

[0003] UV absorbers are incorporated into many sunscreen cosmetics because they provide high UV protection, are compatible with the skin, and are resistant to sweat and water. However, some UV absorbers generate heat or undergo chemical reactions when absorbing UV rays, causing redness, itching, and even allergies on the skin. For example, ethylhexyl methoxycinnamate (octyl methoxycinnamate) has been widely used in sunscreen cosmetics as a representative UV absorber that absorbs UVB, but it can be a burden for users with sensitive skin. Patent Document 1 proposes incorporating polypropylene glycol dimethyl ether into a skin topical agent to reduce the irritation caused by ethylhexyl methoxycinnamate.

[0004] In addition, many UV absorbents are solid at room temperature, and a certain amount of oil is required to dissolve them stably in cosmetics without precipitating. Therefore, in order to incorporate a high amount of UV absorbent, the amount of oil must also be increased, which can cause stickiness due to the oil and impair the feel of use. Therefore, instead of incorporating a high amount of oil-soluble UV absorbent, a water-soluble UV absorbent may be incorporated. However, in general, water-soluble UV absorbents tend to have inferior UV protection power compared to oil-soluble ones, and it is difficult to achieve sufficient UV protection power even if a water-soluble UV absorbent is incorporated in a high amount. In addition, when a water-soluble UV absorbent is incorporated, the stability of the cosmetic may be reduced due to the influence of the salt (neutralizing salt) incorporated therewith.

[0005] In view of these circumstances, it has been proposed to use ultraviolet scattering agents that are relatively less irritating to the skin, instead of ultraviolet absorbers, and cosmetics that claim to be "no ultraviolet absorbers" or "non-chemical" have been put on the market. For example, Patent Document 2 discloses a sunscreen cosmetic that contains hydrophobized zinc oxide and / or hydrophobized titanium oxide as an ultraviolet scattering agent, does not contain an organic ultraviolet absorber, and has excellent ultraviolet protection effect, emulsion stability, and usability. Patent Document 3 also proposes blending multiple powder components that have ultraviolet scattering properties, without containing ultraviolet absorbers such as ethylhexyl methoxycinnamate, which causes irritation when it comes into contact with the eyes.

[0006] However, in order to obtain a high UV protection effect using only UV scattering agents, it is necessary to incorporate a large amount of the agent, which may result in an unnatural white appearance (white cast) when applied to the skin, or poor usability in terms of spreadability and compatibility with the skin.

[0008] [Non-Patent Document 1] "New Cosmetics Science", 2nd edition, edited by Takeo Mitsui, published by Nanzando in 2001, pp. 497-504 Summary of the Invention [Problem to be solved by the invention]

[0009] The present invention has been made in view of the above-mentioned circumstances, and has an object to provide a sunscreen cosmetic which can achieve high UV protection power even with the use of a small amount of a UV protection agent by improving the UV protection power of a UV protection agent, and which is easy to use and places little strain on the skin. [Means for solving the problem]

[0010] As a result of intensive research by the present inventors to solve the above problems, they discovered that by blending silica having a specified particle size and powder having a specified particle size and made of a specified material in a sunscreen cosmetic composition containing an ultraviolet protection agent, a uniform coating film is formed on the skin, thereby improving the ultraviolet protection ability and, moreover, achieving excellent usability, which led to the completion of the present invention.

[0011] That is, the present invention provides the following components (A) to (C): (A) UV protection agent, (B) Silica having a particle size of 0.3 to 1 μm, and (C) a powder having a particle size of 1 to 30 μm; Including, The gist of the present invention is a sunscreen cosmetic, wherein the powder (C) is one or more selected from the group consisting of silica, aluminum starch octenyl succinate, cellulose or its derivatives, wax, mica, sericite, and biodegradable resins. Effect of the Invention

[0012] By adopting the above-mentioned configuration, the present invention can improve the ultraviolet protection ability of an ultraviolet protection agent and can realize a sunscreen cosmetic composition that is also easy to use. In addition, the amount of ultraviolet absorbing agents, which can be harmful to the skin, can be kept to a minimum, making it possible to provide a sunscreen cosmetic that is highly safe. Furthermore, since a high level of ultraviolet protection effect is achieved without a large amount of ultraviolet scattering agents, the white cast and poor skin compatibility that are characteristic of ultraviolet scattering agents are unlikely to occur.

[0029] An example of a 4,4-diarylbutadiene derivative is 1,1-dicarboxy(2,2'-dimethylpropyl)-4,4-diphenylbutadiene.

[0030] Particularly preferred examples of the ultraviolet absorbing agent include octocrylene, octyl salicylate, and homosalate, and it is preferable to include at least one of these.

[0031] The ultraviolet scattering agent is not particularly limited, but examples thereof include fine particle metal oxides such as zinc oxide, titanium oxide, iron oxide, cerium oxide, and tungsten oxide.

[0032] The ultraviolet scattering agent may be untreated or may be treated with various hydrophobic surface treatments, but preferably used is treated with hydrophobic surface treatments. Surface treatment agents that can be used include those commonly used in the field of cosmetics, such as dimethicone, silicones such as alkyl-modified silicones, alkoxysilanes such as octyltriethoxysilane, dextrin fatty acid esters such as dextrin palmitate, and fatty acids such as stearic acid.

[0033] The ultraviolet protection agent (A) in the present invention includes an embodiment consisting of only an ultraviolet absorbing agent, an embodiment consisting of only an ultraviolet scattering agent, and an embodiment containing both an ultraviolet absorbing agent and an ultraviolet scattering agent.

[0034] The blending amount of (A) ultraviolet protection agent is preferably 5 to 40% by mass, more preferably 10 to 30% by mass, and even more preferably 10 to 20% by mass, based on the total amount of the sunscreen cosmetic. If the blending amount of (A) ultraviolet protection agent is less than 5% by mass, it is difficult to obtain a sufficient ultraviolet protection effect, and even if it is blended in more than 40% by mass, an increase in ultraviolet protection effect commensurate with the blending amount cannot be expected, and instead stability and usability are deteriorated, which is not preferable.

[0035] <(B) Silica> The silica (B) blended in the sunscreen cosmetic of the present invention is silica having a particle size of 0.3 to 1 μm, preferably 0.4 to 1 μm, and more preferably 0.5 to 1 μm. As long as the particle size is within this range, silica used in ordinary cosmetics can be used without any particular restrictions. In this specification, the "particle size" is a value measured by a particle size distribution measuring device using a laser diffraction / scattering method.

[0036] The shape of the (B) silica is preferably spherical, more preferably true spherical, in that it provides a smooth and pleasant feel to the touch. In the present invention, true spherical means that it is an approximately perfect circle when projected from any direction, and the minimum particle size is 80% or more, more preferably 90% or more, of the maximum particle size.

[0037] In addition, (B) silica that has been subjected to hydrophobic treatment can also be used. The hydrophobic treatment agent is not particularly limited, but can be prepared by covering with, for example, an organosilane compound, a silicone compound, a fluorine compound, etc. More specifically, dimethylsilylated silica, trimethylsilylated silica, octylsilylated silica, silicone oil-treated silica, methylpolysiloxane-treated silica, metal soap-treated silica, amino acid-treated silica, higher alcohol-treated silica, mineral wax-treated silica, etc. can be mentioned.

[0038] As the silica (B), a commercially available product can be used, and for example, "COSMO 55" (JGC Catalysts and Chemicals Co., Ltd.) can be suitably used.

[0039] The blending amount of (B) silica is preferably 0.2 to 2 mass% based on the total amount of the sunscreen cosmetic, more preferably 0.2 to 1.5 mass%, and even more preferably 0.2 to 1 mass%. If the blending amount of (B) silica is less than 0.2 mass%, it becomes difficult to obtain a sufficient improvement in UV protection power, and if it is blended in more than 2 mass%, usability tends to deteriorate.

[0040] <(C) Powder> The powder (C) blended in the sunscreen cosmetic of the present invention is one or more powders selected from the group consisting of silica, aluminum starch octenyl succinate, cellulose or its derivatives, wax, mica, sericite, and biodegradable resins, which are usually blended in cosmetics to improve usability. These powders may also be used whose surfaces have been subjected to a hydrophobic treatment.

[0041] The powder (C) has a particle size of 1 to 30 μm, preferably 4 to 20 μm, and more preferably 4 to 10 μm. If the particle size is outside this range, sufficient usability improvement effect may not be obtained. The shape of the powder (C) is preferably spherical, and more preferably true spherical, in the same way as the silica (B), in that it provides a smooth and pleasant feel to the touch.

[0042] (C) Silica that can be used as powder differs from (B) silica in that it has a larger particle size. Commercially available products include "Sunsphere L-51" (AGC Si-Tech Co., Ltd.). Aluminum starch octenylsuccinate is an aluminum salt of the reaction product of octenylsuccinic anhydride and starch. Because it has oil absorbing properties, it is sometimes used in cosmetics to improve stickiness. Commercially available products such as "TAPIOCA SDS" (Bo-kwang Co., Ltd.) can be used.

[0043] The cellulose or its derivatives include, in addition to cellulose, those in which the hydroxyl groups in the cellulose molecule have been substituted, and examples thereof include spherical cellulose, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, and methylhydroxypropyl cellulose.

[0044] The wax is a wax having a melting point of 80° C. or higher that has been powdered by pulverization or the like, and is not particularly limited as long as it can be incorporated into cosmetics. Such waxes can be obtained by powdering waxes such as carnauba wax, synthetic hydrocarbon wax, polyethylene wax, ethylene propylene copolymer wax, and Fischer-Tropsch wax by mechanically pulverizing the wax using a jetmizer or the like, or by dissolving the wax in a volatile solvent and spray drying the wax. Commercially available products that can be used include PRESS-AID-SP and PRESS-AID-XP (both manufactured by Presperse).

[0045] Both mica and sericite are layered silicates and are widely used in cosmetics as extender pigments. Examples of biodegradable resins include polyester resins such as polylactic acid, polyesteramide resins, polyestercarbonate resins, polysaccharides, polypeptides, lignin, and derivatives thereof.

[0046] The blending amount of (C) powder is preferably 0.5 to 20 mass% based on the total amount of the sunscreen cosmetic, more preferably 1 to 10 mass%, and even more preferably 1 to 5 mass%. If the blending amount of (C) powder is outside the above range, mainly usability tends to deteriorate.

[0047] <Mixing ratio of (B) silica and (C) powder by mass> The blending mass ratio of (B) silica and (C) powder is not particularly limited, but it is preferable that (B)<(C), that is, the blending amount of (C) powder is greater than the blending amount of (B) silica. By blending the (C) powder in a larger amount than the (B) silica, there is a tendency to obtain particularly excellent effects in both the improvement of UV protection power and usability.

[0048] The sunscreen cosmetic of the present invention may further contain a powder of silica having a particle size different from that of the (B) silica and (C) powder, or a powder of aluminum starch octenyl succinate, etc., so long as the effect of the present invention is not impaired.

[0049] <Optional ingredients> In addition to the above components (A) to (C), the sunscreen cosmetic of the present invention may contain components that are usually used in cosmetics, provided that the effects of the present invention are not impaired. For example, oily components, aqueous components, alcohols, moisturizers, thickeners, surfactants, film-forming agents, powder components, UV scattering agents, stabilizers, chelating agents, preservatives, fragrances, etc. may be appropriately blended as necessary.

[0050] The sunscreen cosmetic of the present invention can be provided in any form, such as an aqueous cosmetic, an oil-based cosmetic, an oil-in-water emulsion cosmetic, a water-in-oil emulsion cosmetic, etc. Specific dosage forms include a skin lotion, an emulsion, a cream, a lotion, a spray, etc., and each dosage form can be produced by a conventional method suitable for the dosage form. EXAMPLES

[0051] The present invention will be described in more detail below with reference to examples, but the present invention is not limited thereto. The blending amounts are expressed in mass% based on the total amount of the sunscreen cosmetic unless otherwise specified. Before describing each example in detail, the evaluation methods used will be described.

[0052] <Improvement rate of UV protection> On a measurement plate (S plate) (5 x 5 cm V-groove PMMA (polymethyl methacrylate) plate, SPFMASTER-PA01), 2 mg / cm of each cosmetic material (sample) was applied. 2 The absorbance of the coating film formed was measured using a Hitachi U-3500 model recording spectrophotometer, after which the plate without coating was used as a control and the absorbance (Abs) was calculated using the following formula. The measured values ​​from 280 nm to 400 nm were integrated to obtain the integrated absorbance value. Abs = -log(T / To) T: transmittance of sample, To: transmittance without coating

[0053] From the obtained integrated absorbance value of the sample, the improvement rate of the UV protection power was calculated using the following formula, based on a control sample (Comparative Example 1) that did not contain (B) silica and (C) powder. [Improvement rate of UV protection power (%)] = [integrated absorbance value of sample] / [integrated absorbance value of Comparative Example 1] × 100 The calculated improvement rate of the UV protection power was judged according to the following evaluation criteria. "Evaluation Criteria" A: UV protection power improved by 110% or more B: UV protection improvement rate is 105% or more but less than 110% C: UV protection improvement rate is less than 105%

[0054] <Usability> Each sample of the Examples and Comparative Examples was actually used by a panel of 10 experts, who evaluated its usability (non-stickiness, freshness). Each panelist was asked to perform a sensory evaluation on a 5-point scale according to the following evaluation criteria, and the total score was used to judge the product according to the following evaluation criteria. "Evaluation criteria" 5: Excellent 4: Excellent 3: Normal 2: Inferior 1: Very poor "Evaluation Criteria" A: Total score is 40 or more B: Total score is 30-39 points C: Total score is 29 or less

[0055] <Examples 1 to 2 and Comparative Examples 1 to 9> Water-in-oil sunscreen cosmetics were prepared having the compositions shown in the following Table 1. The improvement rate of UV protection power and usability were evaluated according to the above-mentioned evaluation methods.

[0056] [Table 1]

[0057] As shown in Table 1 above, when both silica corresponding to component (B) and silica corresponding to component (C) were blended, a clear improvement in UV protection power was confirmed compared to when they were not blended (Comparative Example 1), and excellent results were also obtained in terms of usability (Examples 1 and 2). On the other hand, when only silica corresponding to component (B) was blended, the UV protection power was improved but the usability was significantly poor (Comparative Example 2).When only silica corresponding to component (C) was blended, the usability was excellent but no improvement in the UV protection power was observed (Comparative Example 3).

[0058] Furthermore, even when silica with a particle size much smaller than that of Comparative Example 2 was blended, an improvement in UV protection power was observed (Comparative Example 4), but even when silica corresponding to component (C) was also blended, it was not possible to simultaneously achieve the improvement in UV protection power and excellent usability (Comparative Example 5).

[0059] Furthermore, when spherical PMMA powder or (vinyl dimethicone / methicone silsesquioxane) crosspolymer powder, which are commonly used in ordinary cosmetics as powders to improve usability, were blended, excellent results were indeed shown in terms of usability (Comparative Examples 6 and 8), but even when these were combined with silica, which corresponds to component (B), the UV protection power could not be sufficiently improved (Comparative Examples 7 and 9).

[0060] <Examples 3 to 6 and Comparative Examples 10 to 11> Water-in-oil sunscreen cosmetics having the compositions shown in Table 2 below were prepared, and the improvement rate of UV protection power and usability were evaluated according to the above-mentioned evaluation methods. However, in the evaluation of the improvement rate of UV protection power, Comparative Example 10 was used as a control sample instead of Comparative Example 1.

[0061] [Table 2]

[0062] As shown in Table 2 above, when silica corresponding to component (B) and silica or aluminum starch octenyl succinate corresponding to component (C) were blended, a clear improvement in UV protection power was confirmed compared to when these were not blended (Comparative Example 10), and excellent results were also obtained in terms of usability (Examples 3 to 6). On the other hand, when only starch aluminum octenyl succinate, which corresponds to component (C), was blended, although the usability was excellent, the ultraviolet protection power could not be sufficiently improved (Comparative Example 11).
