Description

本発明は、日焼け止め化粧料に関し、更に詳しくは、高い紫外線防御効果を維持しつつ、べたつき感、きしみ感が軽減された優れた使用感が持続し、耐水性にも優れる日焼け止め化粧料に関する。   The present invention relates to a sunscreen cosmetic, and more particularly, to a sunscreen cosmetic that maintains a high UV protection effect, maintains a feeling of stickiness and a feeling of squeaky, and maintains excellent water resistance. .

従来、日焼け止め化粧料に期待される紫外線防御効果としては、主にサンバーンを起こすと考えられているUV−B領域(290〜320nm)の紫外線に対するものであった。ところが近年UV−A領域(320〜400nm)の紫外線は皮膚を黒化させるのとともに皮膚の深部にまで到達し、皮膚の老化を促進し、皮膚ガンの原因になりうると考えられている。このように、日焼け止め化粧料にはUV−B領域だけでなくUV−A領域にも高い紫外線防御効果が求められている。   Conventionally, the ultraviolet ray protection effect expected for sunscreen cosmetics has been mainly against ultraviolet rays in the UV-B region (290 to 320 nm) that are considered to cause sunburn. However, in recent years, ultraviolet rays in the UV-A region (320 to 400 nm) are considered to darken the skin and reach the deep part of the skin, promote aging of the skin, and cause skin cancer. Thus, sunscreen cosmetics are required to have a high ultraviolet protection effect not only in the UV-B region but also in the UV-A region.

日焼け止め化粧料には、ベンゾフェノン系化合物、パラアミノ安息香酸化合物、ケイ皮酸系化合物等の紫外線吸収剤や、酸化チタン、微粒子酸化チタン、酸化亜鉛、微粒子酸化亜鉛等の紫外線散乱剤が配合されている(例えば、特許文献1〜3参照)。   Sunscreen cosmetics contain UV absorbers such as benzophenone compounds, paraaminobenzoic acid compounds, and cinnamic acid compounds, and UV scattering agents such as titanium oxide, fine particle titanium oxide, zinc oxide, and fine particle zinc oxide. (For example, refer to Patent Documents 1 to 3).

さらに、UV−A領域の紫外線吸収剤として4−tert−ブチル−4−メトキシジベンゾイルメタンやジエチルアミノヒドロキシベンゾイル安息香酸ヘキシルが知られており、メトキシケイ皮酸2−エチルヘキシルと組み合わせて紫外線吸収効果の持続性を向上させた皮膚外用剤が開発されている。しかしながら、UV−A領域の紫外線吸収剤の多くは常温で固形またはペースト状であり、これらを含んだ日焼け止め化粧料はきしみ感、べたつき感を生じる場合があり、使用感の向上が望まれていた。   Furthermore, 4-tert-butyl-4-methoxydibenzoylmethane and diethylaminohydroxybenzoyl hexyl benzoate are known as UV absorbers in the UV-A region, and have an ultraviolet absorption effect in combination with 2-ethylhexyl methoxycinnamate. A topical skin preparation with improved durability has been developed. However, many UV absorbers in the UV-A region are solid or pasty at room temperature, and sunscreen cosmetics containing these may cause squeaky and sticky feeling, and improvement in the feeling of use is desired. It was.

このような紫外線吸収剤のべたつきを軽減するために様々な試みがなされており、例えば特定のシリコーン誘導体と組み合わせてべたつきを改善することが提案されている(特許文献4参照)。また、一般に日焼け止め化粧料には、汗などにより落ちないよう耐水性が求められている。   Various attempts have been made to reduce such stickiness of the UV absorber, and for example, it has been proposed to improve stickiness in combination with a specific silicone derivative (see Patent Document 4). In general, sunscreen cosmetics are required to have water resistance so that they do not fall off due to sweat or the like.

Yes.

以下、本発明の実施の形態を詳説する。本発明に用いる(A)直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体は、上記一般式(1)で表されるものである。一般式(1)におけるaやb、mやn、x1、x2を変えることにより、本発明の(A)成分は、様々な親水性、親油性のものとなり得るが、本発明では、HLB値が1〜3の直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体が、きしみ感の低減において特に優れるため、好ましく用いられる。尚、本発明における直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体のHLB値は、Soap & Chemical Specialities、No. 6、50〜51(1955)及び化学工業日報、5631号に記載されたポリエーテル変性ポリシロキサンのHLB値測定方法により測定されるものである。 Hereinafter, embodiments of the present invention will be described in detail. The (A) linear copolymer polyether / alkylene / methyl polysiloxane copolymer used in the present invention is represented by the above general formula (1). By changing a, b, m, n, x 1 and x 2 in the general formula (1), the component (A) of the present invention can be various hydrophilic and lipophilic, A linear copolymer polyether / alkylene / methyl polysiloxane copolymer having an HLB value of 1 to 3 is preferably used because it is particularly excellent in reducing squeakiness. In addition, the HLB value of the linear copolymer type polyether-alkylene-methylpolysiloxane copolymer in the present invention is described in Soap & Chemical Specialities, No. 6, 50-51 (1955) and Chemical Industry Daily, 5631. It is measured by the HLB value measuring method of the polyether-modified polysiloxane prepared.

本発明の直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体の性状は、常温で流動性のある液状から軟質ゴム状を示し、25℃において0.0005〜50m/sの動粘度を示すものである。具体的には、ポリオキシエチレン・ブチレン・ジメチルポリシロキサン共重合体、ポリオキシエチレン・ポリオキシプロピレン・ブチレン・ジメチルポリシロキサン共重合体、ポリシリコーン−13などが挙げられ、その市販品の例としては、東レ・ダウコーニング社製のABN SILWETシリーズ(FZ−2203、FZ−2207、FZ−2222、FZ−2231、FZ−2232、FZ−2234、FZ−2233、FZ−2235、FZ−2236、FZ−2237、FZ−2238、FZ−2239、FZ−2250等)が挙げられる。この中でも特に25℃において0.1〜5m/sの動粘度を示す直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体がきしみ感のなさの面で優れており、代表的な市販品の例として東レ・ダウコーニング社製のFZ−2250が挙げられる。 The properties of the linear copolymer polyether-alkylene-methylpolysiloxane copolymer of the present invention are from a fluid liquid to a soft rubber-like shape at room temperature, and have a motion of 0.0005 to 50 m 2 / s at 25 ° C. It indicates the viscosity. Specific examples include polyoxyethylene / butylene / dimethylpolysiloxane copolymer, polyoxyethylene / polyoxypropylene / butylene / dimethylpolysiloxane copolymer, and poly-silicone-13. Is the ABN SILWET series (FZ-2203, FZ-2207, FZ-2222, FZ-2231, FZ-2232, FZ-2234, FZ-2233, FZ-2235, FZ-2236, FZ, manufactured by Toray Dow Corning -2237, FZ-2238, FZ-2239, FZ-2250, and the like. Among them, a linear copolymer polyether / alkylene / methyl polysiloxane copolymer exhibiting a kinematic viscosity of 0.1 to 5 m 2 / s at 25 ° C. is particularly excellent in terms of lack of squeakiness. An example of a commercially available product is FZ-2250 manufactured by Toray Dow Corning.

本発明の日焼け止め化粧料における(A)直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体の配合量は、日焼け止め化粧料の総量を基準として0.01〜5.0質量%(以下、単に%と略す。)が好ましく、特に好ましくは0.1〜2.0%である。直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体の配合量がこれらの範囲内であれば、きしみ感やべたつき感がより効果的に抑制された化粧料が
得られる。
The blending amount of the (A) linear copolymer type polyether / alkylene / methyl polysiloxane copolymer in the sunscreen cosmetic of the present invention is 0.01 to 5.0% by mass based on the total amount of the sunscreen cosmetic. (Hereinafter simply abbreviated as “%”) is preferred, with 0.1 to 2.0% being particularly preferred. When the blending amount of the linear copolymer type polyether / alkylene / methylpolysiloxane copolymer is within these ranges, a cosmetic in which the squeaky feeling and the sticky feeling are more effectively suppressed can be obtained.

本発明において(A)直鎖共重合型ポリエーテル・アルキレン・メチルポリシロキサン共重合体は、シリコーン骨格を有することから肌に滑り性を与えべたつきのなさに影響し、ポリエーテル基に由来する保湿性からきしみ感の軽減に影響すると考えられる。しかしながら同様にシリコーン骨格、ポリエーテル基を有するペンダント型ポリエーテル変性ポリシロキサン共重合体では本発明の効果を発揮できない。   In the present invention, the (A) linear copolymer-type polyether / alkylene / methylpolysiloxane copolymer has a silicone skeleton, so that the skin is slippery and has no stickiness, and is moisturizing derived from a polyether group. It is thought that it influences the reduction of squeakiness from the nature. However, a pendant polyether-modified polysiloxane copolymer having a silicone skeleton and a polyether group cannot exhibit the effects of the present invention.

本発明に用いられる(B)ポリメチルシルセスキオキサンは、メチルトリメトキシシロキサンをアルカリ水溶液中で乳化重合させた球状粉体であり、具体的には、モメンティブ・パフォーマンス・マテリアルズ社製のトスパールシリーズ(トスパール145A等)が挙げられる。   (B) Polymethylsilsesquioxane used in the present invention is a spherical powder obtained by emulsion polymerization of methyltrimethoxysiloxane in an alkaline aqueous solution. Specifically, Toss manufactured by Momentive Performance Materials, Inc. The pearl series (Tospearl 145A etc.) is mentioned.

本発明の日焼け止め化粧料におけるポリメチルシルセスキオキサンの配合量は、日焼け止め化粧料の総量を基準として0.1〜8.0%が好ましく、特に好ましくは0.2〜4.0%である。ポリメチルシルセスキオキサンの配合量がこれらの範囲内であれば、優れた使用感の持続性が向上し、きしみ感の抑制効果に特に優れる。   The blending amount of polymethylsilsesquioxane in the sunscreen cosmetic of the present invention is preferably 0.1 to 8.0%, particularly preferably 0.2 to 4.0%, based on the total amount of the sunscreen cosmetic. It is. When the blending amount of polymethylsilsesquioxane is within these ranges, the durability of the excellent feeling of use is improved and the effect of suppressing the squeaky feeling is particularly excellent.

本発明において(B)ポリメチルシルセスキオキサンは、シリコーン骨格を有する球状粉体であることから肌に滑り性を与え、べたつきのなさに影響されると考えられる。しかしながら、同様にシリコーン骨格を有する球状粉体である(ジメチコン/ビニルメチコン)クロスポリマーでは本発明の効果を発揮できない。   In the present invention, since (B) polymethylsilsesquioxane is a spherical powder having a silicone skeleton, it is considered that it gives slipperiness to the skin and is influenced by non-stickiness. However, the effect of the present invention cannot be exhibited by a (dimethicone / vinyl methicone) crosspolymer which is also a spherical powder having a silicone skeleton.

本発明に用いられる(C)20℃で固形状又はペースト状を呈し、UV−A領域に最大吸収波長を有する紫外線吸収剤としては、具体的には4−tert−ブチル−4−メトキシジベンゾイルメタン、ジエチルアミノヒドロキシベンゾイル安息香酸ヘキシル、ジメトキシベンジリデンジオキソイミダゾリジンプロピオン酸2−エチルヘキシル、メチレンビズベンゾトリアゾリルテトラメチルブチルフェノール、ビスエチルヘキシルオキシフェノールメトキシフェニルトリアジンなどが挙げられ、これらは市販されている。これらの中でもジエチルアミノヒドロキシベンゾイル安息香酸ヘキシルがきしみ感のなさで最も優れる。尚、本発明でいう固体状又はペースト状とは、米国材料試験協会(ASTM)の標準試験法D43590−90による定義に従う。   (C) As an ultraviolet absorber having a solid or paste form at 20 ° C. and having a maximum absorption wavelength in the UV-A region, specifically used is 4-tert-butyl-4-methoxydibenzoyl. Examples include methane, diethylaminohydroxybenzoyl hexyl benzoate, dimethoxybenzylidenedioxoimidazolidine 2-ethylhexyl propionate, methylene benzobenzotriazolyl tetramethylbutylphenol, bisethylhexyloxyphenol methoxyphenyl triazine, and the like, which are commercially available. Among these, diethylaminohydroxybenzoyl hexyl benzoate is most excellent in the absence of squeaking. In the present invention, the solid state or the paste state conforms to the definition by the American Society for Testing and Materials (ASTM) standard test method D43590-90.

本発明の日焼け止め化粧料における20℃で固形状又はペースト状を呈し、UV−A領域に最大吸収波長を有する紫外線吸収剤の配合量は、日焼け止め化粧料の総量を基準として0.1〜5.0%が好ましく、特に好ましくは0.3〜3.0%である。UV−A紫外線吸収剤の配合量がこれらの範囲内であれば、より優れた紫外線防御効果が発揮され、使用感についても特に優れたものとなる。   In the sunscreen cosmetic of the present invention, the blending amount of the ultraviolet absorber that is solid or pasty at 20 ° C. and has the maximum absorption wavelength in the UV-A region is 0.1 to 5 based on the total amount of the sunscreen cosmetic. 5.0% is preferable, and 0.3 to 3.0% is particularly preferable. When the blending amount of the UV-A ultraviolet absorber is within these ranges, a more excellent ultraviolet protection effect is exhibited, and the feeling in use is particularly excellent.

本発明の日焼け止め化粧料には、上記の必須成分に加えて必要に応じて上記以外の紫外線吸収剤、上記以外の油性成分、乳化剤(界面活性剤)、紫外線散乱剤、保湿剤、粉体、香料、防腐剤、植物エキス、フッ素化合物、樹脂、粘剤、塩類、溶媒、酸化防止剤、キレート剤、中和剤、pH調整剤、昆虫忌避剤、生理活性成分等を配合することができる。   The sunscreen cosmetic of the present invention includes, in addition to the above essential components, an ultraviolet absorber other than the above, an oily component other than the above, an emulsifier (surfactant), an ultraviolet scattering agent, a humectant, and a powder. , Perfumes, preservatives, plant extracts, fluorine compounds, resins, stickers, salts, solvents, antioxidants, chelating agents, neutralizing agents, pH adjusters, insect repellents, physiologically active ingredients, etc. .

本発明の日焼け止め化粧料とは、紫外線防御機能を付与した化粧料であり、例えばサンスクリーン剤、ファンデーション、化粧下地等が挙げられる。   The sunscreen cosmetic of the present invention is a cosmetic having an ultraviolet protection function, and examples thereof include sunscreen agents, foundations, and makeup bases.
