【発明の属する技術分野】
本発明は保存安定性、使用感触に優れ、塗布により肌上で撥水性を発現することのできる水中油型乳化組成物に関する。
【0002】
【従来の技術】
従来より産業界において乳化組成物は広く使用されている。なかでも乳化組成物、すなわち油中水型あるいは水中油型の選定にあたっては、それぞれの特徴を加味した上で目的や用途に応じて行われている。例えば化粧料用途、とりわけメーキャップ製品や紫外線防御製品については、それぞれ美しさや紫外線防止効果の持続性の観点から、油中水型の乳化組成物が多用されているのが現状である。この主な理由としては、油分が連続層を形成する油中水型組成物の方が、水中油型組成物に比べて適用する肌に対する密着性に優れる点が挙げられる。
【0003】
しかしながら、化粧料として重要な要素である使用感触で見てみると、当然のことながら油中水型乳化組成物の方は油っぽさが強く、特に夏期での使用にあたってはあまり好まれるものではなかった。一方、水中油型乳化組成物の方は、水が連続層を形成するため、感触的にもみずみずしく、さっぱりとしていて年間を通して好まれるものである。
【0004】
ところが、水中油型組成物は水が連続層を形成することに加え、処方構成上必須の親水性界面活性剤を多量に配合せざるを得ないため、汗や水になじみやすく塗布膜の持続性に優れていないという欠点を有していた。このため、水中油型組成物であって、その好ましい使用感触を有しながらも、肌に対する密着性が向上し塗布膜の持続性に優れる構成を提供することが課題であった。この解決のために、従来より、皮膜形成剤を配合したり、肌に対する密着性の高い高粘度油分を配合したり、固形油分を配合したり(下記特許文献1を参照)と、種々の工夫はなされているものの、使用感触面と塗布膜の持続性面の両方を満足する組成物は存在しなかった。
【0005】
【特許文献1】
特許第297345号公報
【0006】
【発明が解決しようとする課題】
本発明は上記問題点に鑑みなされたもので、その目的は、優れた感触、保存安定性を有しながら、塗布により肌上で撥水性を発現し、その結果、塗布膜の持続性に優れる水中油型組成物を提供することにある。
【0007】
【課題を解決するための手段】
本発明は、次の成分(A)〜(D)
(A)両性界面活性剤及び/又は半極性界面活性剤と、高級脂肪酸とを混合して得られる複合体の一種または二種以上0.15〜4.5質量%、
(B)粉末5〜50質量%、
(C)水20〜60質量%、
(D)20℃にて液状である不揮発性油分5〜25質量%
を含有することを特徴とする皮膚用の水中油型乳化組成物である。
【0008】
【発明の実施の形態】
以下、本発明の構成について詳述する。
本発明で水中油型乳化組成物に配合される両性界面活性剤及び/又は半極性界面活性剤は、通常の化粧品基剤等に用いられる両性界面活性剤及び/又は半極性界面活性剤の全てを適用することができる。
【0009】
これらの具体例を挙げると、以下のとおりである。

【0015】
また、半極性界面活性剤としては、下記一般式(6)で表される第三級アミンオキサイド型半極性界面活性剤〔市販品としてユニセーフA−LM(日本油脂製)、ワンダミンOX−100(新日本理化製)等が該当する〕などが例示される。
【0016】
【化12】
Figure 0003889711
【0017】
ただし、上記一般式(1)〜(6)中、R1 は平均炭素原子数9〜21のアルキル基またはアルケニル基、R2 は平均炭素原子数10〜18のアルキル基またはアルケニル基を表す。pは2〜4の整数であり、qは0〜3の整数であり、zは1または2の整数である。また、R1は、平均炭素原子数11~17のアルキル基またはアルケニル基がより好ましく、平均炭素原子数11~13のアルキル基またはアルケニル基が最も好ましい。平均炭素原子数が9未満では、親水性が強すぎ複合体を形成しにくくなる。一方、21を超えると、水への溶解性が悪くなり複合体を形成しにくくなる。
【0018】
本発明においては、界面活性剤成分として、上記した両性界面活性剤および半極性界面活性剤から任意に一種または二種以上を選んで用いることができる。また上記界面活性剤類の配合量は、全成分中の0.1〜4質量%とする。この配合量が不足すると乳化性が悪くなり、多量過ぎるとべたつきが生じるなど、使用感触面での悪化や肌上での撥水性発現にも悪影響を及ぼす。本発明の効果を充分に発揮させるには、0.5〜3質量%が好適である。
【0019】
本発明で配合される脂肪酸としては、例えば、一般式がR3 COOHで表される高級脂肪酸であって、通常の化粧品基剤等に用いられる高級脂肪酸の全てを適応することができる。
【0020】
ここでR3 は、平均炭素原子数が7〜25の直鎖または分岐鎖の飽和もしくは不飽和炭化水素基、または水酸基を有する飽和もしくは不飽和の炭化水素基であることが好ましい。また、上記平均炭素原子数が9〜23であるものがより好ましく、上記平均炭素原子数が11〜21であるものが最も好ましい。平均炭素原子数が7未満では、親水性が強すぎるため複合体が形成されにくくなる。一方、平均炭素原子数が25を超えると融点が高くなるため、同じく複合体が形成されにくくなる。
【0021】
上記高級脂肪酸の具体例としては、ラウリン酸、ミリスチン酸、パルミチン酸、ステアリン酸、アラキン酸、ベヘン酸等の飽和脂肪酸;2−パルミトレイン酸、ペトロセリン酸、オレイン酸、エライジン酸、リシノール酸、リノール酸、リノエライジン酸、リノレン酸、アラキドン酸等の不飽和脂肪酸;イソステアリン酸等の分枝脂肪酸;1,2−ヒドロキシステアリン酸等のヒドロキシカルボン酸等が挙げられる。
【0022】
このうち特に、2−パルミトレイン酸、ペトロセリン酸、オレイン酸、エライジン酸、リシノール酸、リノール酸、リノエライジン酸、リノレン酸、アラキドン酸、イソステアリン酸、1,2−ヒドロキシステアリン酸が好ましい。
【0023】
また、安定性および皮膚刺激性の観点から、炭素原子数18の飽和脂肪酸が好ましく、中でも分岐を有するものが好ましく、メチル分岐を有する炭素原子数18の飽和脂肪酸がさらに好ましい。市販品としては例えば、イソステアリン酸(エメリ−#871、#875(エメリ−社製))などが挙げられる。
【0024】
本発明においては、以上の高級脂肪酸のうちの任意の一種または二種以上が選ばれて用いられる。本発明に用いられる脂肪酸の配合量は、0.05〜4質量%であり、配合量が不足しても、多量過ぎても安定性面での悪化をもたらす。本発明の効果を充分に発揮させるには、0.1〜3質量%が好適である。
【0025】
本発明で用いられる成分(A)の両性界面活性剤及び/又は半極性界面活性剤と高級脂肪酸とを混合して得られる複合体は、高級脂肪酸のカルボキシル基部分で両性界面活性剤及び/又は半極性界面活性剤と結合したもので、優れた乳化剤であり、その詳細は、特開平6−65596号公報に記載されている。
【0026】
本発明において、高級脂肪酸と界面活性剤との配合比は、高級脂肪酸:両性界面活性剤及び/又は半極性界面活性剤の質量比が、0.5:9.5〜9.5:0.5、より好ましくは、1:9〜9:1となるようにするのが安定性の点でよい。
【0027】
上記界面活性剤成分と高級脂肪酸からなる複合体(A)の合計量は、0.15〜4.5質量%とすることが好ましく、0.5〜3.5質量%とすることがより好ましい。0.15質量%未満であると乳化物の安定性が悪化する。一方、4.5質量%を超えて配合すると使用感触だけでなく、保存安定性、撥水性にも悪影響をもたらすため、その上限は4.5質量%とすることが好ましい。
【0028】
本発明で配合される粉末(B)は特に限定されるものではないが、無機顔料および有機顔料が挙げられる。無機顔料の例としては、タルク、カオリン、炭酸カルシウム、亜鉛華、二酸化チタン、赤酸化鉄、黄酸化鉄、黒酸化鉄、群青、チタンコーティッドマイカ、オキシ塩化ビスマス、ベンガラ、粘結顔料、グンジョウピンク、水酸化クロム、雲母チタン、酸化クロム、酸化アルミニウムコバルト、紺青、カーボンブラック、無水ケイ酸、ケイ酸マグネシウム、ベントナイト、マイカ、酸化ジルコニウム、酸化マグネシウム等が例示される。
【0029】
有機顔料としては、オルガノポリシロキサンエラストマー、ポリメチルシルセスキオキサン、ポリエチレン、ポリプロピレン、ウレタン、ナイロン、メタクリル酸メチルポリマー、ポリスチレン、ポリスチレン−ポリアクリル酸共重合体、塩化ビニルポリマー、テトラフルオロエチレンポリマー等の粉末や、セルロースパウダー、キチンパウダー、キトサンパウダー、魚鱗箔、レーキ化タール色素等が例示される。
【0030】
またこれらの顔料は、疎水化処理などの表面処理を施したもの、あるいは製造工程上で疎水性を付与したものも応用できる。例えば、高粘度シリコーン油処理、アルキルハイドロジェンポリシロキサンを反応させたシリコーン樹脂処理、あるいはそれらをアルケン処理したもの、カチオン活性剤処理、アニオン活性剤処理、ノニオン活性剤処理、ワックス処理、デキストリン脂肪酸処理、フッ素処理等が例示される。
【0031】
本発明に用いられる粉末(B)の配合量は5〜50質量%であり、5質量%未満では、さっぱりとした好ましい感触が充分に発揮されず、50質量%を超えて配合すると使用感触面でのびが重く肌上での広がりに難が生じたり、粉っぽさが生じるなどの不都合をもたらす。本発明の効果を充分に発揮させるには、15〜35質量%が好適である。
【0032】
本発明に用いられる水(C)の配合量は1〜90質量%であり、水中油型組成物を構成できる量であれば本発明の効果を損なわない。みずみずしい使用感触やさっぱりさを充分に付与させるためには、20〜60質量%が好適である。
【0033】
本発明に用いられる20℃にて液状である不揮発性油分(D)としては、極性油から非極性油まで幅広く、例えば、
流動パラフィン、分岐鎖状軽パラフィン、パラフィンワックス、セレシン、スクワラン等の炭化水素;
蜜ロウ、鯨コウ、カルナバロウ等のワックス類;
オリーブ油、椿油、ホホバ油、ラノリン等の天然動植物油脂;
イソプロピルミリステート、セチルイソオクタノエート、グリセリルトリオクタノエート等のエステル油;
ジメチルポリシロキサン、メチルフェニルポリシロキサン等のシリコーン油;
セチルアルコール、ステアリルアルコール、オレイルアルコール等の高級アルコール等
が挙げられ、これらのものを単独で、または二種以上の混合物として含有しているものでもよい。
【0034】
不揮発性油分(D)の配合量は、2〜40質量%であり、水中油型組成物を構成できる量であれば本発明の効果を損なわない。油っぽさなどの使用感触面での悪化をもたらさない配合量としては5〜25質量%が好適である。不揮発性油分(D)の配合量が少なすぎると塗布膜が充分な撥水性を発揮しない。
【0035】
本発明においては、油分として上記(D)成分以外の油分を用いることが可能である。かかる油分としては例えばデカメチルペンタシロキサンなどの揮発性油分が挙げられる。
【0036】
本発明においては、増粘剤を配合することにより、さらに安定な組成物を得ることができる。増粘剤としては、通常化粧料に用いられるものを使用することができ、例えばサクシノグリカン、キサンタンガム等を使用することができる。
【0037】
本発明においては上記成分のほかに、水中油型組成物を構成する成分として配合される、界面活性剤、保湿剤、低級アルコールや、水中油型組成物を修飾する成分として防腐剤、香料、キレート剤、酸化防止剤、紫外線吸収剤、ゲル化剤等が配合できることは言うまでもない。
【0038】

実施例1と処方例a〜eの撥水性評価
下記[表2]に記載された通常のノニオン乳化系の水中油型ファンデーションに係る処方例a〜cおよび、下記[表3]に記載されたノニオン乳化系の油中水型ファンデーションに係る処方例d,eおよび上記実施例1で得た試料を試験品として用意し、以下の試験を行った。
【0048】
すなわち、下記[表2]、[表3]に記載の試験品を人工皮革表面に、塗布量が1mg/cm2 となるように塗布し、3μl(マイクロリットル)のイオン交換水に対する接触角を求めた。なお、接触角は、これが大きいほど撥水性が高いことを示す。
また、前記した方法で化粧持続性を評価した。これらの結果を下記[表4]に示す。
【0049】

【0052】
上記[表4]の結果から、上記[表2]に記載された通常のノニオン乳化系の水中油型ファンデーション処方例a〜cでは、不揮発性油分が配合されていても良好な撥水性は得られないが、本発明の水中油型乳化ファンデーション(実施例1)では、水中油型乳化ファンデーションでありながら、処方例d,eのような油中水型ファンデーションに匹敵する撥水性が得られることがわかる。また、撥水性に優れるものは化粧持続性にも優れ、これらには相関関係があることがわかる。
【0053】
また、上記[表1]から分かるように、実施例1の試料を塗布した群では、いずれの項目についても好評価であり、比較例1〜5の試料を塗布した群では、すべての項目を満足させることはなかった。このことは、本発明の化粧料が従来のものに比べて保存安定性、使用感触、撥水性に優れていることを示している。

BACKGROUND OF THE INVENTION
The present invention relates to an oil-in-water emulsion composition which is excellent in storage stability and use feeling and can exhibit water repellency on the skin by application.
[0002]
[Prior art]
Conventionally, emulsified compositions have been widely used in industry. In particular, the emulsified composition, that is, the water-in-oil type or the oil-in-water type is selected according to the purpose and application in consideration of the respective characteristics. For example, for cosmetics, especially makeup products and UV protection products, water-in-oil emulsion compositions are frequently used from the viewpoint of beauty and durability of UV protection effects. The main reason for this is that the water-in-oil composition in which the oil component forms a continuous layer is superior in adhesion to the applied skin compared to the oil-in-water composition.
[0003]
However, when looking at the feel of use, which is an important factor for cosmetics, it is natural that the water-in-oil emulsion composition is more oily and is particularly preferred for use in summer. It wasn't. On the other hand, the oil-in-water emulsion composition is preferred throughout the year because water forms a continuous layer, so that it is fresh and refreshing to the touch.
[0004]
However, in the oil-in-water composition, in addition to forming a continuous layer of water, it is necessary to blend a large amount of the hydrophilic surfactant that is essential for the composition of the composition. It had the defect that it was not excellent in property. For this reason, it was a subject to provide the structure which is an oil-in-water type composition, and has the favorable feeling of use, but the adhesiveness with respect to skin improves and it is excellent in the sustainability of a coating film. In order to solve this problem, various devices such as a film forming agent, a high-viscosity oil component having high adhesion to the skin, and a solid oil component (see Patent Document 1 below) have been conventionally used. However, there has been no composition that satisfies both the feel of use and the durability of the coated film.
[0005]

[0017]
However, in the general formula (1) ~ (6), R 1 is an average alkyl or alkenyl group having a carbon number of 9 to 21, R 2 represents an alkyl group or alkenyl group having an average carbon number from 10 to 18. p is an integer of 2 to 4, q is an integer of 0 to 3, and z is an integer of 1 or 2. R 1 is more preferably an alkyl group or alkenyl group having an average carbon number of 11 to 17, and most preferably an alkyl group or alkenyl group having an average carbon number of 11 to 13. If the average number of carbon atoms is less than 9, the hydrophilicity is too strong to form a complex. On the other hand, when it exceeds 21, the solubility in water becomes poor and it is difficult to form a complex.
[0018]
In the present invention, as the surfactant component, one or two or more kinds can be arbitrarily selected from the amphoteric surfactant and the semipolar surfactant described above. Moreover, the compounding quantity of the said surfactant shall be 0.1-4 mass% in all the components. If the blending amount is insufficient, the emulsifiability is deteriorated, and if the amount is too large, stickiness is caused, and the use feeling is adversely affected and the water repellency expression on the skin is also adversely affected. In order to exhibit the effect of this invention fully, 0.5-3 mass% is suitable.
[0019]
As the fatty acid blended in the present invention, for example, higher fatty acids represented by the general formula R 3 COOH, and all higher fatty acids used in ordinary cosmetic bases can be applied.
[0020]
Here, R 3 is preferably a linear or branched saturated or unsaturated hydrocarbon group having an average carbon number of 7 to 25, or a saturated or unsaturated hydrocarbon group having a hydroxyl group. Further, those having 9 to 23 average carbon atoms are more preferable, and those having 11 to 21 average carbon atoms are most preferable. When the average number of carbon atoms is less than 7, since the hydrophilicity is too strong, it is difficult to form a complex. On the other hand, when the average number of carbon atoms exceeds 25, the melting point becomes high, so that it is also difficult to form a composite.
[0021]
Specific examples of the higher fatty acids include saturated fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, and behenic acid; 2-palmitoleic acid, petrothelic acid, oleic acid, elaidic acid, ricinoleic acid, linoleic acid And unsaturated fatty acids such as linoelaidic acid, linolenic acid and arachidonic acid; branched fatty acids such as isostearic acid; and hydroxycarboxylic acids such as 1,2-hydroxystearic acid.
[0022]
Of these, 2-palmitoleic acid, petrothelic acid, oleic acid, elaidic acid, ricinoleic acid, linoleic acid, linoelaidic acid, linolenic acid, arachidonic acid, isostearic acid, and 1,2-hydroxystearic acid are particularly preferable.
[0023]
Further, from the viewpoint of stability and skin irritation, a saturated fatty acid having 18 carbon atoms is preferable, among which a branched fatty acid is preferable, and a saturated fatty acid having 18 carbon atoms having a methyl branch is more preferable. Examples of commercially available products include isostearic acid (Emery- # 871, # 875 (manufactured by Emery)).
[0024]
In the present invention, any one or two or more of the above higher fatty acids are selected and used. The blending amount of the fatty acid used in the present invention is 0.05 to 4% by mass, and even if the blending amount is insufficient or too large, deterioration in stability is brought about. In order to exhibit the effect of this invention fully, 0.1-3 mass% is suitable.
[0025]
The composite obtained by mixing the amphoteric surfactant and / or semipolar surfactant of the component (A) used in the present invention with a higher fatty acid is an amphoteric surfactant at the carboxyl group portion of the higher fatty acid and / or It is combined with a semipolar surfactant and is an excellent emulsifier, and details thereof are described in JP-A-6-65596.
[0026]
In the present invention, the mixing ratio of the higher fatty acid and the surfactant is such that the mass ratio of higher fatty acid: amphoteric surfactant and / or semipolar surfactant is 0.5: 9.5 to 9.5: 0. 5, More preferably, the ratio may be 1: 9 to 9: 1 in terms of stability.
[0027]
The total amount of the complex (A) composed of the surfactant component and the higher fatty acid is preferably 0.15 to 4.5% by mass, and more preferably 0.5 to 3.5% by mass. . If it is less than 0.15% by mass, the stability of the emulsion deteriorates. On the other hand, if it exceeds 4.5% by mass, not only the feel of use but also storage stability and water repellency are adversely affected, so the upper limit is preferably 4.5% by mass.
[0028]
Although the powder (B) mix | blended by this invention is not specifically limited, An inorganic pigment and an organic pigment are mentioned. Examples of inorganic pigments include talc, kaolin, calcium carbonate, zinc white, titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide, ultramarine, titanium coated mica, bismuth oxychloride, bengara, caking pigment, gun Examples include Zaw Pink, chromium hydroxide, mica titanium, chromium oxide, aluminum cobalt oxide, bitumen, carbon black, anhydrous silicic acid, magnesium silicate, bentonite, mica, zirconium oxide, magnesium oxide and the like.

These pigments can also be applied to those having been subjected to a surface treatment such as a hydrophobization treatment, or to those having been made hydrophobic in the production process. For example, high-viscosity silicone oil treatment, silicone resin treatment with alkyl hydrogen polysiloxane, or those treated with alkene, cation activator treatment, anion activator treatment, nonionic activator treatment, wax treatment, dextrin fatty acid treatment And fluorine treatment.
[0031]
The blending amount of the powder (B) used in the present invention is 5 to 50% by mass, and if it is less than 5% by mass, a refreshing and preferable feel is not sufficiently exhibited. The spread is heavy and causes problems such as difficulty in spreading on the skin and powderiness. In order to fully exhibit the effects of the present invention, 15 to 35% by mass is preferable.
[0032]
The compounding quantity of water (C) used for this invention is 1-90 mass%, and if the quantity which can comprise an oil-in-water type composition, the effect of this invention is not impaired. 20-60 mass% is suitable in order to give a fresh use feeling and refreshing enough.
[0033]

The blending amount that does not cause deterioration in use feeling such as oiliness is preferably 5 to 25% by mass. When there is too little compounding quantity of a non-volatile oil component (D), a coating film will not exhibit sufficient water repellency.
[0035]
In the present invention, oil other than the component (D) can be used as the oil. Examples of such oil include volatile oil such as decamethylpentasiloxane.
[0036]
In the present invention, a more stable composition can be obtained by blending a thickener. As a thickener, what is normally used for cosmetics can be used, for example, succinoglycan, xanthan gum, etc. can be used.
