Description

本発明は、非水系透明油性組成物に関する。さらに詳しくは、ホホバ油を含むにもかかわらず低温（約０℃）で凍結せず、肌へののびおよび浸透性が良く、使用時にべたつかず、さっぱりしており、塗布後にはしっとり感を与える、安定性と使用性に優れた非水系透明油性組成物に関する。   The present invention relates to a non-aqueous transparent oily composition. More specifically, although it contains jojoba oil, it does not freeze at low temperatures (about 0 ° C), spreads well into the skin, is not sticky when used, is refreshing, and gives a moist feeling after application. The present invention relates to a non-aqueous transparent oily composition excellent in stability and usability.

オイル製剤は塗布時に肌へのなじみがよく、使用後にも保湿剤に起因するべたつきがない点から、近年開発が盛んに行われている皮膚化粧料である。なかでも外観上も美観を損なうことのない透明タイプが人気を博している。   Oil formulations are skin cosmetics that have been actively developed in recent years because they are well-familiar to the skin when applied and are not sticky due to moisturizers after use. Among them, the transparent type that does not impair the aesthetic appearance is gaining popularity.

例えば、特許文献１には、液状動植物油、シリコーン油、算出ＨＬＢ値が５〜８である非イオン性界面活性剤の１種又は２種以上を含有する液状油性ボディオイル組成物が提案されている。この液状油性ボディオイル組成物は、入浴後の濡れた肌に直接塗布し、その後に軽くすすぐ方法で使用される。当該文献によれば、保湿成分として液状動植物油、感触改善剤としてシリコーン油、すすぎ流し成分として非イオン性界面活性剤を組合せて含有させることにより、使用性に優れ、肌をつるつるとした状態にし、しっとりとした感触と高い保湿力を与え、安定性も良好であるとされている。しかしながら、すすぎ流しを必須とするものは、肌表面に残る油分が少ないため、肌の表面を油分で覆うことによって肌からの水分の蒸発を防ぐという観点からの保湿ケアとしては十分とは言えない場合がある。   For example, Patent Document 1 proposes a liquid oily body oil composition containing one or more of a liquid animal and vegetable oil, a silicone oil, and a nonionic surfactant having a calculated HLB value of 5 to 8. Yes. This liquid oily body oil composition is applied directly to wet skin after bathing, and then lightly rinsed. According to the document, liquid animal and vegetable oils are used as moisturizing ingredients, silicone oil is used as a feel-improving agent, and a nonionic surfactant is used as a rinse-off ingredient. It gives a moist feel and high moisturizing power and is said to have good stability. However, those that require rinsing are not sufficient as moisturizing care from the viewpoint of preventing the evaporation of moisture from the skin by covering the skin surface with oil because there is little oil remaining on the skin surface. There is a case.

そこで、このようなすすぎ流しを必要としない非水系の保湿ケア剤として、スクワランや流動パラフィンなどの炭化水素系の油性成分を含むオイル製剤が提案されている（特許文献２〜４）。これらのオイル製剤は、肌表面を油分で覆って皮膚が持つ水分の揮散を適度に制御し、皮膚を柔軟にする効果および保湿効果を発揮するとされている。   Thus, oil formulations containing hydrocarbon oil components such as squalane and liquid paraffin have been proposed as non-aqueous moisturizing care agents that do not require rinsing (Patent Documents 2 to 4). These oil preparations are said to exhibit an effect of softening the skin and a moisturizing effect by covering the skin surface with oil and appropriately controlling the volatilization of moisture of the skin.

ところで、このようなオイル製剤には、感触がよく、植物由来で安全性にも優れていることから、ホホバ油が頻繁に用いられる（特許文献２〜４）。しかしながら、ホホバ油は１０℃程度で凝固してしまうことから、ホホバ油を含有するオイル製剤は、冬場や低温地域においてしばしば凍結を生じてしまう。凍結によりオイル製剤としての品質が著しく損なわれることはないものの、使用の度に、凍結した製剤を常温（２５℃程度）に戻して融解する必要があった。   Incidentally, jojoba oil is frequently used for such an oil formulation because it has a good feel, is derived from a plant and is excellent in safety (Patent Documents 2 to 4). However, since jojoba oil coagulates at about 10 ° C., an oil formulation containing jojoba oil often freezes in winter and low temperature areas. Although the quality as an oil preparation is not significantly impaired by freezing, it is necessary to return the frozen preparation to room temperature (about 25 ° C.) and melt it every time it is used.

本発明は、前記事情に鑑みてなされたものであり、ホホバ油を含有するにもかかわらず、低温下（約０℃）で長時間保管しても凍結せず、透明性の維持効果に優れ、しかも皮膚に塗布する際にべたつかず、のびが良く、浸透性に優れ、さっぱりとした感触を有し、塗布後にしっとり感を与える、非水系透明油性組成物を提供することを目的とする。   The present invention has been made in view of the above circumstances, and although it contains jojoba oil, it does not freeze even when stored at a low temperature (about 0 ° C.) for a long time, and has an excellent transparency maintaining effect. Moreover, it is an object to provide a non-aqueous transparent oily composition that is non-sticky when applied to the skin, has good spread, has good permeability, has a refreshing feel, and gives a moist feeling after application.

本発明者は、鋭意研究を重ねた結果、２５℃における粘度が２０ｍＰａ・ｓ以下のジメチルポリシロキサンと、有機概念図におけるＩＯＢが０．１〜０．６のエステル油と、ホホバ油を除く２５℃で液状〜粘性液状である油脂及び／又は非極性油とを特定の割合にて配合することにより、ホホバ油を含有する非水系透明油性組成物に係る前記課題を解決できることを見出し、本発明を完成するに至った。   As a result of extensive research, the inventor has removed 25 dimethylpolysiloxane having a viscosity at 25 ° C. of 20 mPa · s or less, an ester oil having an IOB of 0.1 to 0.6 in an organic conceptual diagram, and jojoba oil. The present invention finds that the above-mentioned problem relating to a non-aqueous transparent oil-based composition containing jojoba oil can be solved by blending oil and / or non-polar oil that is liquid to viscous liquid at a specific temperature at a specific temperature. It came to complete.

Can be mentioned.

これらのシリコーン油の中でも、とりわけ肌へのなじみの観点から、粘度１０ｍＰａ・ｓ以下のシリコーン油が好ましく、さらに好ましくは粘度６ｍＰａ・ｓ以下のものが好ましく、最も好ましくは粘度２ｍＰａ・ｓ以下のものが好ましい。   Among these silicone oils, a silicone oil having a viscosity of 10 mPa · s or less is preferable from the viewpoint of familiarity with the skin, more preferably a viscosity of 6 mPa · s or less, and most preferably a viscosity of 2 mPa · s or less. Is preferred.

成分（ａ）のシリコーン油の含有量は、組成物全体に対して、１０．０〜３０．０質量％であり、好ましくは、１５．０〜２５．０質量％である。１０．０質量％未満では、低温下（約０℃）での凍結抑制に十分な効果を発揮しにくい。一方、３０．０質量％を超えて配合すると、０℃よりさらに低温でも凍結しにくくなるが、べたつき、さっぱりさ、浸透感が劣り、使用性に物足りなさを感じるようになってしまう。通常、本発明に係る組成物は住居内で使用されるものであり、住居内の室温が０℃より低温になることは考えにくいことから、０℃より低温になることまで想定してシリコーン油の配合量を多くする必要はない。しかし、使用温度が０℃より低くなる地域や環境に合わせて、上記範囲を超えて配合することを妨げるものではなく、本発明の効果を著しく損なわない範囲内であれば当該シリコーン油の配合量を適宜増やしてもよい。   Content of the silicone oil of a component (a) is 10.0-30.0 mass% with respect to the whole composition, Preferably, it is 15.0-25.0 mass%. If it is less than 10.0% by mass, it is difficult to exert an effect sufficient for freezing suppression at a low temperature (about 0 ° C.). On the other hand, when it exceeds 30.0% by mass, it becomes difficult to freeze even at a temperature lower than 0 ° C., but stickiness, refreshment and penetration are inferior, and the usability becomes unsatisfactory. Usually, the composition according to the present invention is used in a house, and since it is unlikely that the room temperature in the house is lower than 0 ° C., it is assumed that the temperature is lower than 0 ° C. It is not necessary to increase the blending amount. However, according to the region and environment where the use temperature is lower than 0 ° C., it does not prevent blending beyond the above range, and the blending amount of the silicone oil is within the range not significantly impairing the effects of the present invention May be increased as appropriate.

＜成分（ｂ）：有機概念図におけるＩＯＢが０．１〜０．６のエステル油＞
有機概念図とは、藤田穆により提案されたものであり、その詳細は“Ｐｈａｒｍａｃｅｕｔｉｃａｌ Ｂｕｌｌｅｔｉｎ”，ｖｏｌ．２，２，ｐｐ．１６３−１７３（１９５４）、「化学の領域」ｖｏｌ．１１，１０，ｐｐ．７１９−７２５（１９５７）、「フレグランスジャーナル」，ｖｏｌ．５０．ｐｐ．７９−８２（１９８１）等に説明されている。すなわち、すべての有機化合物の根源をメタン（ＣＨ４）とし、他の化合物は、すべてメタンの誘導体とみなして、その炭素数、置換基、結合様式（単結合、二重結合、三重結合の違い）、環等にそれぞれ一定の数値を設定し、そのスコアを加算して有機性値、無機性値を求め、有機性値をＸ軸、無機性値をＹ軸にとった図上にプロットしていくものである。有機概念図については、「有機概念図−基礎と応用−」（甲田善生著、三共出版、１９８４）等にも示されている。
有機概念図におけるＩＯＢとは、Ｉｎｏｒｇａｎｉｃ／Ｏｒｇａｎｉｃ Ｂａｌａｎｃｅの略であって、有機概念図における有機性値（ＯＶ）に対する無機性値（ＩＶ）の比、すなわち、「無機性値（ＩＶ）／有機性値（ＯＶ）」を指す。 <Component (b): Ester oil having an IOB of 0.1 to 0.6 in the organic conceptual diagram>
The organic conceptual diagram was proposed by Satoshi Fujita, and details thereof are described in “Pharmaceutical Bulletin”, vol. 2,2, pp. 163-173 (1954), “Area of Chemistry” vol. 11, 10, pp. 719-725 (1957), "Fragrance Journal", vol. 50. pp. 79-82 (1981). In other words, the source of all organic compounds is methane (CH 4 ), all other compounds are all regarded as derivatives of methane, and the number of carbon atoms, substituents, and bonding modes (difference in single bond, double bond, triple bond) ), Set a certain numerical value for each ring, etc., add the scores to find the organic and inorganic values, and plot them on a diagram with the organic value on the X axis and the inorganic value on the Y axis. It will be. The organic conceptual diagram is also shown in “Organic Conceptual Diagram-Basics and Applications” (written by Yoshio Koda, Sankyo Publishing, 1984).
The IOB in the organic conceptual diagram is an abbreviation of Inorganic / Organic Balance, and the ratio of the inorganic value (IV) to the organic value (OV) in the organic conceptual diagram, that is, “inorganic value (IV) / organic property Value (OV) ".

本発明に用いられる成分（ｂ）のエステル油としては、例えば、２−エチルヘキサン酸２−エチルヘキシル（ＩＯＢ＝０．２）、ジネオペンタン酸トリプロピレングリコール（ＩＯＢ＝０．５２）、イソデシルベンゾエート（ＩＯＢ＝０．２３）、ジカプリル酸プロピレングリコール（ＩＯＢ＝０．３２）、イソノナン酸イソノニル（ＩＯＢ＝０．２）、２−エチルヘキサン酸セチル（ＩＯＢ＝０．５２）、トリ２−エチルヘキサン酸グリセリル（ＩＯＢ＝０．３６）、テトラ２−エチルヘキサン酸ペンタエリスリット（ＩＯＢ＝０．３５）、コハク酸ジ２−エチルヘキシル（ＩＯＢ＝０．３２）等が挙げられるが、これらに限定されるものではない。
本発明においては、成分（ｂ）として、ＩＯＢが０．１〜０．６のエステル油の一種又は二種以上を任意に選択して用いることができる。 Examples of the ester oil of component (b) used in the present invention include 2-ethylhexyl 2-ethylhexanoate (IOB = 0.2), tripropylene glycol dineopentanoate (IOB = 0.52), isodecylbenzoate ( IOB = 0.23), propylene glycol dicaprylate (IOB = 0.32), isononyl isononanoate (IOB = 0.2), cetyl 2-ethylhexanoate (IOB = 0.52), tri-2-ethylhexanoic acid Examples include, but are not limited to, glyceryl (IOB = 0.36), tetra-2-ethylhexanoic acid pentaerythritol (IOB = 0.35), di-2-ethylhexyl succinate (IOB = 0.32), and the like. It is not a thing.
In the present invention, as the component (b), one or more ester oils having an IOB of 0.1 to 0.6 can be arbitrarily selected and used.

ＩＯＢが０．１未満のエステル油を用いると、敏感な肌に対して刺激を生じる場合があり、また使用感の面でもさっぱりせず、べたつく感触を生じる場合がある。一方、ＩＯＢが０．６を超えるエステル油は、水に溶解する性質が高まり、油分としての機能を発揮しなくなる。   When an ester oil having an IOB of less than 0.1 is used, it may cause irritation to sensitive skin, and may cause a feeling of stickiness without being refreshed. On the other hand, an ester oil having an IOB exceeding 0.6 has an increased property of dissolving in water and does not exhibit the function as an oil component.

成分（ｂ）のエステル油の含有量は、組成物全体に対して、１０．０〜３０．０質量％であり、好ましくは、２０．０〜３０．０質量％である。１０．０質量％未満では、本発明の効果であるさっぱりとして、べたつきのない感触を与えることができない。一方、当該エステル油を３０．０質量％を超えて配合しても効果の増強は得られず、却って皮膚への安全性を損なう場合があるため好ましくない。   Content of the ester oil of a component (b) is 10.0-30.0 mass% with respect to the whole composition, Preferably, it is 20.0-30.0 mass%. If it is less than 10.0% by mass, it is impossible to give a non-sticky feeling as a refreshing effect of the present invention.
