Abstract
Description
本発明は、製剤中に含まれる水が塗布時に放出され、水滴となって現れる油中水型乳化組成物に関する。 The present invention relates to a water-in-oil emulsified composition in which water contained in a preparation is released at the time of application and appears as water droplets.
化粧料は、外観を美しく、肌を健やかにすることを主な機能とするが、近年、使用時において、実感できる付加的な機能を備えたものも提案されている。付加的な機能を備えたものとして、例えば、使用の際に温感や冷感を生じさせる化粧料や、肌に塗布することによってエマルジョンが崩壊して水が放出される、いわゆるウォーター−ドロップクイックブレイク型の化粧料(特許文献1〜3)等が提案されている。 The main function of cosmetics is to make the appearance beautiful and to make the skin healthy, but in recent years, those having additional functions that can be felt when used have been proposed. As a product with additional functions, for example, cosmetics that give a feeling of warmth or coldness when used, or so-called water-drop quick, in which an emulsion disintegrates and water is released when applied to the skin. Break-type cosmetics (Patent Documents 1 to 3) and the like have been proposed.
特許文献1〜3に記載の乳化製剤はいずれも、製剤中に水分を保持するため、ネットワーク構造を形成するシリコーンポリマーを用いている。しかし、シリコーンポリマーのようなシリコーン成分は、使用者の肌質によっては、吹き出物やニキビなどのトラブルの原因となることがある。そこで、近年、シリコーンを配合しない、いわゆる「ノンシリコーン」タイプの化粧料が提案され、その認知度および需要が高まっている。このため、ノンシリコーンタイプとして処方を設計することは、化粧料の付加価値の向上につながるといえる。この点、ウォーター−ドロップクイックブレイク型の乳化組成物も同様である。
そこで、本発明は、シリコーンポリマーを用いることなく、製剤中に水分を保持することができ、組成物に含まれる水が塗布時に水滴となって現れる新たな油中水型乳化組成物を提供することを目的としている。

(1) Liquid oil, (B) solid oil, (D) surfactant and BG shown in Tables 1 to 6 are heated to 80 ° C. with stirring, and (C) water-repellent oil-repellent powder (FONCOAT). , Example) or talc, mica, a mixed powder of titanium oxide and iron oxide, cericite, HC PEPE: polyperfluoromethylisopropyl ether (comparative example) was added and uniformly dispersed.
(2) Water (E) heated to 80 ° C. was gradually added while stirring (1) with a propeller at 100 rpm.
(3) While maintaining (2) at 80 ° C., the propeller was stirred at 100 rpm for 30 minutes.
(4) Phenoxyethanol was added to (3), and the mixture was gently stirred and cooled until it reached room temperature to prepare a water-in-oil emulsified composition.
<評価方法>
水の放出度合い、使用感および安定性を、以下の方法に基づいて評価した。評価結果を表1〜表6に示す。
<Evaluation method>
The degree of water release, usability and stability were evaluated based on the following methods. The evaluation results are shown in Tables 1 to 6.
<水の放出度合い(水放出性)>
製剤約1gを手の甲に塗り広げたときに製剤中から水が放出されるか否かを目視で評価した。
○:製剤から水が放出される。
×:製剤から水が放出されない。
<Degree of water release (water release property)>
It was visually evaluated whether or not water was released from the preparation when about 1 g of the preparation was spread on the back of the hand.
◯: Water is released from the preparation.
X: No water is released from the preparation.
<使用感(滑らかさ)>
製剤約1gを手の甲に塗り広げたときの製剤の滑らかさを官能評価により三段階で評価した。
○:滑らかである
△:やや滑らかである
×:滑らかではない
<Usage (smoothness)>
The smoothness of the preparation when about 1 g of the preparation was spread on the back of the hand was evaluated on a three-point scale by sensory evaluation.
○: Smooth △: Slightly smooth ×: Not smooth
<安定性>
50mL容量のポリエチレン(PE)製容器に実施例および比較例の組成物約40gを投入して密封後、1ヶ月間室温(25℃)で静置した後の製剤外観を目視評価した。
○:分離および沈殿のいずれも生じなかった
×:分離または沈殿が生じた
<Stability>
Approximately 40 g of the compositions of Examples and Comparative Examples were placed in a polyethylene (PE) container having a capacity of 50 mL, sealed, and then allowed to stand at room temperature (25 ° C.) for 1 month, and then the appearance of the preparation was visually evaluated.
◯: Neither separation nor precipitation occurred ×: Separation or precipitation occurred
表1、表2に示すように、(C)撥水撥油性紛体の含有量を大きくすることで、組成物の水放出性(内包性)が向上した。ただし、(C)撥水撥油性紛体の含有量が過剰になると、組成物の安定性が低下する傾向が認められた。
表面が撥水撥油処理された粉体を用いることで、無機紛体の種類に関わらず、同様の結果が得られた。
As shown in Tables 1 and 2, the water release property (encapsulation property) of the composition was improved by increasing the content of the (C) water-repellent oil-repellent powder. However, when the content of (C) water- and oil-repellent powder was excessive, the stability of the composition tended to decrease.
By using the powder whose surface was treated with water and oil repellency, the same result was obtained regardless of the type of inorganic powder.
(B)固体油の含有量により、製剤からの水放出性を調整することができた。また、(B)固体油の含有量が大きくなりすぎると、組成物の安定性が低下する傾向が認められた。
(B)固体油は、室温での固体の油であれば、高級アルコール、脂肪酸、植物油、鉱物油など種類を問わず、水放出性および安定性の良好な組成物が得られた。
(B) The water release property from the preparation could be adjusted by the content of the solid oil. Further, when the content of (B) solid oil becomes too large, the stability of the composition tends to decrease.
As long as the solid oil is a solid oil at room temperature, a composition having good water release property and stability was obtained regardless of the type such as higher alcohol, fatty acid, vegetable oil and mineral oil.
表4に示すように、種々の界面活性剤を用いて水の放出性を備えた製剤を調製することができた。安定性の観点から、HLBが12よりも小さい界面活性剤を用いることが好ましいといえる。
As shown in Table 4, various surfactants could be used to prepare water-releasing formulations. From the viewpoint of stability, it can be said that it is preferable to use a surfactant having an HLB of less than 12.
表5の比較例1〜比較例6に示すように、(A)液体油と(B)固体油とを併用することなく、一方のみを用いた場合、水放出性を備えた組成物を得ることができなかった。また、(A)液体油と(B)固体油とを併用したとしても、(C)撥水撥油性紛体を用いなければ、水を放出する油中水型乳化組成物を得ることができなかった。
As shown in Comparative Examples 1 to 6 in Table 5, when only one of (A) liquid oil and (B) solid oil is used without being used in combination, a composition having water release property is obtained. I couldn't. Further, even if (A) liquid oil and (B) solid oil are used in combination, a water-in-oil emulsified composition that releases water cannot be obtained unless (C) a water-repellent oil-repellent powder is used. It was.
表6に示すように、(C)撥水撥油性紛体の代わりに、表面が撥水撥油処理されていない無機紛体を用いた場合、水放出性の良好な組成物を得ることができなかった。この結果から、水放出性を示す組成物を得るためには、紛体表面がPFPOP処理された撥水撥油性紛体を用いる必要があるといえる。 As shown in Table 6, when an inorganic powder whose surface is not treated with water-repellent oil-repellent treatment is used instead of the water-repellent oil-repellent powder (C), a composition having good water-releasing property cannot be obtained. It was. From this result, it can be said that it is necessary to use a water-repellent oil-repellent powder whose surface is treated with PFPOP in order to obtain a composition exhibiting water-releasing property.
図1および図2は、実施例2および比較例8の組成物の図面代用顕微鏡写真である。同図に示すように、実施例2の組成物は、粒子径が10〜30μm程度のマクロエマルジョンであったのに対し、比較例8の組成物は、粒子径が1μm以下のエマルジョンであった。本発明の組成物は、油相中に大きな粒径の水相が分散していることで、良好な水放出性を実現したと考えられる。 1 and 2 are drawing-substituting micrographs of the compositions of Example 2 and Comparative Example 8. As shown in the figure, the composition of Example 2 was a macroemulsion having a particle size of about 10 to 30 μm, whereas the composition of Comparative Example 8 was an emulsion having a particle size of 1 μm or less. .. It is considered that the composition of the present invention has achieved good water release property because the aqueous phase having a large particle size is dispersed in the oil phase.
本発明の油中水型乳化組成物は、ウォーター−ドロップクイックブレイク型の化粧料として有用である。 The water-in-oil emulsified composition of the present invention is useful as a water-drop quick break type cosmetic.
