Description
本発明は、油中水型乳化化粧料に関する。 The present invention relates to a water-in-oil emulsion cosmetic.
従来から、皮脂等の汚れやメイクアップ化粧料の除去のために、水性化粧料(化粧水等)や、水性化粧料のようなさっぱりとした使用感を目的とした水中油型乳化化粧料が使用されている。しかし、これらのような水を外相とする水性化粧料や水中油型乳化化粧料では、油性マスカラ等の油性メイクアップ化粧料に対して除去力が不十分であった。 Conventionally, aqueous cosmetics (lotions, etc.) and oil-in-water emulsion cosmetics that aim to provide a refreshing feel when used like aqueous cosmetics have been used to remove dirt such as sebum and makeup cosmetics. However, these aqueous cosmetics and oil-in-water emulsion cosmetics that have water as the external phase have insufficient removing power for oil-based makeup cosmetics such as oil-based mascara.
一方、油性化粧料は、皮脂等の汚れや油性メイクアップ化粧料に対する高い除去力を有するが、除去後のべたつきについて更に洗浄を必要とすることがあった。そのため、べたつきを低減し洗浄を不要とすることを目的として、内相として水性成分を有する油中水型乳化化粧料を用いることが提案されている(特許文献1~4)。 On the other hand, oil-based cosmetics have a high ability to remove dirt such as sebum and oil-based makeup cosmetics, but they can be sticky after removal and require further washing. Therefore, it has been proposed to use water-in-oil emulsion cosmetics that have an aqueous component as the internal phase in order to reduce stickiness and eliminate the need for washing (Patent Documents 1 to 4).
しかしながら、特許文献1~4の油中水型乳化化粧料には、高い除去力を有するものの、高粘度であるため、使用後の拭取りの際や、シート化粧料として使用する際に、シート基材への含浸が容易ではないという問題があった。 However, although the water-in-oil emulsified cosmetics of Patent Documents 1 to 4 have high removal power, they have high viscosity, so when wiping them off after use or when using them as sheet cosmetics, they cannot be used as sheet cosmetics. There was a problem in that it was not easy to impregnate the base material.
従って、本発明の目的は、メイクアップ化粧料の除去力に優れ、かつ低粘度である、油中水型乳化化粧料を提供することにある。本発明の目的は、また、上記油中水型乳化化粧料をシート基材に含浸させたシート化粧料を提供することにある。 Therefore, an object of the present invention is to provide a water-in-oil emulsion cosmetic that has excellent makeup removal power and low viscosity. Another object of the present invention is to provide a sheet cosmetic in which the above water-in-oil emulsion cosmetic is impregnated into a sheet substrate.

本発明の油中水型乳化化粧料では、界面活性剤として、特定のポリグリセリンジ脂肪酸エステルと特定のポリグリセリンモノ脂肪酸エステルとを、特定の質量割合で併用することを特徴としている。これにより、極めて安定な油中水型の乳化状態を形成しうる。一般的には、界面活性剤のみで安定した油中水型の乳化状態を形成することは困難なため、油相の粘度を高めることによって乳化状態を安定化するところ、本発明においては、低粘度であっても安定した油中水型乳化化粧料を形成できる。これにより、クレンジング特性(メイクアップの除去性)に優れる油中水型乳化化粧料の、拭き取り時のコットン等への含浸性が良好であり、使用性に優れる。また、シート化粧料とする場合には生産性が向上する。 The water-in-oil emulsified cosmetic composition of the present invention is characterized in that a specific polyglycerin difatty acid ester and a specific polyglycerin monofatty acid ester are used together in a specific mass ratio as surfactants. This makes it possible to form an extremely stable water-in-oil emulsion. Generally, it is difficult to form a stable water-in-oil emulsion using surfactants alone, so the emulsion is stabilized by increasing the viscosity of the oil phase. A stable water-in-oil emulsion cosmetic can be formed even at low viscosity. As a result, the water-in-oil emulsion cosmetic, which has excellent cleansing properties (removability of makeup), has good impregnation properties into cotton etc. during wiping, and is excellent in usability. Moreover, when it is used as a sheet cosmetic, productivity is improved.

表に記載した各成分を用い、常法に従って、乳化し、乳化組成物を調製した。
(Examples 1 to 8, Comparative Examples 1 to 4)
Each component shown in the table was emulsified according to a conventional method to prepare an emulsion composition.
(評価)
実施例及び比較例で調製した乳化組成物について以下の評価を行った。評価結果は表1に記載した。
(evaluation)
The emulsion compositions prepared in the Examples and Comparative Examples were evaluated as follows. The evaluation results are shown in Table 1.
(1)乳化状態
各実施例及び各比較例の乳化組成物を、ビーカーに入れた水の中に滴下し、分散しなければ油中水型の乳化状態(W/O)、分散すれば水中油型の乳化状態(O/W)と判定した)。
(1) Emulsified state The emulsified compositions of each example and each comparative example were dropped into water in a beaker. If not dispersed, water-in-oil emulsified state (W/O); if dispersed, water-in-oil emulsified state. (judged to be in an oil-type emulsified state (O/W)).
(2)粘度
各実施例及び各比較例の乳化組成物について、25℃にてB型粘度計(東機産業株式会社製、型番TVB-10)を用い測定した。
(2) Viscosity The emulsion compositions of each Example and each Comparative Example were measured at 25° C. using a B-type viscometer (manufactured by Toki Sangyo Co., Ltd., model number TVB-10).
(3)安定性
各実施例及び比較例の乳化組成物50gをスクリュー管に充填し、密封した状態で、室温(25℃)で1週間保管した。保管後の各乳化組成物について、下記基準に従って評価した。
(3) Stability 50 g of the emulsion composition of each Example and Comparative Example was filled into a screw tube and stored in a sealed state at room temperature (25° C.) for one week. Each emulsion composition after storage was evaluated according to the following criteria.
(判定基準)
〇(良好):分離が認められなかった。
×(不良):分離が認められた。
(Judgment criteria)
○ (Good): No separation was observed.
× (Poor): Separation was observed.
(4)クレンジング力(メイクアップ化粧料の除去力)
市販のウォータープルーフマスカラを人工皮膚(商品名「バイオスキンプレート」、白色、株式会社ビューラックス製)に塗布し、25℃の環境下で3時間放置した後、評価に用いた。実施例及び比較例の各乳化組成物約3gをコットン(目付130g/m2)に含浸させ、上記マスカラを塗布した人工皮膚を10往復擦り、マスカラの除去度合を目視にて観察し、以下の基準で評価した。
(判定基準)
○(良好):マスカラが完全に除去された。
×(不良):マスカラが残存していた。
(4) Cleansing power (ability to remove makeup cosmetics)
A commercially available waterproof mascara was applied to artificial skin (product name "Bio Skin Plate", white, manufactured by Bealux Co., Ltd.) and left for 3 hours in an environment of 25° C. before being used for evaluation. Approximately 3 g of each emulsion composition of the Examples and Comparative Examples was impregnated into cotton (basis weight 130 g/ m2 ), and the artificial skin coated with the mascara was rubbed back and forth 10 times, and the degree of mascara removal was visually observed and evaluated according to the following criteria.
(Judgment criteria)
◯ (Good): Mascara was completely removed.
× (bad): Mascara remained.
表1に示された結果から、各実施例の乳化組成物は、何れも油中水型乳化状態を示し、低粘度で、優れた安定性とクレンジング力を示した。一方、含有量合計(A1+A2)について本発明の範囲の下限未満となる比較例1では高粘度でクレンジング力に劣るものであり、質量割合(A1/(A1+A2))について本発明の範囲の下限未満となる比較例2では、水中油型乳化状態を示しクレンジング力に劣るものであり、質量割合(A1/(A1+A2))について本発明の範囲の上限超となる比較例3、及び、合計の含有量(A1+A2)について本発明の下限未満となる比較例4では、水中油型乳化状態を示し安定性とクレンジング力に劣るものであった。なお、各実施例の乳化組成物は、「(4)クレンジング力(メイクアップ化粧料の除去力)」の評価において、コットンへの含浸性が良好で、使用性に優れるものであった。 From the results shown in Table 1, the emulsion compositions of each example all exhibited a water-in-oil emulsion state, had low viscosity, and exhibited excellent stability and cleansing power. On the other hand, Comparative Example 1, in which the total content (A1+A2) is less than the lower limit of the range of the present invention, has a high viscosity and poor cleansing power, and the mass ratio (A1/(A1+A2)) is less than the lower limit of the range of the present invention. In Comparative Example 2, it shows an oil-in-water emulsion state and has poor cleansing power, and in Comparative Example 3, the mass ratio (A1/(A1 + A2)) exceeds the upper limit of the range of the present invention, and the total content Comparative Example 4, in which the amount (A1+A2) was less than the lower limit of the present invention, showed an oil-in-water emulsion state and was inferior in stability and cleansing power. In the evaluation of "(4) Cleansing power (removal power of makeup cosmetics)", the emulsified compositions of each Example had good impregnability into cotton and excellent usability.
