特許法第30条第2項適用 〔発行者名〕 The International Federation of Societies of Cosmetic Chemists 〔刊行物名〕 29th International Federation of Societies of Cosmetic Chemists(IFSCC)Congress ORLANDO FLORIDA 2016 ORIGINAL PROGRAM 〔発行年月日〕 平成28年10月30日Patent Law Article 30 Paragraph 2 Applicable [Publisher Name] The International Federations of Floridas of Cosmetic Chemists [Publication Name] 29th International Federation of Florida October 30, 2016

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 emulsified cosmetic.

従来、日焼け止めなどの油中水型乳化化粧料では、高い化粧持ち効果や耐汗性が求められるため、シリコーン油により表面処理された粉体が多く使用されている。しかし、シリコーン油により表面処理された粉体を配合した油中水型乳化化粧料は、その高い化粧持ち効果ゆえに、石鹸などによる通常の水性洗浄では洗い落とすことが困難であり、専用のオイルクレンジング剤を使用することが必要であった。 Conventionally, in water-in-oil emulsified cosmetics such as sunscreens, powders surface-treated with silicone oil are often used because they are required to have a high long-lasting effect and sweat resistance. However, water-in-oil emulsified cosmetics containing powders surface-treated with silicone oil are difficult to wash off with ordinary water-based washing with soap, etc. due to their high cosmetic retention effect, and are dedicated oil cleansing agents. It was necessary to use.

そこで、近年では、N-アシルアミノ酸により表面処理された粉体を用いることにより洗浄性を改善することが提案されている(特許文献1)。 Therefore, in recent years, it has been proposed to improve the detergency by using a powder surface-treated with N-acylamino acid (Patent Document 1).

特許文献1では、N-アシルアミノ酸により表面処理された粉体を用いた油中水型乳化化粧料の洗浄性について、パネラーの官能により評価し、洗浄性が改善されたことを確認している。しかし、実際には目には見えない洗浄残りがあり、その洗浄性は依然として不十分であった。 In Patent Document 1, the detergency of a water-in-oil emulsified cosmetic using a powder surface-treated with N-acylamino acid is evaluated by the sensory function of a panelist, and it is confirmed that the detergency is improved. .. However, in reality, there was an invisible cleaning residue, and the cleaning property was still insufficient.

本発明は、上記従来技術の諸問題を解消するためになされたものであり、化粧持ち効果を維持しつつ、洗浄性を向上させた油中水型乳化化粧料を提供することを目的とする。 The present invention has been made to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide a water-in-oil emulsified cosmetic having improved detergency while maintaining a makeup-retaining effect. ..

本発明者らは、鋭意研究の結果、N-アシルアミノ酸により表面処理された粉体を、シリコーン系界面活性剤以外の界面活性剤により予め分散して配合することにより、化粧持ち効果を維持しつつ、洗浄性を向上できることを見出した。 As a result of diligent research, the present inventors maintain the cosmetic lasting effect by pre-dispersing and blending the powder surface-treated with N-acylamino acid with a surfactant other than the silicone-based surfactant.

各試料を肌に塗布し、20分後、石鹸を用いて水洗洗浄を行った。洗浄後の肌について、UVGL-58 Handheld UV Lamp 365nm(UVP,Inc.製)またはマクベス標準光源装置(X-rite社製)のUV光源(F30T8 BLB 365nm)により紫外線を照射して反射光を確認することにより、洗い残しの有無を評価した。
(評価基準)
○: 完全に洗浄できた
△: 洗浄不足あり
×: 洗い落とせない
d. Detergency (evaluation method)
Each sample was applied to the skin, and after 20 minutes, it was washed with water using soap. After washing, UVGL-58 Handheld UV Lamp 365nm (UVP, Inc.) or Macbeth standard light source device (X-rite) UV light source (F30T8 BLB 365nm) is used to irradiate the skin with ultraviolet rays to check the reflected light. By doing so, the presence or absence of unwashed residue was evaluated.
(Evaluation criteria)
○: Completely washed △: Insufficient cleaning ×: Cannot be washed off

[結果]
表1~3の結果から明らかなように、本発明の実施品である実施例1~3および5~14は、優れた洗浄性を有するため、石鹸などによる通常の水性洗浄によっても、洗い残しなく容易かつ十分に洗浄、除去することが可能であり、高い化粧持ち効果と高い洗浄性を両立した優れた日焼け止め化粧料であった。一方、オレイン酸またはステアリン酸を構成脂肪酸とするポリグリセリン脂肪酸エステルおよびソルビタン脂肪酸エステル以外の界面活性剤を分散剤として使用した比較例1~4は、洗浄性が低かった。
[result]
As is clear from the results in Tables 1 to 3, Examples 1 to 3 and 5 to 14 which are the products of the present invention have excellent detergency, and therefore are left unwashed even by ordinary water-based washing with soap or the like. It was an excellent sunscreen cosmetic that could be easily and sufficiently washed and removed without any problems, and had both a high makeup-retaining effect and a high detergency. On the other hand, Comparative Examples 1 to 4 in which a surfactant other than the polyglycerin fatty acid ester and the sorbitan fatty acid ester having oleic acid or stearic acid as constituent fatty acids was used as a dispersant had low detergency.

An oily component, a dispersant (corresponding to the component (b) of the present invention), an inorganic pigment (corresponding to the component (a) of the present invention), and an ultraviolet scattering agent (corresponding to the component (a) of the present invention) are mixed in advance and pulverized. Then, an emulsifier, an antioxidant, and an elastic powder were added and uniformly dispersed to obtain an oil phase component. Next, an aqueous phase component in which an aqueous component, a moisturizer, and a preservative were uniformly mixed was slowly added to the above oil phase component and uniformly dispersed with a homomixer to obtain a foundation.
(Makeup base)
An oily component, a dispersant (corresponding to the component (b) of the present invention), an inorganic pigment (corresponding to the component (a) of the present invention), and an ultraviolet scattering agent (corresponding to the component (a) of the present invention) are mixed in advance and pulverized. Then, an emulsifier, an ultraviolet absorber, an antioxidant, a gel-like composition, and an elastic powder were added and uniformly dispersed to obtain an oil phase component.

[結果]
表4および5の結果から明らかなように、本発明の実施品である実施例17~22は、優れた洗浄性を有するため、石鹸などによる通常の水性洗浄によっても、洗い残しなく容易かつ十分に洗浄、除去することが可能であり、高い化粧持ち効果と高い洗浄性を両立した優れた日焼け止め化粧料であった。一方、粉体成分である着色顔料および紫外線散乱剤の表面処理をシリコーンにより行った比較例6~9は、洗浄性が低かった。
[result]
As is clear from the results of Tables 4 and 5, since Examples 17 to 22, which are the products of the present invention, have excellent detergency, they are easily and sufficiently unwashed even by ordinary water-based washing with soap or the like. It was an excellent sunscreen cosmetic that could be washed and removed, and had both a high long-lasting effect and high detergency. On the other hand, Comparative Examples 6 to 9 in which the surface treatment of the color pigment and the ultraviolet scattering agent, which are powder components, were performed with silicone, had low detergency.

このように、N-アシルアミノ酸またはその塩により表面処理された粉体と、オレイン酸またはステアリン酸を構成脂肪酸とするポリグリセリン脂肪酸エステルおよびソルビタン脂肪酸エステルからなる群から選択される界面活性剤とを予め混合した後、油相成分に分散させ、さらにこれを水相成分に徐添して乳化させて製造することにより、化粧持ち効果を維持しつつ、洗浄性を向上させた油中水型乳化化粧料が得られることが明らかになった。 As described above, the powder surface-treated with N-acylamino acid or a salt thereof and the surfactant selected from the group consisting of polyglycerin fatty acid ester and sorbitan fatty acid ester having oleic acid or stearic acid as a constituent fatty acid are prepared. After mixing in advance, it is dispersed in the oil phase component, and further gradually added to the aqueous phase component to emulsify it. It became clear that cosmetics could be obtained.
