Description
本発明は、油中水型乳化化粧料に関し、良好な乳化状態を有し、温度や経時による変化が少なく、塗布時に肌の上でみずみずしく、のびが良い油中水型乳化化粧料に関する。 TECHNICAL FIELD The present invention relates to a water-in-oil emulsified cosmetic, which relates to a water-in-oil emulsified cosmetic having a good emulsified state, little change due to temperature and time, fresh on the skin at the time of application, and good spreading.
従来、油中水型乳化化粧料は、固形・半固形の油分を配合して外相（油相）の粘度を高くすることにより、安定性の高いものを得ていたため、油っぽく、べたつく使用感であった。このため、多くの水相を含有し、かつ油相中の固形・半固形油分を大幅に少なくすることにより使用感を改善した乳化方法が開発された。（特許文献１及び２） In the past, water-in-oil emulsified cosmetics were blended with solid and semi-solid oils to increase the viscosity of the outer phase (oil phase), resulting in a highly stable product. It was a feeling. Therefore, an emulsification method has been developed that contains a large amount of an aqueous phase and has improved usability by significantly reducing the amount of solid / semi-solid oil in the oil phase. (Patent Documents 1 and 2)
さらに、最近では特許文献３〜６のように吸油性の高い粉体でありかつ粒径の異なる粉体を特定の重量比で混合した粉体を使用した乳化化粧料や、特許文献７のようにカルボキシビニルポリマーを疎水化シリカ及び／又はオルガノポリシロキサンエラストマー球状粉体と特定の重量比で混合した乳化化粧料が開発されている。 Furthermore, recently, emulsified cosmetics using powders that are highly oil-absorbing and mixed with powders having different particle sizes at a specific weight ratio, as in Patent Documents 3 to 6, and Patent Document 7 In addition, emulsified cosmetics in which carboxyvinyl polymer is mixed with hydrophobic silica and / or organopolysiloxane elastomer spherical powder at a specific weight ratio have been developed.
しかしながら、上記のいずれの化粧料も、肌への塗布時ののびの悪さ、さっぱり感の不足という点に関しては改善されているものの、乳化の安定性及び塗布時のみずみずしさに関してはいまだに不十分である。みずみずしさとは、化粧料を肌に塗布した時に感じる水分の潤い感を意味する。 However, although any of the above-mentioned cosmetics has been improved in terms of poor spreading when applied to the skin and lack of refreshing feeling, the stability of emulsification and freshness at the time of application are still insufficient. is there. Mizumizushi means a moist feeling when applying cosmetics to the skin.

（調製方法）
処方例１及び処方例１０の処方に従い（ａ）、（ｃ）、（ｄ）、（ｅ）を油相として、（ｂ）、（ｆ）、（ｇ）を水相として各々混合攪拌した。次いで、油相を攪拌機で攪拌しながら水相を徐々に添加し、ホモミキサーにて１５分間攪拌を続け調製した。
As Example 5, a W / O type cream foundation was prepared based on the formulations of Formulation Example 1 and Formulation Example 10 of the W / O cream foundation shown in Table 5, and the feeling of use and the emulsion stability were evaluated. . The results are also shown in Table 5.
(Preparation method)
According to the formulations of Formulation Example 1 and Formulation Example 10, (a), (c), (d) and (e) were used as the oil phase, and (b), (f) and (g) were mixed and stirred as the aqueous phase. Next, the water phase was gradually added while stirring the oil phase with a stirrer, and the mixture was continuously stirred for 15 minutes with a homomixer.
表１の結果から明らかなように、比較例１は疎水化シリカが配合されていないために、処方例１と比較して乳化安定性が十分でない。比較例２は水溶性高分子が配合されていないために、処方例１と比較して塗布時のみずみずしさ、のびの軽さが十分でない。また、比較例３はＨＬＢ値７以下の親油性界面活性剤が配合されていないために、４０℃での過酷条件では乳化安定性がやや十分でない傾向がある。 As is clear from the results in Table 1, since Comparative Example 1 does not contain hydrophobized silica, the emulsion stability is not sufficient as compared with Formulation Example 1. Since Comparative Example 2 does not contain a water-soluble polymer, compared with Formulation Example 1, the freshness and the lightness of spreading are not sufficient only during application. Further, since Comparative Example 3 does not contain a lipophilic surfactant having an HLB value of 7 or less, the emulsification stability tends to be slightly insufficient under severe conditions at 40 ° C.
これらに対して処方例１は、肌上でののびが軽く、べたつきの無い、みずみずしい使用感で、乳化安定性に優れたものである。 On the other hand, Formulation Example 1 is light on the skin, has no stickiness, has a fresh feeling of use, and has excellent emulsification stability.
表２の結果から、処方例１及び処方例２は疎水化シリカの平均一次粒子径が５ｎｍ〜２０ｎｍのため、使用感、乳化安定性が優れており、処方例３は疎水化シリカの平均一次粒子径が２０ｎｍより大きいため、処方例１及び処方例２と比較して乳化安定性の面で差がある。 From the results of Table 2, Formulation Example 1 and Formulation Example 2 are excellent in feeling of use and emulsion stability because the average primary particle size of hydrophobic silica is 5 nm to 20 nm, and Formulation Example 3 is an average primary of hydrophobic silica. Since the particle size is larger than 20 nm, there is a difference in emulsion stability as compared with Formulation Example 1 and Formulation Example 2.
表３の結果から、処方例１、処方例５及び処方例６と比較して、処方例４及び処方例７は油に対する疎水化シリカの割合が重量比で３％未満のため、乳化安定性がやや十分でない傾向がある。 From the results of Table 3, compared to Formulation Example 1, Formulation Example 5 and Formulation Example 6, Formulation Example 4 and Formulation Example 7 have an emulsion stability because the ratio of hydrophobized silica to oil is less than 3% by weight. There is a tendency not to be enough.
表４の結果から、処方例１と比較して処方例８は、水に対する水溶性高分子の割合が重量比で０．２％未満のため、みずみずしさの面でやや差があり、また、処方例９は水に対する水溶性高分子の割合が重量比で０．２％以上であるが、肌上でのべたつきをやや感じる傾向がある。 From the results of Table 4, compared to Formulation Example 1, Formulation Example 8 is slightly different in terms of freshness because the ratio of the water-soluble polymer to water is less than 0.2% by weight, In Formulation Example 9, the ratio of the water-soluble polymer to water is 0.2% or more by weight, but there is a tendency to feel a little stickiness on the skin.
表５の結果から、化粧品へ配合される代表的な水溶性高分子のうち、処方例１のキサンタンガムの方が、処方例１０のカルボキシビニルポリマーよりも、使用感のみずみずしさ、のび、乳化安定性に優れていることがわかる。 From the results of Table 5, among typical water-soluble polymers to be blended into cosmetics, the xanthan gum of Formulation Example 1 has a feeling of use, spread, and emulsion stability more than the carboxyvinyl polymer of Formulation Example 10. It turns out that it is excellent in property.
