Abstract
Description
本発明は皮膚化粧料組成物に関し、特に、乳化安定性が良く、経時的に流動性の低下がなく、しっとり感およびしっとり感の持続力が高く、塗布時に厚みがあって塗り心地が良く、なおかつ皮膚へのなじみの良い皮膚化粧料組成物に関する。 The present invention relates to a skin cosmetic composition, in particular, has good emulsification stability, does not decrease in fluidity over time, has a high sustainability of moist feeling and moist feeling, is thick at the time of application, and is comfortable to apply. Moreover, the present invention relates to a skin cosmetic composition that is familiar to the skin.
従来、皮膚に塗布する化粧料組成物としては、化粧水、乳液、クリームなどが挙げられ、種々の検討がなされている。中でも乳液は化粧水よりもしっとり感やしっとり感の持続力が高いだけでなく、皮膚へのなじみやクリームよりもみずみずしい感触が求められる剤型である。乳液はしっとり感、しっとり感の持続力および皮膚へのなじみを高めるために多量の油性成分を乳化して含有する必要がある。しかし、乳液は流動性のある液状を維持しなければならないため、乳化安定性を維持することが困難である。その問題を解決するために、近年、特許文献１に開示されるように、高分子乳化剤の使用が検討されている。アクリル酸・メタクリル酸アルキル共重合体に代表される高分子乳化剤は種々の油剤を少量で安定に乳化することができるだけでなく、皮膚に塗布した際に、みずみずしい感触を得られる乳化剤である。 Conventionally, cosmetic compositions to be applied to the skin include cosmetic waters, milky lotions, creams, and the like, and various studies have been conducted. Among them, milky lotion is a dosage form that not only has a higher lasting moisturizing feeling and moisturizing feeling than lotion, but also needs to be familiar to the skin and feel fresher than cream. The milky lotion needs to emulsify and contain a large amount of oily component in order to enhance the moist feeling, the lasting moist feeling and the familiarity with the skin. However, it is difficult to maintain emulsion stability because the emulsion must maintain a fluid liquid state. In order to solve this problem, the use of a polymer emulsifier has been studied in recent years as disclosed in Patent Document 1. Polymer emulsifiers typified by acrylic acid / alkyl methacrylate copolymers are emulsifiers that not only can stably emulsify various oils with a small amount, but also give a fresh feel when applied to the skin.
しかしながら、特許文献１の技術で多量の油性成分を含有すると、油性成分の一部が乳化しきれず乳液の表面に油膜として残る場合や経時的に油滴として吐き出される場合がある。そこで、高分子乳化剤の含有量を増やして解決を試みるが、粘度が上昇し乳液の流動性を維持できなくなる場合や皮膚表面に膜を形成し、皮膚へのなじみが悪化する場合がある。上記問題を解決するため、高分子乳化剤の他に高級アルコールおよびノニオン性界面活性剤を併用した技術が開示されている（特許文献２）。 However, if a large amount of oily component is contained in the technique of Patent Document 1, a part of the oily component may not be completely emulsified and may remain as an oil film on the surface of the emulsion or may be discharged as oil droplets over time. Therefore, an attempt is made to solve the problem by increasing the content of the polymer emulsifier, but the viscosity may increase and the fluidity of the emulsion may not be maintained, or a film may be formed on the skin surface to deteriorate the compatibility with the skin. In order to solve the above problems, a technique in which a higher alcohol and a nonionic surfactant are used in combination with a polymer emulsifier is disclosed (Patent Document 2).
しかしながら、特許文献２の技術を用いた場合、高級アルコールやノニオン性界面活性剤により経時的に乳液の流動性が低下し、ボトルやポンプ等から出しにくくなる場合があった。また、使用感に関して高分子乳化剤は塗り広げるときにみずみずしい感触が得られる反面、塗布時の厚みがなく、塗り心地に物足りなさを感じることがあった。 However, when the technique of Patent Document 2 is used, the fluidity of the emulsion may decrease with time due to the higher alcohol or the nonionic surfactant, and it may be difficult to remove the emulsion from the bottle or pump. Further, regarding the feeling of use, the polymer emulsifier gives a fresh feeling when spread, but on the other hand, there is no thickness at the time of application, and the feeling of application may be unsatisfactory.
本発明者は、上記課題を解決するために鋭意検討した結果、（Ａ）アクリル酸・メタクリル酸アルキル共重合体、（アクリル酸ヒドロキシエチル／アクリロイルジメチルタウリンＮａ）コポリマーまたは（アクリロイルジメチルタウリンアンモニウム／ＶＰ）コポリマーから選ばれる１種以上、（Ｂ）有機塩または無機塩から選ばれる１種以上、（Ｃ）ＨＬＢが３．０〜５．０であるノニオン性界面活性剤、（Ｄ）２５℃で液状の油性成分、（Ｅ）２５℃でペースト状の油性成分、（Ｆ）セルロース誘導体を含有し、前記（Ａ）成分の含有量が０．１〜０．５質量％であり、前記（Ｂ）成分の含有量が０．０５〜０．５質量％であり、前記（Ｃ）成分の含有量が０．２〜１質量％であり、前記（Ｄ）成分の含有量が３〜１２質量％であり、前記（Ｅ）成分の含有量が０．１〜１質量％であり、前記（Ｆ）成分の含有量が０．１〜０．７質量％である皮膚化粧料組成物によれば、乳化安定性が良く、経時的な流動性の低下がなく、しっとり感およびしっとり感の持続力が高く、塗布時に厚みがあって塗り心地が良く、なおかつ皮膚へのなじみの良い皮膚化粧料組成物が得られることを見出し、本発明を完成するに至った。 As a result of diligent studies to solve the above problems, the present inventor (A) acrylic acid / alkyl methacrylate copolymer, (hydroxyethyl acrylate / acryloyldimethyltaurine Na) copolymer or (acryloyldimethyltaurinammonium / VP) ) One or more selected from copolymers, (B) one or more selected from organic or inorganic salts, (C) nonionic surfactant having an HLB of 3.0 to 5.0, (D) at 25 ° C.
