Summary: | PROBLEM TO BE SOLVED: To provide a stable composition comprising poly-ion complex particles, for example, stable dispersions, to provide methods of readily preparing a comparatively thick film made of poly-ion complex particles, and to provide comparatively thick films made of poly-ion complex particles.SOLUTION: The present invention relates to a composition which comprises (a) at least one particle containing at least one cationic polymer, at least one anionic polymer, and at least one non-polymer acid with two or more pKa values or a salt thereof, and (b) at least one physiologically acceptable volatile medium. The composition according to the invention is stable and can have various cosmetic functions. The composition according to the invention, for example, can prepare a film which can have cosmetic effects, such as absorbing or adsorbing a bad smell, changing the appearance of a keratin substrate such as the skin and the like, changing the feel of a keratin substrate and/or protecting a keratin substrate from, for example, dirt or contaminants, and the like.SELECTED DRAWING: None
【課題】ポリイオンコンプレックス粒子を含む安定な組成物、例えば安定な分散体を提供すること、ポリイオンコンプレックス粒子製の比較的厚い皮膜を容易に調製することができる方法を提供すること、及びポリイオンコンプレックス粒子製の比較的厚い皮膜を提供すること。【解決手段】本発明は、(a)少なくとも1種のカチオン性ポリマーと、少なくとも1種のアニオン性ポリマーと、少なくとも1種の2つ以上のpKa値を有する非ポリマー酸又はその塩とを含む少なくとも1種の粒子、及び(b)少なくとも1種の生理学的に許容される揮発性媒体を含む本発明による組成物に関する。本発明による組成物は、安定であり、多様な美容機能を有することができる。例えば、本発明による組成物は、悪臭を吸収若しくは吸着する、皮膚等のケラチン基材の外観を変化させる、ケラチン基材の触感を変化させる、及び/又は例えば汚れ若しくは汚染物質からケラチン基材を保護する等の美容効果を有することができる皮膜を調製することができる。【選択図】なし |
