【発明の属する技術分野】
本発明は、染毛処理した毛髪に対して退色及び変色防止効果に優れ、泡立ちが良好である染毛処理した毛髪用シャンプー組成物に関する。
【0002】
【従来の技術】
近年、染毛に対する消費者意識の高まりに伴い、様々な剤型や色の染毛剤が多数市販されており、幅広い年齢層に染毛剤が利用されるようになった。これら染毛剤使用者の要望としては染毛処理後の毛髪の色持ちを向上させることが挙げられる。染毛処理した毛髪の退色や変色は酸化染料や酸性染料の構造変化による変色や毛髪からの離脱による色抜けに起因している。
【0003】
従来から、これらの変色や退色を防ぐ方法として、染毛剤組成物中に堅牢性を向上させるための成分を配合したり(特開昭61−218512号公報、特開平4−360817号公報等)、染毛前後に使用するケア剤を提案する(特開平6−92824号公報等)等の試みが多数なされているが、使用するシャンプーの種類によっては、十分満足される効果が得られない場合があった。このように変色や退色に及ぼすシャンプーによる影響は大きく、変色や退色し難いシャンプーを開発することが切望されているのが現状である。このようなニーズに対応して、pHを酸性領域に調整したり、特定の界面活性剤を用いたシャンプー等が提案されている(特開平7−233033号公報、特開2001−240517号公報等)。しかしながら、これら従来提案されているシャンプーは、使用している界面活性剤が、元来起泡性が弱いものや、酸性領域、特にpH6以下で起泡性が十分でないもの、また、高価であるため汎用品としてのシャンプーには少量しか配合できないもの等が多く、泡立ちの面において十分に満足されるものではなかった。
【0004】
【発明が解決しようとする課題】

BACKGROUND OF THE INVENTION
The present invention relates to a shampoo composition for hair that has been dyed and has excellent fading and discoloration prevention effects on hair that has been dyed and has good foaming.
[0002]
[Prior art]
In recent years, with increasing consumer awareness of hair dyeing, a large number of hair dyes of various dosage forms and colors are commercially available, and hair dyes have been used for a wide range of ages. As a request of these hair dye users, it is possible to improve the color retention of the hair after the hair dyeing treatment. The discoloration and discoloration of the hair dyed hair is caused by discoloration due to structural change of the oxidation dye or acid dye or color loss due to separation from the hair.
[0003]
Conventionally, as a method for preventing these discoloration and fading, a component for improving fastness is blended in a hair dye composition (Japanese Patent Laid-Open Nos. 61-218512, 4-360817, etc.) ), And many attempts have been made to propose a care agent used before and after hair dyeing (JP-A-6-92824, etc.), but depending on the type of shampoo used, a sufficiently satisfactory effect cannot be obtained. There was a case. In this way, the influence of shampoos on discoloration and fading is great, and there is an urgent need to develop shampoos that are difficult to discolor and discolor. In response to such needs, there have been proposed shampoos or the like that adjust the pH to an acidic region or use a specific surfactant (Japanese Patent Laid-Open Nos. 7-233303 and 2001-240517). ). However, in these conventionally proposed shampoos, the surfactants used are inherently weak in foaming properties, are in an acidic region, particularly those having a foaming property of pH 6 or lower, and foaming properties are expensive. For this reason, many shampoos as general-purpose products can be blended in only a small amount, and are not fully satisfied in terms of foaming.
[0004]
[Problems to be solved by the invention]
In light of the above-described conventional technology, an object of the present invention is to provide a shampoo composition for hair that has been dyed and has excellent effects of preventing fading and discoloration and good foaming.
