【発明の属する技術分野】
本発明は、エアゾール型頭髪化粧料で容器のノズルから泡沫状に吐出し、あるいは吐出後に泡状になり、適度な気泡性と泡もちを有する泡沫状頭髪化粧料に関し、更に詳細には、気泡性(泡のふくらみ)が良好であるために使用性(使いやすさ)が良く、優れた毛髪セット効果を有しながらもべたつきやフレーキング(皮膜形成樹脂の剥離)を生じることなく、毛髪を適度に束ね、しかも指通りが良く、かつ、皮膜形成樹脂の膜の適度な保湿性により、毛髪にごわつきのない、しなやかな感触を与える泡沫状頭髪化粧料に関するものである。
【0002】
【従来の技術】
整髪料は、毛髪を思い通りの形状や感触にして整え維持する目的で使用され、霧状、液状、ジェル状、泡沫状等様々な形態のものがある。これらはアニオン性、カチオン性、ノニオン性、両性等各種の皮膜形成樹脂を水、低級アルコール等の溶媒に溶解したものが骨格となっており、これに活性剤、油剤、増粘剤、場合により噴射剤等を適宜配合して用いられている。これら様々な形態の整髪料のうち、特に泡沫状のものは泡が毛髪になじみやすく、頭皮に付着しにくいため使いやすいので広く使用されている。
【0003】
【発明が解決しようとする課題】
しかしながら、このような整髪料は、毛髪のセット効果を高めるために皮膜形成樹脂を多量に配合すると、整髪の際の指通りを悪化させたり、乾いた後に髪のごわつきや皮膜形成樹脂の剥離(フレーキング)を生じることがあった。また、泡沫状頭髪化粧料においては皮膜形成樹脂を高配合することにより気泡性(泡のふくらみ)が低下することがあった。このような問題を解決するために、多価アルコールやその誘導体、ラノリン、エステル類等各種添加剤の配合による改良が試みられたが、添加に伴ってセット効果が低下してしまい、整髪料として満足のいくものが得られない場合や気泡性を損なうことがあった。同様に、皮膜形成樹脂の配合量を低減しても、毛髪の感触や気泡性は向上するが、セット効果の面で満足のいくものが得られなかった。そこで、泡沫状頭髪化粧料において、気泡性(泡のふくらみ)が良好であるために使用性(使いやすさ)が良く、優れた毛髪セット効果を有しながらもべたつきやフレーキング(皮膜形成樹脂の剥離)を生じることなく、毛髪を適度に束ね、しかも指通りが良く、かつ、皮膜形成樹脂の膜の適度な保湿性により、毛髪にごわつきのない、しなやかな感触を付与することのできる新しい泡沫状頭髪化粧料の開発が望まれていた。
【0004】
【課題を解決するための手段】
このような事情に鑑み、上記欠点を克服すべく鋭意研究を行った結果、皮膜形成樹脂と糖アルコールを組み合わせてなる原液と噴射剤を用いた泡沫状頭髪化粧料が、気泡性(泡のふくらみ)が良好であるために使用性(使いやすさ)が良く、優れた毛髪セット効果を有しながらもべたつきやフレーキング(皮膜形成樹脂の剥離)を生じることなく、毛髪を適度に束ね、しかも指通りが良く、かつ、皮膜形成樹脂の膜の適度な保湿性により、毛髪にごわつきのない、しなやかな感触を与える泡沫状頭髪化粧料が得られることを見いだし、この知見に基づいて本発明を完成した。
【0005】

BACKGROUND OF THE INVENTION
The present invention relates to a foam-type hair cosmetic that is discharged from a nozzle of a container with an aerosol-type hair cosmetic or foamed after discharge, and has a suitable cellularity and foaminess. It has good usability (ease of use) because it has good properties (bubble swell), and has excellent hair setting effect, yet it does not cause stickiness or flaking (peeling of film-forming resin). The present invention relates to a foam-like hair cosmetic that is moderately bundled and that is easy to finger, and has a soft feel without causing the hair to be stiff due to the appropriate moisture retention of the film of the film-forming resin.
[0002]
[Prior art]
Hair styling agents are used for the purpose of adjusting and maintaining the hair in the desired shape and feel, and have various forms such as mist, liquid, gel, and foam. These are skeletons made by dissolving various film-forming resins such as anionic, cationic, nonionic, and amphoteric in a solvent such as water and lower alcohol, and this contains activators, oils, thickeners, and in some cases. A propellant or the like is appropriately blended and used. Of these various forms of hair styling products, especially foamy ones are widely used because the bubbles are easy to use because they are easy to adjust to the hair and do not adhere to the scalp.
[0003]
[Problems to be solved by the invention]
However, when such a hairdressing agent contains a large amount of a film-forming resin in order to enhance the hair setting effect, the fingering during hairstyling deteriorates or the hair becomes stiff after drying and the film-forming resin peels off ( Flaking) may occur. In addition, in foamy hair cosmetics, foaming (bubble swelling) may be lowered by adding a film-forming resin in a high amount. In order to solve such problems, attempts have been made to improve by blending various additives such as polyhydric alcohols and their derivatives, lanolin, esters, etc. In some cases, a satisfactory product could not be obtained, and the bubble property was impaired. Similarly, even if the blending amount of the film-forming resin is reduced, the feel and foaming properties of the hair are improved, but a satisfactory one in terms of the set effect cannot be obtained. Therefore, in foamy hair cosmetics, the foamability (bubble swell) is good, so the usability (ease of use) is good, and the sticky hair and flaking (film-forming resin) have an excellent hair setting effect. Newly capable of giving a supple feel that the hair is properly bundled and finger-free, and that the film of the film-forming resin is moderately moisturized without causing the hair to become stiff. Development of foamy hair cosmetics has been desired.
[0004]
[Means for Solving the Problems]
In view of such circumstances, as a result of earnest research to overcome the above-mentioned drawbacks, a foamy hair cosmetic using a stock solution and a propellant combining a film-forming resin and a sugar alcohol is ) Has good usability (ease of use), and has an excellent hair setting effect, but without causing stickiness and flaking (peeling of the film-forming resin), the hair is appropriately bundled, and It has been found that a foamy hair cosmetic that gives a smooth feel without causing the hair to become stiff and smooth due to the appropriate moisture retention of the film of the film-forming resin is obtained, and the present invention is based on this finding. completed.
[0005]
That is, the present invention is a foamy hair cosmetic characterized by comprising a stock solution containing a film-forming resin and a sugar alcohol and a propellant.
[0006]
