Description
本発明は、泡の弾力に優れるとともに、非常に低湿度の環境下でも、乾燥後の頭皮のしっとり感とその持続性にも優れる毛髪洗浄剤組成物に関する。 The present invention relates to a hair cleansing composition which is excellent in elasticity of foam and excellent in moist feeling of scalp after drying and its persistence even in a very low humidity environment.
毛髪洗浄剤の界面活性剤成分として、洗浄力の高さや配合のし易さから、ポリオキシエチレンアルキルエーテル硫酸塩が広く使用されており、数多くの配合処方が提案されている。中でも、泡のクリーミーさや弾力性などの泡質を高めたり、毛髪へのダメージをよりマイルドにしたりするために、アミノ酸系界面活性剤と組み合わせたものが多く知られている。例えば、特許文献１には、ポリオキシエチレンラウリルエーテル硫酸ナトリウムとアシルアラニン塩と両性界面活性剤とカチオン化ポリマーを組み合わせた組成物が提案されている。
しかしながら、この組成物は洗髪時に弾力のある泡を与えるものの、毛髪を乾燥させた後に頭皮にややつっぱり感を生じ、頭皮のしっとり感が十分ではなかった。
As a surfactant component of a hair cleansing agent, polyoxyethylene alkyl ether sulfate is widely used because of its high detergency and ease of compounding, and many compounding formulations have been proposed. Above all, many combinations with an amino acid-based surfactant are known in order to improve foam quality such as foam creaminess and elasticity, and to make hair damage milder. For example, Patent Document 1 proposes a composition in which sodium polyoxyethylene lauryl ether sulfate, an acyl alanine salt, an amphoteric surfactant, and a cationized polymer are combined.
However, although this composition gives an elastic foam at the time of washing the hair, the scalp has a slightly firm feeling after drying the hair, and the scalp does not have a sufficient moist feeling.
そのため、頭皮のしっとり感を向上させるための配合処方がいくつか提案されている。例えば、特許文献２には、ポリオキシエチレンラウリルエーテル硫酸ナトリウムとアシルグルタミン酸塩とカチオン化ポリマーを組み合わせた組成物が提案されている。この組成物は乾燥後の頭皮にしっとり感を与えることができる。
さらに、頭皮のしっとり感が持続するような処方も提案されており、例えば、特許文献３には、ポリオキシエチレンラウリルエーテル硫酸ナトリウムと水酸基を構造中に持つアシルヒドロキシアルキルβアラニン塩と両性界面活性剤を含有する組成物が提案されている。
しかしながら、これらの組成物は、乾燥後の頭皮のしっとり感とその持続性も向上させてはいるが、湿度の低い冬場の乾燥時期にはこれらの効果は必ずしも十分とはいえなかった。そのため、非常に低湿度で乾燥した環境下でも、乾燥後の頭皮に十分なしっとり感を与え、またそのしっとり感が持続できるような毛髪洗浄剤が求められていた。
For this reason, several compounding formulations have been proposed for improving the moist feeling of the scalp. For example, Patent Document 2 proposes a composition in which sodium polyoxyethylene lauryl ether sulfate, an acyl glutamate, and a cationized polymer are combined. This composition can give a moist feeling to the scalp after drying.
Furthermore, a formulation that maintains the moist feeling of the scalp has also been proposed. For example, Patent Document 3 discloses sodium polyoxyethylene lauryl ether sulfate and an acylhydroxyalkyl β-alanine salt having a hydroxyl group in the structure and an amphoteric surfactant. Compositions containing agents have been proposed.
However, although these compositions have also improved the moist feeling of the scalp after drying and the durability thereof, these effects have not always been sufficient during the dry season in winter when the humidity is low. Therefore, there has been a demand for a hair cleansing agent which gives a sufficiently moist feeling to the scalp after drying even under an environment of very low humidity and which can maintain the moist feeling.
本発明は、泡の弾力に優れるとともに、非常に低湿度の環境下でも、乾燥後の頭皮のしっとり感とその持続性にも優れる毛髪洗浄剤組成物を提供することを目的とする。 An object of the present invention is to provide a hair cleansing composition which is excellent in elasticity of foam and excellent in moist feeling of scalp after drying and its persistence even in an environment of very low humidity.
本発明者らは、上記課題を解決するために鋭意検討を行った結果、アミノ酸系界面活性剤であるアシルヒドロキシアルキルアラニン塩、エーテルサルフェート型陰イオン性界面活性剤、グリコール酸またはその塩を含有する毛髪洗浄剤組成物において、これら成分の内、アシルヒドロキシアルキルアラニン塩とエーテルサルフェート型陰イオン性界面活性剤とを所定の割合で含有させることによって、泡の弾力に優れるとともに、非常に低湿度の環境下でも、乾燥後の頭皮のしっとり感とその持続性にも優れることを見出し、本発明を完成するに至った。 The present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, containing an amino acid-based surfactant acylhydroxyalkylalanine salt, an ether sulfate-type anionic surfactant, glycolic acid or a salt thereof. In a hair cleansing composition to be used, an acylhydroxyalkylalanine salt and an ether sulfate type anionic surfactant are contained in a predetermined ratio among these components, so that the foam has excellent elasticity and very low humidity. It was also found that the scalp after drying was excellent in moist feeling and its persistence even under the above environment, and the present invention was completed.

In Comparative Example 2, since the component (b) was not contained, the elasticity of the foam was poor.
In Comparative Example 3, since the mass ratio ((a) / (b)) exceeded the upper limit of the specified range of the present invention, the moist feeling of the scalp and its persistence were good, but the elasticity of the foam was poor. Was inferior.
On the other hand, in Comparative Example 4, since the mass ratio ((a) / (b)) was less than the lower limit of the range specified in the present invention, the elasticity of the foam was inferior, and the moist feeling after drying and its persistence were observed. Was inadequate.
In Comparative Example 5, the foam had good elasticity because it contained sodium lauroylmethylalanine instead of the component (a), but both the moist feeling of the scalp after drying and its persistence were insufficient. there were.
In Comparative Example 6, since the component (c) was not contained, both the moist feeling of the scalp after drying and its persistence were insufficient.
