Description

頭皮用組成物、頭皮用化粧料及び頭皮用組成物の塗布方法Composition for scalp, cosmetics for scalp and method for applying composition for scalp
　本発明は、頭皮に塗布される頭皮用組成物に関する。また、本発明は、上記頭皮用組成物を用いた頭皮用化粧料、及び上記頭皮用組成物の塗布方法に関する。 The present invention relates to a composition for scalp applied to the scalp. The present invention also relates to a scalp cosmetic using the scalp composition and a method of applying the scalp composition.
　人の頭皮は、紫外線に晒されたり、洗髪による刺激を受けたり、ドライヤー乾燥による熱刺激を受けたりする。なかでも、ドライヤー乾燥では、頭皮から水分が蒸発しやすくなる。このように、人の頭皮は、日常生活における様々な外的要因によって、日々ダメージを受けている。また、頭皮は、顔などの他の部位の皮膚と比較して、より乾燥している状態にある。このため、頭皮のバリア機能は、大きく低下していることがある。 The human scalp is exposed to ultraviolet rays, is stimulated by washing hair, and is thermally stimulated by dryer drying. In particular, moisture drying from the scalp tends to evaporate with dryer drying. Thus, the human scalp is damaged daily by various external factors in daily life. In addition, the scalp is in a drier state compared to the skin of other parts such as the face. For this reason, the barrier function of the scalp may be greatly reduced.
　頭皮のバリア機能が低下すると、頭皮の硬化が進行するなどして、フケ、発赤、湿疹及びかゆみなどの頭皮のトラブルが発生しやすくなる。また、このような頭皮のトラブルは、頭髪のハリ及びコシを低下させたり、薄毛を進行させたりする可能性もある。 When the barrier function of the scalp is lowered, the scalp is hardened, and scalp troubles such as dandruff, redness, eczema and itching are likely to occur. In addition, such a scalp trouble may reduce the firmness and stiffness of the hair and may cause thinning of the hair.
　そこで、頭皮において、潤いを付与するための保湿ケアが望まれる。しかし、頭皮は、他の部位の皮膚と比べて、皮脂が多く存在する。このため、頭皮に通常の化粧水を塗布しても、保湿成分が十分に浸透し難く、頭皮に十分な潤いを付与することが困難である。 Therefore, moisturizing care for imparting moisture to the scalp is desired. However, the scalp is rich in sebum compared to other parts of the skin. For this reason, even if a normal lotion is applied to the scalp, it is difficult for the moisturizing component to penetrate sufficiently and it is difficult to impart sufficient moisture to the scalp.
　また、頭皮上には頭髪が存在するため、頭皮に化粧水（頭皮用組成物）を効率よく塗布することも困難である。 Also, since scalp hair is present on the scalp, it is difficult to efficiently apply lotion (scalp composition) to the scalp.
　このように、頭皮に適用される化粧水（頭皮用組成物）には幾つかの課題があり、その課題を解決する検討が行われている。下記の特許文献１～５には、頭皮用組成物が開示されている。 As described above, there are some problems in the lotion applied to the scalp (composition for scalp), and studies to solve the problems are being conducted. The following Patent Documents 1 to 5 disclose scalp compositions.
　下記の特許文献１には、保湿剤と、アデノシン類とを含む組成物が開示されている。 The following Patent Document 1 discloses a composition containing a humectant and adenosines.
　下記の特許文献２には、ユーカリエキスと、多価アルコールと、保湿剤及び抗炎症剤の内の少なくとも一方とを含む組成物が開示されている。 The following Patent Document 2 discloses a composition containing a eucalyptus extract, a polyhydric alcohol, and at least one of a humectant and an anti-inflammatory agent.
　下記の特許文献３には、抗炎症剤と、殺菌剤と、ポリエチレングリコールとを含む組成物が開示されている。 The following Patent Document 3 discloses a composition containing an anti-inflammatory agent, a bactericidal agent, and polyethylene glycol.
　下記の特許文献４には、有機カルボン酸又はその塩を含む組成物が開示されている。この組成物を水で２０重量倍に希釈したときの２５℃におけるｐＨは１～５である。 The following Patent Document 4 discloses a composition containing an organic carboxylic acid or a salt thereof. When this composition is diluted 20 times by weight with water, the pH at 25 ° C. is 1 to 5.

The scalp composition has a viscosity at 25 ° C. of 50 mPa · s or more and 600 mPa · s or less. By adopting the specific composition described above and controlling the viscosity within the above range, the scalp has improved permeability, adhesion, anti-dripping property, anti-stickiness, moisturizing properties, hair sharpness and stiffness. All the effects can be improved in a balanced manner.
　付着性をより一層良好にし、垂れ落ちを防止する観点からは、上記粘度は好ましくは８０ｍＰａ・ｓ以上である。べたつきをより一層防止する観点、及び吐出不良をより一層抑える観点からは、上記粘度は好ましくは５００ｍＰａ・ｓ以下である。 From the viewpoint of further improving adhesion and preventing dripping, the above viscosity is preferably 80 mPa · s or more. From the viewpoint of further preventing stickiness and further suppressing the discharge failure, the viscosity is preferably 500 mPa · s or less.

　本発明に係る頭皮用化粧料は、上述した頭皮用組成物と、ジェットスプレー型のトリガー容器又はジェットスプレー型のポンプ容器とを備える。上記トリガー容器又は上記ポンプ容器内に、上記頭皮用組成物が充填されている。 The scalp cosmetic according to the present invention includes the above-described scalp composition and a jet spray type trigger container or a jet spray type pump container. The scalp composition is filled in the trigger container or the pump container.
　本発明では、上記頭皮用組成物は、頭皮だけでなく、頭皮と頭髪との双方に塗布されてもよい。頭皮における浸透性、及び保湿性を高めることを目的としているので、またこの目的を高レベルで達成することを目的としているので、上記頭皮用組成物の吐出形態として、ジェットスプレー方式による吐出形態が採用されている。一般に、頭皮に適用することが意図されていない組成物や、整髪剤などの頭髪全体に適用することが意図されている組成物では、霧状に噴霧されるミスト方式による吐出形態が採用され、ジェットスプレー方式は、一般的に採用されないと思われる。 In the present invention, the composition for scalp may be applied not only to the scalp but also to both the scalp and the hair. Since it aims to increase the permeability and moisture retention in the scalp, and also aims to achieve this purpose at a high level, as a discharge form of the composition for scalp, there is a discharge form by a jet spray method. It has been adopted. In general, in a composition that is not intended to be applied to the scalp and a composition that is intended to be applied to the entire hair, such as a hair styling agent, a mist-type discharge form that is sprayed in a mist form is employed, The jet spray method seems not to be generally adopted.
　本発明に係る頭皮用組成物の塗布方法では、上述した頭皮用化粧料を用いて、ジェットスプレー方式により、上記頭皮用組成物を頭皮に吐出する。 In the method of applying the scalp composition according to the present invention, the scalp composition is discharged onto the scalp by the jet spray method using the above-described scalp cosmetic.
　ジェットスプレー方式における吐出では、例えば、上記頭皮用組成物は線状に吐出される。ジェットスプレー方式における吐出では、上記頭皮用組成物は、頭髪を突き抜けて頭皮に至りやすい。ジェットスプレー方式における吐出では、上記頭皮用組成物を水平方向に１回吐出したときに、吐出部から１０ｃｍの距離における吐出面積（吐出された頭髪用組成物の外周で囲まれた面積）が９ｃｍ２以下である。ジェットスプレー方式における吐出は、ミスト方式における吐出と異なる。ミスト方式における吐出では、組成物を水平方向に１回吐出したときに、吐出部から１０ｃｍの距離における吐出面積（吐出された頭髪用組成物の外周で囲まれた面積）は１００ｃｍ２を超える。ミスト方式における吐出では、広い面積に組成物が塗布される。ミスト方式における吐出では、組成物は、頭髪を突き抜けて頭皮に至りにくい。 In the ejection in the jet spray method, for example, the scalp composition is ejected linearly. In the jet spray method, the scalp composition tends to penetrate the hair and reach the scalp. In the discharge in the jet spray method, when the scalp composition is discharged once in the horizontal direction, the discharge area at a distance of 10 cm from the discharge portion (area surrounded by the outer periphery of the discharged hair composition) is 9 cm. 2 or less. The discharge in the jet spray method is different from the discharge in the mist method. In the discharge by the mist method, when the composition is discharged once in the horizontal direction, the discharge area (area surrounded by the outer periphery of the discharged hair composition) at a distance of 10 cm from the discharge portion exceeds 100 cm 2 . In discharging in the mist method, the composition is applied over a wide area. In the ejection by the mist method, the composition hardly penetrates the hair and reaches the scalp.
