　［制汗剤］

　本発明の制汗剤は、容器と、上述した制汗剤組成物とを備える。上記制汗剤では、上記容器内に上記制汗剤組成物が充填されている。本発明の制汗剤では、上記容器が、ロールオン容器であることが好ましい。本発明の制汗剤は、ロールオンタイプの制汗剤として好適に用いられる。
[Antiperspirant]

The antiperspirant of the present invention comprises a container and the above-described antiperspirant composition. In the antiperspirant, the container is filled with the antiperspirant composition. In the antiperspirant of the present invention, the container is preferably a roll-on container. The antiperspirant of the present invention is suitably used as a roll-on type antiperspirant.

　上記ロールオン容器は、塗布部にロールを備える。ロールは、円筒部材であってもよく、球状部材であってもよい。
The roll-on container includes a roll in the application unit. The roll may be a cylindrical member or a spherical member.

　ロールオンタイプの制汗剤は、制汗剤組成物を手に付けて肌等の塗布対象部位に塗布することなく、制汗剤組成物を塗布対象部位に直接かつ均一に塗布することができる。すなわち、ロールオンタイプの制汗剤は、塗布性に優れる。ロールオンタイプの制汗剤は、例えば、腋などの肌に、ロールオン容器内の制汗剤組成物を容易に直接塗布することができる。
The roll-on type antiperspirant can directly and uniformly apply the antiperspirant composition to the application target site without applying the antiperspirant composition to the application target site such as skin. That is, the roll-on type antiperspirant is excellent in applicability. With the roll-on type antiperspirant, for example, the antiperspirant composition in the roll-on container can be directly applied directly to skin such as wrinkles.

　なお、本発明の制汗剤組成物は、上述したロールオンタイプの制汗剤としてだけでなく、スティックタイプ、シートタイプ、ジェルタイプ、ローションタイプ、及びスプレータイプ等の制汗剤としても好適に用いることができる。この場合に、上記制汗剤組成物は、それぞれのタイプの制汗剤として用いるために適した容器内に充填される。
The antiperspirant composition of the present invention is suitably used not only as the roll-on type antiperspirant described above but also as an antiperspirant such as a stick type, a sheet type, a gel type, a lotion type, and a spray type. be able to. In this case, the antiperspirant composition is filled into a container suitable for use as each type of antiperspirant.

　以下に、本発明の構成と本発明の効果との関連性を更に詳細に説明する。
Hereinafter, the relationship between the configuration of the present invention and the effects of the present invention will be described in more detail.

　成分（Ｃ）、成分（Ｄ）、又は成分（Ｃ）と成分（Ｄ）との双方を含まない従来の制汗剤組成物では、制汗効果が十分ではなかったり、汗等により制汗剤組成物が流れ落ちたりするなどして、体臭防止効果が低下することがある。さらに、制汗剤組成物にヒドロキシプロピルセルロースのような親水性の増粘剤が単に配合された場合には、汗等により制汗剤組成物が流れ落ち易くなり、体臭防止効果の持続性を高めることは困難である。
In the conventional antiperspirant composition which does not contain component (C), component (D), or both component (C) and component (D), the antiperspirant effect is not sufficient, or the antiperspirant is caused by sweat or the like. The effect of preventing body odor may decrease due to the composition flowing down or the like. Furthermore, when a hydrophilic thickener such as hydroxypropylcellulose is simply blended in the antiperspirant composition, the antiperspirant composition is likely to flow off due to sweat or the like, and the sustainability of the body odor prevention effect is increased. It is difficult.

　これに対して、本発明の制汗剤組成物では、成分（Ｃ）と成分（Ｄ）とが併用されているので、制汗効果を高めることができる。また、本発明の制汗剤組成物では、成分（Ｃ）が配合されているので、肌への付着性を高めることができる。したがって、成分（Ｃ）と成分（Ｄ）との併用により、制汗効果に優れ、さらに持続性に優れた体臭防止効果を発揮することができる。成分（Ｃ）と成分（Ｄ）とが併用されているという構成は、重要かつ技術的意義のある構成である。
On the other hand, since the component (C) and the component (D) are used in combination in the antiperspirant composition of the present invention, the antiperspirant effect can be enhanced. Moreover, in the antiperspirant composition of this invention, since the component (C) is mix | blended, the adhesiveness to skin can be improved. Therefore, the combined use of the component (C) and the component (D) can exhibit a body odor preventing effect that is excellent in antiperspirant effect and excellent in sustainability. The configuration in which the component (C) and the component (D) are used in combination is an important and technically significant configuration.

　さらに、成分（Ｃ）と成分（Ｄ１）とが併用されている場合には、塗布された部分に良好な皮膜が形成し、かつ適度な疎水性が付与される。その結果、耐水性が高まり、汗等による制汗剤組成物の流れ落ちをより一層効果的に抑制することができ、肌への付着性をより一層高めることができる。さらに、成分（Ｃ）と成分（Ｄ１）とが併用されている場合には、塗布時に肌から垂れ落ちたり、塗布後にべたつき感や肌のつっぱり感を感じたりする等の塗布時及び塗布後の不快感をより一層効果的に抑えることができる。
Furthermore, when the component (C) and the component (D1) are used in combination, a good film is formed on the applied portion, and appropriate hydrophobicity is imparted. As a result, the water resistance is enhanced, the flow of the antiperspirant composition due to sweat or the like can be more effectively suppressed, and the adhesion to the skin can be further enhanced. Furthermore, when the component (C) and the component (D1) are used in combination, it drips from the skin at the time of application, or feels sticky or firm after application, etc. Discomfort can be more effectively suppressed.
