Description

本発明は、洗浄剤組成物、詳細には粉体乳化系洗浄剤組成物に関する。   The present invention relates to a detergent composition, and more particularly to a powder emulsified detergent composition.

皮膚や毛髪上には、通常の汚れ以外に皮脂やメイクアップ化粧料があるため、皮膚及び毛髪用の洗浄剤には、通常の汚れ以外に油性成分を除去するために種々の界面活性剤、油性成分、スクラブ剤等を配合した洗浄剤が用いられている。これら従来の洗浄剤に用いられるスクラブ剤としては、食塩、ポリエチレンビーズ、クルミ等の植物種子破砕物、結晶セルロース、ワックス粒子、ポリエチレン造粒粒子、エリスリトール等が用いられている(特許文献1〜5)。   Since there are sebum and makeup cosmetics on the skin and hair, in addition to normal stains, various detergents for removing oily components other than normal stains are included in the cleaning agents for skin and hair. A cleaning agent containing an oily component, a scrub agent and the like is used. Examples of scrubbing agents used in these conventional cleaning agents include crushed plant seeds such as salt, polyethylene beads, and walnuts, crystalline cellulose, wax particles, polyethylene granulated particles, and erythritol (Patent Documents 1 to 5). ).

一方、皮脂やメイクアップ化粧料を除去するための洗浄剤としては、これらの成分を可溶化するために多量の非イオン界面活性剤、油性成分等を配合した組成物が用いられている(特許文献6、7)。   On the other hand, as a cleaning agent for removing sebum and makeup cosmetics, a composition containing a large amount of a nonionic surfactant, an oily component, etc. is used to solubilize these components (patent) References 6 and 7).

特開平3−123732号公報Japanese Patent Laid-Open No. 3-123732 特開平10−338625号公報JP-A-10-338625 特開2004−189612号公報JP 2004-189612 A 特開2003−261436号公報JP 2003-261436 A 特開2011−121891号公報JP 2011-121891 A 特開平6−16523号公報JP-A-6-16523 特開2008−184415号公報JP 2008-184415 A

しかしながら、多量の界面活性剤を配合した洗浄剤はすすぎのために多量の水と手間が必要であり、またスクラブ剤配合洗浄剤においても皮脂やメイクアップ化粧料を除去するには多量の水を必要とし、すすぎの手間の問題は解決されておらず、さらに水の使用量の少ない地球環境にやさしい洗浄剤が望まれている。また、多量の油性成分を配合した洗浄剤は、洗浄後の皮膚上に油性成分が残存するため、後の洗浄が必要になり、手間が増えるという問題がある。   However, a detergent containing a large amount of surfactant requires a large amount of water and labor for rinsing, and a scrub agent-containing detergent also requires a large amount of water to remove sebum and makeup cosmetics. The problem of necessity and rinsing has not been solved, and there is a demand for a cleaner that is friendly to the global environment and uses less water. In addition, a cleaning agent containing a large amount of oily components has a problem that since the oily components remain on the skin after washing, subsequent washing is required and labor is increased.

従って、本発明の課題は、多量の界面活性剤を必要とせず、簡便な操作で皮脂やメイクアップ化粧料等の皮膚や毛髪上の汚れを洗浄除去できる新たな洗浄剤を提供することにある。   Accordingly, an object of the present invention is to provide a new cleaning agent that does not require a large amount of surfactant and can clean and remove dirt on the skin and hair such as sebum and makeup cosmetics by a simple operation. .

そこで本発明者は、皮脂等の油性成分の新たな除去手段について検討したところ、比表面積が大きく、かつ多孔質である無機粉体と揮発性液状油剤と水とを組み合わせれば、粉体乳化系組成物が得られ、当該組成物を用いれば、油性成分を吸着して皮膚や毛髪から効率良く除去できることを見出し、本発明を完成した。   Therefore, the present inventor examined a new means for removing oily components such as sebum. When the inorganic powder having a large specific surface area and porous, a volatile liquid oil, and water were combined, powder emulsification was performed. A system composition was obtained, and when the composition was used, the oily component was adsorbed and found to be efficiently removed from the skin and hair, and the present invention was completed.

すなわち、本発明は、次の成分(A)〜(C):
(A)比表面積が600〜2000m2/gの多孔質無機粉体、
(B)室温で揮発性の液状油剤
(C)水

Therefore, in any system, if the cleaning composition of the present invention is used, skin and hair stains can be removed by a completely new cleaning operation.

本発明の洗浄剤組成物は、静置した状態においては、水中油型乳化組成物であっても、多層(たとえば、油相と、水相の2層)に分離しており、相互に乳化はしていないものでも良い。多層に分離した多層液状洗浄剤を使用する際には、洗浄剤組成物を振とう混合することにより乳化する。具体的には、洗浄剤組成物が入った容器を手に握り、約10〜30cmの幅で、5〜20回程振り混ぜることで、分離した洗浄剤を乳化させることができる。得られた乳化物はO/W型エマルジョンとなる。この乳化物はメイキャップの施された肌等に塗布して、洗浄剤として使用される。使用者が本発明の洗浄剤組成物を皮膚又は毛髪に塗布している間は、乳化状態を維持する。さらに、所定時間経過すると、多層液状洗浄剤は再び、多層に分離する。なお、本発明はこの実施形態に限定されるものではない。   When the cleaning composition of the present invention is allowed to stand, even if it is an oil-in-water emulsion composition, it is separated into multiple layers (for example, two layers of an oil phase and an aqueous phase) and emulsified with each other. You may not have. When using a multilayer liquid detergent separated into multiple layers, the detergent composition is emulsified by shaking and mixing. Specifically, the separated cleaning agent can be emulsified by grasping the container containing the cleaning composition and shaking the mixture about 5 to 20 times in a width of about 10 to 30 cm. The obtained emulsion becomes an O / W type emulsion. This emulsified product is applied to a skin having a makeup and used as a cleaning agent. While the user applies the cleaning composition of the present invention to the skin or hair, the emulsified state is maintained. Further, when a predetermined time has elapsed, the multilayer liquid cleaning agent is separated into multiple layers again. Note that the present invention is not limited to this embodiment.

本発明の洗浄剤組成物の洗浄対象としては、汗・皮脂などの油成分やメイクアップ化粧料が存在するもの、例えば皮膚、毛髪が好ましい。より具体的には、顔、手、足、全身、毛髪等が挙げられる。従って本発明の洗浄剤組成物は、皮膚又は毛髪用洗浄剤として有用である。   As the cleaning object of the cleaning composition of the present invention, those containing oil components such as sweat and sebum and makeup cosmetics such as skin and hair are preferable. More specifically, face, hand, foot, whole body, hair and the like can be mentioned. Therefore, the cleaning composition of the present invention is useful as a cleaning agent for skin or hair.

本発明の洗浄剤組成物を用いて皮膚又は毛髪を洗浄するには、例えば必要により振とうして、皮膚又は毛髪に本発明の洗浄剤組成物を塗布し、洗浄操作(例えば擦る、マッサージする等)を行い、次いで残存した粉体状物を除去すればよい。洗い流す操作を行ってもよいが、特に洗い流す操作を行わなくても良い。これは、例えば皮膚上の汚れが乳化した多孔質無機粉体に吸着し、揮発性液状油剤は揮発し、その後乾燥により皮膚上には汚れを吸着した多孔質無機粉体が残存することによる。   In order to clean the skin or hair using the cleaning composition of the present invention, the cleaning composition of the present invention is applied to the skin or hair by shaking, for example, if necessary, and a cleaning operation (for example, rubbing or massaging). Etc.) and then the remaining powdered material is removed. Although the washing operation may be performed, the washing operation may not be performed. This is because, for example, dirt on the skin is adsorbed on the emulsified porous inorganic powder, the volatile liquid oil is volatilized, and then the porous inorganic powder on which the dirt is adsorbed remains on the skin by drying.

次に、本発明の洗浄剤組成物の製造方法を示す。具体的には、油相成分(成分(A)、(B))を均一に混合し、その後、攪拌しながら水相((C)成分)を添加し、洗浄剤組成物を得る。
また、成分(D)を含む場合は、油相成分(成分(A)、(B)、(D))を均一に混合し、その後、攪拌しながら水相((C)成分)を添加し、洗浄剤組成物を得る。なお、本発明はこの製造方法に限定されるものではない。
Next, the manufacturing method of the cleaning composition of this invention is shown. Specifically, the oil phase components (components (A) and (B)) are uniformly mixed, and then the water phase (component (C)) is added with stirring to obtain a cleaning composition.
When the component (D) is included, the oil phase components (components (A), (B), (D)) are mixed uniformly, and then the water phase (component (C)) is added with stirring. A cleaning composition is obtained. The present invention is not limited to this manufacturing method.
