Abstract
Description
本発明は、化粧料に関するものである。より詳細には、静置時には二層に分離しているが、振とうすることによって容易に乳化する化粧料に関するものである。 The present invention relates to cosmetics. More specifically, the present invention relates to a cosmetic that separates into two layers when left standing but is easily emulsified by shaking.
従来、化粧料として静置時には二層に分離しているが、使用時に振とうすることによって乳化させてから適用する二層型化粧料が知られている。このような化粧料は、一般的に水性成分から構成される水相と、油性成分から構成される油相とを含んでいる。このような二層型化粧料を振とう後に肌などに適用すると、水性成分および油性成分のそれぞれによって得られる使用感や効能を同時に得ることができるという特徴がある。例えば、水性成分からは、水溶性薬剤による効能やさっぱりとした使用感を得ることができ、油性成分からは油溶性薬剤による効能や洗浄効果を得ることができる。より具体的には、洗浄料を二層型洗浄料とすることで、油性成分によって水不溶性物質の除去性能を高めながら、水性成分によってさっぱりとした使用感を得ることができる。このため、ウォータープルーフのメーキャップなども容易に除去できる高い洗浄力を有しながら、使用後のべたつきの少ない、洗浄料とすることができる。 Conventionally, a two-layer type cosmetic is known, which separates into two layers when left standing as a cosmetic, but is applied after being emulsified by shaking at the time of use. Such cosmetics generally contain an aqueous phase composed of aqueous components and an oil phase composed of oily components. When such a two-layer cosmetic composition is shaken and then applied to the skin or the like, it is characterized in that it is possible to simultaneously obtain the feeling of use and efficacy obtained by each of the aqueous component and the oil component. For example, from the aqueous component, it is possible to obtain the effect of the water-soluble agent and a refreshing feel, and from the oil-based component, it is possible to obtain the effect and cleansing effect of the oil-soluble agent. More specifically, by using a two-layer type cleanser as the cleanser, it is possible to obtain a refreshing feel while using the aqueous component while enhancing the removal performance of water-insoluble substances by the oily component. Therefore, it is possible to obtain a cleansing agent that has high detergency to easily remove waterproof make-up and is less sticky after use.
しかしながら、二層型化粧料においては、静置時にきれいに二層に分離する分離性が必要である。なぜならば、分離が不十分であると製品としての印象が悪く、視覚的先入観によって十分な性能または効能が得られるのか不安を与えることがあるためである。しかし、本発明者らの検討によれば、二層型化粧料の防腐性を高めるために、多価アルコール、安息香酸ナトリウム、またはイソプロピルアルコールなどの防腐性能を有する添加剤を組み合わせると、きれいに分離しないことがあることがわかった。このため、そのような成分が組み合わされた場合にも、優れた分離性を示す二層型化粧料が望まれている。 However, two-layer type cosmetics require separability to cleanly separate into two layers when allowed to stand. This is because if the separation is insufficient, the impression of the product is poor, and visual prejudice may cause anxiety as to whether sufficient performance or efficacy can be obtained. However, according to the study of the present inventors, in order to enhance the antiseptic properties of the two-layer cosmetic, if an additive with antiseptic properties such as polyhydric alcohol, sodium benzoate, or isopropyl alcohol is combined, it can be separated cleanly. I found out that there are some things I don't. Therefore, there is a demand for a two-layer cosmetic that exhibits excellent separability even when such components are combined.
このような観点から、本発明者らが検討したところ、防腐剤を含む二層型化粧料の分離性を高めるのに、特定の材料が有効なことがわかった。すなわち。本発明はかかる知見に基づくものであり、その解決しようとする課題は、優れた使用感や洗浄能力を有し、視覚的に満足を与える分離性、振とうの際に速やかに乳化する乳化容易性を兼ね備えた化粧料を提供することである。 From this point of view, the present inventors have studied and found that a specific material is effective in enhancing the separability of a two-layer cosmetic containing a preservative. Namely. The present invention is based on such findings, and the problems to be solved are that it has an excellent feeling of use and cleansing ability, has a visually satisfying separation property, and is easy to emulsify by quickly emulsifying when shaken. To provide a cosmetic having both properties.

Oils that are solid at room temperature can also be used as long as they become liquid when mixed with other oils.
本発明による化粧料は、本発明の効果を阻害しない範囲で、上記した以外の、化粧料に通常用いられる成分を配合することができる。これらの成分としては、例えば、増粘剤、保湿剤、水溶性薬剤（例えば、アルブチン、アスコルビン酸グルコシド、トラネキサム酸、４－メトキシサリチル酸塩等）、紫外線吸収剤、キレート剤、ｐＨ調製剤、防腐剤、色素、染料、界面活性剤、粉末成分等が挙げられる。 The cosmetics according to the present invention can contain ingredients commonly used in cosmetics other than those mentioned above, as long as the effects of the present invention are not impaired. These ingredients include, for example, thickeners, moisturizers, water-soluble agents (eg, arbutin, ascorbic acid glucoside, tranexamic acid, 4-methoxysalicylate, etc.), ultraviolet absorbers, chelating agents, pH adjusters, preservatives. agents, pigments, dyes, surfactants, powder components, and the like.
本発明による化粧料は、静置時には水層と油層とが明確に分離して、それぞれが濁りの無い透明な層を形成する、優れた外観を有する。二層に分離した化粧料は、容器内に収容したまま、手などで振とうすることで容易に均一に乳化して、使用に付すことができる。そして、乳化させた後、短時間、例えば６時間以下、静置することで、再び水層と油層とが明確に分離する。 The cosmetic according to the present invention has an excellent appearance in which the water layer and the oil layer are clearly separated from each other when allowed to stand, and each forms a transparent layer without turbidity. The cosmetic material separated into two layers can be easily and uniformly emulsified by shaking with a hand or the like while being accommodated in a container, and then used. Then, after emulsification, the water layer and the oil layer are clearly separated again by allowing to stand for a short period of time, for example, 6 hours or less.
この二層型化粧料は、単純に二層に分離しているのでは無く、使用時には水相と油相とのそれぞれの長所を併せ持った性能を示すものである。具体的には、水相または油相に適切な薬剤等を配合することによって、化粧水などとすることができるほか、洗浄料とすることもできる。本発明による二層型化粧料は、洗浄料としては、油相による洗浄効果を発揮させると同時に、水相によるさっぱりとした使用感を与えることができる。 This two-layer type cosmetic is not simply separated into two layers, but exhibits performance that combines the respective advantages of the aqueous phase and the oil phase during use. Specifically, by blending an appropriate chemical or the like in the water phase or the oil phase, it can be used as a lotion or the like, and can also be used as a cleansing agent. As a cleansing agent, the two-layered cosmetic composition according to the present invention can exhibit a cleansing effect due to the oil phase and at the same time can provide a refreshing feel due to the water phase.
［化粧料の製造方法］
本発明による化粧料は、各成分を配合して混合することで製造することができる。混合順序は特に限定されないが、水相と油相とをそれぞれ調製し、その後、それらを単一の容器に封入することが一般的である。すなわち、水相と油相とをそれぞれ調製し、その後、水相と油相とを配合することで化粧料を調製することができる。
[Method for producing cosmetics]
The cosmetic according to the present invention can be produced by blending and mixing each component. The order of mixing is not particularly limited, but it is common to prepare an aqueous phase and an oil phase separately and then seal them in a single container. That is, the cosmetic can be prepared by preparing an aqueous phase and an oil phase, and then blending the aqueous phase and the oil phase.
以下の例に基づいて本発明を具体的に説明するが、本発明はこれらの例に限定されるものではない。含有率は特記しない限り、質量％で示す。 The present invention will be specifically described based on the following examples, but the present invention is not limited to these examples. Unless otherwise specified, the contents are shown in % by mass.
