従来、化粧料に紫外線防止効果を付与するために種々の有機系紫外線吸収剤が用いられている。特に、無機粉体に有機化合物である紫外線吸収剤を複合化した紫外線遮蔽粉体が知られている。 Conventionally, various organic ultraviolet absorbers have been used to impart a UV protection effect to cosmetics. In particular, an ultraviolet shielding powder obtained by combining an inorganic powder with an ultraviolet absorber that is an organic compound is known.
例えば、国際公開第2010/098249号パンフレットには、基材となる粉体表面に、紫外線吸収能を有する有機化合物をコーティングしてなる複合粉体が開示されている。この複合粉体は、紫外線吸収能を有する有機化合物と紫外線散乱能を有する無機系顔料とを複合させたものであり、化粧料への配合が安定的に可能な粉末であって、高い紫外線吸収効果を維持し、分散性の良好な有機系紫外線吸収剤であると記載されている。このような複合粉体として、微粒子酸化チタンの表面にブチルメトキシジベンゾイルメタンをコーティングした複合粉体が開示されている。 For example, International Publication No. 2010/098249 pamphlet discloses a composite powder obtained by coating the surface of a powder serving as a base material with an organic compound having an ultraviolet absorbing ability. This composite powder is a composite of an organic compound having an ultraviolet absorbing ability and an inorganic pigment having an ultraviolet scattering ability, and is a powder that can be stably incorporated into cosmetics and has a high ultraviolet absorbing ability. It is described that it is an organic ultraviolet absorber that maintains its effect and has good dispersibility. As such a composite powder, a composite powder in which butylmethoxydibenzoylmethane is coated on the surface of fine particle titanium oxide is disclosed.
また、特表2003−528027号公報には、紫外線防止効果を付与するための光線遮蔽調製物として、標準状態で固体の形態にある有機UVフィルタ−成分、特定構造を有するアルキルグルコシド等から選択された非イオン性界面活性剤、シリコーン乳化剤などを含有する化粧料又は皮膚化学的W/Oエマルションが開示されている。 In addition, in Japanese translations of PCT publication No. 2003-528027, a light shielding preparation for imparting an ultraviolet ray preventing effect is selected from organic UV filter components in a solid form in a standard state, alkyl glucosides having a specific structure, and the like. Cosmetic or dermatological W / O emulsions containing nonionic surfactants, silicone emulsifiers and the like are disclosed.
しかしながら、ブチルメトキシジベンゾイルメタンを表面に有する粉体を乳化物に配合すると、経時により乳化物中で凝集を生じることがある。また、ブチルメトキシジベンゾイルメタンを表面に有する複合粉体を配合した乳化物を含む化粧料の使用においては、塗布時のみずみずしさ、塗布後のべたつき等の使用感が損なわれることがある。
更に、乳化物を含む化粧料において、塗布後のべたつき等の使用感の低下を抑制するには、油中水型の乳化物よりも水中油型の乳化物を適用することが望ましい。このため、紫外線遮蔽効果を有しながらも、経時安定性及び使用感についても兼ね備えた化粧料に対する要求が高まっている。
However, when formulating a powder having a butyl methoxy di benzoyl methane to the surface emulsion, which may cause aggregation emulsion in over time. Also, in the cosmetic use, including emulsion blended composite powder having a butyl methoxy di benzoyl methane on the surface, freshness during application, there may feeling of stickiness and the like after the coating is impaired.
Furthermore, in cosmetics containing an emulsion, it is desirable to apply an oil-in-water emulsion rather than a water-in-oil emulsion in order to suppress a decrease in feeling of use such as stickiness after application. For this reason, the request | requirement with respect to cosmetics which has the temporal stability and the usability | use_condition while having an ultraviolet-ray shielding effect is increasing.
本発明は、高い紫外線遮蔽効果と、優れた経時安定性と、優れた使用感とを備えた水中油型化粧料を提供することを課題とする。 An object of the present invention is to provide an oil-in-water cosmetic having a high ultraviolet shielding effect, excellent temporal stability, and excellent usability.

From the viewpoint of usability, the surface-treated powder is preferably contained in the aqueous phase.
That the surface-treated powder is contained in the oil phase means that the surface-treated powder is dispersed in the oil droplets of the oil-in-water cosmetic. That the surface-treated powder is contained in the water phase means that the surface-treated powder is dispersed in the water phase of the oil-in-water cosmetic.
水中油型化粧料が表面処理粉体を水相に含む場合、例えば、水相組成物に表面処理粉体を他の成分と共に直接配合してもよいし、水、1,3−ブチレングリコール等の水性媒体を分散媒として用いて、表面処理粉体を含む水性スラリーを調製し、スラリーの形態で他の成分と配合してもよい。 When the oil-in-water cosmetic contains the surface-treated powder in the aqueous phase, for example, the surface-treated powder may be directly blended with other components in the aqueous phase composition, water, 1,3-butylene glycol, etc. An aqueous slurry containing the surface-treated powder may be prepared using the aqueous medium as a dispersion medium, and blended with other components in the form of a slurry.

It was.
また、更に、アクリロイルジメチルタウリン塩を共重合成分として含む共重合体を組み合わせることにより、水中油型化粧料の経時安定性がより向上することがわかった(実施例3〜実施例6)。 Furthermore, it was found that the stability over time of the oil-in-water cosmetic was further improved by combining a copolymer containing acryloyldimethyltaurine salt as a copolymerization component (Examples 3 to 6).
