従来より、紫外線防御を目的として、種々の紫外線防御剤を配合した化粧料が市販されているが、日常での使用を想定して、みずみずしい使用感と高い紫外線防御能を兼ね備えた化粧料の市場が拡大してきている。特に近年、紫外線防御能を有する化粧料は、プールや海水浴で使用されたり、汗をかくシーンで使用されることも多く、紫外線防御効果持続の観点から、耐水性に優れたものが求められている。そこで、着手時のみずみずしさが期待される水中油型化粧料に、高分子化合物を配合することで、耐水性を得る技術（特許文献１、２）等が報告されている。 Conventionally, cosmetics containing various UV protection agents have been marketed for the purpose of UV protection, but assuming a daily use, the market for cosmetics that has a fresh feel and high UV protection ability Is expanding. Especially in recent years, cosmetics having UV protection ability are often used in swimming pools and sea bathing, and are often used in sweating scenes. From the viewpoint of sustaining UV protection effect, cosmetics with excellent water resistance are required. Yes. Then, the technique (patent documents 1, 2) etc. which obtain water resistance by mix | blending a high molecular compound with the oil-in-water type cosmetics from which freshness is anticipated at the time of starting are reported.
特許文献１は、カチオン性ポリマーとカルボキシメチルセルロースとから形成されるポリイオンコンプレックスを含有する水中油型化粧料が耐水性などの効果を有するといった報告である。また、特許文献２は、（アクリロイルジメチルタウリンアンモニウム／ＶＰ）コポリマー、（アクリル酸Ｎａ／アクリロイルジメチルタウリンＮａ）コポリマー、ポリメタクリル酸メチルの三種類の高分子の配合を含有する水中油型化粧料が耐水性などの効果を有するといった報告である。しかしながら、両報告とも、それら高分子特有のべたつきは依然として存在するうえに、耐水性も充分でなかった。
すなわち、着手時のみずみずしさを有したまま、べたつきが無く、さらに、耐水性に優れた紫外線防御効果を有する水中油型化粧料は知られていない状況である。
Patent Document 1 reports that an oil-in-water cosmetic containing a polyion complex formed from a cationic polymer and carboxymethylcellulose has effects such as water resistance. Patent Document 2 discloses an oil-in-water cosmetic containing a blend of three types of polymers: (acryloyldimethyltauronium ammonium / VP) copolymer, (Na acrylate / acryloyldimethyltaurine Na) copolymer, and polymethyl methacrylate. It is reported that it has effects such as water resistance. However, in both reports, the stickiness peculiar to these polymers still exists and the water resistance is not sufficient.
That is, there is no known oil-in-water cosmetic that has a freshness at the time of initiation, is not sticky, and has an ultraviolet protection effect that is excellent in water resistance.

Furthermore, it has been discovered that the addition of polyhydroxystearic acid improves the dispersion stability of dimethylsilylated silica and / or trimethylsilylated silica, and significantly improves water resistance. Furthermore, in addition to dimethylsilylated silica and / or trimethylsilylated silica, polyhydroxystearic acid, an oil-in-water cosmetic containing dimethicodiethylbenzalmalonate has not only an ultraviolet protection effect but also a start. The present invention was completed by finding out that it was excellent in freshness, water resistance of the coating film was better, and dispersion stability was also better.
