The present invention is a sunscreen cosmetic comprising 2,4-bis[[4-(2-ethylhexyloxy)-2-hydroxy]phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine and a specific benzotriazole derivative.
Also, the present invention is a sunscreen cosmetic comprising a specific benzotriazole derivative and a specific alkylaryl 1,3-propanedione silicone derivative.
An object of the present invention is to provide a sunscreen cosmetic that exhibits superior UV-A absorption capacity and excellent stability and also sufficiently dissolves 2,4-bis[[4-(2-ethylhexyloxy)-2-hydroxy]phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, which has low solubility and crystallizes easily.
Another object is to provide a sunscreen cosmetic that can synergistically improve the ultraviolet absorption capacity of conventional ultraviolet absorbents.
本发明是一种防晒化妆品,包括2,4-双[[4-(2-乙基己氧基)-2-羟基]苯基]-6-(4-甲氧基苯基)-1,3,5-三嗪和特定的苯并三唑衍生物。此外,本发明还是一种防晒化妆品,包括特定的苯并三唑衍生物和特定的烷基芳基1,3-丙二酮硅氧烷衍生物。本发明的目的是提供一种具有优异的UV-A吸收能力和优异稳定性的防晒化妆品,同时也能充分溶解2,4-双[[4-(2-乙基己氧基)-2-羟基]苯基]-6-(4-甲氧基苯基)-1,3,5-三嗪,该化合物溶解度低且易结晶。另一个目的是提供一种能够协同改善传统紫外线吸收剂的紫外线吸收能力的防晒化妆品。
