Document Type and Number:
Japanese Patent JP2003532665
Kind Code:
A
Abstract:
By using 2,4-bis[[4-(2-ethylhexyloxy)-2-hydroxy]phenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, the photostability of dibenzoylmethane derivatives is substantially improved and, indirectly, stabilisation of cinnamic acid esters is also effected, by which means there are made possible photostable cosmetic compositions for protection against UV radiation which have a high sun protection factor and a high absorbance in both the UVA and UVB range.
