A kind of sun-proof constituent structure,It includes a containers with accommodating space； And one set sun-proof molecular cell in the what accommodating space,The sun-proof molecular cell system includes that different substituents benzaldehyde compound combines the sun-proof molecule of double -4 hydroxy coumarin and additive to mix,The molecular configuration of tonka bean camphor structure skeleton with conjugated double bond,The different substituents benzaldehyde compound combine double -4 hydroxy coumarin sun-proof molecule be (2,4- methoxy substitution phenylmethylene)-bis- -4- hydroxyl-cumarins,(3,5- methoxyl groups,4- hydroxyphenyl-methylene)-bis- -4- hydroxyl-cumarins,Or the molecule of the structural frameworks cumarin such as Fourth Ring and 4 hydroxy coumarin is combined,Between its content system Jie's what 99.999% ~ 80%. Contain the ultraviolet absorption ability of the had good result of molecular configuration of the tonka bean camphor structure skeleton of conjugated double bond through the sun-proof molecular cell, it can develop as good ultraviolet absorbing agent, in the sun-proof maintenance of configuration what, cosmetics, UV energy can be effectively absorbed and then reach sun-proof result, to reach the generation of prevention skin photoage and wrinkle.一種防曬組成物結構，其包含一具有容置空間之容器；以及一設於該容置空間中之防曬分子單元，該防曬分子單元係包含有不同取代基苯甲醛化合物結合雙-4-羥基香豆素之防曬分子及添加劑混合而成，具有共軛雙鍵之香豆素結構骨架之分子構造，該不同取代基苯甲醛化合物結合雙-4-羥基香豆素之防曬分子為(2,4-甲氧基取代苯基亞甲基)-雙-4-羥基-香豆素、(3,5-甲氧基，4-羥苯基亞甲基)-雙-4-羥基-香豆素，或結合四環與4-羥基香豆素等結構骨架香豆素之分子，其含量係介於99.999%~80%之間。透過該防曬分子單元含有共軛雙鍵之香豆素結構骨架之分子構造所具有良好效果之紫外線吸收能力，可發展為良好之紫外線吸收劑，配置於防曬保養、化妝品中，能有效地吸收紫外光能量進而到達防曬效果，以達到預防皮膚光老化及皺紋之產生。
