It is an ester derivative of PABA. This aromatic chemical absorbs ultraviolet rays thereby preventing sunburn. However, it's chemical structure and behaviour is similar to an industrial free radical generator.〔 In Europe this chemical was withdrawn in 1989 for unstated reasons. In the US it was never approved for use in sunscreens. ==Photobiology== The photobiological properties of padimate O and padimate A resemble that of Michler's ketone. These compounds have been shown to increase the lethal effects of UV-radiation on cells.〔 This photochemistry is relevant to the sunscreen controversy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Padimate A」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
