|Section2= |Section3= }} Drometrizole trisiloxane (INCI) is a lipophilic benzotriazole derivative marketed as Mexoryl XL by L'Oréal and is used in sunscreens to absorb UV radiation. It is a broad-spectrum UV absorber with two absorption peaks, one at 303 nm (UVB) and one at 344 nm (UVA). Just like Mexoryl SX (ecamsule), it is used exclusively in products by L'Oréal owned brands. Drometrizole trisiloxane and ecamsule are often used together, because they show a synergistic effect in protection. ==Availability== Sunscreens with drometrizole trisiloxane are approved within the EU,〔(COUNCIL DIRECTIVE of 27 July 1976 on the approximation of the laws of the Member States relating to cosmetic products )〕 Canada,〔(Sunburn Protectants ), Health Canada〕 Australia,〔(Australian Regulatory Guidelines for OTC Medicines - Chapter 10 )〕 Japan,〔 〕 and other countries, but not in the United States. 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「Drometrizole trisiloxane」の詳細全文を読む スポンサード リンク
