ECHEMI Editorial Reference

Drometrizole trisiloxane is a photostable UVA and UVB light filter. The compound is a lipophilic benzotriazole derivative marketed as Meroxyl XL by L'Oreal, although sunscreens with drometrizole trisiloxane are currently only approved for use in the EU, Canada, Australia, and Japan, among other countries. Despite being used elsewhere in the world with relatively few reports of adverse reactions, the FDA continues to cite that the existing scientific record is not sufficient to establish the compound as being generally recognized as safe and effective for over-the-counter sunscreen use.
