Overview

**BAY987521** is a Bayer development designation used for a topical Coppertone sunscreen test product. It was evaluated in healthy-volunteer studies for sun-protection performance, including sun protection factor, UVA protection factor, persistent pigment-darkening dose, ocular irritation, phototoxicity, and photoallergy. Public trial records identify BAY987521 as a sunscreen lotion, but do not disclose a complete active-ingredient composition or establish a single molecular entity; records also reference formulations Y49-103 and Y71-150. Its intended effect is broad photoprotection through topical ultraviolet-filter activity rather than modulation of a defined biological target.
