About this ingredient: EU CosIng ingredient registry (via Open Beauty Facts taxonomy) ↗

UV filter: Filters some UV radiation. The ingredient label does not establish a finished product's SPF or UVA protection.
Uv absorber: Protects the formulation against UV light. This role is distinct from a skin-protecting UV filter.

Function definitions: European Commission ingredient function definitions (SCCNFP/0299/00, pages 16 to 20) ↗

Registry functions describe possible formulation roles, not results for a finished product. A dictionary entry is not an approval or a safety assessment.
