What it is and what it does

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

Perfuming: A formulation role for perfume and aromatic raw materials that give a product its scent.

Function definitions: Danish Environmental Protection Agency: Cosmetic fragrance functions ↗

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