Perfume / Fragrance
A cosmetic scent that usually has a high-alcohol solvent and can contain animal-derived musk.
Why this is a critical point
Perfume and eau de toilette typically use ethanol as their main solvent (sometimes above 70%), and occasionally natural musk from a musk deer's gland. For cosmetics applied to the skin (rather than ingested), the fiqh view is relatively more lenient than for consumed products, but choosing a certified product is still advised for certainty, especially before worship.
Halal alternative
Alcohol-free fragrance or halal-certified synthetic musk.
