What is the difference between perfume/scent/fragrance?

A perfume produces a fragrance, but not all fragrances come from perfume. A perfume as a product is a fragrant composition formed of aroma-chemicals and or natural oils usually suspended in alcohol and water intended to be applied to the skin. A perfume (often listed as parfum) as an ingredient refers to the suspension itself, and can be found in innumerable products from laundry detergents to candles. Perfume as art refers to a perfume composed with a view to evoking a specific concept, place, period, event, or feeling. https://osmeperfumery.com/
