What is fragrance?

Answer 1

In consumer products such as perfume, soap and air fresheners, a fragrance is generally an oil created by a person called a perfumer. The oil itself, is made up of numerous ingredients that are combined to create a composite. These ingredients can be natural, such as Lilac oil, or synthetic, such as benzyl aldehyde (artificial cherry). When you smell the fragrance, what is happening is that a small amount of the oil is evaporating and being inhaled. The tiny particles of fragrance then latch onto the receptors in your nose. Your receptors figure out certain characteristics about them, such as shape, size, pH balance and chemical composition and send that information to your brain. Your brain then processes that information to give you a sensation that you interpret as smell.

Answer 2

Fragrance is a smell, an aroma, or an odor. It is usually associated with pleasant smells (such as flowers). It is also a synonym for perfume in some cases.
