Why is purfume smelly?

Answer 1

Perfumes are volatile, they give off invisible gasses which are made of tiny complex molecules, all different shapes. These little shapes float in the air. When these shapes go up your nose they fit into certain receptors in your nose which match the shapes, and Hey Presto! You recognise the smell!

Different people prefer certain smells to others. Smells often evoke memories and the feelings associated with those memories. If the smells evoke nice memories, the perfume is appealing. But sometimes, for various reasons, some perfumes do not smell very nice. But this is all in the mind nose!

Answer 2

Perfume is scented because it contains a mixture of fragrant oils, solvents, and fixatives that emit an aroma when applied to the skin. The specific combination of these ingredients creates the unique smell of each perfume.
