Odour Classification of Perfumes

Odours of perfumes are mostly categorised as 'citrus', 'woody', 'floral' or 'oriental' but experts continue to describe the same fragrance with different words.

A new poll has found that Dame Elizabeth Taylor's scent is the 'Best-Selling Celebrity Perfumes Of All Time'.

They used the PR to classify the primary odour families of 14 commercial perfumes and found that the results closely matched those of experienced perfume makers.
