A fragrance is not a single material of clearly defined properties, but rather a mixture of
individual chemicals, each behaving according to its own unique attributes. Characterizing
these chemicals separately, and then combining their effects, allows the behavior
of the complete fragrance composition in diverse media to be understood. Important
properties of fragrance chemicals include volatility, polarity, surface activity and stability.
Each fragrance component interacts with the chemical and structural nature of the
environment to determine the aesthetic and the physical characters of the final system.
The combined talents of the perfumer and the technical staff, working closely together,
are needed to create a successful commercial product.
