Perfumer's Notebook: Stability of Fragrance Profile

An essential feature of any well compounded fragrance is its property of maintaining a constant profile during its exposure. This applies to fragrances applied to the skin, as with colognes or perfumes, or exhibited on the surface of toilet soaps.

The rate at which a substance evaporates is, of course, a direct function of its vapor pressure, i.e. its tendency to change from liquid or solid to a gas.
