The Biochemistry and Psychology of Perfumery

The experimental work described int his paper represents some of the first attempts to study perfumery phenomena in an academic environment. Many complex questions to be asked about our reactions to fragrances are best tackled in a research group which is removed from the daily pressures of a manufacturing environment. There is increasing interest in chemoreception research.

International Perfume Standards Program

In summary, we determined that it was necessary to have a fresh fragrance oil quality control standard representative of the quality of oil available in any given overseas location. We recognize that ensuring worldwide quality required a central location to evaluate and approve the initial samples of oils before being purchased around the world. Once an initial quality was determined, it was necessary to assure that each location had access to a fresh quality control standard representing this quality. A procedure was then set up to assure annual replacement of quality control standards.

Perfumes--Effect of the Product Medium

Perfumer's Notebook. We have considered the phenomena of dilution, chemical reactions, and differences in solubility in the product as contributors to change of odor profile as a perfume is added to a product. Each of these factors has been examined as it affects the release of separate components from the surface of a product, Any may occur. Their existence emphasizes the need for perfumers to be informed of the chemical nature of the product they perfume. It also points to the need for testing of single odorants and simple blends at an early stage in formulation.

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. Marked change in profile during exposure may occur through lack of attention to relative evaporation rates of the perfume components. 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.
