Predictive Science Produces Better Products at Better Profit Margins

Computational approaches, such as predictive modeling, provide a rational approach for the discovery of new compounds based on molecular attributes. But did you know that data integration and predictive analytics offer ways to improve and dramatically speed up the R&D discovery process on the basis of experimental data that you have in-house right now?

A Primer on Perfuming Polymers

This primer will attempt to cover, as painlessly as possible, some basic polymer physics and volubility theory and then show how this knowledge can be applied in general and for a specific example

Perfume Materials: Prediction of Fragrance Headspace Concentrations from Physico-Chemical Properties

Disposition of fragrance ingredients on skin

Improving Fragrance Performance Using Intensity Plots (iPlots)

One of the challenges faced by functional perfumery is balancing olfactive intensity and character of a fragrance through each product utilization stage.

Perfumer POV: An Opportunity to Reinvent the Fragrance Creation Process

Perfumers will have to collaborate and work hand in hand with R&D to innovate and find new notes to replace the restricted and/or banned ones; otherwise they may be forced to try to compose new melodies on a piano missing half the keys.

Focus on Perception: Non-Attentive Smelling and Perfumery Practices

The key function of scent in subconsciously shaping all aspects of consumer perception

Adesmia Boronioides, also called Paramela belongs to the family of Fabacea. It is a small bush that grows up between 0.4 and 2 meters high.

Inside Paramela Essential Oil: Perfumery Usage, Chromatographic Profile and Chemical Composition

The olfactory profile of this oil is unusual and very interesting with great tenacity and fixation.

F&F Literature Review: Pinpointing Performance

In this literature review, P&F examines the recent studies and research on the performance of F&F materials.

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.

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.

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.

Pink Pepper Fruit and Leaf Oils

This month's column discusses the chemical composition of pink pepper fruit and leaf oils.

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.

Chemical Characterization of Vanilla pompona Scheide, Part I

In this four-part series, researchers extensively study the composition of Vanilla pompona for fragrance applications. Here, existing literature on V. pompona is reviewed and compared with V. tahitensis and V. planifolia. Test protocols for GC-MS and DTD-GC-MS are described, and some results are discussed.

Separation of Fragrance Materials from Perfumed Consumer Products

In isolating the fragrance materials, which are usually present only at low levels, the analytical chemist is confronted with a formidable separation challenge, particularly when the sample also contains emulsifiers, surfactants, clarifiers, thickeners, solubilizers, pigments, antioxidant, UV-absorbers, preservatives, solvents, and other materials.

Chemical Characterization of Vanilla pompona Scheide, Part IV

Vanilla pompona is resistant to climate change and diseases, and therefore is preferred for hybridization with V. planifolia. Its chemical characterization was carried out in a series of studies, described in this last of four parts.
