Gas Chromatographic Analysis on Turkish Rose Oil, Absolute and Concrete

The analysis of rose products maybe realized by gas or liquid chromatographic techniques. Our investigations showed that liquid chromatography have been used only in a few studies to separate essential oils and terpenoid compounds, and a sufficient separation has not been obtained.

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.

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.

The Sweet Smell of Standards

We can conclude with confidence that the demand for new international standards in the field of essential oils will continue to grow. We need such standards to facilitate world trade and to promote the quality of the products.

Stop Making Scents?

The fragrance industry is commonly known for the production of costly perfumes, but its greatest assets are the intellectual properties behind these tangible creations. The most valuable of these are fragrance formulas, any one of which may cost several hundred thousands of dollars and require more than a year to develop.

Aroma-Chology: A Status Review

The term Aroma-Chology (a Service Mark of the Olfactory Research Fund) was coined in 1982 to denote the science that is "dedicated to the study of the interrelationship between psychology and ... fragrance technology to elicit a variety of specific feelings and emotions—relaxation, exhilaration, sensuality, happiness and wellbeing—through odors via stimulation of olfactory pathways in the brain, especially the limbic system."

Editor's Note: Strength in Diversity

Consumers continue to request more natural, cleaner, organic, non-GMO and transparently labeled ingredients in their products, which provides the F&F industry an opportunity to look deeper into the "culture" of clean ingredients.

21st Century Leap of Fragrance

Do we have more to offer our sense of smell than the next niche fragrance?

The Future of Fluorocarbons, Status Report

Our research effort continues with other fluorocarbon compounds, which may offer better end use performance and economic characteristics than those provided by FC-22 and FC142b. The goal is to find propellants that present the greatest consumer advantages should circumstances dictate the replacement of the propellants presently used.

A chemometric study of human odor perception

Thus this work suggests that, from this data set, the human odor sensory spectrum can be. explained by the existence of a two-dimensional continuum with the coordinates (odor) of a molecule determined by its directed dipole and electron donor-acceptor ability. This result is pleasantly straightforward and makes a trained expert’s ability to distinguish thousands of different odors reasonable.

Fragrances and Fragranced Products: A Strong Alliance

The powerful appeal of many soaps, detergents and cleaning products to consumers is often directly related to the products’ scents. Producers and suppliers of cleaning products understand that an amazing amount of research and innovation goes into the creation of product fragrances and that fragrance ingredients are at the leading edge in the defense of protections for trade secrets.

Strategies To Analyze Suspected Allergens In Fragrances

The 7th amendment of the European Cosmetics Directive (2003/15/EC) was published earlier this year.1 Among other things it will, when enacted into national legislation, require manufacturers of cosmetics to indicate in their ingredient statements, the names of 24 chemically defined substances (T-1) and two natural extracts when they are present at concentrations exceeding 0.001 percent in cosmetics that are intended to remain on the skin, or 0.01 percent in those that are rinsed off the skin.

Some Aspects Of Qualitative Structure-Odor Relationships

Qualitative odor-structure relationships have been applied for more than a century. The results of these studies are mostly the consequence (outcome) of the application of common sense gathered by experience. Two main features characterize the molecular structures of odorant molecules: “electronicity” (electronic charge distribution over a molecule) and “stereocity” (volume, shape and profile of a molecule).

Strategies to Analyze Suspected Allergens in Fragrances

This paper aims to describe the analytical strategy that has been developed at Firmenich to monitor suspected allergens in fragrance concentrates.

Trends and developments: Organic Standards for Personal Care Products

Developing common-sense standards to boost the personal care industry and aid the consumer. Few subjects in the personal care world have generated as much interest and attention in recent years as the development of new standards in organic personal care. For those involved in the product-development side of the natural/organic business, it has been a reflective -- and sometimes pensive -- period.
