Skin Odor Value Technology for Fragrance Performance Optimization
By: Ahmet Baydar et al.
Since early times we have used perfume as the most intimate apparel to enhance our appeal. It clothes our skin with an invisible aura of fragrance providing it with a signature of personality and mood. Ideal fragrances are those which are a perfectly tailored match to our skin. This paper describes the methodological aspects of Givaudan-Roure's proprietary skin odor value technology and shows how it is used by perfumers in designing "haut couture" fragrances.

Material review: Kashmir Lavender Oil
By: Robert Adams and Tonya Yanke
A comparison of new Kashmir lavender oils with commercial lavender oils. The composition of two new Kashmir lavender oils were compared with nine commercial lavender oils using GC/MS, GC-FID and chiral GC. Linalool ranged from 27.3–42.2% and linalyl acetate from 27.2–46.6%.

Estrogenic Activity in Lavender and Tea Tree Oils, Part I & II
By: Brian M. Lawrence
A report entitled “Prepubertal Gynecomastia Linked to Lavender and Tea Tree Oils” appeared in the New England Journal of Medicine (Henley et al. 2007). The authors concluded that “repeated topical exposure to lavender and tea tree oils probably caused prepubertal gynecomastia in these boys.” To put the context of this paper into perspective it is worthwhile reviewing some information pertinent to this report.

Literature Review: The Debate over Rational Odor Design
By: Manuel Zarzo
The hypothesis of olfactory receptors as metalloproteins and the future of odorant design. In his recent volume, The Secret of Scent: Adventures in Perfume and the Science of Smell, Luca Turin describes his passion for perfume and his pursuit of olfactive mysteries. Turin re-broached the vibrational theory of olfaction and proposed a transduction mechanism of primary olfactory reception.

Mood Benefits of Fragrance
By: Craig Warren and Stephen Warrenburg
IFF developed an interest in aromatherapy in the early 1980s as a potential means for imparting a stress-reducing benefit to fragrance. Aromatherapy is an age-old practice of applying the healing benefits of certain aromatic essential oils. In the traditions of aromatherapy, specific essential oils are stress reducing, whereas others are energizing, and still others can have either effect, depending on the user's state of mind/body interaction. We reasoned that the best way to study the stress-reducing properities of fragrance would be to investigate their physiological effects.

The Chemistry of F&F: Physiological Coolants
By: Steve Pringle and David Brassington, Oxford Ch…
New materials and emerging applications. Physiological cooling agents act in a number of ways. In a flavor or fragrance they can be the first impact, leaving a cool sensation on the palate or skin prior to the main aroma being imparted.

Research article: Biotransformation of Unsaturated Aliphatic Aldehydes Using Baker’s Yeast
By: Ian Gatfield and Heinz-Jürgen Bertram
Actively fermenting baker’s yeast (Saccharomyces cerevisiae) not only converts aliphatic aldehydes to the corresponding alcohols, but also may reduce certain carbon-carbon double bonds in the same molecule. Furthermore, an in situ acyloin condensation reaction occurs; this bioconversion reaction gives rise to relatively good yields of unsaturated 2,3-diols, which have two carbon atoms more than the corresponding aliphatic aldehyde used as substrate. Baker’s yeast has been used as a reagent in organic synthesis since the beginning of the 20th century, when fundamental studies were initiated on the mechanism of formation of fusel alcohols from the corresponding l-amino acids during the formation of ethanol.

Main Verbal Responses During Human Olfaction
By: Mans Boelens and Harrie Boelens
Every living organism needs information for the maintenance of its life and species. To gather this information animals, including humans, possess senses.

The Search For Scent
Gliding silently across the canopy of a coastal rainforest in the Masoala Peninsula of northeastern Madagascar, Roman Kaiser knew he was on to something good. “Can you smell this unique scent of White Freesia and Robina — which tree might it be — we have to go closer,” Kaiser said to his ScentTrek teammate and Givaudan executive perfumer, Dave Apel.

A Mathematical Model For Odors Applied To Binary Odor Mixtures
By: Francis Maurin
This expanded mathematical model is a modification of Berglund’s model (1973).1 The modification explains the elimination of one odor by another, the synergy of odors of low intensity and the existence of odorless substances, which have deodorant properties.
