The importance of when and how fragrance chemicals are extracted in order to accurately reconstitute the scent of a flower. The alluring fragrances of flowers are the primary inspiration for new perfumes. In the quest to develop novel synthetic aroma chemicals, perfumers have increasingly relied upon the assistance of analytical chemists to help them identify major chemicals responsible for floral fragrances.

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.

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.

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.
