It has long been known that optically active stereoisomers—optical antipodes or enantiomers—can have different sensory qualities. The most illustrative examples of this phenomenon are the enantiomers of carvone and menthol.
Especially during the last decade the interest in the separation and determination of the sensory properties of natural enantiomers has resulted in a large number of publications. This increasing interest was initiated by the development of new chromatographic separation techniques on optically active stationary phases and arose from the need to prove the naturalness of certain enantiomers. Numerous enantiomers have already been isolated and/or synthesized and their sensory properties have been investigated. These sensory properties of the compounds concern their odor qualities and threshold values in certain media. Because the determination of the sensory properties is a rather subjective task due to intra- and inter-individual differences, it is not suprising that some confusion exists about these properties. The sensory properties of a series of volatile enantiomers, which are important in flavors and fragrances, will be discussed in this article.

A meditation on the art and science of flavor and fragrance creation. My friends often tell me that I do not look my age. Maybe they do it to please or flatter me, but may be it is true.

The need to communicate the facts about fragrance quality, integrity and safety to consumers. Recent assertions by consumer activists, environmental groups, anti-industry standard proponents and mainstream media are creating negative perceptions of fragrance that may have dire consequences for the fragrance industry. If facts about fragrance quality, integrity and safety are not widely shared and communicated, a very unpleasant image of the industry could prevail.

History, world consumption, synthetics, byproducts, substitutes and derivatives. l-Menthol can be described as unique in the aroma chemical world for the cooling sensation it imparts to the skin and mucous membranes. This cooling effect is far greater than that which could be explained by the cooling induced by the evaporation of a solvent off the skin, such as experienced with ethanol or hexane.

A continuing meditation on the art, craft, materials and techniques of fragrance creation. I have thought quite often that I am lucky because I live on the outskirts of Barcelona. Visitors believe that Barcelona is very beautiful—and it really is—but unfortunately most people just visit downtown.

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.

Inside perfume’s greatest story. The story of Chanel Nº5 begins in Moscow in 1912 with perfumer Ernest Beaux’s studies of the aldehyde used in Houbigant’s Quelques Fleurs. It continues in La Bocca and Cannes, France, and then is almost derailed by competition from an unlikely source.
