By Philip Kraft, Karl A. D. Swift

Examine is greater than ever valuable to the F&F with its consistent call for for innovation and its often altering developments. particularly, within the vintage and well-explored domain names of musks and amber odorants attention-grabbing new discoveries have been made purely very lately, which proves the unending probabilities within the look for new aroma chemical substances. This used to be additionally mirrored within the brand of the convention, which featured Ambrocenide? as a brand new strong ambery odorant that emerged from classical cedrene chemistry - and it truly is besides mirrored in 4 of the 16 convention papers which are amassed during this specified factor of Chemistry & Biodiversity. With its specialize in biorelevant chemical substances, Chemistry & Biodiversity was once predestined to post the varied spotlight papers of the 'flavours & fragrances' convention. perfume and body spray fabrics via definition elicit a organic reaction, function flexible signs, set off the feel of scent and style in numerous methods - and each odorant designis not anything greater than 'chemistry probing nature'. yet body spray Chemistry may also record or even safeguard the biodiversity of scents, as was once the subject of the lecture of Roman Kaiser, which have been released prematurely because the first complete paper of Chemistry & Biodiversity.
