People may be visually oriented, but unconsciously we turn to other senses to simplify and de-stress our complicated existence. Fragrance is mysterious, ethereal and elusive. Yet it is rooted solidly in the physical world and can therefore be examined scientifically. The chemistry behind fragrance is complex and fascinating. How do you build fragrance molecules to withstand heat and water and to emerge from the wash cycle firmly affixed to clothes, not washed away as the machine drains itself, and so convey messages of perfumed reassurance to the wearer? Perhaps this book will help to explain.
